Description
Technical Field
[0001] This invention relates to the field of motor technology, and in particular to a motor heat dissipation structure, a motor, a motor heat dissipation method, and an air conditioner. Background Technology
[0002] With the advancement of technology and the improvement of people's living standards, air conditioners, as important household appliances for regulating ambient temperature, have increasingly higher requirements for performance and safety. In modern air conditioning technology, air conditioners use fans to drive airflow through heat exchangers to change the temperature of ambient air. The motor generates heat during the fan operation, and when the motor temperature is too high, its performance often deteriorates, leading to a decrease in motor speed. Prolonged motor overheating can also cause uneven airflow, insufficient capacity, and a shortened motor lifespan. Therefore, motor heat dissipation has always been a key factor affecting the performance and stability of air conditioners. Currently, air conditioners typically use natural cooling or air cooling to dissipate heat from the motor motor. Air cooling often involves opening ventilation holes on the motor casing, through which the motor exchanges heat with the ambient air to cool down. However, this cooling method is inefficient and requires large ventilation holes on the casing, yet it cannot completely solve the problem of motor overheating, greatly limiting motor performance. Furthermore, in the event of a motor fire, these ventilation holes continuously supply oxygen to the ignition point, which can exacerbate the fire.
[0003] Therefore, it is necessary to improve the existing motor cooling methods to overcome the shortcomings of the existing technology. Summary of the Invention
[0004] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a motor heat dissipation structure. This structure can introduce external water into the solution chamber through a water inlet, thereby using a heat dissipation sleeve to dissipate heat from the motor, achieving efficient heat dissipation of the motor, thereby improving motor efficiency and extending the motor's service life.
[0005] A motor heat dissipation structure, comprising:
[0006] A heat dissipation sleeve is disposed on the outer wall of the motor. A solution chamber is disposed in the heat dissipation sleeve, and a water inlet is disposed on the heat dissipation sleeve, which is connected to the solution chamber.
[0007] A driving structure drives the heat dissipation sleeve to move, thereby connecting or disconnecting the water inlet component from the water storage device.
[0008] The drive structure can move the heat sink. Through this movement, the water inlet can be connected to or disconnected from the water storage device. When the water inlet is connected to the water storage device, water in the water storage device can be introduced into the solution chamber; when the water inlet is disconnected from the water storage device, the introduction of water stops.
[0009] In practical applications, the water storage device can be connected to the condensate drainage system of an air conditioner, thus utilizing the condensate generated during air conditioner operation as a heat dissipation liquid. When the motor is running, the drive structure drives the heat dissipation jacket to move, connecting the water inlet to the water storage device, and the condensate is introduced into the solution chamber. As the condensate flows in the solution chamber, the motor's heat is effectively carried away, achieving efficient heat dissipation for the motor, thereby improving motor efficiency and extending motor life.
[0010] In a preferred embodiment of the present invention, the heat dissipation sleeve is further provided with a drain outlet, a drain plug is snapped into the drain outlet, and a first snap-fit member is provided on one side of the drain plug.
[0011] When the drive structure drives the heat sink to a set position, the first snap-fit component engages with the second snap-fit component at the set position; and the drive structure drives the heat sink to rotate, causing the drain plug to open at the drain outlet.
[0012] In actual operation, when it is necessary to clean or replace the solution inside the heat sink, the operator only needs to use the control system to drive the structure to move the heat sink to the set position. At this time, the first and second locking components engage, and as the heat sink rotates, the drain plug automatically opens, allowing the solution inside the heat sink to drain smoothly. After cleaning or replacement is completed, the heat sink is reset through the corresponding operation, and the drain plug will close accordingly, ensuring the normal operation of the heat sink.
[0013] In a preferred embodiment of the present invention, an elastic structure is provided between the heat dissipation sleeve and the drain plug, and the elastic force generated by the elastic structure makes the drain plug fit tightly against the drain outlet.
[0014] The elastic structure can be a damping structure, which ensures that the drain plug remains tightly attached to the drain outlet when no external force is applied, thereby preventing the liquid in the solution chamber from leaking.
