Air-cooling heat dissipation structure of high-power modular power source

Abstract

The invention provides an air-cooling heat dissipation structure of a high-power modular power source. The high-power modular power source is provided with a cooling air channel; a cooling device is arranged in the cooling air channel; heat emitted by the main heat-emitting component of the high-power modular power source is transferred to the cooling air channel through a heat transfer device; and the transferred heat is transferred out from the power source through cold and heat exchange. According to the air-cooling heat dissipation structure of the high-power modular power source of the invention, the cooling air channel is arranged in a power source module unit; the cooling device is arranged in the cooling air channel; the heat emitted by the main heat-emitting component of the power source is transferred to the cooling air channel through the heat transfer device; the heat is transferred out from the power source through cold and heat exchange; and therefore, cold and heat separation of the power source module can be realized, and high-protection level heat dissipation can be realized.

Description

【Technical field】 [0001] The invention belongs to the field of power electronic power conversion, and in particular relates to an air-cooled heat dissipation structure and method of a high-power modular power supply. 【Background technique】 [0002] With the increasing popularity of electric vehicles in my country, the demand for charging pile construction has increased sharply, and a large number of charging piles and charging modules have rapidly flowed into the market. At present, most of the manufacturers that develop and produce modular charging power supply basically follow two traditional industries for their technical route: (1) power supply industry; (2) communication power supply industry. Most of the equipment in the above two traditional industries operates in an indoor environment, and the operating environment is good, without serious dust, humidity, and salt spray problems. Power module products basically use air cooling to dissipate heat, which inevitably exp...

AI Technical Summary

Problems solved by technology

Large dust, condensation caused by temperature difference between day and night, salt spray in coastal areas, sulfide near gas stations, etc., will inevitably corrode circuit boards and sensitive components severely

Although the current outdoor electric vehicle charging piles are basically designed according to the protection level of IP54, due to the contradiction between heat dissipation and protection, the protection effect is still not obvious, and frequent maintenance is required. At the same time, the actual service life of the charging equipment is greatly reduced.
