In a natural environment, a heat dissipation cabinet is configured to provide an outdoor physical working environment and safety assurance for a related device of a wireless communication station or a wired network station. A communication apparatus such as a base station apparatus, a power supply apparatus, and a transmission apparatus may be installed in the heat dissipation cabinet, and a heat dissipation effect of an electronic apparatus installed in the heat dissipation cabinet is ensured, so as to support normal operation of the electronic apparatus. A heat dissipation effect of an existing heat dissipation cabinet is limited, which causes poor heat dissipation of the electronic apparatus in the heat dissipation cabinet. <CIT> discloses a kind of forced draft outdoor cabinet. <CIT> discloses a kind of outdoor directly ventilated cabinet waterproof construction and rack.

The invention is defined by the features of claim <NUM>. Embodiments of this application provide a heat dissipation cabinet, so as to improve a heat dissipation effect of the heat dissipation cabinet, and ensure a heat dissipation effect of an electronic apparatus in the heat dissipation cabinet.

Embodiments of this application further provide a communication device.

According to a first aspect, an embodiment of this application provides a heat dissipation cabinet, and the heat dissipation cabinet includes a cabinet body, a cabinet door, and a baffle. The cabinet body includes a top wall and a bottom wall that are oppositely disposed, and a side wall connected between the top wall and the bottom wall. The cabinet door is installed at a position of the side wall in the cabinet body, and an air outlet passage is disposed in the cabinet body that is close to a position of the top wall. An air inlet component and an air outlet component are disposed in the cabinet door, and the air outlet component is located between the air inlet component and the top wall, and is located at one end of the air outlet passage. An electronic apparatus placement area is disposed in the cabinet body, and the baffle is disposed between the electronic apparatus placement area and the cabinet door. The baffle includes a first opening, so that air that enters through the air inlet component directly enters the electronic apparatus placement area through the first opening.