[0015] In a preferred embodiment of the present invention, the drive structure includes a drive device, a gear, a crank, and a connecting shaft. The crank is fixed to the output end of the drive device, and the gear is fixed to the end of the crank away from the drive device.
[0016] The gear has an internal threaded hole, which is arranged along the axis of the gear; the connecting shaft is sequentially connected to a first threaded section, a toothless section, and a second threaded section, with the first threaded section meshing with the internal threaded hole; the heat dissipation sleeve is provided with a support block, and the support block is provided with a support rail, with the second threaded section engaging with the support rail;
[0017] The driving device drives the gear to rotate, so that the gear drives the heat sink to move along the axial direction of the connecting shaft through the connecting shaft.
[0018] In actual operation, when the drive unit starts, it drives the crank to rotate, which in turn drives the gear to rotate. Since the gear and the first threaded section of the connecting shaft are meshed, the rotation of the gear is converted into linear motion of the connecting shaft. Furthermore, because the second threaded section of the connecting shaft engages with the support rail on the heat sink, the heat sink moves along with the movement of the connecting shaft.
[0019] Precise control of the heat sink's position can be achieved through the drive mechanism and gear transmission. This precise control not only helps improve heat dissipation efficiency but also prevents the heat sink from colliding with the drive mechanism or other components, thereby extending the equipment's lifespan.
[0020] In a preferred embodiment of the present invention, the crank has a first end and a second end disposed opposite to each other. The first end is provided with a limiting boss that engages with the gear, and the second end is provided with a connecting hole, which is fixedly connected to the output shaft of the drive device.
[0021] In a preferred embodiment of the present invention, the heat sink is further provided with a threaded guide rail, and the length direction of the threaded guide rail is arranged on the heat sink in a direction perpendicular to the axis of the connecting shaft.
[0022] A limiting ring is provided between the toothless section and the second threaded section, and the limiting ring protrudes outward from the surface of the connecting shaft; when the heat dissipation sleeve moves, it drives the threaded guide rail to move closer to or away from the gear;
[0023] When the threaded guide rail is engaged with the gear and they mesh together; when the gear rotates, it drives the heat dissipation sleeve to move along the length direction of the threaded guide rail.
[0024] The limiting ring functions when the gear moves to the toothless section, axially limiting the gear, at which point the gear engages with the threaded guide rail on the heat sink sleeve. As the gear continues to rotate, the engagement between the gear and the threaded guide rail causes the heat sink sleeve to move along the length of the threaded guide rail. This movement of the heat sink sleeve can be used to seal the heat dissipation holes on the motor's bottom casing, providing fire resistance to the motor.
[0025] In a preferred embodiment of the present invention, the water storage device is provided with a valve, the bottom of the valve is provided with a limiting seat, a spring is provided on one side of the limiting seat, one end of the spring is connected to the limiting seat, and the other end is connected to the mounting base.
[0026] When the drive structure drives the heat dissipation sleeve to move, one end of the water inlet can push open the limiting seat, thereby making the valve connected to the water inlet.
[0027] The design of the spring and limit seat ensures a tight seal of the valve under normal conditions, preventing accidental water leakage and enhancing system safety. When heat dissipation is required, the drive structure moves the heat dissipation sleeve, and the water inlet quickly pushes open the limit seat to open the valve, ensuring that water flows into the heat dissipation sleeve in a timely manner for rapid heat dissipation. Through the interaction between the water inlet and the limit seat, the valve opens and closes automatically without manual operation, improving the system's automation level.
[0028] In a preferred embodiment of the present invention, a water receiving device is provided below the heat dissipation sleeve, and a second snap-fit component is provided on the water receiving device.
[0029] After the first and second connectors engage, when the drive structure drives the heat sink to rotate, the drain plug is opened at the drain outlet, thereby connecting the drain outlet with the water receiving device.
[0030] When the drain plug is opened at the drain outlet, the drain outlet is connected to the inside of the water receiving device, and the liquid discharged from the heat dissipation jacket can flow smoothly into the water receiving device, avoiding liquid leakage and waste.
