Description

Technical Field

[0001] This utility model relates to the field of computer heat dissipation systems, and in particular to a non-contact water cooling assembly for computers. Background Technology

[0002] Computer water cooling refers to the use of a liquid with a high specific heat coefficient (such as water) as a medium in commonly used computer cooling systems to help remove heat from internal components. Computer water cooling generally has the following advantages: minimal temperature fluctuations under circulating cooling, significant temperature control of cooled components, and stable and reliable operation over long periods; low vibration and noise when using DC (brushless) electric pumps; and a sleek overall appearance with minimal static electricity buildup.

[0003] For example, the existing Chinese utility model patent 202111026370.9 adopts a compact design, thereby integrating the heat dissipation components and the water pump. However, this design has the following problems:

[0004] 1. The water pump is quite thick, which makes the water tank part quite thick as well, affecting the overall aesthetics;

[0005] 2. The structure is complex, requiring numerous assembly and production steps. Furthermore, repairs are cumbersome when the pump drive unit malfunctions, hindering maintenance for existing users and negatively impacting the user experience.

[0006] The fit between the impeller and the drive components is complex. Utility Model Content

[0007] The main objective of this invention is to propose a non-contact water-cooled radiator assembly for computers, which aims to improve existing water-cooled radiator assemblies, reduce the thickness of their drive section, simplify assembly, and facilitate maintenance.

[0008] To achieve the above objectives, this utility model proposes a non-contact water-cooling assembly for computers, comprising:

[0009] A water tank, comprising a main body, including a first water tank and a second water tank, with a heat dissipation pipe provided between the first water tank and the second water tank;

[0010] A drive assembly, wherein the drive assembly is disposed in a first water tank and / or a second water tank;

[0011] The outer wall of the main body is provided with a pivot groove, the pivot groove is provided with a sealing plate, and the sealing plate and the cover plate form a pivot cavity.

[0012] The drive assembly includes an impeller, a permanent magnet disposed on the impeller, and a magnetic coil that cooperates with the permanent magnet.

[0013] The magnetic induction coil applies an axial driving force to the permanent magnet and drives the impeller to rotate. The magnetic induction coil and the impeller are arranged in parallel.

[0014] The impeller is pivotally mounted in the pivot cavity.

[0015] The magnetic coil is located on the outer wall of the cover plate;

[0016] The impeller can drive fluid to flow between the first water tank, the heat dissipation pipe and the second water tank (the specific flow direction can be more unidirectional or U-shaped, depending on the actual needs).

[0017] By modularizing the drive assembly and forming the impeller's pivot cavity through the pivot groove of the main body and the sealing plate, installation is simplified. Simultaneously, by directly mounting the magnetic coil on the sealing plate and arranging it parallel to the impeller, the overall thickness of the drive assembly is reduced.

[0018] Furthermore, the axial drive structure and the arrangement of the main body and impeller (the existing impeller cross-section structure is a staggered bending structure) are more planar, which reduces the overall thickness, while also lowering the mold cost and improving stability.

[0037] like Figures 1 to 6 As shown, a non-contact water-cooled assembly for computers includes:

[0038] A water tank, comprising a main body 1, a first water tank 11 and a second water tank 12, wherein a heat dissipation pipe is provided between the first water tank 11 and the second water tank 12;

[0039] Drive component 2, wherein the drive component 2 is disposed in the first water tank 11 and / or the second water tank 12;

[0040] The outer side wall of the main body 1 is provided with a pivot groove 41, the pivot groove 41 is provided with a sealing plate 5, and the sealing plate 5 and the cover plate form a pivot cavity 42.

[0041] The drive assembly includes an impeller 3, a permanent magnet 22 disposed on the impeller 3, and a magnetic coil 21 that cooperates with the permanent magnet 22.

[0042] The magnetic induction coil 21 applies an axial driving force to the permanent magnet 22 and drives the impeller 3 to rotate. The magnetic induction coil 21 and the impeller 3 are arranged in parallel.

[0043] The impeller 3 is pivotally mounted in the pivot cavity 42.

[0044] The magnetic induction coil 21 is disposed on the outer wall of the cover plate;

[0045] The impeller 3 can drive fluid to flow between the first water tank 11, the heat dissipation pipe and the second water tank 12. The specific flow direction can be a single direction or a U-shaped flow channel, which can be designed according to actual needs.

[0046] By modularizing the drive assembly and forming the pivot cavity 42 of the impeller 3 through the pivot groove 41 of the main body 1 and the sealing plate 5, installation is simplified. Meanwhile, by directly mounting the magnetic coil 21 on the sealing plate 5 and arranging the magnetic coil 21 parallel to the impeller 3, the overall thickness of the drive assembly 2 is reduced.

[0047] Furthermore, it adopts an axially driven structure. The existing cross-sectional structure of the impeller 3 is a staggered bending structure that is more planar, thereby reducing the overall thickness. At the same time, the mold cost is lower and the stability is better.

[0048] Specifically, the outer wall is the front wall, top wall, or side wall of the first water tank 11 / second water tank 12.

[0049] The design can be customized to meet specific needs; for example, the drive assembly 2 can be positioned on the front or top wall of the first water tank 11.

[0050] The drive component 2 can be installed in one or two units in a single water tank.

[0051] It can be adjusted or designed according to actual driving force requirements.

[0052] In this embodiment of the utility model, the main body 1 includes a front plate 81 and a rear plate 82, and the rear plate 82 is provided with a positioning hole for connecting to a heat sink.