In the heat dissipation cabinet in this embodiment of this application, the baffle is disposed between the electronic apparatus placement area and the cabinet door, so that the air that enters through the air inlet component directly enters the electronic apparatus placement area through the first opening, so as to cool an electronic apparatus disposed in the electronic apparatus placement area. In addition, the air outlet passage is disposed at the position of the cabinet body that is close to the top wall, so that air that passes through the electronic apparatus is led from the air outlet passage to the air outlet component, and further the air (hot air) that passes through the electronic apparatus is discharged out of the cabinet body through the air outlet component. That is, the air outlet passage in this application can quickly and effectively collect and discharge the heated air that passes through the electronic apparatus out of the cabinet body, thereby effectively improving a heat dissipation effect of the heat dissipation cabinet and ensuring electrical performance of the electronic apparatus disposed in the heat dissipation cabinet. In other words, in this application, external air (cold air) is directly introducing into the electronic apparatus placement area by using the baffle, so as to prevent the external air from diffusing in any direction in the cabinet body, and finally entering the electronic apparatus placement area. In this process, temperature of the external air rises gradually, and finally, when the external air arrives at the electronic apparatus placement area, there is a problem that the heat dissipation effect of the electronic apparatus in the electronic apparatus placement area is not good. Directly introducing the external air into the electronic apparatus placement area can effectively prevent the air from heating up in a process in which the air does not enter the electronic apparatus placement area, and by disposing the air outlet passage, air (hot air) that passes through the electronic apparatus placement area can be rapidly discharged out of the cabinet body, thereby effectively preventing the hot air from flowing back to the electronic apparatus placement area, improving the heat dissipation effect of the electronic apparatus in the electronic apparatus placement area, and ensuring effective operation of the electronic apparatus. The baffle can further prevent the air (hot air) that passes through the electronic apparatus placement area from flowing back and mixing with the air (cold air) that enters from the air inlet component, thereby greatly improving the heat dissipation effect of the heat dissipation cabinet. Both the air inlet component and the air outlet component in this application are disposed on the cabinet door, which facilitates maintenance, simplifies a structure of the side wall, and reduces production costs and maintenance costs.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the air outlet passage includes a body and an air duct that penetrates the body. Two opposite ends of the body include a second opening and a third opening that communicate with the air duct, the second opening communicates with the air outlet component, and the third opening is located above the electronic apparatus placement area. The above part of the electronic apparatus disposition area is in a direction in which the electronic apparatus disposition area faces toward the top wall. The third opening is located between the top wall and the electronic apparatus placement area, so as to quickly collect and discharge the air that passes through the electronic apparatus placement area out of the cabinet body through the air duct, and prevent hot air from flowing back to the electronic apparatus placement area. In addition, air that enters the air duct is isolated from air outside the air duct, thereby effectively improving the heat dissipation effect of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the second opening and the third opening are disposed opposite to each other in a direction toward the cabinet door, so as to quickly collect and discharge the air that passes through the electronic apparatus placement area out of the cabinet body through the third opening, and prevent hot air from flowing back to the electronic apparatus placement area, thereby effectively improving the heat dissipation effect of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the third opening is disposed toward the electronic apparatus placement area, that is, the third opening is disposed toward the air that passes through the electronic apparatus placement area, so as to effectively and quickly collect and discharge the air that passes through the electronic apparatus placement area out of the cabinet body, and prevent hot air from flowing back to the electronic apparatus placement area, thereby effectively improving the heat dissipation effect of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, at least one extractor fan is disposed in the air outlet passage, and is configured to extract the air that passes through the electronic apparatus placement area. The extractor fan is disposed in the air outlet passage, so as to more effectively and quickly collect and discharge the air that passes through the electronic apparatus placement area out of the cabinet body, thereby improving a heat dissipation effect of the electronic apparatus in the electronic apparatus placement area.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the baffle includes a first baffle and a second baffle, and the first opening is located between the first baffle and the second baffle. The first baffle is disposed adjacent to the body, and the second baffle is located between the first baffle area and the bottom wall. That is, in this application, the first opening that exposes the electronic apparatus placement area is formed by disposing the first baffle and the second baffle at an interval, so that external air is directly introduced into the electronic apparatus placement area through the first opening, which can effectively prevent the air from heating up in a process in which the air does not enter the electronic apparatus placement area, and improve the heat dissipation effect of the electronic apparatus in the electronic apparatus placement area. The first baffle and the second baffle can further prevent the air that passes through the electronic apparatus placement area from flowing back and mixing with the air that enters from the air inlet component to heat the air that enters from the air inlet component, thereby greatly improving the heat dissipation effect of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, a width of the first opening in a direction from the bottom wall to the top wall is less than or equal to a width of the electronic apparatus placement area from the bottom wall to the top wall, so as to effectively avoid a case that the air does not directly enter the electronic apparatus placement area caused by an excessive large first opening, and prevent the air that passes through the electronic apparatus placement area from flowing back and mixing with the air that enters from the air inlet component to heat the air that enters from the air inlet component, thereby effectively improving the heat dissipation effect of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, a gap is formed between the side wall and each of the first baffle and the second baffle, so that the air that enters through the air inlet component enters the electronic apparatus placement area through the gap. For the electronic apparatus in which a direction of an internal air duct is parallel to a direction