Description

Technical Field

[0001] The present invention relates to the technical field of motor heat dissipation, and particularly to a high-efficiency heat dissipation asynchronous motor. Background Art

[0002] An asynchronous motor is an AC motor that works based on the principle of electromagnetic induction. Its rotor speed is always lower than the synchronous speed of the stator rotating magnetic field, so it is called "asynchronous". Its core structure includes a stator winding and a squirrel-cage / wound rotor. When the stator is energized, a rotating magnetic field is generated, inducing a current in the rotor conductors and generating a torque to drive the rotation. Due to its simple structure, low cost, and high reliability, asynchronous motors are widely used in industrial equipment, household appliances, and the new energy field.

[0003] The main reason for dissipating heat from an asynchronous motor is that heat is generated during its operation. If the heat cannot be dissipated in time, it may lead to a decline in motor performance, a shortening of its lifespan, or even damage. Motor windings usually use materials such as insulating paint and epoxy resin. Excessive temperature will accelerate the carbonization and embrittlement of the insulating material, ultimately resulting in insulation failure, leading to short circuits or breakdowns. Extreme high temperatures may ignite surrounding combustibles or cause misoperation of protection devices (such as thermal relays) to stop the machine. Heat dissipation is the core guarantee for the reliable operation of asynchronous motors, directly related to efficiency, lifespan, and safety. During design and use, factors such as power, load, and environment need to be considered to select a reasonable cooling method and regularly maintain the heat dissipation system (such as cleaning the fan and ventilation duct) to ensure that the motor operates within a safe temperature range.

[0004] Efficient heat dissipation design can significantly reduce the operating temperature of the motor, reducing problems such as insulation aging, efficiency decline, and lifespan shortening caused by overheating. By optimizing heat dissipation (such as enhancing air cooling / liquid cooling, heat pipe heat conduction, etc.), the winding resistance can be maintained stable, copper loss and iron loss can be reduced, and energy efficiency can be improved (the efficiency can be increased by 1 - 3%). At the same time, it supports a higher power density and continuous overload capacity, and is suitable for scenarios with strict heat dissipation requirements such as electric vehicles and industrial frequency converters.

[0005] Chinese Patent No. CN116827017B discloses a guide vane for enhanced heat dissipation of a rotor axially air-cooled induction motor and its optimization method. This device dissipates heat from the motor by setting multiple groups of guide vanes and controlling their rotation, using a centrifugal fan. However, this technical solution is prone to increasing the burden on the motor in actual use, resulting in problems such as abnormal noise and noise, thereby increasing the failure rate. In addition, in a harsh environment, the heat dissipation effect of this solution is also relatively limited. Summary of the Invention

Detailed implementation manners

[0031] Referring to Figures 1 to 13 a highly efficient heat dissipation asynchronous motor shown in the figure, which includes a heat dissipation component 1 for dissipating heat from the asynchronous motor 101. The heat dissipation component 1 changes the air volume of the outer shell of the asynchronous motor 101 by adjusting the opening and closing angles of multiple groups of guide vanes 104, improving the heat dissipation efficiency of the asynchronous motor 101. And the heat dissipation component 1 controls the guide vanes 104 through the centrifugal force generated by the asynchronous motor 101, and adjusts the working angle of the guide vanes 104 in real time according to the rotation speed of the asynchronous motor 101, avoiding energy waste while increasing the heat dissipation efficiency. An emergency component 2 is arranged on the heat dissipation component 1, and the emergency component 2 controls the guide vanes 104. When the asynchronous motor 101 is at a high temperature but the centrifugal force is insufficient, the emergency component 2 is triggered, and the emergency component 2 drives the guide vanes 104 to open and close to dissipate heat from the asynchronous motor 101. An intake component 3 for filtering air is arranged on the side of the heat dissipation component 1. The intake component 3 filters the air entering the asynchronous motor 101 and cleans the filtered debris. The present invention improves the heat dissipation efficiency of the asynchronous motor 101 by setting a horn-shaped acceleration air duct, and can still dissipate heat from the asynchronous motor 101 when the asynchronous motor 101 fails.

