(54)	Method for producing a heat exchanger for a refrigeration apparatus and heat exchanger produced therewith

(57) The invention relates to a method for producing a heat exchanger for household-type and similar refrigeration appliances, said heat exchanger being manufactured starting from a coil-like bent pipe (10) and at least a plate (51), wherein said pipe and said plate are preferably made of an iron alloy. Along at least one (15) of the substantially rectilinear sections (21) of the coil, the pipe (10) is torsionally deformed beyond the limit of elasticity of the material of which it is made. The therewith associated plate (51) is at the same time bent at right angle. The invention also relates to a heat exchanger produced according to such a method.
