Description

Technical Field

[0001] The invention relates to the technical field of nuclear reactor system design, and in particular to a heat pipe reactor power supply system. Background Art

[0002] In heat pipe reactor power sources, Stirling generators are usually used as their thermoelectric conversion subsystem. Stirling generators are a type of thermoelectric conversion device based on the Stirling cycle. Their theoretical efficiency is equal to the Carnot efficiency, and they use a gap sealing structure to eliminate the lateral force of the piston and reduce mechanical wear. Their maintenance-free operating life can be as long as more than ten years. Therefore, they are a type of thermoelectric conversion device with high efficiency and reliability. In recent years, they have been widely used in the field of nuclear reactors.

[0003] Stirling generators usually use two machines facing each other to form a power generation unit. The heat heads of the two Stirling machines are concentrated together to facilitate heating, and heat pipes are used as a heat transfer method to form a heat pipe reactor.

[0004] However, in a heat pipe reactor, in order to prevent the high radiation of the reactor from damaging the Stirling generator, a shielding layer must be set between the two. Due to the existence of the shielding layer, the layout 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 connected to the thermal head device of the Stirling machine for coupled heating. The multiple bending of the heat pipe reduces the heat transfer capacity of the heat pipe by 28.4% to 43.2%, which will significantly weaken the heat transfer performance of the heat pipe. In order to reduce the impact of bending, the bending radius is usually designed to be larger, which will significantly increase the length of the heat pipe, which is not conducive to the spatial layout of the heat pipe reactor.

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] In heat pipe reactor power sources, Stirling generators are usually used as their thermoelectric conversion subsystem. Stirling generators are a type of thermoelectric conversion device based on the Stirling cycle. Their theoretical efficiency is equal to the Carnot efficiency, and they use a gap sealing structure to eliminate the lateral force of the piston and reduce mechanical wear. Their maintenance-free operating life can be as long as more than ten years. Therefore, they are a type of thermoelectric conversion device with high efficiency and reliability. In recent years, they have been widely used in the field of nuclear reactors.

[0040] Stirling generators usually use two machines facing each other to form a power generation unit. The heat heads of the two Stirling machines are concentrated together to facilitate heating, and heat pipes are used as a heat transfer method to form a heat pipe reactor.

[0041] However, in a heat pipe reactor, in order to prevent the high radiation of the reactor from damaging the Stirling generator, a shielding layer must be set between the two. Due to the existence of the shielding layer, the layout 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 connected to the thermal head device of the Stirling machine for coupled heating. The multiple bending of the heat pipe reduces the heat transfer capacity of the heat pipe by 28.4% to 43.2%, which will significantly weaken the heat transfer performance of the heat pipe. In order to reduce the impact of bending, the bending radius is usually designed to be larger, which will significantly increase the length of the heat pipe, which is not conducive to the spatial layout of the heat pipe reactor.

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

[0043] Combine the following Figures 1 to 6 The heat pipe reactor power system of the present invention is described.

[0044] like Figure 1 and Figure 2As shown, the heat pipe reactor power supply system provided in some embodiments of the present invention includes 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 that can generate heat energy. The reactor 1 can be selected as follows: Figure 1 The structure is placed horizontally, the axis of the Stirling generator device 2 is arranged 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 prevent the high radiation of the reactor 1 from damaging the Stirling generator device 2, the axis of the radiation shielding layer 3 is arranged 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, the end of the heat pipe device 4 connected to the reactor 1 is the evaporation section, which is used to absorb the heat energy generated by the reactor 1, and the end connected to the Stirling generator device 2 is the condensation section, which 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 electrical energy using the Stirling cycle principle, and the specific details are not repeated.

[0045] In an embodiment of the present invention, the Stirling generator device 2 and the reactor 1 are horizontally arranged, and the radiation shielding layer 3 is arranged between the Stirling generator device 2 and the reactor 1, and is arranged perpendicular to the Stirling generator device 2 and the reactor 1. This arrangement reduces the length and the number of bends of the heat pipe device 4 to a minimum, fully utilizes the heat transfer performance of the heat pipe device 4, and also improves the spatial compactness of the heat pipe reactor power supply system.

