Description
Technical Field
[0001] This utility model relates to the field of feed processing machinery, and in particular to a drive motor for a feed mixing device with a heat dissipation structure. Background Technology
[0002] Feed mixing equipment is one of the key pieces of equipment in modern feed industry production. The long-term stable operation of its drive motor has a significant impact on ensuring the continuity of the production line and the stability of product quality. During feed processing, the mixing process usually requires the motor to operate continuously under high load. If the heat generated cannot be dissipated in time, it will cause the motor temperature to rise too high, which will affect its working efficiency, service life, and even cause failure and shutdown.
[0003] Currently, the commonly used air-cooling combined with heat sinks in this field has certain limitations in terms of heat dissipation area and efficiency, making it difficult to meet the heat dissipation requirements under high-intensity production conditions.
[0004] Therefore, it is necessary to design a more efficient and reliable motor cooling solution. Utility Model Content
[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a drive motor for a feed mixing device with a heat dissipation structure. This motor utilizes a liquid circulation cooling system with cooling channels, enabling more efficient and reliable heat dissipation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a drive motor for a feed mixing device with a heat dissipation structure, which is installed in the feed mixing device and includes:
[0008] The motor body, used to drive the feed mixing equipment, is fixed to the outside of the feed mixing equipment by a mounting bracket;
[0009] A heat dissipation assembly is used to dissipate heat from the motor body, and it is fixed to the outside of the feed mixing equipment by the mounting bracket; the heat dissipation assembly includes a housing and a fluid circulation module;
[0010] The housing is fitted onto the outside of the motor body, and a heat-conducting medium layer is filled between the inner wall of the housing and the outer wall of the motor body; a fluid flow channel is formed inside the wall of the housing; and a fluid inlet and a fluid outlet connected to the fluid flow channel are also provided on the housing.
[0011] The fluid circulation module is used to drive the cooling fluid to circulate within the fluid flow channel; the fluid circulation module includes a pump body connected by a pipe, an input pipe connected to the fluid inlet, and an output pipe connected to the fluid outlet;
[0012] in,
[0013] The cooling fluid circulates within the fluid channel, allowing the heat generated by the motor body during operation to be conducted to the outside.
[0014] Furthermore, the fluid channels are distributed in a serpentine pattern within the casing.
[0015] Furthermore, the fluid channels are spirally distributed within the casing.
[0016] Furthermore, the central angle between the fluid inlet and the fluid outlet in the circumferential direction of the casing is not less than 150°.
[0017] Furthermore, the heat dissipation component further includes:
[0018] A secondary heat dissipation module includes a heat-conducting base, a set of heat dissipation fins fixedly installed on the heat-conducting base, and a cooling fan installed on the heat-conducting base and facing the heat dissipation fins;
[0019] At least a portion of the output pipe of the fluid circulation module is thermally fixedly attached to the thermally conductive base;
[0020] in,
[0021] The secondary heat dissipation module provides auxiliary heat dissipation for the cooling fluid flowing through the output pipe.
[0022] Furthermore, the heat dissipation fins are flat, and the surface of the fins forms an angle of not less than 50° with the airflow direction of the cooling fan.
[0023] Furthermore, the heat dissipation fins are provided with multiple ventilation holes.
[0024] Furthermore, the diameter of the ventilation holes on the plurality of heat dissipation fins gradually decreases in the direction away from the cooling fan.
[0025] This utility model has at least the following advantages or beneficial effects:
[0026] This invention employs a casing structure fitted onto the outside of the motor body, with a heat-conducting medium layer filled between the inner wall of the casing and the outer wall of the motor. This structure facilitates heat transfer from the motor to the casing. It also incorporates a fluid flow channel formed inside the casing wall and a fluid circulation module connected to it. This structure allows for the continuous removal of heat through circulating cooling fluid. Overall, this invention improves the heat dissipation efficiency of the motor during operation through active fluid circulation cooling.
[0027] This invention employs a secondary heat dissipation module comprising a heat-conducting base, heat dissipation fins, and a cooling fan. The output pipe of the fluid circulation module is thermally fixedly attached to the heat-conducting base. This structure allows for further cooling of the cooling fluid that has already absorbed heat. The combination of the heat dissipation fins and the cooling fan increases the contact area with air and forces convection. Overall, this invention accelerates the cooling of the circulating cooling fluid, ensuring it returns to the pump body at a lower initial temperature, thereby maintaining the heat dissipation capacity of the circulation system.
