Description

Technical Field

[0001] The invention relates to the technical field of water-cooled motors, in particular to a motor that adopts mixed cooling of air cooling and water cooling. Background Art

[0002] The motor with mixed air-cooling and water-cooling combines the advantages of the two traditional cooling methods and strives to overcome their respective shortcomings. The air-cooling part usually achieves forced air cooling by setting a fan or fan cover on the motor casing, which is suitable for medium power and load applications, while the water-cooling part effectively removes heat from the inside of the motor through the internal water channel and coolant circulation system, which is suitable for high power and heavy load applications.

[0003] In the prior art, the motor can use a combination of air cooling and water cooling to reduce the temperature inside the motor. However, even if a combination of water cooling and air cooling is used, there may still be local hot spots inside the motor, and these local overheating phenomena may affect the overall performance of the motor. In addition, the water-cooling liquid in the water-cooling system needs to be replaced regularly. If the water-cooling liquid is not replaced for a long time, its effect on regulating the temperature inside the motor will be significantly reduced. If the water-cooling liquid of the motor is not replaced for a long time, then the motor mainly relies on the air cooling system to adjust the temperature. The air cooling system uses a fan to discharge the internal hot air to the outside through the vents, thereby reducing the temperature. However, if the temperature inside the motor is high, it is difficult to quickly guide the hot air to the vents by the rotation of the fan alone, which causes the internal temperature of the motor to be unable to reach a suitable level in a short time, thereby affecting the working performance of the motor.

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 14In an embodiment of the present invention, a motor adopting mixed cooling of air cooling and water cooling comprises a housing 1, wherein fixing plates 5 are fixedly arranged axially symmetrically on both sides of the housing 1, a stator core 6 is fixedly arranged between the two fixing plates 5, a plurality of through holes 61 are opened in an annular array on the outer side of the stator core 6, a pipe 2 is fixedly arranged in the through hole 61, the ends of two adjacent pipes 2 are connected end to end through an elbow, one end of a group of adjacent pipes 2 is respectively connected to a water inlet pipe 3 and a water outlet pipe 4, a rotor 7 is arranged in the stator core 6, and the rotor 7 A rotating shaft 9 is fixedly provided through the center, one end of the rotating shaft 9 movably passes through the fixed plate 5 and the housing 1 on one side, the other end of the rotating shaft 9 movably passes through the fixed plate 5 on the other side and a fan 10 is fixedly provided at the end, wherein a plurality of ventilation holes 51 are provided on the fixed plate 5 close to the fan 10, and a heat exhaust component 8 for accelerating the exhaust of hot air is axially symmetrically provided between the two fixed plates 5 and on both sides of the stator core 6; when the motor is in use, three-phase alternating current is applied to the stator core 6 and the stator winding part, and the stator core 6 generates a rotating magnetic field to drive the rotor 7 rotates together with the rotating shaft 9, and the rotation of the rotating shaft 9 can drive the operation of the external device. One end of the water inlet pipe 3 and the water outlet pipe 4 are connected to a pump or other equipment. The pump can pass the water or coolant in the water tank into the pipe 2 through the water inlet pipe 3. The pipe 2 is arranged in a ring array on the outside of the stator core 6. The liquid flowing in the pipe 2 can absorb part of the heat generated by the stator core 6, and then re-enter the water tank or cooling tower through the water outlet pipe 4 for cooling, and then the cooled liquid is re-pumped into the pipe 2 arranged in the through hole 61 through the water inlet pipe 3 for cooling. The absorption of heat and cooling through the circulation of liquid can effectively reduce the temperature inside the motor and avoid the problem of low cooling efficiency of the water cooling system due to the lack of cooling liquid for a long time. In addition, while the water cooling system is running, the rotation of the shaft 9 will also drive the fan 10 to rotate. The rotation of the fan 10 can discharge the hot air generated in the motor to the outside of the motor through the ventilation holes 51 opened in the fixed plate 5. At the same time, the heat exhaust component 8 can continuously "drive" the hot air in the motor to the ventilation holes 51, increase the air flow speed, and promote rapid heat discharge. The shell 1 provides support.

