Description

Technical Field

[0001] The present application relates to the technical field of flow guiding, and particularly relates to a flow guiding assembly, a drainage device and a vehicle for supercritical carbon dioxide. Background Art

[0002] Currently, various waterborne or underwater vehicles need to adjust the overall buoyancy by injecting and draining water into and from water tanks. The existing methods of injecting and draining water mainly include pump-driven drainage and gas-driven drainage.

[0003] Among them, gas-driven drainage uses high-pressure compressible gases for drainage, such as air, nitrogen, carbon dioxide, etc. The principle of using carbon dioxide to undergo a phase change due to heat for drainage has the advantage of a large drainage flow rate compared to air and nitrogen. Carbon dioxide is in a liquid state at a certain pressure and temperature, and can be quickly transformed into a supercritical state by increasing the temperature and pressure. Its volume expands several times, and its instantaneous work capacity is strong, enabling the rapid discharge of water in the water tank.

[0004] However, due to the fast injection speed and high temperature of large-flow supercritical carbon dioxide, it is easily cooled and its temperature is reduced at the initial stage of drainage, increasing its density and thus affecting the expansion drainage capacity. Therefore, it is necessary to improve the drainage efficiency of supercritical carbon dioxide while ensuring the flow rate. Summary of the Invention

[0005] The present application provides a flow guiding assembly, a drainage device and a vehicle for supercritical carbon dioxide. While ensuring a large flow rate of supercritical carbon dioxide, the flow guiding assembly can achieve a good multi-layer deceleration effect on supercritical carbon dioxide, which is beneficial to reducing heat transfer and thus improving the drainage efficiency of supercritical carbon dioxide.

[0006] To achieve the above object, the main technical solutions adopted in the present application include:

[0007] In a first aspect, an embodiment of the present application provides a flow guiding assembly for supercritical carbon dioxide, including:

[0008] A flow guiding structure, the flow guiding structure includes a substrate, a first flow guiding member and a second flow guiding member. Along the thickness direction of the substrate, the substrate has a through first through hole, and along the thickness direction of the substrate, both the first flow guiding member and the second flow guiding member are located on the same side of the substrate;

[0009] The first flow guiding member is fixedly connected to the substrate. Along the circumference of the first through hole, the first flow guiding member is arranged around the first through hole, so that the first flow guiding member and the substrate jointly form an installation space;

[0010] The second flow guide member is fixedly connected to the substrate. Along the circumferential direction of the first flow guide member, the second flow guide member is arranged around the first flow guide member, and along the radial direction of the first flow guide member, the second flow guide member is spaced outside the first flow guide member, so that the first flow guide member, the second flow guide member and the substrate jointly form a first flow guide space;

[0011] A first flow guide portion communicating with both the installation space and the first flow guide space is provided on the outer peripheral wall of the first flow guide member. A second flow guide portion is provided on the outer peripheral wall of the second flow guide member. The second flow guide portion is communicated with the first flow guide portion through the first flow guide space, and at least a part of the second flow guide portion is offset from the first flow guide portion along the axial direction and / or the circumferential direction of the first flow guide member;

[0012] A plugging structure is arranged in the installation space. The plugging structure is used to plug the first through hole and is fixedly connected to the substrate. The plugging structure is configured to open when the external pressure received by the plugging structure is greater than a preset value, so that the first through hole and the installation space are communicated.

[0013] For the flow guide assembly for supercritical carbon dioxide proposed in the first aspect embodiment of the present application, when the pressure of the external large-flow high-pressure supercritical carbon dioxide acting on the plugging structure is greater than the preset value, the plugging structure opens to enable the supercritical carbon dioxide to enter the installation space through the first through hole. The supercritical carbon dioxide entering the installation space flows into the first flow guide space from the first flow guide portion of the first flow guide member. Among them, the first flow guide member can play a certain role in blocking and decelerating the flow of the supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flows out from the second flow guide portion of the second flow guide member. Since at least a part of the second flow guide portion is offset from the first flow guide portion along the axial direction and / or the circumferential direction of the first flow guide member, part of the supercritical carbon dioxide flowing out from the first flow guide portion can be blocked by the second flow guide member, reducing the speed of the supercritical carbon dioxide when flowing out from the second flow guide portion. Thus, while ensuring a large flow of supercritical carbon dioxide, the flow guide assembly can achieve a good multi-layer deceleration effect on the supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide. At the same time, the flow guide assembly is small in volume and high in integration, and is suitable for various narrow spaces.

