Deep-hole drilling is to drill several circular waterways on aluminum plate/copper plate through corresponding drill bits, which penetrate each other to form circulating waterways.
In the fields of power electronic control, conversion, drive, signal transmission and new energy, in order to pursue high-efficiency, low-noise and low-temperature operation, and subject to space constraints, heat dissipation becomes the biggest limitation of product development idealization, and liquid cooling heat dissipation technology becomes the preferred thermal management method.
The copper shovel-tooth heatsink is made of pure copper material with a thermal conductivity coefficient of 380W/k. Long strips of material are mechanically cut at a certain angle to create straight and consistent gaps, and repeating this process forms an ordered gap structure. This design is used for cooling high-power devices under forced air conditions. The copper shovel-tooth heatsink can effectively improve the heat dissipation performance of these devices and maintain appropriate temperatures during operation.
The aluminum shovel-tooth heatsink is designed to solve the bottleneck of high-density tooth profiles that cannot be molded easily. Long strips of material are mechanically cut at a certain angle to create straight and consistent gaps, and repeating this process forms an ordered gap structure. This design is used for cooling high-power devices under forced air conditions and can improve heat dissipation by 5-8% compared with fin-based heatsinks.
