The water cooling assembly and the air cooling assembly are always in working states.

The working process of the heat dissipation system of the device combined with the working method is as follows:

when the weather is not rainy, the two conditions are divided, wherein in the first condition, when the weather is hot, the blower 404 is in an operating state, the blower 404 draws external wind into the charging post body 100, blows the external wind onto the inductance module 107 and the IGBT module 104 for heat dissipation, and finally blows the external wind out through the air outlet 103, and meanwhile, heat generated inside the charging post body 100 is absorbed and exchanged by cooling water in the water storage chamber 105 and the cooling chamber 108, so as to further promote the heat dissipation effect, wherein the temperature of the wind drawn from the outside by the blower 404 is high due to environmental factors, which is not beneficial to wind cooling heat dissipation, so that external hot wind enters through the hot wind area of the air inlet channel 400, and when the wind passes through the air cooling piece, the external hot wind is exchanged by the cooling water outside the air cooling piece, so that the temperature of the hot wind is reduced to be low-temperature wind relative to the external temperature, and finally enters the inside of the charging post body 100 through cold wind, and in the second condition, when the weather is cold weather, the underground is compared outside ambient temperature and is high, and consequently the temperature of endless cooling water can not be too low, and the outside cold wind temperature through air-cooled piece 403 and cooling water heat transfer improves simultaneously for the inside temperature of equipment can keep relatively stable temperature when the heat dissipation, has avoided the difference in temperature to cause equipment to damage too greatly. When the weather is rainy, the rain sensor senses whether the silt part has flowing water or not, if the silt part has flowing water, a signal is transmitted to the system controller which controls the blocking mechanism to operate to block the air inlet 101, and at this time, the equipment only uses the water cooling component to dissipate heat, thereby avoiding the short circuit of the equipment circuit caused by the water drops generated in the equipment because the air with high water content outside is sucked into the equipment, when water is at the bottom of silt, rainwater around the equipment is collected through the base 200 and flows onto the water cooling part 500 through the floor drain pipe 204, make the water heat exchange efficiency in the water-cooling piece 500 increase, improved the water-cooling radiating effect of equipment, if there is not mobile water, the rainwater inductor gives system controller with signal transmission, and system controller will check the mechanism and open, and air intake 101 is opened, throws away in the air this moment and has hydrous air, but its shortcoming can be neglected in equipment radiating efficiency improvement.

Meanwhile, the shape of the air outlet 103 of the device is improved, and external raindrops are effectively prevented from entering the device through combining the wind in the device which rapidly passes through the air outlet 103, and the device is simple in structure and easy to implement.
