Description

Technical Field

[0001] The utility model relates to the field of utility models, and particularly relates to a liquid driving device for 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 operation for a long time.

[0003] In the existing integrated design of a water pump and a first chamber, in order to realize the driving of an impeller by a brushless motor, generally the rotor is 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 partition plate will protrude and extend into the first chamber, thereby realizing the impeller driving the fluid to flow. The corresponding problem is that the volume of the first chamber is large, and at the same time the thickness is also large. Moreover, since the partition plate of the stator extends into the first chamber, the volume of the first chamber will also decrease accordingly.

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

[0005] The main object of the utility model is to propose a liquid driving device for a computer, aiming to realize the integrated setting of a water pump and a first chamber, with a simple structure, and while ensuring the volume of the first chamber, reducing its overall volume.

[0006] To achieve the above object, the utility model proposes a liquid driving device for a computer, including:

[0007] A partition plate, with a first chamber and a second chamber on both sides of the partition plate, and the second chamber is used to accommodate liquid;

[0008] An impeller, pivotally installed in the second chamber, and the position of the impeller close to the partition plate is a disk extending radially;

[0009] A pump base, arranged in the first chamber, the pump base 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 at the side wall position of the stator, and the magnetic field of the stator and the rotor is axially tangent;

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

[0011] The beneficial effects of this design:

[0012] 1. The first chamber and the second chamber are separated independently by a partition plate, so that the liquid will not affect the electronic components of the driving device, ensuring the service life and stable use of the driving device. The partition plate is a planar structure;

[0013] 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 first chamber and the pump base is smaller, effectively improving the aesthetics of the computer water cooling structure;

[0014] 3. The structure is simpler. There is no need for a concave-convex structure between the first chamber and the second 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;

[0015] 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.

[0016] Among them, the direction of the pump base can be set vertically or radially, and both can achieve fluid drive;

[0017] Among them, this structure can be applied to the integrated structure of a water cooling pump or a water cooling row, thereby effectively reducing the volume of the computer water cooling structure;

[0018] 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;

[0019] Especially for some problems where the rotor may get stuck or move slowly when the output power is increased after the pump body is blocked (i.e., a larger torque needs to be output), the service life of the water pump is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Such as Figures 1 to 6As shown in the figure, a liquid driving device for a computer includes:

[0037] A partition 10, with a first chamber 11 and a second chamber 12 on both sides of the partition 10, and the second chamber 12 is used to hold liquid;

[0038] An impeller 2, pivotally installed in the second chamber 12, and a disk 21 extending radially is located at the position of the impeller 2 close to the partition 10;

[0039] A pump base 4, arranged in the first chamber 11, with a stator 31 fixedly installed on the pump base 4. The stator 31 is provided with a rotor 32 that cooperates with each other. The rotor 32 and the stator 31 are arranged radially, the rotor 32 is located on the side wall of the stator 31, and the magnetic fields of the stator 31 and the rotor 32 are axially tangent;

[0040] The rotor 32 is arranged on the disk 21 or the rotor 32 drives the disk 21 to rotate through an intermediate member.

[0041] Beneficial effects of this design:

[0042] 1. The first chamber 11 and the second chamber 12 are separated independently by the partition 10, so the liquid will not affect the electronic components of the driving device, ensuring the service life and stable use of the driving device;

[0043] 2. The stator 31 and the rotor 32 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 first chamber 11 and the pump base 4 is smaller, effectively improving the aesthetics of the computer water-cooling structure;

[0044] 3. The structure is simpler. There is no need for concave and convex structures between the first chamber 11 and the second chamber 12 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;

[0045] 4. Under the same output torque, rotational speed and power conditions, compared with a 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.

[0046] The direction of the pump base 4 can be set vertically or radially, both of which can achieve fluid driving;

[0047] This structure can be applied to an integrated water-cooling pump structure or an integrated water-cooling radiator structure, thereby effectively reducing the volume of the computer water-cooling structure.

