When the device works, firstly, the blower blows the normal temperature gas at the air inlet 13 to the air outlet 14, in the process, the evaporator 3 takes away the heat in the normal temperature gas, and then the gas flowing out from the air outlet 14 is cold gas. When the air flows from the air inlet 13 to the impeller 41 of the blower, the air between the shunt pipe 5 and the housing 1 is divided into two parts, one part flows out from the shunt pipe 5 and further flows to the impeller 41 opposite to the shunt pipe 5, and the other part flows out from the gap between the shunt pipe 5 and the housing 1 and further flows to the impeller 41 opposite to the gap between the shunt pipe 5 and the housing 1. This arrangement not only makes the airflow distribution on the surface of the impeller 41 of the blower more uniform, but also makes the airflow distribution in the axial direction of the impeller 41 more uniform. The improvement of the internal flow field of the blower makes the rotation of the impeller 41 more stable, and has obvious noise reduction and abnormal sound improvement effects on the noise of the blower in the operation process. So that the low-noise air conditioner box meets the requirement on low noise of the air conditioner box of the automobile.

And the stability of the rotation of the impeller 41 can be further improved. If the bypass duct 5 and the impeller 41 are provided at a distance from each other in the axial direction of the impeller 41, the gas flowing out of the bypass duct 5 cannot be uniformly distributed in the ring surrounded by the plurality of blades 412 due to the diffusion of the gas itself.
