Description

Technical Field

[0001] This application relates to the technical field of magnet cooling structures, and in particular to a cooling structure for a six-pole magnet. Background Technology

[0002] In industrial production, hexapole magnets, as a type of strong magnetic device with multiple magnetic poles working in tandem, are widely used in magnetic separation equipment, precision instruments, and motor drive systems. Their core working principle is to create a high-intensity, highly stable magnetic field environment through the superposition of the magnetic fields of six sets of magnets, enabling functions such as material separation, energy conversion, or precision adsorption. In high-precision motors, the uniformity of the magnetic field of the hexapole magnets affects the motor's operational stability and energy conversion efficiency. During operation, hexapole magnets continuously generate a significant amount of heat due to hysteresis losses, eddy current effects, and Joule heating of the coils.

[0003] Currently, cooling equipment for hexagonal magnets is mainly divided into two categories: natural heat dissipation and forced cooling. Natural heat dissipation equipment uses metal heat sinks installed on the outside of the magnet to carry away heat through natural air convection. While simple in structure, it has extremely low heat dissipation efficiency and is only suitable for low-power, intermittently operating hexagonal magnets. Forced cooling equipment, on the other hand, uses external force to drive the cooling medium (air or liquid) to exchange heat with the magnet. However, traditional liquid cooling equipment often uses straight or simply bent cooling pipes, with the contact area with the magnet being less than 50% of its surface area, resulting in insufficient heat exchange.

[0004] Meanwhile, traditional equipment lacks real-time temperature monitoring and dynamic adjustment capabilities, and the cooling system operates according to fixed parameters once started. When changes in the load of the six-pole magnet (such as fluctuations in the magnetic separator's processing capacity) cause changes in heat generation, it is impossible to adjust the flow rate or heat dissipation power of the cooling medium in a timely manner. Utility Model Content

[0005] To achieve stable cooling operation, this application provides a cooling structure for a six-pole magnet.

[0006] The cooling structure for a six-pole magnet provided in this application adopts the following technical solution: A cooling structure for a six-pole magnet includes six sets of magnet blocks and a cooling box. A cooling pipe assembly is wound around the outer surface of each set of magnet blocks. A connecting pipe assembly is installed at the outer end of the cooling pipe assembly. A liquid supply pump assembly and a return pipe assembly that cooperate with the connecting pipe assembly are provided on the cooling box. A cooling component is fixedly installed on the top of the cooling box. A circulation pump assembly that cooperates with the cooling component is also fixedly installed on the cooling box.

[0007] By adopting the above technical solution, a complete cooling circulation system is formed by winding cooling pipes around the outer surface of each group of magnets and installing connecting pipes, a cooling tank, a liquid supply pump group, a return pipe group, a cooling component, and a circulation pump group. The liquid supply pump group delivers coolant to the cooling pipe group. After absorbing the heat generated by the magnets, the coolant flows back to the cooling tank through the return pipe group. The cooling component cools the coolant in the cooling tank, and the circulation pump group promotes the circulation of coolant within the cooling component, thereby achieving efficient cooling of the six-pole magnets and ensuring the stable performance and normal operation of the magnets.

[0008] Optionally, the cooling tube assembly includes a spiral tube section, an inlet straight tube, and an outlet straight tube. The spiral tube section is fitted and fixed to the outer surface of the magnet block, and the inlet straight tube and the outlet straight tube are fixedly installed at both ends of the spiral tube section.

[0009] By adopting the above technical solution, the spiral tube section of the cooling tube assembly is fitted and fixed to the outer side of the magnet block, increasing the contact area between the coolant and the magnet block and improving the heat exchange efficiency. The straight inlet and outlet pipes facilitate the inflow and outflow of coolant, ensuring that the coolant can circulate smoothly in the cooling tube assembly, further enhancing the cooling effect.

[0010] Optionally, the connecting pipe assembly includes a riser shell, an inlet bend, and an outlet bend. The outlet bend is located at the lower end of the inlet bend, and both the inlet bend and the outlet bend are fixedly installed on the riser shell. Both ends of the inlet bend and the outlet bend extend from the riser shell.