between two side walls that are connected to the cabinet door, the air that enters through the air inlet component enters the position of the side wall of the cabinet body by passing through the first baffle and the second baffle and bypassing the gap, and then enters the internal air duct of the electronic apparatus, so as to quickly cool the electronic apparatus. That is, the air in this application enters the electronic apparatus along the internal air duct of the electronic apparatus for heat dissipation, so as to effectively and quickly cool the electronic apparatus, and improve the heat dissipation effect of the electronic apparatus. In addition, the first baffle and the second baffle can further prevent the air that passes through the electronic apparatus placement area from flowing back and mixing with the air that enters from the air inlet component to heat the air that enters from the air inlet component, thereby greatly improving the heat dissipation effect of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the air inlet component includes a first cover and an air inlet fan, where the first cover includes accommodating space, and a fourth opening and a fifth opening that are located at two opposite ends of the first cover and communicate with the accommodating space, the air inlet fan is disposed on the fifth opening side, and the air inlet fan draws air outside the cabinet body into the cabinet body. That is, the air is drawn into the cabinet body through the air inlet component, that is, a positive pressure system is in the cabinet body. The air that enters the cabinet body heats up after passing through the electronic apparatus placement area, flows toward the top wall, and then is discharged out of the cabinet body through the air outlet component that is located close to the top wall. If the fan is disposed in the air outlet component, that is, the fan is configured to extract the air in the cabinet body, to form a negative pressure system in the cabinet body, the external air is drawn into the cabinet body through the air inlet component under a negative pressure effect. For the negative pressure system, the air not only can enter the cabinet body through the air inlet component, but also may enter the cabinet body through another screw hole in the cabinet body. Therefore, dust and water outside the cabinet body are drawn into the cabinet body through a hole such as a screw hole and a cable hole, which affects performance of an apparatus in the cabinet body. The positive pressure system in this application can effectively prevent the air from entering the cabinet body through a hole other than the air inlet component, and can effectively prevent the dust and the water outside the cabinet body from being drawn into the cabinet body through a hole such as a screw hole and a cable hole, thereby ensuring the performance of the apparatus in the cabinet body.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, a part of the first cover is located on an inner side of the cabinet door, and a part thereof is located on an outer side of the cabinet door. The fourth opening is located on the outer side of the cabinet door, and the fifth opening is located on the inner side of the cabinet door. Therefore, the air inlet component does not occupy excessive space in the cabinet body, and a capacity of the cabinet body is ensured. In addition, a part of the air inlet component protrudes from the outer side of the cabinet door, so as to ensure a clean appearance of the heat dissipation cabinet, and facilitate transportation of the heat dissipation cabinet, thereby avoiding bump and damage of the air inlet component during transportation and use.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the first cover is located on an inner side of the cabinet door, and the fourth opening communicates with the air inlet of the cabinet door. That is, the air inlet component does not protrude from an outer side of the cabinet door, so as to ensure a clean appearance of the heat dissipation cabinet, thereby avoiding bump and damage of the air inlet component during transportation and use. Alternatively, the first cover is located on an outer side of the cabinet door, and the fifth opening communicates with the air inlet of the cabinet door. That is, the air inlet component does not occupy space in the cabinet body, so as to ensure that the space in the cabinet body is large enough to meet a large capacity requirement of a customer.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the air inlet component further includes a filter, and the filter is located in the accommodating space and is located on a side of the air inlet fan that faces toward the fifth opening. The filter is configured to filter impurity in the external air, so as to prevent the impurity from entering the cabinet body and affecting the electrical performance of the electronic apparatus in the cabinet body, thereby improving service life of the electronic apparatus.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the filter includes a dustproof part and a first waterproof part, and the dustproof part is disposed closer to the air inlet fan relative to the first waterproof part, or the first waterproof part is disposed closer to the air inlet fan relative to the dustproof part. Therefore, dust and water are effectively prevented from entering the cabinet body, and the electrical performance of the electronic apparatus in the cabinet body is prevented from being affected by the dust and the water, thereby improving the service life of the electronic apparatus.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the air outlet component includes a second waterproof part, and the second waterproof part is configured to prevent water from entering the cabinet body, so as to prevent the water from affecting the electrical performance of the electronic apparatus in the cabinet body, and improve the service life of the electronic apparatus.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, there are a plurality of air outlet components and air inlet components, so as to implement different heat dissipation requirements.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the heat dissipation cabinet includes a temperature sensor and a controller, the temperature sensor is disposed in the electronic apparatus placement area, and the controller is electrically connected to the temperature sensor and the air inlet fan, so as to control a rotation speed of the air inlet fan based on temperature of the electronic apparatus.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the cabinet door is connected to a first cover plate and a second cover plate, the first cover plate is configured to open or close the air outlet component, and the second cover plate is configured to open or close the air inlet component, that is, the air inlet component or the air outlet component that is not in use may be closed, so as to ensure sealing in the cabinet body, effectively control air flow in the cabinet body, improve the heat dissipation effect of the heat dissipation cabinet, and reduce energy consumption of the heat dissipation cabinet during use, thereby reducing use costs.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, a driving part is disposed in the cabinet door, and the driving part is connected to the controller, the first cover plate, and the second cover plate to drive the first cover plate and the second cover plate to respectively open or close the air outlet component and the air inlet component, so that the first cover plate and the second cover plate can be automatically controlled by the controller, and user experience is improved.

