Abstract
A heat exchanger of a plate construction, as used, for example, in a water-cooled charge air cooler with air-side lamella plates avoids undesirable thermal expansion effects which occur in the transient operation of a charge air cooler and result in damage. The otherwise completely hard-soldered cooler block is divided along a plane parallel to the plate planes into two or more partial blocks. When the partial blocks are combined at a mutual distance to form a cooler block assembly, each partial block receives a clearance in the transverse direction which compensates the thermally caused transverse expansions of the individual blocks.
