Description

Technical Field

[0001] This invention relates to the field of motor protection technology, and in particular to a motor cooling device. Background Technology

[0002] An electric motor is a core device that converts electrical energy into mechanical energy, widely used in industrial production, transportation, household appliances, and many other fields. During operation, the motor generates heat due to factors such as resistance losses from current flowing through the windings, eddy current losses and hysteresis losses in the iron core under alternating magnetic fields, and friction between mechanical parts. If this heat cannot be dissipated in time, the internal temperature of the motor will continue to rise. When the temperature exceeds the tolerance limit of the motor's insulation material, the insulation performance will drop sharply, leading to insulation damage and causing serious faults such as inter-turn short circuits and phase-to-phase short circuits. This not only shortens the motor's service life but may also cause equipment downtime, production interruptions, and even safety accidents.

[0003] A search revealed that Chinese utility model patent CN222423396U discloses a servo motor cooling device for an electric kiln furnace, comprising: a servo motor; a cooling shell 1 and a cooling shell 2 fitted to the side wall of the servo motor; threaded grooves at the bottom of both cooling shell 1 and cooling shell 2; a cooling fan threadedly connected to the inner wall of the threaded grooves; cooling pipes evenly arranged inside the cavities of cooling shell 1 and cooling shell 2; an external pipe 1 connected to the top end of each cooling pipe; an external pipe 2 connected to the tail end of each cooling pipe; a plurality of heat dissipation holes 1 at the top end of both cooling shell 1 and cooling shell 2; and a plurality of heat dissipation holes 2 at the bottom end of both cooling shell 1 and cooling shell 2. The cooling system combines air cooling and water cooling through the design of cooling shell one, cooling shell two, radiator fan, external pipe one, external pipe two, and cooling pipes to improve cooling efficiency. The design also features threaded grooves, threaded connecting rings, retaining ring one, and retaining ring two, resulting in a simple structure, high assembly efficiency, and easy disassembly. However, in practical use, this solution still has the following shortcomings: The aforementioned cooling device needs to be customized to the specific size of the motor to achieve sufficient contact area with the motor surface for effective cooling. However, motors come in various sizes, and their casings usually have heat dissipation grilles rather than being smooth cylinders. Therefore, the aforementioned device cannot be effectively applied to different motor models or to the outer walls of motors with different shapes, making it difficult to guarantee the cooling effect. Furthermore, the water-cooling pipes are densely distributed, and all of them exchange heat with the motor. This results in a sufficiently low liquid temperature at the water inlet of the water-cooling system to effectively dissipate heat. However, as the system moves further, the liquid temperature at the rear end has increased, reducing its heat dissipation effect on the motor. Consequently, the heat cannot be evenly dissipated from all parts of the motor, which can easily lead to localized overheating at the water-cooled tail end.

[0004] Therefore, this application provides a motor cooling device to meet the needs of adapting to different motor models and providing uniform and effective cooling. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a motor cooling device to solve the problems of poor adaptability of cooling devices and uneven cooling.

[0006] To achieve the above objectives, the present invention provides a motor cooling device, comprising a housing unit and a cooling unit; The shell unit includes two symmetrically arranged mounting components. Each mounting component includes an arc-shaped frame one and an arc-shaped frame two hinged to the arc-shaped frame one.

A circular arc groove is provided on the side wall of both the arc-shaped frame one and the arc-shaped frame two. The cooling unit includes a plurality of cooling components arranged in a ring array between two mounting components. Each cooling component includes a slider slidably mounted in the arc groove. A mounting plate is provided between two opposing sliders. The mounting plate has a groove arranged radially along the arc frame. A sliding plate is slidably mounted in the groove. A heat-conducting plate is fixedly mounted at the end of the sliding plate away from the mounting plate. A limit component is provided between the sliding plate and the groove. An adjustment component is provided between the slider and the mounting plate. The heat-conducting plate is provided with a filling component, and both the arc-shaped frame one and the arc-shaped frame two are provided with air-cooling components; The filling assembly includes storage slots symmetrically formed at both ends of the heat-conducting plate along its length. A sealing plate is hinged to the storage slot. A through hole is formed at the top of the storage slot. A capillary hole is formed at the bottom of the storage slot. A flexible ring is fixedly installed at the bottom of the heat-conducting plate. A pressure plate is slidably installed inside the storage slot. A pressure rod is fixedly installed on the pressure plate, extending out of the through hole and slidably connected thereto. An operating plate is fixedly installed at one end of the pressure rod extending out of the through hole.

