1. An apparatus for cooling integrated circuit chips comprising:
- a housing including a substrate, said substrate having apertures formed therethrough, said housing also including a partition mounted therein defining an inlet chamber and an outlet chamber, said partition having a plurality of openings formed therethrough;
a plurality of heat sinks mounted on said substrate, each heat sink having a first end extending into a respective one of said apertures;
each of said sinks having a second end extending into a respective one of said openings in said partition and having an inlet side of each sink exposed to said inlet chamber and having an outlet side of each sink exposed to said outlet chamber;
a fluid inlet and a fluid outlet in said housing, each inlet side being connected for conducting fluid from said inlet chamber and each outlet side being connected for conducting fluid to said outlet chamber;
each heat sink further having a plurality of elongated spaces formed therethrough for defining a plurality of spaced apart fins for permitting fluid to flow through said heat sink from said inlet side to said outlet side; and
means covering each inlet side for resisting fluid flow between the fins.

Abstract
Apparatus is provided for cooling a closely grouped plurality of integrated circuit chips by forced air convection. A heat sink, having a plurality of fins and a narrow channel between each fin, is connected to a first side of a substrate and has one end protruding into an aperture in the substrate. A chip is connected directly to the one end of the sink and is electrically connected to a second side of the substrate.
