Description

technical field [0001] The invention relates to a cooling system for a high-frequency high-voltage power supply. Background technique [0002] Due to the small size, high integration and high output power of the high-frequency high-voltage power supply, a large amount of heat will be generated during its operation, which needs to be removed in time to ensure the thermal stability of the high-frequency high-voltage power supply. The requirements are high, and a good heat dissipation system can ensure the stable performance of the high-frequency high-voltage power supply and improve the reliability of the high-frequency high-voltage power supply; the existing heat dissipation systems for high-frequency high-voltage power supplies mainly include oil cooling and air cooling. The cooling method dissipates heat from the transformer included in the high-frequency and high-voltage power supply, which is prone to seepage of transformer oil from the oil pump, which in turn contaminate...

[0002] Due to the small size, high integration and high output power of the high-frequency high-voltage power supply, a large amount of heat will be generated during its operation, which needs to be removed in time to ensure the thermal stability of the high-frequency high-voltage power supply. The requirements are high, and a good heat dissipation system can ensure the stable performance of the high-frequency high-voltage power supply and improve the reliability of the high-frequency high-voltage power supply; the existing heat dissipation systems for high-frequency high-voltage power supplies mainly include oil cooling and air cooling. The cooling method dissipates heat from the transformer included in the high-frequency and high-voltage power supply, and it is easy for the transformer oil to seep from the oil pump, thereby contaminating other electronic components in the high-frequency and high-voltage power supply; the cooling effect of the wind cooling method is not good, wasting electric energy
