[0037] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0038] Reference is made below Figures 1-2 A split flow generating device 100 according to an embodiment of the present application is described below, which is used to drive liquid flow, and can rotate liquid, and can be a wave generating pump. The split flow generating device 100 can be applied to a liquid cooling system, a wave generating system, a heat conducting oil circulating system, etc. The split flow generating device 100 is used to drive liquid flow in the liquid cooling system, which can be used to cool objects.

[0039] As shown in Figure 1 and Figure 2 The split flow generating device 100 according to an embodiment of the present application includes a housing 10, a stator structure 20 and a rotor structure 30, and a flow generating paddle 40. The housing 10 defines a mounting cavity 11 and a mounting groove 12, which are separated and arranged. The mounting groove 12 has an open end 13 for communicating with an adapter. The stator structure 20 is arranged in the mounting cavity 11, and the rotor structure 30 is arranged in the mounting groove 12. The stator structure 20 and the rotor structure 30 are magnetically coupled to rotate the rotor structure 30. The flow generating paddle 40 is fixedly arranged on the rotor structure 30 to rotate synchronously with the rotor structure 30 when the rotor structure 30 rotates.

[0040] The split flow generating device 100 includes the housing 10, the stator structure 20, the rotor structure 30 and the flow generating paddle 40. The housing 10 defines the mounting cavity 11 and the mounting groove 12, which are separated and arranged. The mounting cavity 11 and the mounting groove 12 are not communicated, and the mounting cavity 11 is an independent cavity independent of the mounting groove 12. The mounting groove 12 is a groove independent of the mounting cavity 11. The mounting groove 12 can have an open end 13 for communicating with an adapter. The adapter can define a liquid storage space 202, and the open end 13 is communicated with the liquid storage space 202. The mounting groove 12 is communicated with the liquid storage space 202 through the open end 13, and the liquid in the liquid storage space 202 can flow into the mounting groove 12 through the open end 13 of the mounting groove 12. Further, the adapter can be formed with a communication hole 2011, and the open end 13 of the mounting groove 12 and the communication hole 2011 are arranged opposite to each other. The communication hole 2011 communicates the open end 13 of the mounting groove 12 and the liquid storage space 202.

[0041] The stator structure 20 is arranged in the mounting cavity 11, the rotor structure 30 is arranged in the mounting groove 12, the stator structure 20 and the rotor structure 30 are arranged separately, and the stator structure 20 and the rotor structure 30 are magnetically coupled to drive the rotor structure 30 to rotate. The principle of magnetic induction between the stator structure 20 and the rotor structure 30 is based on the law of electromagnetic induction. The rotating magnetic field generated by the stator structure 20 interacts with the current in the rotor structure 30 to generate an electromagnetic torque, thereby driving the rotor structure 30 to rotate.

[0042] The stator structure 20 mainly consists of a stator core and a stator winding. The stator core is usually made of silicon steel sheets to reduce eddy current loss. The stator winding is wound by multiple turns of wire and is divided into three-phase windings, namely U-phase, V-phase and W-phase. The rotating magnetic field is generated when three-phase alternating current passes through the stator winding, generating alternating magnetic flux in the stator core, which forms a rotating magnetic field in space.

[0043] The rotor structure 30 mainly consists of a rotor core and a conductor strip (usually made of good conductive materials such as aluminum and copper). The conductor strip is fixed to the rotor core. When the rotating magnetic field generated by the stator structure 20 passes through the rotor conductor strip, an induced electromotive force is generated in the conductor strip, which in turn generates an electric current. This current interacts with the rotating magnetic field to generate an electromagnetic torque.

[0044] The flow creating paddle 40 is fixed to the rotor structure 30. The rotor structure 30 can have a mounting shaft 31, and the flow creating paddle 40 can be fixed to the mounting shaft 31 by bolts or can be clamped to the mounting shaft 31. When the rotor structure 30 rotates, it can drive the flow creating paddle 40 to rotate synchronously. The flow creating paddle 40 can drive the liquid to flow when it rotates. The liquid is a cooling liquid, and the flow of the cooling liquid can improve the heat exchange efficiency of the liquid in the liquid storage space 202.

