Passenger car air conditioning system and heat-radiating fan device applied by same

Abstract

The invention discloses a passenger car air conditioning system and a heat-radiating fan device applied by the same. The passenger car air conditioning system comprises a compressor arranged in a shell base, a parallel flow condenser, a parallel flow evaporator, a receiver drier, an H-shaped expansion valve, a condensing fan and a heat-radiating fan device, wherein the compressor, the parallel flow condenser, the receiver drier and the parallel flow evaporator form a circulating closed system through a pipeline, the heat-radiating fan device is communicated with the parallel flow evaporator, microchannels are arranged inside the parallel flow condenser and the parallel flow evaporator, the condensing fan is used for pulling air from inside to outside, and a high-pressure liquid refrigerating agent, which is relatively high in temperature and subjected to heat exchanging and cooling, is provided for the parallel flow evaporator by discharging heat exchanged with the parallel flow condenser out of the cavity.

Description

technical field [0001] The invention relates to the field of passenger car air conditioning, in particular to a passenger car air conditioning system and a cooling fan device used therein. Background technique [0002] The passenger car air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the passenger car. It can provide a comfortable riding environment for the passengers, reduce the driver's fatigue intensity and improve driving safety. The air conditioning unit has become one of the symbols to measure whether the car is fully functional. With the development of my country's urban public transport and tourism, a large number of air-conditioned buses are on the market, and there is an increasing demand for passenger car air-conditioning maintenance personnel. The existing passenger car air conditioner comprises a compressor, a condenser, a liquid storage drier, an expansion valve, a top cover, an evaporator and...

AI Technical Summary

Problems solved by technology

The existing passenger car air conditioner comprises a compressor, a condenser, a liquid storage drier, an expansion valve, a top cover, an evaporator and a blower, and the compressor, condenser, liquid storage drier, expansion valve, and evaporator are arranged between The pipes are connected into a closed system. The condenser and evaporator are all made of copper tubes and aluminum sheets with outdated technology. They are randomly arranged, and the heat dissipation effect is not good. The low efficiency affects the performance of the passenger car air conditioner, especially the high energy consumption.

[0003] When the air conditioner is not in use, it is easy to accumulate a lot of dust

This affects the operating performance of the equipment, and will shorten the service life of the equipment, reduce the stability and reliability of its operation
