In addition, the water-cooling pipe can be squeezed during water-cooling heat dissipation to increase the heat dissipation area, thereby further improving the heat dissipation efficiency. In addition, through the pushing block and the rotating disk, in the process of the extruding strips approaching the water-cooling pipe, the rotating disk is driven to rotate slightly, thereby adjusting the water-cooling pipe spirally wrapped around the surface of the stator component to a synchronous rotation state, realizing adjustment of the water-cooling area, and closing the electromagnetic plate when the extruding strips start to squeeze the water-cooling pipe to stop the pushing effect of the pushing block on the rotating disk, so that the extruding water-cooling pipe and the rotating adjustment water-cooling pipe are in an intermittent switching state, thereby comprehensively improving the overall heat dissipation efficiency. Finally, the pushing degree of the rotating disk by the pushing block each time can be randomly adjusted to avoid heat dissipation omissions.

[0001] The present invention relates to a heat dissipation integrated motor, and in particular to a high-efficiency heat dissipation integrated motor applied in the field of motor heat dissipation. Background Art

[0002] During motor operation, due to imperfect energy conversion efficiency, some electrical energy is converted into heat, causing the motor's internal temperature to rise. If this heat is not dissipated promptly and effectively, the motor's temperature will continue to rise, affecting its performance and lifespan. With the continuous development of motor technology and the growing demand for its application, motor cooling technology will also continue to innovate and improve.

[0003] The specification of Chinese invention patent CN118282132B discloses a high-efficiency heat dissipation treatment device for a permanent magnet synchronous motor, which has high-efficiency airflow heat dissipation function and liquid circulation heat conduction heat dissipation function, achieving a circulating heat dissipation effect. By setting the gap and coordinating the airflow heat dissipation effect, the airflow circulation efficiency is greatly improved, thereby further achieving the improvement of heat dissipation efficiency, and can achieve the effect of improving the liquid heat dissipation efficiency, thereby improving the liquid circulation cooling efficiency.

[0004] Existing motor cooling equipment generally uses a combination of air cooling and water cooling to achieve efficient heat dissipation. However, during the heat dissipation process, the water cooling pipe is fixedly spirally arranged inside the motor, and the cooling contact area is limited and fixed, making it difficult to achieve uniform and comprehensive heat dissipation. As a result, the motor suffers from insufficient heat dissipation. Summary of the Invention

[0005] In view of the above-mentioned existing technology, the technical problem to be solved by the present invention is how to provide an adjustable method to make the water cooling pipe in dynamic change during the heat dissipation process of the motor, so that the water cooling pipe can provide uniform and comprehensive heat dissipation service for the inside of the motor.

[0007] The tail end of the pull rope is connected to a traction block, the bottom of the traction block is connected to an extruded strip located on the outside of the water-cooling pipe, the internal rotation of the motor housing is connected to a rotating disk located below the water-cooling pipe, and the top of the rotating disk is connected to the tail end of the water-cooling pipe through a telescopic block, the bottom of the extruded strip is installed with a block located above the rotating disk, the surface of the block is connected to a pushing block located on the outside of the rotating disk through an L-shaped support rod, an electromagnetic plate is installed inside the pushing block, and the surface of the electromagnetic plate close to the rotating disk is connected to a magnetic push plate that repel each other with the electromagnetic plate through an elastic strip.

[0008] In the above-mentioned high-efficiency heat dissipation integrated motor, on the basis of providing a combined heat dissipation method of air cooling and water cooling, it is also possible to squeeze the water-cooling tube during water-cooling heat dissipation to increase the heat dissipation area. In the process of squeezing the slats close to the water-cooling tube, the rotating ring disk is driven to rotate slightly, thereby realizing the adjustment of the water-cooling area.

[0009] As a further improvement of the present application, the water cooling pipe is made of a heat-conducting elastic memory material, and the water cooling pipe is in close contact with the surface of the stator component.

