Heat pipe type radiator

Abstract

Abstract PURPOSE:To emit heat generated from a heating element effectively by a method wherein a radiator, provided with a groove having a semi-circular section for fitting the heat pipe on one side of a board therefor and provided projectingly with a plurality of radiating fins vertically on the other side of the board, is utilized. CONSTITUTION:The radiator 6 is worked by extruding so that a plurality of fins 6b are projected vertically on one side of the board 6a while the groove 7, having semi-circular section of a radius R corresponding to the diameter of the heat pipe 3, and pawls 8 are worked on the board 6a simultaneously with the press work of the extruded product. When the heat pipe 3 is arranged into a direction orthogonal to the fins 6b, excellent radiating characteristics due to the convection of air as well as heat transmitting surfaces may be obtained upon the heating of a power transistor 1. According to this method, the number of parts may be decreased remarkably and the cost thereof may be cut down. Further, the heat radiating effect may be increased and the size of the radiator may be miniaturized thereby improving the space factor thereof.
