Title:

COOLING DEVICE FOR ELECTRIC HEATING ELEMENT

Document Type and Number:

Japanese Patent JPH01192149

Kind Code:

A

Abstract:

PURPOSE: To prevent a potential from being applied to a heat sink by a method wherein a high-heat conductivity electric insulator is arranged between an electric heating element and the heat sink.

CONSTITUTION: A high-heat conductivity electric insulator 5 is formed by a method wherein a resin-impregnated prepreg sheet is laminated on a ceramic paper, for example, and the laminated matter is cured by heating. The insulator 5 transmits heat generated from a semiconductor element 1 to a heat-receiving part 2a of a heat sink 2 and at the same time, does not transmit the potential of the element 1 to the sink 2 and insulates electrically the sink 2 from the element 1. A current to be made to flow through the element 1 is led out to the exterior through a terminal 4. Moreover, the sink 2 is insulated electrically from the element 1 and the terminal 4 by the insulator 5 and no potential is applied to the heat sink.
