RADIATING FIN AND INTEGRATED HEAT EXCHANGER THEREBY

摘要

PURPOSE: A radiating fin and an integrated heat exchanger thereby are provided to increase the rigidity of the radiating fin, and to reduce heat transfer between first and second heat exchangers by increasing the heat transfer passage with forming an extension part between first and second louver groups. CONSTITUTION: A radiating fin of a heat exchanger is composed of plural louver groups, and an extension part(131) expanding the connection passage between the louver groups to enlarge the heat exchange area with inflow air. First tubes(13) for moving a first heat exchange medium are stacked in a first heat exchanger, and second tubes(14) for flowing a second heat exchange medium at temperature different from temperature of the first heat exchange medium are stacked in a second heat exchanger. The first heat exchanger is integrally formed with the second heat exchanger, and the radiating fin is composed of a first louver group(110) inserted between the first and second tubes and formed in the first heat exchanger to enlarge the radiating area and a second louver group(120) formed in the second heat exchanger.