[0031] The second objective of this invention is to provide an electric motor, which is provided with the electric motor heat dissipation structure described above.
[0032] A third objective of this invention is to provide a heat dissipation method for an electric motor, implemented based on the electric motor described above;
[0033] The heat dissipation method includes:
[0034] Obtain the actual temperature T1 of the motor and determine whether T1 is greater than or equal to t1.
[0035] When T1≥t1, the drive structure is activated, connecting the water inlet to the water storage device; when T1<t1, the drive structure is not activated.
[0036] After the solution chamber is filled with water, the water temperature T2 in the solution chamber is detected, and it is determined whether T2 is greater than or equal to t2.
[0037] When T2≥t2, the solution in the chamber is released and the chamber is refilled with water; if T2<t2, the original state is maintained.
[0038] This method achieves intelligent management of the heat dissipation process by monitoring the motor temperature and the cooling system water temperature in real time and automatically controlling them according to preset thresholds. Furthermore, it activates and adjusts the cooling system based on the motor's actual cooling needs, ensuring the motor always operates within a safe temperature range, thus improving heat dissipation efficiency and extending the motor's lifespan.
[0039] In a preferred embodiment of the present invention, it further includes:
[0040] The motor includes a base housing with heat dissipation holes. In the event of a fire, the heat dissipation sleeve is moved by the drive structure to cover the heat dissipation holes. The heat dissipation sleeve is disposed on the outer wall of the base housing, and its shape is adapted to the shape of the motor's base housing. The movement of the heat dissipation sleeve is a rotation along the outer wall of the base housing to cover the heat dissipation holes.
[0041] In this embodiment, when a fire is detected inside the motor, the drive structure immediately activates, causing the heat sink to move rapidly and cover the heat dissipation holes. This action cuts off the path for the fire to spread outward through the heat dissipation holes, thereby controlling the fire and preventing its further expansion. Furthermore, by covering the heat dissipation holes, the heat sink isolates the motor from the air, preventing outside air from entering the ignition point, thus extinguishing the fire.
[0042] The fourth objective of this invention is to provide an air conditioner, wherein the air conditioner is equipped with a motor as described above;
[0043] The air conditioner is also equipped with a water storage device, which is used to collect the condensate from the air conditioner.
[0044] The water storage device effectively collects the condensate from the air conditioner. The collected condensate can be used for various purposes, such as replenishing the water supply in the cooling system, or being reused in other places where water is needed, thereby improving the efficiency of water resource utilization.
[0045] Furthermore, because the air conditioner integrates the aforementioned high-efficiency cooling motor, it can maintain stable performance during long-term operation, reducing the risk of performance degradation or malfunction due to motor overheating. This design not only extends the lifespan of the air conditioner but also enhances the user experience.
[0046] The beneficial effects of this invention are as follows:
[0047] This invention provides a motor heat dissipation structure, comprising a heat dissipation sleeve and a drive structure. The heat dissipation sleeve is disposed on the outer wall of the motor, and a solution chamber is provided within the heat dissipation sleeve. A water inlet is disposed on the heat dissipation sleeve, and the water inlet communicates with the solution chamber. The drive structure drives the heat dissipation sleeve to move, thereby connecting or disconnecting the water inlet from a water storage device. In practical applications, the heat dissipation sleeve is tightly disposed on the outer wall of the motor to ensure good heat conduction. The solution chamber inside the heat dissipation sleeve is used to contain a heat-dissipating liquid, such as water or coolant. In practical applications, the water storage device can be connected to the condensate drainage system of an air conditioner, thereby utilizing the condensate generated during air conditioner operation as a heat-dissipating liquid. When the motor is running, the drive structure drives the heat dissipation sleeve to move, connecting the water inlet to the water storage device, and the condensate is introduced into the solution chamber. As the condensate flows in the solution chamber, the heat of the motor is effectively carried away, achieving efficient heat dissipation of the motor. Overall, this heat dissipation structure can achieve efficient heat dissipation of the motor by introducing condensate into the solution chamber of the heat dissipation sleeve. The low-temperature characteristics of the condensate allow it to quickly absorb the heat of the motor, thereby reducing the operating temperature of the motor. Because the motor temperature is effectively controlled, the internal resistance of the motor is reduced, and the loss when current passes through is reduced, thereby improving the operating efficiency of the motor and extending its service life.
