Description

Technical Field

[0001] This invention belongs to the field of ducted fan technology, specifically relating to an intelligent temperature control and heat dissipation system for the stator of an internal rotor motor. Background Technology

[0002] During operation, the stator of a ducted fan motor generates a significant amount of heat due to factors such as resistive losses from current flowing through the windings, eddy current and hysteresis losses in the core caused by the alternating magnetic field, and mechanical friction. If this heat cannot be dissipated in time and accumulates, it will cause accelerated aging of the stator insulation material, a significant decrease in motor operating efficiency, and in severe cases, stator burnout, directly affecting the stable operation and service life of the motor. Therefore, a dedicated cooling system is required for the stator of a ducted fan motor.

[0003] Currently available ducted fan motor stator cooling systems still have many technical defects in practical use, specifically: 1. The connection between the heat dissipation system and the duct is mostly fastened with bolts. The installation process requires multiple alignments and bolt tightening, which is cumbersome and greatly reduces the efficiency of the heat dissipation system installation and disassembly, making it inconvenient for later maintenance and repair. 2. The cooling system has a fixed cooling capacity, resulting in a consistently consistent cooling effect that cannot be adaptively adjusted based on the actual temperature of the motor stator. When the motor stator temperature is high and enhanced cooling is required, the existing system cannot improve cooling efficiency; when the motor stator temperature is low and only basic cooling is needed, the fixed cooling structure generates additional air resistance, increasing the motor's energy consumption. 3. The existing heat dissipation system has a simple air intake structure design, which cannot help increase the amount of air entering for heat dissipation, thus limiting the heat dissipation efficiency. At the same time, the air intake shroud is prone to shaking and displacement due to air resistance during operation, resulting in poor positioning stability and further affecting the stability of the heat dissipation effect.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention replaces the traditional bolt fastening method with the elastic snap-fit ​​structure of the movable positioning part. The operator only needs to pull the movable positioning pin to complete the alignment of the duct connection part with the duct. After releasing, the movable positioning pin automatically snaps into the groove of the duct under the action of the helical spring, realizing quick positioning and fixing, which greatly improves the connection efficiency between the heat dissipation system and the duct, and facilitates the disassembly and maintenance in the later stage. 2. This invention achieves real-time detection of the motor stator temperature through the cooperation of a temperature sensor and controller in the temperature control and heat dissipation unit. Based on the temperature detection results, the controller precisely controls the rotation angle of the servo motor's output shaft, thereby adjusting the air intake angle of the folding air intake cover. When the motor stator temperature rises, the rotation angle of the folding air intake cover is increased to improve air intake and heat dissipation efficiency; when the motor stator temperature decreases, the rotation angle of the folding air intake cover is decreased. This reduces air resistance and motor energy consumption while ensuring basic heat dissipation, achieving adaptive intelligent adjustment of the heat dissipation effect. 3. The auxiliary limiting part of the present invention has dual functions of increasing air intake and secondary limiting: When the electric telescopic rod extends, the triangular pusher pushes the auxiliary air intake ring to slide, expanding the air intake diameter of the folding air intake cover, assisting in increasing the amount of cooling air entering, and further improving the heat dissipation efficiency; at the same time, the output shaft of the electric telescopic rod is inserted into the limiting hole of the arc-shaped positioning frame to perform secondary limiting on the folding air intake cover after angle adjustment, effectively counteracting the effect of air resistance on the folding air intake cover, preventing it from shaking or shifting, and improving the structural stability of the folding air intake part; when the electric telescopic rod retracts, the auxiliary air intake ring is automatically stored in the folding air intake cover under the action of the return spring, avoiding additional resistance in the non-working state; 4. The heat dissipation shell of the present invention adopts a serpentine heat dissipation hole design, which extends the heat exchange path of the heat dissipation medium and improves the heat exchange efficiency. At the same time, the flexible and bendable characteristics of the heat dissipation hose perfectly match the angle adjustment of the folding air inlet, ensuring the sealing and continuity of the heat dissipation medium flow, and ensuring that the heat dissipation system can achieve efficient heat dissipation at any adjustable angle.

[0019] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0020] The following is in conjunction with the appendix Figures 1-10 The intelligent temperature control and heat dissipation system for the internal rotor motor stator of the present invention will be described in further detail.

