Description

Technical Field

[0001] The utility model relates to the field of utility models, and particularly relates to a cooling component for a contactless driving structure of a computer. Background Art

[0002] Computer water cooling refers to a common liquid cooling system in a computer, which uses a liquid with a high specific heat coefficient (such as water) as a medium to assist in removing the heat of internal components. Computer water cooling generally has the following advantages: small temperature fluctuation under cyclic cooling, obvious temperature control effect on the cooled components, and stable and reliable long-term use.

[0003] In the existing integrated design of a water pump and a water chamber, in order to drive the impeller with a brushless motor, the rotor is generally arranged inside the impeller. However, the magnetic induction coil of the stator needs to be tangent to the device (that is, the stator is a magnetic induction coil, and the rotor is arranged on the outer periphery of the stator, being radially tangent). Then, the housing will protrude and extend into the water chamber, thereby realizing the impeller driving the fluid to flow. The corresponding problem is that the volume of the water chamber is large, and at the same time, the thickness is also large. Moreover, since the housing of the stator extends into the water chamber, the volume of the water chamber will also decrease accordingly.

[0004] Of course, there is also a structure with a separate water pump and water chamber. Correspondingly, its integrity is poor, and with the setting of a transparent computer case, the water pump and water chamber are relatively large, which also affects the overall aesthetics of the computer case. Summary of the Invention

[0005] The main purpose of the utility model is to propose a cooling component for a contactless driving structure of a computer, aiming to realize the integrated setting of a water pump and a water chamber, with a simple structure, and at the same time reduce its overall volume while ensuring the volume of the water chamber.

[0006] To achieve the above purpose, the utility model proposes a cooling component for a contactless driving structure of a computer, including:

[0007] A water chamber, the water chamber is a housing provided with an inner cavity, the top wall of the inner cavity is pivotally provided with an impeller, and the upper part of the impeller is a disk extending radially;

[0008] The housing is provided with a fluid inlet and a fluid outlet;

[0009] A driving device, the driving device includes a pump seat arranged on the upper wall of the water chamber, the pump seat is fixedly provided with a stator, the stator is provided with a rotor that cooperates with each other, the rotor and the stator are radially arranged, the rotor is located below the stator, and the magnetic fields of the stator and the rotor are axially tangent;

[0010] The rotor is arranged on the disk or the rotor drives the disk to rotate through an intermediate member;

[0011] The top wall of the water chamber is a partition plate provided between the stator and the disc;

[0012] When the impeller rotates, the impeller can drive the fluid to flow from the fluid inlet through the water chamber and then into the fluid outlet.

[0013] In actual design, the water chamber is a relatively closed housing. Therefore, if a pivoting impeller is provided on its top wall, the impeller and the pump housing are not connected to each other. Through the axially arranged stator, the axially arranged rotor is driven to rotate. The rotor can be directly arranged on the disc, or the rotor can drive the disc to rotate through an intermediate member;

[0014] Its advantages are as follows:

[0015] 1. The water chamber and the pump base are two independent chambers. Therefore, the fluid will not affect the circuit elements, ensuring the service life and use safety of the driving device;

[0016] 2. The stator and the rotor are arranged radially, and then axially tangent, reducing the overall thickness of the driving device. At the same time, the volume of the integrated structure of the water chamber and the pump base is smaller, effectively improving the aesthetics of the computer water cooling structure;

[0017] 3. The structure is simpler. There is no need for a concave-convex structure between the water chamber and the pump chamber to achieve the tangency of the stator and the rotor. A radial structure can be used, so the mold production cost is lower, effectively improving the market competitiveness;

[0018] 4. Under the same output torque, rotational speed and power conditions, compared with the radial flux motor, the axial flux motor (i.e., the driving device of the present application): the axial dimension is shortened by more than 50%, which is more suitable for occasions with high space requirements; the weight is reduced by about 50%, which can increase the mobility of the equipment and achieve lightweight.

[0019] The direction of the pump base can be set vertically or horizontally;

[0020] 5. There is no rigid connection between the rotor and the impeller. When the resistance of the impeller is greater than a predetermined value, the motor (i.e., the magnetic induction coil) will not burn out due to internal resistance;

[0021] Especially for some problems where the rotor may get stuck or move slowly when the output power is increased after the inside of the pump body is blocked (i.e., a greater torque needs to be output), the service life of the water pump is effectively improved. Description of the Drawings

[0041] As Figures 1 to 8 shown, a cooling assembly for a computer contactless drive structure includes:

[0042] A water chamber 1, where the water chamber 1 is a housing with an inner cavity 10 (the housing includes an upper shell 102 and a bottom cover 101, the shunt layer 40 and the bottom cover 101 are integrally formed, and an opening is provided at the lower end of the upper shell 102, and a slot for installing a sealing ring is provided at the position of the opening to make the opening and the bottom cover 101 relatively sealed). A pivotally mounted impeller 2 is provided on the top wall of the inner cavity 10. The upper part of the impeller 2 is a disk 21 extending radially.