[0048] This application also provides an electric motor including the above-mentioned heat dissipation structure and a cooling method for the motor. The method can select the cooling method according to the operating conditions of the motor, flexibly dissipate heat from the motor, and effectively control the temperature of the motor, thereby improving the operating efficiency of the motor and extending the service life of the motor.
[0049] This application also provides an air conditioner including the aforementioned motor, which can use the condensate produced by the air conditioner as a heat dissipation liquid to cool the motor, which not only saves water resources and realizes the reuse of wastewater, but also enables the motor to operate at a high efficiency for a long time, and the air conditioner can also maintain good performance and stability.

[0063] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0064] With the advancement of technology and the improvement of people's living standards, air conditioners, as an important household appliance for regulating ambient temperature, have increasingly higher requirements for performance and safety. In modern air conditioning technology, air conditioners use a fan to drive impellers, causing ambient air to pass through a heat exchanger to change the temperature of the air. The motor generates heat during the process of driving the impellers. When the motor temperature is too high, its performance often deteriorates, leading to a decrease in motor speed. Prolonged motor overheating can also cause uneven airflow, insufficient capacity, and a shortened motor lifespan. Therefore, motor heat dissipation has always been a key factor affecting the performance and stability of air conditioners. Currently, air conditioners typically use natural cooling or air cooling to dissipate heat from the motor motor. Air cooling often involves opening ventilation holes on the motor casing, through which the motor exchanges heat with the ambient air to cool down. However, this cooling method is inefficient and requires large ventilation holes on the casing, yet it cannot completely solve the problem of motor overheating, greatly limiting motor performance.
[0065] Based on this, this application provides a motor heat dissipation structure.
[0066] Example 1
[0067] like Figures 1-8 As shown, this embodiment provides a motor heat dissipation structure, including:
[0068] A heat dissipation sleeve 1 is disposed on the outer wall of the motor 10. A solution chamber 11 is disposed in the heat dissipation sleeve 1. A water inlet 13 is disposed on the heat dissipation sleeve 1 and the water inlet 13 is connected to the solution chamber 11. The solution chamber 11 can be used to store cryogenic liquid.
[0069] The driving structure 2 drives the heat dissipation sleeve 1 to move, so that the water inlet 13 is connected to or disconnected from the water storage device.
[0070] Specifically, the structure of the heat sink 1 is designed according to the shape of the outer wall of the motor 10 so that the heat sink 1 is tightly installed on the outer wall of the motor 10 to ensure good heat conduction. More specifically, the heat sink 1 can be made of an alloy material so that the liquid in the solution chamber 11 can cool the motor 10 through the heat sink 1.
[0071] The drive structure 2 can drive the heat sink 1 to move. Through this movement, the water inlet 13 can be connected to or disconnected from the water storage device. When the water inlet 13 is connected to the water storage device, water in the water storage device can be introduced into the solution chamber 11; when the water inlet 13 is disconnected from the water storage device, the introduction of water stops.
[0072] In practical applications, the water storage device can be connected to the condensate drainage system of an air conditioner, thereby utilizing the condensate generated during air conditioner operation as a heat dissipation liquid. When the motor 10 is running, the drive structure 2 drives the heat dissipation sleeve 1 to move, connecting the water inlet 13 to the water storage device, and the condensate is introduced into the solution chamber 11. As the condensate flows in the solution chamber 11, the heat of the motor 10 is effectively carried away, achieving efficient heat dissipation of the motor 10, thereby improving motor efficiency and extending motor life.
[0073] Furthermore, in a preferred embodiment, the heat dissipation structure may also be equipped with a temperature sensor and a control system to monitor the temperature of the motor 10 in real time and automatically adjust the movement of the heat sink 1 and the amount of condensate introduced as needed, thereby ensuring that the motor 10 always operates within a safe temperature range.