[0021] The intelligent temperature control and heat dissipation system for the internal rotor motor stator of this invention is applied to the field of ducted fan technology. Addressing the technical shortcomings of existing ducted fan motor stator heat dissipation systems, such as cumbersome installation, inability to adaptively adjust heat dissipation, insufficient air intake, and poor stability of the air intake shroud, this invention achieves rapid assembly and disassembly of the heat dissipation system, adaptive adjustment of heat dissipation, and stable and efficient operation of the air intake structure through the structural coordination and intelligent control of the duct connection part 100, movable positioning part 200, folding air intake part 300, auxiliary limiting part 400, and temperature control and heat dissipation part 500. The specific structure, connection relationship, and working principle of each component are explained below.

[0022] The duct connection 100 serves as the basic connection carrier between the entire heat dissipation system and the duct, and also provides installation support for the movable positioning part 200 and the folding air intake part 300. It includes a duct connection ring 101 and eight arc-shaped positioning brackets 102. The outer diameter of the duct connection ring 101 is adapted to the inner diameter of the duct to ensure the coaxiality and fit of the duct connection ring 101 and the duct after assembly, and to avoid leakage of heat dissipation medium or structural shaking due to assembly gaps. The eight arc-shaped positioning brackets 102 are evenly distributed and fixed on the inner wall of the duct connection ring 101. Each arc-shaped positioning bracket 102 has a row of limiting round holes 1021. The limiting round holes 1021 provide a plug-in positioning structure for the output shaft of the electric telescopic rod 404 of the subsequent auxiliary limiting part 400, so as to realize secondary limiting of the folding air intake part 300.

[0023] Two sets of movable positioning parts 200 are symmetrically installed on the inner wall of the duct connecting ring 101 of the duct connecting part 100. Their core function is to replace the traditional bolt fastening method, realize the quick positioning and fixing of the heat dissipation system and the duct, improve the efficiency of disassembly and assembly, and provide convenience for later maintenance and repair.

[0024] Each set of movable positioning parts 200 includes a U-shaped positioning seat 201, a movable positioning pin 202, a support anti-detachment ring 203, and a coil spring 204. The U-shaped positioning seat 201 is fixedly installed on the inner wall of the duct connecting ring 101, providing sliding support and guidance for the movable positioning pin 202, ensuring its linear extension and retraction. The movable positioning pin 202 slides through the duct connecting ring 101 and the U-shaped positioning seat 201, and its outer end is chamfered to facilitate quick alignment with a pre-set groove on the duct. The interlocking design reduces the difficulty of assembly alignment; the support anti-detachment ring 203 is fixedly sleeved on the outside of the movable positioning pin 202, and the outer side of the support anti-detachment ring 203 abuts against the inner wall of the duct connecting ring 101, effectively preventing the movable positioning pin 202 from falling off the duct connecting ring 101 and ensuring structural integrity; the helical spring 204 is sleeved on the outside of the movable positioning pin 202, and its two ends abut against the U-shaped positioning seat 201 and the support anti-detachment ring 203 respectively, providing elastic restoring force for the movable positioning pin 202.

[0025] During assembly, the worker pulls the movable positioning pin 202 inward, compressing the helical spring 204. After the duct connecting ring 101 is fitted into the duct, the worker releases the movable positioning pin 202. Under the elastic restoring action of the helical spring 204, the movable positioning pin 202 automatically extends outward and engages in the groove of the duct, completing the quick fixation of the duct connecting part 100 and the duct. During disassembly, the worker only needs to pull the movable positioning pin 202 inward again to release the limit, greatly improving the efficiency of connecting and disassembling the heat dissipation system and the duct.

[0026] Four sets of folding air intakes 300 are evenly distributed around the duct connecting rings 101 of the duct connecting part 100. They are the core components for adjusting the air intake angle for heat dissipation. The air intake angle can be adjusted according to the actual temperature of the motor stator, thereby improving heat dissipation efficiency, reducing unnecessary air resistance, and reducing motor energy consumption.

[0027] Each set of folding air intakes 300 includes two rectangular mounting blocks 301, a circular mounting shaft 302, a folding air intake shroud 303, and two servo motors 304. The two rectangular mounting blocks 301 are symmetrically fixed to the duct connecting ring 101, providing stable rotational support for the circular mounting shaft 302. The circular mounting shaft 302 is rotatably mounted between the two rectangular mounting blocks 301, serving as the rotational carrier for the folding air intake shroud 303 and providing a basis for its angle adjustment. The folding air intake shroud 303 is fixedly sleeved on the outside of the circular mounting shaft 302 and is connected to the two rectangular mounting blocks. The 301 contacts ensure the sealing of the folding air intake shroud 303 when it rotates. The folding air intake shroud 303 is equipped with a heat dissipation connector 3031, which serves as a flow connection channel for the heat dissipation medium and achieves a sealed connection with the heat dissipation hose 502 of the temperature control heat dissipation unit 500. Two servo motors 304 are fixed one-to-one on two rectangular mounting blocks 301, and their output shafts are fixedly connected to the circular mounting shaft 302, providing precise power output for the rotation of the circular mounting shaft 302, realizing stepless adjustment of the rotation angle of the folding air intake shroud 303, and ensuring the accuracy of the air intake angle adjustment.

