Abstract
Abstract An arrangement of a plurality of microcooling devices provided with electrical components, each microcooling device having a closed channel structure for a coolant to flow through, and being provided with electrical conductors for the electronic components and with externally carried fluid ducts for a coolant which flows through the channel structures. A covering layer which forms one of at least two flat sides of the microcooling device is made from an electrically insulating material with good heat conductivity. The electronic components are arrayed on this cover layer and on the opposite flat side of each microcooling device. Adjacent microcooling devices which are provided with electronic components on confronting flat sides are arranged with their components spaced apart or staggered with respect to one another, and the components of one microcooling device preferably are in contact with the cover layer of the adjacent microcooling device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
148 words
A microcooling arrangement comprising a plurality of adjacent microcooling devices each provided with at least one electronic component, each microcooling device having two opposed flat sides and comprising a closed channel structure through which a coolant passes, outwardly extending fluid lines for respectively supplying and carrying away the coolant flowing through the channel structures, outwardly extending electrical conductors for the electronic components, and a cover layer which forms one of the flat sides made of a heat-conducting, electrically-insulating material; wherein: the at least one electronic component is arranged on one of the opposed flat sides of each microcooling device; adjacent microcooling devices are spaced apart from one another with proximate flat sides, which have at least one electronic component arranged thereon, confronting one another, and at least one of said electronic components on one microcooling device lies in contact with the cover layer of an adjacent microcooling device.
Claim 2
Dependent Claim
