Description

Technical Field

[0001] This utility model relates to the field of heat sinks, specifically a modular water cooler with an integrated Type-C interface. Background Technology

[0002] As the power consumption of high-performance computing devices continues to increase, all-in-one liquid coolers have become standard equipment for high-end computers due to their efficient heat dissipation performance. At the same time, users' demands for personalization, functionality, and aesthetics in computers are also constantly increasing, prompting the emergence of liquid cooling products with integrated display screens and other functional modules in the market.

[0003] Currently, all-in-one liquid coolers with integrated functional modules (such as screens) have significant shortcomings in their connection methods with the water cooling pump head. They generally use separate dedicated cables to power and transmit data to the screen and other functional modules. This results in insufficient power supply, making it difficult to drive high-performance display units, low data transmission rates, and the inability to hot-swap replacements. Furthermore, non-standardized custom interfaces lead to poor expandability, preventing users from freely replacing or upgrading modules. Installation also requires connecting multiple cables, which is cumbersome and affects the aesthetics of the internal chassis.

[0004] As a modern universal standard, the Type-C interface has been widely used in the consumer electronics field due to its high-power supply (supporting the USB PD protocol), high-speed data transmission, and reversible plug-in convenience. However, this technology is still lacking in the field of all-in-one liquid cooling, especially in its application to connecting pump heads and detachable functional modules.

[0005] Therefore, there is an urgent need in this field for a new solution to overcome the shortcomings of the existing technology and provide an all-in-one water cooling system that is easier to connect, has more sufficient power supply, and is more scalable. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a modular water cooling system with an integrated Type-C interface.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] This modular water cooler with an integrated Type-C interface includes a water-cooling pump head, a heat exchanger, and water-cooling conduits connecting the pump head and the heat exchanger. The pump head uses a high-performance brushless motor to drive a centrifugal impeller, effectively propelling the coolant through a closed-loop system at high speed. The heat exchanger is made of high thermal conductivity aluminum alloy and features large, densely packed heat dissipation fins. Optimized airflow design significantly improves heat dissipation efficiency. The pump head housing integrates a first Type-C interface, a 24-pin full-function design supporting USB PD3.0 power delivery and USB 3.2 data transfer protocols. This first Type-C interface is integrated into the pump head via a PCB board and power terminals. The modular water cooler also includes a display module as a functional module. The display module has a second Type-C interface that is fully compatible with the first Type-C interface. The first Type-C interface is the female terminal, and the second Type-C interface is the male terminal. The display module is detachably connected to the pump head via the Type-C interface. When the display module approaches the water-cooled pump head, the magnetic structure allows it to automatically align and attach to the pump head, enabling blind operation and quick installation and removal. Combined with the plug-and-play nature of the Type-C interface, the installation and replacement process is greatly simplified. The two Type-C interfaces are aligned using an anti-misinsertion fixing structure, effectively preventing interface damage or connection failures caused by incorrect insertion. Once connected, a stable power supply and data transmission channel are established. The display module uses a high-brightness screen that can display system parameters such as water temperature, flow rate, and pump speed in real time, as well as user-defined animations and other content.

[0009] In one embodiment, the first Type-C interface and the second Type-C interface are provided with mutually cooperating anti-misinsertion fixing structures on their peripheries to ensure correct alignment and connection between the two interfaces, effectively preventing interface damage caused by misinsertion. Simultaneously, this anti-misinsertion fixing structure forms a stable mechanical interlock after the interfaces are connected, and also provides reliable support for the connection between the functional module and the water-cooling pump head, firmly fixing the functional module to the water-cooling pump head. This structure significantly improves the connection stability and service life of modular water cooling.

