Electrical engineering power distribution cabinet heat radiation device

Abstract

The invention relates to the technical field of power distribution cabinet heat dissipation, and discloses an electrical engineering power distribution cabinet heat dissipation device. The device comprises a cabinet body, partition plates are fixedly connected to the left side wall and the right side wall of an inner cavity of the cabinet body, ventilation pipes are fixedly connected to the left side wall and the right side wall of the inner cavity of the cabinet body, and net plates are fixedly connected to the left side wall and the right side wall of the inner cavity of the cabinet body; and a supporting plate is fixedly mounted between the opposite sides of the two net plates. According to the electrical engineering power distribution cabinet heat dissipation device, the exhaust fan isstarted, air in the cabinet body is pumped in through the exhaust pipe and enters the connecting pipe through the exhaust fan to reach the heat exchange pipe, the air in the heat exchange pipe passesthrough the water tank, the air is cooled and then sent into the ventilation pipe through the air supply pipe, and therefore the cooled air is sprayed out of the air spraying opening to enable the power distribution cabinet to be cooled more thoroughly; if the temperature of the water tank rises for multiple times, the semiconductor chilling plate is electrified to reduce the water temperature, so air circulation can be caused, and the heat dissipation of the heat dissipation device is more perfect.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of a power distribution cabinet, in particular to a heat dissipation device for a power distribution cabinet in electrical engineering. Background technique [0002] The power distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The power distribution cabinet is the general name of the motor control center. , The motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control for the load. [0003] In the field of electrical engineering applications, the importance of power distribution cabinets cannot be overstated. However, beca...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cooling device for electrical engineering power distribution cabinets, which has the advantages of convenient dust removal and good heat dissipation, and solves the problem that most of the existing power distribution cabinets use cooling holes to dissipate heat, making the internal temperature If it cannot be dissipated in time, it will easily cause internal burnout, and the heat dissipation hole will be blocked by dust. If it is not cleaned for a long time, it will easily make the heat dissipation of the power distribution cabinet more difficult.
