Abstract

The invention discloses a composite cooling radiator for an aviation transformer rectifier. The composite cooling radiator comprises a radiator frame and a liquid cooling heat dissipation structure arranged in the radiator frame. The two sides of the radiator frame are provided with air cooling heat dissipation structures, the upper surfaces of the liquid cooling heat dissipation structures are provided with heating devices, and the back faces of the liquid cooling heat dissipation structures are provided with liquid cooling flow channels matched with the heating devices. An air cooling flow channel is arranged on the outer surface of the air cooling heat dissipation structure. The radiator is provided with the independent liquid cooling channel and the independent air cooling channel, the full-load liquid cooling heat dissipation requirement and the half-load air cooling heat dissipation requirement of the high-power aviation transformer rectifier under the high-temperature condition can be met, the height of the air cooling channel is effectively reduced, the heat dissipation efficiency of the radiator is greatly improved, and the overall weight of the radiator structure is reduced; and popularization and application of the radiator structure are facilitated.

Description

technical field [0001] The invention relates to the technical field of high-power aviation transformer rectifiers, in particular to a composite cooling radiator for aviation transformer rectifiers. Background technique [0002] At present, as the requirements of aircraft for electrical power are getting higher and higher, the power of aviation transformer rectifiers has increased to nearly 100kW, and the thermal power consumption of transformers in transformer rectifiers is extremely large. In order to solve its heat dissipation problem, more consideration should be given to using liquid cooling radiators to dissipate heat. [0003] However, in order to improve the reliability of the equipment, it is necessary to ensure that the transformer rectifier can still work at half load after the liquid cooling fails. For this reason, air cooling and heat dissipation must be considered. Most of the existing heat dissipation equipment is a single heat dissipation method, and the heat ...
