Cooler for semiconductor rectifier

Abstract

Abstract PURPOSE:To cool many semiconductor elements with a set of coolers and to enable to form the entirety in small size by aligning a plurality of heat sink blocks laterally and flexibly coupling a heat sink tube inserted from the end block side between the blocks. CONSTITUTION:Numerals 1, 1' designate semiconductor rectifiers in the drawing, heat sink blocks 2, 2' contacted with the upper and lower sides of the rectifiers 1, 1' are aligned laterally in parallel with each other, a heat sink tube 3 forming a heat pipe is inserted from the sides of the blocks 2, 2', and the ends 3a of the tube 3 disposed between the blocks 2 and 2' are coupled with bellows 5. In this case, the tube 3 is partly opened in the block 2, part of the heat pipe may be formed at the block 2 itself. A fin 4a forming a heat sink 4 is mounted on the surface of the projection of the tube 3 in the same manner as the conventional one.
