[0048] As an embodiment of the utility model, the device is applied to data center or industrial equipment cooling system.

[0049] From the above technical solution, the advantages and positive effects of the modular cooling liquid distribution device of the utility model are:

[0050] In the utility model, the constant pressure module 2 and the pipeline module 1 are arranged respectively, the heat exchange module 3 is arranged in multiple groups, and the quick assembly is carried out according to the demand, so that the expansion and reduction are facilitated, the maintenance, installation and transportation are facilitated.

[0051] When assembling, first, install the constant pressure module 2 at a suitable position, connect it with the pipeline module 1 through the double-sealing quick plug connector 4, ensure that the connection is firm and sealed well. Then, install the pipeline module 1, check whether the connection between the pipes is tight and whether there is leakage. Next, determine the number of heat exchange modules 3 according to the actual cooling demand, connect each heat exchange module 3 with the pipeline module 1 in turn through the interlocking valve 5. During the connection process, ensure that the sealing performance of the interlocking valve 5 and the double-sealing quick plug connector 4 is good to prevent the leakage of cooling liquid. Finally, connect and debug the power supply and control system of each module to ensure that the whole system can operate normally.

[0052] After the system is started, the power supply and control unit of the constant pressure module 2 starts to work, and the pressure sensor 35 monitors the cooling liquid pressure in the system in real time. When the pressure is insufficient, the control liquid supplementing pump is started to supplement liquid to maintain stable pressure. The pipeline module 1 uniformly distributes the constant pressure cooling liquid to each heat exchange module 3. The water pump 32 in each heat exchange module 3 sucks the cooling liquid, which is heat-exchanged by the heat exchanger 31 to reduce the temperature of the cooling liquid. The electric control valve automatically adjusts the flow and flow direction of the cooling liquid according to the parameters collected by the power supply and control system to realize accurate temperature control. The cooling liquid cooled by the heat exchange module is collected and summarized by the pipeline module 1 and then returned to the constant pressure module 2 to complete a cycle.

[0053] When the heat exchange module 3 needs to be added, first ensure that the new heat exchange module 3 is in normal working condition, then operate the interlocking valve 5 to connect it with the pipeline module 5. After the connection is completed, open the interlocking valve 5, and the new heat exchange module 3 can start to work. When the heat exchange module 3 needs to be reduced, first close the water pump and the electric control valve of the module, then operate the interlocking valve 5 to disconnect it from the pipeline module 1. After disconnection, the interlocking valve 5 will automatically seal the two sides of the pipeline to prevent the cooling liquid from leaking.

[0054] If the constant pressure module 2 needs to be replaced or maintained, first turn off the power supply of the constant pressure module 2, then disconnect it from the pipeline module 1 through the operation of the double-sealed quick plug connector 4. After the repair or replacement is completed, reconnect it to the system through the double-sealed quick plug connector 4, and debug to ensure its normal work.

[0055] Periodically check and maintain each module, including checking the water level of the liquid supplement tank of the constant pressure module 2, the working state of the pressure sensor, the sealing performance of the double-sealed quick plug connector 4; checking whether the pipeline connection of the pipeline module 1 is firm and whether there is leakage; checking whether the heat exchanger 31 of the heat exchange module 3 is clean and whether the water pump and the electric control valve are working normally. For the faulty parts, timely repair or replacement is carried out.

[0056] In summary, the modular cooling liquid distribution unit of the application effectively solves the problems of poor expandability, difficult maintenance and inconvenient installation and transportation of the existing technology through the innovative modular design, the independent power supply and control unit of the constant pressure module 2 and the application of the double-sealed quick plug connector 4 and the interlocking valve 5, which has significant economic benefits and practical value.

[0057] 1. The expandability is significantly enhanced

[0058] The user can flexibly adjust the number of heat exchange modules according to the actual cooling demand. When the cooling load increases, the cooling capacity of the system can be quickly increased by connecting new heat exchange modules to the pipeline module 1 through the interlocking valve 5; when the cooling load decreases, part of the heat exchange modules can be conveniently removed to avoid waste of energy. The independent power supply and control unit of the constant pressure module 2 can better adapt to the change of the number of system modules and ensure the stability of the system pressure. At the same time, the double-seal quick connector 4 facilitates the connection and disconnection of the constant pressure module and the distribution water pipeline, providing convenience for the expansion of the system. This modular design makes the system easily adapt to different scales and changing cooling demands, greatly improving the adaptability and economy of the system.

[0059] 2. Maintenance is more convenient

[0060] Since each module is an independent unit, when a module fails, it can be separated from the system for individual repair or replacement without affecting the normal operation of other modules and the entire system. For example, when the constant pressure module 2 fails, it can be quickly disconnected from the distribution water pipeline for repair through the double-seal quick connector 4; when a heat exchange module 3 fails, it can be isolated from the system by operating the interlocking valve 5. This not only shortens the repair time and reduces the repair cost, but also improves the reliability and stability of the system.

[0061] 3. Easy to install and transport

[0062] The modular design divides the originally large integrated system into multiple relatively small modules, and the volume and weight of each module are greatly reduced. During installation, each module can be transported and installed separately, reducing the requirements for installation space and lifting equipment; during transportation, it can also be packaged and transported more conveniently, reducing the risk of damage during transportation.

[0063] The skilled person in the technical field to which the present application pertains should understand that the specific structures and processes shown in the above detailed description are only exemplary and not limiting. Moreover, the skilled person in the technical field to which the present application pertains can combine the various technical features shown above in various possible ways to form new technical solutions, or make other modifications, all of which are within the scope of the present application.
