PURPOSE:To improve a heat exchanging efficiency in a plurality of V-shaped heat exchangers placed in adjacent to each other by a method wherein a plurality of V-shaped heat exchangers are disposed in such a way as a V-shaped extremity end at a downstream side heat exchanger is projected in the direction opposite to that after changing an air direction in an air flowing direction when the air is taken. CONSTITUTION:Two sets of V-shaped heat exchangers 3A, 3B are disposed such that the V-shaped heat exchanger 3B positioned at the downstream side in an air flowing direction when the air is taken is displaced more downwardly than the V-shaped heat exchanger 3A at the upstream side. As a result, due to a presence of a V-shaped extremity end (b) of the V-shaped heat exchanger 3B at the downstream side, a part of the heat exchanging air taken from the air inlet port 20 is bent and guided in the direction of changing air flow and further the heat exchanging air is guided into an intermediate spacing S defined by the downstream side surface of the V-shaped heat exchanger 3A at the upstream side and the upstream side surface of the V-shaped eat exchanger 3B at the downstream side. The air taking inlet port 20 is formed to open in opposition to almost all the surface of the air taking-in side of the V-shaped heat exchanger 3A at the upstream side. |
