<p><P>PROBLEM TO BE SOLVED: To provide an evaporator capable of preventing degradation of cooling performance over a long time. <P>SOLUTION: This evaporator 1 is provided with: a plurality of fin groups 3 each comprising a plurality of plate fins 2 made of aluminum and arranged at intervals in the ventilation direction; a first heat exchange tube 4 comprising a plurality of straight tube parts 5 fixed to the plate fins 2 of the respective fin groups 3 in a piercing form and bent tube parts 6 and 7 each connecting two of the straight tube parts 5 adjacent to each other; and a second heat exchange tube 8 comprising a plurality of straight tube parts 9 and bent tube parts 11 and 12 each connecting two of the straight tube parts 9 adjacent to each other and connected to one end of the first heat exchange tube 4. Cutouts 17 are formed at corner parts of the plate fins 2 of two of the fin groups 3 adjacent to each other. Fitting-in parts 19 are formed by the cutouts 17 of the plate fins 2 of both the fin groups 3 adjacent to each other in the airflow direction. The straight tube parts 9 of the second heat exchange tube 8 are brought into contact with the plate fins 2 of both the fin groups 3 in a state fitted in the fitting-in parts 19. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