[0032] See also Figure 2-Figure 5As shown, in this embodiment, preferably, the heat removal component 8 includes a transverse plate 81, and the transverse plate 81 is fixedly arranged between the two fixed plates 5. A transverse groove 82 is opened in the center of the transverse plate 81, and a cylinder 83 is slidably arranged in the transverse groove 82. The cylinder 83 is opened at one end close to the stator core 6 with a first arc groove 84, and a rotating cylinder 85 is movably arranged in the cylinder 83. A push plate 86 is fixedly arranged on the outer side of one end of the rotating cylinder 85 close to the stator core 6, and the push plate 86 is rotatably connected to the first arc groove 84; when the motor is working, the cylinder 83 and the rotating cylinder 85 are reciprocated laterally along the transverse groove 82 opened in the transverse plate 81, and the cylinder 83 and the rotating cylinder 85 are moved to When moving in the direction close to the ventilation hole 51, the push plate 86 is in a vertical upward position, so that the heat on the stator core 6 can be quickly transferred to the position close to the ventilation hole 51 and discharged through the ventilation hole 51. The heat conduction efficiency is high, which is conducive to rapid heat dissipation. When the cylinder 83, the rotating cylinder 85 and the push plate 86 are about to reach the end of the side of the horizontal groove 82 close to the ventilation hole 51, the cylinder 83 is moved in the opposite direction, and the rotating cylinder 85 is rotated counterclockwise. The counterclockwise rotation of the rotating cylinder 85 will drive the push plate 86 to rotate counterclockwise along the first arc groove 84, from the original vertical upward to horizontal, which can slow down the air flow speed and avoid transferring too much heat back to the position away from the ventilation hole 51, which is not conducive to heat dissipation.

[0033] See also Figure 4-Figure 6 As shown, in this embodiment, preferably, the end of the cylinder 83 away from the stator core 6 is fixedly connected with a sliding block 11, the sliding block 11 is slidably connected to the transverse groove 82, the rotating cylinder 85 is rotatably connected to the sliding block 11, the sliding block 11 is fixedly connected to a moving block 12 on the side away from the cylinder 83, a limiting groove 121 is provided on the moving block 12, a rotating plate 13 is movably arranged in the limiting groove 121, and the rotating plate 13 is fixedly connected to the end away from the moving block 12 There is a cross bar 14, which is rotatably connected to the inner wall of the shell 1; when the motor is working, the cross bar 14 is rotated, and the rotation of the cross bar 14 drives the rotating plate 13 to rotate. The rotation of the rotating plate 13 causes the other end of the rotating plate 13 to slide along the limiting groove 121, thereby driving the moving block 12 and the sliding block 11 to move back and forth laterally along the cross groove 82. The lateral reciprocating movement of the sliding block 11 will drive the cylinder 83 and the rotating cylinder 85 to move synchronously. During the movement, the heat removal efficiency is accelerated by changing the state of the push plate 86.

[0034] See also Figure 5 and Figure 7-Figure 8As shown, in this embodiment, preferably, a rotating rod 15 is movably provided in the rotating cylinder 85, one end of the rotating rod 15 is rotatably connected to the sliding block 11, the cylinder 83 is provided with a second arc groove 16 on one side of the first arc groove 84, the rotating cylinder 85 is provided with a notch 851 at the position of the second arc groove 16, and a movable plate 17 is provided on the outer side of the rotating rod 15, the direction of the movable plate 17 is opposite to the direction of the push plate 86, and the movable plate 17 is rotatably connected with the notch 851 and the second arc groove 16; when the cylinder 83, the rotating cylinder 85 and the rotating rod 15 move toward the direction close to the ventilation hole 51, the push plate 86 is vertically upward, and the movable plate 17 is vertically downward. The different directions of the push plate 86 and the movable plate 17 can drive the movement of heat in different height intervals inside the motor. Due to the uneven distribution of heat loads in various parts inside the motor and different heat dissipation conditions, There may indeed be differences in the heat in different height intervals within the inner shell of the motor. This difference may cause the temperature in some areas to be too high, affecting the performance and life of the motor. During the movement process, the movement of the push plate 86 and the movable plate 17 can drive more heat to move to the ventilation hole 51, thereby accelerating the discharge of heat. When the cylinder 83, the rotating cylinder 85 and the rotating rod 15 move in a direction away from the ventilation hole 51, the rotating cylinder 85 is rotated counterclockwise to make the push plate 86 horizontal. At the same time, the moving rod 22 is rotated clockwise to make the movable plate 17 rotate along the second arc groove 16 and the notch 851, so that the movable plate 17 is also in a horizontal state, so that excessive heat can be avoided from being brought to a position away from the ventilation hole 51 when returning. In addition, when the push plate 86 and the movable plate 17 are in a horizontal state, they are both facing the side away from the ventilation hole 51, so that the push plate 86 and the movable plate 17 can move a longer distance while maintaining a vertical state.