[0010] In one embodiment, the anti-misinsertion fixing structure includes a first protrusion on the periphery of one Type-C interface and a second protrusion on the periphery of the other Type-C interface. The first and second protrusions are symmetrical elliptical cylindrical walls protruding from their respective surfaces. The second protrusion has a socket cavity into which the first protrusion can be inserted. Through the cooperation between the first protrusion and the socket cavity, this structure can not only provide clear physical guidance during the connection process, ensuring that the interface can only be aligned and engaged in the only preset correct position, thereby effectively preventing mechanical or electrical damage caused by misinsertion; it can also form a stable mechanical interlock after docking, enhancing the overall rigidity of the interface area and providing reliable support and holding force for the connection point.

[0011] In one embodiment, the cross-sectional profile of the socket is the same as that of the first protrusion, and the size of the socket is larger than that of the first protrusion, thereby forming a reasonable assembly gap between them. The first protrusion is located on the periphery of the first Type-C interface of the water-cooled pump head, while the second protrusion is located on the periphery of the second Type-C interface of the functional module. When the two interfaces are mated, the first protrusion can be smoothly inserted into the socket of the second protrusion. Its matching profile and precise dimensional design achieve accurate alignment and stable connection, effectively improving the guiding and anti-displacement capabilities of the connection, while reducing wear during repeated insertion and removal.

[0012] In one embodiment, a first magnetic component is provided on the water-cooled pump head, and a corresponding second magnetic component is provided on the functional module. Through the mutual magnetic attraction between the first and second magnetic components, the functional module is quickly positioned and securely fixed on the water-cooled pump head. This magnetic attraction structure provides initial alignment guidance before interface docking and enhances the overall connection stability after connection, effectively preventing accidental detachment due to vibration or external force, thereby improving the product's reliability and ease of operation.

[0013] In one embodiment, the mating surfaces of the first and second magnetic components are provided with mutually compatible positioning structures. The positioning structures include magnetic protrusions and magnetic recesses. The magnetic protrusions can be embedded in the magnetic recesses. The first magnetic component is located on the surface of the first Type-C interface of the water-cooled pump head. The first magnetic component is a magnet and is located in the groove of the magnetic recess. The second magnetic component is located on the surface of the second Type-C interface of the functional module. The second magnetic component is a stud that can be attracted by a magnet. The stud is fixed to the surface of the functional module by threads. After the stud is fixed, the protruding nut forms the magnetic protrusion. The magnetic protrusion can be accurately embedded in the magnetic recess. The shape-matching mechanical interlocking assists in magnetic adsorption, and together the precise positioning and firm fixation of the functional module on the water-cooled pump head are achieved, effectively enhancing the connection stability and preventing displacement or loosening during use.

[0014] In one embodiment, the functional module is a display module. The display module has an LED display screen on its surface and a second Type-C interface and a second magnetic component on its back. The second Type-C interface is connected to the first Type-C interface on the surface of the water-cooling pump head to achieve power supply and high-speed data transmission. The characteristics of the Type-C interface are used to realize hot-swappable connection between the screen and the water-cooling pump head. The second magnetic component can quickly fix the display module to the water-cooling pump head, which is very convenient for DIY.

[0015] In one embodiment, the water-cooled pump head is equipped with a power supply wire that is directly connected to the internal circuitry of the water-cooled pump head, providing the necessary power support for its operation. The power supply wire has a USB power terminal for connection to a computer power supply or external adapter, ensuring the stability and security of power transmission, while meeting the power supply requirements of the water-cooled pump head under long-term high-load operating conditions.

[0016] In one embodiment, the water-cooled pump head is provided with at least two first Type-C interfaces, which are arranged symmetrically or in a matrix on the surface of the pump head, and can simultaneously establish connections with the second Type-C interfaces of two functional modules. Each interface has an independent power supply and data transmission channel, supporting the parallel operation of multiple modules. This allows for the coordinated operation of different functional modules and provides redundant expansion for modules of the same type. This design significantly improves the scalability and versatility of the system. Users can flexibly configure display, monitoring, or control modules as needed, and the modules do not interfere with each other, all achieving plug-and-play and hot-swappable operation through a unified Type-C interface.