[0007] Preferably, the heat-conducting plate has liquid cooling holes along its length, and a liquid cooling pipe is provided on the heat-conducting plate, the liquid cooling pipe passing through a plurality of the liquid cooling holes in sequence.

[0008] Preferably, the limiting component includes a plurality of ratchet teeth arranged in a linear array and symmetrically fixedly installed on the inner sidewall of the slide groove. A relief groove is symmetrically opened on the top of the sidewall of the slide plate. A pawl adapted to the ratchet teeth is slidably installed in the relief groove. A spring is fixedly installed between the pawl and the relief groove.

[0009] Preferably, the pawl has inclined portions on both sides of the end away from the relief groove, which are in contact with the inclined surface of the ratchet, and the angle of the inclined portion at the top is smaller than the angle of the inclined portion at the bottom.

[0010] Preferably, the adjustment assembly includes a telescopic groove formed on the top of the mounting plate, and connecting rods are symmetrically slidably installed in the telescopic groove. One end of the connecting rod extending out of the telescopic groove is fixedly connected to the slider.

[0011] Preferably, the bottom of the pressure plate is provided with spikes.

[0012] Preferably, the air-cooling component includes an arc-shaped plate with a rotating groove. A semi-circular fan-shaped plate is slidably installed in the rotating groove. A plurality of fan blades arranged in a ring array are fixedly installed on one end of the fan-shaped plate near the heat-conducting plate. A positioning groove is provided on the side wall of the fan-shaped plate, and a positioning pin is fixedly installed on the side wall of the fan-shaped plate. A plurality of ventilation holes arranged in a ring array are provided on the fan-shaped plate. The first arc-shaped frame and the second arc-shaped frame are respectively fixedly connected to the two arc-shaped plates, and the two fan-shaped plates arranged opposite each other are centrally symmetrical.

[0013] Preferably, a semi-toothed ring is fixedly installed at one end of the fan-shaped plate away from the heat-conducting plate, and a telescopic rod is rotatably installed on the arc-shaped plate that is fixedly connected to the two arc-shaped frames. Both ends of the telescopic rod are fixedly installed with gears that mesh with the semi-toothed ring.

[0014] A method for cooling and reducing the temperature of an electric motor includes the following steps: Step 1: Drag the arc-shaped frame 1 and arc-shaped frame 2 at both ends along the telescopic groove to extend or shorten the connecting rod, and adjust the distance between the two ends and the motor so as to fix it on motors of different sizes. Step 2: Operate arc frame one and arc frame two, and use their hinges to rotate and open them to form an opening that can be nested to the outer periphery of the motor. Align the opened device with the outside of the motor, and then rotate the hinges to reset, thereby surrounding the motor. Slide the slider to drive the mounting plate to move, thereby adjusting the position of the heat-conducting plate and the motor. Step 3: Pull the heat-conducting plate outward along the slide groove through the sliding plate, so that it fits against the motor. Pull the heat-conducting plate radially downward, so that the sliding plate drives the pawl to move downward. The inclined part at the bottom of the pawl contacts the inclined surface of the ratchet tooth. The pawl moves inward to the inside of the relief groove and resets under the action of the spring. When the heat-conducting plate moves to contact the outer wall of the motor, the inclined part at the top of the pawl limits the sliding plate. When it is necessary to remove the device, pull the heat-conducting plate upward with force. The pawl is retracted and reset through the action between the inclined part at the top of the pawl and the ratchet tooth. Step 4: After the heat-conducting plate contacts the outer wall of the motor, press the operating plate to drive the pressure rod and pressure plate to move downward. The storage tank contains bagged thermal paste. When the pressure plate moves downward, the spikes pierce the packaging. Under the action of the pressure plate, the thermal paste is squeezed outward along the capillary pores. Under the action of the flexible ring in full contact with the outer wall of the motor, the thermal paste is restricted to flow evenly between the heat-conducting plate and the outer wall of the motor, filling the uneven parts at the contact point. Step 5: Position one end of the sector plate at the motor output shaft and connect the sector plate to the output shaft via a coupling. The opposing sector plates together form a ring, which is linked by a positioning pin and a positioning groove. When the motor is working, the output shaft rotates, causing the sector plate to rotate along the rotation groove, which in turn causes the fan blades to rotate and blow air, cooling the motor and the exposed liquid cooling pipes. The gears are driven by the semi-gear ring, and the fan blades at both ends of the motor rotate synchronously through the transmission action of the telescopic rod.

