PROBLEM TO BE SOLVED: To solve the problem that a the condensate is allowed to run on the surface of a heat exchanger when the exchanger is water-repellent, the condensate increases due to enlarging of a sub-heat exchanger mounted at an upper heat exchanger, and the condensate of the inclined upper exchanger is guided to a heat transfer tube side, so that the condensate is incompletely guided to a water receiver of a supply grill by making the condensate to flow to a lower heat exchanger. SOLUTION: In a heat exchanger 7 having a cutout at a predetermined position at fins 4 in a longitudinal direction, an upper heat exchanger 7a above the cutout 6 is inclined and set to a lower heat exchanger 7b below the cutout 6. An impermeable sealing material 8 for preventing passing of the air not heat exchanged by the cutout 6 of the fin 4 is provided, and the front end 8a of a sealing material 8 is extended from the surface of the exchanger 7. |
