Abstract

A liquid-cooling assembly includes two or more cooling sub-assemblies and a flexible interconnect assembly. The two or more cooling sub-assemblies are configured for cooling two or more respective pluggable connector-cages, each cooling sub-assembly including (i) a heat-conducting plate for coupling to a respective pluggable connector-cage, and (ii) a liquid-conducting channel having an inlet and an outlet for flowing cooling liquid. The flexible interconnect assembly is configured to transfer the cooling liquid to and from inlets and outlets of the cooling sub-assemblies, and to mechanically support the cooling sub-assemblies while permitting motion of the cooling sub-assemblies relative to one another.

First claim

The invention claimed is:

1. A liquid-cooled connector assembly, comprising:
two or more sockets, which are mounted side-by-side and are configured to receive two or more respective plugs, the sockets comprising electronic components that generate heat;
two or more cooling sub-assemblies for evacuating at least some of the heat from the two or more respective sockets, each cooling sub-assembly comprising (i) a heat-conducting plate for coupling to a respective socket, and (ii) a liquid-conducting channel having an inlet and an outlet for flowing cooling liquid, thereby cooling the heat-conducting plate; and
a flexible dual-purpose interconnect assembly, which is configured to both (i) transfer the cooling liquid to and from inlets and outlets of the cooling sub-assemblies, and (ii) mechanically support the cooling sub-assemblies while permitting motion of the side-by-side mounted sockets relative to one another.

2. The liquid-cooled connector assembly according to claim 1 , wherein the flexible dual-purpose interconnect assembly is configured to transfer the cooling liquid in series between the inlets and the outlets of the two or more cooling sub-assemblies.

3. The liquid-cooled connector assembly according to claim 1 , wherein the flexible dual-purpose interconnect assembly comprises tubes that are configured to transfer the cooling liquid and are interwoven with each other.

4. The liquid-cooled connector assembly according to claim 3 , wherein the flexible dual-purpose interconnect assembly permits vertical motion of the side-by-side mounted sockets relative to one another by the tubes being interwoven with each other.

5. The liquid-cooled connector assembly according to claim 1 , wherein the flexible dual-purpose interconnect assembly comprises soft interconnecting hoses configured to transfer the cooling liquid.

6. The liquid-cooled connector assembly according to claim 1 , wherein the flexible dual-purpose interconnect assembly permits vertical motion of the side-by-side mounted sockets relative to one another.

7. The liquid-cooled connector assembly according to claim 1 , wherein the flexible dual-purpose interconnect assembly is configured to prevent vertical motion caused by plugging or unplugging a cable into one of the sockets from affecting another of the sockets.

8. The liquid-cooled connector assembly according to claim 1 , wherein the flexible dual-purpose interconnect assembly and the two or more cooling sub-assemblies are attached to one another with screws.

9. A manufacturing method, comprising:
attaching to two or more sockets two or more respective cooling sub-assemblies for evacuating at least some of the heat from the two or more respective sockets, each cooling sub-assembly comprising (i) a heat-conducting plate for coupling to a respective socket, and (ii) a liquid-conducting channel having an inlet and an outlet for flowing cooling liquid, thereby cooling the heat-conducting plate; and
coupling to the two or more cooling sub-assemblies a flexible dual-purpose interconnect assembly, which is configured to both (i) transfer the cooling liquid to and from inlets and outlets of the cooling sub-assemblies, and (ii) mechanically support the cooling sub-assemblies while permitting motion of the side-by-side mounted sockets relative to one another.

10. The manufacturing method according to claim 9 , wherein cooling the sockets comprises transferring the cooling liquid in series between the inlets and the outlets of the two or more cooling sub-assemblies.

11. The manufacturing method according to claim 9 , wherein coupling the flexible dual-purpose interconnect assembly comprises coupling tubes that are interwoven with each other.

12. The manufacturing method according to claim 11 , wherein permitting vertical motion of the cooling sub-assemblies relative to one another by the flexible dual-purpose interconnect assembly comprises inter-weaving the tubes of the flexible interconnect assembly with each other.

13. The manufacturing method according to claim 9 , wherein coupling the flexible dual-purpose interconnect assembly comprises coupling soft interconnecting hoses.

14. The manufacturing method according to claim 9 , wherein coupling the flexible dual-purpose interconnect assembly comprises attaching the flexible dual-purpose interconnect assembly and the two or more cooling sub-assemblies to one another using screws.
