<p>PROBLEM TO BE SOLVED: To prevent a decrease in a heat exchanging surface area while improving a heat exchanging efficiency by heat exchanging the air brought into an air gap between adjacent heat exchangers. SOLUTION: A first shield 30 for preventing passage of the air not heat exchanged and receiving condensate dropped along a second heat exchanger 18 is provided between a first heat exchanger 17 and the exchanger 18 disposed above and below, and a shield 32 is disposed to be brought into contact with a lower surface of the upper exchanger 18 of the adjacent exchangers 17, 18. A second shield 31 for preventing passage of the air not heat exchanged is provided between the exchanger 18 and a third heat exchanger 19, and disposed over upstream side opposed surfaces of the adjacent exchangers 18, 19. Vent holes 36, 40 for guiding the sucked air to the exchanges 17, 18, 19 are respectively formed at both the shields 30, 31.</p> |
