Method of making a pin fin heat exchanger

摘要

A pin fin heat exchanger is made by wrapping a thermally conductive wire having a coating thereon around a mandrel thereby forming a multilayer coil. The coating is fused together for holding the wires together. The method includes cutting a section out of the coil providing a plurality of generally parallel wires having first and second ends and placing the cut section between an object and a wall for transferring heat therebetween with the first ends engaging the object and the second ends engaging the wall. Thereafter the coating is removed from the wires such as by solvents. The ends of the wires may be soldered or may be lapped to provide a convex surface to provide good heat transfer.