[0017] In one embodiment, the functional module is a dedicated cover plate, which can be connected to the water-cooled pump head in two ways according to design requirements: First, it achieves physical docking and mechanical fixation with the pump head through a surface-mounted anti-misinsertion fixing structure. In this case, the cover plate may not integrate a Type-C interface and can be used as a decorative or auxiliary functional module. Second, it directly docks with the first Type-C interface on the pump head through a second Type-C interface on the cover plate, relying on the interface's own mechanical structure for connection and fixation. Both methods ensure reliable installation of the cover plate, providing users with flexible functional expansion options. This satisfies non-electronic functional requirements such as pure decoration or heat dissipation, and also reserves compatibility for future upgrades to electrically powered modules.

[0018] The beneficial effects of this utility model are:

[0019] This utility model, by adopting the above-mentioned technical solution and using a Type-C interface for connection, combined with a magnetic and anti-misinsertion fixing structure, significantly improves the connection reliability and user experience of modular water cooling. It not only provides strong and stable power supply and efficient data transmission, but also features a standardized interface that enables plug-and-play and hot-swappable functional modules. Users can easily replace or upgrade modules with different functions, greatly enhancing the product's versatility and playability. The magnetic structure allows functional modules to automatically align and attach to the water cooling pump head, enabling blind operation and quick assembly / disassembly. Combined with the plug-and-play nature of the Type-C interface, the installation and replacement process is greatly simplified. The anti-misinsertion fixing structure ensures that the Type-C interface can only be connected in one correct position through physical limiting, effectively preventing interface damage or connection failure caused by misinsertion, and significantly improving the product's reliability and durability.

[0032] A modular water cooler with an integrated Type-C interface includes a water-cooled pump head 2, a heat radiator, and water-cooled conduits connecting the pump head 2 and the heat radiator. The pump head 2 is provided with a first Type-C interface 3. The modular water cooler also includes at least one functional module 1. The functional module 1 is provided with a second Type-C interface 4 that matches the first Type-C interface 3. The functional module 1 is detachably connected to the pump head 2 through the cooperation of the first Type-C interface 3 and the second Type-C interface 4, and performs power and data transmission.

[0033] By adopting the above technical solution, a unified approach to high-performance heat dissipation and rapid connection of functional module 1 is achieved. The water-cooled pump head 2 and high-performance heat sink are connected via water-cooling conduits: the water-cooled pump head 2 uses a high-performance brushless motor to drive a centrifugal impeller, ensuring high-speed flow of coolant in a closed-loop system; the heat sink is made of high thermal conductivity aluminum alloy and equipped with large-area, dense heat dissipation fins, combined with an optimized airflow design, significantly improving heat dissipation efficiency. The housing of the water-cooled pump head 2 integrates a 24-pin full-function Type-C female interface compliant with the USB PD 3.0 power supply protocol and the USB 3.2 data transmission protocol, reliably connected to the internal circuitry via the PCB board. The equipped functional module has a Type-C male interface matching its Type-C female interface, which achieves automatic alignment and rapid adsorption through a magnetic structure, and a mis-insertion prevention fixing structure ensures accurate and reliable connection. This design not only achieves convenient plug-and-play installation but also establishes a stable power supply and high-speed data transmission channel. One type of functional module uses a high-brightness LCD display screen, which can display system parameters such as water temperature, flow rate, and rotation speed in real time, and supports the display of user-defined content, providing an immersive visual experience. Another type is a cover plate with light strips or other devices that require power and have a Type-C interface, which can be plugged and played, allowing users to freely expand and making it very convenient for DIY.

[0034] Preferably, the first Type-C interface 3 and the second Type-C interface 4 are provided with mutually cooperating anti-misinsertion fixing structures on their periphery to ensure correct alignment and connection between the two interfaces and to fix the functional module 1 to the water-cooled pump head 2.