[0074] When this heat dissipation structure is used to cool the motor of an air conditioner, it can utilize the condensate produced by the air conditioner as the cooling liquid. This not only saves water resources but also enables wastewater reuse, aligning with the principles of environmental protection and sustainable development. It should be noted that when using the condensate as the cooling liquid, the condensate can be filtered through a water storage device to improve its cleanliness.
[0075] Example 2
[0076] This embodiment is an improvement on embodiment 1.
[0077] In this embodiment, the heat dissipation sleeve 1 is also provided with a drain outlet, and a drain plug 12 is snapped into the drain outlet. A first snap-fit member 121 is provided on one side of the drain plug 12.
[0078] When the driving structure 2 drives the heat sink 1 to a set position, the first latching member 121 engages with the second latching member 31 at the set position, and the driving structure 2 drives the heat sink 1 to rotate, thereby opening the drain plug 12 at the drain outlet. It should be noted that this set position is determined according to the size of the heat sink structure and the application scenario; the set position may differ in different application scenarios.
[0079] In one specific embodiment, the drive structure 2 of this application can both drive the heat sink 1 to move and drive the heat sink 1 to rotate. For example, the drive structure 2 of this application may include a drive motor and a connecting shaft. When the heat sink 1 has not moved to the set position, the drive motor drives the connecting shaft to move along the axis of the connecting shaft. This can be achieved by setting a threaded section on the connecting shaft and setting an internally threaded gear at the output end of the drive motor, with the threaded section of the connecting shaft connected to the internally threaded hole. During the movement of the heat sink 1, it gradually approaches the set position. The connecting shaft is provided with a toothless section. When the heat sink 1 reaches the set position, the toothless section of the connecting shaft is connected to the internally threaded hole. At this time, the drive motor driving the gear to rotate cannot drive the connecting shaft to continue moving. At the set position, a threaded guide rail that meshes with the external teeth of the gear can be provided. When the heat sink 1 reaches the set position, the toothless section of the connecting shaft is connected to the internally threaded hole, and the external teeth of the gear mesh with the threaded guide rail. Therefore, when the drive motor drives the gear to rotate, the heat sink 1 can be driven to rotate along the extension direction of the threaded guide track, so that the first snap-fit member 121 and the second snap-fit member 31 move away from each other, and the drain plug 12 is opened at the drain outlet.
[0080] In actual operation, when it is necessary to clean or replace the solution inside the heat sink 1, the operator only needs to use the control system command to drive the structure 2 to move the heat sink 1 to the set position. At this time, the first latch 121 and the second latch 31 engage. Then, the heat sink can be rotated by the drive structure, so that the first latch 121 and the second latch 31 move away from each other, thereby automatically opening the drain plug 12 and allowing the solution in the solution chamber 11 to drain smoothly. After cleaning or replacement is completed, the heat sink 1 is reset by the corresponding operation, and the drain plug 12 will close accordingly, ensuring the normal operation of the heat sink 1.
[0081] In a preferred embodiment of this invention, an elastic structure is provided between the heat dissipation sleeve 1 and the drain plug 12, and the elastic force generated by the elastic structure makes the drain plug 12 fit tightly against the drain outlet.
[0082] The elastic structure can be a damping structure, which ensures that the drain plug 12 remains tightly attached to the drain outlet when no external force is applied, thereby preventing liquid leakage from the solution chamber 11. The drain plug 1 is hinged to the heat dissipation sleeve 1, and the damping structure is located at the hinge point, so that the drain outlet remains closed when the drain plug 1 is not subjected to external force.
[0083] This application achieves the automatic opening and closing function of the drain plug 12 through the design of a first card connector 121, a second card connector 31, and a drive structure 2 to drive the heat sink 1 to rotate. When the heat sink 1 moves to a set position, the drain plug 12 is opened by the rotation of the heat sink 1 driven by the drive structure 2; when the heat sink 1 returns to its original position, the drain plug 12 automatically closes. This design greatly improves the convenience and automation of operation.
