Abstract

The invention provides power electronic equipment, a cabinet body thereof and a cabinet door of the cabinet body. An up-down interlayer passage parallel to the cabinet door is arranged on the back surface of a door panel of the cabinet door and forms a backflow passage, an upper port of the backflow passage is serially connected with draught fans, the backflow passage is connected with a radiating air channel formed by an internal space of the cabinet body to form a circulating passage, heat exchangers are arranged in the circulating passage, and a clapboard for assembling the power electronic equipment is further arranged in the cabinet body and is provided with vent holes. According to the invention, the cabinet body has a simpler structure, the elements in the cabinet body are convenient to maintain, and the working reliability and service life of the power electronic equipment are improved and prolonged.

Description

technical field [0001] The invention relates to the field of power electronic equipment. Background technique [0002] With the development of the new energy industry, the power level and operating environment requirements of power electronic equipment are becoming more and more stringent. The high power loss of power electronic devices under high power level working conditions will generate a lot of heat, which will make the temperature rise of power electronic devices very high. High, because temperature is one of the important factors that limit the service life of power electronic devices, the higher the device temperature, the shorter its service life, so the heat dissipation performance of power electronic equipment has become one of the important factors affecting the service life of power electronic devices. [0003] A patent document "A Power Electronic Equipment Cooling System" with the application number of 201120069000.9 discloses a power electronic equipment coo...
