Abstract
In order to reliably eliminate gaps between a core and a tank arranged at both ends of a header-plate-less heat exchanger, and thus to ensure air-tightness and liquid-tightness of the tank, an upper fitting part and a lower fitting part of the tank protrude from a side plate part, and are deformable in the thickness direction, and those portions respectively make contact with and fit onto the inner surface of the uppermost and the lowermost tube, with the fitting parts being integrally soldered and secured.