[0014] Optionally, the first flow guide portion includes a first flow guide layer, and the first flow guide layer includes a plurality of first flow guide holes arranged at intervals along the circumferential direction of the first flow guide member;

[0015] The second flow guide portion includes a second flow guide layer, and the second flow guide layer includes a plurality of second flow guide holes arranged at intervals along the circumferential direction of the second flow guide member. At least a part of the second flow guide layer is offset from the first flow guide layer along the axial direction and / or the circumferential direction of the first flow guide member.

[0016] Since at least part of the second diversion layer is offset from the first diversion layer along the axial direction and / or the circumferential direction of the first diversion member, the multiple first diversion holes of the first diversion layer are not completely opposite to the multiple second diversion holes of the second diversion layer. As a result, part of the supercritical carbon dioxide flowing out of the first diversion holes is blocked by part of the second diversion member and then flows out of the second diversion holes, achieving a good multi-layer deceleration effect and reducing the velocity of the supercritical carbon dioxide when it flows out of the second diversion part.

[0017] Optionally, there are multiple first diversion layers, and the multiple first diversion layers are arranged at intervals along the axial direction of the first diversion member;

[0018] There are multiple second diversion layers, and the multiple second diversion layers are arranged at intervals along the axial direction of the second diversion member. Along the axial direction and / or the circumferential direction of the first diversion member, at least part of at least some of the second diversion layers among the multiple second diversion layers is offset from the corresponding first diversion layer.

[0019] Since the multiple first diversion holes of the multiple first diversion layers are not completely opposite to the multiple second diversion holes of the multiple second diversion layers, part of the supercritical carbon dioxide flowing out of the first diversion holes is blocked by part of the second diversion member and then flows out of the second diversion holes, achieving a good multi-layer deceleration effect. Moreover, the setting of multiple second diversion layers is also beneficial to further reducing the velocity of the supercritical carbon dioxide when it flows out of the second diversion part.

[0020] Optionally, there are multiple second diversion members. Along the radial direction of the first diversion member, the multiple second diversion members are arranged at intervals in sequence. Adjacent two second diversion members and the substrate jointly form a second diversion space, and the second diversion parts of adjacent two second diversion members are communicated through the second diversion space.

[0021] Thus, by setting multiple second diversion members, it is possible to further block and decelerate the flow of supercritical carbon dioxide, further improving the multi-layer deceleration effect of the diversion structure, and thus being beneficial to further reducing the velocity of the supercritical carbon dioxide when it flows out of the second diversion part.

[0022] Optionally, along the axial direction and / or the circumferential direction of the first diversion member, at least part of the second diversion part of the outer second diversion member among adjacent two second diversion members is offset from the second diversion part of the inner second diversion member.

[0023] Since the multiple second diversion holes of the multiple second diversion layers in the outer second diversion member are not completely opposite to the multiple second diversion holes of the multiple second diversion layers in the inner second diversion member, part of the supercritical carbon dioxide flowing out of the second diversion holes in the inner second diversion member is blocked by part of the inner second diversion member and then flows out of the second diversion holes of the outer second diversion member. The second diversion holes arranged with an offset between the inner and outer sides further improve the multi-layer deceleration effect of the diversion structure, and thus are beneficial to further reducing the velocity of the supercritical carbon dioxide when it flows out of the second diversion part.

[0024] Optionally, the plugging structure includes a plugging member and a fixing member. The plugging member is used to plug the first through hole, and the fixing member is used to fixedly connect the plugging member and the substrate. The fixing member is configured to break when the external pressure on the plugging member is greater than the preset breaking force of the fixing member, so as to open the plugging member.