[0028] The auxiliary limiting part 400 is set in four sets, which are installed one by one with the four sets of folding air intake parts 300. It has the dual functions of assisting in increasing the air intake volume and limiting the folding air intake parts 300 for a second time. It not only solves the problem of insufficient air intake volume of the existing heat dissipation system, but also effectively prevents the folding air intake cover 303 from shaking or shifting due to air resistance during operation, thus improving the structural stability.

[0029] Each set of auxiliary limiting parts 400 includes an auxiliary air intake ring 401, two return springs 402, a rectangular mounting base 403, two electric telescopic rods 404, and two triangular pushers 405. The auxiliary air intake ring 401 is slidably sleeved on the folding air intake hood 303, with rounded corners at its outer ends. This reduces resistance in the airflow channel and expands the air intake diameter of the folding air intake hood 303 when extended, effectively increasing the amount of cooling air entering. The outer ends of the two return springs 402 are fixedly connected to the folding air intake hood 303, and their inner ends are fixedly connected to the auxiliary air intake ring 401, providing elastic return force for the auxiliary air intake ring 401 and enabling automatic retraction of the auxiliary air intake ring 401. The rectangular mounting base 403 is fixed inside the folding air intake hood 303, providing support for the two electric telescopic rods 404. Stable installation support; two electric telescopic rods 404 are symmetrically fixed on both sides of the rectangular mounting base 403, and their output shafts slide through the folding air intake cover 303. The outer end of the output shaft is chamfered to facilitate quick alignment and insertion with the limiting round hole 1021 on the arc-shaped positioning frame 102. The output shaft of the electric telescopic rod 404 is adapted to the limiting round hole 1021 to achieve secondary limiting of the folding air intake part 300 after angle adjustment. Two triangular push frames 405 are fixed one-to-one on the output shaft of the two electric telescopic rods 404 and abut against the inner wall of the auxiliary air intake ring 401. The inclined structure of the triangular push frame 405 converts the linear telescopic motion of the electric telescopic rod 404 into the axial sliding motion of the auxiliary air intake ring 401, so as to achieve the precise extension and retraction of the auxiliary air intake ring 401.

[0030] When increased air intake is required, the output shaft of the electric telescopic rod 404 extends outward, driving the triangular pusher 405 to move outward synchronously. The inclined surface of the triangular pusher 405 pushes the auxiliary air intake ring 401 to slide outward along the folded air intake cover 303, expanding the air intake diameter and increasing the amount of cooling air entering. At the same time, the output shaft of the electric telescopic rod 404 inserts into the corresponding limiting hole 1021 of the arc-shaped positioning frame 102, providing secondary limiting for the folded air intake cover 303 after angle adjustment, counteracting the effect of air resistance and preventing it from shaking. Offset; When no additional increase in air intake is required, the output shaft of the electric telescopic rod 404 retracts inward, the triangular pusher 405 releases the push on the auxiliary air intake ring 401, and the auxiliary air intake ring 401 automatically retracts into the folding air intake cover 303 under the elastic reset action of the reset spring 402, avoiding the generation of additional air resistance in the non-working state. At the same time, the output shaft of the electric telescopic rod 404 is pulled out from the limiting round hole 1021, releasing the secondary limit on the folding air intake cover 303, which facilitates the angle adjustment of the folding air intake cover 303.

[0031] The temperature control and heat dissipation unit 500 is installed on the duct connection unit 100 and the four sets of folding air intake units 300. It is the intelligent control core and heat dissipation execution core of the entire system. It can not only efficiently dissipate heat from the motor stator, but also intelligently control the rotation angle of the folding air intake unit 300 and the working state of the auxiliary limit unit 400 according to the real-time temperature of the motor stator, so as to achieve adaptive adjustment of the heat dissipation effect.

