Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation of charging piles, and specifically to a moisture-proof air cooling mechanism for charging piles. Background Art

[0002] The air cooling mechanism of the charging pile is a device that uses a fan or other equipment to draw air into the charging pile and discharge the heat inside the charging pile through heat exchange. However, when used in a humid environment, the existing air cooling mechanism of the charging pile will send high-humidity air from the outside into the charging pile, causing the electrical components inside the charging pile to be exposed to high-humidity air for a long time, thus causing failures. Especially in the rainy season, the service life of the charging pile will be seriously affected.

[0003] In order to solve this problem, the prior art usually installs a dehumidifier inside the charging pile box. When the humidity of the surrounding air is too high, the dehumidifier is started to dehumidify the gas entering the charging box, and the dehumidified gas is sent into the charging box to dissipate heat for the equipment.

[0004] In order to reduce the volume of the charging pile box, the condenser of the existing charging pile dehumidifier is integrated and installed at the charging pile air inlet port. However, since the dehumidifier is not always in use and the condenser is always exposed to the air intake, dust and lint will cover the outer surface of the condenser over time. When the condenser needs to be used, the dehumidification efficiency will be greatly reduced due to the layer of stains covering the outer surface of the condenser. Summary of the invention

[0005] The present application provides a moisture-proof air cooling mechanism for a charging pile. The dehumidification mechanism can dehumidify and cool the high-temperature and high-humidity gas entering the charging pile. At the same time, the dehumidification mechanism has an independent air intake pipeline. When the dehumidifier is not in use, the air intake pipeline is closed, which can effectively avoid the problem of reduced dehumidification efficiency due to the condenser of the dehumidifier being exposed to the air for a long time and being contaminated with dust, and can effectively solve the problems in the background technology.
