Abstract
Abstract A heavy duty cooling system utilizes air as a cooling fluid, the air being supplied at a suitable pressure in a main pipe which opens into a number of secondary pipes. Each secondary pipe terminates in a calibrated orifice which supplies a predetermined air flow to a component to be cooled. In the case where the components are arranged in groups, a secondary pipe opens through a calibrated conduit into a plenum chamber which distributes the air through calibrated openings formed in one of its walls to each of the components of the group. In order to increase the heat exchange, the area to be cooled is separated from the discharge opening by an expansion chamber into which the jet of fluid is directed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
128 words
In combination, a multiplicty of heat-generating electronic components, arrayed in a plurality of groups, and a cooling system for dissipating the generated heat, said cooling system comprising: a heat exchanger provided with an inlet and an outlet for a gaseous fluid, blower means for driving said fluid, and cooling means for said fluid between said inlet and said outlet; a supply manifold connected to said outlet for receiving said fluid therefrom; a plurality of branch conduits extending from said supply manifold; and a separate plenum chamber connected to each of said branch conduits and juxtaposed with a respective group of said components, each plenum chamber being provided with a multiplicity of calibrated discharge openings individually confronting the components of said group for training a cooling flow upon same.
Claim 2
Dependent Claim
128 words
In combination, a multiplicty of heat-generating electronic components, arrayed in a plurality of groups, and a cooling system for dissipating the generated heat, said cooling system comprising: a heat exchanger provided with an inlet and an outlet for a gaseous fluid, blower means for driving said fluid, and cooling means for said fluid between said inlet and said outlet; a supply manifold connected to said outlet for receiving said fluid therefrom; a plurality of branch conduits extending from said supply manifold; and a separate plenum chamber connected to each of said branch conduits and juxtaposed with a respective group of said components, each plenum chamber being provided with a multiplicity of calibrated discharge openings individually confronting the components of said group for training a cooling flow upon same.
Claim 3
Dependent Claim
11 words
The combination defined in claim 1 wherein said fluid is air.
Claim 4
Dependent Claim
24 words
The combination defined in claim 1 wherein said heat exchanger includes an external cross-flow fan for transferring heat from said fluid to ambient air.
Claim 5
Dependent Claim
29 words
The combination defined in claim 1, further comprising an enclosure surrounding said group of components and said plenum chamber, said enclosure being provided with an exit for spent fluid.
Claim 6
Dependent Claim
18 words
The combination defined in claim 4, further comprising a return conduit extending from said exit to said inlet.
Claim 7
Dependent Claim
15 words
The combination defined in claim 1 wherein said branch conduits are provided with calibrated constrictions.
Claim 8
Dependent Claim
55 words
The combination defined in claim 1 wherein said group of components are provided with a common support, further comprising a plurality of receptacles of thermally conductive material communicating with respective discharge openings of said plenum chamber, said receptacles having end walls in contact with said support and interposed between said discharge openings and confronting components.
Claim 9
Dependent Claim
31 words
The combination defined in claim 7 wherein the interiors of said receptacles are substantially wider than said discharge openings, thereby enabling said fluid to spread along the inner wall surfaces thereof.
Claim 10
Dependent Claim
36 words
The combination defined in claim 8 wherein said receptacles are generally cup-shaped with open ends opposite said end walls, said discharge openings being formed by nozzles spacedly extending through said open ends toward said end walls.
Claim 11
Dependent Claim
35 words
The combination defined in claim 8 wherein said receptacles are substantially cylindrical with partly closed ends opposite said end walls formed with said discharge openings and with lateral ports for the escape of spent fluid.
Claim 12
Dependent Claim
19 words
The combination defined in claim 10 wherein said receptacles project into said plenum chamber at said partly closed ends.
Claim 13
Dependent Claim
21 words
The combination defined in claim 11, further comprising insulating seal means supporting said receptacles in a wall of said plenum chamber.
Claim 14
Dependent Claim
27 words
The combination defined in claim 7 wherein said support is a ceramic plate, said components being diodes carried in apertures of said plate overlying said end walls.