[0035] By adopting the above technical solution, a mutually cooperating anti-misinsertion fixing structure is set around the first Type-C interface 3 and the second Type-C interface 4, effectively ensuring that the two interfaces can only be connected in the single correct relative position, fundamentally avoiding mechanical or electrical damage to the interfaces caused by misinsertion. After the interfaces are connected, this structure further forms a stable mechanical interlock, providing reliable support for the connection between the functional module 1 and the water-cooled pump head 2, and firmly fixing the functional module 1 to the water-cooled pump head 2. This significantly enhances the connection stability of the modular water-cooling system under vibration environments and extends the product's service life.

[0036] Preferably, the anti-misinsertion fixing structure includes a first protrusion 5 disposed on the periphery of one of its Type-C interfaces and a second protrusion 6 disposed on the periphery of the other Type-C interface. The second protrusion 6 is provided with a socket cavity, and the first protrusion 5 can be inserted into the socket cavity.

[0037] By adopting the above technical solution, the anti-misinsertion fixing structure achieves precise docking by setting a first protrusion 5 and a second protrusion 6 on the periphery of the two Type-C interfaces, respectively. The second protrusion 6 has a socket cavity into which the first protrusion 5 can be precisely inserted. The first and second protrusions 5 and 6 adopt a symmetrical elliptical cylindrical wall design, protruding from their respective mounting surfaces. The cooperation between the protrusions and the socket cavity provides clear physical guidance during the connection process, ensuring that the interfaces can only dock in one correct orientation, effectively preventing mechanical or electrical damage caused by misinsertion; it also forms a stable mechanical interlock after docking, significantly enhancing the overall rigidity of the interface area, providing reliable support and holding force for the connection point, and comprehensively improving the stability and durability of the connection.

[0038] Preferably, the cross-sectional profile of the socket cavity is the same as that of the first protrusion 5, and the size of the socket cavity is larger than that of the first protrusion 5. The first protrusion 5 is located on the periphery of the first Type-C interface 3 of the water-cooled pump head 2, and the second protrusion 6 is located on the periphery of the second Type-C interface 4 of the functional module 1.

[0039] By adopting the above technical solution, the cross-sectional profile of the socket cavity is consistent with the cross-sectional profile of the first protrusion 5, and the size of the socket cavity is slightly larger than that of the first protrusion 5, thereby forming a reasonable assembly gap between the two. The first protrusion 5 is located on the periphery of the first Type-C interface 3 of the water-cooled pump head 2, while the second protrusion 6 and the socket cavity are located on the periphery of the second Type-C interface 4 of the functional module 1. When the interfaces are mated, the first protrusion 5 can be smoothly inserted into the socket cavity due to its matching profile design and precise dimensional fit, achieving accurate alignment and stable connection. This structure not only significantly improves the guiding accuracy and anti-offset capability during connection, but also effectively reduces wear during repeated insertion and removal processes through optimized gap control, extending the service life of the interface.

[0040] Preferably, the water-cooled pump head 2 is provided with a first magnetic element 7, and the functional module 1 is provided with a second magnetic element 8. The first magnetic element 7 and the second magnetic element 8 attract each other to fix the functional module 1 on the water-cooled pump head 2.

[0041] By adopting the above technical solution, the water-cooled pump head 2 is provided with a first magnetic component 7, and the functional module 1 is correspondingly provided with a second magnetic component 8. Utilizing the mutual magnetic attraction between the first magnetic component 7 and the second magnetic component 8, the functional module 1 is quickly positioned and firmly fixed on the water-cooled pump head 2. This magnetic attraction structure can provide preliminary alignment guidance before Type-C interface docking, assisting in achieving precise docking; after connection, it further enhances the overall mechanical stability of the connection, effectively resisting vibration and external impact, preventing accidental detachment, and significantly improving the product's reliability, safety, and ease of operation.

[0042] Preferably, the mating surfaces of the first magnetic element 7 and the second magnetic element 8 are provided with mutually compatible positioning structures. The positioning structures include magnetic protrusions 10 and magnetic recesses 11, and the magnetic protrusions 10 can be embedded in the magnetic recesses 11.