[0045] Specifically, when the split flow creating device 100 is in operation, the mounting groove 12 is in communication with the liquid storage space 202 through the open end 13, and the liquid in the liquid storage space 202 can flow into the mounting groove 12. The stator structure 20 is energized to drive the rotor structure 30 to rotate the flow creating paddle 40, thereby driving the liquid to flow. In this application, the stator structure 20 is arranged in the mounting cavity 11, and the wire harness connected to the stator structure 20 does not need to pass through the groove wall of the mounting groove 12. The groove wall of the mounting groove 12 does not need to be provided with a wire harness through hole. The wire harness through hole can be provided on other shell walls of the shell 10. Since the shell wall provided with the wire harness through hole is not in contact with the liquid, the sealing complexity of the wire harness through hole is reduced, the risk of the liquid flowing into the mounting cavity 11 through the wire harness through hole to corrode the stator structure 20 is reduced, and after the liquid flows into the mounting groove 12, the liquid in the mounting groove 12 will not leak into the mounting cavity 11, which can further reduce the risk of liquid corroding the stator structure 20, thereby prolonging the service life of the flow creating device.

[0046] Thus, by arranging the stator structure 20 and the rotor structure 30 in the mounting cavity 11 and the mounting groove 12 respectively, the stator structure 20 and the rotor structure 30 are arranged separately, when the separate flow generating device 100 is in operation, the mounting groove 12 has liquid, the stator structure 20 is located outside the liquid, and the rotor structure 30 is located inside the liquid, compared with the prior art, the sealing complexity of the wire harness through hole is reduced, the risk of liquid flowing into the inside of the mounting cavity 11 through the wire harness through hole to corrode the stator structure 20 is reduced, and the service life of the flow generating device is prolonged.

[0047] In some embodiments of the utility model, as shown in Figure 1 The shell 10 includes an outer shell 14 and an inner shell 15, the outer shell 14 is sleeved on the inner shell 15, a mounting cavity 11 is formed between the outer shell 14 and the inner shell 15, the inner shell 15 defines a mounting groove 12, and the inner shell 15 is configured as a non-metal shell.

[0048] The shell 10 can include an outer shell 14 and an inner shell 15, the outer shell 14 is sleeved on the outer side of the inner shell 15, and the outer shell 14 and the inner shell 15 jointly define a mounting cavity 11, so that the mounting cavity 11 is formed between the outer shell 14 and the inner shell 15. The mounting cavity 11 can be a closed cavity, or the mounting cavity 11 can be an unclosed cavity, and the application is described by taking the mounting cavity 11 as a closed cavity as an example. The inner shell 15 defines an open-ended mounting groove 12, and the inner shell 15 is a groove wall of the mounting groove 12. The inner shell 15 can include an inner shell side wall 151 and an inner shell end wall 152. The inner shell side wall 151 is annular, and the inner shell end wall 152 is arranged at one end of the inner shell side wall 151. The inner shell side wall 151 is arranged along the edge of the inner shell end wall 152, so that the inner shell side wall 151 and the inner shell end wall 152 jointly define an open-ended mounting groove 12.

