<p>PROBLEM TO BE SOLVED: To improve brazing properties while dealing with lightening by constituting a flange for supporting or forming piping for introducing and discharging a heat exchanging medium to be connected to a heat exchanger body of a hollow member. SOLUTION: A heat exchanger body 2 has a heat exchanger in which flat tubes 8 and fins 9 are alternately laminated, and side plates 10, 11 are connected to outsides of fins 9 of both ends. A U shaped channel is formed at the tube 8, and an inlet tank communicates with an outlet tank through a passage. A flange 14 is connected to an outside tank member 4 through a flange stay. The flange 14 is made of a hollow member, and made of a press-formed material. Thus, lightening can be obtained while improving brazing properties.</p> |
