Description

Technical Field

[0001] This utility model relates to the field of electric motor power technology, and in particular to an integrated cooling mechanism for electric motors and water pumps. Background Technology

[0002] In today's industrial sector, electric motors serve as the core power source for various types of equipment, and their performance and reliability are of paramount importance. Electric motor-driven water pumps play a crucial role in transporting liquids in numerous scenarios; however, existing cooling technologies for electric motor-driven water pumps present several pressing issues that require resolution.

[0003] Currently, motor-driven water pumps are relatively large in size, which not only occupies a significant amount of installation space and increases layout complexity, but also limits their application in environments with stringent space requirements. More importantly, the cooling effect is unsatisfactory. This is especially true for cooling the stator inside the motor. Since the stator generates a large amount of heat during motor operation, if it is not cooled effectively and promptly, the stator temperature will become excessively high, thus affecting the motor's performance and lifespan.

[0004] Existing cooling methods mostly focus on cooling the exterior of the motor, making it difficult to accurately meet the complex heating mechanisms and heat dissipation requirements of the internal stator. Traditional cooling structure designs cannot ensure that the coolant flows fully and evenly across all parts of the stator, resulting in frequent localized overheating. Therefore, a new design is needed for the existing motor-pump cooling structure. Utility Model Content

One end of the fixed support is connected to the stator support, and the other end is connected to the water pump support. The water pump support has a cavity, and the pump core is disposed within the cavity. The circulation pipe element connects the pump core to the heat dissipation cavity. Under the action of the motor assembly, the pump core drives the cooling medium through the circulation pipe element into the heat dissipation cavity, achieving circulation.

[0010] A further improvement to the above scheme is that two circulation pipe elements are provided, and the two circulation pipe elements are respectively connected to two alignment connectors for the entry and exit of cooling medium in the heat dissipation cavity.

[0011] A further improvement to the above solution is that one end of the fixed bracket is connected to the connecting panel, and the circulation pipe element is provided with a heat dissipation element, which is located on the outside of the fixed bracket for heat dissipation of the circulation pipe element.

[0013] A further improvement to the above scheme is that the stator element includes a stator frame and a stator winding, the stator frame is provided with multiple winding arms, and the stator winding is wound on the winding arms; the rotor element includes multiple rotor magnets, the rotor magnets are disposed on a rotor support and are opposite to the winding arms.

[0014] A further improvement to the above scheme is that an output connection end is provided at the end of the output connection shaft that is away from the coupling. The output connection end is used to connect to the output end of the motor and extends to the outside of the stator support.

[0027] like Figures 1-5As shown in one embodiment of this utility model, an integrated cooling mechanism for a motor and water pump is provided, including a motor assembly 1, a cooling circulation assembly 2, and a water pump assembly 3. The motor assembly 1 includes a stator support 11, a stator element 12, a rotor support 13, a rotor element 14, and an output connecting shaft 15. The stator support 11 has a connecting cavity 16, the output connecting shaft 15 is disposed in the connecting cavity 16, the rotor support 13 is disposed on the output connecting shaft 15, the stator support 11 has a heat dissipation cavity 17, the stator element 12 is disposed in the heat dissipation cavity 17 and connected to the stator support 11, and the rotor element 14 is disposed in the heat dissipation cavity 17 and connected to the stator support 11. On the rotor support 13, the rotor element 14 is opposite to the stator element 12. The cooling circulation assembly 2 includes a fixed support 21 and a circulation pipe element 22. The water pump assembly 3 includes a water pump support 31 and a pump core 32. One end of the fixed support 21 is connected to the stator support 11, and the other end is connected to the water pump support 31. The water pump support 31 is provided with a cavity, and the pump core 32 is disposed in the cavity. The circulation pipe element 22 is used to connect the pump core 32 to the heat dissipation cavity 17. Under the action of the motor assembly 1, the pump core 32 drives the cooling medium through the circulation pipe element 22 into the heat dissipation cavity 17, realizing circulation flow. The compact structure design of this embodiment, the reasonable layout and tight connection of the motor assembly 1, the cooling circulation assembly 2, and the water pump assembly 3, realizes efficient use of space. The orderly arrangement of various components such as the stator support 11 and the rotor support 13 in the motor assembly 1 provides a stable and reasonable structural foundation for the realization of cooling circulation while ensuring the normal operation of the motor. The design of the connecting cavity 16 and the heat dissipation cavity 17 on the stator bracket 11 not only meets the installation requirements of the output connecting shaft 15, but also creates dedicated space for heat dissipation of the stator element 12, making the internal structure of the motor compact and functionally clear. Regarding cooling effect, the cooling circulation assembly 2 and the water pump assembly 3 work together. The circulation pipe element 22 effectively connects the pump core 32 to the heat dissipation cavity 17. Driven by the motor assembly 1, the pump core 32 can stably and efficiently drive the cooling medium to circulate. After the cooling medium enters the heat dissipation cavity 17, it can promptly remove the heat generated by the stator element 12 during operation, ensuring that the stator element 12 operates in a suitable temperature environment, thereby effectively improving the motor's working efficiency and stability, and extending the motor's service life. The reduction of additional connection structures and components lowers the system's complexity and the probability of failure. Direct connections between components reduce the risk of leakage and improve the reliability of the entire cooling system. At the same time, the reduced connection structures also lower the system's energy consumption and improve energy utilization efficiency. This utility model, through its unique structural design and working principle, demonstrates outstanding technical advantages in multiple aspects such as compactness, cooling effect, reliability, and energy consumption, providing a strong guarantee for the efficient operation of motor equipment.

