PURPOSE: To fabricate a radiator of easy manufacture and of easy assembly which is best suited for application to heating elements of lower power by a construction wherein a heat pipe is placed in close contact with inside of the best bottom of a fin of sheet metal which has been bent into a U-shape. A mount for a heating element is provided on either the fin or the heat pipe.
CONSTITUTION: The heat pipe 1 is placed horizontally inside the bent bottom 6 of a fin 5 of an aluminum or a copper sheet which has been bent into a U- shape with part of the external surface of the heat pipe in close contact with the inside surface of the fin. In addition to the mount for the heating element 7 provided on the side of the fin 5, U-cuts 8 are made on both sides of the fin to be pressed down inside against the surface of the heat pipe 1 for retention. The openings resulting from the U-cuts serve concurrently as air vents 9. This construction allows efficient radiation of heat generated from an element 2 which is mounted on the mount for heating element 7 by means of both the fin 5 and the heat pipe 1. Moreover, a plural number of cuts are made at the ends of the fin 5 to bend the resultant tongues alternately inward and outward to form branched ends 10 whereby not only the fin 5 can be made to be smaller in size but also other various alternations can be made.
