Title: METHOD FOR PRODUCING A HEAT EXCHANGER AND HEAT EXCHANGER
Abstract:
The present invention relates to a method for producing a heat exchanger (1) with tubes (2) which are fixed on the longitudinal end sides in associated openings (3) of a tube plate (4) of a collector (5). According to the invention: a) an adhesive layer (6) is applied to an outer side of the tubes (2) by laminating an adhesive sheet (7) or an adhesive film (8), b) the tubes (2) are inserted into a respectively associated opening (3) on the tube plate (4) by a longitudinal end side tube wall section (9), wherein the tube wall sections (9) of the tubes (2) are bent in such a way that they contact non-parallel walls (10) of the associated opening (3), c) the adhesive layer (6) is heated for adhering the tube wall sections (9) to the walls (10) of the openings (3). The invention further relates to a heat exchanger (1) produced using a method of this type.