That is, the bearing frame can assist in installing the electronic apparatus, and is further configured to fix the body, so as to avoid introducing a new structure to fix the body, simplify a structure of the heat dissipation cabinet, and reduce production costs of the heat dissipation cabinet.

According to the first aspect, in a possible implementation of the heat dissipation cabinet, the heat dissipation cabinet further includes an auxiliary air outlet component, and the auxiliary air outlet component is disposed in the middle of the cabinet door. That is, air that passes through the electronic apparatus located on the bottom wall can be discharged out of the cabinet body through the auxiliary air outlet component, so as to prevent hot air from being transmitted step by step between different electronic apparatuses and further affecting heat dissipation effects of other electronic apparatuses, thereby effectively improving an overall heat dissipation effect of a plurality of electronic apparatuses.

That is, the air outlet passage in this application can quickly and effectively collect and discharge the heated air that passes through the electronic apparatus out of the cabinet body, thereby effectively improving a heat dissipation effect of the heat dissipation cabinet and ensuring electrical performance of the electronic apparatus disposed in the heat dissipation cabinet. In other words, in this application, external air (cold air) is directly introducing into the electronic apparatus placement area by using the baffle, so as to prevent the external air from diffusing in any direction in the cabinet body, and finally entering the electronic apparatus placement area. In this process, temperature of the external air rises gradually, and finally, when the external air arrives at the electronic apparatus placement area, there is a problem that the heat dissipation effect of the electronic apparatus in the electronic apparatus placement area is not good.

As shown in <FIG> and <FIG>, a shape of the cabinet body <NUM> is a square cylinder. Specifically, there are three side walls <NUM>, and the three side walls <NUM> are sequentially connected to each other and form accommodating space with the top wall <NUM> and the bottom wall <NUM> to accommodate the electronic apparatus <NUM>. The cabinet door <NUM> is disposed on the side wall <NUM> at an opening of the accommodating space, and is opened or closed relative to the cabinet body <NUM> to open or close the accommodating space. A bearing frame (not shown in the figure) is disposed in the cabinet body <NUM>, and the bearing frame is, for example, formed by a plurality of square hole bars. An area of the bearing frame that is used to dispose the electronic apparatus <NUM> is the electronic apparatus placement area <NUM>, and the bearing frame is configured to install the electronic apparatus <NUM>, so that the electronic apparatus <NUM> is firmly disposed in the cabinet body <NUM>. Certainly, in another embodiment the bearing frame is not limited to the foregoing description, provided that the electronic apparatus <NUM> can be fastened or borne.

The cabinet door <NUM> is plate-shaped, is disposed on the side wall <NUM> by using a rotating structure such as a hinge, and may be opened or closed relative to the opening of the accommodating space. The cabinet door <NUM> includes an inner side <NUM> and an outer side <NUM>. The inner side <NUM> faces toward the accommodating space, and the outer side <NUM> faces away from the accommodating space. An air inlet and an air outlet that penetrate the inner side <NUM> and the outer side <NUM> are disposed on cabinet door <NUM>. The air inlet communicates with the air inlet component <NUM>, and the air outlet communicates with the air outlet component <NUM>, so that air outside the cabinet body <NUM> enters the cabinet body <NUM> through the air inlet component <NUM>, and air inside the cabinet body <NUM> is discharged out of the cabinet body <NUM> through the air outlet component <NUM>, thereby ensuring the heat dissipation performance of the heat dissipation cabinet <NUM>.

In this embodiment, there are two air inlet components <NUM>, and the two air inlet components <NUM> are disposed on the cabinet door <NUM> at an interval. The air inlet component <NUM> includes a first cover <NUM>, a filter <NUM>, and an air inlet fan <NUM>. The first cover <NUM> includes accommodating space <NUM>, and a fourth opening <NUM> and a fifth opening <NUM> that are located at two opposite ends of the first cover <NUM> and that communicate with the accommodating space <NUM>.

