Abstract

A cabinet liquid cooling system is configured to dissipate heat of a cabinet. A flow allocation unit is installed on a single side of the cabinet, is located in space between a side wall of the cabinet and a mounting bar of the cabinet, and is provided with a liquid inlet and a liquid outlet. A liquid cooling system (LCS) control unit is installed at the bottom of the cabinet and cyclically supplies liquid to the flow allocation unit using the liquid inlet and the liquid outlet. A liquid supply branch includes a liquid delivery pipe and a liquid return pipe. A node pipe includes a liquid inlet pipe and a liquid outlet pipe. Both the liquid inlet pipe and the liquid outlet pipe are connected to the corresponding liquid delivery pipe and liquid return pipe using the quick male connector and the quick female connector.

First claim

What is claimed is:

1. A cabinet liquid cooling system configured to dissipate heat of a cabinet, the cabinet liquid cooling system comprising:
a flow allocator installed on a side wall of the cabinet and that is located in space between the side wall of the cabinet and a mounting bar of the cabinet, the flow allocator being provided with a liquid inlet and a liquid outlet, the liquid inlet, being coupled to a liquid inlet unit of the flow allocator, and the liquid outlet being coupled to a liquid outlet unit of the flow allocator;
multiple liquid supply branches in a one-to-one correspondence to multiple mounted electronic devices, each of the liquid supply branches passing proximate to one of the mounted electronic devices, each of the liquid supply branches comprising a liquid delivery pipe and a liquid retum pipe that communicate with the flow allocator individually, and each of the liquid delivery pipes having a length that is less than a length of each of the liquid return pipes;
multiple pairs of quick female connectors and quick male connectors that cooperate with each other;
multiple node pipes in a one-to-one correspondence to the multiple liquid supply branches, each of the node pipes comprising a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe of each of the node pipes being coupled to the liquid delivery pipe of the corresponding liquid supply branch using one of the pairs of quick female connectors and quick male connectors, and liquid outlet pipe of each of the node pipes being coupled to the liquid return pipe of the corresponding liquid supply branch using the one of the pairs of quick female connectors and quick male connectors;
a mounting bracket that supports the multiple node pipes, the liquid inlet unit of the flow allocator being positioned between the mounting bracket and the liquid outlet unit of the flow allocator; and
a liquid that is configured to enter the liquid inlet unit of the flow allocator through the liquid inlet, pass through one of the liquid delivery pipes to one of the node pipes, pass through the one of the node pipes to one of the liquid return pipes and then to the liquid outlet unit of the flow allocator, and exit the liquid outlet unit of the flow allocator through the liquid outlet.

2. The cabinet liquid cooling system of claim 1 , wherein one end of either of the liquid delivery pipe and the liquid return pipe is coupled to the quick female connector, and the other end is coupled to the flow allocator.

3. The cabinet liquid cooling system of claim 1 , wherein the liquid delivery pipe, the liquid return pipe, the liquid inlet pipe, and the liquid outlet pipe are all hoses.

4. The cabinet liquid cooling system of claim 1 , wherein each of the mounted electronic devices is provided with a closed pipeline circulation system for the liquid to flow.

5. The cabinet liquid cooling system of claim 1 , wherein the liquid inlet unit of the flow allocator and the liquid outlet unit of the flow allocator are parallel to each other.

6. The cabinet liquid cooling system of claim 1 , wherein the liquid inlet unit of the flow allocator and the liquid outlet unit of the flow allocator are perpendicular to all of the liquid delivery pipes and all of the liquid return pipes.

7. The cabinet liquid cooling system of claim 1 , wherein all of the pairs of quick female connectors and quick male connectors fall within a straight line that is parallel to the flow allocator.

8. The cabinet liquid cooling system of claim 1 , wherein the liquid comprises water.

9. The cabinet liquid cooling system of claim 1 , wherein the liquid comprises oil.

10. The cabinet liquid cooling system of claim 1 , wherein the liquid comprises a mixture.

11. A cabinet comprising multiple mounted electronic devices disposed in the cabinet, the cabinet having a cabinet liquid cooling system, the cabinet liquid cooling system supplying liquid for heat dissipation to the multiple electronic devices, and the cabinet liquid cooling system comprising:
a flow allocator installed on a side wall of the cabinet and that is located in space between the side wall of the cabinet and a mounting bar of the cabinet, the flow allocator being provided with a liquid inlet and a liquid outlet, the liquid inlet being coupled to a liquid inlet unit of the flow allocator, and the liquid outlet being coupled to a liquid outlet unit of the flow allocator;
multiple liquid supply branches in a one-to-one correspondence to the multiple mounted electronic devices, each of the liquid supply branches comprising a liquid delivery pipe and a liquid return pipe that communicate with the flow allocator individually, and each of the liquid delivery pipes having a length that is less than a length of each of the liquid return pipes;
multiple pairs of quick female connectors and quick male connectors that cooperate with each other;
multiple node pipes in a one-to-one correspondence to the multiple liquid supply branches, each of the node pipes comprising a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe of each of the node pipes being coupled to the liquid delivery pipe of the corresponding liquid supply branch using one of the pairs of quick female connectors and quick male connectors, and the liquid outlet pipe of each of the node pipes being coupled to the Liquid return pipe of the corresponding liquid supply branch using the one of the pairs of quick female connectors and quick male connectors;
a mounting bracket that supports the multiple node pipes, the liquid inlet unit of the flow allocator being positioned between the mounting bracket and the liquid outlet unit of the flow allocator; and
a liquid that is configured to enter the liquid inlet unit of the flow allocator through the liquid inlet, pass through one of the liquid delivery pipes to one of the node pipes, pass through the one of the node pipes to one of the liquid return pipes and then to the liquid outlet unit of the flow allocator, and exit the liquid outlet unit of the flow allocator through the liquid outlet.

12. The cabinet of claim 11 , wherein one end of either of the liquid delivery pipe and the liquid return pipe is coupled to the quick female connector, and the other end is coupled to the flow allocator.

13. The cabinet of claim 11 , wherein the liquid inlet unit of the flow allocator and the liquid outlet unit of the flow allocator are parallel to each other.

14. The cabinet of claim 11 , wherein all of the liquid delivery pipes and all of the liquid return pipes are parallel to each other.

15. The cabinet of claim 11 , wherein the liquid inlet unit of the flow allocator and the liquid outlet unit of the flow allocator are perpendicular to all of the liquid delivery pipes and all of the liquid return pipes.

16. The cabinet of claim 11 , wherein all of the pairs of quick female connectors and quick male connectors fall within a straight line that is parallel to the flow allocator.
