Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled radiators, and particularly relates to an integrated water pump water-cooled radiator for a computer. Background Art

[0002] The existing computer heat exchanger, also known as a water-cooled radiator, realizes the heat exchange between the liquid and the outside through the cooperation of the pipe body and the radiator fins (or with the cooperation of a fan), and the heated liquid is passed through the radiator fins.

[0003] In the existing design, the water tank, the pipe body and the water pump are integrally designed. However, due to the large volume of the water pump, the volume of the corresponding water tank will be reduced. Then, in order to increase the volume of the water tank (i.e., to store more liquid), its overall structure is relatively complex. For example, in Chinese Patent CN202120467569.4, in order to realize the relative operation of the stator and the rotor, a concave-convex structure is designed, so that the impeller is located in the water chamber, avoiding the contact between the electronic components and the water chamber. However, the mold production cost is relatively high, and its thickness is relatively large, so its overall volume is also relatively large. Summary of the Invention

[0004] The main object of the utility model is to provide an integrated water pump water-cooled radiator for a computer, aiming to improve the structure of the water-cooled radiator, reduce the structure of the water pump, and have a smaller thickness. At the same time, it can ensure the predetermined volume of the water tank, and has a simple structure, effectively reducing the production cost.

[0005] To achieve the above object, the utility model provides an integrated water pump water-cooled radiator for a computer, including

[0006] A water tank, the water tank includes a first water tank and a second water tank, and a plurality of pipe bodies are arranged between the first water tank and the second water tank, and radiator fins are arranged between adjacent pipe bodies;

[0007] The first water tank is provided with at least two liquid chambers arranged at intervals, and the two liquid chambers are respectively connected with a water outlet and a water inlet;

[0008] An impeller, the impeller is pivotally installed in the liquid chamber, a partition is arranged at a position of the first water tank far from the pipe body, and a disk extending radially is arranged on the side wall of the impeller close to the partition;

[0009] A driving device, the driving device includes a stator arranged on the outer wall of the partition and a rotor cooperating with the stator, the rotor and the stator are arranged radially, the rotor is located on the side wall position of 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. When the impeller rotates, the impeller can drive the liquid to flow.

[0011] In actual work, one set or two sets of drives can be set, that is, installed in any one liquid chamber or drive devices are set in both liquid chambers;

[0012] When the impeller rotates, the liquid sequentially passes through the liquid inlet, the first liquid chamber, the pipe body, the second water tank, the second liquid chamber (the drive device is set at the position of the second liquid chamber, and of course both can be set. When both are set, the directions of the water outlet and the water inlet do not need to be considered) and the water outlet, thereby realizing the heat exchange of the heated liquid, and transporting the cooled liquid to the heating element through the water outlet, thereby realizing cooling;

[0013] 1. The outer walls of the liquid chamber and the first water tank are independent of each other, so the liquid will not affect the circuit elements, ensuring the service life and use safety of the drive device;

[0014] 2. The stator and the rotor are radially arranged, and then axially tangent, reducing the overall thickness of the drive device. At the same time, the first water tank and the water pump are integrally designed, making its structure simpler and the volume smaller, effectively improving the aesthetics of the computer water cooling structure;

[0015] 3. The structure is simpler. There is no need for a concave-convex structure between the water chamber and the pump chamber to realize the tangency of the stator and the rotor. A radial structure can be adopted, so the mold production cost is lower, effectively improving the market competitiveness;

[0016] 4. Under the same output torque, rotational speed and power conditions, compared with the radial flux motor, the axial flux motor (i.e., the drive 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.

[0017] The direction of the pump base can be vertically set or radially set, and the corresponding direction can also be changed accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The first water tank 11 is provided with at least two liquid chambers arranged at intervals, and the two liquid chambers are respectively connected to a water outlet 101 and a water inlet 102;

[0041] An impeller 2, the impeller 2 is pivotally installed in the liquid chamber, a partition 10 is provided at a position of the first water tank 11 away from the pipe body 61, and a radially extending disc 21 is provided on the side wall of the impeller 2 close to the partition 10;

[0042] A driving device 3, the driving device 3 includes a stator 31 provided on the outer wall of the partition 10 and a rotor 32 cooperating with the stator 31, the rotor 32 and the stator 31 are radially arranged, the rotor 32 is located on the side wall position of the stator 31, and the magnetic fields of the stator 31 and the rotor 32 are axially tangent;

[0043] The rotor 32 is provided on the disc 21 or the rotor 32 drives the disc 21 to rotate through an intermediate member. When the impeller 2 rotates, the impeller 2 can drive the liquid to flow.