[0035] See also Figure 9-10As shown, in this embodiment, preferably, a sleeve 18 is fixedly provided at one end of the rotating cylinder 85 away from the sliding block 11, and the sleeve 18 is rotatably connected to the inner wall of the cylinder 83.

A notch 191 is provided at the bottom of the positioning plate 19, and a limiting rod 21 is slidably provided in the notch 191. The limiting rod 21 is fixedly connected to the bottom of the movable block 20, and the rotating rod 15 An arc groove 151 is opened at the end, and the limit rod 21 slides and fits with the arc groove 151; when the cylinder 83, the rotating cylinder 85 and the rotating rod 15 move in the direction away from the ventilation hole 51, the rotating cylinder 85 is rotated counterclockwise to make the push plate 86 turn to a horizontal state. At the same time, the movable block 20 is moved laterally along the positioning plate 19. The movement of the movable block 20 drives the limit rod 21 to move along the slot 191. The movement of the limit rod 21 along the arc groove 151 will drive the rotating rod 15 to rotate clockwise, so that the movable plate 17 also becomes a horizontal state.

[0036] See also Fig. 9 As shown, in the present embodiment, preferably, a curved groove 181 is provided in the sleeve 18, and a moving rod 22 is slidably provided in the curved groove 181, and one end of the moving rod 22 is fixedly connected to the top of the movable block 20; when the cylinder 83, the rotating cylinder 85 and the rotating rod 15 move in the direction away from the ventilation hole 51, the rotating cylinder 85 is rotated counterclockwise to make the push plate 86 turn to a horizontal state, and the counterclockwise rotation of the sleeve 18 of the rotating cylinder 85 rotates the curved groove 181, and the rotation of the curved groove 181 will drive the moving rod 22 and the movable block 20 to move laterally, and the movement of the movable block 20 will drive the rotating rod 15 to rotate through the limit rod 21, and the rotation of the rotating rod 15 drives the movable plate 17 to become a horizontal state. In this step, the push plate 86 and the movable plate 17 are rotated at the same time through the cooperation of the curved groove 181, the moving rod 22, the movable block 20, the limit rod 21 and the arc groove 151, and the operation is convenient and quick.

[0037] See also Figure 11-Figure 12As shown, in the present embodiment, preferably, a groove 831 is provided on the outer side of the cylinder 83 located in the transverse groove 82, a positioning rod 23 is fixedly provided on the outer side of the rotating cylinder 85, a vertical plate 24 is fixedly provided on the side of the transverse plate 81 close to the ventilation hole 51, a lifting plate 25 is slidably provided in the vertical plate 24, a positioning block 26 is fixedly provided on one side of the lifting plate 25, a part of the bottom area of ​​the positioning block 26 is designed to be inclined, and the positioning rod 23 is movably abutted against the positioning block 26; when the push plate 86 is kept vertically upward and the movable plate 17 is kept vertically downward and moves in the direction close to the ventilation hole 51, when it is about to reach the end of the transverse groove 82, the positioning rod 23 will first abut against the positioning block 26, and the positioning block 26 will be moved to the left and right sides of the rotating cylinder 85. The bottom is designed to be inclined, so that when the positioning rod 23 abuts against the positioning block 26, the positioning rod 23 can tilt upward at an angle, and then the cylinder 83 continues to move with the movement of the sliding block 11, and the positioning rod 23 will gradually rotate counterclockwise to drive the lifting plate 25 to move upward along the vertical plate 24. The counterclockwise rotation of the positioning rod 23 will drive the rotating cylinder 85 to rotate counterclockwise. The height of the bottom of the vertical plate 24 is higher than the top height of the rotating cylinder 85. In this way, when the positioning rod 23 rotates 90 degrees counterclockwise along the groove 831, the vertical plate 24 will not collide with the rotating cylinder 85. In this step, the positioning rod 23 cooperates with the positioning block 26 to realize the counterclockwise rotation of the rotating cylinder 85 during the movement, and finally the push plate 86 and the moving plate 17 are transformed into a horizontal state.

