Problems solved by technology

[0004] As an alternative to brazing, there is also the purely theoretical possibility of bonding the individual components of the heat exchanger, but this has so far failed due to the lack of methods with suitable process reliability
Furthermore, it is not possible to construct a bubble-free and high-quality coating of an adhesive layer with a correspondingly sufficient flexibility in a reliable process so that it can be easily adapted to different requirements

Embodiment Construction

[0028] exist Figure 1 to Figure 9 In each of the Figures there is shown an alternative method for applying the adhesive layer 1 to the heat exchanger assembly 2 to be coated (heat exchanger not shown), wherein, regardless of the individual method steps of the alternative method In any case, the adhesive layer 1 is applied to the outside of the component 2 in each case.

[0029] consider figure 1With the method shown, the component 2 to be coated is designed as a narrow blank 3 and the adhesive layer 1 as an adhesive film 4 . Both the adhesive film 4 and the component 2 designed as a narrow blank 3 are rolled up here, ie one on an adhesive film roll 5 and the other on a narrow blank roll 6 . Then, in a first method step, degreasing and brushing of the surface of the narrow blank 3 to be coated with the adhesive layer 1 takes place, which takes place in the cleaning unit 7 . In this case, for example, degreasing and brushing can be performed by plasma or corona discharge or ...

Abstract

The invention relates to a method for producing a heat exchanger having at least two components (2, 11) which are adhered together. It is essential to the invention that, on an outer side, at least one of the components (2, 11) is applied to the adhesive layer (1).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for the manufacture of a heat exchanger having at least two components bonded to each other. Background technique [0002] Cooling modules for the use of refrigerants and for the use of coolants have been produced for decades, usually involving materials suitable for brazing, such as stainless steel, copper or aluminium. These materials are coated with brazing alloys as semi-finished products. The brazing alloy coating on the semi-finished product comprises a layer of material having a lower melting point than the base material. For brazing, the components are clamped and then brazed in a furnace at a temperature close to the melting point of the base material. Necessities required for this purpose include, for example, fluxes that break open or dissolve the outer oxide layer. However, fluxing agents have the disadvantage of being harmful to health; moreover, residues may remain ...
