Abstract

An efficient heat dissipation electric appliance cabinet for electrical engineering comprises a cabinet body. A box body is arranged on the inner top wall of the cabinet body, a plurality of ventilation holes are evenly formed in the bottom of the box body, gas exchange assemblies are inserted into the inner walls of the two sides of the cabinet body, a square pipe is arranged in the cabinet body, and the square pipe is located between the two gas exchange assemblies. The two ends of the top of each gas exchange assembly communicate with the side surface of the box body and the top of the square pipe correspondingly, and a plurality of heat dissipation holes are evenly formed in the inner side of the square pipe. An air inlet pipe and an exhaust pipe are arranged on the outer side wall of each gas exchange assembly and arranged at the two ends of the side, away from the square pipe, of the gas exchange assembly. The design is not only good in heat dissipation effect, but also high in heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a high-efficiency heat dissipation electrical cabinet for electrical engineering, which is mainly suitable for increasing heat dissipation effect and heat dissipation efficiency. Background technique [0002] With the continuous development of intelligent power distribution, the requirements for power cabinets are getting higher and higher, such as PLC control cabinets, frequency conversion cabinets, etc., more and more precision components and power devices are used inside the power cabinets, and the more precise The more demanding the components are on the use environment, especially the temperature requirements, the high-power devices in the power cabinet will release a lot of heat when they work, and the heat must be dissipated in time. If the heat dissipation is not good, it will damage the power devices. Service life and safety of use. [0003] Chinese paten...