The air inlet fan <NUM> draws the air outside the cabinet body <NUM> into the cabinet body <NUM>. Specifically, the first cover <NUM> is located on the inner side <NUM> of the cabinet door <NUM>, and the fourth opening <NUM> communicates with the air inlet of the cabinet door <NUM>. That is, the air inlet component <NUM> does not protrude from the outer side <NUM> of the cabinet door <NUM>, so as to ensure a clean appearance of the heat dissipation cabinet <NUM>, and avoid bump and damage of the air inlet component <NUM> during transportation and use.

For the negative pressure system, the air not only can enter the cabinet body <NUM> through the air inlet component <NUM>, but also may enter the cabinet body <NUM> through another screw hole in the cabinet body <NUM>. Therefore, dust and water outside the cabinet body <NUM> are drawn into the cabinet body <NUM> through a hole such as a screw hole and a cable hole, which affects performance of an apparatus in the cabinet body <NUM>. The positive pressure system in this application can effectively prevent the air from entering the cabinet body <NUM> through a hole other than the air inlet component <NUM>, and can effectively prevent the dust and the water outside the cabinet body <NUM> from being drawn into the cabinet body <NUM> through a hole such as a screw hole and a cable hole, thereby ensuring the performance of the apparatus in the cabinet body <NUM>. Certainly, in another embodiment, the air inlet fan may alternatively be removed, and an air outlet fan is disposed on the air outlet component <NUM>, so that the heat dissipation cabinet <NUM> of the positive pressure system is switched to a heat dissipation cabinet of the negative pressure system.

Therefore, water and dust are effectively prevented from entering the cabinet body <NUM>, so as to prevent water and dust from affecting the electrical performance of the electronic apparatus <NUM> in the cabinet body <NUM>, and improve service life of the electronic apparatus <NUM>. Certainly, in another embodiment, the first waterproof part <NUM> is disposed closer to the air inlet fan <NUM> relative to the dustproof part <NUM>.

The baffle <NUM> includes a first baffle <NUM> and a second baffle <NUM>. Both the first baffle <NUM> and the second baffle <NUM> are plate-shaped. The first opening <NUM> is disposed between the first baffle <NUM> and the second baffle <NUM>, that is, the first baffle <NUM> and the second baffle <NUM> are disposed at an interval to form the first opening <NUM> that exposes the electronic apparatus placement area <NUM>, the first baffle <NUM> is disposed adjacent to the air outlet passage <NUM>, and the second baffle <NUM> is disposed between the first baffle <NUM> and the bottom wall <NUM>. Specifically, a side of the first baffle <NUM> that is close to the air outlet passage <NUM> is connected to the air outlet passage <NUM>, so as to cooperate with the air outlet passage <NUM> to avoid a case that the air that enters from the air inlet component <NUM> is directly discharged from the air outlet component <NUM> without passing through the electronic apparatus placement area <NUM>. Both the first baffle <NUM> and the second baffle <NUM> are fixed to the bearing frame, and are detachably connected to the bearing frame. The first baffle <NUM> and the second baffle <NUM> may further be formed by a plurality of sub-baffles (not shown in the figure). A size of the first opening <NUM> may be determined based on a volume of the electronic apparatus <NUM>. The size of the first opening <NUM> is changed by changing a quantity of sub-baffles of the first baffle <NUM> and the second baffle <NUM>, so that the size of the first opening <NUM> can be set based on an actual requirement. Certainly, in another embodiment, the first baffle <NUM> and the second baffle <NUM> may be alternatively disposed on another structure in the cabinet body <NUM>.