[0010] As a further improvement of the present application, the surface of the magnetic push plate coincides with the tangent of the quarter point of the surface of the rotating ring disk when the electromagnetic plate is started, the surface of the magnetic push plate is in a non-contact state with the surface of the rotating ring disk when the electromagnetic plate is not started, and the surface of the magnetic push plate close to the rotating ring disk is made of rubber material.

[0015] As another improved supplement of the present application, when the multiple electromagnetic plates in the push block are started, the electromagnetic blocks in the started state are adjacent to each other in sequence, and the number of the electromagnetic blocks in the started state is random.

[0016] To sum up, the rotating shaft is used to drive the fan to rotate and cooperate with the water-cooling pipe to provide a combination of air cooling and water cooling for the motor. In addition, the water-cooling pipe can be squeezed during water-cooling to increase the heat dissipation area and further improve the heat dissipation efficiency. In the process of the extruding strips approaching the water-cooling pipe, the rotating disk is driven to rotate slightly to adjust the water-cooling pipe and adjust the water-cooling area. When the extruding strips begin to squeeze the water-cooling pipe, the electromagnetic plate is turned off to stop the pushing effect of the pushing block on the rotating disk, so that the squeezing of the water-cooling pipe and the rotating adjustment of the water-cooling pipe are in an intermittent switching state, thereby comprehensively improving the overall heat dissipation efficiency. Finally, the degree of push of the pushing block on the rotating disk each time can be randomly adjusted to avoid heat dissipation omissions. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figure 1-7 The present invention shows an efficient heat dissipation integrated motor, comprising a heat dissipation shell 2 installed on the top of a motor housing 1, and a plurality of heat dissipation openings are provided on the top of the heat dissipation shell 2. A pulse-controlled rotating shaft 3 and a stator component 4 located on the outside of the rotating shaft 3 are installed inside the motor housing 1. A rotor component 5 located on the inside of the stator component 4 is fixedly installed on the outer surface of the rotating shaft 3. A water-cooling pipe 6 spirally wrapped around the outer surface of the stator component 4 is installed inside the motor housing 1. One end of the rotating shaft 3 extends to the inside of the heat dissipation shell 2 and is installed with a small reducer 8. A fan 7 is sleeved on the surface of the rotating shaft 3 located inside the heat dissipation shell 2. The output end of the small reducer 8 is connected to a driving shaft 9. Both sides of the driving shaft 9 are connected to symmetrically arranged lead screws 10 through a bevel gear set 11. The surface of each lead screw 10 is threadedly connected to a moving block, and the surface of the moving block is connected to a cable 15 extending into the motor housing 1.

[0032] The tail end of the pulling rope 15 is connected to the traction block 13, and the bottom of the traction block 13 is connected to the extrusion strip 14 located on the outside of the water-cooling pipe 6. The internal rotation of the motor housing 1 is connected to the rotating disk 17 located below the water-cooling pipe 6, and the top of the rotating disk 17 is connected to the tail end of the water-cooling pipe 6 through the telescopic block 19. The bottom of the extrusion strip 14 is installed with a block located above the rotating disk 17, and the surface of the block is connected to the pushing block 18 located on the outside of the rotating disk 17 through an L-shaped support rod. The inside of the pushing block 18 is installed with an electromagnetic plate 181, and the surface of the electromagnetic plate 181 close to the rotating disk 17 is connected to a magnetic push plate 182 that repel each other with the electromagnetic plate 181 through an elastic strip.

[0033] When the electromagnetic plate 181 is in the activated state, the surface of the magnetic push plate 182 coincides with the tangent of the quarter point of the surface of the rotating ring disk 17. When the electromagnetic plate 181 is not activated, the surface of the magnetic push plate 182 is in a non-contact state with the surface of the rotating ring disk 17, and the surface of the magnetic push plate 182 close to the rotating ring disk 17 is made of rubber material.