[0011] By adopting the above technical solution, the riser shell of the connecting pipe assembly serves to protect and support the inlet and outlet bends. The design of the inlet and outlet bends facilitates the connection between the cooling pipe assembly and the supply pump assembly and return pipe assembly, making the coolant delivery smoother. At the same time, the reasonable layout avoids mutual interference between pipes and improves the stability of the entire cooling system.

[0012] Optionally, a temperature sensor is installed on the side of the riser shell, with one end of the temperature sensor extending into the liquid outlet bend, and the temperature sensor is fixedly connected to the riser shell.

[0013] By adopting the above technical solution, a temperature sensor is installed on the side of the riser shell and extends into the outlet bend, enabling real-time monitoring of the temperature of the coolant flowing out of the cooling pipe assembly. By obtaining accurate temperature data, parameters such as the flow rate of the supply pump and the power of the cooling components can be adjusted according to actual conditions, achieving precise control of the cooling process, ensuring cooling effectiveness while avoiding energy waste.

[0014] Optionally, the cooling tank includes a liquid storage tank and a bracket for installing the cooling components. The bracket is installed on the upper surface of the liquid storage tank and is fixedly connected to the liquid storage tank. The upper end of the return pipe assembly is connected to all the liquid outlet bends, and the lower end of the return pipe assembly extends into the liquid storage tank.

[0015] By adopting the above technical solution, the coolant reservoir of the cooling box is used to store coolant, and the bracket provides a stable installation platform for the cooling components. The return pipe assembly returns the coolant, after absorbing heat, to the reservoir, enabling the coolant to be recycled and reducing operating costs. At the same time, this structural design makes the layout of the cooling box reasonable and facilitates maintenance and management.

[0016] Optionally, the cooling component includes a positioning vertical frame, a bent flat tube, and a cooling fan. The bent flat tube is fixedly installed in the positioning vertical frame, and the cooling fan is fixedly installed on the rear end face of the bent flat tube.

[0017] By adopting the above technical solution, the positioning frame of the cooling component provides a fixed support structure for the bent flat tube and the cooling fan. The bent flat tube increases the flow path and heat dissipation area of ​​the coolant, while the cooling fan accelerates airflow, quickly removing the heat dissipated by the bent flat tube, improving the cooling efficiency of the coolant, and ensuring that the coolant in the cooling tank always maintains a low temperature.

[0018] Optionally, a number of corrugated heat dissipation plates are evenly installed from top to bottom in the positioning vertical frame. The corrugated heat dissipation plates are attached to and fixed on the outer side of the bent flat tube, and the two ends of the corrugated heat dissipation plates are fixedly connected to the positioning vertical frame.

[0019] By adopting the above technical solution, the corrugated heat dissipation plate installed in the positioning vertical frame is attached to the outer side of the bent flat tube, further increasing the heat dissipation area. The corrugated structure not only increases the contact area between the air and the heat dissipation plate, but also creates air turbulence, enhancing the heat dissipation effect. The corrugated heat dissipation plate is fixedly connected to the positioning vertical frame, ensuring the stability of the structure.

[0020] Optionally, an outer pipe is fixedly installed on the side of the positioning vertical frame, and several spray pipes are evenly installed on the side of the outer pipe from top to bottom. Several atomizing nozzles are inclined on the side of the spray pipe facing the bent flat pipe.