<FIG> is a schematic diagram of a flow direction of air in a cabinet body. Some structures of the heat dissipation cabinet <NUM> are not shown in <FIG>. Please refer to <FIG>. A direction of an internal air duct of the electronic apparatus <NUM> in <FIG> is a direction from the cabinet door <NUM> to the side wall <NUM> disposed opposite to the cabinet door <NUM>. It may be understood that, for example, the cabinet door <NUM> is a front side, the side wall <NUM> disposed opposite to the cabinet door <NUM> is a rear side, and the direction of the internal air duct of the electronic apparatus <NUM> is a direction from the front side to the rear side. When the electronic apparatus <NUM> is cooled, the external air enters the internal air duct of the electronic apparatus <NUM> through the first opening <NUM> after passing through the air inlet component <NUM> (a solid arrow part in <FIG>), so as to cool the electronic apparatus <NUM>. After the air that passes through the electronic apparatus <NUM> is discharged from the electronic apparatus <NUM>, some may flow back through an upper side and a lower side of the electronic apparatus <NUM>, that is, through a side that faces toward the top wall <NUM> and a side that faces toward the bottom wall <NUM> (a dashed arrow part in <FIG>). The back-flow air cannot mix with the air that enters from the air inlet component <NUM> because of disposing of the first baffle <NUM> and the second baffle <NUM>. It may be understood that the first opening <NUM> is formed by using the first baffle <NUM> and the second baffle <NUM>, so that external air is directly introduced into the electronic apparatus placement area <NUM> through the first opening <NUM>, which can effectively prevent the air from heating up in the process in which the air does not enter the electronic apparatus placement area <NUM> and improve the heat dissipation effect of the electronic apparatus <NUM> in the electronic apparatus placement area <NUM>. In addition, the first baffle <NUM> and the second baffle <NUM> can further prevent the air that passes through the electronic apparatus placement area <NUM> from flowing back and mixing with the air that enters from the air inlet component <NUM> to heat the air that enters from the air inlet component <NUM>, thereby greatly improving the heat dissipation effect of the heat dissipation cabinet <NUM>.

In this embodiment, a width of the first opening <NUM> in a direction from the bottom wall <NUM> to the top wall <NUM> is less than or equal to a width of the electronic apparatus placement area <NUM> from the bottom wall <NUM> to the top wall <NUM>, so as to effectively avoid a case that the air does not directly enter the electronic apparatus placement area <NUM> caused by an excessive large first opening <NUM>, and prevent the air that passes through the electronic apparatus placement area <NUM> from flowing back and mixing with the air that enters from the air inlet component <NUM> to heat the air that enters from the air inlet component <NUM>, thereby effectively improving the heat dissipation effect of the heat dissipation cabinet <NUM>. Certainly, in another embodiment, when a heat dissipation requirement is not high, the width of the first opening <NUM> in the direction from the bottom wall <NUM> to the top wall <NUM> may alternatively be greater than the width of the electronic apparatus placement area <NUM> from the bottom wall <NUM> to the top wall <NUM>.

