[0002] The motor is affected by various losses during operation, and the heat problem has always been a key and difficult issue in the design and development process. The higher the stator temperature of the motor, the greater the loss under the same current, the lower the electromagnetic performance, and it may even be unable to operate for a long time.

[0003] In the prior art, cooling is achieved by opening holes in the casing to increase airflow, or by installing water-cooling pipes to dissipate heat. However, when dissipating heat through water-cooling pipes, the coolant also needs to be driven by an additional water pump, which makes the structure of the motor more redundant. When an abnormality or damage occurs, it is inconvenient to repair or replace it.

[0004] Therefore, the present invention proposes a motor cooling structure and a motor to improve this problem. Summary of the Invention

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1-9 As shown, an embodiment of the present invention provides a motor cooling structure, including a rotor 3, which is a motor rotor in the prior art and consists of a rotor core and a magnet, and further includes: The mounting shell 1 has a rotating rod 101 connected to the rotor 3 rotatably mounted thereon. The rotating rod 101 is coaxially connected to the rotor 3. When the rotor 3 rotates, the rotating rod 101 can be driven to rotate. A first bevel gear 102 is mounted on the rotating rod 101. A driving rod 103 is rotatably mounted in the mounting shell 1. A second bevel gear 104 meshing with the first bevel gear 102 is mounted on the driving rod 103. Since the first bevel gear 102 is meshed with the second bevel gear 104, when the rotating rod 101 rotates, the driving rod 103 can be driven to rotate. When the device is in use, the mounting shell 1 is used to be connected to the motor; There are two cooling shells 2 and they are symmetrically mounted on the side walls of the mounting shell 1. A connecting pipe 201 is mounted on the cooling shell 2. The connecting pipe 201 is used to connect the two cooling shells 2. Coolant is provided in the cooling shell 2. The connecting pipe 201 and the cooling shell 2 form a frame-shaped structure, so that the coolant in the cooling shell 2 can flow in the inner cavity of the frame-shaped structure. When the device needs to be used, the connecting pipe 201 and the cooling shell 2 enclose the motor. The coolant is the existing technology, mostly deionized water or a water-ethylene glycol mixture. When the motor is in use, heat is generated. The coolant in the cooling shell 2 is heat exchanged with the motor by heat exchange, thereby dissipating heat and cooling the motor. One end of the driving rod 103 rotates and penetrates the mounting shell 1 and the cooling shell 2. The end of the driving rod 103 penetrates the mounting shell 1 and is located on the outside, and a sealed bearing is installed on the cooling shell 2. The end of the driving rod 103 is inserted in the sealed bearing, so that the end of the driving rod 103 can be located inside the cooling shell 2 and can rotate. A rotating wheel 202 is rotatably installed on one end of the driving rod 103 located inside the cooling shell 2. Fan blades 203 for stirring the coolant are installed on the circumference of the rotating wheel 202. There are multiple fan blades 203 on the circumference of the rotating wheel 202. When the rotating wheel 202 rotates, the fan blades 203 are driven to rotate in the cooling shell 2, which plays a role in stirring the coolant, thereby increasing the fluidity of the coolant in the cooling shell 2 and the connecting pipe 201, further increasing the heat dissipation effect of the device on the motor, and the structure of the device for stirring the coolant is relatively simple, which is convenient for subsequent maintenance. The device drives the fan blades 203 only by mechanical conduction, which reduces energy consumption and plays an energy-saving and environmentally friendly role compared to using a water pump; Compared with the prior art, a rotating rod 101 is installed in the mounting shell 1, and the rotating rod 101 is connected to the rotor 3. The rotating rod 101 can drive the driving rod 103 to rotate through the transmission of the first bevel gear 102 and the second bevel gear 104, and the driving rod 103 is located on one end of the cooling shell 2 and is equipped with a fan blade 203, so that when the rotor 3 rotates, the driving rod 103 and the fan blade 203 can be driven to rotate through the rotating rod 101, and the coolant in the cooling shell 2 can be moved by the fan blade 203, thereby increasing the fluidity of the coolant. When in use, while increasing the fluidity of the coolant, the structure of the device is also relatively simple, which is convenient for maintenance and replacement.

