[0037] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.
[0038] The terms "first", "second", and the like in the description and in the claims of the present application are used for distinguishing between similar objects discussed in the specification and claims and are not necessarily used to describe a particular sequential or chronological order. It is to be understood that the use of the terms so
[0039] Some embodiments of the present application disclose an inductive heating device for rapidly heating a blackbody source, comprising a first furnace body 100, a second furnace body 200, a coil 210 and a metal piece 220.
[0040] As shown in Figure 1 and Figure 4 , the first furnace body 100 is used for placing the blackbody source. The first furnace body 100 has a heating function to heat the blackbody source placed therein. In the present embodiment, the first furnace body 100 heats the blackbody source to 1200℃ or above.
[0041] As shown in Figure 2 and Figure 3 , the second furnace body 200 has a channel 230 penetrating along the axial direction thereof for passing fluid. The two ends of the channel 230 are respectively an inlet end and an outlet end, the fluid enters the channel 230 from the inlet end and is heated in the channel 230 to reach a preset temperature, and the fluid is discharged through the outlet end.
[0042] It should be noted that the fluid can be a liquid or a fluid, and the present embodiment is preferably a fluid.
[0043] As shown in Figure 1 , the outlet end of the channel 230 is connected with the first furnace body 100. The fluid heated in the channel 230 to the preset temperature enters the first furnace body 100 to heat the blackbody source placed in the first furnace body 100 to 1200℃ or above.
[0044] As shown in Figure 3As shown, a coil 210 is installed inside the second furnace body 200. The coil 210 is used to connect to an AC power supply, and the metal part 220 is located inside the coil 210. When AC power is applied to the coil 210, the direction and magnitude of the current change periodically, causing an alternating magnetic field to be generated around the coil 210. The alternating magnetic field generated by the coil 210 induces eddy currents inside the metal part 220. The eddy currents rapidly heat the metal part 220 to 1200°C or higher. The metal part 220 then exchanges heat with the fluid in the channel 230 to heat the fluid to 1200°C or higher. Compared with the resistance wire heating method used in the prior art, this embodiment uses eddy current heating of the metal part 220, which is more efficient, thereby increasing work efficiency and reducing testing and time costs.
[0045] like Figure 3 As shown, a filler 240 is provided within the channel 230, surrounding the metal component 220 and having gaps for fluid passage. During eddy current heating, the metal component 220 conducts heat to the filler 240, causing the filler 240 to heat up simultaneously. The filler 240 increases the contact area with the fluid, thus heating the fluid more effectively. Furthermore, the gaps in the filler 240 slow down the fluid flow rate within the channel 230, allowing the fluid to flow within the channel 230 for a longer period, resulting in better heating.
[0046] In some embodiments, the filler 240 is a plurality of ceramic particles. Gaps exist between the ceramic particles, allowing fluid to pass through.
[0047] In some embodiments, the filler 240 is a honeycomb ceramic, the honeycomb structure of which provides gaps for fluid to pass through.
[0048] like Figure 4 As shown, a jacket 110 is provided between the inner and outer walls of the first furnace body 100; the outlet end of the channel 230 is connected to the jacket 110 to allow fluid to enter the jacket 110. The jacket 110 serves as a circulation channel 230 for the fluid, and by directly contacting the inner wall, it uniformly transfers heat to the blackbody source, avoiding local overheating, while the outer wall isolates heat dissipation and reduces energy loss.
[0049] like Figure 4As shown, the second furnace body 200 further comprises a heat exchange part 120 located in the second furnace body 200 and provided with a heat exchange channel 121 for fluid to pass through; one end of the heat exchange channel 121 is in communication with the channel 230 so that the fluid enters the heat exchange channel 121. Part of the fluid flowing out of the channel 230 also enters the heat exchange channel 121 and uniformly transfers heat to the black body source. Moreover, the heat exchange part 120 is located in the second furnace body 200, the fluid in the interlayer 110 exchanges heat from outside to inside, and the fluid in the heat exchange channel 121 exchanges heat from inside to outside, eliminating the temperature difference between inside and outside, so that the black body source is heated more uniformly.