[0021] By adopting the above technical solution, the external connecting pipe, spray pipe, and atomizing nozzle configuration allows for the spraying of atomized coolant onto the bent flat pipe. The atomized coolant absorbs a large amount of heat during evaporation, further improving the cooling effect of the cooling components. The inclined atomizing nozzles allow the atomized coolant to cover the bent flat pipe more evenly, enhancing the uniformity of cooling.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The cooling structure for the six-pole magnet of this application, through multiple sets of cooling pipes closely attached to the magnet block and the efficient heat dissipation of the cooling components, can quickly and effectively dissipate the heat generated by the magnet block, ensuring that the six-pole magnet operates in a stable temperature environment, thereby improving the magnet's performance and service life. The setting of the temperature sensor enables the cooling system to monitor the temperature of the coolant in real time and adjust relevant parameters according to temperature changes, achieving precise control of the cooling process, avoiding over-cooling or under-cooling, and improving energy utilization efficiency. The cooling components adopt a combination of fan cooling and atomized coolant evaporation cooling, greatly improving heat dissipation efficiency. The use of a wave-shaped heat sink further enhances the heat dissipation effect, ensuring that the coolant can be cooled down quickly, providing a strong guarantee for the continuous cooling of the magnet.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a cooling structure for a six-pole magnet. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, a cooling structure for a six-pole magnet includes six sets of magnet blocks 1 and a cooling box 3. Cooling pipes 10 are wound around the outer surface of each set of magnet blocks 1, and connecting pipes 2 are installed at the outer ends of the cooling pipes 10. A liquid supply pump 31 and a return pipe 32, which cooperate with the connecting pipes 2, are installed on the cooling box 3. A cooling component 4 is fixedly installed directly above the cooling box 3, and a circulation pump 5, which cooperates with the cooling component 4, is also fixedly installed on the cooling box 3. By winding cooling pipes 10 around the outer surface of each set of magnet blocks 1 and providing the connecting pipes 2, cooling box 3, liquid supply pump 31, return pipe 32, cooling component 4, and circulation pump 5, a complete cooling circulation system is formed. The coolant supply pump assembly 31 delivers coolant to the cooling pipe assembly 10. After absorbing the heat generated by the magnet block 1, the coolant flows back to the cooling tank 3 through the return pipe assembly 32. The cooling component 4 cools the coolant in the cooling tank 3, and the circulating pump assembly 5 promotes the circulation of coolant in the cooling component 4, thereby achieving efficient cooling of the six-pole magnet and ensuring stable performance and normal operation of the magnet. The cooling pipe assembly 10 includes a spiral tube section 101, an inlet straight pipe 102, and an outlet straight pipe 103. The spiral tube section 101 is fixedly attached to the outer surface of the magnet block 1, and the inlet straight pipe 102 and the outlet straight pipe 103 are fixedly installed at both ends of the spiral tube section 101. The spiral tube section 101 of the cooling pipe assembly 10 is fixedly attached to the outer surface of the magnet block 1, increasing the contact area between the coolant and the magnet block 1 and improving the heat exchange efficiency. The inlet straight pipe 102 and the outlet straight pipe 103 facilitate the inflow and outflow of coolant, ensuring that the coolant can circulate smoothly in the cooling pipe assembly 10, further improving the cooling effect.

[0032] Reference Figure 2As shown, the connecting pipe assembly 2 includes a riser housing 21, an inlet bend 22, and an outlet bend 23. The outlet bend 23 is located at the lower end of the inlet bend 22, and both the inlet bend 22 and the outlet bend 23 are fixedly installed on the riser housing 21. Both ends of the inlet bend 22 and the outlet bend 23 extend from the riser housing 21. The riser housing 21 of the connecting pipe assembly 2 serves to protect and support the inlet bend 22 and the outlet bend 23. The arrangement of the inlet bend 22 and the outlet bend 23 facilitates the connection between the cooling pipe assembly 10 and the liquid supply pump assembly 31 and the return pipe assembly 32, making the delivery of coolant smoother. At the same time, the reasonable layout avoids mutual interference between pipes and improves the stability of the entire cooling system. A temperature sensor 24 is installed on the side of the riser housing 21. One end of the temperature sensor 24 extends into the outlet bend 23, and the temperature sensor 24 is fixedly connected to the riser housing 21. Temperature sensor 24 is installed on the side of riser housing 21 and extends into outlet bend 23, enabling real-time monitoring of the temperature of the coolant flowing out of cooling pipe assembly 10. By obtaining accurate temperature data, parameters such as the flow rate of supply pump assembly 31 and the power of cooling component 4 can be adjusted according to actual conditions, achieving precise control of the cooling process, ensuring cooling effect while avoiding energy waste.

