Problems solved by technology

[0002] Outdoor photovoltaic inverters must solve the problems of waterproof, dustproof, and heat dissipation. Different manufacturers have different solutions. Many manufacturers add fans and radiators to the inverter cabinet to dissipate heat from the inverter heat source. Some Manufacturers open ventilation holes on the door panels, but the ventilation holes need to be waterproof and dustproof; the filter at the through holes has a certain blocking effect on the wind force of the fan, which will inevitably reduce the air volume and reduce the inverter’s operating efficiency. Heat dissipation effect: Some manufacturers place the fan at the bottom of the cabinet to blow air to the radiator, and the inverter as a whole enters the air from the bottom and exits from the top, so that it is easy to bring external dust into the inverter, resulting in pollution to the working environment of the inverter grade increase

Abstract

The invention provides a heat radiating structure of an outdoor type inverter cabinet body. The heat radiating structure of the outdoor type inverter cabinet body comprises a top cover (1) of the inverter cabinet body, a backboard (2) of the inverter cabinet body, an air duct (3), a radiator (4) and a fan (5). The top cover is arranged on the top of the inverter cabinet body. The top cover comprises an air inlet hole (11) formed in the front bending position below the top cover, an air outlet hole (13) formed in the back bending position below the top cover and a partition board (12), wherein the partition board is arranged in the middle of the top cover and separates the air inlet hole (11) and the air outlet hole (13). The backboard is arranged on the back of the inverter cabinet body, a vent hole is formed in the backboard, the air duct is arranged inside the inverter cabinet body and provided with an air outlet (31), the radiator is arranged below the air outlet (31), and the fan is arranged below the radiator. The invention further provides the outdoor type inverter cabinet body which comprises the heat radiating structure.