[0050] As shown in Figure 1 and Figure 4 , the first furnace body 100 is provided with a first outlet in communication with the interlayer 110 and a second outlet in communication with the heat exchange channel 121, and the second furnace body 200 is provided with a backflow port in communication with the channel 230; the first outlet and the second outlet are respectively in communication with the backflow port through pipelines. The first outlet and the second outlet guide the fluids in the interlayer 110 and the heat exchange channel 121 to the backflow port, respectively, which not only ensures that the high-temperature fluid is fully recovered, but also avoids local fluid stagnation. At the same time, the fluid is re-injected into the interlayer 110 and the heat exchange channel 121 after being heated again by the second furnace body 200 during the backflow process, maintaining dynamic balance of the temperature field and realizing an efficient, stable and uniform heating process. In addition, the backflow fluid itself has a relatively high temperature, and only needs to be heated for a short time to reach the required temperature again, thereby shortening the heating time.
[0051] In this embodiment, a pressure relief valve is also provided on the pipeline to prevent excessive pressure in the pipeline from causing safety accidents.
[0052] As shown in Figure 4 and Figure 5 , the first furnace body 100 is provided with a uniform distribution disc 130 in communication with the outlet end of the channel 230; a plurality of first nozzles 131 are equidistantly arranged on one side of the uniform distribution disc 130, and the plurality of first nozzles 131 are located in the interlayer 110. The fluid entering the uniform distribution disc 130 from the outlet end of the channel 230 is uniformly sprayed into the interlayer 110 by the plurality of equidistantly arranged first nozzles 131, ensuring that the fluid in the interlayer 110 is uniformly distributed, and thereby better heating the black body source, ensuring uniform heating of the black body source.
[0053] In this embodiment, the first nozzles 131 can be 2, 3, 4, 5, 6 or more, which can be flexibly arranged according to the use requirements, and this embodiment does not limit it.
[0054] As shown in Figure 4 and Figure 5As shown, the side of the uniform distribution disc 130 is also provided with a second spray head 132, and the second spray head 132 is located in the heat exchange channel 121. The fluid entering the uniform distribution disc 130 from the outlet end of the channel 230 is also sprayed into the heat exchange channel 121 through the second spray head 132. The first spray head 131 and the second spray head 132 spray synchronously to form bidirectional heat flow coverage inside and outside, so that the surface temperature field of the blackbody source is globally balanced.
[0055] As shown in the figure, Figure 5 As shown, the uniform distribution disc 130 is provided with a first flow channel 133 communicated with the first spray head 131 and a second flow channel 134 communicated with the second spray head 132, and the first flow channel 133 and the second flow channel 134 are respectively communicated with the outlet end of the channel 230. A part of the high-temperature fluid flowing out of the outlet end of the channel 230 enters the first flow channel 133 and is sprayed into the interlayer 110 from the plurality of first spray heads 131, and another part of the high-temperature fluid enters the second flow channel 134 and is sprayed into the heat exchange channel 121 from the second spray head 132. Moreover, the first flow channel 133 and the second flow channel 134 are independent of each other and are respectively communicated with the outlet end of the channel 230, so that a flow regulating valve is arranged at the outlet end of the channel 230 to adjust the flow of the fluid entering the first flow channel 133 and the second flow channel 134 according to the demand.
[0056] As shown in the figure, Figure 3 As shown, the outer wall of the second furnace body 200 is wrapped with a heat preservation layer 250. The heat preservation layer 250 is arranged to isolate heat loss and reduce the interference of the external environment on the temperature of the fluid in the second furnace body 200.
[0057] As preferred in the embodiment, the heat preservation layer 250 is a refractory brick.
[0058] The second furnace body 200 is provided with a temperature sensor. The temperature sensor is arranged to monitor whether the fluid in the channel 230 is heated to the required temperature.
[0059] The outlet end of the channel 230 is provided with a valve. The valve is in a closed state when the fluid is just introduced into the channel 230. After the fluid is heated to the required temperature, the valve is opened to allow the fluid to flow into the first furnace body 100 to heat the blackbody source.
[0060] As shown in the figure, Figure 3 As shown, the metal piece 220 extends from one end of the channel 230 to the other end of the channel 230. By extending the metal piece 220 from one end of the channel 230 to the other end of the channel 230, the axial length of the metal piece 220 is as long as possible, and the contact area between the metal piece 220 and the fluid is larger, so that the heat exchange of the fluid is better.