[0034] Specifically, in the present application, pulse control can be used to precisely control the rotation angle and speed of the motor, so that the rotation speed can be reduced when the motor overheats, thereby reducing the heat dissipation requirements.

[0035] During heat dissipation, the fan 7 in the heat dissipation housing 2 can achieve air cooling by rotating the shaft 3 (because the heat dissipation housing 2 is connected to the inside of the motor housing 1, gas circulation can be achieved between the two), and provide heat dissipation services for the surface of the stator component 4 through the water cooling pipe 6 with built-in coolant.

[0036] When the rotating shaft 3 rotates, it can drive the driving shaft 9 to rotate at a low speed (because the use of a small reducer 8 between the two can avoid the rapid movement of the moving block on the surface of the screw 10), thereby driving the pull rope 15 to adjust slowly, thereby driving the traction block 13 to gradually approach the direction of the water-cooling pipe 6, and then driving the extrusion strips 14 to gradually squeeze the water-cooling pipe 6, thereby increasing the contact area between the water-cooling pipe 6 and the surface of the stator component 4, thereby improving the heat dissipation efficiency.

[0037] Figure 8 As shown, in the process of squeezing the slats 14 close to the water-cooling pipe 6, the support rod, driven by the block, will make the pushing block 18 close to the rotating disk 17. At this time, the electromagnetic plate 181 in the pushing block 18 is activated, so that the magnetic push plate 182 gradually approaches the surface of the rotating disk 17 and moves to the quarter point position of the rotating disk 17, which has a pushing effect, causing the rotating disk 17 to be in a small rotation state, thereby driving the water-cooling pipe 6 to have a small rotation displacement on the surface of the stator component 4, adjusting the contact area with the stator component 4 (because the water-cooling pipe 6 and the surface of the stator component 4 are threaded, the contact area will change during rotation), thereby achieving the effect of supplementary heat dissipation in different areas.

[0038] When the extrusion strip 14 moves to the position where it starts to squeeze the water-cooling tube 6, the electromagnetic plate 181 is powered off. At this time, the adjustment state of the water-cooling tube 6 is synchronously terminated to allow for extrusion to increase the heat dissipation area. At the same time, in the subsequent process of the extrusion strip 14 moving away from the water-cooling tube 6, the pushing block 18 will not push and rotate the rotating ring disk 17 when it resets, so that the adjusted state of the water-cooling tube 6 can be maintained.

[0039] The water cooling tube 6 is made of a heat-conducting elastic memory material, and the water cooling tube 6 is in close contact with the surface of the stator component 4 .

[0040] Specifically, since the water cooling tube 6 is in close contact with the stator component 4, it will not affect the rotation adjustment of the water cooling tube 6. In addition, the material of the water cooling tube 6 enables it to maintain a spiral winding state without being constrained by the surface connection with the stator component 4.

[0041] A displacement sensor is installed inside the pushing block 18 , and the displacement sensor is connected to the electromagnetic plate 181 for signal communication.

[0042] Specifically, the displacement sensor can be used to monitor the movement direction and displacement distance of the push block 18, so as to control the start-up state of the electromagnetic plate 181. When the movement direction is close to the rotating ring disk 17, the electromagnetic plate 181 is started. When the displacement distance reaches the extrusion strip 14 and starts to squeeze the water-cooling tube 6, the electromagnetic plate 181 is closed. When the movement direction is away from the rotating ring disk 17, the electromagnetic plate 181 is also closed.

[0043] Figure 2 and Figure 4 It is shown that multiple guide wheels 16 are installed inside the motor housing 1 and the heat dissipation shell 2, and the ropes 15 are respectively connected to the surfaces of the guide wheels 16. The lowest guide wheel 16 in the motor housing 1 is located above the extruded slats 14, and the vertical projection of the lowest guide wheel 16 in the motor housing 1 coincides with the vertical projection of the water-cooling pipe 6.

