Abstract
A gas/liquid heat exchanger comprises a stack of flat tubes, defining liquid flow passages. Spaces between the flat tubes define gas flow passages, with the sides of the core having an irregular comb-like arrangement. The heat exchanger further comprises a housing having side covers over the sides of the core, and being spaced from the sides of the core. The core has at least one portion of reduced width, so as to provide channels extending throughout the height of the core. The heat exchanger further comprises a pair of side seals at least partly received in the gap between the side cover of the housing and the core, and more particularly in the channels along the sides of the core. The side seal extends throughout the height of the core and has a thickness which is greater than that of the gap.
