Waterproof heat dissipation structure of switch cabinet top plate

Abstract

The invention discloses a waterproof heat dissipation structure of a switch cabinet top plate. The waterproof heat dissipation structure comprises a switch cabinet body, the top plate, a rain bafflingplate and a heat dissipation frame. The top plate is fixedly arranged on the top of the switch cabinet body, the rain baffling plate is arranged above the top plate, the width and length of the rainbaffling plate are consistent with the those of the top plate respectively, slanted rain baffling edges are fixedly arranged around the rain baffling plate, and rubber sealing pads are fixedly arranged on the lower surfaces of the rain baffling edges. According to the waterproof heat dissipation structure of the switch cabinet top plate, the heat dissipation performance of the top plate of the switch cabinet body is good, heat is not easily collected at the top plate, and the phenomenon cannot occur that devices in a switch cabinet are influenced during use since the temperature is too high; aheat dissipation structure on the top plate is reasonable in design, a heat dissipation effect is achieved, good waterproof performance is also achieved at the same time, water does not easily enterthe switch cabinet, the rain baffling plate can ascend and descend, and more convenience is provided for changing the heat dissipation amount of the top plate and the rain baffling degree according toactual needs. The waterproof heat dissipation structure is convenient to use and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a waterproof heat dissipation structure for a top plate of a switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., and some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding, but this switchgear still has the following drawbacks in the actual use process: [0003] 1. A large amount of heat is easily accumulated at the top plate of the existing switch cabinet, and it is not easy to discharge. If the temperature is too high, it will affect the use of the internal devices of the switch...

AI Technical Summary

Problems solved by technology

[0003] 1. A large amount of heat is easy to accumulate on the roof of the existing switch cabinet, and it is not easy to discharge. If the temperature is too high, it will affect the use of the internal devices of the switch cabinet, and the heat dissipation is poor;

[0004] 2. Some switch cabinets also have cooling devices on the top plate, but the water resistance is poor, and the inside of the switch cabinet is prone to water leakage
