Automobile air-conditioner external unit device

Abstract

The invention relates to an automobile air-conditioner external unit device, which comprises an external unit casing, an air-conditioner compressor, a liquid storage tank and a condenser. The air-conditioner compressor, the liquid storage tank and the condenser are sequentially connected and disposed in the external unit casing. The air-conditioner compressor and the condenser are connected with an external device, the air-conditioner compressor is used for compressing and driving refrigerant to lead the refrigerant to be conveyed to the liquid storage tank which is used for storing the refrigerant, and the condenser is used for radiating and condensing the refrigerant conveyed by the liquid storage tank. Aiming at the defects of complex structure, large size and the like of the existing air-conditioner external unit, the automobile air-conditioner external unit device is simple in structure and small in size, and limited front space can be used reasonably; an electronic fan is mounted on one side of the external unit device, so that overheat is effectively avoided; and the external unit device can be used as an after-sale option optional part, a refrigerating air-conditioner can be additionally installed without demounting the external unit device, after-sale maintenance is convenient and cost is low.

Description

technical field [0001] The invention relates to an air conditioner external unit, in particular to an automobile air conditioner external unit. Background technique [0002] The automotive air conditioning system mainly includes a compressor, a condenser, a liquid receiver, an expansion valve, an evaporator, a fan, pipelines and control components, etc., all of which are located in the front compartment of the vehicle and connected by pipelines. It occupies a large area and has a complex structure. The compressor is the refrigerant cycle power source of the refrigeration system. When the compressor is working, it can compress the refrigerant gas into a high-pressure liquid state, and continuously promote the refrigerant cycle to complete the heat absorption and heat release process. The car air-conditioning compressor is usually driven by the engine and controlled by the pull-in and opening of the electromagnetic clutch behind the air-conditioning pulley. [0003] In gener...