[0033] Reference Figure 1 and Figure 2 As shown, the cooling tank 3 includes a liquid storage tank 311 and a bracket 312 for mounting the cooling assembly 4. The bracket 312 is mounted on the upper surface of the liquid storage tank 311 and is fixedly connected to the liquid storage tank 311. The upper end of the return pipe assembly 32 is connected to all the liquid outlet bends 23, and the lower end of the return pipe assembly 32 extends into the liquid storage tank 311. The liquid storage tank 311 of the cooling tank 3 is used to store coolant, and the bracket 312 provides a stable mounting platform for the cooling assembly 4. The return pipe assembly 32 returns the coolant, after absorbing heat, to the liquid storage tank 311, enabling the coolant to be recycled and reducing operating costs. At the same time, this structural design makes the layout of the cooling tank 3 reasonable and facilitates maintenance and management.

[0034] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the cooling assembly 4 includes a positioning frame 41, a bent flat tube 42, and a cooling fan 43. The bent flat tube 42 is fixedly installed in the positioning frame 41, and the cooling fan 43 is fixedly installed on the rear end face of the bent flat tube 42. The positioning frame 41 of the cooling assembly 4 provides a fixed support structure for the bent flat tube 42 and the cooling fan 43. The bent flat tube 42 increases the flow path and heat dissipation area of ​​the coolant, and the cooling fan 43 accelerates the airflow, which can quickly remove the heat dissipated by the bent flat tube 42, improve the cooling efficiency of the coolant, and ensure that the coolant in the cooling tank 3 always maintains a low temperature. Several corrugated heat dissipation plates 411 are evenly installed from top to bottom in the positioning frame 41. The corrugated heat dissipation plates 411 are attached to and fixed on the outer surface of the bent flat tube 42, and both ends of the corrugated heat dissipation plates 411 are fixedly connected to the positioning frame 41. The corrugated heat dissipation plates 411 installed in the positioning frame 41 are attached to the outer surface of the bent flat tube 42, further increasing the heat dissipation area. The wavy structure not only increases the contact area between the air and the heat sink, but also creates turbulence, enhancing the heat dissipation effect. The wavy heat sink 411 is fixedly connected to the positioning frame 41, ensuring the stability of the structure. An external pipe 44 is fixedly installed on the side of the positioning frame 41. Several spray pipes 441 are evenly installed on the side of the external pipe 44 from top to bottom. Several atomizing nozzles 442 are inclined towards the side of the spray pipes 441 facing the bent flat tube 42. The arrangement of the external pipe 44, spray pipes 441, and atomizing nozzles 442 allows atomized coolant to be sprayed onto the bent flat tube 42. The atomized coolant absorbs a large amount of heat during evaporation, further improving the cooling effect of the cooling component 4. The inclined atomizing nozzles 442 allow the atomized coolant to cover the bent flat tube 42 more evenly, enhancing the uniformity of cooling.

[0035] The implementation principle of a cooling structure for a six-pole magnet according to an embodiment of this application is as follows: During actual use, the cooling system is activated, and an appropriate amount of coolant is injected into the reservoir 311. The supply pump group 31, the circulation pump group 5, and the cooling fan 43 are started. The supply pump group 31 delivers the coolant to the cooling pipe group 10. After absorbing the heat generated by the magnet block 1, the coolant flows back to the reservoir 311 through the return pipe group 32. The circulation pump group 5 delivers the coolant from the reservoir 311 to the cooling component 4. The cooling fan 43 and the atomizing nozzle 442 cool the coolant. The cooled coolant then flows back to the reservoir 311, forming a complete cooling cycle. The temperature sensor 24 monitors the temperature of the coolant in the outlet bend 23 in real time and transmits the temperature data to the control system. The control system adjusts parameters such as the flow rate of the supply pump group 31, the power of the circulation pump group 5, and the speed of the cooling fan 43 based on the temperature data to achieve precise control of the cooling process.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