[0028] This invention employs heat dissipation fins with ventilation holes that gradually decrease in diameter away from the cooling fan. This structure allows for adjustment of airflow distribution as air passes over the fins at different positions. Overall, this invention compensates for the reduced heat dissipation capacity at the rear end caused by airflow deceleration or heating along the path, resulting in a more uniform heat dissipation effect across the entire heat dissipation fin array.

[0044] This utility model embodiment discloses a drive motor for a feed mixing device with a heat dissipation structure.
[0045] Figure 1 A schematic diagram of the installation of the drive motor for a feed mixing device with a heat dissipation structure;
[0046] In this embodiment, a drive motor for a feed mixing device with a heat dissipation structure is installed on the feed mixing device, and includes a motor body 1 and a heat dissipation component 2.
[0047] The motor body 1 provides power to drive the mixing mechanism of the feed mixing equipment. It is fixed to the outside of the feed mixing equipment via a mounting bracket to isolate vibration and facilitate maintenance. In this embodiment, the motor body 1 is a standard three-phase asynchronous motor; in other embodiments, the motor body 1 can also be a permanent magnet synchronous motor or a DC motor to adapt to different power supply conditions and control requirements. The mounting bracket is made of carbon steel through cutting and welding processes, with a thickness of 5 mm to 10 mm, preferably 8 mm; in other embodiments, the mounting bracket can also be assembled from aluminum alloy profiles using bolt connections to reduce weight.
[0048] The function of the heat dissipation component 2 is to effectively dissipate the heat generated by the motor body 1 during operation. It is also fixed to the outside of the feed mixing equipment by the mounting bracket to ensure a stable relative position with the motor body 1.
[0049] Figure 2 This is a schematic diagram of the heat dissipation component; Figure 3 for Figure 2 Front view of the heat dissipation component.
[0050] The heat dissipation component 2 includes a housing 21 and a fluid circulation module 22.
[0051] Figure 4 This is a schematic diagram of the casing.
[0052] The housing 21 is fitted onto the outside of the motor body 1. A thermally conductive medium layer is filled between the inner wall of the housing 21 and the outer wall of the motor body 1. This thermally conductive medium layer reduces thermal resistance and enhances the efficiency of heat conduction from the motor body 1 to the housing 21. In this embodiment, the thermally conductive medium layer is thermally conductive silicone grease; in other embodiments, the thermally conductive medium layer can also be a phase change material or a thermally conductive pad to adapt to different temperature ranges and installation conditions.
[0053] In this embodiment, the casing 21 is made by aluminum alloy casting and has a wall thickness of 8 mm to 15 mm, preferably 12 mm, to balance thermal conductivity and structural strength. In other embodiments, the casing 21 can also be made of copper alloy by machining to improve thermal conductivity.
[0054] The casing 21 has a fluid flow channel 211 inside its wall. The function of the fluid flow channel 211 is to allow cooling fluid to flow and carry away heat. The casing 21 also has a fluid inlet 212 and a fluid outlet 213 connected to the fluid flow channel 211. The function of the fluid inlet 212 and the fluid outlet 213 is to guide the cooling fluid into and out of the fluid flow channel 211, respectively.
[0055] In this embodiment, the fluid flow channel 211 is distributed in a serpentine pattern within the housing 21. This distribution can increase the flow path length of the cooling fluid within the housing 21. The cross-section of the fluid flow channel 211 is circular, with a diameter of 6 mm to 12 mm, preferably 8 mm.
[0056] In other embodiments, the fluid channels 211 may also be spirally distributed within the housing 21 to achieve more uniform axial heat exchange. The pitch of the spiral distribution is 20 mm to 40 mm, preferably 30 mm.
[0057] The central angle between the fluid inlet 212 and the fluid outlet 213 on the circumference of the housing 21 is not less than 150°. This arrangement allows the inflowing and outflowing cooling fluids to maintain a sufficient spatial distance. In this embodiment, the central angle is 180°. In other embodiments, the central angle may be 160° or greater to further reduce thermal short circuits.
[0058] The fluid circulation module 22 is used to drive the cooling fluid to circulate within the fluid flow channel 211. It includes a pump body 223 connected by a pipe, an input pipe 221 connected to the fluid inlet 212, and an output pipe 222 connected to the fluid outlet 213.
[0059] The function of pump body 223 is to provide power to drive the circulation of cooling fluid. The function of inlet pipe 221 and outlet pipe 222 is to connect pump body 223 to fluid inlet 212 and fluid outlet 213, respectively.
