Description

Technical Field

[0001] This utility model relates to the field of heat dissipation module technology, specifically a circular groove type VC heat dissipation module. Background Technology

[0002] With the maturation and further development of the electronics industry, users' demands for computer power are increasing, and the expansion of hardware and software and the increase in space occupied by them mean that, in order to generate high power, electronic components will inevitably release more heat, according to the principle of conservation of energy in physics.

[0003] Currently, most graphics card cooling modules on the market are flat-panel VCs (Vibration Cooling Modules). With continuous improvements in chip manufacturing processes, chip sizes are getting smaller and smaller, while heat generation is increasing. Under these circumstances, even using VCs to dissipate heat from the chip makes it difficult to improve cooling performance. Utility Model Content

[0004] The purpose of this utility model is to provide a circular groove type VC heat dissipation module, which has the advantages of simple structure, isolated design and good heat dissipation performance, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circular groove type VC heat dissipation module, comprising: a heat dissipation mechanism, the heat dissipation mechanism comprising a lower cover assembly and an upper cover assembly, wherein the upper cover assembly covers the lower cover assembly, the lower cover assembly comprises a lower cover body, the top of the lower cover body is provided with an evaporation chamber, the evaporation chamber is provided with a liquid storage chamber, the upper cover assembly comprises a heat spreader plate, and the heat spreader plate is provided with a plurality of heat conduction grooves.

[0006] Preferably, an arc-shaped flow guide surface is formed between the top of the lower cover body and the evaporation chamber, and an arc-shaped flow guide surface is formed between the evaporation chamber and the liquid storage chamber. Four mounting seats are provided at the bottom of the lower cover body.

[0007] Preferably, the depth of the evaporation chamber is between 1 and 2 mm.

[0008] Preferably, the depth of the liquid storage cavity is between 1 and 2 mm.

[0009] Preferably, each of the heat conduction grooves has a semi-circular vertical cross-section, and several heat conduction grooves are equidistantly opened on the heat spreader plate, with the distance between the edges of two adjacent heat conduction grooves being between 0.2 and 0.6 mm.

[0010] Preferably, protective gaps are provided between the heat conduction grooves on both sides of the plurality of heat conduction grooves and the two sides of the heat spreader.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model provides a circular groove type VC heat dissipation module, which includes a lower cover assembly and an upper cover assembly. The overall structure is simple and reasonably designed. The heat dissipation mechanism includes a lower cover assembly and an upper cover assembly, with the upper cover assembly covering the lower cover assembly. The lower cover assembly includes a lower cover body, with an evaporation chamber recessed at the top of the lower cover body. A liquid storage chamber is recessed inside the evaporation chamber. The upper cover assembly includes a heat spreader plate with several heat conduction grooves. Conventional VC has a small effective contact surface with the heat pipe. Because flat VC requires the heat pipe to be flattened, for a 6mm diameter heat pipe, the actual arc length of the single heat pipe in contact with the VC is only 5mm. The circular groove type VC can greatly increase the arc length of the contact with the heat pipe to about 9.42mm. Due to the higher heat transfer efficiency of the heat pipe and VC, the heat dissipation performance of the module is enhanced. Attached Figure Description
