Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments.

[0037] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an ordered ranking of the indicated technical features. Thus, features defined with "first", "second" or "third" can explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise expressly and specifically defined.

[0038] In order to make the purposes, technical solutions and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples.

[0039] In the heat pipe reactor power supply, a Stirling generator is usually used as its thermoelectric conversion subsystem, which is a thermoelectric conversion device based on Stirling cycle, and its theoretical efficiency is equal to Carnot efficiency, and it adopts a gap sealing structure, eliminates piston lateral force, reduces mechanical wear, and has a long maintenance-free operation life of more than ten years, so it is a high-efficiency and high-reliability thermoelectric conversion device, which has been widely used in the field of nuclear reactors in recent years.

[0040] The Stirling generator usually adopts a double-machine-opposed mode to form a power generation unit, and the hot heads of the two Stirling machines are concentrated together to facilitate heat supply, and a heat pipe is used as a heat transfer mode to form a heat pipe reactor.

[0041] However, in the heat pipe reactor, in order to avoid the destructive effect of high radiation of the reactor on the Stirling generator, a shielding layer must be arranged between the two, and because of the existence of the shielding layer, the arrangement of the heat pipe can only choose to bypass the shielding layer. In order to bypass the shielding layer, the heat pipe needs to be bent multiple times and then coupled to the hot head device of the Stirling machine for heat supply. The multiple bending of the heat pipe reduces the heat transfer capacity of the heat pipe by 28.4% to 43.2%, which significantly weakens the heat transfer performance of the heat pipe. In order to reduce the influence of bending, the bending fillet radius is usually designed to be large, which significantly increases the length of the heat pipe, which is not conducive to the space arrangement of the heat pipe reactor.

[0042] In the embodiment of the present application, the Stirling generator device and the reactor are arranged horizontally, the radiation shielding layer is arranged between the Stirling generator device and the reactor, and is arranged vertically to the Stirling generator device and the reactor. This arrangement reduces the length and the number of bends of the heat pipe device to the minimum, fully utilizes the heat transfer performance of the heat pipe device, and improves the space compactness of the heat pipe reactor power supply system.

[0043] The heat pipe reactor power supply system of the present application is described below in combination with Figures 1 to 6 The heat pipe reactor power supply system of the present application is described below in combination with

[0044] As Figure 1 and Figure 2As shown, the heat pipe reactor power supply system provided by some embodiments of the present application comprises a reactor 1, a Stirling generator device 2, a radiation shielding layer 3 and a heat pipe device 4, the reactor 1 is a nuclear reactor and can generate heat energy, the reactor 1 can be selected as Figure 1 , the Stirling generator device 2 is horizontally arranged and the axis of the Stirling generator device 2 is parallel to the axis of the reactor 1, the Stirling generator device 2 can perform thermoelectric conversion, the radiation shielding layer 3 is a three-dimensional structure with an axis, the radiation shielding layer 3 is arranged between the reactor 1 and the Stirling generator device 2, the radiation shielding layer 3 is used to avoid the destructive effect of high radiation of the reactor 1 on the Stirling generator device 2, the axis of the radiation shielding layer 3 is perpendicular to the axis of the reactor 1, the heat pipe device 4 bypasses the radiation shielding layer 3 and is arranged between the reactor 1 and the Stirling generator device 2, the heat pipe device 4 is used to transfer the heat energy of the reactor 1 to the Stirling generator device, one end of the heat pipe device 4 connected to the reactor 1 is an evaporation section and is used to absorb the heat energy generated by the reactor 1, and the other end of the heat pipe device 4 connected to the Stirling generator device 2 is a condensation section and is used to release heat to the Stirling generator device 2 for thermoelectric conversion. The thermoelectric conversion principle of the Stirling generator device 2 is to convert heat energy into electric energy by using the Stirling cycle principle, and the specific details are not described here.

[0045] In the embodiments of the present application, the Stirling generator device 2 and the reactor 1 are horizontally arranged, the radiation shielding layer 3 is arranged between the Stirling generator device 2 and the reactor 1 and is perpendicular to the Stirling generator device 2 and the reactor 1, which reduces the length and the number of bends of the heat pipe device 4 to the minimum, fully plays the heat transfer performance of the heat pipe device 4, and improves the space compactness of the heat pipe reactor power supply system.

