Abstract

The compact low-profile air conditioner unit is configured to be installed through the roof of a truck cabin, and run off of electrical power. The vehicle air conditioner includes a compressor, a blower fan, and a housing assembly. The housing assembly includes a mounting base having a top side and an opposing bottom side. The mounting base is configured to be mounted to a roof of a vehicle. The compressor and the blower fan are each mounted to the mounting base. When installed to the roof of the vehicle via the mounting base, the compressor and the blower fan each extend at least partially through the roof of the vehicle.

3. The vehicle air conditioner of claim 2, wherein the at least one of the plurality of air conditioning components includes a blower fan;

and wherein the housing assembly is configured such that, when the air conditioner is installed in the vehicle such that the mounting surface contacts the roof of the vehicle, a first portion of the blower fan extends above the roof of the vehicle, and a second portion of the blower fan extends through the opening in the roof of the vehicle and into the passenger compartment of the vehicle.

4. The vehicle air conditioner of claim 3, wherein the mounting base includes a second recess;

and wherein the blower fan is disposed at least partially within the second recess.

5. The vehicle air conditioner of claim 1, wherein the mounting base has opposing first and second sides;

and wherein the compressor extends through the mounting base from the first side to the second side.

6. The vehicle air conditioner of claim 5, wherein the at least one of the plurality of air conditioning components includes a blower fan;

and wherein the housing assembly is configured such that, when the air conditioner is installed in the vehicle such that the mounting surface contacts the roof of the vehicle, a first portion of the blower fan extends above the roof of the vehicle, and a second portion of the blower fan extends through the opening in the roof of the vehicle and into the passenger compartment of the vehicle.

7. The vehicle air conditioner of claim 6, wherein the blower fan extends through the mounting base from the first side to the second side.

8. The vehicle air conditioner of claim 1, wherein the housing assembly is configured such that, when the air conditioner is installed in the vehicle such that the mounting surface contacts the roof of the vehicle, the condenser is disposed above the roof of the vehicle.

9. The vehicle air conditioner of claim 1, further including an evaporator disposed at least partially within the housing assembly, wherein the housing assembly is configured such that, when the air conditioner is installed in the vehicle such that the mounting surface contacts the roof of the vehicle, the evaporator is disposed above the roof of the vehicle.

10. The vehicle air conditioner of claim 1, wherein the housing assembly is configured such that, when the air conditioner is installed in the vehicle such that the mounting surface contacts the roof of the vehicle, a first portion of the condenser extends above the roof of the vehicle, and a second portion of the condenser extends below the roof of the vehicle.

11. The vehicle air conditioner of claim 1, further including an evaporator disposed at least partially within the housing assembly, wherein the housing assembly is configured such that, when the air conditioner is installed in the vehicle such that the mounting surface contacts the roof of the vehicle, a first portion of the evaporator extends above the roof of the vehicle, and a second portion of the evaporator extends below the roof of the vehicle.

12. The vehicle air conditioner of claim 1, wherein the vehicle is a truck.

13. The vehicle air conditioner of claim 1, wherein the vehicle air conditioner is installed in a truck.

14. The vehicle air conditioner of claim 13, wherein the truck is a cab-over-engine truck.

15.