[0028] The connecting cavity 16 has recesses 161 at both ends, and rotary bearings 162 are installed within the recesses 161. The output connecting shaft 15 is mounted on the rotary bearings 162, and a coupling 151 is installed at one end of the output connecting shaft 15, connecting it to the pump core 32. In this embodiment, the recesses 161 and rotary bearings 162 provide a stable and precise support structure for the output connecting shaft 15. This ensures the smoothness of the output connecting shaft 15 during high-speed rotation, greatly reducing vibration and noise during operation, and improving the operational stability and reliability of the entire cooling mechanism. The use of coupling 151 enables efficient power transmission between the output connecting shaft 15 and the pump core 32. It effectively compensates for the relative displacement between the two shafts, ensuring accurate power transmission while also buffering and damping vibrations, reducing damage to components caused by impacts during the operation of the motor and pump, and extending the service life of the equipment.

[0029] A connecting panel 111 is provided on one side of the stator support 11. The connecting panel 111 has a liquid connection hole 112, which connects the heat dissipation cavity 17 to the circulation pipe element 22. A sealing groove 113 is provided on the outer periphery of the liquid connection hole 112 on the connecting panel 111. A sealing ring is provided on the sealing groove 113, which abuts against the circulation pipe element 22. In this embodiment, the liquid connection hole 112 connects the heat dissipation cavity 17 to the circulation pipe element 22, establishing an efficient coolant circulation path. This allows the heat generated by the motor operation to be transferred to the circulation pipe in a timely manner through the heat dissipation cavity 17 and carried away by the coolant circulation, effectively reducing the motor temperature, ensuring stable and efficient operation, and extending the motor's service life. The design of the sealing groove 113 and the sealing ring ensures a tight fit against the circulation pipe element 22 under the positioning effect of the sealing groove 113, forming a reliable sealing structure. It prevents coolant leakage at the connection points, avoids the problem of reduced cooling efficiency due to coolant loss, and also prevents external impurities and moisture from entering the cooling system, ensuring the cleanliness and stability of the entire cooling mechanism.

[0030] A aligning connector 114 is provided on the connecting panel 111. The aligning connector 114 has an aligning connection hole 115. One end of the aligning connection hole 115 is connected to the liquid inlet hole 112, and the other end is connected to the circulation pipe element 22 for guiding the cooling medium transmission. Specifically, two circulation pipe elements 22 are provided, each connected to one of the two aligning connectors 114, for the entry and exit of the cooling medium in the heat dissipation cavity 17. In this embodiment, the aligning connection hole 115 on the aligning connector 114 precisely realizes the guiding function of the cooling medium transmission. One end is connected to the liquid inlet hole 112, ensuring that the cooling medium can be smoothly introduced from the source, and the other end is connected to the circulation pipe element 22, accurately delivering the medium to the required location, ensuring the accuracy and stability of the cooling medium transmission path. The two circulation pipe elements 22, each connected to one of the two aligning connectors 114, form an efficient cooling medium circulation system for the heat dissipation cavity 17. This allows the cooling medium to flow in and out of the heat dissipation chamber 17 in an orderly manner, effectively exchanging and removing the heat generated by the motor and water pump, thus greatly improving heat dissipation efficiency. Stable medium circulation can maintain the motor and water pump within a suitable operating temperature range, effectively avoiding problems such as performance degradation and accelerated aging of components due to overheating.

