Description

Technical Field

[0001] This utility model relates to the field of heater technology, and more specifically, to a magnet-moving high-temperature superconducting DC induction heating device. Background Technology

[0002] Traditional electromagnetic induction heating technology has been widely used in the steel processing industry due to its simple structure and environmental friendliness. However, when heating non-ferromagnetic materials such as aluminum or copper, the energy efficiency of the heater is greatly reduced. Superconducting DC induction heaters are devices that utilize eddy currents generated in a DC magnetic field by superconducting materials for heating. Superconducting DC induction heating is an organic combination of superconducting power application technology and induction heating technology, fully utilizing the low-loss characteristics of superconductivity in a DC environment. Combined with electromagnetic induction technology, it enables preheating before aluminum extrusion in the aluminum processing industry. Currently, during the production of aluminum alloy profiles, the aluminum material needs to be heated to a suitable temperature (usually between 400℃ and 500℃) using a superconducting DC induction heater to facilitate extrusion. The purpose of heating is to soften the aluminum material, making it easier to form in the extruder.

[0003] In the current technology of superconducting DC induction heaters, when processing aluminum alloy profiles, the heat treatment of the aluminum alloy profiles results in a large amount of heat around the superconducting DC induction heater. The current technology of superconducting DC induction heaters mainly focuses on reducing their own energy consumption, that is, making full use of the low loss characteristics of superconductivity in DC environment. However, superconducting DC induction heaters still have certain deficiencies in waste heat recovery, because the heat energy of heat treatment is easily lost, resulting in resource waste and being detrimental to energy conservation and environmental protection.

[0019] In a preferred embodiment, the outer shell is fixedly connected to the outside of the heat insulation cover, and a partition plate is fixedly connected inside the outer shell.

The outer shell is divided into two cooling chambers by the partition plate, and the cooling chambers are provided with coolant for immersing the cold source substrate.

[0020] In a preferred embodiment, a ventilation and heat dissipation assembly is provided on multiple heat conduction pipes. The ventilation and heat dissipation assembly includes an air collection pipe, with multiple heat conduction pipes fixedly connected to the air collection pipe.

[0021] In a preferred embodiment, each heat pipe is provided with a metal filter screen at the end facing away from the air duct.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] 1. In this magnet-mobile high-temperature superconducting DC induction heating device, when the aluminum alloy profile is softened by the superconducting heating unit, the residual heat generated by the heating of the aluminum alloy profile can be retained in the heat insulation cover. By placing the heat source substrate inside the heat insulation cover and the cold source substrate outside the heat insulation cover, the temperature difference between the two allows the charge carriers to move towards the cold source substrate through the thermoelectric material. The concentrated residual heat is recovered and converted into electricity by the thermoelectric conversion unit, which can reduce the loss of heating heat energy of the superconducting heating unit and improve resource utilization.

[0024] 2. This magnet-mobile high-temperature superconducting DC induction heating device utilizes heat conduction through the setting of waste heat conduction components and an induced draft fan. It takes advantage of the excellent thermal conductivity of the heat conduction plates and fins, and utilizes the heat conduction channels set between the baffles and the fins. The function of the induced draft fan is to accelerate the absorption of waste heat in the insulation cover through the heat conduction channels by the fins. The absorbed heat can be transferred to the heat source substrate to form a high heat source end, thereby increasing the temperature of the heat source substrate. This provides a thermal excitation effect, thereby improving the efficiency of heat energy to electrical energy conversion.

[0025] 3. This magnet-movable high-temperature superconducting DC induction heating device lowers the temperature of the cold source substrate by immersing it in the coolant, thereby increasing the temperature difference between the heat source substrate and the cold source substrate. This promotes carrier migration. Furthermore, due to the heat pipe passing through the cooling cavity, the ventilation and heat dissipation components are designed to introduce ventilation into the lower part of the heat pipe channel. This allows the induced draft fan to accelerate the airflow within the heat pipe. By utilizing the heat absorption characteristics of the heat pipe on the coolant, the heat absorption temperature of the coolant can be effectively controlled, ensuring the stability of the cold source substrate's operation.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] See also Figures 1-7 This utility model provides a magnet-movable high-temperature superconducting DC induction heating device, including a base 1, a superconducting heating unit, a heat insulation cover 2, a thermoelectric conversion unit 4, a waste heat conduction component 5, an induced draft fan 6, and a shell 7.

