【Abstract】 The parallel flow type heat exchanger is usually equipped as the condenser of the automobile air conditioning system because of its incomparable virtues. The heat transfer and flow characteristics in the refrigerant side are different from those of traditional heat exchangers. The present paper provides an introduction and comparison on the structural characteristics and working principle of different types of condenser. It analyzes the heat transfer and flow mechanism on the condensation of the refrigerant in the multi port extruded tube of the parallel flow type condenser in details. It can provide efficient evidence to the study, design and check of this type of heat exchanger.更多还原
