Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation technology, specifically to a multi-module liquid cooling heat dissipation system. Background Technology
[0002] In the field of frequency converters, with the continuous increase in power density, traditional air-cooling methods face problems such as high noise and insufficient heat dissipation efficiency, especially in high-temperature and humid environments, making it difficult to meet the stable operation requirements of frequency converters.
[0003] To address this pain point, Chinese patent CN221448284U proposes a frequency converter with a water cooling system. It adopts a combined air and water cooling mode, with a water-cooled plate as the core heat dissipation component and a cooling fan to assist in heat dissipation. This effectively reduces air-cooling noise and improves heat dissipation in high-temperature and humid environments, providing an important reference for the heat dissipation design of frequency converters.
[0004] However, in liquid cooling scenarios for multi-module, high-power equipment, the aforementioned frequency converters with water circuit systems still have shortcomings. They exhibit significant fragmentation in modular management, lacking a standardized modular system, resulting in poor system expansion flexibility and a substantial increase in operation and maintenance costs.
[0005] Therefore, there is an urgent need for a modular liquid cooling system. Utility Model Content
[0006] This utility model addresses the technical problems existing in the prior art by providing a multi-module liquid cooling heat dissipation system.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-module liquid cooling system includes a main water inlet pipe, an inlet water divider module, a main water outlet pipe, an outlet water divider module, and a liquid cooling module. The main water inlet pipe connects to multiple inlet water divider modules, and each inlet water divider module is connected to the inlet of each liquid cooling module via an inlet water pipe. The main water outlet pipe connects to multiple outlet water divider modules, and each outlet water divider module is connected to the outlet of each liquid cooling module via an outlet water pipe. The liquid cooling module is in close contact with the heat-generating components.
[0008] The beneficial effects of this utility model are: The main water pipe connects to the liquid cooling module via a manifold module, forming a standardized hierarchical architecture. This breaks away from the decentralized design of rigid one-to-one connections in existing technologies, enabling modular integration of the liquid cooling system. The manifold module, acting as an intermediate adapter layer, can flexibly connect to multiple liquid cooling modules simultaneously, solving the problems of difficult expansion and poor adaptability in traditional solutions. Maintenance personnel only need to push the liquid cooling module into its designed position to complete all liquid circuit connections at once, reducing the difficulty and risk of liquid cooling module installation and simplifying the installation process. At the same time, the replacement and maintenance of the liquid cooling module does not require draining the coolant, improving the maintenance efficiency of the power module.
[0009] Furthermore, both the main inlet pipe and the main outlet pipe are integral structures. The main inlet pipe connects to an external water source, and has multiple inlet outlets, each connected to an inlet distributor module via a flexible hose. The main outlet pipe connects to an external return water system, and has multiple outlet outlets, each connected to an outlet distributor module via a flexible hose. This integral structure reduces pipe joints and lowers the risk of coolant leakage. The main inlet and multiple outlets allow for centralized coolant distribution and recovery, avoiding uneven flow in dispersed pipes. The flexibility of the flexible hoses also compensates for installation misalignments between the main pipe and the distributor module.
[0010] Furthermore, both the main inlet and outlet water pipes are modular structures, connected by T-joints. These T-joints also connect to either the inlet or outlet water distribution module via flexible hoses. This modular structure, achieved through T-joints, allows for segmented assembly of the main water pipe, overcoming the space limitations imposed by monolithic pipes and enhancing the system's adaptability to equipment of different sizes and layouts, making it more suitable for large equipment or complex installation scenarios.
[0011] Furthermore, both the main inlet and outlet water pipes are equipped with pressure and temperature sensors. This allows for real-time monitoring of the pressure and temperature within the water pipes, enabling timely detection of malfunctions such as coolant leaks and insufficient flow.
[0012] Furthermore, an inlet vent valve is installed at the top of the main water inlet pipe. The vent valve can release the gas accumulated in the main water inlet pipe, preventing air blockage in the pipeline.
[0013] Furthermore, each of the inlet and outlet water distributor modules includes two or more water distributors connected by flexible hoses. Multiple water distributors forming a module via flexible hoses avoids the cumulative errors caused by cabinet manufacturing and the installation of a single water distributor within the cabinet, which could prevent the liquid cooling module from being plugged in or unplugged. Simultaneously, water distributors can be flexibly added or removed according to the number of liquid cooling modules, enhancing the system's modular expansion capability. Moreover, the flexible hose connection can offset dimensional errors in the water distributor's own manufacturing, completely solving the problem of insufficient plugging and unplugging accuracy in existing technologies, and also facilitating the disassembly and replacement of water distributor modules, reducing maintenance difficulty.
[0014] Furthermore, each branch of the water distributor is equipped with a blind-plug socket. The blind-plug socket enables quick plug-in and plug-out operations. The liquid cooling module and each branch of the water distributor are connected by blind plugging, eliminating the need for maintenance personnel to perform precise docking operations inside the cabinet. This reduces the technical requirements for operators, avoids the risk of coolant leakage due to improper installation, and solves the accuracy problems when plugging and unplugging multiple modules simultaneously inside the cabinet.
