Abstract
An angle member 9 is fixed to an insert 5 in a state in which a mounting portion 9a of the angle member 9 is fitted in a groove portion 5a depressed towards a core portion 4 side, whereby there is no case where an impact force applied to the angle member 9 and a connecting bar is transmitted directly to tubes 2, so that a possibility that a damage such as a crack is generated in the tubes 2 can be reduced. Consequently, the large vibration of a heat exchanging unit 7 can be suppressed while preventing the direct transmission of the impact force applied to the angle member 9 to the tubes 2.
Claims9
A heat exchanger comprising:
- a plurality of heat exchanging units each having a core portion comprising, a plurality of tubes through which coolant passes and inserts provided on both sides of the core portion in such a manner as to extend in parallel with a longitudinal direction of the tubes so as to reinforce the core portion;
- angle members fixed to the heat exchanging units at locations of the inserts which correspond to longitudinally intermediate portions of the tubes;
- and
- a connecting bar to which the angle member fixed to each of the plurality of heat exchanging units is connected.
