Abstract
Finned-tube blocks of charge air coolers of stacked construction are provided with end strips forming a tube bottom. Side surfaces of the end strips adjoining the coolant ducts are configured as exterior surfaces of lips projecting in a direction of the corrugated fins, the tips of these lips not touching the corrugated fins. The end strip cross-section, however, uniformly increases toward the side facing away from the corrugated fins. This further development leads to a considerable reduction of thermal induced tension peaks and therefore contributes to lengthening the useful life of charge air coolers provided with such finned-tube blocks.
