ABSTRACT:
A laminated heat exchanger has a single tank structure and is of the type which does not have its fin holding portions in contact, but rather has them facing opposite each other over a specific gap. The structure of this heat exchanger ensures that the fins do not extend out of the gaps between the fin holding portions. The laminated heat exchanger has a single tank structure provided with tube elements constituted with tank portions formed by distending at one longitudinal end, and fin holding portions formed by bending at the other longitudinal end. Tanks are constituted on one side of the core by bonding adjacent tube elements. Each tube element of each adjacent pair of tube elements has a pair of fin holding portions facing opposite a pair of fin holding portions of the other tube element of the adjacent pair of tube elements over a specific gap. The distal ends of each pair of tube elements are non-aligned with one another, and thus, the gaps between opposing fin holding portions are non-aligned.
