A switchgear with high heat dissipation efficiency

Abstract

The invention provides a switchgear with high heat dissipation efficiency, which includes a box body and a cyclone cooling device, the side of the box body is hinged with a box door, the bottom of the box body is slidably connected with a fixed plate, and the fixed plate is connected with a box matching the box body. The cover plate, the fixed plate is provided with a first ventilation pipe, the bottom of the first ventilation pipe is connected with an air guide pipe, the box body is provided with an air inlet pipe connected with the air guide pipe, and the inside of the first ventilation pipe is connected with a ventilation pipe. The fan and the cyclone cooling device are fixed above the first ventilation duct. The cyclone cooling device includes an outer cylinder, a second ventilation duct and an air guide tube. The air guide tube is arranged inside the outer cylinder, and the second ventilation duct communicates with the outer tube. , The outer cylinder, the second ventilation duct and the air guide tube are provided with cavities, the cavities are equipped with cooling liquid, and the box body is provided with a number of air outlets. The invention can evenly disperse and blow the wind blown by the ventilation fan to the cabinet through the cyclone cooling device, so as to realize sufficient heat dissipation of the switch cabinet, and the temperature decreases when the wind passes through the cyclone cooling device, so as to achieve a good heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of switch cabinets, in particular to a switch cabinet with high heat dissipation efficiency. Background technique [0002] The main function of the switch cabinet is to open and close, control and protect the electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system, so the normal operation of the switch cabinet is very important. [0003] The switchgear generates a lot of heat when it is working, which causes the ambient temperature in the switchgear to increase. Affected by the ambient temperature, the working performance of the components in the switchgear is reduced, which is prone to safety accidents, and working at high temperature for a long time will reduce the service life of the switchgear. , Traditional switch cabinets generally have cooling holes on the cabinet body, and cooling fans are installed in the sw...

[0003] The switchgear generates a lot of heat when it is working, which causes the ambient temperature in the switchgear to increase. Affected by the ambient temperature, the working performance of the components in the switchgear is reduced, which is prone to safety accidents, and working at high temperature for a long time will reduce the service life of the switchgear. , the traditional switch cabinet generally has cooling holes on the cabinet body, and cooling fans are installed in the switch cabinet, but this type of cooling method cannot fully dissipate heat, and the cooling effect is poor
