Oil cooling high-frequency power supply

The utility model discloses an oil cooling high-frequency power supply. The oil cooling high-frequency power supply is composed of a compressor (1), a coaxial heat exchanger, a high-frequency rectifier (4) and an oil pump (5); the coaxial heat exchanger is provided with an air cooling pipe (2) and an oil pipe (3) to perform heat exchange, the air cooling pipe (2) is communicated with the compressor (1) to perform refrigeration, and the oil pipe (3) encircles the high-frequency rectifier (4) to bring away heat generated by the power supply into the coaxial heat exchanger and then performs the heat exchange with the air cooling pipe (2). The oil cooling high-frequency power supply adopts an active refrigeration and heat-radiation mode and cancels heat radiation fins, and then the effects of rapid heat radiation and occupied land area reduction are achieved.
