Abstract
Abstract The invention concerns a heat exchanger panel for evaporator or condensor in a refrigerator. The panel comprises a plate (2) with several parallel running grooves (21) with converging walls (22) for locking of heat transporting pipes (3). The invention furthermore concerns a method for manufacturing the heat exchanger panel comprising extruding of profiled plates (2) with grooves (21), placing of individual or connected pipes (3) in the grooves (21) and exposing of the pipes (3) to plastic deformation so that their circumference conforms to and fills out the cavity of the groove (21).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
Heat exchanger panel comprising a profiled heat absorbing or heat emitting plate (2) and a heat transporting system of pipes (3) attached to the plate, where the said plate (2) comprises several parallel running grooves (21), characterized in that the grooves (21) ara designed with half-closed, oval cross-section with the largest diameter of the groove (21) larger than the diameter of the pipes (3) and with the walls of the groove (22) converging towards the open end (23) and locking the pipes which are introduced into the grooves (21) and subsequently exposed to plastic deformation so that they fill the cavity of the groove.
Claim 2
Dependent Claim
104 words
Heat exchanger panel comprising a profiled heat absorbing or heat emitting plate (2) and a heat transporting system of pipes (3) attached to the plate, where the said plate (2) comprises several parallel running grooves (21), characterized in that the grooves (21) ara designed with half-closed, oval cross-section with the largest diameter of the groove (21) larger than the diameter of the pipes (3) and with the walls of the groove (22) converging towards the open end (23) and locking the pipes which are introduced into the grooves (21) and subsequently exposed to plastic deformation so that they fill the cavity of the groove.
Claim 3
Dependent Claim
36 words
Heat exchanger panel according to claim 1, characterized in t'h a t the free part of the pipes (3) is flattened and practically on a level with the converging side walls (22) in the groove (21).
Claim 4
Dependent Claim
125 words
Procedure for manufacturing of heat exchanger panel in a cooling or heating system according to claim 1 or 2, characterized in a combination of the following process stages: - extruding of a profiled plate (2) comprising a several substantially parallel running grooves (21) with half-closed oval cross-section with the largest diameter of the groove larger than the diameter of the heat transporting pipe (3) in the system, - embedding of individual or connected pipes (3) in the grooves (21), and - subsequent transfer of the plate with embedded pipes to a device for causing plastic deformation to the pipes so that their circumference conforms to and fills out the cavity of the groove, and the pipes are locked into the grooves under converging walls (22).
Claim 5
Dependent Claim
18 words
Method according to claim 3, characterized in that plastic deformation of pipes is caused by a press operation.
Claim 6
Dependent Claim
20 words
Method according to claim 3, characterized in that plastic deformation is made by rolling of the pipes in the grooves.