[0049] The wire harness through hole can be arranged on the outer shell 14, the outer shell 14 is sleeved on the inner shell 15 and does not shield the open end 13 of the mounting groove 12. Further, the outer shell 14 can include an outer shell side wall 141, the outer shell side wall 141 is annular, the outer shell side wall 141 is sleeved outside the inner shell side wall 151, the outer shell side wall 141 and the inner shell side wall 151 are spaced apart, so that the mounting cavity 11 is formed between the outer shell side wall 141 and the inner shell side wall 151. Further, the outer shell 14 can further include a first outer shell end wall 142 and a second outer shell end wall 143, one end of the outer shell side wall 141 is provided with the first outer shell end wall 142, the first outer shell end wall 142 is arranged opposite to the inner shell end wall 152, the other end of the outer shell side wall 141 is provided with the second outer shell end wall 143, the second outer shell end wall 143 is annular and is arranged along the circumference of the inner shell end wall 152 around the inner shell end wall 152, and the second outer shell end wall 143 is connected between the outer shell side wall 141 and the inner shell side wall 151, so that the sealing performance of the mounting cavity 11 can be improved, the risk that substances outside the split flow generating device 100 enter the mounting cavity 11 is reduced, and the working reliability of the stator structure 20 is improved.

[0050] The inner shell 15 is configured as a non-metal shell, and can also be understood as a non-metal piece. As an example, the inner shell 15 can be a plastic piece. The inner shell 15 separates the stator structure 20 and the rotor structure 30, and the material of the inner shell 15 does not affect the magnetic induction cooperation between the stator structure 20 and the rotor structure 30, so that the rotor structure 30 can rotate normally, and the split flow generating device 100 can work reliably.

[0051] In some embodiments of the utility model, as shown in Figure 1 The stator structure 20 is annular and arranged along the circumference of the inner shell 15 around the inner shell 15, and the rotor structure 30 and the stator structure 20 are opposite along the radial direction of the split flow generating device 100.

[0052] The outer shell side wall 141 is annular, the inner shell side wall 151 is annular, the outer shell side wall 141 is sleeved outside the inner shell side wall 151, the outer shell side wall 141 and the inner shell side wall 151 are spaced apart, so that the annular mounting cavity 11 is formed between the outer shell side wall 141 and the inner shell side wall 151, and the mounting cavity 11 is arranged along the circumference of the inner shell 15 around the inner shell 15. The stator structure 20 is annular, after the stator structure 20 is installed in the mounting cavity 11, the stator structure 20 is arranged along the circumference of the inner shell 15 around the inner shell 15, and the rotor structure 30 and the stator structure 20 are opposite along the radial direction of the split flow generating device 100.

[0053] If the rotor structure 30 and the stator structure 20 are not arranged opposite along the radial direction of the split flow generator 100, when the stator structure 20 is powered, the magnetic induction cooperation between the stator structure 20 and the rotor structure 30 is unstable, which affects the working performance of the split flow generator 100. Therefore, by arranging the rotor structure 30 and the stator structure 20 opposite along the radial direction of the split flow generator 100, when the stator structure 20 is powered, the magnetic induction cooperation stability between the stator structure 20 and the rotor structure 30 is improved, the working performance of the split flow generator 100 is improved, and thus the working reliability of the split flow generator 100 is improved.

[0054] In some embodiments of the utility model, as shown in Figure 1 The split flow generator 100 further comprises a first fixing frame 50, the first fixing frame 50 is arranged in the mounting cavity 11 and fixedly connected with the shell 10, and the stator structure 20 is fixedly arranged on the first fixing frame 50.

[0055] The split flow generator 100 further comprises a first fixing frame 50, the first fixing frame 50 is arranged in the mounting cavity 11 and fixedly arranged on the shell 10, the first fixing frame 50 is located between the outer shell side wall 141 and the inner shell side wall 151, and the first fixing frame 50 is fixedly connected with at least one of the outer shell side wall 141 and the inner shell side wall 151. The first fixing frame 50 can be detachably arranged on the shell 10. The stator structure 20 is fixedly arranged on the first fixing frame 50, the stator structure 20 can be clamped on the first fixing frame 50, the stator structure 20 can be bolted on the first fixing frame 50, and after the stator structure 20 is arranged on the first fixing frame 50, the first fixing frame 50 can limit the movement of the stator structure 20, which is beneficial to improve the position stability of the stator structure 20 and make the position of the stator structure 20 more stable.