[0038] See also Figure 7 and Fig.13 As shown, in the present embodiment, preferably, a rotating ring 27 is fixedly sleeved on one side of the rotating cylinder 85 close to the positioning rod 23, a limiting ball 28 is fixedly arranged on the outer side of the rotating ring 27, the limiting ball 28 is made of elastic material, a limiting hole 832 is provided at the bottom of the cylinder 83, and the limiting ball 28 is movably engaged with the limiting hole 832; after the positioning rod 23 and the positioning block 26 are abutted, the rotating cylinder 85 rotates 90 degrees counterclockwise, which will drive the rotating ring 27 to rotate 90 degrees counterclockwise. The rotation of the rotating ring 27 will drive the limiting ball 28 to rotate. The limiting ball 28 is made of a material with a spring 31. During the rotation process, it is squeezed by the inner wall of the cylinder 83 and is in a compressed state. When the rotating ring 27 drives the limiting ball 28 to rotate to the position of the limiting hole 832, the limiting ball 28 will engage with the limiting hole 832. At this time, the rotating cylinder 85 just rotates 90 degrees counterclockwise, and the push plate 86 and the movable plate 17 both become horizontal. At this time, the sliding block 11 will drive the cylinder 83, the rotating cylinder 85 and the rotating rod 15 to move in a direction away from the ventilation hole 51. At this time, the push plate 86 and the movable plate 17 will always remain in a horizontal state.

[0039] See also Fig.11 and Figure 13-14As shown, in this embodiment, preferably, a ring 29 is fixedly provided in the limiting hole 832, a push rod 30 is movably provided at the center of the ring 29, one end of the push rod 30 is movably abutted against the limiting ball 28, a spring 31 is fixedly provided between the positioning rod 23 and the ring 29, a fixing block 32 is fixedly provided in the horizontal plate 81, an inclined groove 321 is provided on the fixing block 32, and the push rod 30 is movably abutted against the inclined groove 321; the cylinder 83, the rotating cylinder 85 and the rotating rod 1 The movement in the direction away from the ventilation hole 51 will also drive the push rod 30 to move. In the initial state, a part of the push rod 30 is located outside the limiting hole 832 under the action of the spring 31. As the cylinder 83 moves, the push rod 30 moves from the lower part to the higher part along the inclined groove 321 provided in the fixing block 32. During the movement, the push rod 30 moves toward the inside of the limiting hole 832 to push the limiting ball 28 to release the engagement with the limiting hole 832. In this process, the spring 31 is compressed, and the ring 29 provides support for the spring 31.

[0040] See also Figure 5 and Fig.11 As shown, in the present embodiment, preferably, a fixing ring 33 is fixedly provided on the outer side of the rotating cylinder 85 close to the sliding block 11, a first torsion spring 34 is fixedly provided between the fixing ring 33 and the sliding block 11, and a second torsion spring 35 is fixedly provided between the sleeve 18 and the cylinder 83; under the cooperation of the positioning rod 23 and the positioning block 26, the rotating cylinder 85 will rotate 90 degrees counterclockwise, during which the fixing ring 33 and the sleeve 18 will be driven to rotate, thereby driving the first torsion spring 34 and the second torsion spring 35 to twist, and then the limiting ball 28 and the limiting hole 832 are engaged, and the first torsion spring 34 and the second torsion spring 35 always maintain a twisted state on the way back until the limiting ball 28 and the limiting hole 832 are released from the engagement of the inclined groove 321 and the push rod 30, at which time the first torsion spring 34 and the second torsion spring 35 will drive the push plate 86 and the movable plate 17 to return to a vertical state during the recovery process, so that the heat can be easily pushed to the position of the ventilation hole 51.

