Radiator for high-voltage transformer oil tank and power module

Abstract

The invention relates to the technical field of heat dissipation, in particular to a radiator for a high-voltage transformer oil tank and a power module. The radiator comprises a base plate and a copper pipe. The surface of the base plate is provided with a bent groove. The copper pipe is embedded in the groove. The gap where the groove makes contact with the copper pipe is filled with high thermal conductivity materials. The surface, opposite to the surface provided with the groove, of the radiator is tightly attached to the transformer oil tank. The power module is mounted on the copper pipe. Since the high-voltage transformer oil tank and the power module adopt the same radiator for heat dissipation, only one liquid path is needed for being connected with a cooling liquid, liquid path connection connectors are reduced, and the situation that the liquid is leaked from the liquid path to burn out a power supply is prevented. No water flows in the oil tank, and therefore the situation that water enters the high-voltage transformer oil tank to burn out a high-voltage transformer is prevented.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation device for an oil tank of a high-voltage transformer and a power module. Background technique [0002] Devices such as high-power high-voltage laser power supplies generally contain heat-generating components such as high-voltage transformers and power modules. There are transformer oil and high-voltage transformer in the high-voltage transformer oil tank. The high-voltage transformer generates a lot of heat, and the oil tank needs to dissipate heat. No liquid can enter the high-voltage transformer oil tank. If liquid enters, the high-voltage transformer in the high-voltage transformer oil tank will be burned out. The power module has high power and generates a lot of heat, so it needs heat dissipation to work reliably. The high-voltage transformer oil tank and power module have good heat dissipation, the temperature of the high-voltage transformer o...
