Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly relates to a heat-dissipating charging pile. Background Art

[0002] A charging pile is an infrastructure device that provides electrical energy supply for electric vehicles, and is usually composed of a power management module, a charging module, a control system, a human-machine interaction interface, etc. After accessing the commercial power, it converts alternating current or direct current into electrical energy suitable for on-vehicle batteries through an internal power conversion device, and real-time monitors the charging status and safety parameters to ensure fast, stable and safe charging services for the vehicle.

[0003] In the prior art, the heat dissipation of the charging pile mainly relies on a fan at a fixed position inside the box to blow hot air. However, due to the non-adjustable installation position of the fan, the high-temperature gas inside the box often accumulates around the fan or other dead corners and cannot be effectively discharged. If the heat dissipation capacity is improved by increasing the number of fans, not only will the power consumption and operating load of the device be significantly increased, but also greater noise will be generated; in addition, in a high-temperature environment, relying solely on the convection cooling of these fixed-position fans is still difficult to reduce the box temperature to a safe range, affecting the reliability and service life of the charging pile.