<FIG> is a schematic diagram of another flow direction of air in a cabinet body. Some structures of the heat dissipation cabinet <NUM> are not shown in <FIG>. Please refer to <FIG>. A gap a is formed between the side wall <NUM> and each of the first baffle <NUM> and the second baffle <NUM>. Specifically, a gap a is formed between the baffle <NUM> and each of two side walls <NUM> adjacent to the baffle <NUM>, so that the air enters through the air inlet component <NUM> enters the electronic apparatus placement area <NUM> through the gap a. For the electronic apparatus <NUM> in which the direction of the internal air duct is parallel to a direction between two side walls <NUM> connected to the cabinet door <NUM>, it may be understood that, for example, the cabinet door <NUM> is the front side, the two side walls <NUM> connected to the cabinet door <NUM> are respectively a left side wall and a right side wall. The direction of the internal air duct of the electronic apparatus <NUM> is a direction from the left side wall to the right side wall, or the direction of the internal air duct of the electronic apparatus <NUM> is a direction from the right side wall to the left side wall. When the electronic apparatus <NUM> is cooled, the air that enters through the air inlet component <NUM> enters the position of the side wall <NUM> of the cabinet body <NUM> mainly by passing through the first baffle <NUM> and the second baffle <NUM> and bypassing the gap a, and then enters the internal air duct of the electronic apparatus <NUM>, so that the electronic apparatus <NUM> can be cooled quickly (a solid arrow part in <FIG>). After the air that passes through the electronic apparatus <NUM> is discharged from the electronic apparatus <NUM>, some may flow back through the upper side and the lower side of the electronic apparatus <NUM>, that is, through the side that faces toward the top wall <NUM> and the side that faces toward the bottom wall <NUM> (a dashed arrow part in <FIG>), and the back-flow air cannot mix with the air that enters from the air inlet component <NUM> because of disposing of the first baffle <NUM> and the second baffle <NUM>. That is, in this application, the air enters the electronic apparatus <NUM> along the internal air duct of the electronic apparatus <NUM> to perform heat dissipation, so that the electronic apparatus <NUM> can be quickly and effectively cooled, and the heat dissipation effect of the electronic apparatus <NUM> can be improved. In addition, the first baffle <NUM> and the second baffle <NUM> can further prevent the air that passes through the electronic apparatus placement area <NUM> from flowing back and mixing with the air that enters from the air inlet component <NUM> to heat the air that enters from the air inlet component <NUM>, thereby greatly improving the heat dissipation effect of the heat dissipation cabinet <NUM>. For the electronic apparatus <NUM> in which the direction of the internal air duct is the direction from the left side wall to the right side wall or the direction from the right side wall to the left side wall, because the direction of the internal air duct of the electronic apparatus <NUM> is not from the front to the rear, that is, there is no air inlet passage at the first opening <NUM> in the electronic apparatus <NUM>, and therefore, the air that enters from the air inlet component <NUM> does not enter the electronic apparatus <NUM> through the first opening <NUM> between the first baffle <NUM> and the second baffle <NUM>, but enters the electronic apparatus placement area <NUM> through the gap a, and further enters the internal air duct of the electronic apparatus <NUM> to cool the electronic apparatus <NUM>. Disposing manners of the first baffle <NUM> and the second baffle <NUM> in this application have a good heat dissipation effect on electronic apparatuses <NUM> with different directions of internal air ducts, and are widely applied. A gap is formed between the second baffle <NUM> and the bottom wall <NUM>, so that the air that enters through the air inlet component <NUM> enters the bottom wall <NUM> to cool a related heat emitting part disposed on the bottom wall <NUM>. Certainly, in another embodiment, a gap is formed between the baffle <NUM> and one of the side walls <NUM>. For the electronic apparatus <NUM> in which the direction of the internal air duct is parallel to the direction between the two side walls <NUM> connected to the cabinet door <NUM>, the first opening may not be disposed between the first baffle <NUM> and the second baffle <NUM>. The second baffle <NUM> may alternatively be connected to the bottom wall <NUM>.

Two opposite ends of the body <NUM> include a second opening <NUM> and a third opening <NUM> that communicate with the air duct <NUM>. Specifically, the second opening <NUM> and the third opening <NUM> are disposed opposite to each other in a direction toward the cabinet door <NUM>, the second opening <NUM> communicates with the air outlet component <NUM>, and the third opening <NUM> is located above the electronic apparatus placement area <NUM>. The above part of the electronic apparatus disposition area <NUM> is in a direction in which the electronic apparatus disposition area <NUM> faces toward the top wall <NUM>. The third opening <NUM> is located between the top wall <NUM> and the electronic apparatus placement area <NUM>, so as to quickly collect and discharge the air that passes through the electronic apparatus placement area <NUM> out of the cabinet body <NUM> through the air duct <NUM>, and prevent hot air from flowing back to the electronic apparatus placement area <NUM>. In addition, air that enters the air duct <NUM> is isolated from air outside the air duct <NUM>, thereby effectively improving the heat dissipation effect of the heat dissipation cabinet <NUM>. The body <NUM> is disposed on the bearing frame, so as to avoid introducing a new structure to fix the body <NUM>, simplify a structure of the heat dissipation cabinet <NUM>, and reduce production costs of the heat dissipation cabinet <NUM>. Certainly, in another embodiment, the third opening <NUM> may alternatively be placed toward the electronic apparatus placement area <NUM>. An extractor fan may further be disposed in the air duct <NUM>.

