Abstract
Abstract Heat exchanger panel and process of making such panel comprised of selectively clad or bonded metal plates made of a material which cannot be cold roll bonded without great difficulty, if at all, with at least one channel disposed therebetween. An adhesive layer of an amorphous metal is provided between the plates for permanently joining the plates together by cold roll bonding in the area of the adhesive layer.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
104 words
Heat exchange panel comprised of two selectively clad metal plates and at least one channel disposed between these plates for a liquid or gaseous medium flowing therein to be warmed or cooled, wherein the plates are made of a material which can be cold roll bonded only with difficulty or not at all when using conventional cladding processes, and an adhesive layer made of an amorphous metal is provided between the two plates and on both sides of and in proximity to said at least one channel, the plates being permanently joined together by cold roll bonding in the area of the adhesive layer.
Claim 2
Dependent Claim

Claim 15
Dependent Claim
26 words
Process according to claim 12, including the further step of bonding a cover layer on each metal strip before cold roll bonding together the metal strips.
Claim 16
Dependent Claim
14 words
Process according to claim 12, wherein the adhesive layer is an amorphous metal foil.
Claim 17
Dependent Claim
25 words
Process according to claim 12, including the step of applying the adhesive layer as a surface layer to at least one of the metal strips.