[0036] The base 1 serves as the support for the bottom of the superconducting DC induction heater used for extruding the entire alloy profile.

[0037] In this embodiment: the superconducting heating unit is mounted on the base 1. The superconducting heating unit is used to heat the aluminum alloy profile to be extruded (hereinafter referred to as aluminum material). By softening the aluminum material, it can be shaped by subsequent extrusion using an existing extrusion press. The superconducting heating unit includes a pair of magnetic cores 3, both of which are movably connected to the upper surface of the base 1. Each magnetic core 3 is provided with a superconducting coil 31. An air gap is formed between the pair of magnetic cores 3 for rotating heating of the aluminum alloy profile. Of course, the magnetic cores 3 can also be fixedly connected to the base 1. In this solution, the superconducting heating unit can also be other conventional designs in the art, such as a high-temperature superconducting induction heating device for heat treatment of large cylindrical sections disclosed in Chinese Patent Publication No. CN108374074A, or a superconducting magnet based on a racetrack-shaped superconducting ring disclosed in Chinese Patent Publication No. CN110211764A.

[0038] In use, by supplying DC power in opposite directions to the two superconducting coils 31, the magnetomotive force formed by the two superconducting coils 31 forms a series mode, generating a magnetic field between a pair of magnetic cores 3. By moving the aluminum material into the air gap and controlling the rotation of the aluminum material, the aluminum material rotates and cuts the magnetic field in the air gap, generating eddy currents to achieve the effect of induction heating. By adjusting the rotation speed of the aluminum material, the cutting speed of the magnetic field can be changed, thereby controlling the heating efficiency. How to control the rotation of the aluminum material in this application is a mature existing technology, so it will not be elaborated on here.

[0039] In this embodiment: the heat insulation cover 2 is set on the outside of the superconducting heating unit, the heat insulation cover 2 is provided with a heat insulation layer on the inside, the heat insulation cover 2 is fixedly connected to the upper surface of the base 1, and side plates 11 are fixedly connected to both ends of the heat insulation cover 2. Each side plate 11 is provided with a processing port 12 for aluminum alloy profiles to pass through.

[0040] The insulation layer can be made of fire-resistant insulation cotton, which can delay the loss of internal residual heat in the insulation cover 2. The processing opening 12 on the side plate 11 can meet the requirement of aluminum material entering the air gap. In this application, the inner side of the side plate 11 may be provided with an insulation layer to meet the overall insulation performance of the insulation cover 2.

[0041] In this embodiment: The thermoelectric conversion unit 4 is disposed through the heat insulation cover 2. The thermoelectric conversion unit 4 includes a heat source substrate 41, which is fixedly connected to the inner wall of the heat insulation cover 2. A P-type semiconductor 42 and an N-type semiconductor 43 are fixedly connected to one side of the heat source substrate 41, and one end of each of the P-type semiconductor 42 and the N-type semiconductor 43 passes through the heat insulation cover 2 and is fixedly connected to a cold source substrate 44.

[0042] The heat source substrate 41 is made of graphene, and the cold source substrate 44 is made of aluminum. Both the P-type semiconductor 42 and the N-type semiconductor 43 are thermochromic materials. By placing the heat source substrate 41 inside the heat insulation cover 2, when the aluminum material is heat-treated by the superconducting heating unit, the heat source of the aluminum material itself can be radiated into the heat insulation cover 2. At this time, the heat source substrate 41 can be heated to a high temperature by the radiated heat source, while the cold source substrate 44 is placed on the outside of the heat insulation cover 2 as a low temperature end. In this way, the charge carriers at the heat source substrate 41 can be greater than those at the cold source substrate 44. When the charge carriers on the heat source substrate 41 migrate to the cold source substrate 44, a potential difference can be generated. By electrically connecting a pair of cold source substrates 44 to an existing battery, the battery can store the electrical energy generated on the cold source substrates 44 to meet the power needs of the existing instruments mounted on the magnet-movable high-temperature superconducting DC induction heating device.

