Description

Technical Field

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

[0002] An asynchronous motor is an AC electric motor that operates based on the principle of electromagnetic induction. Its rotor speed is always lower than the synchronous speed of the stator's rotating magnetic field, hence the name "asynchronous." Its core structure consists of stator windings and a squirrel-cage / wound rotor. When the stator is energized, it generates a rotating magnetic field, inducing current in the rotor conductors and generating torque to drive rotation. Due to their simple structure, low cost, and high reliability, asynchronous motors are widely used in industrial equipment, household appliances, and the new energy sector.

[0003] The main reason for cooling asynchronous motors is that they generate heat during operation. If the heat cannot be dissipated in time, it may lead to degraded motor performance, shortened lifespan, or even damage. Motor windings usually use insulating varnish, epoxy resin and other materials. Excessive temperature will accelerate the carbonization and embrittlement of the insulating material, eventually leading to insulation failure, causing short circuit or breakdown. Extreme high temperature may ignite surrounding combustibles or cause protective devices (such as thermal relays) to malfunction and shut down. Heat dissipation is the core guarantee for the reliable operation of asynchronous motors and is directly related to efficiency, lifespan and safety. In design and use, it is necessary to combine power, load, environment and other factors to select a reasonable cooling method and regularly maintain the heat dissipation system (such as cleaning fans and ventilation ducts) to ensure that the motor operates within a safe temperature range.

[0004] Efficient heat dissipation significantly reduces motor operating temperatures, minimizing insulation aging, efficiency degradation, and lifespan reduction caused by overheating. Optimized heat dissipation (such as enhanced air / liquid cooling and heat pipe conduction) maintains stable winding resistance, reduces copper and iron losses, and improves energy efficiency (by 1-3%). It also supports higher power density and sustained overload capability, making it suitable for demanding heat dissipation scenarios such as electric vehicles and industrial inverters.

[0005] Chinese invention patent publication number CN116827017B discloses a heat-enhancing guide vane for an axially air-cooled induction motor and its optimization method. This device utilizes a centrifugal fan to dissipate heat from the motor by installing multiple sets of guide vanes and controlling their rotation. However, this technical solution can increase the burden on the motor in practice, leading to problems such as abnormal sounds and noise, and thus increasing the failure rate.

DETAILED DESCRIPTION

[0031] refer to Figures 1 to 13 The high-efficiency heat dissipation asynchronous motor shown in the figure 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 asynchronous motor 101 housing by adjusting the opening and closing angles of multiple groups of guide plates 104, thereby improving the heat dissipation efficiency of the asynchronous motor 101. The heat dissipation component 1 controls the guide plates 104 through the centrifugal force generated by the asynchronous motor 101, and adjusts the working angle of the guide plates 104 in real time according to the speed of the asynchronous motor 101, thereby avoiding energy waste and increasing heat dissipation efficiency. An emergency component 2 is provided on the heat dissipation component 1, and the emergency component 2 is used for The guide plate 104 is controlled. When the asynchronous motor 101 is at a high temperature but the centrifugal force is insufficient, the emergency component 2 is triggered. The emergency component 2 drives the guide plate 104 to open and close to dissipate heat to the asynchronous motor 101. An air intake component 3 for filtering air is provided on the side of the heat dissipation component 1. The air 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 providing a trumpet-shaped acceleration air duct, and can still dissipate heat to the asynchronous motor 101 when a fault occurs in the asynchronous motor 101.