[0056] Further, the first fixing frame 50 can be a plate structure, the first fixing frame 50 can be an annular structure, and the first fixing frame 50 can be sleeved on the inner shell side wall 151. By arranging the first fixing frame 50 as an annular structure, the arrangement area of the first fixing frame 50 can be increased, thereby facilitating the increase of the contact area between the first fixing frame 50 and the stator structure 20, further improving the position stability of the stator structure 20, and making the position of the stator structure 20 more stable. The first fixing frame 50 and the stator structure 20 can be arranged along the depth direction of the mounting groove 12, the depth direction of the mounting groove 12 is parallel to the axial direction of the split flow generator 100, and by arranging the first fixing frame 50 and the stator structure 20 along the depth direction of the mounting groove 12, the sliding of the stator structure 20 along the axial direction of the split flow generator 100 can be prevented, thereby reducing the risk of misalignment between the stator structure 20 and the rotor structure 30 and arranging the rotor structure 30 opposite to the stator structure 20 along the radial direction of the split flow generator 100.

[0057] In some embodiments of the utility model, as shown in Figure 1 The rotor structure 30 has a mounting shaft 31, and the flow generating blade 40 is fixedly arranged on the mounting shaft 31.

[0058] The rotor structure 30 has a mounting shaft 31, and the flow generating blade 40 can be fixedly arranged on the mounting shaft 31 or can be clamped on the mounting shaft 31. When the rotor structure 30 rotates, the rotor structure 30 can drive the mounting shaft 31 and the flow generating blade 40 to rotate synchronously, and the flow generating blade 40 can drive the liquid to flow when rotating. The flow generating blade 40 and the mounting shaft 31 are both configured as alloy parts, which have high strength, high hardness and good corrosion resistance. Such a configuration is conducive to improving the corrosion resistance and wear resistance of the flow generating blade 40 and the mounting shaft 31, so that the flow generating blade 40 and the mounting shaft 31 can be used for long-term operation in the liquid, thereby prolonging the service life of the flow generating blade 40 and the mounting shaft 31.

[0059] The existing flow generating blade and mounting shaft are made of iron, which makes the flow generating blade 40 and the mounting shaft 31 heavy and causes additional burden on the separation type flow generating device 100, thereby shortening the service life of the separation type flow generating device 100.

[0060] At least one of the flow generating blade 40 and the mounting shaft 31 of the present application can be made of an alloy, for example, at least one of the flow generating blade 40 and the mounting shaft 31 can be made of a nickel-aluminum-copper alloy material, a nickel-aluminum alloy material, an aluminum-copper alloy material or the like. Compared with the prior art, the weight of the flow generating blade 40 and the mounting shaft 31 can be reduced, the vibration of the separation type flow generating device 100 during operation can be reduced, the load of the flow generating blade 40 and the mounting shaft 31 on the separation type flow generating device 100 can be effectively reduced, and the service life of the separation type flow generating device 100 can be prolonged.

[0061] In some embodiments of the utility model, the manufacturing material of the flow generating blade 40 is the same as that of the mounting shaft 31. The flow generating blade 40 and the mounting shaft 31 can be made of a nickel-aluminum-copper alloy material, a nickel-aluminum alloy material, an aluminum-copper alloy material or the like. If the manufacturing material of the flow generating blade 40 is different from that of the mounting shaft 31, the flow generating blade 40 and the mounting shaft 31 are not firmly welded, the connection between the flow generating blade 40 and the mounting shaft 31 is prone to cracking, and the flow generating blade 40 and the mounting shaft 31 need to be repaired multiple times. By using the same manufacturing material for the flow generating blade 40 and the mounting shaft 31, the flow generating blade 40 and the mounting shaft 31 can be firmly welded, the connection reliability of the flow generating blade 40 and the mounting shaft 31 can be improved, the risk of cracking at the connection between the flow generating blade 40 and the mounting shaft 31 can be reduced, the maintenance cost during long-term use can be reduced, and the instability problem of dissimilar metal welding is reduced.
