Description

[0002] Similar equipment currently in use, if it is to achieve cooling and heat dissipation inside the electric control box, generally adopts conventional cooling fans or heat sinks to achieve the cooling effect. However, this kind of reciprocal cooling and heat dissipation electric control box completely isolates the inside of the electric box from the outside air, and achieves the cooling and heat dissipation effect through heat transfer between the inside and outside of the electric box.

[0003] The first type of heat dissipation method for electric boxes mentioned above is widely used in the market. Fans and heat sinks are usually used for general electric box heat dissipation. The disadvantage is that the inside and outside of the electric box must be ventilated, and it is generally equipped with air inlets and outlets. Usually, this heat dissipation effect is related to external temperature changes. When the external air temperature is high, the heat dissipation effect is not obvious, making it impossible to maintain a constant temperature in the electric box. In addition, if the external air contains moisture or corrosive gases, it is more likely to affect the life of components in the electric box. Summary of the invention