[0048] Specifically, the stator 31 includes a bracket 311 and magnetic induction coils 312 spaced apart on the bracket 311. The magnetic induction direction of the magnetic induction coils 312 is axial. The rotor 32 is provided with a plurality of permanent magnets 320, and its structure can be referred to as an axial flux motor. By controlling the direction of the current, the rotation of the rotor 32 can be controlled.

[0049] In the first embodiment, when the permanent magnets 320 are arranged on the disc 21, the stator 31 directly drives the permanent magnets 320 and drives the impeller 2 to rotate. A partition 10 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 first chamber 11 and can dissipate heat sufficiently. In principle, the magnetic field of the permanent magnets 320 is stable, so the corresponding main damaged component is the stator 31 (i.e., the magnetic induction coil 312 part). Therefore, even if the cooling component is damaged, only the stator 31 needs to be replaced, effectively improving the convenience of maintenance.

[0050] The rotor 32 and the disc 21 are integrally injection molded, thereby effectively protecting the structure of the stator 31 and improving the stability of the permanent magnets 320.

[0051] In the embodiment of the present invention, the magnetic field projection areas of the stator 31 and the rotor 32 are the same, thereby ensuring the stability of the drive and avoiding the problem of magnetic field loss.

[0052] The permanent magnets 320 are distributed in a fan shape on the rotor 32. The permanent magnets 320 include an S pole and an N pole, and the S pole and the N pole are arranged adjacent to each other, thereby realizing the tangency of the magnetic fields.

[0053] The partition 10 is a planar structure.

[0054] In the second embodiment, the rotor 32 is pivotally installed between the stator 31 and the partition 10.

[0055] The rotor 32 is provided with a first magnetic member 321, and the first magnetic member 321 is the permanent magnet 320. The disc 21 is provided with a second magnetic member 322 that cooperates with the first magnetic member 321. The partition 10 is arranged between the rotor 32 and the disc 21. Generally, the rotor 32 will also be provided with structures such as an iron core for fixing the permanent magnets 320. When the permanent magnets 320 are integrally injection molded, the use of the iron core can also be reduced to fix its magnetic poles.

[0056] In the embodiment of the present invention, the driving device is installed on the pump base 4, and the pump base 4 is detachably installed on the wall surface of the partition.

[0057] The side wall of the partition board is provided with clamping holes, and the two sides of the pump base are provided with hooks that cooperate with the clamping holes. The hooks can extend into the clamping holes and hook, and of course, the pump shell can also be fixed by screws, which is convenient for installation.

[0058] In the embodiment of the present invention, the impeller 2 includes blades 22 provided on the side wall or the outer peripheral wall of the disc 21, and the blades 22 are circumferentially spaced apart around the axis of the disc 21. Specifically, the blades 22 can be arc-shaped, strip-shaped or curved surface-shaped structures, so as to realize the flow of fluid in a predetermined direction.

[0059] In the embodiment of the present invention, a first rotating shaft 51 extends from the side wall of the partition board 10 towards the first chamber 11, and the first rotating shaft 51 is used to install the impeller 2.

[0060] A bearing is provided between the first rotating shaft 51 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.

[0061] A bearing is provided between the first rotating shaft 51 and the impeller 2. The bearing can be a corrosion-resistant structure such as a ceramic bearing, so as to improve the use stability.

[0062] In the embodiment of the present invention, a pivoting portion 52 extends from the pump base or the partition board 10, and the pivoting portion 52 is used to install the rotor 32 to make it rotate. Of course, for the disc-shaped rotor 32, the pivoting portion 52 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.

[0063] In the embodiment of the present invention, the partition board 10 is provided with a through hole extending into the first chamber 11, and a sensor 6 is detachably installed in the through hole; the sensor 6 can detect the water temperature, water quality, fluid pressure and liquid level of the fluid in the inner cavity; the sensor 6 is connected with a control device, and the control device is also connected with a driving device, and the control device can control the rotation speed of the impeller 2 according to the data of the sensor 6.

[0064] The first rotating shaft 51 is provided on one side of the impeller 2 or on both sides of the impeller 2, so as to meet different requirements. Among them, the double-shaft structure can improve the service life and rotation concentricity of the impeller 2.