[0032] The temperature control and heat dissipation unit 500 includes a heat dissipation housing 501, a heat dissipation hose 502, a controller 503, and a temperature sensor 504. The heat dissipation housing 501 is located inside the duct and is attached to the motor stator. It has serpentine heat dissipation holes inside, matching the number of holes in the folded air intake section 300. These serpentine holes extend the flow path of the heat dissipation medium inside the heat dissipation housing 501, increasing heat exchange time and significantly improving heat exchange efficiency. The heat dissipation housing 501 is fixedly equipped with inlet and outlet pipes 5011, each corresponding to one end of the serpentine heat dissipation holes, providing a dedicated channel for the entry and exit of the heat dissipation medium. One end of the heat dissipation hose 502 is sealed to the inlet and outlet pipes 5011 on one side of the heat dissipation housing 501, and the other end corresponds to the heat dissipation connector 3031 of the folded air intake section 300. The sealed connection and flexible, bendable heat dissipation hose 502 perfectly adapt to any angle adjustment of the folded air intake 300, ensuring the sealing and continuity of the heat dissipation medium flow and ensuring efficient heat dissipation of the heat dissipation system at any adjustment angle. The controller 503 is fixed to the inner wall of the duct connecting ring 101 and is electrically connected to the servo motor 304 and the electric telescopic rod 404. As the intelligent control core of the entire system, it can receive the temperature detection signal from the temperature sensor 504 and output precise action control commands according to the preset temperature threshold. The temperature sensor 504 is installed on the heat dissipation housing 501 and electrically connected to the controller 503. It is used to detect the operating temperature of the motor stator in real time and convert the temperature signal into an electrical signal and transmit it to the controller 503.

[0033] In summary, the intelligent temperature control and heat dissipation system for the internal rotor motor stator of this invention achieves the overall technical effects of rapid assembly and disassembly, intelligent temperature control, efficient heat dissipation, and structural stability through the coordinated operation of various components. Its complete workflow is as follows: System assembly: The staff pulls the movable positioning pins 202 of the two sets of movable positioning parts 200 inward, puts the duct connecting ring 101 into the duct, and then releases the movable positioning pins 202. Under the elastic reset action of the spiral spring 204, the movable positioning pins 202 are inserted into the duct groove, completing the quick fixation of the heat dissipation system and the duct, replacing the traditional bolt fastening and improving assembly efficiency. Temperature detection: When the motor stator is working, the temperature sensor 504 detects its temperature in real time and continuously transmits the temperature electrical signal to the controller 503; Low temperature operation: When the motor stator temperature is lower than the low temperature threshold preset by the controller 503, the controller 503 controls the servo motor 304 to drive the folding air intake cover 303 to rotate to a small angle state, only ensuring basic air intake and heat dissipation; at the same time, it controls the electric telescopic rod 404 of the auxiliary limit part 400 to retract, and the auxiliary air intake ring 401 is stored in the folding air intake cover 303 to reduce air resistance and reduce motor energy consumption; High-temperature operating conditions: When the motor stator temperature exceeds the preset high-temperature threshold of the controller 503, the controller 503 first controls the servo motor 304 to drive the folding air intake cover 303 to rotate to a large angle, increasing the air intake angle and improving the basic air intake volume; then, it controls the output shaft of the electric telescopic rod 404 to extend outward, pushing the auxiliary air intake ring 401 to slide and expand the air intake diameter, further increasing the amount of cooling air entering. At the same time, the output shaft of the electric telescopic rod 404 is inserted into the limiting round hole 1021 of the arc-shaped positioning frame 102 to perform secondary limiting on the folding air intake cover 303, preventing it from shaking due to air resistance; the heat dissipation medium enters the serpentine heat dissipation hole of the heat dissipation housing 501 through the heat dissipation joint 3031 and the heat dissipation hose 502 of the folding air intake cover 303, and after completing heat exchange with the high-temperature motor stator, it is discharged from the intake and exhaust pipes 5011, achieving efficient heat dissipation; Temperature stabilization: When the motor stator temperature drops to within the preset threshold range, the controller 503 reverses the control of the electric telescopic rod 404 to retract, the auxiliary air intake ring 401 automatically retracts, and at the same time controls the servo motor 304 to drive the folding air intake cover 303 to rotate to a moderate angle, so as to balance air resistance and energy consumption while ensuring heat dissipation. System disassembly and maintenance: When maintenance and repair are required in the future, the staff only need to pull the movable positioning pin 202 inward to quickly release the limit of the heat dissipation system and duct, and complete the disassembly. The operation is convenient.

[0034] This invention addresses several technical deficiencies in existing ducted fan motor stator cooling systems by combining structural optimization with intelligent control. The various technical features work together synergistically to improve heat dissipation efficiency and structural stability, while also enabling rapid disassembly and assembly of the cooling system and adaptive adjustment of the heat dissipation effect. This effectively extends the service life of the motor stator and enhances the overall operational stability of the ducted fan motor.