[0025] If the fixing member breaks when the external pressure on the plugging member is greater than the preset breaking force of the fixing member, the plugging member opens under the impact of supercritical carbon dioxide, meeting the requirements of the plugging structure, and the structure is simple and reliable, and the cost is low.

[0026] Optionally, it further includes: a guiding member fixedly arranged in the installation space. The guiding member has a guiding hole extending along the axial direction of the first guiding member. The plugging member has a guiding rod corresponding to the guiding hole. The guiding rod passes through the guiding hole and is movable relative to the guiding hole.

[0027] Along the thickness direction of the guiding member, the guiding member has a through second through hole.

[0028] With such a setting, under the guiding cooperation of the guiding rod and the guiding hole, it is beneficial to improve the stability of the movement of the plugging member, and the guiding member can block part of the supercritical carbon dioxide flowing out of the first sub-space, so as to be beneficial to reducing the speed of the supercritical carbon dioxide flowing out of the open end of the installation space, and is beneficial to further improving the drainage efficiency of the supercritical carbon dioxide.

[0029] Optionally, it further includes: a cover plate fixedly arranged in the installation space. The cover plate is located on the side of the guiding member away from the substrate and is spaced apart from the guiding member. The cover plate is used to cover the open end of the installation space. Along the thickness direction of the cover plate, the cover plate has a through third through hole, so that the installation space communicates with the outside through the third through hole.

[0030] With such a setting, when part of the supercritical carbon dioxide sequentially passes through the fourth through hole and the second through hole from the first sub-space and enters the second sub-space, the supercritical carbon dioxide in the second sub-space sprays outwards through the third through hole of the cover plate, so as to further reduce the speed of the supercritical carbon dioxide flowing out of the open end of the installation space.

[0031] In a second aspect, an embodiment of the present application provides a drainage device, including the guiding component in the first aspect embodiment.

[0032] The drainage device proposed in the second aspect embodiment of the present application, by providing the above-mentioned guiding component, while ensuring a large flow of supercritical carbon dioxide, can achieve a good multi-layer deceleration effect on the supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide, and further improving the drainage efficiency of the drainage device.

[0033] In a third aspect, an embodiment of the present application provides a vehicle, including the drainage device in the embodiment of the second aspect.

[0034] The vehicle proposed in the third aspect embodiment of the present application is provided with the above drainage device. The diversion component of the drainage device can ensure a large flow of supercritical carbon dioxide while achieving a good multi-layer deceleration effect on supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of supercritical carbon dioxide and further enhancing the buoyancy adjustment efficiency of the vehicle.

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

The phrase appears in various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those of ordinary skill in the art explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0054] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "attached" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0055] In this application, the term "and / or" is merely a description of the relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, both A and B exist simultaneously, and B exists alone.

[0056] In this application, "multiple" means two or more (including two). Similarly, "multiple groups" means two or more groups (including two groups), and "multiple pieces" means two or more pieces (including two pieces).

[0057] Currently, various waterborne or underwater vehicles need to adjust their overall buoyancy by filling and draining water tanks. The existing filling and draining methods are mainly pump-driven drainage and gas-driven drainage.

[0058] Among them, gas-driven drainage uses high-pressure compressible gases for drainage, such as air, nitrogen, carbon dioxide, etc. The principle of using carbon dioxide to undergo a phase change when heated for drainage has the advantage of a larger drainage flow rate compared to air and nitrogen. Carbon dioxide is in a liquid state at a certain pressure and temperature. By increasing the temperature and pressure, it can quickly transform into a supercritical state, with its volume expanding several times and its instantaneous work capacity being strong, enabling the rapid drainage of water in the water tank.

[0059] However, due to the fast injection speed and high temperature of large-flow supercritical carbon dioxide, it is easily cooled and its temperature is reduced at the initial stage of drainage, causing its density to increase, thereby affecting the expansion drainage capacity. Therefore, it is necessary to improve the drainage efficiency of supercritical carbon dioxide while ensuring the flow rate.