[0046] In some embodiments of the present invention, the Stirling generator device 2 includes a plurality of Stirling generators 21, the number of the Stirling generators 21 is an even number, and every two Stirling generators 21 are arranged symmetrically with the plane where the axis of the radiation shielding layer 3 is located as the center plane. In this embodiment, Figure 1 , Figure 2 and Figure 5As shown in the figure, the Stirling generator device 2 includes two Stirling generators 21 symmetrically arranged with the plane where the axis of the radiation shielding layer 3 is located as the center plane. The two Stirling generators 21 are symmetrically arranged to reduce the vibration of the Stirling generators 21 during operation. Each Stirling generator 21 includes a thermal head 22 arranged at one end and a back cavity 23 arranged at the other end. The two symmetrically arranged Stirling generators 21 are connected through the back cavity 23. Due to the reciprocating motion characteristics of the Stirling generator 21, it is inevitable that the Stirling generator 21 will have vibration problems, and 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 dual-machine opposing method to form a power generation unit, that is, the Stirling generator device 2 has two symmetrically arranged Stirling generators 21, and the two Stirling generators 21 are connected by a back cavity 23, so that the heat heads 22 of the two Stirling generators 21 are arranged at both ends of the axis, and the axes of the Stirling generator 21 and the reactor 1 are both arranged horizontally, which is convenient for the access of the heat pipe device 4, thereby reducing the length and bending times of the heat pipe device 4 to a minimum, giving full play to the heat transfer performance of the heat pipe device 4, and also improving the spatial compactness of the heat pipe reactor power supply system.

[0047] In some embodiments of the present invention, the heat pipe device 4 includes a first heat pipe assembly 41 and a second heat pipe assembly 42 which are symmetrically arranged with the plane where the axis of the radiation shielding layer 3 is located as the symmetry plane, that is, the first heat pipe assembly 41 and the second heat pipe assembly 42 are respectively connected to the two ends of the axis of the reactor 1, wherein one end of the first heat pipe assembly 41 is connected to one end of the reactor 1, and the other end of the first heat pipe assembly 41 is connected to the hot head 22 of the Stirling generator 21 on the corresponding side, one end of the second heat pipe assembly 42 is connected to the other end of the reactor 1, and the other end of the second heat pipe assembly 42 is connected to the hot head 22 of the Stirling generator 21 on the corresponding side, two Stirling generators 21 are symmetrically arranged with the symmetry plane, and two groups of heat pipe assemblies are symmetrically arranged. On the one hand, the length and bending times of the heat pipe assembly are reduced to a minimum, and the heat transfer performance of the heat pipe assembly is fully utilized. On the other hand, heat energy is transmitted simultaneously on both sides of the Stirling generator device 2, which speeds up the power generation efficiency of the heat pipe reactor power supply system.

[0048] In some embodiments of the present invention, the first heat pipe assembly 41 and the second heat pipe assembly 42 each include a plurality of heat pipe structures 43 arranged in parallel, and the heat pipe structures 43 are used to transfer the heat energy of the reactor 1 to the symmetrically arranged Stirling generator 21 for power generation. In some optional embodiments, three heat pipe structures 43 are preferably arranged, and three are symmetrically arranged to perform heat energy transmission simultaneously, thereby accelerating the power generation efficiency of the heat pipe reactor power system.

[0049] In some optional embodiments of the present invention, the heat pipe structure 43 includes 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 heat head 22 of the Stirling generator 21. Since the existing heat pipe is cylindrical, it is difficult to directly couple it with the heat head 22 of the Stirling generator 21, and it is necessary to use additional coupling devices, such as heat collection blocks and other components, or directly process the heat pipe condensation section into a circular ring structure, and the former will increase the thermal resistance between the heat pipe and the heat head 22, and the latter will increase the difficulty and complexity of heat pipe manufacturing.

[0050] In this embodiment, the first-stage heat pipe component 431 and the second-stage heat pipe component 432 are coupled to each other to reduce the number of bending times of the first-stage heat pipe component 431. Figure 1 and Figure 2 As shown, the first-stage heat pipe component 431 only requires one simple bend, has a regular shape, and is simple to manufacture, thereby maximizing the performance of the first-stage heat pipe component 431. The existence of the second-stage heat pipe component 432 can serve as an intermediate medium to couple the first-stage heat pipe component 431 with the thermal head 22 for heat transfer, thereby solving the problem of difficulty in connecting the cylindrical heat pipe with the thermal head 22, and also improving the compactness of the entire heat pipe reactor power system.

