Technical Field

[0002] A charging pile box transformer is a box-type substation designed specifically for electric vehicle charging piles. Its primary function is to convert AC power from the mains into DC power for electric vehicles. This equipment typically consists of key components such as a wiring cabinet, transformer, rectifier, filter, and control system, working together to ensure a stable, reliable, and safe power supply to the charging pile. Charging pile box transformers play a vital role in new energy vehicle charging facilities and are one of the key devices promoting green travel.

[0003] At present, charging pile box transformers are all equipped with a heat dissipation structure to dissipate heat internally, but the number of heat dissipation blowers or fans used is large, and all of them need to be turned on during the heat dissipation process of the charging pile to introduce external natural air into the interior. However, in hot weather, the internal heat exchange effect of the charging pile box transformer is poor, and it consumes more electricity, which increases the heat dissipation cost. For this reason, we propose a heat dissipation structure for the charging pile box transformer. Utility Model Content