[0032] The heat dissipation assembly 1 includes an asynchronous motor 101. An end of the asynchronous motor 101 away from its output shaft is provided with a deflector 102 and a heat dissipation shaft 107. The heat dissipation shaft 107 is rotatably connected to the asynchronous motor 101. A plurality of fan blades 108 are provided on the heat dissipation shaft 107. When the heat dissipation shaft 107 rotates, the fan blades 108 are driven to rotate. The fan blades 108 dissipate heat inside the asynchronous motor 101. A plurality of trigger blocks 109 are also slidably provided on the heat dissipation shaft 107. A spring 110 is provided 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 speed of the heat dissipation shaft 107, the greater the centrifugal force applied to the trigger block 109, and the greater the distance between the trigger block 109 and the axis center of the heat dissipation shaft 107. When the speed of the heat dissipation shaft 107 decreases, the trigger block 109 is reset by the deformation restoring force of the spring 110. The speed of the heat dissipation shaft 107 changes the sliding distance of the trigger block 109. The air deflector 102 is provided with a chamber 2 118, an air outlet 116 and a chamber 1 117. The air deflector 102 is provided with a baffle 103 for sliding. The baffle 103 closes the air outlet 116. When the fan blade 108 rotates, the wind fanned by the fan blade 108 passes through the chamber 2 118 and is discharged through the air outlet 116. When the baffle 103 blocks the air outlet 116, the wind fanned by the fan blade 108 passes through the chamber 2 118 into the chamber 1 117 and then is discharged through the chamber 1 117. A plurality of groups of guide plates 104 are rotatably provided on the air deflector 102, and a connecting buckle 1 is provided on the guide plate 104. 06. Changing the angle of the guide plate 104 on the guide cover 102 realizes different air intake volumes in the chamber 117. The guide cover 102 is provided with multiple sets of support columns 111 for sliding. The support columns 111 fit the bottom of the guide plate 104. When the support columns 111 slide on the guide cover 102, the guide plate 104 is driven to rotate on the guide cover 102. Multiple sets of limiting holes 112 are provided on the support columns 111. A limiting column 113 and a reset rod 115 are provided for sliding on the guide cover 102. A spring 2 114 is provided between the limiting column 113 and the guide cover 102. A reset block 119 is provided on the reset rod 115. The reset block 119 fits the limiting column 113. The limiting column 113 is inserted into the 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 air deflector 102. The support column 111 pushes the guide plate 104 to rotate on the air deflector 102, changing the angle between the guide plate 104 and the air deflector 102. When the support column 111 is pushed by the trigger block 109, it drives the limit hole 112 to move, and the limit column 113 is inserted into the limit hole 112. According to the change in the 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 air deflector 102 is different, and the angle of rotation of the guide plate 104 driven by the support column 111 changes synchronously.To change the air volume passing through the housing of the asynchronous motor 101, the limiting column 113 is inserted into the limiting hole 112 to fix the support column 111. When the support column 111 moves upward, the support column 111 drives the limiting hole 112 to press the limiting column 113, so that the limiting column 113 is inserted into different limiting holes 112. At the same time, it is prevented that the support column 111 is reset by gravity when the speed changes slightly, causing the guide plate 104 to reset and affect the heat dissipation efficiency. When the speed of the heat dissipation shaft 107 decreases, the trigger block 10 When the support column 111 is no longer in contact with the support column 111, the reset rod 115 is driven to slide on the air deflector 102. The reset rod 115 drives the reset block 119 to move. The reset block 119 drives the limit column 113 to compress the spring 2 114. At this time, the limit column 113 releases the limit on the limit hole 112, and the support column 111 is reset. The support column 111 drives the deflector 104 to reset, avoiding the energy waste and noise pollution caused by the long-term deployment of the deflector 104. The air deflector 102 is provided with multiple sets of limit rods 105.