[0053] The pivot groove 41 is located on the front wall of the front plate 81.

[0054] The rear wall of the front plate 81 is provided with a first cavity groove 61, a second cavity groove 62 and a flow channel groove 63;

[0055] After the rear plate 82 is installed on the rear wall of the front plate 81, it encloses the first cavity 61, the second cavity 62, and the flow channel 63 to form independent first cavities 71, second cavities 72, and flow channel 73.

[0056] The front plate 81 is provided with a water inlet and a water outlet on the side away from the drive assembly 2.

[0057] The water inlet is connected to one end of the flow channel cavity 73, and the other end of the flow channel cavity 73 is connected to the pivot cavity 42.

[0058] The pivot groove 41 is provided with a water inlet channel that penetrates the first cavity 71 in the middle.

[0059] The fluid flows into the second cavity 72 after passing through the water inlet channel and the heat dissipation pipe.

[0060] The second cavity 72 is connected to a water outlet, thereby realizing the circulation of fluid.

[0061] Specifically, a sealing ring 83 is provided between the front plate 81 and the rear plate 82 to divide the first cavity 71, the second cavity 72, and the flow channel cavity 73.

[0062] The sealing ring 83 has a dividing strip in the middle, which divides it into an upper section and a lower section.

[0063] The first cavity 71 and the second cavity 72 are located in the lower region and are spaced apart.

[0064] Specifically, the sealing ring 83 is frame-shaped, thereby ensuring the mutual sealing between the first cavity 71 and the second cavity 72, and thus ensuring the relative movement direction of the fluid.

[0065] Furthermore, it simplifies the structure and molding process.

[0066] In this embodiment of the utility model, the flow channel cavity 73 extends horizontally and is bent, thereby ensuring the connection between the water inlet and the pivot cavity 42, and ensuring the compact position and small volume.

[0067] Specifically, a sealing strip 84 is provided between the first cavity 71 and the second cavity 72. The sealing strip and the sealing ring 83 are integrally formed or separately formed, thereby satisfying the mutual independence between each cavity.

[0068] In this embodiment of the utility model, the pivot cavity 42 is arranged in a parallel and rectangular parallelepiped shape;

[0069] The front wall of the front plate 81 and the inner wall of the rear plate 82 are provided with shaft grooves 4 in opposite directions. The impeller 3 is provided with a rotating shaft 30 that cooperates with the shaft grooves 4, thereby realizing the dual-axis rotation of the impeller 3 and improving the rotation accuracy.

[0070] Specifically, the impeller 3 includes a disk 31 and blades 32 extending from the inner side of the disk 31. Multiple blades 32 are provided and distributed circumferentially along the axis.

[0071] The outer wall of the disk 31 is integrally formed with spaced permanent magnets 22.

[0072] The permanent magnet 22 is cylindrical or elongated, which ensures magnetic cutting between the permanent magnet 22 and the magnetic coil 21.

[0073] In this embodiment of the present invention, the front wall of the front plate 81 is provided with a limiting groove 51, and the limiting groove 51 is provided with positioning grooves 52 spaced apart, the positioning grooves 52 being used to install the magnetic coil 21.

[0074] The positioning grooves 52 are distributed circumferentially along the same axis;

[0075] The magnetic coil 21 is mounted on the bracket 53, the bracket 53 is provided with the positioning groove 52, and the bracket 53 can be detachably installed in the limiting groove 51.

[0076] Specifically, the magnetic induction coil 21 is connected to the control device via a PCB board or via a cable.

[0077] The magnetic induction coil 21 is an independent module, and the magnetic induction coil 21 is composed of copper wire wound with a predetermined thickness.

[0078] The magnetic induction coil 21 is a magnetic levitation coil.

[0079] The control device is used to control multiple magnetic coils 21 to be energized in a predetermined order and / or direction. Each magnetic coil 21 is an independent module and is composed of copper wire wound with a predetermined thickness.

[0080] Unlike existing designs, the magnetic coil 21 is installed directly in the positioning slot 52 as an independent unit, which allows for a higher inductance of the magnetic coil, thereby enabling a greater driving force. This allows for a higher rotational speed when the permanent magnet 22 and the magnetic coil 21 are tangent, improving equipment stability.

[0081] When multiple circumferentially distributed magnetic coils 21 are energized in a predetermined order, the permanent magnet 22 is driven.

[0082] This enables the impeller 3 to rotate, the direction of which is related to the frequency of the current and the inductance.

[0083] The magnetic induction coil 21 can be connected to the control device in series or in parallel.

[0084] For example, when using cables, independent interfaces can be used to connect to the control device. When using a PCB board, the magnetic coil 21 can be soldered to the PCB board and then installed in the positioning slot 52, thereby realizing the installation and fixation of the magnetic coil 21. For example, the PCB board can be directly installed using screws.

[0085] When not fixed to a PCB board, the magnetic coil 21 can also be fixed by a positioning cover plate.

[0086] The bracket 53 can be detachably installed in the limiting groove 51, thereby realizing the modular installation of the magnetic coil 21.

[0087] Specifically, the fluid flows sequentially into the inlet, guide cavity, pivot cavity 42, first cavity 71, heat dissipation pipe (outlet section), second water tank 12, heat dissipation pipe (return section), and finally into the second cavity 72 and outlet.

[0088] The heat pipes can be multiple in number, which can increase the contact area with the heat sink fins and improve heat exchange efficiency.

[0089] Specifically, the limiting groove 51 is also provided with an outer cover, thereby achieving relative sealing of the limiting groove.

[0090] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