[0043] The housing is provided with a fluid inlet 11 and a fluid outlet 12;

[0044] A driving device 3, where the driving device 3 includes a pump seat 30 provided on the upper wall of the water chamber 1. The pump seat 30 is fixedly provided with a stator 31. The stator 31 is provided with a mutually cooperating rotor 32. The rotor 32 and the stator 31 are radially arranged. The rotor 32 is located below the stator 31, and the magnetic fields of the stator 31 and the rotor 32 are axially tangent;

[0045] The rotor 32 is provided on the disk 21 or the rotor 32 drives the disk 21 to rotate through an intermediate member (i.e., a first magnetic member and a second magnetic member);

[0046] The top wall of the water chamber 1 is a partition 13 provided between the stator 31 and the disk 21;

[0047] When the impeller 2 rotates, the impeller 2 can drive the fluid to flow from the fluid inlet 11 through the water chamber 1 and into the fluid outlet 12.

[0048] In the actual design, the water chamber 1 is a relatively enclosed housing. Therefore, a pivotable impeller 2 is provided on its top wall. Then, the impeller 2 and the pump housing are not connected to each other. Through the axially arranged stator 31, the axially arranged rotor 32 is driven to rotate. The rotor 32 can be directly arranged on the disk 21, or the rotor 32 can also drive the disk 21 to rotate through an intermediate member.

[0049] Its advantages are as follows:

[0050] 1. The water chamber 1 and the pump base 30 are two independent chambers. Therefore, the fluid will not affect the circuit elements, ensuring the service life and use safety of the driving device 3.

[0051] 2. The stator 31 and the rotor 32 are radially arranged, and then axially tangent, reducing the overall thickness of the driving device 3. At the same time, the volume of the integrated structure of the water chamber 1 and the pump base 30 is smaller, effectively improving the aesthetics of the computer water cooling structure.

[0052] 3. The structure is simpler. There is no need for a concave-convex structure between the water chamber 1 and the pump chamber to achieve the tangency of the stator 31 and the rotor 32. A radial structure can be used, so the mold production cost is lower, effectively improving the market competitiveness.

[0053] 4. Under the same output torque, rotational speed and power conditions, compared with the radial flux motor, the axial flux motor (i.e., the driving device 3 of the present application): the axial dimension is shortened by more than 50%, which is more suitable for occasions with high space requirements; the weight is reduced by about 50%, which can further increase the mobility of the equipment and achieve lightweight.

[0054] The direction of the pump base 30 can be set vertically or horizontally.

[0055] Specifically, the bottom wall of the water chamber 1 is a heat conducting surface 4.

[0056] Specifically, a convex diversion layer 40 is provided on the wall surface of the bottom wall of the inner cavity 10 opposite to the heat conducting surface 4. In the actual design, the cold head, the water chamber 1 and the pump base 30 are integrally arranged. Then, the cooling assembly can be directly installed on the heat generating elements (such as the graphics card and the CPU), and has a small volume and good stability. At the same time, the axial driving device 3 is adopted to reduce its overall thickness and weight, facilitating its installation. The diversion layer 40 is used to increase the contact area between the fluid and the bottom wall of the inner cavity 10, thereby improving the heat exchange effect of the diversion surface.

[0057] Specifically, the diverter layer 40 is composed of a plurality of heat-conducting strips 41 disposed at intervals, and a guide groove 42 is formed between two heat-conducting strips 41, so that the fluid can flow in a predetermined direction, thereby improving the heat exchange efficiency.

[0058] Specifically, the stator 31 includes a bracket 310 and a magnetic induction coil 311 arranged at intervals on the bracket 310, and the magnetic induction direction of the magnetic induction coil 311 is axial; the rotor 32 is provided with a plurality of permanent magnets 320. Its structure can be referred to as an axial flux motor, and the rotation of the rotor 32 is controlled by controlling the direction of the current.

[0059] In the first embodiment, when the permanent magnet 320 is arranged on the disk 21, the stator 31 directly drives the permanent magnet 320 and drives the impeller 2 to rotate, and the partition 13 is arranged between the stator 31 and the rotor 32. This structure eliminates the air gap, thereby changing the problem of unstable heat dissipation of the axial flux motor, that is, the rotor 32 is located in the water chamber 1, which can fully dissipate heat. In principle, the magnetic field of the permanent magnet 320 is stable, and the corresponding main damaged component is the stator 31 (that is, the magnetic induction coil 311 part). Therefore, even if the cooling component is damaged, the stator 31 can be replaced, which effectively improves the convenience of maintenance.

[0060] Specifically, the rotor 32 and the disk 21 are integrally injection molded, thereby effectively protecting the structure of the stator 31 and improving the stability of the permanent magnet 320 .

