High-low voltage heat dissipation electric appliance cabinet

Abstract

The invention discloses a high-low voltage heat dissipation electric appliance cabinet, which comprises a cabinet body and a cabinet door rotatably arranged on the cabinet body, a heat dissipation plate is arranged in the cabinet body, a heat dissipation sheet perpendicular to the heat dissipation plate is arranged on the heat dissipation plate, an electronic component placing plate is arranged above the heat dissipation sheet, a forward and reverse rotation waterproof motor is arranged on the electronic component placing plate, an exhaust fan is arranged at the bottom of the cabinet body, a dustproof net is arranged at the top of the cabinet body, a waterproof ceiling is arranged over the cabinet body, an electric fan is arranged in the waterproof ceiling, and heat dissipation grooves are evenly distributed in the two sides and the back face of the cabinet body respectively. According to the invention, the disadvantage of poor heat dissipation performance of an electric appliance cabinet in the current market is effectively solved, the rotatable lifting rod is adopted to be connected with the waterproof ceiling, the position of the waterproof ceiling can be adjusted according to different sunlight irradiation angles and inclination angles of rain, rainwater residue and direct sunlight can be better avoided, and the electric appliance cabinet is high in safety performance, long in service life and high in practicability.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electric cabinets, in particular to a high and low voltage heat dissipation electric cabinet. Background technique [0002] At present, the high and low voltage electrical appliances of high and low voltage electrical appliances refer to the voltage level, the rated voltage level series of the power system and power equipment. But the current high and low voltage electrical equipment, because the cooling effect is not good and not fast enough, when the temperature is too high, it will affect the normal operation of the electronic components in the high and low voltage electrical equipment, and even short circuit the electronic components in severe cases. However, in the prior art, the heat dissipation of the electrical box is only performed through simple air intake holes, and the electronic components in use cannot be fully dissipated. Contents of the invention [0003] The purpose...

Problems solved by technology

But the current high and low voltage electrical equipment, because the cooling effect is not good, and it is not fast enough. When the temperature is too high, it will affect the normal operation of the electronic components in the high and low voltage electrical equipment, and even short circuit the electronic components in severe cases.

However, in the prior art, the heat dissipation of the electrical box is only carried out through simple air intake holes, and it is impossible to fully dissipate heat from the electronic components in use.