[0032] The heat dissipation component 1 includes an asynchronous motor 101. At one end of the asynchronous motor 101 away from its output shaft, there is a flow guide cover 102 and a heat dissipation shaft 107. The heat dissipation shaft 107 is rotationally connected to the asynchronous motor 101. A plurality of groups of fan blades 108 are arranged on the heat dissipation shaft 107. When the heat dissipation shaft 107 rotates, it drives the fan blades 108 to rotate, and the fan blades 108 dissipate heat inside the asynchronous motor 101. A plurality of groups of trigger blocks 109 are also slidably arranged on the heat dissipation shaft 107. A first spring 110 is arranged between the trigger block 109 and the heat dissipation shaft 107. When the heat dissipation shaft 107 rotates, the trigger block 109 rotates on the heat dissipation shaft 107 due to centrifugal force. The higher the rotation speed of the heat dissipation shaft 107, the greater the centrifugal force received by the trigger block 109, and the greater the distance of the trigger block 109 from the axis of the heat dissipation shaft 107. When the rotation speed of the heat dissipation shaft 107 decreases, the trigger block 109 is reset by the deformation restoring force of the first spring 110. The rotation speed of the heat dissipation shaft 107 changes the sliding distance of the trigger block 109. A second chamber 118, an air outlet 116 and a first chamber 117 are arranged in the flow guide cover 102. A baffle 103 is slidably arranged on the flow guide cover 102, and the baffle 103 closes the air outlet 116. When the fan blades 108 rotate, the wind fanned by them passes through the second chamber 118 and is discharged through the air outlet 116. When the baffle 103 blocks the air outlet 116, the wind fanned by the fan blades 108 enters the first chamber 117 through the second chamber 118 and is then discharged through the first chamber 117. A plurality of groups of flow guide plates 104 are rotatably arranged on the flow guide cover 102. A connecting buckle 106 is arranged on the flow guide plate 104. Changing the angle of the flow guide plate 104 on the flow guide cover 102 realizes different air intake amounts in the first chamber 117. A plurality of groups of support columns 111 are slidably arranged on the flow guide cover 102. The support columns 111 are in contact with the bottom of the flow guide plate 104. When the support columns 111 slide on the flow guide cover 102, they drive the flow guide plate 104 to rotate on the flow guide cover 102. A plurality of groups of first limiting holes 112 are arranged on the support columns 111. A first limiting column 113 and a reset rod 115 are slidably arranged on the flow guide cover 102. A second spring 114 is arranged between the first limiting column 113 and the flow guide cover 102. A reset block 119 is arranged on the reset rod 115, and the reset block 119 is in contact with the first limiting column 113. The first limiting column 113 is inserted into the first limiting hole 112 to limit the support column 111. When the heat dissipation shaft 107 rotates, the trigger block 109 slides on the heat dissipation shaft 107 due to centrifugal force. The trigger block 109 contacts the support column 111 and pushes the support column 111 to slide on the flow guide cover 102. The support column 111 pushes the flow guide plate 104 to rotate on the flow guide cover 102, changing the angle between the flow guide plate 104 and the flow guide cover 102. When the support column 111 is pushed by the trigger block 109, it drives the first limiting hole 112 to move. The first limiting column 113 is inserted into the first limiting hole 112. According to the change in the rotation speed of the heat dissipation shaft 107, the sliding distance of the trigger block 109 changes. At this time, the distance that the trigger block 109 pushes the support column 111 to slide on the flow guide cover 102 is different, and the angle at which the support column 111 pushes the flow guide plate 104 to rotate changes synchronously.Change the air volume passing through the housing of the asynchronous motor 101. The limit post 113 is inserted into the first limit hole 112 to fix the support column 111. When the support column 111 moves upward, the support column 111 drives the first limit hole 112 to press the first limit post 113, so that the first limit post 113 is inserted into different first limit holes 112. At the same time, when the rotational speed changes slightly, it is avoided that the support column 111 resets by gravity, resulting in the reset of the guide vane 104 and affecting the heat dissipation efficiency. When the rotational speed of the heat dissipation shaft 107 becomes smaller and the trigger block 109 is not in contact with the support column 111, the drive reset rod 115 slides on the guide vane cover 102. The reset rod 115 drives the reset block 119 to move, and the reset block 119 drives the first limit post 113 to compress the second spring 114. At this time, the first limit post 113 releases the limit on the first limit hole 112, and the support column 111 resets. The support column 111 drives the guide vane 104 to reset, avoiding energy waste and noise pollution caused by the long-term expansion of the guide vane 104. Multiple groups of limit rods 105 are provided on the guide vane cover 102.,

