Description

Technical Field

[0001] This utility model relates to a wind-cooled heat dissipation structure for charging piles. Background Technology

[0002] With the rapid increase in the number of electric vehicles, the power density of charging piles is constantly increasing, and the heat generated during charging is also increasing. Existing charging piles mostly use natural cooling or simple air cooling, which suffers from low heat dissipation efficiency, unreasonable air duct design, easy dust accumulation, and high noise levels. Especially in long-term outdoor operating environments, dust and moisture can easily enter the equipment, leading to excessive temperature rise of power modules, shortened lifespan, or even failure. Furthermore, the fan installation structure of traditional charging piles often lacks vibration damping measures, resulting in significant operating noise and inconvenient maintenance and cleaning.

[0003] Therefore, there is an urgent need for a charging pile air-cooled heat dissipation structure with reasonable structure, excellent heat dissipation performance, and dustproof and waterproof functions to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a charging pile air-cooled heat dissipation structure.

The air inlet is equipped with a detachable composite dustproof and airflow guiding module; The equipment compartment is equipped with a power module, and a heat exchange plate is attached to the heat sink of the power module. The heat dissipation fins of the heat exchange plate extend into the air duct compartment and are located on the air intake path of the axial flow fan.

[0006] As a further improvement, the composite dustproof and airflow guiding module includes, from the outside to the inside, an air guide plate, fan blades, and a removable and washable dust cover. The air guide plate is provided with multiple inclined airflow guiding blades, which are used to cut the incoming air into multiple airflows, improve air flow and filtration performance, and the removable structure facilitates maintenance.

[0007] As a further improvement, the tilt angle of the guide vanes is 30°~60° to optimize the airflow angle and speed, reduce airflow resistance, and improve heat dissipation uniformity.

[0008] As a further improvement, one side of the heat spreader is tightly bonded to the substrate of the power module's heat sink using thermal grease, which reduces thermal resistance, improves heat conduction efficiency, and prevents hot spots from forming.

[0010] As a further improvement, the axial flow fan is mounted on the duct partition via a shock-absorbing pad, and the air outlet is equipped with louvers to reduce noise and vibration, and improve operational stability and environmental adaptability.

[0011] Beneficial effects: High heat dissipation efficiency: Through the linkage design of the heat dissipation plate and the air duct, the heat of the power module can be quickly conducted and carried away.

[0012] Airflow optimization: The composite dustproof and airflow guiding module cuts the air into multiple airflow streams, improving airflow uniformity.

[0013] Strong dust and water resistance: The dust cover at the air inlet is removable and washable, and the water-guiding design at the bottom of the air duct effectively prevents water accumulation.
