汽车空调冷却风扇选型分析

冷却风扇不仅为发动机冷却系统提供足够的冷却风量,将发动机水箱内高温的冷却液冷却,同时,还为空调系统提供风量,将冷凝器内的高温高压气态制冷剂冷凝成中温高压液态制冷剂.基于某型号轿车,通过CFD分析冷凝器处风量分布及整车状态下空调性能试验来选择合适风扇,以满足汽车空调系统要求.

Effcet of cooling fan to air conditioning

Cooling fan not only provides the cooling system of engine with enough supply of air to cool down the high-temperature cooling liquid flowing through water tank,but also supplies air conditioning system with cooling air to cool down the refrigerant through the condenser,which changes from high-temperature and high pressure gas state into mid-temperature and high pressure liquid state.Based on a type of passenger vehicle,proper cooling fan was selected by combining air flow distribution through condenser by CFD analysis with air conditioning performance test in the vehicle state to meet the need of automotive air conditioning system.