[0015] The beneficial effects of this invention are: 1. This type of motor cooling device, by setting up two arc-shaped frames, opens by rotating the hinge to form an opening, can be easily nested into the outer periphery of the motor. After alignment, it can be reset to surround the motor, greatly facilitating the installation and disassembly of the cooling device and improving the flexibility of use. By sliding the slider to drive the mounting plate, the corresponding position of the heat-conducting plate and the motor can be flexibly adjusted to adapt to the outer surface of different motor models. By increasing the heat conduction area, the heat conduction effect is enhanced, improving the cooling capacity. Pressing the operating plate drives the pressure rod and pressure plate to move downward. After the bagged thermal paste in the storage tank is punctured by the spikes, it is squeezed outward along the capillary under the action of the pressure plate. The flexible ring makes full contact with the outer wall of the motor, which can restrict the thermal paste to flow evenly between the heat-conducting plate and the outer wall of the motor, filling the uneven parts of the contact area, maximizing the heat dissipation area, and improving the cooling effect.

[0016] 2. This type of motor cooling device, by setting a telescopic groove and connecting rod, can adjust the distance between the two end mounting components and adjust the overall length of the equipment, making it easy to fix and install on motors of different sizes. The heat-conducting plate can be pulled out along the slide groove via a sliding plate to fit the motor, realizing the adaptation to motors of different sizes and improving the adaptability and versatility of the equipment.

[0017] 3. This type of motor cooling device improves the cooling speed of the heat-conducting plate by setting liquid cooling pipes through the heat-conducting plate. The part of the liquid cooling pipes extending out of the heat-conducting plate can fully contact the air, achieving rapid cooling under the action of the air-cooling components. This avoids the problem of poor local heat dissipation at the tail end of the water-cooled system. When the motor is working, the relatively set fan-shaped plates form a ring and move synchronously, driving the fan blades to rotate and blow air, which cools the motor and the exposed liquid cooling pipes. Through the transmission action of the semi-tooth ring and gears, the fan blades at both ends of the motor rotate synchronously and the air direction is the same, forming a stable air path and improving the cooling effect.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figures 1 to 9As shown, a motor cooling device includes a housing unit and a cooling unit. The housing unit includes two symmetrically arranged mounting components. Each mounting component includes an arc-shaped frame 1 and an arc-shaped frame 2 hinged to the arc-shaped frame 1. A fixing plate 21 is fixedly mounted at the other end of both the arc-shaped frame 1 and the arc-shaped frame 2. The fixing plate 21 has fixing holes 22. Arc grooves 3 are formed on the side walls of both the arc-shaped frame 1 and the arc-shaped frame 2. The cooling unit includes several cooling components arranged in a circular array between the two mounting components. Each cooling component includes a slider 31 slidably mounted within the arc groove 3. Between two opposing sliders 31... An installation plate 32 is provided, and a groove 33 is provided on the installation plate 32 radially along the arc frame 1. A slide plate 34 is slidably installed in the groove 33. A heat-conducting plate 35 is fixedly installed at the end of the slide plate 34 away from the installation plate 32. A limit component is provided between the slide plate 34 and the groove 33. An adjustment component is provided between the slider 31 and the installation plate 32. A filling component is provided on the heat-conducting plate 35. Both the arc frame 1 and the arc frame 2 are provided with air-cooling components. Liquid cooling holes 36 are provided along the length of the heat-conducting plate 35. Liquid cooling pipes 37 are provided on the heat-conducting plate 35 and pass through several liquid cooling holes 36 in sequence. In use, the arc-shaped frame 1 and arc-shaped frame 2 are rotated open at the hinge to form an opening that can be nested around the motor. After aligning with the outside of the motor, the hinge is rotated back to its original position, surrounding the motor. The mounting plate 32 is moved by the sliding slider 31 to adjust the position of the heat-conducting plate 35 relative to the motor, thereby finding a suitable smooth surface or embedding the heat-conducting plate 35 into the motor's heat sink, thus enhancing its heat conduction effect and improving cooling capacity. The overall length of the equipment can be adjusted by adjusting the components. The heat-conducting plate 35 is moved along the slide plate 34. The slide 33 extends outward to fit the motor, enabling adaptation to motors of different sizes and improving the adaptability and versatility of the equipment. Furthermore, the cooling device can be easily installed and disassembled by rotating the arc-shaped frame 1 and arc-shaped frame 2, increasing the flexibility of use. The liquid cooling pipe 37 passes through the heat-conducting plate 35, which can improve the heat dissipation and cooling speed of the heat-conducting plate 35. The part of the liquid cooling pipe 37 that extends out of the heat-conducting plate 35 can fully contact the air and achieve rapid cooling under the action of the air-cooling components. This allows the coolant to cool down before it comes into contact with the heat-conducting plate 35 again, avoiding the problem of poor local heat dissipation at the tail end of the water cooling system.