The seventh opening <NUM> communicates with the second opening <NUM> of the air outlet passage <NUM>, and the sixth opening <NUM> communicates with the air outlet of the cabinet door <NUM>. That is, the air outlet component <NUM> does not protrude from the outer side <NUM> of the cabinet door <NUM>, so as to ensure a clean appearance of the heat dissipation cabinet <NUM>, and avoid bump and damage of the air outlet component <NUM> during transportation and use. For example, the second waterproof part <NUM> is a waterproof structure such as a water barrier. The second waterproof part <NUM> is configured to prevent water from entering the cabinet body <NUM>, so as to prevent water from affecting the electrical performance of the electronic apparatus <NUM> in the cabinet body <NUM>, and improve the service life of the electronic apparatus <NUM>. Certainly, in another embodiment, a quantity of air outlet components <NUM> may be set based on an actual requirement, so as to implement different heat dissipation requirements. A dustproof part may be further disposed in the air outlet component <NUM>. The air outlet component <NUM> may alternatively be disposed on the outer side <NUM> of the cabinet door <NUM>, or a part of the air outlet component <NUM> is located on the inner side <NUM> of the cabinet door <NUM>, and a part thereof is located on the outer side <NUM> of the cabinet door <NUM>.

The heat dissipation cabinet <NUM> further includes a temperature sensor (not shown in the figure) and a controller (not shown in the figure). The temperature sensor is disposed in the electronic apparatus placement area <NUM>, and the controller is disposed in the accommodating space. The controller is electrically connected to the temperature sensor and the air inlet fan <NUM>, so as to control a rotation speed of the air inlet fan <NUM> based on temperature of the electronic apparatus <NUM>, so as to implement automatic control of a heat dissipation system and improve user experience.

In the heat dissipation cabinet <NUM> in this embodiment of this application, the baffle <NUM> is disposed between the electronic apparatus placement area <NUM> and the cabinet door <NUM>, so that the air that enters through the air inlet component <NUM> directly enters the electronic apparatus placement area <NUM> through the first opening <NUM>, so as to cool the electronic apparatus <NUM> disposed in the electronic apparatus placement area <NUM>.

In other words, in this application, external air (cold air) is directly introducing into the electronic apparatus placement area <NUM> by using the baffle <NUM>, so as to prevent the external air from diffusing in any direction in the cabinet body <NUM>, and finally entering the electronic apparatus placement area <NUM>. In this process, temperature of the external air rises gradually, and finally, when the external air arrives at the electronic apparatus placement area <NUM>, there is a problem that the heat dissipation effect of the electronic apparatus <NUM> in the electronic apparatus placement area <NUM> is not good. Directly introducing the external air into the electronic apparatus placement area <NUM> can effectively prevent the air from heating up in a process in which the air does not enter the electronic apparatus placement area <NUM>, and by disposing the air outlet passage <NUM>, air (hot air) that passes through the electronic apparatus placement area <NUM> can be rapidly discharged out of the cabinet body <NUM>, thereby effectively preventing the hot air from flowing back to the electronic apparatus placement area <NUM>, improving the heat dissipation effect of the electronic apparatus <NUM> in the electronic apparatus placement area <NUM>, and ensuring effective operation of the electronic apparatus <NUM>. The baffle <NUM> can further prevent the air (hot air) that passes through the electronic apparatus placement area <NUM> from flowing back and mixing with the air (cold air) that enters from the air inlet component <NUM>, thereby greatly improving the heat dissipation effect of the heat dissipation cabinet <NUM>. Temperature control apparatuses such as the air inlet component <NUM> and the air outlet component <NUM> in this application are all disposed on the cabinet door <NUM>, which facilitates maintenance. The heat dissipation cabinet <NUM> can further be smoothly switched among a direct ventilation system, a heat exchange system, and an air conditioner system by changing different forms of cabinet doors <NUM>, so as to meet different scenario requirements of a user, reduce maintenance costs, reduce user usage costs, and improve user experience.
