TECHNICAL FIELD

Embodiments of this application relate to the field of terminal devices, and more specifically, to a housing structure and a terminal device.

BACKGROUND

As notebook computers develop towards high performance and lightening and thinning, heat dissipation performance has become an important factor affecting notebook computer development.

Currently, a heat dissipation structure of a notebook computer includes a heat pipe, a heat sink, and a fan. The heat pipe is in contact with heat emitting components by using a heat conducting material. For example, the heat emitting components are a central processing unit (CPU) and a graphics processing unit (GPU). The heat pipe transfers heat on the heat emitting components to the heat sink, and the fan dissipates heat on the heat sink to an external environment through an air outlet.

However, as performance of notebook computers continuously increases, power consumption of the notebook computers also increases, and heat emitting components of the notebook computers generate more heat. As a result, a conventional heat dissipation structure cannot properly dissipate heat for the heat emitting components. In this way, a surface temperature of a notebook computer is high, and this affects a hand feeling of a user. In addition, heat emitting components automatically perform underclocking, for example, a central processing unit automatically reduces a frequency, and this affects user experience of the user.

SUMMARY

Embodiments of this application provide a housing structure and a terminal device, to better dissipate heat for a heat emitting component of a notebook computer.

The embodiments of this application are implemented as follows:

According to a first aspect, an embodiment of this application provides a housing structure. The housing structure includes a bottom shell and a lifting shell. A first end of the bottom shell is connected to a first end of the lifting shell, a second end of the bottom shell and a second end of the lifting shell are spaced by a first distance, and space between the bottom shell and the lifting shell forms a heat dissipation channel. A heat dissipation panel is disposed on the bottom shell, a first surface of the heat dissipation panel is in contact with a heat emitting component, and a second surface of the heat dissipation panel is located in the heat dissipation channel.

In the first aspect, the heat dissipation panel is disposed on the bottom shell, and the first surface of the heat dissipation panel is in contact with the heat emitting component, to transfer heat generated by the heat emitting component to the heat dissipation panel. Because the second surface of the heat dissipation panel is located in the heat dissipation channel formed by the bottom shell and the lifting shell, heat on the heat dissipation panel can be quickly carried away by air in the heat dissipation channel. Because the heat dissipation channel is communicated with an external environment, heat dissipated by the heat dissipation panel quickly flows to the external environment through the heat dissipation channel. Therefore, the housing structure provided in this embodiment of this application can better dissipate heat for the heat emitting component in the bottom shell.

In a possible implementation, the housing structure further includes a sliding assembly. The first end of the bottom shell and the first end of the lifting shell are hinged, and the second end of the bottom shell is connected to the second end of the lifting shell by using the sliding assembly. When the second end of the lifting shell and the second end of the bottom shell move relative to each other by using the sliding assembly, to be spaced by the first distance, the second end of the lifting shell and the second end of the bottom shell are fixedly connected by using the sliding assembly.

When a user does not need to dissipate heat for the heat emitting component in the bottom shell, the user may enable the housing structure to be in a closed state by using the sliding assembly. In this case, no heat dissipation channel is formed between the bottom shell and the lifting shell. When the user needs to dissipate heat for the heat emitting component in the bottom shell, the user may enable the housing structure to be in an open state by using the sliding assembly. In this case, the heat dissipation channel is formed between the bottom shell and the lifting shell. Therefore, in this embodiment of this application, the housing structure may be enabled to be in the open state or the closed state by using the sliding assembly, so that the housing structure provided in this embodiment of this application has higher flexibility.

In a possible implementation, the sliding assembly includes a sliding shaft and a sliding mechanical part, the sliding shaft is disposed at the second end of the bottom shell, and the sliding mechanical part is disposed at the second end of the lifting shell. A sliding slot and a blocking slot that are connected to each other are disposed on the sliding mechanical part, and the sliding shaft adapts to the sliding slot and the blocking slot. When the sliding shaft slides in the sliding slot to the blocking slot on the sliding mechanical part, the second end of the lifting shell and the second end of the bottom shell are spaced by the first distance, and the second end of the lifting shell is fixedly connected to the second end of the bottom shell by using the sliding shaft and the blocking slot.