[0043] In this embodiment: the waste heat conduction component 5 is located inside the heat insulation cover 2, and the waste heat conduction component 5 is disposed on the thermoelectric conversion unit 4. The waste heat conduction component 5 includes multiple heat conduction fins 53, and the multiple heat conduction fins 53 are fixedly connected to the other side of the heat source substrate 41.

[0044] Multiple heat-conducting fins 53 can absorb the heat radiated inside the heat insulation cover 2, so as to evenly transfer the absorbed heat waves to the heat source substrate 41, thus making the heat source substrate 41 a stable high-temperature end.

[0045] It is worth noting that during the heating process of the aluminum material through the superconducting heating unit, the heat transfer is mainly provided by the heat-conducting fins 53 to the heat source substrate 41, and the graphene material of the heat source substrate 41 also has certain heat absorption characteristics.

[0046] In this embodiment, the waste heat conduction component 5 also includes a heat conduction plate 51, which is fixedly connected to the heat source substrate 41. Multiple baffles 52 are fixedly connected to the inner side of the heat conduction plate 51, and heat conduction fins 53 are located on one side of the baffles 52. The multiple baffles 52 and the multiple heat conduction fins 53 are staggered, and heat conduction channels are reserved between the multiple baffles 52 and the multiple heat conduction fins 53.

[0047] The heat-conducting plate 51 is made of copper and has a U-shaped structure. This allows the heat-conducting plate 51 to surround the periphery of the heat source substrate 41, and the top and bottom of the heat-conducting plate 51 and the heat source substrate 41 are open to facilitate air circulation. The baffle plate 52 can work with the heat-conducting fins 53 to form an S-shaped heat-conducting channel. Under the action of the external air-exhaust equipment, the residual heat in the heat insulation cover 2 can pass through the heat-conducting channel more quickly, which can improve the efficiency of the heat-conducting fins 53 in absorbing residual heat.

[0048] In this embodiment, the heat-conducting plate 51 has multiple ventilation micro-holes 13.

[0049] When the heat conduction channel is used for ventilation, the ventilation volume of the multiple ventilation micro-holes 13 is less than that of the heat conduction channel. This ensures that the ventilation efficiency of the heat conduction channel from bottom to top is stable while guaranteeing the amount of residual heat entering the insulation cover 2 through the heat conduction channel.

[0050] In this embodiment: the exhaust fan 6 is set on the top of the heat insulation cover 2, and the exhaust fan 6 is located at the top of the waste heat conduction component 5. The top of the heat conduction plate 51 is fixedly connected to the hood 14, and one end of the hood 14 passes through the heat insulation cover 2 and is connected to the exhaust end of the exhaust fan 6.

[0051] By activating the induced draft fan 6, the shroud 14 can concentrate the airflow into the heat conduction channel. The airflow can accelerate the movement of residual heat in the heat conduction channel within the insulation cover 2, thereby improving the efficiency of the heat conduction fins 53 in absorbing residual heat and enhancing the heat transfer effect from the heat conduction fins 53 to the heat source substrate 41.

[0052] It is worth noting that when using the induced draft fan 6 and the heat conduction channel, the aluminum material is in the state of being heated and removed. This avoids the problem of unstable heating of the aluminum material due to the influence of the induced draft fan 6 when it is heated by the superconducting heating unit.