[0020] like Figure 1 and Figure 3 As shown, a partial structure of the cooling shell 2 is disclosed. The cooling shell 2 is rotatably mounted on the mounting shell 1. The connecting pipe 201 is made of iron or other hard materials. A support block 4 is slidably mounted on the mounting shell 1. A limiting member 5 for limiting the rotation of the cooling shell 2 is installed on the mounting shell 1. The limiting member 5 can limit the sliding of the support block 4. When the cooling shell 2 rotates, the position of the connecting pipe 201 is lower than the position of the bottom of the mounting shell 1. When the device is not in use, the bottom of the support block 4 is on the same plane as the bottom of the mounting shell 1 and the position of the cooling shell 2 is located at Figure 1 The position in the middle is not tilted. When the device is put into use, the cooling shell 2 is rotated to be in a tilted position, resulting in the position of the connecting pipe 201 being lower than the bottom of the mounting shell 1, and then the support block 4 is slid, so that the support block 4 and the connecting pipe 201 act as a bracket, and the position of the mounting shell 1 is raised, so that the device can lift the motor. Compared with placing the motor on the ground or a work plane, the area of ​​the motor surface in contact with the outside world is increased, and the possibility of heat accumulation at the bottom of the motor is reduced, thereby facilitating better heat dissipation of the motor and increasing the cooling effect of the device.

[0021] like Figure 2 and Figure 7, the specific structure of the limiting member 5 is disclosed. The limiting member 5 includes a first limiting plate 501 and a second limiting plate 502 installed on the installation shell 1. A round block is installed on the installation shell 1, and a block is installed on the cooling shell 2. A rotating cavity for accommodating the round block is opened on the block. The distribution positions of the first limiting plate 501 and the second limiting plate 502 are as shown in Figure 7. A first moving plate 503 and a second moving plate 504 are installed on the cooling shell 2. The second moving plate 504 and the first moving plate 503 are installed on the above-mentioned block of the cooling shell 2. Insertion holes 505 are opened on the first limiting plate 501, the second limiting plate 502, the first moving plate 503 and the second moving plate 504. An insertion rod 506 for inserting into the insertion hole 505 is installed on the installation shell 1. The insertion rod 506 is in a U shape. When the device does not need to be supported, the first limiting plate 501 contacts the first moving plate 503, and the insertion holes 505 on the two are aligned. At this time, when the insertion rod 506 is inserted into the insertion hole 505, the side wall of the insertion rod 506 blocks the inner wall of the insertion hole 505, and the rotation of the cooling shell 2 is restricted. At this time, the cooling shell 2 is in the Figure 1 position in. When it is necessary to support the motor, pull out the insertion rod 506 from the insertion hole 505, rotate the cooling shell 2 so that the second moving plate 504 rotates to contact the second limiting plate 502, and after the insertion holes 505 on the two are aligned, insert the insertion rod 506 into the insertion hole 505. At this time, the cooling shell 2 is in an inclined state, so that the connecting pipe 201 can support the installation shell 1; An extension plate 507 is slidably installed on the installation shell 1. The extension plate 507 is connected to the support block 4 and is located below the second limiting plate 502. The insertion rod 506 is provided with a hole for inserting a bolt. A block is installed on the installation shell 1 and a threaded hole for threadedly connecting the bolt is opened on the block. When the insertion rod 506 is inserted into the insertion hole 506 on the second moving plate 504 and then continues to be inserted downward, it will push the extension plate 507 and at the same time lift the motor upward to play a boosting role. At this time, the extension plate 507 and the support block 4 are顶住 by the insertion rod 505 and cannot move upward. When the support block 4 slides to the maximum extent on the installation shell 1, insert a bolt into the insertion rod 506 and make the bolt threadedly connected to the block to limit the displacement of the insertion rod 505 in the insertion hole 506. While restricting the rotation of the cooling shell 2, it also restricts the sliding of the support block 4, making the device more stable when supporting the motor and increasing the practicability of the device.

[0022] As Figure 1 and Figure 5As shown, part of the structure on the connecting pipe 201 is disclosed. A plurality of auxiliary pipes 7 are installed on the connecting pipe 201 through a hose 6. The auxiliary pipes 7 are connected by an arc pipe 8. The total content of the coolant in the device is increased by the auxiliary pipes 7 and the arc pipe 8, and the contact area between the device and the motor is increased by the auxiliary pipes 7 and the arc pipe 8, thereby further increasing the cooling effect of the device. The auxiliary pipes 7 are connected to the connecting pipe 201 through the hose 6, thereby making.

[0023] like Figure 8 As shown, part of the structure of the rotating wheel 202 and the cooling shell 2 is disclosed. A driving roller 9 is coaxially installed on the rotating wheel 202, and a driven roller 10 is rotatably installed in the cooling shell 2. A moving belt 11 is sleeved between the driving roller 9 and the driven roller 10, and a toggle plate 12 is installed on the moving belt 11. When the rotating wheel 202 rotates, it drives the driving roller 9 to rotate. The driving roller 9 and the driven roller 10 are used to support the inner wall of the moving belt 11 to form a structure similar to a conveyor belt. When the driving roller 9 rotates, it drives the moving belt 11 to rotate, and then the moving belt 11 drives the toggle plate 12 to move in the cooling shell 2. The coolant is toggled by the movement of the toggle plate 12, which further increases the fluidity of the coolant in the cooling shell 2 and increases the cooling effect of the device.

