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

The invention 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 provided at a liquid inlet unit of the flow allocator, and the liquid outlet being provided at a liquid outlet unit of the flow allocator;
multiple liquid supply branches in a one-to-one correspondence to multiple device handle bars, multiple electronic devices in a one-to-one correspondence to the multiple device handle bars, each of the liquid supply branches passing one of the electronic devices behind the corresponding device handle bar, each of the liquid supply branches comprising a liquid delivery pipe and a liquid return pipe that communicate with the flow allocator, 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; and
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.

2. The cabinet liquid cooling system of claim 1 , wherein the liquid inlet unit and the liquid outlet unit are both installed on a same side of the cabinet or are separately installed on two sides of the cabinet, and are located in the space between the side wall of the cabinet and the mounting bar of the cabinet, the liquid inlet is provided at the bottom or in the middle of the liquid inlet unit, the liquid outlet is provided at the bottom or in the middle of the liquid outlet unit, the liquid delivery pipe is coupled to the liquid inlet unit, and the liquid return pipe is coupled to the liquid outlet unit.

3. The cabinet liquid cooling system of claim 1 , wherein the system further comprises 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.

4. The cabinet liquid cooling system of claim 1 , wherein the system further comprises 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.

5. The cabinet liquid cooling system of claim 4 , wherein the quick female connector and the quick male connector are mutually suspended and inserted for cooperation, and are fastened by using a slidable sleeve; the slidable sleeve, the quick female connector, and the quick male connector are coaxial, and the slidable sleeve is axially movable.

6. The cabinet liquid cooling system of claim 5 , wherein the quick female connector and the slidable sleeve are clamped and secured by using the mounting bracket, the mounting bracket is formed by butting a lower mounting bracket and an upper mounting bracket that have a same structure, is locked by using a screw or a bolt and a tapped hole that is provided on the mounting bracket, and is then securely installed on an inner side of the side wall of the cabinet by using a screw or a bolt.

7. The cabinet liquid cooling system of claim 6 , wherein both the lower mounting bracket and the upper mounting bracket are internally provided with accommodating space for disposing the quick female connector and the slidable sleeve and holes that are provided on two sides of the accommodating space and lead to the accommodating space, and a shape and a structure of the accommodating space match shapes of the quick female connector and the slidable sleeve.

8. The cabinet liquid cooling system of claim 7 , wherein a size of the hole is less than a size of a cross section of either of the quick female connector and the slidable sleeve.

9. The cabinet liquid cooling system of claim 6 , wherein both the lower mounting bracket and the upper mounting bracket are only internally provided with accommodating space for disposing the quick female connector and holes that are provided on two sides of the accommodating space and lead to the accommodating space, and a shape and a structure of the accommodating space match a shape of the quick female connector.

10. The cabinet liquid cooling system of claim 9 , wherein the mounting bracket further comprises a spring plate and a button ejector pin, and the slidable sleeve is provided with a groove portion; the spring plate is of an arch-shaped structure, has a middle portion and two bending portions connected to two edges of the middle portion, the middle portion is provided with a long-strip-shaped hole, and one of the bending portions is provided with an arc-shaped hole that cooperates with the quick male connector and is connected to the long-strip-shaped hole; the bending portion provided with the arc-shaped hole abuts the groove portion of the slidable sleeve, and the other bending portion is secured to the lower mounting bracket; the button ejector pin is provided with a bending section and an ejector pin section, the bending section is secured to the bending portion that is in the spring plate and is provided with the arc-shaped hole, and the ejector pin section is far away from the spring plate.

11. The cabinet liquid cooling system of claim 9 , wherein a size of the hole is less than a size of a cross section of the quick female connector.

12. 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.

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

14. A cabinet comprising multiple 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 provided at a liquid inlet unit of the flow allocator, and the liquid outlet being provided at a liquid outlet unit of the flow allocator;