[0051] Specifically, the first-stage heat pipe component 431 is a cylindrical heat pipe, that is, an existing heat pipe structure, and the second-stage heat pipe component 432 is a closed hollow cylindrical structure, such as Figure 3 and Figure 4 As shown, a concave heat-conducting channel 433 is provided on the side wall of the hollow cylinder, that is, the axis of the heat-conducting channel 433 is arranged parallel to the axis of the radiation shielding layer 3, and the heat-conducting channel 433 can pass through the hollow cylinder. The other end of the first-stage heat pipe component 431 is arranged in the heat-conducting channel 433, so that the first-stage heat pipe component 431 connected by the reactor 1 is directly inserted into the heat-conducting channel 433, reducing the number of bending times of the first-stage heat pipe component 431, and utilizing the heat-conducting channel 433 of the second-stage heat pipe component 432 for heat transfer coupling, which can release the maximum heat transfer capacity of the entire system.

[0052] In some optional embodiments, such as Figure 2 As shown, the axis of the heat conduction channel 433 is arranged parallel to the axis of the Stirling generator 21, which facilitates the adjustment of the spatial layout of the entire heat pipe reactor power 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 wick structures, and the hollow cylinder is filled with liquid heat conducting medium. The liquid heat conducting medium can be selected from liquid metal lithium, liquid metal sodium and liquid metal potassium. The condensation section of the first-stage heat pipe component 431 is inserted into the heat conduction channel 433 to transfer 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 takes away heat on the evaporation surface, condenses and releases heat energy at the heat head 22 of the Stirling generator 21, and the condensed heat conducting medium flows back to the evaporation surface through the porous wick structure, thus completing the transfer of heat energy. The porous wick structure will generate capillary pressure, which is then used to drive the liquid heat conducting medium to move from the condensation surface to the evaporation surface to maintain the operation of the cooling system. At present, common types of wicks include metal powder sintered wicks, wire mesh wicks, and groove or channel wicks. The specific wick types used are not limited in this embodiment. The porous structure of the wick provides a reflux channel for the heat-conducting medium, reduces the reflux resistance of the heat-conducting medium, and thus improves the heat transfer performance of the heat pipe.

[0054] In some optional embodiments, such as Figure 5 As shown, the heat pipe structure 43 is a cylindrical heat pipe, one end of which is coupled to the reactor 1, and the other end of which is coupled to the heat head 22 of the Stirling generator 21. In this layout, the second-stage heat pipe component 432 is omitted, and the heat pipe structure 43 connected from the reactor 1 is directly connected to the heat head 22 of the Stirling generator 21 after being bent twice. 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 can simplify the structure and facilitate the adjustment of 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 also includes a housing 211, a phase modulator 212 and a power piston 213, the phase modulator 212 is arranged in the housing 211 and is provided with a connecting rod 214, the power piston 213 is arranged in the housing 211, a back cavity 23 is separated between the power piston 213 and the phase modulator 212, the thermal head 22 is arranged in the housing 211 and away from the side of the back cavity 23, the connecting rod 214 is slidably connected with the power piston 213, when the Stirling generator 21 generates electricity, the heat pipe structure 43 transfers heat energy to the thermal head 22, and pressure fluctuations are generated in the back cavity 23, and the pressure fluctuations drive the power piston 213 to reciprocate, and the phase modulator 212 couples the connecting rod 214 with the power piston 213 through the action of gas to transfer energy. The connecting rods 214 of the two symmetrically arranged Stirling generators 21 are connected by an elastic connector 215. In this embodiment, whether the back cavities 23 of the two symmetrically arranged Stirling generators 21 can effectively couple and eliminate vibration is very important for the power generation of the entire system. In this way, the Stirling generators 21 are symmetrically arranged, and the pressure fluctuations in the back cavities 23 are consistent, so the power piston 213 will automatically move in the opposite direction. In order to ensure that the two power pistons 213 completely move in the opposite direction, the connecting rods 214 of the two symmetrically arranged Stirling generators 21 are connected by elastic connectors 215, so that the moving parts of the two Stirling generators 21 can better offset the vibration. In addition, connecting the back cavities 23 of the two symmetrically arranged Stirling generators 21 can also enhance the coupling of the two symmetrically arranged Stirling generators 21, ensure the reverse movement of the internal moving parts of the two, and achieve a better effect of offsetting vibration. The elastic connector 215 can be selected from a spring or a torsion spring.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
