Abstract

The invention relates to a heat dissipation device and a heat dissipation module for a power device. The heat dissipation device for the power device includes a heat dissipation main body, a first working medium partition plate, a second working medium partition plate, a first cover plate, a second cover plate, a liquid inlet pipe and a liquid outlet pipe. According to the invention, the contact area of the power device and heat pipes and the heat exchange area between working medium flow channels and cooling fluid channels are effectively amplified, the thermal resistance between the workingmedium flow channels and slots is extremely small, the heat dissipation efficiency of the power device is high, and the heat dissipation device and the heat dissipation module are suitable for heat dissipation of a large power device. Laminated arrangement of the slots, the working medium flow channels and the cooling fluid channels are utilized to replace welding of multiple heat dissipation plates, a water inlet main pipe and a water discharge main pipe in the prior art, and therefore, excessive welding points can be avoided, manufacturing process is simple, the cost is low, the thermal resistance can be effectively reduced, the risk of cooling fluid leakage is reduced, and the heat dissipation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power device heat dissipation, and in particular relates to a power device heat dissipation device and a power device heat dissipation module. Background technique [0002] Power devices (such as IGBTs) have certain losses during operation, and most of the losses turn into heat. In the actual application process, IGBT, as a power device, is widely used in frequency converters, inverters, electric vehicles and other fields. IGBTs will generate large losses during operation, and these losses are usually manifested as heat. In order for the IGBT to work normally, it is necessary to add a cooling device. The most commonly used is to install the IGBT in the middle of the radiator, and use the radiator to dissipate the heat to the surrounding space. If necessary, add a cooling fan or water cooling to increase the cooling efficiency. In addition, in order to reduce the temperature of the IGBT during operation, ...