[0046] In some embodiments of the present application, the Stirling generator device 2 comprises a plurality of Stirling generators 21, the number of the Stirling generators 21 is even, and each two Stirling generators 21 are symmetrically arranged with the plane where the axis of the radiation shielding layer 3 is located as the center plane. Figure 1 , Figure 2 and Figure 5As shown in the figure, the Stirling generator device 2 comprises two Stirling generators 21 symmetrically arranged with the axis of the radiation shielding layer 3 as the center plane, and the two Stirling generators 21 are symmetrically arranged to reduce the vibration during the operation of the Stirling generator 21. Each Stirling generator 21 comprises a hot head 22 arranged at one end and a back cavity 23 arranged at the other end, and the two symmetrically arranged Stirling generators 21 are connected through the back cavities 23. Due to the reciprocating motion inside the Stirling generator 21, vibration problems of the Stirling generator 21 are inevitably caused, and the vibration will cause many problems such as reduced reliability and performance of the system. In order to solve the vibration problem, the Stirling generator device 2 adopts a double-machine opposing mode to form a power generation unit, that is, the two Stirling generators 21 of the Stirling generator device 2 are symmetrically arranged, and the two Stirling generators 21 are connected in a manner that the back cavities 23 are communicated, so that the hot heads 22 of the two Stirling generators 21 are arranged at both ends of the axis, and the axis of the Stirling generator 21 and the reactor 1 are both horizontally arranged, which is beneficial to the connection of the heat pipe device 4, thereby reducing the length and the number of bends of the heat pipe device 4 to the minimum, fully exerting the heat transfer performance of the heat pipe device 4, and improving the space compactness of the heat pipe reactor power supply system.

[0047] In some embodiments of the present application, the heat pipe device 4 comprises a first heat pipe assembly 41 and a second heat pipe assembly 42 symmetrically arranged with the axis of the radiation shielding layer 3 as the symmetry plane, that is, the two ends of the axis of the reactor 1 are respectively connected with the first heat pipe assembly 41 and the second heat pipe assembly 42, wherein one end of the first heat pipe assembly 41 is connected with one end of the reactor 1, the other end of the first heat pipe assembly 41 is connected with the hot head 22 of the corresponding Stirling generator 21, one end of the second heat pipe assembly 42 is connected with the other end of the reactor 1, and the other end of the second heat pipe assembly 42 is connected with the hot head 22 of the corresponding Stirling generator 21, so as to symmetrically arrange the two Stirling generators 21 and symmetrically arrange the two heat pipe assemblies. On the one hand, the length and the number of bends of the heat pipe assembly are reduced to the minimum, the heat transfer performance of the heat pipe assembly is fully exerted, and on the other hand, the heat energy transmission is simultaneously performed on both sides of the Stirling generator device 2, thereby accelerating the power generation efficiency of the heat pipe reactor power supply system.

[0048] In some embodiments of the present application, the first heat pipe assembly 41 and the second heat pipe assembly 42 each comprise a plurality of heat pipe structures 43 arranged side by side, and the heat pipe structure 43 is used for transferring the heat energy of the reactor 1 to the symmetrically arranged Stirling generator 21 for power generation. In some optional embodiments, the heat pipe structure 43 is preferably arranged in three, and three are symmetrically arranged, and the heat energy transmission is simultaneously performed, thereby accelerating the power generation efficiency of the heat pipe reactor power supply system.

[0049] In some optional embodiments of the present application, the heat pipe structure 43 comprises a first-stage heat pipe component 431 and a second-stage heat pipe component 432, one end of the first-stage heat pipe component 431 is coupled to the reactor 1, the other end of the first-stage heat pipe component 431 is coupled to one end of the second-stage heat pipe component 432, the first-stage heat pipe component 431 is used for long-distance transportation of heat energy of the reactor 1, and the other end of the second-stage heat pipe component 432 is coupled to the hot head 22 of the Stirling generator 21. Since the existing heat pipe is cylindrical, it is difficult to be directly coupled to the hot head 22 of the Stirling generator 21, and an additional coupling device such as a heat collecting block or the like is needed, or the condenser section of the heat pipe is directly processed into a circular ring structure, which will increase the thermal resistance between the heat pipe and the hot head 22, or increase the difficulty and complexity of manufacturing the heat pipe.

[0050] In the present embodiment, the coupling mode of the first-stage heat pipe component 431 and the second-stage heat pipe component 432 can reduce the bending times of the first-stage heat pipe component 431, as shown in Figure 1 and Figure 2 , the first-stage heat pipe component 431 only needs to be simply bent once, has a regular shape, is easy to manufacture, and maximizes the performance of the first-stage heat pipe component 431, and the presence of the second-stage heat pipe component 432 can serve as an intermediate medium to couple the first-stage heat pipe component 431 and the hot head 22 for heat transfer, solve the problem of difficult connection of the cylindrical heat pipe and the hot head 22, and improve the compactness of the entire heat pipe reactor power supply system.