[0033] The emergency component 2 includes a mounting frame 201 slidably mounted on the fairing 102. At the upper end of the mounting frame 201, multiple sets of first gears 202 are rotatably arranged. A torsion spring is arranged at the rotating position of the first gear 202 and the mounting frame 201. A third limiting post 207 is slidably arranged on the mounting frame 201. The third limiting post 207 is inserted into the rotating shaft of the first gear 202 to lock the first gear 202. An inclined block 208 is arranged at the lower end of the third limiting post 207. When the mounting frame 201 approaches the fairing 102, the limiting rod 105 is inserted into the inclined block 208. The limiting rod 105 pushes the inclined block 208 to slide on the mounting frame 201. The inclined block 208 drives the third limiting post 207 to move. The third limiting post 207 is pulled out from the first gear 202 to release the lock on the first gear 202. At this time, the first gear 202 rotates through the deformation restoring force of the torsion spring. Multiple sets of deformation rods 204 are arranged at the lower end of the mounting frame 201. The part of the deformation rod 204 in contact with the asynchronous motor 101 is made of shape memory alloy. When the surface of the asynchronous motor 101 overheats, the deformation rod 204 deforms and drives the mounting frame 201 to approach the fairing 102, realizing the drive of the mounting frame 201. A second limiting post 206 is arranged on the deformation rod 204. The second limiting post 206 is inserted into the refrigerating plate 205. The refrigerating plate 205 is slidably mounted on the asynchronous motor 101. A third spring 209 is arranged between the refrigerating plate 205 and the asynchronous motor 101. The refrigerating plate 205 cools the surface of the asynchronous motor 101. When the deformation rod 204 moves, it drives the second limiting post 206 to move. The second limiting post 206 is pulled out from the refrigerating plate 205. The refrigerating plate 205 is reset through the deformation restoring force of the third spring 209. The emergency component 2 also includes multiple sets of second gears 203 rotatably mounted on the fairing 102. The second gear 203 is connected to the connecting buckle 106 through a thin rope. One end of the thin rope is wound around the second gear 203, and the other end of the thin rope is connected to the connecting buckle 106. When the mounting frame 201 approaches the fairing 102, the first gear 202 meshes with the second gear 203. When the third limiting post 207 is pulled out from the first gear 202, the first gear 202 drives the second gear 203 to rotate. The second gear 203 drives the thin rope to wind around the second gear 203. The thin rope pulls the deflector 104 to rotate on the fairing 102, pulling the deflector 104 to the maximum working angle.