[0031] One end of the fixed bracket 21 is connected to the connecting panel 111. The circulating pipe element 22 is equipped with a heat dissipation element 221, which is located on the outside of the fixed bracket 21 for heat dissipation of the circulating pipe element 22. In this embodiment, the robust connection structure ensures the stability of the entire cooling system. The reliable connection between the fixed bracket 21 and the connecting panel 111 allows the circulating pipe element 22 to be installed stably, reducing problems such as pipe loosening and leakage that may be caused by vibration or displacement, and ensuring the continuous and stable operation of the cooling cycle. Secondly, the external design of the heat dissipation element 221 greatly improves the heat dissipation efficiency. The heat generated by the circulating pipe element 22 during operation can be quickly dissipated to the surrounding environment through the heat dissipation element 221, preventing heat accumulation in the pipe, effectively reducing the temperature of the circulating liquid, thereby improving the cooling effect of the integrated motor and water pump equipment, ensuring that the equipment operates efficiently in a suitable temperature environment, and extending the service life of the equipment.

[0032] The pump bracket 31 has circulation connectors 311 on both sides, which connect the circulation pipe element 22 to the pump core 32 for cooling medium circulation. In this embodiment, the circulation connectors 311 can accurately and securely connect the circulation pipe element 22 to the pump core 32, creating an efficient path for cooling medium circulation. This ensures that the cooling medium can circulate smoothly and unobstructed throughout the system, effectively removing the large amount of heat generated by the motor and pump during operation and maintaining the equipment within a suitable operating temperature range. Stable circulation not only greatly improves cooling efficiency and ensures the performance stability and reliability of the motor and pump, but also reduces the probability of failures caused by overheating and extends the service life of the equipment.

[0033] The stator element 12 includes a stator frame 121 and a stator winding 122. Multiple winding arms are provided on the stator frame 121, and the stator winding 122 is wound around the winding arms. The rotor element 14 includes multiple rotor magnets 141, which are mounted on the rotor support 13 and opposite to the winding arms. In this embodiment, the multiple winding arms on the stator frame 121 provide a stable and reliable winding foundation for the stator winding 122, ensuring the regularity and stability of the stator winding 122 layout. This is beneficial for improving electromagnetic conversion efficiency and reducing electrical losses and fault risks that may be caused by winding swaying or displacement. The rotor magnets 141 are mounted on the rotor support 13 and opposite to the winding arms, forming a highly efficient magnetic circuit structure. This relative layout can precisely realize the interaction of magnetic fields, enabling the motor to generate a stable and strong rotating magnetic field, driving the rotor to rotate smoothly, and thus driving the water pump impeller to operate efficiently. This reduces magnetic field leakage and energy loss, improves the energy utilization efficiency of the integrated motor-pump cooling mechanism, and enhances the stability and reliability of system operation.

[0034] An output connection end 152 is provided at the end of the output connecting shaft 15 that is away from the coupling 151. The output connection end 152 is used to connect to the output end of the motor and extends to the outside of the stator bracket 11. In this embodiment, from a structural layout perspective, this arrangement makes the connection between the motor and the water pump clearer and more reasonable. The externally located output connection end 152 facilitates installation and maintenance operations, allowing staff to more easily inspect and replace parts at the connection points, effectively reducing maintenance difficulty and costs. In terms of power transmission, this direct connection method can reduce energy loss during the energy transmission process, improve power transmission efficiency, and ensure that the power output from the motor can be efficiently and stably transmitted to the water pump, thereby improving the working efficiency of the entire cooling mechanism. In addition, the output connection end 152 extending to the outside of the stator bracket 11 can better adapt to the connection requirements of motors of different specifications, enhancing the versatility and adaptability of the cooling mechanism.

[0035] The pump core 32 includes a fixed part 321, a movable part 322, and a connecting part 323. The connecting part 323 connects the fixed part 321 to the output connecting shaft 15. The movable part 322 is disposed within the fixed part 321 to drive the cooling medium to flow internally. In this embodiment, the fixed part 321 provides a stable support foundation for the entire pump core 32, ensuring its reliable positioning within the complex integrated structure. The connecting part 323 securely connects the fixed part 321 to the output connecting shaft 15, ensuring efficient and stable power transmission, enabling the motor's power to be accurately transmitted to the pump core 32, thereby driving the delivery of the cooling medium. The movable part 322, disposed within the fixed part 321, can flexibly drive the cooling medium to flow internally. This ensures that the cooling medium flows evenly through the heat-generating parts of the motor, achieving efficient and balanced heat dissipation, effectively reducing the heat generated during motor operation, improving the motor's operational stability and reliability, and extending the motor's service life.
