Attaching fin material to a heat transfer or like surface

摘要

A heat transfer or like surface has fins attached thereto in a disconnected, spaced apart, substantially parallel relation, the fins standing upright on edge on the surface. A method of producing and attaching the fins has particular utility in the presence of a curved mounting surface, the fins being formed to allow them to be bent in conformance with the curved surface. Apparatus including an adjustable roller mechanism and a braze fixture are useful in forming and attaching the fin material.
