PROBLEM TO BE SOLVED: To assuredly prevent tubes or the like from being bent without using a baking jig and to surely braze the tubes to radiating fins in a heat exchanger having a heat exchanging part provided with the tubes and the radiating fins which are alternately laminated. SOLUTION: Tubes 23 and radiating fins 25 are alternately laminated to form a heat exchanging part 1. Long size reinforcing members 29 are provided at both sides in the direction of the lamination of the heat exchanging part 21. Header plates 27 or header pipes are arranged at both sides in the longitudinal direction of the tubes 23 of the heat exchanging part 21 and inserted into the opened ends of the tubes. The reinforcing member 29 comprises a first long size reinforcing member 31 and a second long size reinforcing member 33 having a coefficient of linear expansion smaller than that of the first reinforcing member 31 and the first reinforcing member 31 is disposed nearer to the heat exchanging part 21 than the second reinforcing member 33. |