[0044] In actual work, one set or two sets of drives can be provided, that is, installed in any one liquid chamber or driving devices 3 are provided in both liquid chambers;

[0045] When the impeller 2 rotates, the liquid sequentially passes through the liquid inlet, the first liquid chamber 111, the pipe body 61, the second water tank 12, the second liquid chamber 112 (the driving device 3 is arranged at the position of the second liquid chamber 112) and the water outlet, thereby realizing the heat exchange of the heated liquid, and conveying the cooled liquid to the heating element through the water outlet, thereby realizing cooling;

[0046] 1. The outer wall of the liquid chamber and the first water tank 11 are independent of each other, so the liquid will not affect the circuit components, ensuring the service life and safety of the driving device 3;

[0047] 2. The stator 31 and the rotor 32 are radially arranged to achieve axial tangency, thereby reducing the overall thickness of the drive device 3. At the same time, the first water tank 11 and the water pump are designed as one body, making the structure simpler and the volume smaller, which effectively improves the aesthetics of the computer water cooling structure;

[0048] 3. The structure is simpler. There is no need for a concave-convex structure between the water chamber and the pump chamber to achieve tangency between the stator 31 and the rotor 32. A radial structure is sufficient. Therefore, the mold production cost is lower, which effectively improves market competitiveness.

[0049] 4. Under the same output torque, speed and power, the axial flux motor (i.e., the drive device 3 of the present application) is compared with the radial flux motor: 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 maneuverability of the equipment and achieve lightweight.

[0050] The direction of the pump seat can be vertical or radial, and the corresponding direction can also be changed accordingly.

[0051] Specifically, the stator 31 includes a bracket 311 and a magnetic induction coil 312 spaced apart from the bracket 311, and the magnetic induction direction of the magnetic induction coil 312 is axial;

[0052] The rotor 32 is provided with a plurality of permanent magnets 320 , and its structure can be referred to as an axial flux motor. The rotation of the rotor 32 is controlled by controlling the direction of the current.

[0053] In the first embodiment, when the permanent magnet 320 is arranged on the disc 21, the stator 31 directly drives the permanent magnet 320 and drives the impeller 2 to rotate, and the 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 liquid chamber, which can fully dissipate heat. In principle, the magnetic field of the permanent magnet 320 is stable, and the corresponding main damaged element is the stator 31 (that is, the magnetic induction coil 312 part). Therefore, even if the cooling component is damaged, the stator 31 can be replaced, which effectively improves the convenience of maintenance; the rotor 32 and the disc 21 are integrally injection molded, thereby effectively protecting the stator 31 structure and improving the stability of the permanent magnet 320.

Generally, the rotor 32 will also be provided with a core and other structures for fixing the permanent magnets 320. When the permanent magnets 320 are integrally injection-molded, the use of the core can also be reduced and its magnetic poles can be fixed.

[0056] Specifically, the drive device 3 is a single module. The drive device 3 is installed on the outer wall of the partition 10, which facilitates the maintenance of the drive device 3. Among them, the permanent magnets 320 of the impeller 2 will generally not be damaged in principle. Therefore, the rotation of the impeller 2 can be achieved by replacing the drive device 3.

[0065] Specifically, the water inlet and outlet are provided at the upper wall position and / or the side wall position of the first water tank 11.

[0066] Specifically, the second liquid chamber 112 is not provided with the driving device 3.

The partition 10 is provided with a filter layer, and the filter layer can filter the impurities generated by the copper-aluminum reaction in the liquid, and will not completely accumulate in the water channel, thus causing the performance degradation problem caused by blocking the water channel.

[0067] At the same time, it can also filter the impurities when injecting the liquid, effectively improving the flow smoothness of the fluid.

[0068] Specifically, the bracket 311 is a PCB board or an iron core, and the magnetic induction coil 312 is arranged on the PCB board.

[0069] In actual design, it is preferred to wind the magnetic induction coil 312 on the PCB board, which is convenient for circuit control and has a smaller thickness.

[0070] Specifically, when it is a PCB board, a groove 51 is provided on the side wall of the first water tank 11, the PCB board is arranged in the groove 51, and a rear cover 52 (i.e., the pump housing) is also provided on the side of the groove 51 away from the PCB board. This is convenient for the installation of the stator 31, and can be set to a structure suitable for the length of the first water tank 11 or a structure that matches the first liquid chamber 111 according to actual needs, thereby realizing the modular production of the driving device 3.
