Description

Technical Field

[0001] The invention relates to a controller and method based on cylindrical waveguide, belonging to the technical field of radiation heat transport control. Background Art

[0002] When the distance between two interacting objects is less than or equal to the characteristic wavelength of thermal emission, photon-mediated radiative heat transfer mainly occurs in the near-field region. Due to the excitation of surface evanescent modes (surface plasmons and surface phonons) between interacting objects, near-field radiative heat transfer is much higher than the conventional Planck blackbody radiation limit. In recent years, with the rapid development of micro-nanotechnology, materials science, and quantum physics, near-field radiative heat transfer has shown potential application prospects in the energy management of high-power non-contact optoelectronic devices. In addition, actively regulating the energy transfer process can not only meet the specific heat requirements of the equipment under different working conditions, but also help to extend the working life, which is a key link in achieving efficient operation of micro-nano devices. However, inventions related to the field of near-field radiative heat regulation still have technical problems such as poor regulation performance and a small adjustment range. For example: the publication number is CN106546122A, the name of the invention is a near-field radiation heat exchange heat regulator and adjustment method, and its technical solution is a near-field heat regulator based on a two-body disk structure. By adjusting the relative angle of the two interacting disks, the heat between them is controlled. Without changing the positions of the two interacting objects, its accuracy and adjustment range are small. Recently, cylindrical waveguides that support low-loss localized surface modes can directionally guide the propagation of electromagnetic waves and have attracted widespread attention in the fields of electromagnetic and communication engineering. With the advancement of micro-nanoscale non-contact heat transport technology and the development of electromagnetic thermal radiation theory, cylindrical waveguide structures have shown great application potential in the field of active manipulation of electromagnetic energy transmission between objects. The publication number is CN115289890A, and the name of the invention is a structure based on hyperbolic materials to regulate near-field radiation heat exchange. Its technical solution adopts a planar substrate structure with large propagation losses.

[0043] Specific implementation method eight: Combination Figure 1 7 illustrates this embodiment, which is a torsional near-field radiation heat transport controller based on a cylindrical waveguide. The driving device, transmitting end 5, waveguide structure 6, receiving end 9, hydraulic cylinder, motor and other adjustable devices of the platform 4 are all electrically connected to the control system 10 (a control and signal receiving device of a torsional near-field radiation heat transport controller based on a cylindrical waveguide) through a wire 8;

[0044] The present invention utilizes a cylindrical waveguide structure to provide a heat transfer channel controlled by an electromagnetic surface mode for heat exchange between a transmitting end and a receiving end, which is essentially different from a planar substrate structure. Compared with the planar substrate structure, the cylindrical waveguide structure adopted by the present invention can realize axial directional transmission of electromagnetic energy and has the advantage of lower propagation loss. Therefore, for the same material and characteristic size, the cylindrical waveguide structure has better heat transfer characteristics.

[0045] Specific implementation method nine: Combination Figure 1-7 The present embodiment is described. A method for regulating torsional near-field radiation heat transport based on a cylindrical waveguide is provided in the present embodiment. The torsional near-field radiation heat transport regulator based on a cylindrical waveguide is used to achieve precise regulation of non-contact radiation energy transport at a micro / nano scale. A device for actively regulating cylindrical electromagnetic energy transmission by a torsional method comprises: a transmitting end, a receiving end, a cylindrical waveguide structure, a nano-displacement device, a base structure for fixing other devices at the top and bottom, and a control and signal receiving device for the entire system. The present invention provides a directional heat transfer channel controlled by cylindrical surface plasmons or surface phonons for energy exchange between the transmitting end and the receiving end, and uses a nano-displacement device to adjust the excitation of the cylindrical surface mode, thereby actively regulating the energy exchange process between the transmitting end and the receiving end.

[0046] The bottom U-shaped substrate structure is used to support a cylindrical waveguide structure with a radius of R; the top fixed structure is connected to a nano-displacement platform, which can arbitrarily adjust the rotation angle α and the vertical distance z0 between the transmitting end and the receiving end and the waveguide structure; and the horizontal displacement platform can be used to adjust the horizontal distance d between the transmitting end and the receiving end; the two platforms are connected through an intermediate disk; in addition, the adjustable devices are all connected to the control system through wires; the cylindrical waveguide structure is fixed with a U-shaped substrate structure, which can reduce the near-field interaction between the waveguide and the substrate, thereby improving the electromagnetic energy transmission and regulation capabilities of the waveguide structure;

[0047] The transmitting end and the receiving end can be made of nanoparticles of any isotropic (dielectric or metal) and anisotropic materials; wherein the radius of the particles is 5-1000nm; in this embodiment, both the transmitting end and the receiving end use SiC nanoparticles with a radius of 5nm;

[0048] The waveguide structure can be made of any isotropic (dielectric or metal) and anisotropic material; wherein the radius is 0.01-10 μm, and the length should be much larger than the horizontal distance d between the transmitting end and the receiving end; the present invention demonstrates the thermal regulation characteristics of silicon carbide (SiC) and gold (Au) cylindrical waveguides in the embodiments;