[0051] Specifically, the first-stage heat pipe component 431 is a cylindrical heat pipe, i.e. the existing heat pipe structure, and the second-stage heat pipe component 432 is a closed hollow cylindrical structure, as shown in Figure 3 and Figure 4 , the side wall of the hollow cylinder is provided with an inwardly recessed heat conduction channel 433, i.e. the axis of the heat conduction channel 433 is arranged in parallel with the axis of the radiation shielding layer 3, the heat conduction channel 433 can penetrate the hollow cylinder, and the other end of the first-stage heat pipe component 431 is arranged in the heat conduction channel 433, so that the first-stage heat pipe component 431 connected out of the reactor 1 is directly inserted into the heat conduction channel 433, reducing the bending times of the first-stage heat pipe component 431, and using the heat conduction channel 433 of the second-stage heat pipe component 432 for heat transfer coupling can release the maximum heat transfer capacity of the entire system.

[0052] In some optional embodiments, as shown in Figure 2 , the axis of the heat conduction channel 433 is arranged in parallel with the axis of the Stirling generator 21, which is convenient for adjusting the spatial layout of the entire heat pipe reactor power supply system.

[0053] In some embodiments of the present invention, the inner wall of the hollow cylinder and the outer wall of the heat conduction channel 433 are both porous wicking structures, and the hollow cylinder is filled with a liquid heat-conducting medium. The liquid heat-conducting medium can be selected from liquid lithium metal, liquid sodium metal, and liquid potassium metal, etc. The condensing section of the first-stage heat pipe component 431 is inserted into the heat conduction channel 433, transferring heat energy to the second-stage heat pipe component 432. At this time, the inner wall of the heat conduction channel 433 is equivalent to the evaporation surface. The liquid heat-conducting medium filled in the hollow cylinder carries away heat at the evaporation surface, condenses and releases heat energy at the hot head 22 of the Stirling generator 21, and the condensed heat-conducting medium flows back to the evaporation surface through the porous wicking structure, thus completing the heat transfer. The porous wicking structure generates capillary pressure, which is then used to drive the liquid heat-conducting medium from the condensation surface to the evaporation surface, maintaining the operation of the cooling system. Common types of wicking cores include sintered metal powder wicking cores, wire mesh wicking cores, and grooved or channel wicking cores. The specific type of wicking core used is not limited in this embodiment. The porous structure of the wicking core provides a return channel for the heat transfer medium, reducing the return resistance and thus improving the heat transfer performance of the heat pipe.

[0054] In some alternative embodiments, such as Figure 5 As shown, the heat pipe structure 43 is a cylindrical heat pipe. One end of the cylindrical heat pipe is coupled to the reactor 1, and the other end is coupled to the hot head 22 of the Stirling generator 21. In this layout, the second-stage heat pipe component 432 is omitted. The heat pipe structure 43, which extends from the reactor 1, is directly connected to the hot head 22 of the Stirling generator 21 after two bends. Compared with the layout in the previous embodiment, this layout adds one bend and reduces the use of the second-stage heat pipe component 432. In comparison, the increase in bends is negative, but reducing the use of the second-stage heat pipe component 432 simplifies the structure and facilitates adjustments to the spatial layout of the entire heat pipe reactor power system.

[0055] like Figure 6As shown, in some embodiments of the present invention, each Stirling generator 21 further includes a housing 211, a phase adjuster 212, and a power piston 213. The phase adjuster 212 is disposed within the housing 211 and is provided with a connecting rod 214. The power piston 213 is disposed within the housing 211, and a back cavity 23 is separated between the power piston 213 and the phase adjuster 212. The heat head 22 is disposed within the housing 211 and on the side away from the back cavity 23. The connecting rod 214 is slidably connected to the power piston 213. When the Stirling generator 21 is generating electricity, the heat pipe structure 43 transfers heat energy to the heat head 22, and pressure fluctuations are generated in the back cavity 23. These pressure fluctuations drive the power piston 213 to reciprocate. The phase adjuster 212 couples the connecting rod 214 with the power piston 213 through the action of gas, thereby transferring energy. The connecting rods 214 of two symmetrically arranged Stirling generators 21 are connected by an elastic connector 215. In this embodiment, the effective coupling and vibration damping of the back cavities 23 of the two symmetrically arranged Stirling generators 21 is crucial for the overall power generation of the system. With the Stirling generators 21 symmetrically arranged, the pressure fluctuations in the back cavities 23 are consistent, causing the power pistons 213 to automatically move in opposite directions. To ensure that the two power pistons 213 move completely in opposite directions, the connecting rods 214 of the two symmetrically arranged Stirling generators 21 are connected by an elastic connector 215, thereby achieving a better vibration damping effect for the moving parts of the two Stirling generators 21. Furthermore, connecting the back cavities 23 of the two symmetrically arranged Stirling generators 21 also improves the coupling between them, ensuring that the internal moving parts move in opposite directions, achieving a better vibration damping effect. The elastic connector 215 can be a spring or a torsion spring, etc.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
