ABSTRACT:
In order to be able to use materials of higher strength without the danger of cracks arising during deformation, it is proposed, with reference to a heat exchanger having lamella fins, which are held at a distance from and parallel to each other by shaped collars on the lamella fins and which are penetrated by pipes running parallel to each other in passages through the collars, the internal diameter of the passage in each case matching the external diameter of the pipe and at least partially contacting the external periphery of the pipe, while at the same time exactly preserving the distances between the lamella fins, that tongues are distributed on the periphery of the punched rim of the passage, the free ends of the tongues are bent at an angle to the pipe projecting through the passage, and that these bent tongues provide space locating surfaces for the adjacent parallel lamella fin. Also disclosed is a heat exchanger assembly.