[0033] The emergency component 2 includes a mounting frame 201 slidably mounted on the air deflector 102, and a plurality of gears 202 are rotatably provided on the upper end of the mounting frame 201. A torsion spring is provided at the rotation position of the gear 202 and the mounting frame 201. A limiting column 3 207 is slidably provided on the mounting frame 201. The limiting column 3 207 is inserted into the rotating shaft of the gear 1 202 to lock the gear 1 202. An inclined block 208 is provided at the lower end of the limiting column 3 207. When the mounting frame 201 is close to the air deflector 102, the limiting rod 105 is inserted into the inclined block 208, and the limiting rod 105 pushes the inclined block 208 slides on the mounting frame 201, the inclined block 208 drives the limiting column three 207 to move, and the limiting column three 207 is pulled out from the gear one 202, releasing the lock on the gear one 202. At this time, the gear one 202 rotates through the deformation recovery force of the torsion spring. The lower end of the mounting frame 201 is provided with multiple sets of deformation rods 204. The deformation rods 204 and the asynchronous motor 101 are made of shape memory alloy. When the surface of the asynchronous motor 101 is overheated, the deformation rods 204 are deformed and drive the mounting frame 201 close to the air guide cover 102, thereby realizing the driving of the mounting frame 201. A second limiting post 206 is provided on the changing rod 204, and the second limiting post 206 is inserted into the cooling plate 205. The cooling plate 205 is slidably mounted on the asynchronous motor 101. A third spring 209 is provided between the cooling plate 205 and the asynchronous motor 101. The cooling plate 205 cools the surface of the asynchronous motor 101. When the deformation rod 204 moves, the second limiting post 206 is driven to move. The second limiting post 206 is pulled out of the cooling plate 205. The cooling plate 205 is reset by the deformation restoring force of the third spring 209. The emergency component 2 also includes multiple groups of rotationally mounted on the deflector 102 Upper gear 203, gear 203 is connected to the connecting buckle 106 through a thin rope, one end of the thin rope is wrapped around gear 203, and the other end of the thin rope is connected to the connecting buckle 106. When the mounting bracket 201 is close to the air deflector 102, gear 1 202 is engaged with gear 2 203. When the limiting column 3 207 is pulled out from gear 1 202, gear 1 202 drives gear 2 203 to rotate, and gear 2 203 drives the thin rope to be wrapped around gear 2 203. The thin rope pulls the deflector 104 to rotate on the air deflector 102, pulling the deflector 104 to the maximum working angle.

[0034] The air intake assembly 3 includes a filter plate 301 installed on the air guide cover 102. When the asynchronous motor 101 is cooled, the air passes through the filter plate 301 and enters the asynchronous motor 101. The filter plate 301 filters the air. An adjusting block 1 302 is slidably provided on the filter plate 301. A scraper 303 is provided on the adjusting block 1 302. An inclined surface is provided on both sides of the scraper 303. The scraper 303 scrapes off the debris on the surface of the filter plate 301 to reduce the probability of blockage of the filter plate 301. An adjusting block 2 305 is slidably provided on the scraper 303. A swing rod 306 is rotatably provided on the adjusting block 2 305. A dredging head 307 is provided on the swing rod 306. The dredging head 307 is connected to the swing rod 306 through a spline shaft. When the filter hole on the filter plate 301 is blocked, the adjusting block 2 305 is driven to slide on the scraper 303. The second cam 308 is provided on both sides of the scraper 303, and the cam 308 is fitted with the knocking plate 304, and the cam 308 is driven to rotate, and the cam 308 drives the knocking plate 304 to slide back and forth on the scraper 303, and the knocking plate 304 knocks the filter plate 301, knocking off the dust on the surface of the filter plate 301.

[0035] Working principle: When the asynchronous motor 101 is working, the heat dissipation shaft 107 rotates synchronously. When the heat dissipation shaft 107 rotates, it drives the fan blades 108 to rotate. When the fan blades 108 rotate, the inside of the asynchronous motor 101 is cooled. Under low temperature conditions, the wind fanned by the fan blades 108 is discharged through the air outlet 116, and a minimum working angle is formed between the guide plate 104 and the air guide cover 102. At this time, the wind flowing naturally completes the heat dissipation of the asynchronous motor 101.

