COOLING OBJECTS, FOR EXAMPLE SEMICONDUCTOR DEVICES

摘要

A heat transfer medium having a composition such that it is in the form of a phase mixture of solid and liquid phases at the appropriate temperature. The phases may be a solid solution and a liquid mixture of two or more components, providing the medium as a metal sherbet. For instance, in an In-Ga binary system solids of In-Ga solid solution are dispersed in an In and Ga liquid. The medium (4) may be placed between a cooling unit (6) and an object, e.g. a semiconductor device (2), to be cooled, exhibiting the solid and liquid phase mixture form at the normal operating temperature of the device and cooling unit.
