Example Embodiment
[0031] Example 1
[0032] Such as figure 1 Shown: A heat dissipation method for charging piles. The inside of the cabinet of the charging pile is divided into a front compartment with a DC power distribution area and an AC power distribution area, and a rear compartment with power modules. The front compartment does not participate in circulating heat dissipation. The warehouse is divided into two left and right chambers by the module inlet and outlet air cooling cabin and the ventilation duct cabin. The power module is arranged in the module air inlet and outlet cooling cabin. The right chamber is divided into upper and lower chambers by the air duct partition. The structure makes the rear warehouse form a C-shaped air duct, which uses the circulating air in the C-shaped air duct to continuously take away the heat generated by the power module, and then exchanges heat with the cold air generated by the industrial air conditioner, reducing the temperature of the circulating air, a...
Example Embodiment
[0033] Example 2
[0034] Such as Figure 2-5 Shown: A heat dissipation method and circulation heat dissipation structure of a charging pile, including the cabinet body, the cabinet front door 1 and the left and right doors of the cabinet. The front door 1 of the cabinet is provided with a human-computer interaction area 18, and the inside of the cabinet body passes through an AC / DC mounting plate 2. It is divided into a front warehouse and a rear warehouse. The front warehouse is provided with a DC power distribution area 3 and an AC power distribution area 4 from top to bottom. The DC power distribution area 3 is equipped with a control module and a metering unit. The interior of the rear compartment is divided into two left and right chambers by the module inlet and outlet air cooling compartment 5 and the ventilation duct compartment 6 arranged from top to bottom. The compartment corresponding to the right door of the rear compartment is provided with the upper and lower comp...
