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 9 Each figure in each figure is shown for alternative methods for coating the adhesive layer 1 to the heat exchanger assembly 2 (heat exchanger) to be coated, wherein regardless of the various method steps of the alternative method. How, the adhesive layer 1 is applied to the outside of the assembly 2 in each case.

[0029] consider figure 1The method shown is designed as a narrow blank 3, and the adhesive layer 1 is designed as an adhesive film 4. Here, both the adhesive film 4 and the assembly 2 designed to be narrow blanks 3 are rolled up, i.e., one volume on the adhesive film volume 5, and the other on the narrow blank volume 6. Then, in the first method step, oil removal and brushing of the surface of the narrow blank 3 to be applied with the adhesive layer 1 is performed, which is carried out in the cleaning unit 7. In this case, for example, oil removal and brushing can be carried out by plasma or corona discharge or the like. Then, the adhesive fil...

Abstract

The invention relates to a method for producing a heat exchanger having at least two components (2, 11) bonded together. It is essential for the invention that at least one of the components (2, 11) is coated with an adhesive layer (1).

Description

Technical field [0001] The present invention relates to a method of manufacturing a heat exchanger having at least two components having a bonded to each other according to claim 1. Background technique [0002] The cooling module used for the use of the refrigerant and the use of coolant has been produced for decades, and it is usually involved in materials suitable for brazing, such as stainless steel, copper or aluminum. These materials are coated with brazing alloys as semi-finished products. The brazing alloy plating on the semi-finished product includes a layer of material having a low melting point than the base material. In order to braze, the components are clamped, and then solder at a temperature close to the melting point of the base material in the furnace. The required necessities required for this purpose include, for example, a flux for breaking or dissolving the outer oxide layer. However, the flux has a disadvantage of harmful health; in addition, the residue ma...
