ABSTRACT:
A laminate type heat exchanger includes a plurality of tubular elements each formed of a pair of generally flat stamped plates joined together in an abutting manner, a plurality of fins, the tubular elements and the fins being superposed one upon another in an alternate manner to form a laminate structure, and a pair of end plates attached to outermost ones of the tubular elements at opposite ends of the laminate structure. The end plates each have a joining section joined to an associated one of the outermost tubular elements, and a swelled main portion. The joining section of each end plate includes a joining portion abutting against a portion of one side surface of an associated outermost stamped plate, which portion corresponds in location to a portion of a recess formed in the other side surface of the associated outermost stamped plate. The joining portion is shaped and sized such that at least one row of depressions formed in the one side surface of the associated outermost stamped plate communicates with one of the interior of the swelled main portion of the end plate and the outside of the heat exchanger.
