[0035] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0036] As described in the background art, during the operation of a nuclear reactor, cooling gas is usually used to absorb the heat generated in the fuel area and then carry it out for power generation. However, there is a problem of excessive heat dissipation during the energy conversion process, which reduces the energy conversion efficiency.

[0037] Please refer to Figure 1 and Figure 2 , the thermoacoustic conversion microreactor 100 with heat insulation function provided in the embodiments of the present invention can solve the above problems, and will be described in detail below.

[0038] The thermoacoustic conversion microreactor 100 with heat insulation function includes an outer housing 110 and an inner housing 130;

[0039] Among them, the outer housing 110 is sleeved around the inner housing 130 at intervals. In the inner cavity of the inner housing 130, a fuel area 140, an acoustic capacitance area 150, a conduction area 160, and a power generation area 170 are sequentially formed. The fuel area 140 is used for reacting to generate thermal radiation and sound waves. The acoustic capacitance area 150 is used for receiving sound waves and enhancing them. The conduction area 160 is used for receiving the enhanced sound waves and converting them into mechanical energy. The power generation area 170 is used for converting mechanical energy into electrical energy. The outer housing 110 is used for receiving the thermal radiation emitted by the inner housing 130 and reflecting it towards the fuel area 140.

[0040] During the working process, in addition to generating thermal radiation, the fuel area 140 can also generate sound waves. The sound waves can sequentially pass through the acoustic capacitance area 150 and the conduction area 160 and then be converted into electrical energy in the power generation area 170. At the same time, the outer housing 110 can reflect the thermal radiation flowing out of the inner housing 130 towards the fuel area 140, playing a heat preservation role while reducing heat loss, thereby improving the energy conversion efficiency.

[0041] It should be noted that during the reaction process in the fuel area 140, there will be a certain temperature difference. The temperature at the bottom end (i.e., the end far from the acoustic capacitance area 150) is relatively low, and the temperature at the top end (i.e., the end close to the acoustic capacitance area 150) is relatively high. In addition, since the cooling gas is a fluid, when it passes through the fuel area 140 with a temperature difference, the density and pressure of the cooling gas will change, resulting in the generation of sound waves, which can be understood as the thermoacoustic effect.

[0042] In addition to generating electricity using the self-heat energy of the fuel area 140, the thermoacoustic conversion micro-reactor 100 with heat preservation function can also utilize the temperature difference in the fuel area 140 to generate sound waves through the thermoacoustic effect and conduct them to the power generation area 170 for power generation, further improving the power generation efficiency.

[0043] Please refer to Figure 1 and Figure 2 , in order to reduce the heat dissipation between the inner housing 130 and the outer housing 110, a vacuum cavity 120 can be formed between the inner housing 130 and the outer housing 110. The thermal conductivity of the vacuum cavity 120 is almost 0, and its heat transfer method only exists in thermal radiation, thereby realizing the heat preservation effect on the inner housing 130 through thermal radiation.

[0044] Please refer to Figure 1 and Figure 2 , in order to improve the heat preservation effect on the inner housing 130, a reflective layer 115 can be provided on the inner wall of the outer housing 110, and the reflective layer 115 is made of a photonic crystal material.

[0045] Photonic crystals are materials with a periodic structure that can control the propagation and propagation characteristics of light. The uniqueness of this material stems from its internal microstructure, which can prohibit the propagation of light at specific wavelengths, thereby achieving the regulation of light. Photonic crystals can form a "photonic bandgap", similar to the electron bandgap in semiconductors. The photonic bandgap refers to the fact that within certain specific frequency ranges, photons cannot propagate in the material, and this property enables photonic crystals to exhibit very strong reflection and low loss at specific wavelengths.