[0060] In related technologies, usually, the method of increasing the diameter of the pipeline providing supercritical carbon dioxide or using a gas diffuser is adopted to reduce the ejection speed of supercritical carbon dioxide. However, the above methods have disadvantages such as large space volume occupation and complex structure, and are difficult to be used in places with limited space.

[0061] Based on this, the present application proposes a diversion component 100 for supercritical carbon dioxide. When the pressure of the external large-flow high-pressure supercritical carbon dioxide acting on the plugging structure 2 is greater than a preset value, the plugging structure 2 opens to allow the supercritical carbon dioxide to enter the installation space 14 through the first through hole 111. The supercritical carbon dioxide entering the installation space 14 flows into the first diversion space 15 from the first diversion part 121 of the first diversion member 12. Among them, the first diversion member 12 can play a certain role in blocking and decelerating the flow of the supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flows out from the second diversion part 131 of the second diversion member 13. Since at least a part of the second diversion part 131 is offset from the first diversion part 121 along the axial direction and / or the circumferential direction of the first diversion member 12, part of the supercritical carbon dioxide flowing out from the first diversion part 121 can be blocked by the second diversion member 13, thereby further reducing the velocity of the supercritical carbon dioxide when flowing out from the second diversion part 131. Thus, while ensuring a large flow of supercritical carbon dioxide, the diversion component 100 can achieve a good multi-layer deceleration effect on the supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide. At the same time, the diversion component 100 is small in volume and high in integration, and is suitable for various narrow spaces.

[0062] Next, the diversion component 100, the drainage device 1000, and the vehicle proposed in the embodiments of the present application will be described with reference to the accompanying drawings.

[0063] As Figures 1-6 shown, the diversion component 100 according to the first aspect embodiment of the present application includes: a diversion structure 1 and a plugging structure 2.

[0064] Among them, the diversion structure 1 includes a substrate 11, a first diversion member 12, and a second diversion member 13. Along the thickness direction of the substrate 11, the substrate 11 has a through first through hole 111, and along the thickness direction of the substrate 11, both the first diversion member 12 and the second diversion member 13 are located on the same side of the substrate 11, that is, the first diversion member 12 and the second diversion member 13 are provided on the same end face of the substrate 11.

[0065] Furthermore, the first diversion member 12 is fixedly connected to the substrate 11. Along the circumferential direction of the first through hole 111, the first diversion member 12 is arranged around the first through hole 111 so that the first diversion member 12 and the substrate 11 jointly form an installation space 14.

[0066] Specifically, one end of the first flow guide member 12 is fixedly connected to the substrate 11, and the other end extends away from the substrate 11 in the thickness direction of the substrate 11. The first flow guide member 12 can be configured as an annular structure. The first flow guide member 12 is disposed around the first through hole 111 along the circumferential direction of the first through hole 111. It can be understood that, along the radial direction of the first through hole 111, the first flow guide member 12 is spaced apart from the first through hole 111. In this way, the first flow guide member 12 and the substrate 11 jointly form a cylindrical installation space 14, where one end of the installation space 14 away from the substrate 11 is an open end.

[0067] Further, the second flow guide member 13 is fixedly connected to the substrate 11. Along the circumferential direction of the first flow guide member 12, the second flow guide member 13 is disposed around the first flow guide member 12, and along the radial direction of the first flow guide member 12, the second flow guide member 13 is spaced apart and disposed outside the first flow guide member 12, so that the first flow guide member 12, the second flow guide member 13, and the substrate 11 jointly form a first flow guide space 15.

[0068] Specifically, one end of the second flow guide member 13 is fixedly connected to the substrate 11, and the other end extends away from the substrate 11 in the thickness direction of the substrate 11. The second flow guide member 13 can also be configured as an annular structure. The second flow guide member 13 is disposed around the first flow guide member 12 along the circumferential direction of the first flow guide member 12, and along the radial direction of the first flow guide member 12, as Figure 2 shown, the second flow guide member 13 is spaced apart from the first flow guide member 12, and the second flow guide member 13 is disposed outside the first flow guide member 12. In this way, the first flow guide member 12, the second flow guide member 13, and the substrate 11 jointly form an annular first flow guide space 15, where one end of the first flow guide space 15 away from the substrate 11 is an open end.

