Description

Technical Field

[0001] The utility model relates to a CPU heat dissipation module, in particular to a lamp-type heat dissipation module. Background Art

[0002] With the advancement of semiconductor technology, the computing speed of computer central processing units (CPUs) has greatly increased in recent years. The heat released by the CPU during operation has also increased. Therefore, how to improve heat dissipation efficiency has become the primary task in the development of CPU cooling modules.

[0003] When a central processing unit (CPU) cooling module is in operation, the heat released by the CPU is transferred to the heat sink through a heat pipe. An axial-flow fan then blows air directly to the heat sink in a single direction, dissipating the heat. However, due to the small thickness of the axial-flow fan, its wind force and pressure are very low, and it can only blow air in one direction. Therefore, the heat on the heat sink cannot be blown away quickly, resulting in reduced cooling efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide a lamp-type heat dissipation module, which adopts a centrifugal fan. The thickness of the centrifugal fan is much greater than that of an ordinary axial flow fan, and it can provide greater wind force and air volume than an ordinary axial flow fan, and generate greater wind pressure, so that the heat transferred to the heat sink by the heat pipe can be blown out more quickly.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a lamp-type heat dissipation module, comprising a clip and a radiator assembly fixed on the clip, the clip comprising a back plate, two fixing rods symmetrical to the back plate and four positioning screws located on the back plate, a first positioning hole is provided at the four corners of the back plate, a first mounting hole and a second mounting hole is provided on each fixing rod, four first mounting holes and four second mounting holes are provided, the four positioning screws pass through the four second mounting holes respectively, and the four positioning screws are finally inserted into the four first positioning holes, the radiator assembly comprises a heat-conducting base, a heat pipe fixed on the heat-conducting base and a centrifugal fan arranged above the heat pipe, a heat-conducting part is arranged above the heat-conducting base, the heat-conducting part comprises a heat sink and a top plate and a bottom plate respectively fixed to the two ends of the heat sink, and the centrifugal fan is arranged on the inner side of the heat sink.

[0006] Preferably, the two fixing rods are symmetrical to the two ends of the back plate.

[0007] Preferably, the two first mounting holes on the fixing rod are located between the two second mounting holes, and the two second mounting holes are distributed at the edges of both ends of the fixing rod.

[0008] Preferably, two gaskets are provided on the upper end surface of each fixing rod, and the two gaskets correspond to the two second mounting holes respectively; the gaskets play a buffering role.

[0009] Preferably, there are two heat pipes, and the two heat pipes are symmetrical on the thermal base, and both heat pipes are fixed to the lower end surface of the thermal base; the height value of the lower end surface of the heat pipe is level with the height value of the lower end surface of the thermal base.

[0010] Preferably, both heat pipes extend from the bottom of the heat-conducting base to the upper end surface of the heat-conducting base, and the tops of both heat pipes are fixed to the upper end surface of the heat-conducting base.

[0011] Preferably, the heat conducting member further comprises a top cover, which is fixed on the top sheet; the top cover serves as a decoration.

[0012] Preferably, the radiator assembly also includes a fixing member, which includes an annular plate and a fan bracket fixed on the annular plate, and the centrifugal fan is installed below the fan bracket; four second positioning holes are provided on the fan bracket, and the fan bracket can be fixed to the annular plate by using four screws to pass through the second positioning holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. Compared with traditional air-cooled radiators, the present invention adopts a centrifugal fan. The thickness of the centrifugal fan is much larger than that of an ordinary axial flow fan. Therefore, it can provide greater wind force and air volume than an ordinary axial flow fan, and generate greater wind pressure, so that the heat transferred from the heat pipe to the heat sink can be blown out more quickly.

[0015] 2. In the present invention, the heat sink surrounds the outside of the centrifugal fan, so that the heat can be distributed in all directions of the heat sink. When the centrifugal fan is working, the heat can be blown out from all directions, thereby expanding the heat dissipation area and achieving better heat dissipation effect.