[0034] The air intake assembly 3 includes a filter plate 301 installed on the fairing 102. When dissipating heat from the asynchronous motor 101, air enters the asynchronous motor 101 after passing through the filter plate 301. The filter plate 301 filters the air. A first adjustment block 302 is slidably arranged on the filter plate 301. A scraper 303 is arranged on the first adjustment block 302. Both sides of the scraper 303 are beveled surfaces. The scraper 303 scrapes the debris on the surface of the filter plate 301, reducing the probability of blockage of the filter plate 301. A second adjustment block 305 is slidably arranged on the scraper 303. A swing rod 306 is rotatably arranged on the second adjustment block 305. A dredging head 307 is arranged on the swing rod 306. The dredging head 307 is connected to the swing rod 306 through a spline shaft. When the filter holes on the filter plate 301 are blocked, the second adjustment block 305 is driven to slide on the scraper 303. The second adjustment block 305 drives the swing rod 306 to move. The swing rod 306 is driven to rotate on the second adjustment block 305. The swing rod 306 drives the dredging head 307 to align with the blocked holes. After alignment, the dredging head 307 is driven to slide on the swing rod 306. The dredging head 307 is inserted into the blocked holes of the filter plate 301. The dredging head 307 is driven to rotate, and the dredging head 307 dredges the blocked holes. Knocking discs 304 are slidably arranged on both sides of the scraper 303. A fourth spring 309 is arranged between the knocking discs 304 and the scraper 303. Cam 308 is also arranged on both sides of the scraper 303. The cam 308 is in contact with the knocking disc 304. By driving the cam 308 to rotate, the cam 308 drives the knocking disc 304 to reciprocate slidably on the scraper 303. The knocking disc 304 knocks on the filter plate 301, knocking off the floating dust on the surface of the filter plate 301.

[0035] Working principle: When the asynchronous motor 101 works, the heat dissipation shaft 107 rotates synchronously. When the heat dissipation shaft 107 rotates, it drives the fan blade 108 to rotate. When the fan blade 108 rotates, it dissipates heat inside the asynchronous motor 101. In a low-temperature state, the air fanned by the fan blade 108 is discharged through the air outlet 116. The minimum working angle is formed between the deflector 104 and the fairing 102. At this time, the naturally flowing air completes the heat dissipation of the asynchronous motor 101.

[0036] When the rotational speed of the asynchronous motor 101 increases, the heat generated by the asynchronous motor 101 becomes larger, and rapid heat dissipation is required. The drive baffle 103 moves to close the air outlet 116. At this time, the airflow fanned out by the fan blade 108 is discharged through the chamber two 118 and the chamber one 117 to dissipate heat from the asynchronous motor 101. At the same time, the rotational speed of the heat dissipation shaft 107 is increased. When the rotational speed of the heat dissipation shaft 107 becomes faster, the centrifugal force received by the trigger block 109 becomes larger, and the distance between the trigger block 109 and the axis of the heat dissipation shaft 107 becomes larger. The trigger block 109 pushes the support column 111 to slide on the flow guide cover 102. The support column 111 pushes the flow guide plate 104 to rotate on the flow guide cover 102. The support column 111 drives the first limiting hole 112 to move. The support column 111 pushes the first limiting post 113, and the first limiting post 113 is inserted into different first limiting holes 112 to fix the support column 111 and ensure the stability of the unfolded flow guide plate 104. The flow guide plate 104 forms a horn-shaped accelerating air duct, increasing the air volume passing through the surface of the housing of the asynchronous motor 101 and improving the heat dissipation efficiency of the housing of the asynchronous motor 101. When the asynchronous motor 101 completes heat dissipation, the rotational speed of the heat dissipation shaft 107 decreases. At this time, the trigger block 109 is reset by the deformation restoring force of the first spring 110. When the trigger block 109 and the support column 111 are not in contact for a long time, the drive reset rod 115 slides on the flow guide cover 102. The reset rod 115 drives the reset block 119 to move. The reset block 119 pulls the first limiting post 113 to move. The reset block 119 pulls out the first limiting post 113 from the first limiting hole 112. At this time, the first limiting post 113 releases the fixation of the support column 111. The support column 111 is reset by gravity. At the same time, the flow guide plate 104 is reset to the minimum working angle by gravity to avoid energy waste.