[0049] The horizontal distance d and the vertical distance z0 should be greater than or equal to four times the radius of the nanoparticle; therefore, the range of d and z0 is 20-4000nm; wherein the horizontal distance d can be adjusted by the horizontal displacement platform, and the vertical distance z0 can be adjusted by the nano displacement platform;

[0050] The present invention designs and adopts a U-shaped substrate fixed cylindrical waveguide structure, which can reduce the near-field interaction between the waveguide and the substrate, thereby enhancing the energy transmission and regulation capabilities of the waveguide;

[0051] The present invention uses a nano displacement platform to adjust the position of the upper system, and changes the rotation angle α between the line connecting the transmitting end and the receiving end and the axis of the waveguide structure, so as to control the radiation heat flow between objects; wherein, based on the principle of symmetry, the range of the rotation angle α is preferably 0-90°; the mechanical rotation point O is located in the middle of the line connecting the transmitting end and the receiving end;

[0052] Figure 2 The relationship between the rotation angle and the radiation thermal conductivity h under fixed parameters d = 1μm, z0 = 50nm and R = 0.1μm is shown. It can be seen from the figure that compared with the vacuum case, the existence of the cylindrical waveguide can regulate the heat exchange between objects; when the material of the waveguide structure is SiC, the regulation ratio of the heat exchange between the transmitting end and the receiving end (the ratio of the maximum value to the minimum value) exceeds four orders of magnitude; this shows that the SiC cylindrical waveguide structure has a huge thermal regulation ability;

[0053] Figure 3 and Figure 4 The relationship between the horizontal spacing d and the radiative thermal conductance h of the SiC cylindrical waveguide structure and the Au cylindrical waveguide structure under fixed parameters z0 = 50nm and R = 0.1μm is shown respectively; for a smaller d, all cases are basically equal in value; with the increase of d, the thermal regulation performance of the cylindrical waveguide gradually becomes prominent; this shows that the regulation ability of the waveguide is closely related to the horizontal spacing d and the waveguide radius R; as d continues to increase, the cases where α is greater than 0° gradually converge, which shows that at a larger spacing, the adjustable performance of the heat flow is more sensitive to the rotation angle requirements; therefore, in the actual processing process, the design of the cylindrical waveguide structure should comprehensively consider the relationship between the spacing d and the radius R;

[0054] Figure 5 The relationship between the radius R and the radiation thermal conductivity h of the SiC cylindrical waveguide structure at different rotation angles α is shown; it can be found that with the increase of R, h basically shows a trend of first increasing and then decreasing; there is an optimal radius at the different rotation angles; therefore, the radius of the waveguide structure is particularly critical to the adjustable performance;

[0055] Figure 6 The relationship between the vertical spacing z0 and the radiative thermal conductivity of the SiC cylindrical waveguide structure at different angles α is shown; as z0 increases, the radiative thermal conductivity h gradually decreases in all cases, but the rate of decrease is different; the larger α is, the slower the rate of decrease; the size of z0 is directly related to the excitation of the near-field surface mode, so this confirms the possibility of regulating the radiative heat transfer between objects by adjusting the cylindrical surface mode;

[0056] A method for regulating torsional near-field radiation heat transport based on cylindrical waveguides comprises the following steps: adjusting the relative angle between the line connecting the transmitting end and the receiving end and the axis of the cylindrical waveguide structure, thereby realizing active regulation of the radiation heat flow between objects; in an isolated state, the electromagnetic energy transmission between the transmitting end 5 and the receiving end 9 is mediated by photons; using the cylindrical waveguide (waveguide structure 6) to provide a heat transfer channel (heat channel 2) controlled by the electromagnetic surface mode for the energy exchange between the two, and using a nano-displacement device (turntable 2 and hydraulic cylinder) to accurately control the interaction between the objects, thereby efficiently regulating the energy transfer process between the transmitting end 5 and the receiving end 9; the present invention introduces a cylindrical waveguide structure for the transmitting end and the receiving end The heat exchange between the two ends provides a new heat transport channel, thereby regulating the heat exchange between them, which is essentially different from the idea of ​​the prior art; different from the method of adjusting the relative angle of two interacting disks to achieve heat regulation between them: the present invention adjusts the relative angle between the two interacting particles (the transmitting end and the receiving end) and the cylindrical waveguide structure (the third object) to achieve heat regulation between the transmitting end and the receiving end; compared with the prior art, the present invention has the advantage of accurately regulating heat without changing the positions of the two interacting objects, and in the present invention, due to the introduction of the cylindrical waveguide, the adjustable range of the distance between the two objects is also larger;

[0057] The present invention provides a torsional near-field radiation heat transport regulator based on a cylindrical waveguide; the regulator can effectively regulate the radiation heat conduction between a transmitting end and a receiving end by means of mechanical torsion, thereby achieving a better radiation heat flow regulation effect.

Therefore, the present invention will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present invention.
