Abstract
ABSTRACT
A closed fluid cooling system for electronic apparatus includes a plurality of headers interconnected by conduits and also electrical connector assemblies including electrical connectors having couplings to permit the passage therethrough of cooling fluid. The fluid headers are mounted on a printed circuit board and are adapted to receive an electronic substrate for cooling the substrate. The couplings provided in the electrical connectors are arranged to automatically shut off fluid flow any time the electrical connectors are disengaged thereby preventing loss of fluid in the closed fluid cooling system.

Description
The present invention relates to electrical connector assemblies in or for a closed fluid cooling system for electronic apparatus.
According to the present invention, an electrical S connector assembly in or for a closed fluid cooling system for electronic apparatus, comprises first and second releasably matable electrical connectors each including a housing of insulating material, at least one electrical contact mounted in a passageway of the housing and adapted to electrically engage the corresponding electrical contact of the other electrical connector, and a conduit passage in which is mounted a coupling for co-operating engagement with a substantially identical coupling in the other electrical connector when the connectors are mated to permit passage through the mated electrical connectors of a cooling fluid.
An embodiment of the ~nvention will now be descrlbed, by way of example, reference being made to the flgures of the accompanying diagrammatic drawings, in which:-Figure 1 is an exploded perspective view of an electronic systeM having a closed fluid cooling system;
Figures 2, 3 and 4 are details in cross-section of a coupling in various stages from disengagement to engagement, the coupling forming part of the fluid cooling system of Figure 1, Figure 4 being a cross-section on line IV - IV of Figure 1.
: - 2 1052~4 4775 As shown in Flgure 1, an electronic apparatus, for example a portion of a computer, includes a palr of spaced, parallel slde walls 10, 12, a front panel 70, a rear panel (not shown) and a base 22 extending between the side walls. The side walls 10, 12 are formed with grooves 14, 16 dimensioned to receive a plurality of printed circuit boards 18. Supported on the base 22 are a plurality of edge connectors 20, each edge connector being connected to an edge of a printed circuit board 18. At its upper edge (as shown) each board 18 has locking means 24 which secures the board 18 in position in its respective edge connector 20.
Each board 18 carries a plurality of integrated circuit devices which are cooled by a closed fluid cooling system including flu,id headers 26 as descrlbed C,a~ a<cn~
in co-pending~ Applicat~on Seriai No. 237,974 lnterconnected by conduits 36. The first and last headers 26 are connected respectively by conduits 60, 62 to a connector 64 mounted on the board 18 adjacent the edge connector 20. The connector 64 is adapted to make both electrical and fluid tight connection with the edge connector 20.
A fluid and electrical distribution cable 66 : connects individual connectors 20 to a connector 68 mounted on the panel 70. The connector 68 is similarly connected to a main fluid cooling system by a fluid and electrical distribution cable 72.

lOSZ004 At each of the interconnect posltions in the fluid cooling system, namely, between the connectors 20 and 64 and in the mating halves of the connector 68, each fluld line is provided with a coupling 74 shown in detail in Figures 2 to 4 in association with the connectors 20 and 64. Each coupling 74 comprises means in the form of a fitting 76 one end of which engages the appropriate associated conduit (not shown). The other end of fitting 76 is joined to a body 78 by annular ridges 80. The body 78 has an axial bore which communicates with a narrow opening 82 at the opposite end from fitting 76. A resilient sealing member 84 is mounted in the narrow opening 82 and has an annular flange 86 inside the body and an enlarged profiled head 88 outside the body. The sealing member 84 also has an axial bore 90 coaxial with the bore in the body 78 which bore 90 communicates with a shallow conical entrance 92. A valve member 94 is mounted in the body 78 with lntegral stem 96 extending from a head 98 and passing through the bore 90. The head 98 of the valve member 94 is blased against the flange 86 of sealing member 84 by a spring 100. A stop 102 projects from the head 98 of the valve member 94 in the opposite direction from the stem 96. The end of the spring 100 opposite that which engages the head 98 abuts against an end of the fitting 76.
The coupllngs 74 assoclated w1th the connectors lOSZ004 20 and 64 are identical. The coupling 74 on the left of Figures 2 to 4 has been mounted on the connector 64 as a plug member projecting from the connector 64, while the coupling 74 on the right is recessed as a receptacle ln its associated connector 20. The same conditions would apply for the mating halves of connector 68.
The steps of engaging the couplings 74 are shown ln Figures 2 to 4. Figure 2 shows the separated or fully disconnected position of the couplings. In this position the heads 98 of both valve members 94 are biased against flanges 86 of sealing members 84 by springs 100 to prevent fluid flow through the couplings. When the couplings are initially engaged, as shown in Figure 3, the free ends of the sealing members 84 engage and are compressed against each other to form a leak proof passageway through the aligned axial bores 90. As the relative movement of the couplings towards one another continues, the free ends of the valve stems 96 engage and begin to open the valve members 94 against the 2Q biasing force of springs 100 to establish fluid flow therethrough. The stops 102 on the end of each valve member 94 eliminate the possibility of only one valve member opening while the other valve member stays closed. If one valve member sticks in the closed position the stop 102 of the other valve member will abut its related fitting 76 so that all the force bringlng the couplings together will be applied against the stuck , _ 5 _ valve member.
Full fluid communication between the mated couplings 74 is shown in Figure 4. Dlsengagement of the couplings 74 produces a reverse actlon to that described above. As the valve members 94 are closed by springs 100 the sealing members 84 expand preventing undue leakage of the fluid from the system. ' The connectors 20, 64 are releasably matable together and are latched in the mating position by latching means (not shown).
Each connector 20, 64 has a plurality of passageways ~n each of which is mounted an electrical contact (not shown) for electrically engaging co-operating electrical contact of the mating connector.
According to the present invention, an electrical S connector assembly in or for a closed fluid cooling system for electronic apparatus, comprises first and second releasably matable electrical connectors each including a housing of insulating material, at least one electrical contact mounted in a passageway of the housing and adapted to electrically engage the corresponding electrical contact of the other electrical connector, and a conduit passage in which is mounted a coupling for co-operating engagement with a substantially identical coupling in the other electrical connector when the connectors are mated to permit passage through the mated electrical connectors of a cooling fluid.
An embodiment of the ~nvention will now be descrlbed, by way of example, reference being made to the flgures of the accompanying diagrammatic drawings, in which:-Figure 1 is an exploded perspective view of an electronic systeM having a closed fluid cooling system;
Figures 2, 3 and 4 are details in cross-section of a coupling in various stages from disengagement to engagement, the coupling forming part of the fluid cooling system of Figure 1, Figure 4 being a cross-section on line IV - IV of Figure 1.
