Abstract

PURPOSE: To provide the heat exchange pipe that has a high performance and can be manufactured efficiently and simply, by supporting the bottom part of a U-shaped needle fins group, being composed of fine gauge wires, by means of a large gauge wire for core bar, and by winding in such a manner that the U-shaped base part shall contact an external surface of a pipe.
