摘要:
A heat exchanging member (1), more particularly for cooling a semiconductor module, having at a first and a second side, respectively, inlets and outlets, respectively, for a preferably gaseous heat exchanging medium, and having a heat exchanging component (2) made of a highly thermal conductive material, such as metal, in which channels disposed side by side and running from its inlet side to its outlet side have been formed, such that medium flowing in through the inlet channels is constrained to flow at an angle to the direction of entry via the heat exchanging material to the adjacent outlet channels, characterized in that the heat exchanging material has a structure which
a) is composed of randomly packed elementary parts, such as grains, fibres or scales, or b) is composed of parts packed in an ordered fashion, such as gauze or plates, with the exception of individual wires.
In a preferred embodiment the heat exchanging material is made up of sintering bronze.
摘要:
Multichip module with provisions for improved cooling and interconnection so as to allow for maximum chip packaging density. Air cooling is brought about by a zig-zag arrangement of groups (6) of thin wire cooling fins (5) mounted on a heat sink layer (3) also providing the necessary mechanical rigidity of the module. Said interconnection means comprises a layer (22) containing diamond grains (23) having high electrical insulating and high thermal conductive properties.