In a possible implementation, a groove for accommodating the lifting shell is disposed on the bottom shell.

When the user does not need to dissipate heat for the heat emitting component in the bottom shell, the user may enable the housing structure to be in the closed state by using the sliding assembly. In this case, no heat dissipation channel is formed between the bottom shell and the lifting shell, and the lifting shell may be accommodated in the groove on the bottom shell, to save space for placing the housing structure.

In a possible implementation, the first end of the bottom shell is fixedly connected to the first end of the lifting shell.

In a possible implementation, a heat conducting material and a heat pipe are further disposed on the first surface of the heat dissipation panel. The first surface of the heat dissipation panel is in contact with the heat emitting component by using the heat conducting material and the heat pipe.

Because the heat conducting material and the heat pipe have better heat conducting property, the heat conducting material and the heat pipe can better transfer heat on the heat emitting component to the heat dissipation panel, so that the heat dissipation panel can more quickly transfer heat to the external environment.

In a possible implementation, a heat dissipation fin is further disposed on the second surface of the heat dissipation panel.

In a possible implementation, a heat dissipation fan is further disposed on the heat dissipation fin on the second surface of the heat dissipation panel.

The heat dissipation fin is disposed on the second surface of the heat dissipation panel. The heat dissipation fin increases a heat dissipation area of the heat dissipation panel, and the heat dissipation fin can quickly transfer heat on the heat dissipation panel to the external environment. In addition, the heat dissipation fan can blow cold air from the external environment to the heat dissipation fin, so that heat on the heat dissipation fin is dissipated more quickly.

In a possible implementation, at least one air vent is disposed on the heat dissipation panel.

The air vent disposed on the heat dissipation panel also can quickly transfer heat on the heat dissipation panel to the external environment.

According to a second aspect, an embodiment of this application provides a terminal device. The terminal device includes the housing structure disclosed in any one of the first aspect and the possible implementations of the first aspect.

When the second end of the lifting shell2and the second end of the bottom shell1move relative to each other by using the sliding assembly4, to be spaced by the first distance h, the second end of the lifting shell2and the second end of the bottom shell1are fixedly connected by using the sliding assembly4, as shown by the state inFIG.2. In other words, the housing structure is in the open state. The second end of the lifting shell2and the second end of the bottom shell1may move relative to each other by using the sliding assembly4, to be in contact with each other, as shown by the state inFIG.3. In other words, the housing structure is in the closed state.

In the embodiments shown inFIG.2andFIG.3, when a user does not need to dissipate heat for the heat emitting component12in the bottom shell1, the user may enable the housing structure to be in the closed state inFIG.3by using the sliding assembly4. In this case, no heat dissipation channel is formed between the bottom shell1and the lifting shell2.

The sliding shaft41adapts to the sliding slot421and the blocking slot422, that is, the sliding shaft41may slide in the sliding slot421, and the sliding shaft41may be fixed in the blocking slot422. When the sliding shaft41slides in the sliding slot421to the blocking slot422on the sliding mechanical part42, the second end of the lifting shell2and the second end of the bottom shell1are spaced by the first distance h, and the second end of the lifting shell2is fixedly connected to the second end of the bottom shell1by using the sliding shaft41and the blocking slot422. In this case, the sliding assembly4is in the state inFIG.2. In other words, the housing structure is in the open state. Certainly, the user may apply external force to enable the sliding shaft41to leave the blocking slot422and enter the sliding slot421.

The heat dissipation panel is disposed on the bottom shell, the first surface of the heat dissipation panel is in contact with the heat emitting component, and the second surface of the heat dissipation panel is located in the heat dissipation channel. In this solution, although the lifting shell cannot be accommodated in the bottom shell, heat dissipation can also be better performed for the heat emitting component in the bottom shell.