[0043] By adopting the above technical solution, the positioning structure includes mutually matching magnetic protrusions 10 and magnetic recesses 11. The first magnetic component 7 is a magnet, which is embedded in the groove of the magnetic recess 11 on the surface of the first Type-C interface 3 of the water-cooled pump head 2. The second magnetic component 8 is a stud that can be attracted by the magnet, which is located on the surface of the second Type-C interface 4 of the functional module 1. The stud is fixed to the surface of the functional module 1 by threads, and its protruding nut constitutes the magnetic protrusion 10. With the shape matching design of the magnetic protrusion 10 and the magnetic recess 11, precise embedding and matching are achieved, forming a mechanical interlock. Combined with the magnetic adsorption effect, the functional module 1 is accurately positioned and firmly fixed on the water-cooled pump head 2, effectively enhancing the connection stability and preventing displacement or loosening during use.

[0044] Preferably, the functional module 1 is a display module, and the display module is electrically connected to the water-cooled pump head 2 through a first Type-C interface 3 and a second Type-C interface 4.

[0045] By adopting the above technical solution, the functional module 1 adopts a display module, which is a high-brightness LCD screen. The display screen realizes a quick hot-swap plug-in connection between the screen and the water-cooled pump head through the Type-C interface set on each connection surface, which is very convenient for DIY.

[0046] Preferably, the water-cooled pump head 2 is provided with a power supply wire 9, which supplies power to the water-cooled pump head 2.

[0047] By adopting the above technical solution, the power supply wire 9 is directly connected to the internal circuit of the water-cooled pump head 2, providing stable and reliable power support for its operation. The end of the wire is equipped with a standard USB power supply terminal, which can be quickly connected to a computer power supply or external adapter, ensuring efficient power transmission in different working environments. The power supply wire 9 uses highly conductive materials and a multi-layered insulation protection design, combining transmission stability and usage safety, and can fully meet the power supply requirements of the water-cooled pump head 2 for long-term high-load operation.

[0048] Preferably, the water-cooled pump head 2 is provided with at least two first Type-C interfaces 3, which can be connected to the second Type-C interfaces 4 of the two functional modules 1 respectively.

[0049] By adopting the above technical solution, multiple interfaces are arranged symmetrically or in a matrix on the pump head surface, and can simultaneously establish connections with the second Type-C interface 4 of each of the two functional modules 1. Each interface has an independent power supply and data transmission channel, supporting the collaborative work of different functional modules 1 such as display and monitoring, or redundant expansion of similar modules. This design significantly enhances the system's scalability and versatility, allowing users to flexibly configure various modules as needed. The unified Type-C standard for all interfaces not only ensures no interference between modules but also provides a convenient plug-and-play and hot-swappable operating experience.

[0050] Preferably, the functional module 1 is a cover plate, which is provided with an anti-misinsertion fixing structure to connect and fix the water-cooled pump head 2.

[0051] By adopting the above technical solution, the cover plate provides two connection methods with the water-cooled pump head 2: one method uses an anti-misinsertion fixing structure on its surface to achieve physical docking and mechanical fixation with the pump head. This method does not require the integration of a Type-C interface and is suitable for non-electronic functions such as decoration or auxiliary heat dissipation; the other method uses a second Type-C interface integrated on the cover plate to directly dock with the first Type-C interface on the pump head, using the interface's own mechanical structure for fixation. Both connection methods ensure the reliability of the cover plate installation, provide users with flexible functional expansion options, meet current decorative and heat dissipation needs, and also reserve compatibility for future upgrades to the electrically powered module 1.

[0052] Working principle: It uses a Type-C interface for connection, combined with a magnetic and anti-misinsertion fixing structure, which significantly improves the connection reliability and user experience of modular water cooling.

[0053] During installation, install the radiator inside the chassis, connect the wires, and insert the required functional module 1 into the water-cooled pump head 2 as needed to complete the installation.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
