[0025] Working principle:

[0026] The vehicle water circulation is cooled by the water radiator 21, and the high-temperature air flow after being supercharged by the vehicle turbocharging system is cooled by the intercooler 22.

Each air distribution cavity is provided with a fan 3, which can prevent the air from leaking between the fans 3, ensuring that the air volume of each fan 3 is evenly distributed. The variable-frequency motor 7 drives the fan 3 to rotate, and the air flow is diverted from the lower part of the air guide hood 41 into the air distribution cavity through the air guide hood retaining ring 43 to evenly cool the water radiator 21 and the intercooler 22. The corresponding variable-frequency motor 7, fan 3 and motor support assembly 5 form a fan unit, and each fan unit is separated separately. When a problem occurs in a certain fan unit, it can be disassembled separately for easy maintenance.