[0069] Further, a first flow guide portion 121 communicating with both the installation space 14 and the first flow guide space 15 is provided on the outer peripheral wall of the first flow guide member 12. A second flow guide portion 131 is provided on the outer peripheral wall of the second flow guide member 13. The second flow guide portion 131 is communicated with the first flow guide portion 121 through the first flow guide space 15. Optionally, a flow blocking portion can be provided in the first flow guide space 15. For example, by adding micro flow guide fins or honeycomb structures on the outer peripheral wall of the first flow guide member 12 and / or the inner peripheral wall of the second flow guide member 13 to guide the supercritical carbon dioxide to form a laminar flow. In this way, it is beneficial to reduce the temperature rise caused by turbulence, thereby being beneficial to reducing heat exchange and further improving the stability of the supercritical carbon dioxide.

[0070] Further, at least a part of the second flow guide portion 131 is offset from the first flow guide portion 121 along the axial direction and / or the circumferential direction of the first flow guide member 12.

[0071] For example, taking the flow guide assembly 100 in accordance with Figure 2Taking the shown placement direction as an example for illustration, the axial direction of the first flow guiding member 12 is the height direction of the flow guiding assembly 100. That is, in the height direction of the flow guiding assembly 100, at least part of the second flow guiding portion 131 is offset from the first flow guiding portion 121. It can be understood that part of the second flow guiding portion 131 can be offset vertically from the first flow guiding portion 121. Further, the second flow guiding portion 131 can also be completely offset vertically from the first flow guiding portion 121, which is specifically set according to the actual situation and is not specifically limited herein.

[0072] Alternatively, along the circumferential direction of the first flow guiding member 12, at least part of the second flow guiding portion 131 is offset from the first flow guiding portion 121. For example, continuing to take the flow guiding assembly 100 arranged in the Figure 2 shown placement direction as an example for illustration, the second flow guiding portion 131 of the second flow guiding member 13 is arranged around the first flow guiding member 12 along the circumferential direction of the first flow guiding member 12. Among them, part of the second flow guiding portion 131 can be offset circumferentially from the first flow guiding portion 121. Further, the second flow guiding portion 131 can also be completely offset circumferentially from the first flow guiding portion 121, which is specifically set according to the actual situation and is not specifically limited herein.

[0073] Alternatively, along the axial and circumferential directions of the first flow guiding member 12, at least part of the second flow guiding portion 131 is offset from the first flow guiding portion 121. For example, continuing to take the flow guiding assembly 100 arranged in the Figure 2 shown placement direction as an example for illustration, that is, in the height direction of the flow guiding assembly 100 and along the circumferential direction of the first flow guiding member 12, part of the second flow guiding portion 131 can be offset from the first flow guiding portion 121. Further, the second flow guiding portion 131 can also be completely offset from the first flow guiding portion 121, which is specifically set according to the actual situation and is not specifically limited herein. With such a setting, it is ensured that the first flow guiding portion 121 on the first flow guiding member 12 and the second flow guiding portion 131 on the second flow guiding member 13 are not completely opposite.

[0074] Further, the blocking structure 2 is arranged in the installation space 14. The blocking structure 2 is used to block the first through hole 111 and is fixedly connected to the substrate 11. The blocking structure 2 is configured to open when the external pressure received by the blocking structure 2 is greater than a preset value, so that the first through hole 111 and the installation space 14 are communicated. That is to say, the blocking structure 2 is fixedly connected to the substrate 11 and arranged in the installation space 14, and the blocking structure 2 is used to block the first through hole 111. When the external pressure received by the blocking structure 2 is greater than a preset value, it opens, so that the first through hole 111 and the installation space 14 are communicated.