[0084] In addition, the drain plug 12 can tightly seal the drain outlet when drainage is not required, effectively preventing solution leakage. This not only ensures the normal operation of the heat sink 1, but also avoids safety issues that may be caused by solution leakage.
[0085] Example 3
[0086] This embodiment is an improvement on embodiment 1.
[0087] In this embodiment, the drive structure 2 includes a drive device 24, a gear 22, a crank 23 and a connecting shaft 21. The crank 23 is fixed to the output end of the drive device 24, and the gear 22 is fixed to the end of the crank 23 away from the drive device 24.
[0088] The gear 22 has an internal threaded hole 221, which is arranged along the axis of the gear 22. The connecting shaft 21 is sequentially connected with a first threaded section 213, a toothless section 212, and a second threaded section 211. The first threaded section 213 meshes with the internal threaded hole 221. The heat dissipation sleeve 1 is provided with a support block 14, and the support block 14 is provided with a support rail 141. The second threaded section 211 engages with the support rail 141. Specifically, after the second threaded section 211 of the connecting shaft 21 engages with the support rail 141, the connecting shaft 21 and the support block 14 are fixed to each other. Therefore, when the connecting shaft 21 moves, the heat dissipation sleeve 1 will be driven by the connecting shaft 21 and move along the axis of the connecting shaft 21.
[0089] Specifically, the second threaded segment 211 is fixed to the support rail 141 by its own thread. Alternatively, a limiting block can be set on the second threaded segment 211 and a limiting groove can be set on the support block 14. The limiting block is engaged with the limiting groove to fix the second threaded segment 211 and the support block 14 to each other. Multiple support blocks 14 can be set on the heat dissipation sleeve 1 as needed.
[0090] The driving device 24 drives the gear 22 to rotate, so that the gear 22 drives the heat sink 1 to move along the axial direction of the connecting shaft 21 via the connecting shaft 21.
[0091] In actual operation, the drive device 24 can be a motor. When the drive device 24 is started, it drives the crank 23 to rotate, which in turn drives the gear 22 to rotate. Since the gear 22 and the first threaded section 213 of the connecting shaft 21 are meshed with each other, the rotation of the gear 22 is converted into the linear motion of the connecting shaft 21. Furthermore, since the second threaded section 211 of the connecting shaft 21 is engaged and fixed with the support rail 141 on the heat sink 1, the heat sink 1 will move as the connecting shaft 21 moves.
[0092] Through the precise transmission of the drive unit 24 and gear 22, the position of the heat sink 1 can be precisely controlled. This precise control not only helps improve heat dissipation efficiency but also prevents the heat sink 1 from colliding with the drive unit 24 or other components, thereby extending the service life of the equipment.
[0093] More specifically, in this embodiment, the crank 23 has a first end 231 and a second end 232 disposed opposite to each other. The first end 231 is provided with a limiting boss 2311 that engages with the gear 22, and the second end 232 is provided with a connecting hole 2321, which is fixedly connected to the output shaft of the drive device 24.
[0094] The crank 23 is engaged with the gear 22 via the limiting boss 2311, which is convenient for installation and can maintain the stability of the structure.
[0095] In this embodiment, the heat sink 1 is also provided with a threaded guide rail 15, and the length direction of the threaded guide rail 15 is arranged on the heat sink 1 in a direction perpendicular to the axis of the connecting shaft 21.
[0096] A limiting ring 214 is provided between the toothless section 212 and the second threaded section 211, and the limiting ring 214 protrudes outward from the surface of the connecting shaft 21. When the heat sink 1 moves, it drives the threaded guide rail 15 to move closer to or further away from the gear 22. When the threaded guide rail 15 is engaged with the gear 22, the rotation of the gear 22 drives the heat sink 1 to move along the length direction of the threaded guide rail 15. At this time, the toothless section 212 of the connecting shaft 21 engages with the internal threaded hole 221 of the gear 22. When the toothless section 212 is fully inserted into the internal threaded hole 221, one side of the gear 22 abuts against the limiting ring 214. It should be noted that the movement of the heat sink 1 along the length direction of the threaded guide rail 15 is a circumferential rotation of the heat sink.
