Description

technical field [0001] The invention belongs to the technical field of power supply cooling, and in particular relates to an oil cooler for high-power and high-voltage electric vacuum devices. Background technique [0002] The power supply system for the auxiliary heating of China Circulator No. 2 A (HL-2A) Tokamak device needs to modulate the pulse high-power high-voltage output. It is necessary to cool the high-power high-voltage tetrode (electric vacuum element) used in the output modulator of the power supply system, and the dissipation power of the anode of the element alone reaches more than 4kw. The cooling of traditional high-power electric vacuum devices generally adopts air-cooling. Although the structure of the air-cooling system is relatively simple, the heat conduction efficiency of air is low. Compared with oil cooling, its thermal conductivity is lower. In addition, air cleanliness, temperature, humidity and air pressure have a great influence on the insulati...