[0075] Further, to enable those skilled in the art to better understand the present application, as Figure 1 shown, the present application takes the flow guiding assembly 100 being used in the drainage device 1000 as an example for illustration.

[0076] Specifically, Figure 1 As shown, the drainage device 1000 includes a power unit 200, and the power unit 200 has a storage chamber. The present application takes the storage of liquid carbon dioxide in the storage chamber as an example for explanation. Further, the power unit 200 is fixedly connected to the guide assembly 100 through a connecting pipe 300. Specifically, the connecting pipe 300 is fixedly connected to the substrate 11 of the guide structure 1 and is located on the side of the substrate 11 away from the first guide member 12 and the second guide member 13, wherein the connecting pipe 300 is communicated with the first through hole 111. Under certain specific conditions, when the liquid carbon dioxide in the storage chamber is converted into supercritical carbon dioxide, The supercritical carbon dioxide is transported to the first through hole 111 of the guide structure 1 along the connecting pipe 300. The supercritical carbon dioxide in the first through hole 111 applies external pressure to the blocking structure 2 blocked in the first through hole 111. If the external pressure on the blocking structure 2 is greater than the preset value, the blocking structure 2 is opened. It can be understood that since the blocking structure 2 is fixedly connected to the substrate 11, the preset value can be constructed as the maximum force required when the blocking structure 2 is separated from the substrate 11. When the blocking structure 2 is opened, a large flow of high-pressure supercritical carbon dioxide in the connecting pipe 300 enters the installation space 14 from the first through hole 111. , wherein part of the supercritical carbon dioxide is ejected from the open end of the installation space 14, and part of the supercritical carbon dioxide flows into the first guide space 15 from the first guide portion 121 of the first guide member 12, wherein the first guide member 12 can play a certain blocking and decelerating role on the flow of supercritical carbon dioxide, and then the supercritical carbon dioxide that flows into the first guide space 15 is ejected from the open end of the first guide space 15, and another part of the supercritical carbon dioxide that flows into the first guide space 15 flows out from the second guide portion 131 of the second guide member 13. Due to the axial and / or circumferential direction of the first guide member 12, the first guide member 12 is provided with a plurality of supercritical carbon dioxide particles, and the supercritical carbon dioxide particles are ... At least part of the second guide part 131 is offset from the first guide part 121, so that part of the supercritical carbon dioxide flowing out of the first guide part 121 can be blocked by the second guide part 13, thereby reducing the speed of the supercritical carbon dioxide flowing out of the second guide part 131. In this way, the guide component 100 can ensure a large flow of supercritical carbon dioxide while arranging the relatively offset first guide part 121 and second guide part 131 to achieve a good multi-layer deceleration effect on the supercritical carbon dioxide flowing into the guide structure 1, which is beneficial to reduce heat transfer and thus improve the drainage efficiency of the supercritical carbon dioxide.

[0077] It should be noted that the flow guide assembly 100 in the present application is relatively simple and small in size, meets the injection requirements of a large flow of high-pressure supercritical carbon dioxide, and has a high degree of integration, and is suitable for various narrow spaces.

[0078] In summary, the flow guiding assembly 100 for supercritical carbon dioxide according to the embodiments of the first aspect of the present application can achieve a good multi-layer deceleration effect on supercritical carbon dioxide while ensuring a large flow rate of supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of supercritical carbon dioxide. At the same time, the flow guiding assembly 100 is small in volume and high in integration, and is suitable for various narrow spaces.

[0079] In some embodiments of the present application, as Figure 3 and Figure 4 shown, the first flow guiding portion 121 includes a first flow guiding layer 1211, the first flow guiding layer 1211 includes a plurality of first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12, the second flow guiding portion 131 includes a second flow guiding layer 1311, the second flow guiding layer 1311 includes a plurality of second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13, and at least a part of the second flow guiding layer 1311 is offset from the first flow guiding layer 1211 along the axial direction and / or the circumferential direction of the first flow guiding member 12.

