Abstract:
It is intended to suppress occurrence of a crack in a fixed portion of a tube with respect to a tank. A plurality of tubes ( 4 A to  4 D) are fixed to a sidewall ( 9 ) in a state in which they penetrate through the sidewall ( 9 ) via respective ones of a plurality of through-holes ( 9 b ) formed in the sidewall ( 9 ) in such a manner as to be arrayed in a line along a longitudinal direction. A heat exchanger ( 1 ) comprises a protective member ( 5 ) fixed to the sidewall ( 9 ) to protect a nearest tube ( 4 A) nearest to an end wall ( 10 ) among the plurality of tubes ( 4 A to  4 D), wherein the protective member ( 5 ) has a barrier portion ( 13 ) interposed between the end wall ( 10 ) and an outlet-side end portion ( 4 b ) of the nearest tube ( 4 A) disposed inside the sidewall ( 9 ).

Claim (Index 7):
The heat exchanger as recited in  claim 6 , wherein the covering portion is formed with a fitting hole which penetrates through the covering section in a direction orthogonal to the axis and in which the end portion of the nearest tube is fitted.
