FIELD: electricity.
SUBSTANCE: unit of heat sink fixation comprises stop, screw and pusher, besides stop has such shape that as screw moves, pusher presses heat sink identically to 2 coupled surfaces: body and heat-loaded element. There are holes provided in body and heat sink. Proposed structure makes it possible to efficiently remove heat to body of instrument and avoid using fan, which is traditionally used for the purposes of radio-electronic instrument cooling.
EFFECT: more efficient removal of heat from heat-loaded elements due to combination of conductive and convective heat transfer methods in device, preservation of device design integrity for heat removal in process of assembly and disassembly, increased density of radio elements of assembly.
