It should be understood that a drain hole is provided on the bottom case 110, and water drained from the scroll main body 210 and the evaporator 400 can be drained through the drain hole.

Optionally, a diameter of a cylinder determined by a rotation path of an outer edge of the impeller 222 of the blower 220 is set to be D, and a value of D ranges from 145mm to 170mm, for example, the diameter of the cylinder determined by the rotation path of the outer edge of the impeller 222 of the blower 220 may be 145mm, 150mm, 165mm, 170mm, or the like. Correspondingly, the inner diameter of the volute body 210 for accommodating the impeller 222 and the diameter of the impeller 222 range from 145mm to 170 mm.

The air conditioner air inlet case that this embodiment provided assembles to the automobile body after, and the motor shaft 221 level of volute subassembly 200 is laid, and the long-pending liquid of staying in volute main part 210 can be discharged from volute main part 210 smoothly under the wind-force effect, has improved ponding and has influenced the problem of air supply volume, and evaporimeter 400 air inlet is even, and the temperature field is little, and the stable performance is reliable. Meanwhile, the volute assembly 200, the evaporator 400 and the filter element 300 are arranged independently and can be taken out of the box shell 100, so that the volute assembly is convenient to replace and maintain, and the cost is low.

The embodiment also provides a vehicle-mounted air conditioning system and an automobile, wherein the vehicle-mounted air conditioning system comprises an air inlet box of an air conditioner, the automobile comprises a vehicle-mounted air conditioning system and an automobile body, and the box shell 100 is fixed on the automobile body.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