[0097] The limiting ring 214 limits the movement of the connecting shaft 21 when it moves. When the limiting ring 214 of the gear 22 engages, the connecting shaft 21 cannot move along its own axis under the drive of the gear 22. At this time, the gear 22 will mesh with the threaded guide rail 15 on the heat sink 1. As the gear 22 continues to rotate, due to the meshing of the gear 22 with the threaded guide rail 15, the heat sink 1 will be driven to move along the length of the threaded guide rail 15. In practical applications, the movement of the heat sink 1 in this way can drive the heat sink 1 to move circumferentially along the motor housing, thus it can be used to seal the heat dissipation holes 101 on the bottom housing of the motor, providing fire resistance for the motor.
[0098] Example 4
[0099] This embodiment is an improvement on embodiment 2.
[0100] In this embodiment, the water storage device is equipped with a valve 4, and a limiting seat 41 is provided at the bottom of the valve 4. A spring 42 is provided on one side of the limiting seat 41. One end of the spring 42 is connected to the limiting seat 41, and the other end is connected to the mounting base. In practical applications, the water storage device is used to collect condensate from air conditioners.
[0101] When the drive structure 2 drives the heat dissipation sleeve 1 to move, one end of the water inlet 13 can push open the limiting seat 41, thereby making the valve 4 connected to the water inlet 13.
[0102] The design of spring 42 and limit seat 41 ensures a tight seal of the valve under normal conditions, preventing accidental water leakage and enhancing system safety. When heat dissipation is required, drive structure 2 drives heat dissipation sleeve 1 to move, and water inlet 13 quickly pushes open limit seat 41 to open the valve, ensuring that water flows into heat dissipation sleeve 1 in a timely manner for rapid heat dissipation. Through the interaction between water inlet 13 and limit seat 41, the valve can be automatically opened and closed without manual operation, improving the automation level of the system.
[0103] In a preferred embodiment of this invention, a water receiving device 102 is provided below the heat dissipation sleeve 1, and the second snap-fit member 31 is provided on the water receiving device 102; the position set in this application is the position when the first snap-fit member 121 is connected to the second snap-fit member 31 on the water receiving device 102.
[0104] When the first latching member 121 engages with the second latching member 31, and the driving structure 2 drives the heat sink 1 to rotate, the first latching member 121 and the second latching member 31 move away from each other, thereby opening the drain plug 12 at the drain outlet so that the drain outlet is connected to the water receiving device 102, and the water discharged from the drain outlet can also enter the water receiving device 102 and be collected.
[0105] When the drain plug 12 is opened at the drain outlet, the liquid discharged from the heat sink 1 can flow smoothly into the water receiving device 102, avoiding liquid leakage and waste.
[0106] The effective reception of the water by the water receiving device 102 enables the reuse or proper treatment of the discharged liquid, which meets environmental protection requirements and also avoids the pollution of the equipment environment by the discharged condensate.
[0107] Example 5
[0108] This embodiment provides an electric motor, which is equipped with the electric motor heat dissipation structure described above.
[0109] The motor 10 includes a base housing with heat dissipation holes 101 for air cooling. This heat dissipation structure effectively prevents excessive temperature rise during operation, thus extending the motor's lifespan. Specifically, the motor's base housing is based on existing technology.
[0110] The motor 10 achieves significantly improved heat dissipation performance through the combined use of the heat dissipation holes 101 and the motor heat dissipation structure. This design ensures that the motor 10 maintains a suitable operating temperature under various working conditions, thereby improving the motor's operational stability and reliability.
[0111] Example 6
[0112] This embodiment provides a method for heat dissipation of an electric motor, which is implemented based on the electric motor described above.
[0113] The heat dissipation method includes:
[0114] S100: Obtain the actual temperature T1 of motor 10, and determine whether T1 is greater than or equal to t1; the temperature of t1 can be 50 degrees Celsius.
[0115] S200. When T1≥t1, the drive structure 2 is activated, so that the water inlet 13 is connected to the water storage device; when T1<t1, the drive structure 2 is not activated.
