[0002] Existing on-site inverter boxes dissipate heat using cooling fans installed through openings in the top and sides of the box. Because the box's surface is ventilated, even with a dust cover, it still cannot meet the waterproof and dustproof requirements of outdoor boxes. Dust easily accumulates inside the box, shortening the service life of the inverter and other electrical components. In hot summer conditions, the cooling fan's air volume often fails to meet the inverter's heat dissipation requirements, causing severe overheating. [Utility Model Content]

[0005] Preferably, the heat dissipation mechanism includes a radiator, and connecting pipes are provided on both sides of the radiator. The connecting pipes pass through the corresponding box walls of the lower box body and communicate with the outside world, and a fan is provided in one of the connecting pipes.

[0006] Preferably, the water tank is provided with a water inlet, and the water inlet is provided with a cover.

[0008] Preferably, a liquid level sensor electrically connected to the PLC controller is provided in the water tank, and an alarm electrically connected to the PLC controller is provided on the upper box body.

[0009] The beneficial effects of this utility model include: This application utilizes a water-cooling design, using water as a heat exchange medium, which improves the heat dissipation of the inverter. This eliminates the need for ventilation holes on the enclosure surface, ensuring the enclosure's protection level and achieving better dust and water resistance under extreme operating conditions. Compared to existing technologies, this design offers improved dust and water resistance, extends the inverter's service life, and provides improved heat dissipation.
