摘要

The radiator has a corrugated sheet (1), where both flanks of the corrugation are welded with each other in an upper side and a lower side in an impermeable manner. A bearing sheet (2) is folded at its upper ends and lower ends such that collectors (3, 4) are formed from the folded regions. The corrugated sheet is welded to the bearing sheet in an impermeable manner. The collectors are closed at one side in an impermeable manner, and provided with a flange (5) at an oppositely lying other side.
