Abstract:
A coolant for cooling a semiconductor element by direct immersion cooling, used at a temperature in a range of room temperature to 80.degree. C., consisting of a low boiling point fluorocarbon and a high boiling point fluorocarbon, the low boiling point fluorocarbon having a boiling point of 30.degree. C. to 100.degree. C. and the high boiling point fluorocarbon having a boiling point higher than that of the low boiling point fluorocarbon by at least 100.degree. C., an amount of the high boiling point fluorocarbon being from 1.5% by volume to 20% by volume based on the volume of the low boiling point fluorocarbon, wherein the high boiling point fluorocarbon is selected from the group consisting of tris (perfluorohexyl) amine, tris (perfluoropentyl) amine, and ##STR3##
