PROBLEM TO BE SOLVED: To provide an integral heat exchanger in which a structure is prevented from being produced and higher durability and reliability are ensured by permitting a dimensional change in thermal expansion and contraction of the heat exchanger. SOLUTION: A parallel integral heat exchanger 1 is adapted such that at least two heat exchangers 5, 9 having different applications are joined with each other with brazing such that the heat exchangers are disposed longitudinally in the direction of ventilation, and flow directions of the heat exchange medium flowing through both heat exchangers are mutually substantially perpendicular to each other. In the heat exchanger 1, for allowing a size change in thermal expansion of the heat exchanger 9 there is provided a non-brazed portion to which both heat exchangers 5, 9 are not brazed and fixed, and further there is provided thermal expansion/contraction allowable holding means 25 for allowably holding a size change in thermal expansion/contraction. |