[0037] When the temperature of the outer shell of the asynchronous motor 101 is too high, but due to other reasons such as faults, the rotation speed of the heat dissipation shaft 107 does not increase, and the driving of the deflector 104 cannot be achieved, the outer shell of the asynchronous motor 101 heats the bottom of the deformation rod 204. At this time, the part of the bottom of the deformation rod 204 made of shape memory alloy is heated and restored to its shape. The deformation rod 204 drives the mounting bracket 201 to approach the guide cover 102. At the same time, the deformation rod 204 drives the second limiting post 206 to be pulled out of the refrigeration plate 205. The second limiting post 206 releases the limit on the refrigeration plate 205. At this time, the refrigeration plate 205 is reset by the deformation restoring force of the third spring 209. The refrigeration plate 205 quickly fits with the asynchronous motor 101. The refrigeration plate 205 cools the asynchronous motor 101. The mounting bracket 201 drives the first gear 202 to approach the guide cover 102, and the first gear 202 meshes with the second gear 203. At the same time, the limiting rod 105 pushes the inclined block 208 to slide on the mounting bracket 201. The inclined block 208 drives the third limiting post 207 to move. The third limiting post 207 releases the lock on the first gear 202. The first gear 202 rotates back by the torsion spring. The first gear 202 drives the second gear 203 to rotate. The second gear 203 winds the thin rope around the second gear 203. The second gear 203 drives the deflector 104 to rotate, adjusts the deflector 104 to the maximum working angle, forms a trumpet-shaped acceleration air duct to dissipate heat from the outer shell of the asynchronous motor 101, and at the same time gives an alarm to remind the staff to repair the asynchronous motor 101 and restore the rotation speed of the heat dissipation shaft 107.

[0038] The gas for dissipating heat from the asynchronous motor 101 enters the asynchronous motor 101 through the filter plate 301. When the gas passes through the filter plate 301, the filter plate 301 filters the air. When there are sundries on the surface of the filter plate 301, the driving adjustment block one 302 slides on the filter plate 301. The adjustment block one 302 drives the scraper 303 to move. The scraper 303 scrapes off the sundries on the surface of the filter plate 301. When the filter holes on the filter plate 301 are blocked, the driving adjustment block two 305 slides on the scraper 303. The adjustment block two 305 drives the swing rod 306 to move. The driving swing rod 306 rotates on the adjustment block two 305. The swing rod 306 drives the dredging head 307 to align with the blocked hole. After alignment, the driving dredging head 307 slides on the swing rod 306. The dredging head 307 is inserted into the blocked hole of the filter plate 301. The driving dredging head 307 rotates. The dredging head 307 dredges the blocked hole. Knocking disks 304 are slidably arranged on both sides of the scraper 303. A fourth spring 309 is arranged between the knocking disk 304 and the scraper 303. Cam 308 is also arranged on both sides of the scraper 303. The cam 308 is in contact with the knocking disk 304. The driving cam 308 rotates. The cam 308 drives the knocking disk 304 to slide back and forth on the scraper 303. The knocking disk 304 knocks on the filter plate 301 to knock off the floating dust on the surface of the filter plate 301.

[0039] The heat dissipation component 1 provided by the present invention dissipates heat from the asynchronous motor 101 by changing the air volume flowing through, and controls the rotation angle of the guide vane 104 in real time according to the working state of the asynchronous motor 101. The rotation of the guide vane 104 is controlled by the centrifugal force generated by the asynchronous motor 101, so that multiple groups form a trumpet-shaped accelerating air duct to improve the heat dissipation efficiency of the outer shell of the asynchronous motor 101. The emergency component 2 provided on the heat dissipation component 1 performs emergency control on the guide vane 104. When the heat dissipation component 1 cannot provide enough centrifugal force to drive the guide vane 104, the emergency component 2 controls the rotation angle of the guide vane 104 through a shape memory alloy, avoiding damage caused by overheating of the asynchronous motor 101. The air intake component 3 provided by the present invention automatically filters the intake air, preventing debris and dust from entering the asynchronous motor 101 and causing damage to the asynchronous motor 101. The air intake component 3 can clean the filter holes, avoiding a decrease in the intake air volume caused by blocked filter holes.