[0080] Specifically, the first flow guiding portion 121 can be configured as the first flow guiding layer 1211 composed of a plurality of first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12, and the second flow guiding portion 131 can be configured as the second flow guiding layer 1311 composed of a plurality of second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13, wherein at least a part of the second flow guiding layer 1311 is offset from the first flow guiding layer 1211 along the axial direction and / or the circumferential direction of the first flow guiding member 12.

[0081] That is to say, along the axial direction of the first flow guiding member 12, at least a part of the second flow guiding layer 1311 is offset from the first flow guiding layer 1211. Taking the placement direction shown in Figure 4 as an example, assuming that the first flow guiding layer 1211 includes 8 first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12, and the second flow guiding layer 1311 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13. For example, 4 of the 8 second flow guiding holes 13111 can be partially offset up and down from some of the 8 first flow guiding holes 12111 in the height direction of the flow guiding assembly 100, 4 of the 8 second flow guiding holes 13111 are all offset up and down from the 8 first flow guiding holes 12111 in the height direction of the flow guiding assembly 100, or all 8 second flow guiding holes 13111 are offset up and down from the 8 first flow guiding holes 12111 in the height direction of the flow guiding assembly 100, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0082] Alternatively, along the circumferential direction of the first flow guide member 12, at least a partial region of the second flow guide layer 1311 is offset from the first flow guide layer 1211. Continuing to take the placement direction of the flow guide assembly 100 shown in Figure 4 as an example for illustration. For example, eight second flow guide holes 13111 of the second flow guide layer 1311 are arranged around the first flow guide layer 1211 along the circumferential direction of the first flow guide layer 1211. Among them, four of the eight second flow guide holes 13111 may be partially circumferentially offset from some of the first flow guide holes 12111 of the eight first flow guide holes 12111, or four of the eight second flow guide holes 13111 may be circumferentially offset from all of the eight first flow guide holes 12111, or the eight second flow guide holes 13111 may be completely circumferentially offset from the eight first flow guide holes 12111. It is specifically set according to the actual situation, and no further examples will be given here;

[0083] Alternatively, along the axial and circumferential directions of the first flow guide member 12, at least a partial region of the second flow guide layer 1311 is offset from the first flow guide layer 1211. Continuing to take the placement direction of the flow guide assembly 100 shown in Figure 4 as an example for illustration. For example, in the height direction of the flow guide assembly 100 and along the circumferential direction of the first flow guide member 12, four of the eight second flow guide holes 13111 may be partially offset from some of the first flow guide holes 12111 of the eight first flow guide holes 12111, or four of the eight second flow guide holes 13111 may be offset from all of the eight first flow guide holes 12111, or the eight second flow guide holes 13111 may be completely offset from the eight first flow guide holes 12111. It is specifically set according to the actual situation, and no further examples will be given here. With such a setting, it is ensured that the multiple first flow guide holes 12111 of the first flow guide layer 1211 and the multiple second flow guide holes 13111 of the second flow guide layer 1311 are not completely opposite.

[0084] Further, as a specific example, when supercritical carbon dioxide enters the installation space 14 through the first through-hole 111, part of the supercritical carbon dioxide flows into the first diversion space 15 from the plurality of first diversion holes 12111. Since the plurality of first diversion holes 12111 are circumferentially spaced along the first diversion member 12, the first diversion member 12 can play a certain role in blocking and decelerating the flow of supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flowing into the first diversion space 15 flows out from the plurality of second diversion holes 13111 of the second diversion member 13. Since the plurality of first diversion holes 12111 of the first diversion layer 1211 and the plurality of second diversion holes 13111 of the second diversion layer 1311 are not completely opposite, part of the supercritical carbon dioxide flowing out from the first diversion holes 12111 is blocked by part of the second diversion member 13 and then flows out from the second diversion holes 13111, achieving a good multi-layer deceleration effect and reducing the velocity of the supercritical carbon dioxide when it flows out from the second diversion part 131.