[0036] When the speed of the asynchronous motor 101 becomes higher, the heat generated by the asynchronous motor 101 becomes larger and needs to be dissipated quickly, driving the baffle 103 to move, and the baffle 103 closes the air outlet 116. At this time, the airflow fanned out by the fan blades 108 is discharged through the chamber 2 118 and the chamber 1 117 to dissipate heat for the asynchronous motor 101, and at the same time, the speed of the heat dissipation shaft 107 is increased. When the speed of the heat dissipation shaft 107 becomes faster, the centrifugal force exerted on the trigger block 109 becomes larger, and the greater the distance between the trigger block 109 and the axis of the heat dissipation shaft 107, the trigger block 109 pushes the support column 111 to slide on the air guide cover 102, and the support column 111 pushes the guide plate 104 to rotate on the air guide cover 102, and the support column 111 drives the limit hole 112 to move, and the support column 111 pushes the limit column 113, and the limit column 113 is inserted into different limit holes 112 to fix the support column 111. The guide plate 104 is fixed to ensure the stability of the deployment of the guide plate 104. The guide plate 104 forms a trumpet-shaped acceleration air duct, which increases the air volume passing through the surface of the asynchronous motor 101 shell and improves the heat dissipation efficiency of the asynchronous motor 101 shell. When the asynchronous motor 101 completes heat dissipation, the speed of the heat dissipation shaft 107 decreases. At this time, the trigger block 109 is reset by the deformation recovery force of the spring 110. When the trigger block 109 is not in contact with the support column 111 for a long time, the reset rod 115 is driven to slide on the air deflector 102. The reset rod 115 drives the reset block 119 to move. The reset block 119 pulls the limit column 113 to move. The reset block 119 pulls the limit column 113 out of the limit hole 112. At this time, the limit column 113 releases the fixation of the support column 111, and the support column 111 is reset by gravity. At the same time, the guide plate 104 is reset to the minimum working angle by gravity to avoid energy waste.

[0037] When the temperature of the housing of the asynchronous motor 101 is too high but the speed of the heat dissipation shaft 107 does not increase due to other reasons such as failure, and the guide plate 104 cannot be driven, the housing 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 recovers its shape due to heat, and the deformation rod 204 drives the mounting frame 201 to approach the guide cover 102. At the same time, the deformation rod 204 drives the limiting column 206 to be pulled out from the cooling plate 205. The limiting column 206 releases the limit on the cooling plate 205. At this time, the cooling plate 205 is reset by the deformation recovery force of the spring 3 209. The cooling plate 205 quickly fits with the asynchronous motor 101, and the cooling plate 205 cools down the asynchronous motor 101. The mounting frame 201 Drive gear 1 202 close to the air deflector 102, and gear 1 202 engages with gear 2 203. At the same time, the limiting rod 105 pushes the inclined block 208 to slide on the mounting frame 201. The inclined block 208 drives the limiting column 3 207 to move. The limiting column 3 207 releases the lock on gear 1 202. Gear 1 202 is reset and rotated by the torsion spring. Gear 1 202 drives gear 2 203 to rotate. Gear 2 203 wraps the thin rope around gear 2 203. Gear 2 203 drives the guide plate 104 to rotate, and adjusts the guide plate 104 to the maximum working angle, forming a trumpet-shaped acceleration air duct to dissipate heat from the casing of the asynchronous motor 101. At the same time, an alarm reminds the staff to overhaul the asynchronous motor 101 and restore the rotation speed of the heat dissipation shaft 107.

[0038] The gas dissipated by 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 is debris on the surface of the filter plate 301, the regulating block 1 302 is driven to slide on the filter plate 301. The regulating block 1 302 drives the scraper 303 to move. The scraper 303 scrapes the debris on the surface of the filter plate 301. When the filter holes on the filter plate 301 are blocked, the regulating block 2 305 is driven to slide on the scraper 303. The regulating block 2 305 drives the swing rod 306 to move, and drives the swing rod 306 to rotate on the regulating block 2 305. The swing rod 306 drives the dredging head 307 to clear the blockage. The holes of the plugs are aligned. After alignment, the dredging head 307 is driven to slide on the swing rod 306, and the dredging head 307 is inserted into the hole blocked by the filter plate 301. The dredging head 307 is driven to rotate, and the dredging head 307 dredges the blocked holes. Knocking plates 304 are slidably provided on both sides of the scraper 303, and a spring four 309 is provided between the knocking plate 304 and the scraper 303. Cams 308 are also provided on both sides of the scraper 303. The cams 308 are fitted with the knocking plates 304, and the cams 308 are driven to rotate. The cams 308 drive the knocking plates 304 to slide back and forth on the scraper 303, and the knocking plates 304 knock on the filter plate 301, knocking off the dust on the surface of the filter plate 301.