[0046] In this embodiment, the reflective layer 115 includes a first reflective segment 116 and a second reflective segment 117 arranged at an angle. The first reflective segment 116 is used to receive the thermal radiation emitted by the fuel region 140 and reflect it towards the fuel region 140, and the second reflective segment 117 is used to receive the thermal radiation emitted by the acoustic capacitance region 150, the conduction region 160, and the power generation region 170 and reflect it towards the fuel region 140.

[0047] Moreover, since the thermal radiation at positions relatively far from the fuel region 140 is lower, in order to reduce the material cost, the thickness of the second reflective segment 117 can be gradually thinned along the direction away from the fuel region 140, and the thickness of the end of the second reflective segment 117 close to the fuel region 140 is the thickest. Regarding the thickness of the first reflective segment 116, its thickness can be made uniform and the same as the thickness of the end of the second reflective segment 117 close to the fuel region 140.

[0048] In this embodiment, the outer housing 110 can be made to have a structure that is thick in the middle and thin at both ends, that is, the top end of the first reflective segment 116 can be connected to the second reflective segment 117, the bottom end of the first reflective segment 116 can be connected to a third reflective segment, and both the second reflective segment 117 and the third reflective segment are inclined inward relative to the first reflective segment 116.

[0049] Please refer to Figure 1 and Figure 2 , in order to facilitate the flow of the cooling gas, the inner housing 130 can be provided with an intake hole 131 and an exhaust hole 132. The intake hole 131 is located on the side of the fuel region 140 away from the acoustic capacitance region 150, and the exhaust hole 132 is located between the fuel region 140 and the acoustic capacitance region 150. The intake hole 131 is used to input the cooling gas to absorb the thermal energy generated in the fuel region 140 and generate sound waves.

[0050] Similarly, the outer housing 110 is provided with an inlet and outlet channel for the cooling gas to penetrate and exit.

[0051] During the working process, the cooling gas can enter the fuel region 140 through the intake hole 131, move along the fuel region 140 from the bottom end to the top end direction, and then move out from the exhaust hole 132, and will penetrate through the outer housing 110 to take out the heat for conversion into electrical energy.

[0052] Please refer toFigure 1 and Figure 3 In the acoustic capacitance region 150, a bottom plate 151 and a plurality of straight cylinders 153 are provided. A guide hole 152 communicating with the plurality of straight cylinders 153 is formed in the bottom plate 151. The guide hole 152 and the inner cavity of the straight cylinder 153 jointly define an acoustic capacitance channel.

[0053] It should be noted that the acoustic capacitance region 150 generally has a specific set shape, and its size and shape are matched with the working frequency to form an acoustic wave resonance cavity, thereby enhancing the energy of the acoustic wave and strengthening the propagation of the acoustic wave therein.

[0054] In this embodiment, the bottom plate 151 is in the shape of a circular plate, the axial cross-section of the straight cylinder 153 is circular, and the guide hole 152 is a circular hole. The straight cylinder 153 is connected to the top end of the bottom plate 151, and the number of straight cylinders 153 connected to a single bottom plate 151 is multiple. The multiple straight cylinders are arranged in multiple groups along the circumferential direction of the bottom plate 151, and the number of straight cylinders 153 in different groups gradually decreases along the position closer to the center of the bottom plate 151.

[0055] Of course, in other embodiments of the present invention, the bottom plate 151 can be in the shape of a rectangular plate, a triangular plate or a rhombic plate structure, etc. The axial cross-section of the straight cylinder 153 can also be rectangular, triangular or rhombic, etc., and the corresponding guide hole 152 can also be a rectangular hole, a triangular hole or a rhombic hole, etc. The specific shapes of the bottom plate 151, the axial cross-section of the straight cylinder 153, and the guide hole 152 are not limited.

[0056] Please refer to Figure 1 and Figure 2 The thermoacoustic conversion micro-reactor 100 with heat insulation function further includes an inertia region 180. The inertia region 180 is located between the acoustic capacitance region 150 and the conduction region 160, and the inner diameter of the inertia region 180 is smaller than the inner diameter of the acoustic capacitance region 150.

