Description

Technical Field

[0001] The utility model relates to the technical field of VC soaking plate processing, in particular to a polishing device for VC soaking plate processing. Background Art

[0002] VC is generally called a heat spreader, or a temperature spreader. It is a heat dissipation element that uses the principle of phase change to achieve rapid heat conduction. VC (Vapor Chambers) is literally translated as a vapor chamber. In the industry, it is generally called a flat heat pipe, temperature spreader, or heat spreader. With the continuous improvement of chip power density, VC has been widely used in the heat dissipation of high-power devices such as CPU, NP, and ASIC. The inner wall of its VC heat sink has a microstructured vacuum cavity. Due to its high thermal conductivity, good temperature uniformity, thin thickness and easy integration, it has become the development trend of high-power LED integrated heat dissipation structure. In order to ensure the smooth use of the VC heat sink, the surface of the VC heat sink needs to be polished. During the polishing, the VC heat sink needs to be placed on a clamping mechanism for fixation, and then the surface of the VC heat sink is polished by the polishing mechanism. However, due to the fixation of the VC heat sink during polishing, the VC heat sink needs to be removed and turned over and clamped before the other side can be polished. This method reduces the efficiency of its polishing, and the clamped part of the VC heat sink cannot be polished, resulting in insufficient polishing. To this end, a polishing device for VC heat sink processing is proposed. Utility Model Content
