Power supply cooling module

Abstract

Abstract PURPOSE:To ease mounting and enhance cooling effect by constructing a heat sink with an upper heat sink brought into close contact with a case upper surface of a power supply and having a through-hole for a fixed machine screw at the side edge thereof, and with a lower heat sink brought into close contact with both side walls of the case and having a screw hole in the upper surface, and fixing a screw hole in the upper surface, and fixing the heat sink via a flange part of the case upper surface. CONSTITUTION:For mounting a heat sink 2 on a power supply 1 mounted on a printed board 6 a lower heat sink 4 is placed on the printed board 6 along opposite side walls 13 of a case 11 of the power supply 1. Then, an upper heat sink 3 is brought into contact with the upper surface of the case 11, and a through-hole 32, a notched hole part 14 in a flange part 12, and a screw hole 42 in the lower heat radiator 4 are positioned. By inserting a fixing screw 5 into the hole and clamping it, the upper and lower heat sinks 3 and 4 are fixed to the case 11 in close contact with each other holding the flange part 12 of the case 11 therebetween. Accordingly, a power supply cooling module can be formed by the work from the upper part in the state where the lower heat sink to 4 is placed.