[0041] The working principle of the present invention is: when the motor is working, the cross bar 14 is rotated, and the rotation of the cross bar 14 drives the rotating plate 13 to rotate. The rotation of the rotating plate 13 causes the other end of the rotating plate 13 to slide along the limiting groove 121, thereby driving the moving block 12 and the sliding block 11 to move back and forth laterally along the cross groove 82. The lateral reciprocating movement of the sliding block 11 drives the cylinder 83 and the rotating cylinder 85 to move synchronously. When the cylinder 83, the rotating cylinder 85 and the rotating rod 15 move toward the direction close to the ventilation hole 51, the push plate 86 is vertically upward and the moving plate 17 is vertically downward. The different directions of the push plate 86 and the moving plate 17 can drive the movement of heat in different height intervals inside the motor. Due to the uneven distribution of heat loads in various parts inside the motor and different heat dissipation conditions, There may indeed be differences in the heat in different height intervals in the inner shell of the motor. This difference may cause the temperature in some areas to be too high, affecting the performance and life of the motor. During the movement, the movement of the push plate 86 and the moving plate 17 can drive more heat to move to the ventilation hole 51, thereby accelerating the discharge of heat. When it is about to reach the end of the horizontal groove 82, the positioning rod 23 will first abut against the positioning block 26. The bottom of the positioning block 26 is designed to be inclined, so that the positioning rod 23 can be tilted upward at an angle when the positioning rod 23 abuts against the positioning block 26, and then the cylinder 83 continues to move with the movement of the sliding block 11. The positioning rod 23 will gradually rotate counterclockwise, thereby driving the lifting plate 25 to move upward along the vertical plate 24. The counterclockwise rotation of the positioning rod 23 will drive the rotating cylinder 85 to rotate counterclockwise. The needle rotates, and the counterclockwise rotation of the rotating cylinder 85 will drive the push plate 86 to rotate counterclockwise along the first arc groove 84, from the original vertical upward to horizontal, which can slow down the air flow speed and avoid transferring too much heat to a position far away from the ventilation hole 51, which is not conducive to heat dissipation. The counterclockwise rotation sleeve 18 of the rotating cylinder 85 rotates the curved groove 181, and the rotation of the curved groove 181 will drive the moving rod 22 and the movable block 20 to move horizontally. The movement of the movable block 20 will drive the rotating rod 15 to rotate through the limit rod 21. The rotation of the rotating rod 15 drives the moving plate 17 to rotate clockwise and become horizontal. At the same time, after the positioning rod 23 and the positioning block 26 abut, the rotating cylinder 85 rotates 90 degrees counterclockwise, which will drive the rotating ring 27 to rotate counterclockwise by 9 0 degrees, the rotation of the rotating ring 27 will drive the limiting ball 28 to rotate. The limiting ball 28 is made of a material with a spring 31. During the rotation process, it is squeezed by the inner wall of the cylinder 83 and is in a compressed state. When the rotating ring 27 drives the limiting ball 28 to rotate to the position of the limiting hole 832, the limiting ball 28 will engage with the limiting hole 832. At this time, the rotating cylinder 85 just rotates 90 degrees counterclockwise, and the push plate 86 and the moving plate 17 become horizontal. At this time, the sliding block 11 will drive the cylinder 83, the rotating cylinder 85 and the rotating rod 15 to move in a direction away from the ventilation hole 51. At this time, the push plate 86 and the moving plate 17 will always remain in a horizontal state. The push rod 30 will move from the lower part to the higher part along the inclined groove 321 opened in the fixed block 32 during the movement of the cylinder 83.During the movement, the push rod 30 will move toward the inside of the limiting hole 832 to push the limiting ball 28 to release the engagement with the limiting hole 832. Then, during the recovery process of the first torsion spring 34 and the second torsion spring 35, the push plate 86 and the moving plate 17 will be driven to return to the vertical state, so that the heat can be easily pushed to the position of the ventilation hole 51.