[0024] like Figures 3 to 5As shown, the limiting component includes a number of ratchet teeth 4 symmetrically fixedly installed on the inner side wall of the slide groove 33 in a linear array. The top of the side wall of the slide plate 34 is symmetrically provided with a clearance groove 41. A pawl 42 adapted to the ratchet teeth 4 is slidably installed in the clearance groove 41. A spring 43 is fixedly installed between the pawl 42 and the clearance groove 41. Both sides of the end of the pawl 42 away from the clearance groove 41 are provided with inclined portions that contact the inclined surfaces of the ratchet teeth 4, and the angle of the inclined portion at the top is smaller than the angle of the inclined portion at the bottom. The adjusting component includes a telescopic groove 44 opened on the top of the mounting plate 32. A connecting rod 45 is symmetrically slidably installed in the telescopic groove 44. One end of the connecting rod 45 extending out of the telescopic groove 44 is fixedly connected to the slider 31. By pulling the heat-conducting plate 35 radially downward, the slide plate 34 causes the pawl 42 to move downward. At this time, the inclined part at the bottom of the pawl 42 contacts the inclined surface of the ratchet 4, causing the pawl 42 to move inward into the relief groove 41 and reset under the action of the spring 43. When the heat-conducting plate 35 moves to contact the outer wall of the motor, the inclined part at the top of the pawl 42 has a small angle, which can limit the sliding plate 34. When it is necessary to remove the device, the heat-conducting plate 35 can be pulled upward by force, and the retraction and reset can be achieved through the action between the inclined part with a small angle and the ratchet 4. In the length direction, the distance between the two end mounting components can be adjusted by the action of the connecting rod 45 in the telescopic groove 44, so as to facilitate the fixed installation on motors of different sizes.

[0025] like Figure 4 , Figure 6 , Figure 7 As shown, the filling assembly includes storage tanks 5 symmetrically opened at both ends of the heat-conducting plate 35 along its length. A sealing plate 51 is hinged to the storage tank 5. A through hole 52 is opened at the top of the storage tank 5, and a capillary hole 53 is opened at the bottom of the storage tank 5. A flexible ring 54 is fixedly installed at the bottom of the heat-conducting plate 35. A pressure plate 55 is slidably installed inside the storage tank 5. A pressure rod 56 is fixedly installed on the pressure plate 55, extending out of the through hole 52 and slidably connected thereto. An operating plate 57 is fixedly installed at one end of the pressure rod 56 extending out of the through hole 52. A spike 58 is provided at the bottom of the pressure plate 55. After the heat-conducting plate 35 contacts the outer wall of the motor, the pressure rod 56 and the pressure plate 55 can be moved downward by pressing the operating plate 57. The storage tank 5 contains a bag of thermal conductive paste. After the packaging is punctured by the spike 58, the thermal conductive paste is squeezed outward along the capillary pores 53 under the action of the pressure plate 55. Under the action of the flexible ring 54 in full contact with the outer wall of the motor, the thermal conductive paste is restricted to flow evenly between the heat-conducting plate 35 and the outer wall of the motor. The thermal conductive paste can fill the uneven parts of the contact area to maximize the heat dissipation area and improve the cooling effect. By placing a replaceable bag of thermal conductive paste in the storage tank 5, the thermal conductive paste can be well preserved and is easy to reuse.

