CONDENSER TUBE FOR VEHICLE AIR CONDITIONING SYSTEM

摘要

PURPOSE: A condenser tube for vehicle air conditioning system is provided to achieve an improved heat efficiency while allowing for a variety of designs due to increased tube counts. CONSTITUTION: A condenser tube(20) for fluid connecting fluid containing portions formed by a pair of headers and header tanks coupled to headers, respectively, is a metallic lamination formed of a pair of metallic materials having a low melting point, and has tube plates(30,40) with a plurality of flow bumpers(31) protruded from tube plates. At both widthwise ends of tube plates, bent and blocked portions are formed. A fluid pipeline is formed by brazing-coupling flow bumpers and bent and blocked portions of tube plates. Tube plates are configured to be bent along the line(L) formed in widthwise direction, and has free ends which are brazing-coupled so as to thereby form a closed tube.