[0057] It should be noted that the inertia region 180 mainly plays a role in affecting the compression and expansion speed of the gas, thereby realizing stable acoustic wave propagation and heat transfer; at the same time, it can balance the control of the gas flow speed and pressure. By controlling the gas flow in the inertia region 180, the propagation and energy exchange of the acoustic wave inside the device can be optimized, and the efficiency of thermoacoustic power generation can be improved.

[0058] Furthermore, the inner diameter of the acoustic capacitance region 150 can be understood as the comprehensive inner diameter of all the combined acoustic capacitance channels. The conduction channel of the inertia region 180 is one, corresponding to the acoustic capacitance channel located at the center of the acoustic capacitance region 150.

[0059] Please refer to Figure 1 and Figure 2, the conduction zone 160 is a metal bellows. During operation, it can transmit and regulate acoustic pressure fluctuations, and convert thermal energy into mechanical energy of the piston rod 173 by exciting the bellows to vibrate through high temperature. At the same time, the elastic design of the metal bellows can effectively relieve and absorb the changes in equipment expansion caused by high temperature, avoiding the impact of thermal expansion on the equipment.

[0060] Please refer to Figure 1 and Figure 2 , the power generation zone 170 is provided with a generator 171 and a piston rod 173. One end of the piston rod 173 is connected to the metal bellows, and the other end of the piston rod 173 is connected to the generator 171. When the metal bellows vibrates, it can drive the piston rod 173 to move axially, and then drive the generator 171 to convert mechanical energy into electrical energy to generate electricity.

[0061] An embodiment of the present invention also provides an operation method of a thermoacoustic conversion microreactor with a heat preservation function, which is realized by the thermoacoustic conversion microreactor 100 with a heat preservation function. The method includes:

[0062] Step S100: Control the fuel zone 140 to react and generate thermal radiation and sound waves;

[0063] Step S210: Control the acoustic capacitance zone 150 to conduct sound waves to the conduction zone 160;

[0064] Step S220: Control the conduction zone 160 to convert sound waves into mechanical energy, and then control the power generation zone 170 to convert mechanical energy into electrical energy;

[0065] Step S310: Control the outer housing 110 to receive the thermal radiation emitted by the inner housing 130 and reflect it towards the fuel zone 140.

[0066] It should be noted that the above step S310 can be carried out simultaneously with step S210 and step S220.

[0067] In summary, the thermoacoustic conversion microreactor 100 with a heat preservation function and the operation method of the thermoacoustic conversion microreactor with a heat preservation function provided by the embodiments of the present invention at least have the following advantages:

[0068] (1). In addition to generating thermal radiation, the fuel zone 140 of the thermoacoustic conversion microreactor 100 with a heat preservation function can also generate sound waves. The sound waves can pass through the acoustic capacitance zone 150 and the conduction zone 160 in sequence and then be converted into electrical energy in the power generation zone 170. At the same time, the outer housing 110 can reflect the thermal radiation flowing out of the inner housing 130 towards the fuel zone 140, playing a heat preservation role while reducing heat loss, thereby improving the energy conversion efficiency.

[0069] (2) The thermoacoustic conversion micro-reactor 100 with heat insulation function can reflect the thermal radiation emitted by the inner housing 130 through the reflective layer 115 provided on the inner wall of the outer housing 110, so that the reflected thermal radiation is concentrated in the fuel area 140, thereby improving the heat insulation effect on the fuel area 140 and reducing heat loss.

[0070] (3) By reflecting and concentrating the heat to the fuel area 140, the thermoacoustic conversion micro-reactor 100 with heat insulation function also helps to increase the temperature difference at both ends of the fuel area 140, thereby promoting the thermoacoustic effect, making the mechanical energy caused by the generated sound wave passing through the conduction area 160 greater, and then converting more electrical energy by the power generation area 170.

[0071] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