[0015] Furthermore, in the inlet and outlet water distributor modules, the specifications of each water distributor may be the same or different. This allows for the use of water distributors of the same or different specifications within the water distributor module, enabling flexible matching of water distributors according to the heat dissipation requirements of each liquid cooling module. This breaks the limitation of a single specification and improves the system's adaptability to different power and types of heat-generating components. Attached Figure Description

Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0022] Example 1 like Figure 1 , Figure 2 As shown in the figure, this embodiment discloses a multi-module liquid cooling system, including a main water inlet pipe 1, an inlet water distributor module 2, a main water outlet pipe 3, an outlet water distributor module 4, and a liquid cooling module (the liquid cooling module is prior art and is not shown in the figure). The main water inlet pipe 1 connects to multiple inlet water distributor modules 2, and the inlet water distributor modules 2 are connected to the inlets of each liquid cooling module through inlet water pipes. The main water outlet pipe 3 connects to multiple outlet water distributor modules 4, and the outlet water distributor modules 4 are connected to the outlets of each liquid cooling module through outlet water pipes. The liquid cooling module is tightly fitted to the heat-generating components. The purpose of this embodiment is to form a standardized hierarchical architecture, break the decentralized design of one-to-one rigid connection in the prior art, realize the modular integration of the liquid cooling system, use the water distributor module as an intermediate adaptation layer to flexibly connect multiple liquid cooling modules, and solve the problems of difficult expansion and poor adaptability of traditional solutions. At the same time, it completes all liquid circuit connections at one time, simplifies the installation process of the liquid cooling module, and improves the maintenance efficiency of the power module.
[0023] Specifically: Both the main inlet pipe 1 and the main outlet pipe 3 are modular structures, connected by a T-joint 5. The T-joint 5 is also connected to the inlet water distributor module 2 or the outlet water distributor module 4 via a water distribution hose 6. The modular structure allows for segmented splicing of the main water pipe through the T-joint 5, overcoming the limitations of the integral water pipe on installation space and improving the system's adaptability to equipment of different sizes and layouts, making it more suitable for large equipment or complex installation scenarios. At the same time, the segmented design facilitates local maintenance; if a section of the water pipe fails, there is no need to replace the entire pipe, reducing maintenance costs and downtime. Furthermore, the flexibility of the water distribution hose 6 can compensate for installation deviations between the main water pipe and the water distributor module, solving the problem of difficult module insertion and removal caused by rigid connections, and improving system installation compatibility.
[0024] Both the main inlet pipe 1 and the main outlet pipe 3 are equipped with pressure sensors and temperature sensors (not shown in the figure). These sensors enable real-time monitoring of the pressure and temperature within the pipes, allowing for timely detection of faults such as coolant leaks (sudden pressure drops) and insufficient flow (abnormal temperature increases), preventing equipment damage caused by escalating faults. Furthermore, they dynamically optimize heat dissipation parameters based on the actual needs of heat-generating components, achieving on-demand heat dissipation and reducing energy consumption.
[0025] The top of the main water inlet pipe 1 is equipped with an inlet vent valve 7. The vent valve can discharge the gas accumulated in the main water inlet pipe 1, preventing air blockage in the pipe. Air blockage can lead to poor coolant flow, reduced heat dissipation efficiency, and even localized overheating. The vent valve ensures that the coolant flows through the pipe, ensuring stable heat dissipation, and at the same time reduces the oxidation and corrosion of the inner wall of the pipe by air, extending the service life of the main water pipe.
[0026] Each of the inlet water distributor module 2 and outlet water distributor module 4 includes two or more water distributors, which are connected by flexible hoses 8. Multiple water distributors are connected by flexible hoses 8 to form a module, avoiding the cumulative errors caused by cabinet manufacturing and the installation of a single water distributor inside the cabinet, which could prevent the liquid cooling module from being plugged in or unplugged. Furthermore, water distributors can be flexibly added or removed according to the number of liquid cooling modules, improving the system's modular expansion capability. Moreover, the connection of flexible hoses 8 can compensate for dimensional errors in the manufacturing of the water distributors themselves, completely solving the problem of insufficient plugging and unplugging accuracy of multiple modules in the prior art. It also facilitates the disassembly and replacement of water distributor modules, reducing maintenance difficulty.
[0027] Each branch of the water distributor is equipped with a blind-plug socket 9. The blind-plug socket 9 is existing technology. The blind-plug socket 9 enables quick plug-in and unplugging operations between the liquid cooling module and the water distributor branch, allowing for immediate connection upon pushing in and immediate sealing upon pulling out, thus shortening module replacement time. Moreover, the blind-plugging between the liquid cooling module and each water distributor branch eliminates the need for maintenance personnel to perform precise docking operations inside the cabinet, reducing the technical requirements for operators. It also avoids the risk of coolant leakage due to improper installation and solves the accuracy problems of simultaneous plugging and unplugging of multiple modules inside the cabinet and during installation.
[0028] In the inlet water distributor module 2 and the outlet water distributor module 4, the specifications of each water distributor may be the same or different. The water distributor module allows for the use of water distributors of the same or different specifications. Water distributors can be flexibly matched according to the heat dissipation requirements (such as flow rate and pressure) of each liquid cooling module. For example, high-power liquid cooling modules can correspond to large-diameter water distributors, while low-power modules can correspond to small-diameter water distributors, achieving precise distribution of coolant and avoiding energy waste. This breaks the limitation of a single specification and improves the system's adaptability to different power and types of heat-generating components.
[0029] Example 2 It is basically the same as Example 1, except that: Both the main inlet pipe 1 and the main outlet pipe 3 are integral structures. The main inlet of the main inlet pipe 1 connects to an external water source, and multiple inlet outlets are provided on the main inlet pipe 1. Each inlet outlet is connected to an inlet / outlet water distributor module 2 via a water distribution hose 6. The main outlet of the main outlet pipe 3 connects to an external return water system, and multiple outlet outlets are provided on the main outlet pipe 3. Each outlet outlet is connected to an outlet water distributor module 4 via a water distribution hose 6. The integral structure reduces pipe splicing points and lowers the risk of coolant leakage. At the same time, the design of the main outlet and multiple outlets enables centralized distribution and recovery of coolant, avoiding the problem of uneven flow in dispersed pipes. Moreover, the unified connection between the external water source and the return water system simplifies the pipe layout, reduces the complexity of system construction, and facilitates unified maintenance in the future.
