PROBLEM TO BE SOLVED: To provide a heat exchanger with high capacity by increasing a fin pitch of one portion more than a fin pitch of another portion, and increasing an air volume passing between fins. SOLUTION: In the fin tube type heat exchanger 2 formed into a substantially L-shape and carrying out heat exchange between a coolant and air, the fin pitch of one portion is increased more than the fin pitch of the other portion, to be specific, a fin pitch of a bent part or a fin pitch of an end are increased more than other portions. Accordingly, the air capacity passing through the fins 5 is increased, and the capacity can be improved. COPYRIGHT: (C)2008,JPO&INPIT