[0026] like Figure 1 , Figure 8 and Figure 9 As shown, the air-cooled assembly includes an arc-shaped plate 6, a rotating groove 61 on the arc-shaped plate 6, a semi-circular fan-shaped plate 62 slidably installed in the rotating groove 61, a plurality of fan blades 63 arranged in a ring array fixedly installed on the end of the fan-shaped plate 62 near the heat-conducting plate 35, a positioning groove 64 on the side wall of the fan-shaped plate 62, a positioning pin 65 fixedly installed on the side wall of the fan-shaped plate 62, and a plurality of ventilation holes 66 arranged in a ring array on the fan-shaped plate 62; wherein, arc-shaped frame 1 and arc-shaped frame 2 are fixedly connected to two arc-shaped plates 6 respectively, and the two fan-shaped plates 62 arranged opposite each other are centrally symmetrical; a semi-toothed ring 7 is fixedly installed on the end of the fan-shaped plate 62 away from the heat-conducting plate 35, and a telescopic rod 71 is rotatably installed on the arc-shaped plate 6 fixedly connected to the two arc-shaped frames 1, and gears 72 that mesh with the semi-toothed ring 7 are fixedly installed at both ends of the telescopic rod 71; The length of the adjustment device is such that one end of the sector plate 62 is located at the motor output shaft, and the sector plate 62 can be connected to the output shaft via a coupling. When the motor is working, the relatively arranged sector plates 62 together form a ring, and are linked by the positioning pin 65 and the positioning groove 64 to achieve synchronous movement. When the output shaft rotates, it drives the sector plate 62 to rotate along the rotation groove 61, which drives the fan blades 63 to rotate and blow air, which cools the motor and the exposed liquid cooling pipe 37. Through the transmission action of the semi-tooth ring 7 and the gear 72, the fan blades 63 at both ends of the motor rotate synchronously, and the air guiding direction at both ends is the same, so that the motor presents a stable air path along its length, improving the cooling effect.

[0027] A method for cooling and reducing the temperature of an electric motor includes the following steps: Step 1: Drag the arc-shaped frame 1 and arc-shaped frame 2 at both ends along the telescopic groove 44 to both sides to extend or shorten the connecting rod 45, and adjust the distance between the two ends and the motor so as to fix it on motors of different sizes. Step 2: Operate the arc frame 1 and arc frame 2, and use their hinges to rotate and open them to form an opening that can be nested to the outer periphery of the motor. Align the opened device with the outside of the motor, and then rotate the hinges to reset, thereby surrounding the motor. Slide the slider 31 to drive the mounting plate 32 to move, thereby adjusting the position of the heat conduction plate 35 corresponding to the motor. Step 3: Pull the heat-conducting plate 35 outward along the slide groove 33 via the sliding plate 34, so that it fits against the motor. Pull the heat-conducting plate 35 radially downward, so that the sliding plate 34 drives the pawl 42 to move downward. The inclined part at the bottom of the pawl 42 contacts the inclined surface of the ratchet 4. The pawl 42 moves inward toward the relief groove 41 and resets under the action of the spring 43. When the heat-conducting plate 35 moves to contact the outer wall of the motor, the inclined part at the top of the pawl 42 limits the sliding plate 34. When it is necessary to remove the device, pull the heat-conducting plate 35 upward with force. The pawl 42 is retracted and reset through the action between the inclined part at the top of the pawl 42 and the ratchet 4. Step 4: After the heat-conducting plate 35 contacts the outer wall of the motor, press the operating plate 57 to drive the pressure rod 56 and the pressure plate 55 to move downward. The storage tank 5 contains a bag of thermal paste. When the pressure plate 55 moves downward, the spike 58 punctures the packaging. Under the action of the pressure plate 55, the thermal paste is squeezed outward along the capillary pores 53. Under the action of the flexible ring 54 in full contact with the outer wall of the motor, the thermal paste is restricted to flow evenly between the heat-conducting plate 35 and the outer wall of the motor, filling the uneven parts at the contact point. Step 5: Position the sector plate 62 at one end of the motor output shaft and connect the sector plate 62 to the output shaft via a coupling. The opposing sector plates 62 together form a ring, which is linked by the positioning pin 65 and the positioning groove 64. When the motor is working, the output shaft rotates, which drives the sector plate 62 to rotate along the rotation groove 61, thereby driving the fan blades 63 to rotate and blow air, which cools the motor and the exposed liquid cooling pipe 37. The gear 72 is driven by the half-tooth ring 7, and the fan blades 63 at both ends of the motor rotate synchronously through the transmission action of the telescopic rod 71.