[0061] Specifically, the magnetic field projection areas of the stator 31 and the rotor 32 are consistent, thereby ensuring the driving stability and avoiding the problem of magnetic field loss.

[0062] Specifically, the permanent magnets 320 are distributed on the rotor 32 in a fan shape. The permanent magnets 320 include an S pole and an N pole. The S pole and the N pole are disposed adjacent to each other, thereby achieving tangent magnetic fields.

[0063] In the second embodiment, the rotor 32 is pivotally mounted between the upper wall of the water chamber 1 and the pump seat 30, the rotor is provided with a first magnetic member, the first magnetic member is the permanent magnet, the disc 21 is provided with a second magnetic member 322 matched with the first magnetic member 321, and the partition 13 is provided between the rotor 32 and the disc 21. Generally speaking, the rotor 32 is also provided with an iron core and other structures for fixing the permanent magnet 320. When the permanent magnet 320 is integrally injection molded, the use of the iron core can be reduced to fix its magnetic pole.

[0064] Specifically, the bracket 310 is a PCB board or an iron core. In actual design, it is preferred to use a PCB board to wind the magnetic induction coil 311, so as to facilitate the control of the circuit and have a smaller thickness.

[0065] Specifically, the driving device 3 is installed on the pump base 30, and the pump base 30 is detachably installed on the upper wall of the housing, which facilitates maintenance or replacement.

[0066] Specifically, the outer peripheral wall or the upper wall of the housing is provided with a clamping hole, and both sides of the pump base 30 are provided with hooks that cooperate with the clamping hole. The hooks can extend into the clamping hole and be hooked. Of course, the pump housing can also be fixed by screws, which facilitates installation.

[0067] Specifically, the impeller 2 includes blades 22 provided on the lower wall of the disk 21, and the blades 22 are spaced along the outer periphery of the disk 21 with the axis of the disk 21 as the center. The specific blades can be arc-shaped, strip-shaped or curved surface-shaped structures, so as to realize the flow of the fluid in a predetermined direction.

[0068] Specifically, the water chamber 1 is provided with a diversion seat 5, the diversion seat 5 is provided with a diversion channel, and the impeller 2 can drive the fluid to sequentially pass through the fluid inlet 11, the diversion channel, the diversion layer 40, and flow to the fluid outlet 12. By providing the diversion seat 5, the generation of turbulent flow can be reduced, the fluid can flow orderly, and the heat dissipation effect can be improved.

[0069] Specifically, the diversion channel includes two first flow channels 51 arranged at intervals and a second flow channel 52 provided on the bottom wall of the diversion seat 5. The first flow channels 51 penetrate through the diversion seat 5, and the lower ends of the first flow channels 51 are connected to the diversion layer 40. The fluid flows to the second flow channel 52 after passing through the diversion layer 40;

[0070] The upper wall of the diversion seat 5 is provided with a groove 53 that connects the two first flow channels 51. When the impeller 2 rotates, the fluid direction is generally from the axis to the outside, so as to realize the fluid pressure. Therefore, diversion channels are provided on both sides to flow from both ends of the diversion layer 40 to the middle, and finally flow to the fluid outlet 12 through the second flow channel 52 in the middle.

[0071] Specifically, the end of the diversion seat 5 is provided with a through groove 54, the through groove 54 is connected to the fluid outlet 12, and the second flow channel 52 is bent and extends through the through groove 54.

[0072] Specifically, a first rotating shaft 6 extends downward from the top wall of the inner cavity 10, and the first rotating shaft is used to install the impeller 2.

[0073] Specifically, a bearing is provided between the rotating shaft and the impeller 2, and the bearing can be a corrosion-resistant structure such as a ceramic bearing, so as to improve the use stability.

[0074] Specifically, the pump base 30 is provided with a pivoting part, and the pivoting part is used to install the rotor 32 to make it rotate. Of course, for the disk-shaped rotor 32, the pivoting part can also be a bearing provided outside the rotor 32; or a second rotating shaft provided in the middle of the rotor 32; or bearings provided on both the inside and outside of the device.

[0075] In an embodiment of the present utility model, the water chamber is provided with a through hole 7 extending into the inner cavity, and the through hole is detachably installed with a sensor 8; the sensor can detect the water temperature, water quality, fluid pressure and liquid level of the fluid in the inner cavity; the sensor is connected with a control device, and the control device is also connected with a driving device. The control device can control the rotation speed of the impeller according to the data of the sensor. The sensor is connected with the driving device through a wire. Since the driving device integrates a control board (i.e., the control device is arranged in the driving device), and at the same time the control device can also integrate a wireless transceiver, the driving device can be directly controlled without passing through a computer interface, and only the power supply of the water pump needs to be provided, reducing the wires that will be exposed outside. At the same time, the data of the sensor will participate in calculating the rotation speed strategy of the water pump.

[0076] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