[0116] S300. After the solution chamber 11 is filled with water, the water temperature T2 of the solution chamber 11 is detected, and it is determined whether T2 is greater than or equal to t2; the temperature of t2 can be 40 degrees Celsius.
[0117] S400. When T2≥t2, the solution in the solution chamber 11 is released and the solution chamber 11 is refilled with water; if T2<t2, the original state is maintained.
[0118] This method achieves intelligent management of the heat dissipation process by monitoring the motor temperature and the cooling system water temperature in real time and automatically controlling them according to preset thresholds. Furthermore, it starts and adjusts the cooling system based on the actual heat dissipation needs of the motor 10, ensuring that the motor 10 always operates within a safe temperature range, improving heat dissipation efficiency and helping to extend the motor's service life.
[0119] The following is a detailed explanation of how this method is applied to the heat dissipation of the motor 10 in an air conditioner:
[0120] like Figure 1 As shown. After the air conditioner starts and enters the cooling mode, it begins to monitor the temperature T1 of the motor 10. When the temperature T1 ≥ t1, the motor 10 starts, driving the gear 22 via the crank 23. The gear 22 then moves the connecting shaft 21 to the right through its internal threaded hole 221, simultaneously moving the solution chamber 11 to the right as well. After moving a distance d1, the water inlet 13 contacts the valve and moves the valve to the right. When it reaches position d2, the valve 4 opens, and some of the condensate in the water storage device enters the solution chamber 11 through the water inlet 13 and is stored there. At this time, the temperature of the solution chamber 11 drops and exchanges heat with the motor 10, achieving rapid cooling of the motor 10 and improving its efficiency. The motor 10 continues to run, and the air conditioner monitors the temperature of the solution chamber 11. This process can be achieved through a temperature probe installed on the heat sink 1. When the water temperature T1 in the solution chamber 11 is higher than t2, the drive device 24 starts and moves to the set position. During this process, the first locking member 121 engages with the second locking member 31 on the water receiving device 102. Then, the heat dissipation sleeve 1 is driven to rotate, causing the drain plug 12 to be pulled open from the drain outlet. At this time, the water in the solution chamber 11 is discharged and enters the water receiving device 102. After running for another 10 seconds, the motor 10 reverses and runs one revolution. At this time, the drain plug 12 returns to its original position, and the condensate continues to enter the solution chamber 11, and the cooling and heat exchange process is carried out again.
[0121] Example 7
[0122] In this embodiment, the heat dissipation method for the motor further includes:
[0123] The bottom shell of the motor 10 is provided with heat dissipation holes 101. When the motor 10 catches fire, the heat dissipation sleeve 1 is moved by the drive structure 2 so that the heat dissipation sleeve 1 covers the heat dissipation holes 101.
[0124] In this embodiment, when a fire is detected inside the motor 10, the drive structure 2 immediately activates, driving the heat sink 1 to move rapidly and cover the heat dissipation hole 101. Specifically, the heat sink 1 moves circumferentially along the outer casing of the motor 10. This action cuts off the path for the fire to spread outward through the heat dissipation hole 101, thereby controlling the fire and preventing its further spread. Furthermore, after the heat sink 1 covers the heat dissipation hole 101, it prevents air from entering the motor casing 10, thus extinguishing the fire.
[0125] Example 8
[0126] This embodiment provides an air conditioner, which is equipped with a motor 10 as described above;
[0127] The air conditioner is also equipped with a water storage device, which is used to collect the condensate from the air conditioner.
[0128] The water storage device effectively collects the condensate from the air conditioner. The collected condensate can be used for various purposes, such as replenishing the water supply in the cooling system, or being reused in other places where water is needed, thereby improving the efficiency of water resource utilization.
[0129] Furthermore, because the air conditioner integrates the aforementioned high-efficiency cooling motor, it can maintain stable performance during long-term operation, reducing the risk of performance degradation or malfunction due to motor overheating. This design not only extends the lifespan of the air conditioner but also enhances the user experience.
[0130] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0131] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
