FIELD OF THE INVENTION

The invention relates to an active heat-radiating structure, in particular to an active heat-radiating structure which can be attached to a passive heat-radiating part.

BACKGROUND OF THE INVENTION

The existing computer device is equipped with a plurality of electronic components in the internal space of a computer in order to pursue strong computing capability, but the installation of a large number of electronic components in a certain space will cause heat radiating of the components to be difficult. Although vertical radiators are commonly arranged in current computer devices in order to reduce the temperature of the components, it is still difficult to achieve the heat-radiating requirements of the components, so that an active heat-radiating component such as a fan and the like additionally arranged in a limited space becomes an important subject.

Thus, the U.S. Pat. No. 10,444,807 discloses a vertical radiator additionally attached with a fan. However, a fan frame body is required to be separated from a positioning hole by operating a pressing part, then the height of the whole fan is adjusted to a proper position, and the fan frame body is further clamped into another positioning hole to fix the fan. In this way, although the height of the fan relative to the vertical radiator can be adjusted to reduce the space occupied by the fan, the operation requires that the frame be completely separated from the radiator so that the fan can be moved, which is not convenient for a user to operate.

The detailed description and technical contents of the present invention are described below with reference to the drawings.

Referring toFIGS. 1 and 2, the present invention provides an active heat-radiating structure10which is attached to a passive heat-radiating part20, such as a vertical radiator (not shown), and the shape of the passive heat-radiating part20is not limited to that depicted in the figures herein.

Also, referring toFIGS. 2, 3, 4, and 5, the active heat-radiating structure10comprises a fan11, an outer frame12connected with the fan11, and two mounting members14,16. The outer frame12comprises two first connecting portions121,122respectively disposed at outer edges of the outer frame12and arranged in parallel with an interval. The two mounting members14,16are disposed on the passive heat-radiating part20and correspond to the two first connecting portions121,122; and the two mounting members14,16form a connecting relationship with the outer frame12to allow the fan11to be attached to the passive heat-radiating part20. Each of the mounting members14(16) comprises a first mounting portion141(161) facing the outer frame12, the position of each of the first mounting portions141(161) is determined by one of the first connecting portions121,122, and each of the first mounting portions141(161) is assembled with one of the first connecting portions121(122).

Further, each of the first connecting portions121(122) comprises a track123(124) and a guide groove125(126), wherein the track123(124) and the guide groove125(126) are arranged in parallel, and the position of the track123(124) and the guide groove125(126) are not limited. For example, the track123(124) is disposed at outer edges of the outer frame12relative to outer sides of the guide groove125(126), or disposed at inner sides of the outer frame12relative to the guide groove125(126). Also, a plurality of positioning points127(128) are provided on the track123(124). In an embodiment, the track123(124) is provided with a plurality of recesses arranged at intervals to form the plurality of positioning points127(128). In addition, each of the first mounting portions141(161) comprises at least one elastic sheet142(162) and a guide block143(163), wherein the elastic sheet142(162) is disposed at a position corresponding to the position of the track123(124), After the elastic sheet142(162) is assembled and positioned in the track123(124), the elastic sheet142(162) is clamped into one of the plurality of positioning points127(128), thereby the elastic sheet142(162) is stressed to move within the track123(124). Moreover, the guide block143(163) is disposed at a position corresponding to the position of the guide groove125(126), and the guide block143(163) is disposed in the guide groove125(126) and is stressed to slide in the guide groove125(126). For convenience of explanation to the invention hereinafter, the guide groove125(126) is disposed at outsides of the outer frame12relative to the track123(124), and the guide block143(163) is also disposed at outsides of one of the mounting members14(16) relative to the guide groove125(126).

Please refer toFIGS. 5, 6, and 7. In one embodiment, it is assumed that the relative height between the fan11and the passive heat-radiating part20is not adjusted initially, i.e. the relative distance between the fan11and the passive heat-radiating part20is minimum. At this time, the elastic sheet142(162) is clamped into one of the positioning points127(128), and the guide block143(163) is disposed in the guide groove125(126), so that the fan11can be fixedly attached to the passive heat-radiating part20. In addition, the elastic sheet142(162) is displaced along the track123(124) when the active heat-radiating structure10is pulled upward by an external force, and the elastic sheet142(162) is deformed by the track123(124) during the displacement, so that the elastic sheet142(162) is displaced from one of the plurality of positioning points127(128) which is located at a higher horizontal position toward another positioning points127(128) which is located at a lower horizontal position. On the other hand, each of the first connecting portions121(122) is also stressed by the external force, and the guide groove125(126) is displaced in a direction opposite to the passive heat-radiating part20such that a relative movement is appeared between the guide groove125(126) and the guide block143(163), thereby allowing the fan11to change the position relative to the passive heat-radiating part20without removal from the passive heat-radiating part20. Also, when the elastic sheet142(162) is displaced to the positioning points127(128) located at the lower horizontal position, the elastic sheet142(162) is recovered to its original shape by the elastic force thereof, so that the elastic sheet142(162) is clamped into and limited the positioning points127(128) located at the lower horizontal position and limited by the positioning point127(128). At this time, the relative distance between the fan11and the passive heat-radiating part20is larger, that is, the fan11is located at a horizontally higher position than the passive heat-radiating part20, as shown inFIG. 6. Thereafter, the elastic sheet142(162) is able to move continually in the track123(124) in accordance with the direction of the external force applied to the active heat-radiating structure10. For example, the elastic sheet142(162) is moved to be clamped into a position of one positioning point127(128) which is located at a lower horizontal position when the active heat-radiating structure10is pushed and displaced in a direction facing the passive heat-radiating part20. At the same time, the guide groove125(126) is also displaced in the direction facing the passive heat-radiating part20, causing a relative displacement between the guide block143(163) and the guide groove125(126). On the other hand, when the active heat-radiating structure10is stressed to be displaced in the direction opposite to the passive heat-radiating part20, the elastic sheet142(162) is moved to be clamped into a position of one positioning point127(128) which is located at a higher horizontal position, causing a relative displacement between the guide block143(163) and the guide groove125(126).

As described above, the first connecting portion121(122) of the present invention comprises the track123(124) and the guide groove125(126), and the first mounting portion141(161) comprises the elastic sheet142(162) and the guide block143(163). During an implementation, the guide block143(163) is disposed in the guide groove125(126) to limit the fan11, so that the fan11is prevented from being separated from the passive heat-radiating part20. Meanwhile, the elastic sheet142(162) is clamped into one of the plurality of positioning points127(128) of the track123(124), and the height of the fan11can be adjusted relative to the passive heat-radiating part20by changing the positioning point127(128) clamped into by the elastic sheet142(162). Referring toFIG. 8, the active heat-radiating structure10is provided with the first connecting portions121(122) and the first mounting portion141(161), so that the active heat-radiating structure10is attached to the passive heat-radiating part20and adjusted in height relative to the passive heat-radiating part20. Also, when the present invention is actually applied to a circuit board30, more external electronic components40(e.g., random access memory, RANI, etc.) is allowed to be mounted on the circuit board30by adjusting the height position of the active heat-radiating structure10, and the active heat-radiating structure10does not interfere with mounting positions of the external electronic components40.