[0028] The technical solution provided by this invention involves rotating and opening the arc-shaped frame 1 and arc-shaped frame 2 at the hinge, creating an opening that can be nested around the outer periphery of the motor. After aligning them with the outside of the motor, rotating the hinge returns them to their original position, thus surrounding the motor. The sliding slider 31 drives the mounting plate 32 to adjust the position of the heat-conducting plate 35 relative to the motor, thereby finding a suitable smooth surface or embedding the heat-conducting plate 35 into the motor's heat sink, enhancing its heat conduction effect and improving cooling capacity. Pulling the heat-conducting plate 35 radially downwards... The sliding plate 34 drives the pawl 42 to move downwards. At this time, the inclined part at the bottom of the pawl 42 contacts the inclined surface of the ratchet 4, causing the pawl 42 to move inwards towards the relief groove 41 and reset under the action of the spring 43. When the heat-conducting plate 35 moves to contact the outer wall of the motor, the inclined part at the top of the pawl 42 has a small angle, which can limit the sliding plate 34. When it is necessary to remove the device, the heat-conducting plate 35 can be pulled upwards by force, and the retraction and reset can be achieved through the action between the inclined part with a small angle and the ratchet 4. The device is retracted and reset in the length direction through the telescopic groove. The connecting rod 45 inside 44 adjusts the distance between the two mounting components, facilitating installation on motors of different sizes. By pulling the heat-conducting plate 35 outwards along the slide groove 33 via the sliding plate 34 to fit the motor, it adapts to motors of different sizes, improving the equipment's adaptability and versatility. Furthermore, the cooling device can be easily installed and removed by rotating the arc-shaped frame 1 and arc-shaped frame 2, increasing its flexibility. The liquid cooling pipe 37 passing through the heat-conducting plate 35 increases the speed of heat dissipation and cooling, and the liquid cooling pipe 37 extending beyond the heat-conducting plate 35... The part can fully contact the air. When the motor is working, the oppositely arranged sector plates 62 together form a ring and are linked by the positioning pin 65 and the positioning groove 64 to achieve synchronous movement. When the output shaft rotates, it drives the sector plates 62 to rotate along the rotation groove 61, which drives the fan blades 63 to rotate and blow air, which cools the motor and the exposed liquid cooling pipe 37. Under the effect of improving the cooling and temperature reduction, the temperature is reduced rapidly, so that the coolant is cooled before it comes into contact with the heat conduction plate 35 again, avoiding the problem of poor local heat dissipation at the tail end of the water cooling system.

9. A method for cooling an electric motor, based on the electric motor cooling device according to any one of claims 1-8, characterized in that, Includes the following steps: Step 1: Drag the arc-shaped frame 1 (1) and arc-shaped frame 2 (2) at both ends along the telescopic groove (44) to both sides to make the connecting rod (45) extend or shorten, adjust the distance between the two ends and the motor, so as to fix it on motors of different sizes; Step 2: Operate the arc frame one (1) and arc frame two (2), and use their hinge to rotate and open them to form an opening that can be nested to the outer periphery of the motor. Align the opened device with the outside of the motor, and then rotate the hinge to reset it, thereby surrounding the motor. Slide the slider (31) to drive the mounting plate (32) to move, thereby adjusting the position of the heat conduction plate (35) corresponding to the motor. Step 3: Pull the heat-conducting plate (35) outward along the slide groove (33) through the slide plate (34) so ​​that it fits against the motor. Pull the heat-conducting plate (35) radially downward so that the slide plate (34) drives the pawl (42) to move downward. The inclined part at the bottom of the pawl (42) contacts the inclined surface of the ratchet (4). The pawl (42) moves towards the inside of the relief groove (41) and resets under the action of the spring (43). When the heat-conducting plate (35) moves to contact the outer wall of the motor, the inclined part at the top of the pawl (42) limits the slide plate (34). When it is necessary to remove the device, pull the heat-conducting plate (35) upward with force. The pawl (42) retracts and resets through the action between the inclined part at the top of the pawl (42) and the ratchet (4). Step 4: After the heat-conducting plate (35) contacts the outer wall of the motor, press the operating plate (57) to drive the pressure rod (56) and the pressure plate (55) to move downward. The storage tank (5) contains bagged thermal paste. When the pressure plate (55) moves downward, the spike (58) punctures the packaging. Under the action of the pressure plate (55), the thermal paste is squeezed outward along the capillary pores (53). Under the action of the flexible ring (54) in full contact with the outer wall of the motor, the thermal paste is restricted to flow evenly between the heat-conducting plate (35) and the outer wall of the motor, filling the uneven parts at the contact point. Step 5: Position the sector plate (62) at one end of the motor output shaft and connect the sector plate (62) to the output shaft through a coupling. The sector plates (62) set opposite each other form a ring. The linkage is achieved through the positioning pin (65) and the positioning groove (64). When the motor is working, the output shaft rotates, which drives the sector plate (62) to rotate along the rotation groove (61), thereby driving the fan blades (63) to rotate and blow air, which cools the motor and the exposed liquid cooling pipe (37). The gear (72) is driven to move through the half-tooth ring (7), and the fan blades (63) at both ends of the motor rotate synchronously through the transmission action of the telescopic rod (71).
