Abstract

The invention is directed to a method for manufacturing a cylindrical refrigerator housing (2) of a refrigerator cold head composed of a plurality of parts to be connected to one another. To simplify the manufacturing method and reduce the deterioration of the efficiency of the refrigerator due to the application of heat via the refrigerator housing, it is proposed that at least the housing section (1) of the refrigerator housing (2) that encompasses the cylinder wall is manufactured by a cold-working process, for example by ironing, stretching pressure rolling or deep-drawing.