[0060] In this embodiment, the pump body 223 is a centrifugal pump; in other embodiments, the pump body 223 may also be a gear pump or a plunger pump to adapt to different flow and pressure requirements.
[0061] The inlet pipe 221 and outlet pipe 222 are made of rubber or PVC material through an extrusion process, and have an inner diameter of 10 mm to 20 mm, preferably 15 mm; the pipe connections are secured with clamps to ensure a tight seal. In other embodiments, the pipe connections may also be made using quick couplings or welding.
[0062] The cooling fluid is a mixture of water and ethylene glycol; in other embodiments, the cooling fluid may also be mineral oil or synthetic heat transfer oil to provide a wider operating temperature range.
[0063] The heat dissipation component 2 further includes a secondary heat dissipation module 23.
[0064] Figure 5 This is a schematic diagram of the secondary heat dissipation module; Figure 6 This is a schematic diagram of heat dissipation fins.
[0065] The secondary heat dissipation module 23 is used to assist in cooling the cooling fluid flowing through the output pipe 222. It includes a heat-conducting base 231, a set of heat dissipation fins 232 fixedly installed on the heat-conducting base 231, and a cooling fan 233 installed on the heat-conducting base 231 and facing the heat dissipation fins 232.
[0066] At least a portion of the output pipe 222 of the fluid circulation module 22 is thermally fixedly attached to the thermally conductive base 231. This attachment method facilitates the transfer of heat from the output pipe 222 to the thermally conductive base 231. In this embodiment, the thermally conductive base 231 is made of copper plate by milling, and its thickness is 5 mm to 15 mm, preferably 10 mm, to provide high thermal conductivity. In other embodiments, the thermally conductive base 231 can also be made of aluminum profile by extrusion to reduce costs.
[0067] The heat dissipation fins 232 are flat, and their surface forms an angle of not less than 50° with the airflow direction of the cooling fan 233. This angle can change the airflow field flowing over the surface of the fins. In this embodiment, the angle is 90°. In other embodiments, the angle can also be 70° or 80° to optimize airflow and heat dissipation.
[0068] The heat dissipation fins 232 are made by stamping aluminum material and have a thickness of 0.5 mm to 1.5 mm, preferably 1.0 mm. The spacing between the heat dissipation fins 232 is 5 mm to 15 mm, preferably 10 mm, to balance the heat dissipation area and airflow resistance.
[0069] Multiple ventilation holes 234 are provided on the heat dissipation fins 232. The function of the ventilation holes 234 is to increase the heat dissipation surface area and promote air penetration while ensuring structural strength. The diameter of the ventilation holes 234 on the multiple heat dissipation fins 232 gradually decreases in the direction away from the cooling fan 233. This change in diameter can adjust the airflow distribution when the air flows through the fins at different positions.
[0070] In this embodiment, the diameter of the ventilation hole 234 gradually decreases from 10.0 mm near the cooling fan 233 to 2.0 mm away from the fan; in other embodiments, the diameter of the ventilation hole 234 may also be reduced from 15 mm to 5 mm to accommodate different airflow conditions.
[0071] The function of the cooling fan 233 is to force airflow over the heat dissipation fins 232 to enhance convective heat transfer; in this embodiment, the cooling fan 233 is an axial fan; in other embodiments, the cooling fan 233 may also be a centrifugal fan to adapt to different space and air pressure requirements.
[0072] The fixed installation method uses riveting or bolting to ensure structural stability; in other embodiments, welding or bonding methods may also be used.
[0073] Overall, this invention combines a motor body 1 with a heat dissipation component 2. The heat dissipation component 2 includes a housing 21, a fluid circulation module 22, and a secondary heat dissipation module 23. The housing 21 is in close contact with the motor body 1 through a thermally conductive medium layer, which can reduce thermal resistance and promote heat transfer. The fluid circulation module 22 drives cooling fluid to circulate within the fluid channel 211 via a pump 223, which can continuously remove heat. The secondary heat dissipation module 23 provides auxiliary cooling to the output pipe 222 through a thermally conductive base 231, heat dissipation fins 232, and a cooling fan 233, which can further improve heat dissipation efficiency. In summary, the combination of these structures can, to a certain extent, improve the motor's heat dissipation efficiency through active fluid circulation and secondary heat dissipation, reduce performance degradation caused by overheating, and have a positive effect on extending the motor's service life and maintaining the continuous operation of the feed mixing equipment.
[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
