ABSTRACT:
A charge air cooler is provided in which, in use, the charge air enters a finned tube block at very high temperatures creating a problem in that the lamella-type corrugated fins heat up abruptly and expand in the transverse direction. In order to eliminate the resulting risks of damage, the finned tube block on the air inlet side is provided with expansion joints extending in parallel to the tubes. The expansion joints extend only to a selected depth into the finned tube block in the air flow direction, which depth is selected such that the temperature of the charge air has already dropped there to such an extent that damage as a result of thermal expansions is no longer a concern.
