Abstract

A cooling apparatus for a circuit module having a substrate extending axially with an IC chip of a first type and IC chips of a second type mounted thereon, comprising: a first heat spreading element disposed to form a heat conduction path with the IC chip of the first type; and a second heat spreading element disposed to form a heat conduction path with the IC chips of the second type, wherein there is at least one IC chip of the second type mounted axially away from opposite sides of the IC chip of the first type, wherein the first type of IC chip is capable of generating a larger amount of heat than the second type of IC chips, and the first heat spreading element has a higher thermal conductivity than the second heat spreading element.
