In a common method, a louver structure is designed at an air inlet and an air outlet of a case to perform waterproof treatment, a filter is installed at the air inlet of the case to perform dustproof treatment, and a fan is installed at the air outlet of the case to realize heat dissipation of the internal environment of the case. Above-mentioned this kind of fill electric pile heat dissipation mode's shortcoming lies in using forced air cooling heat dissipation to require relatively higher to quick-witted case design protection level, and waterproof dustproof design is comparatively complicated, and improper handling can accelerate the device and become invalid, influences the life of equipment. The air inlet filter needs to be cleaned regularly, the later maintenance cost of the equipment is increased, and if the air inlet filter is not cleaned in time, the air inlet volume of the air inlet of the equipment can be reduced. In addition, if the equipment is continuously used for a long time, the heat dissipation efficiency of the heat dissipation mode is relatively low, and the heat dissipation requirement cannot be met in time. And because self mechanical vibration and air friction when the fan moves, the noise is great relatively, to high-power charging pile heat dissipation, needs increase fan rotational speed and increase fan quantity, but fan rotational speed is big more, and quantity is more, and the noise that produces is just big more, influences user experience. Meanwhile, the more fans, the higher the fan failure rate and the lower the reliability.