[0053] In this embodiment: the outer shell 7 is disposed on the outside of the heat insulation cover 2, and a cooling cavity 8 connected to the thermoelectric conversion unit 4 is disposed inside the outer shell 7. The cooling cavity 8 is used to cool the thermoelectric conversion unit 4. The outer shell 7 is fixedly connected to the outside of the heat insulation cover 2. A partition plate 15 is fixedly connected inside the outer shell 7. One end of the P-type semiconductor 42 and the N-type semiconductor 43 both pass through the partition plate 15. The outer shell 7 is divided into two cooling cavities 8 by the partition plate 15, and a coolant for immersing the cold source substrate 44 is disposed inside the cooling cavity 8.

[0054] The housing 7 is divided into two cooling chambers 8 by the partition plate 15. The P-type semiconductor 42 and the N-type semiconductor 43 are sealed through the partition plate 15, so that the two cold source substrates 44 can be cooled independently by the coolant, so that the cold source substrates 44 are at a low temperature and at the same time, it prevents short circuits when the cold source substrates 44 are connected to the battery wire.

[0055] In this embodiment, multiple heat pipes 9 are sequentially passed through the outer shell 7 and the cooling cavity 8.

[0056] The heat pipe 9 is sealed through the outer shell 7 and the cooling cavity 8, so the heat pipe 9 can be vacuum-placed in the coolant. The heat pipe 9 is made of copper with heat absorption capacity. When the cold source substrate 44 generates heat while running in the coolant, the heat pipe 9 can absorb heat from the coolant to transfer the heat, thus stabilizing the low temperature environment of the cold source substrate 44.

[0057] In this embodiment: a ventilation and heat dissipation assembly 10 is jointly provided on multiple heat conduction pipes 9. The ventilation and heat dissipation assembly 10 includes an air collecting pipe 101, with multiple heat conduction pipes 9 fixedly connected to the air collecting pipe 101. Multiple air ducts 102 are fixedly connected to the air collecting pipe 101, and one end of each air duct 102 passes through the insulation cover 2 and is fixedly connected to an air outlet pipe 103. The air outlet pipe 103 is spiral-shaped, and the end of the air outlet pipe 103 facing away from the air duct 102 is located below the heat conduction channel. In this solution, the ventilation and heat dissipation assembly can also be other conventional designs, such as the duct heat dissipation type computer room ventilation system and its control method disclosed in Chinese Patent Publication No. CN102307446A, or the radiant heat sink with built-in heat conduction pipe disclosed in Chinese Patent Publication No. CN211123961U.

[0058] The exhaust duct 102 is made of ceramic, which reduces the thermal conductivity of residual heat inside the insulation cover 2. The exhaust duct 103 is made of copper, which increases thermal conductivity. When the exhaust fan 6 is used to ventilate the heat conduction channel, the end of the exhaust duct 103 is located below the heat conduction channel, allowing residual heat from the insulation cover 2 to enter through the lower part of the heat conduction channel. Furthermore, in this application, the heat conduction pipe 9, the collecting duct 101, and the exhaust duct 103 are sequentially connected, allowing one end of the heat conduction pipe 9 to introduce outdoor air, which then passes through the collecting duct 101 and the exhaust duct 103 in sequence. The air duct 101 and the air outlet duct 103 enter the lower part of the heat conduction channel. By accelerating the air circulation in the heat conduction pipe 9, the temperature of the coolant absorbed by the heat conduction pipe 9 can be quickly removed, ensuring the stability of the coolant cooling temperature. Furthermore, the spiral arrangement of the air outlet duct 103 can increase the heat absorption area of ​​the residual heat in the insulation cover 2. Thus, when the air outlet duct 103 delivers air below the heat conduction channel, it can absorb the heat of the residual heat in the insulation cover 2 and transfer the heat to the heat conduction fins 53 in the heat conduction channel. This can improve the thoroughness of the recovery of residual heat from the aluminum material in the insulation cover 2.

[0059] In this embodiment, a metal filter 91 is provided at one end of each heat pipe 9 facing away from the air duct 102.

[0060] The metal filter 91 is designed to intercept foreign objects, thus preventing blockages in the air duct 102 caused by foreign objects.

[0061] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
