In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The following is based on the attached Figure 1 To Attachment Fig.10 The utility model introduces a vehicle air conditioner provided by the utility model. The vehicle air conditioner is installed in a new energy vehicle, and can utilize the feature of ample installation space in the power compartment of the new energy vehicle to arrange part of the structure of the vehicle air conditioner in the power compartment, thereby improving the driving experience in the cockpit.

[0039] Specifically, Figures 1 to 3 As shown, the vehicle air conditioner includes an air inlet box, a volute and a distribution box. The air inlet box is arranged in the power compartment, the distribution box is connected to the cockpit, and the volute is connected and arranged between the air inlet box and the distribution box. A large-volume filter is arranged in the air inlet box, which can filter the air for a long time and efficiently, but the required installation space is large. A blower assembly 6 is arranged in the volute, and the blower assembly 6 can drive the air from the air inlet box into the vehicle air conditioner, and then enter the distribution box after passing through the air inlet box and the volute. A heat exchanger is arranged in the distribution box, and a refrigerant is arranged to flow in the heat exchanger. The refrigerant can absorb the heat of the air or output heat to the air, adjust the temperature of the air, and input it into the cockpit after adjustment.

[0040] Compared with traditional gasoline vehicles, the power compartment of new energy vehicles does not need to be equipped with parts such as engines and gearboxes that occupy a large space, and has a larger available installation space. The vehicle air conditioner provided by the utility model transfers the air inlet box from the cockpit to the power compartment, thereby avoiding the air inlet box from invading the internal space of the cockpit and isolating the noise of the air inlet box when taking in air in the power compartment, which not only optimizes the space size of the cockpit, but also reduces the impact of the air intake noise on passengers, thereby improving the comfort of the vehicle and the driving experience.

[0041] Preferably, if Figures 2 to 5 As shown, in this embodiment, the vehicle air conditioner includes a lower housing 9, and the lower housing 9 has a first part and a second part arranged in a horizontal direction, the first part is used to form an air inlet box, and the second part is used to install a volute.
