Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a current heat dissipation device for a charging pile. Background Art

[0002] A large amount of heat will be generated during the operation of the charging pile.

Among DC fast charging piles, the three common types of charging piles are divided according to the heat dissipation technology, mainly air cooling, liquid cooling and natural heat dissipation.

[0003] For example, a charging pile heat dissipation device with the authorization announcement number "CN220163690U" can cool the charging module by injecting cold water into the box, and the cold water flows into the cooling water pipe through the pipe. When an open flame appears in the charging module, sand can be poured into the box, and the regulating valve can be opened. The valve can be controlled to open on the outside of the charging pile, and the sand can fall directly into the charging module through the pipe to extinguish the open flame. However, when the device dissipates heat for the charging pile, it only injects cold water into the charging pile so that the water inside the charging pile can reduce the internal temperature of the charging pile. However, the device does not have a reasonable circulation function for cold water. When the device cools the charging pile with cold water once, it needs to cool the cold water again before the next cooling zone can be carried out.
