Abstract

PURPOSE: To make possible improvement of heat transfer performance and light and small design by such a construction that a heat transfer tube is molded in a zigzag line, the tube ends are exposed to that peripheral zone, and porous metal is fixed by solid molding.
CONSTITUTION: A die is formed by draughty plastics having continuous cavities such as foamed uletane, and after filling these cavities with fluid casting material, a heat transfer tube 1 molded in a zigzag line is buried in with its ends exposed. Then the casting material is hardened by such a process as a heating as well as the die plastic is reduced to disapperance by a process such as gasifying to mold the die cavities. After molding the die cavities, the inside of the cavities shall be depressurized and filled with fusion metal by suction, and after the fusion metal is solidified the die will be removed. By this method a fin block 2 of porous metal having continuous cavities in the apperance of a skelton composed of thin-wired fins 3 is fixed around the heat transfer tube 1 formed in a zigzag line to make possible a light and small-sized design.