[0044] Specifically, the guide wheel 16 is installed to adjust the direction of the cable 15 so that the cable 15 can drive the traction block 13 to approach the water-cooling pipe 6 and drive the extrusion strip 14 to squeeze the water-cooling pipe 6 when following the movement and adjustment of the moving block.

[0045] Figure 2 and Figure 4 As shown, a plurality of spring members 12 are installed on the inner wall of the motor housing 1 , and each spring member 12 is connected to the pulling block 13 and the surface of the block respectively.

[0046] Specifically, the design of the spring member 12 is used to facilitate the resetting of the traction block 13 and the block, thereby providing operational support for the periodic squeezing of the water-cooling tube 6 .

[0047] Second implementation method:

[0048] Figure 9 The replacement structure of the electromagnetic plate 181 is shown to be a plurality of adjacent contacting electromagnetic blocks 183, and the replacement structure of the magnetic push plate 182 is a plurality of adjacent contacting magnetic push blocks 184, and a return spring is connected between each electromagnetic block 183 and magnetic push block 184.

[0049] When the plurality of electromagnetic blocks 183 in the push block 18 are started, the electromagnetic blocks 183 in the started state are adjacent to each other in sequence, and the number of electromagnetic plates 181 in the started state is random.

[0050] The difference from the first embodiment is that in the first embodiment, the pushing block 18 moves the same distance each time, resulting in the water-cooling tube 6 rotating and adjusting the same distance each time. When the subsequent extrusion strips 14 squeeze the water-cooling tube 6 multiple times, the extrusion positions on the surface of the water-cooling tube 6 overlap, resulting in heat dissipation omissions, and improvements are made for this purpose.

[0051] Specifically, Figure 10 As shown, a corresponding number of electromagnetic blocks 183 are randomly selected to start each time, and the selected electromagnetic blocks 183 are in an adjacent state (that is, there is no intermediate discontinuity. For example, there are five electromagnetic blocks 183, labeled one, two, three, four, and five. Similarly, three electromagnetic blocks 183 are selected to start. The combination can be labeled one, two, three, three, four, and two, three, four, but not one, two, four, one, two, five, and two, three, five). In this way, the degree of pushing the rotating disk 17 each time the pushing block 18 moves can be controlled, thereby controlling the rotation amplitude of the water-cooling tube 6 each time (because the displacement distance of the pushing block 18 each time is fixed, and the rotation amplitude of the pushing rotating disk 17 is controlled by adjusting the actual length of the magnetic push plate 182).

[0052] In summary, the present application utilizes the rotating shaft 3 to drive the fan 7 to rotate and cooperate with the water-cooling pipe 6 to provide a combination of air cooling and water cooling for the motor. In addition, the screw 10, the extrusion strip 14 and the pull rope 15 cooperate to squeeze the water-cooling pipe 6 during water cooling to increase the heat dissipation area and further improve the heat dissipation efficiency. In addition, through the pushing block 18 and the rotating disk 17, when the extrusion strip 14 approaches the water-cooling pipe 6, the rotating disk 17 is driven to rotate slightly, thereby adjusting the water-cooling pipe 6 spirally wrapped around the surface of the stator 4 to a synchronous rotation state, thereby achieving adjustment of the water-cooling area, and when the extrusion strip 14 begins to squeeze the water-cooling pipe 6, the electromagnetic plate 181 is closed to stop the pushing effect of the pushing block 18 on the rotating disk 17, so that the squeezing of the water-cooling pipe 6 and the rotation adjustment of the water-cooling pipe 6 are in an intermittent switching state, thereby comprehensively improving the overall heat dissipation efficiency. Finally, through the design of the electromagnetic block 183 and the magnetic push block 184, the degree of pushing of the rotating disk 17 by the pushing block 18 each time can be randomly adjusted to avoid heat dissipation omissions.

[0053] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
