PURPOSE: A double heat exchanger with condenser and radiator is provided to prevent reduction of strength of a side plate and to reduce heat stress generated in tubes. CONSTITUTION: A double heat exchanger(100) includes a first core having a plurality of first tubes(111), through which first fluid flows, to perform heat exchange between the first fluid and air; both of first header tanks(113,114) placed at both of longitudinal ends of each of the first tubes to be fluidically connected with the first tubes; a second core having a plurality of second tubes, through which second fluid having temperature higher than that of the first fluid flows, and arranged in a line in an air flowing direction together with the first core to perform heat exchange between the second fluid and air; both of second header tanks placed at both of longitudinal ends of each of the second tubes to be fluidically connected with the second tubes; and a side plate(130) placed at one side of the first core and the second core to be connected with both of the first header tanks and both of the second header tanks at connection parts, extended in a direction parallel with the first tubes and the second tubes and having a flexible part(132) placed to be flexible at least at one side of the connecting part and a groove extending from one longitudinal end of the side plate to the flexible part in longitudinal direction of the side plate to separate the side plate from the one side of the connection parts so as to reinforce the first core and the second core. |