[0024] like Figure 4 As shown, part of the structure inside the mounting shell 1 is disclosed. A rotating shaft 13 is rotatably mounted on the mounting shell 1. The rotating shaft 13 and the rotating rod 101 are connected to each other through a pulley assembly 14. Rotating blades 15 are mounted on the rotating shaft 13. An air outlet 16 is provided on the mounting shell 1. The pulley assembly 14 includes two pulleys and a belt, one of which is mounted on the rotating shaft 13, and the other pulley is mounted on the rotating rod 101. The belt is sleeved on the outside of the two pulleys. When the rotor 3 rotates and drives the rotating rod 101 to rotate, the rotating shaft 13 is also rotated through the transmission of the pulley assembly 14, and the rotating blades 15 are driven to rotate together, so that airflow is generated in the mounting shell 1, and the airflow can be exchanged with the outside air through the air outlet 16, thereby increasing the flow of airflow in the mounting shell 1 and thereby increasing the heat dissipation effect of the device.

[0025] like Figure 3 As shown, part of the structure inside the mounting shell 1 is disclosed. An air duct 17 is installed inside the mounting shell 1. One end of the air duct 17 is used to accommodate the rotating blades 15, and the other end is directed to the air outlet 16. The air outlet 16 is opened at the top of the mounting shell 1. The air duct 17 is L-shaped. Figure 1From the main perspective, one section is in the horizontal direction, and the port of this section is used to accommodate the rotating blade 15. The other section is in the vertical direction, and its end faces the air outlet 16 but there is a gap between it and the air outlet 16. The airflow generated by the rotating blade 15 guided by the air guide 17 can be directed toward the air outlet 16 located at the top of the mounting shell 1. When the airflow passes through the gap between the air guide 17 and the air outlet 16, it can drive the airflow at other positions in the mounting shell 1 to move toward the air outlet 16, further increasing the heat dissipation effect of the device.

[0026] like Figure 6 and Figure 11 As shown, part of the structure on the mounting shell 1 is disclosed. The mounting shell 1 is provided with a baffle plate 18 at the air outlet 16. There is a gap between the baffle plate 18 and the air outlet 16 for air flow to pass through. The projection of the baffle plate 18 on the mounting shell 1 coincides with the air outlet 16. The baffle plate 18 is located above the air outlet 16. When the device is in use, the air flow blown out by the rotating blades 15 in the mounting shell 1 can flow to the outside of the mounting shell 1 through the gap between the baffle plate 18 and the air outlet 16. By arranging the baffle plate 18 above the air outlet 16, the possibility of external dust falling into the mounting shell 1 by gravity is reduced, thereby increasing the practicality of the device.

[0027] like Figure 10-12 As shown, the present invention also provides a motor, which in some embodiments includes any of the above-mentioned motor cooling structures, and also includes a motor housing 19. The rotor 3 is rotatably mounted on the motor housing 19. A stator 20 is installed in the motor housing 19. The stator 20 is the stator 20 in the motor in the prior art and is used in conjunction with the rotor 3. A cavity 21 for accommodating the auxiliary pipe 7 and the arc pipe 8 is opened on the wall thickness of the motor housing 19. The auxiliary pipe 7 and the arc pipe 8 are both installed in the cavity 21, so that the coolant in the auxiliary pipe 7 and the arc pipe 8 directly exchanges heat with the motor housing 19, thereby increasing the effect of cooling the motor housing 19. A through hole 22 is opened on the motor housing 19, which is connected to the inside of the mounting shell 1 and is located on one side of the rotating blade 15, so that when the rotating blade 15 rotates, the hot air flow in the motor housing 19 is actually extracted and discharged to the outside, thereby increasing the heat dissipation effect of the device.

[0028] like Figure 10-12As shown, part of the structure on the rotor 3 is disclosed. An air duct 301 connected to the mounting shell 1 is provided on the rotor core of the rotor 3, and an air hole 302 is provided on the rotor 3 to connect the air duct 301 with the inside of the motor housing 19. Since the mounting shell 1 does not contain any electronic components, the temperature of the air inside it is lower than the temperature of the air in the motor housing 19. When the rotating blades 15 draw the air in the motor housing 19 outward, the air in the mounting shell 1 can enter the rotor core of the rotor 3 through the air duct 301 and be dispersed into the motor housing 19 through the air hole 302, which further facilitates the heat dissipation in the motor housing 19 and increases the practicality of the device.

[0029] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