[0085] In some embodiments of the present application, along the radial direction of the first diversion member 12, the diversion holes can be designed with gradient apertures. For example, the size of the first diversion hole 12111 is greater than or equal to the size of the second diversion hole 13111. In this way, combined with the staggered distribution of the first diversion hole 12111 and the second diversion hole 13111, a step-by-step pressure boosting effect can be formed, which can reduce the energy loss caused by turbulence while reducing the injection velocity of supercritical carbon dioxide.

[0086] In some embodiments of the present application, a convex structure or a grid structure can be provided in the first diversion hole 12111 and the second diversion hole 13111, which can reduce the velocity of the supercritical carbon dioxide flowing out from the first diversion hole 12111 and the second diversion hole 13111, and thus is beneficial to further reducing heat transfer and improving drainage efficiency.

[0087] In some embodiments of the present application, as Figure 3 and Figure 4 shown, there are multiple first diversion layers 1211, and the multiple first diversion layers 1211 are axially spaced along the first diversion member 12. There are multiple second diversion layers 1311, and the multiple second diversion layers 1311 are axially spaced along the second diversion member 13. Along the axial direction and / or circumferential direction of the first diversion member 12, at least part of the at least part of the second diversion layers 1311 in the multiple second diversion layers 1311 are staggered from the corresponding first diversion layers 1211.

[0088] Specifically, the first flow guiding part 121 can be configured to be composed of a plurality of first flow guiding layers 1211 arranged at intervals along the axial direction of the first flow guiding member 12. Among them, the first flow guiding layer 1211 includes a plurality of first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12. The second flow guiding part 131 can be configured to be composed of a plurality of second flow guiding layers 1311 arranged at intervals along the axial direction of the second flow guiding member 13. The second flow guiding layer 1311 includes a plurality of second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13. Further, along the axial direction and / or the circumferential direction of the first flow guiding member 12, at least some regions of at least some of the plurality of second flow guiding layers 1311 are offset from the corresponding first flow guiding layers 1211.

[0089] That is to say, along the axial direction of the first flow guiding member 12, at least some regions of at least some of the plurality of second flow guiding layers 1311 are offset from the corresponding first flow guiding layers 1211. Continuing to take the flow guiding assembly 100 as an example in the Figure 4 shown placement direction for illustration. Suppose the first flow guiding part 121 includes 2 first flow guiding layers 1211, and each first flow guiding layer 1211 includes 8 first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12. The second flow guiding part 131 includes 6 second flow guiding layers 1311, and each second flow guiding layer 1311 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13. For example, among the 6 second flow guiding layers 1311, 4 of the 8 second flow guiding holes 13111 in one of the second flow guiding layers 1311 can be partially offset up and down from the 8 first flow guiding holes 12111 in any one of the first flow guiding layers 1211 in the height direction of the flow guiding assembly 100, or the 6 second flow guiding layers 1311 are offset up and down from the 2 first flow guiding layers 1211 in the height direction of the flow guiding assembly 100, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0090] Or, along the circumferential direction of the first flow guiding member 12, at least some regions of at least some of the plurality of second flow guiding layers 1311 are offset from the corresponding first flow guiding layers 1211. Continuing to take the flow guiding assembly 100 as an example in the Figure 4Taking the shown placement direction as an example for illustration, assume that the first flow guiding part 121 includes 2 first flow guiding layers 1211, and each first flow guiding layer 1211 includes 8 first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12. The second flow guiding part 131 includes 6 second flow guiding layers 1311, and each second flow guiding layer 1311 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13. For example, among the 6 second flow guiding layers 1311, 4 of the 8 second flow guiding holes 13111 in one of the second flow guiding layers 1311 can be partially circumferentially offset from the 8 first flow guiding holes 12111 in any one of the first flow guiding layers 1211, or each of the second flow guiding holes 13111 in the 6 second flow guiding layers 1311 can be completely circumferentially offset from the first flow guiding holes 12111 in 2 first flow guiding layers 1211, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0091] Or, along the axial and circumferential directions of the first flow guiding member 12, at least some regions of at least some of the second flow guiding layers 1311 among the multiple second flow guiding layers 1311 are offset from the corresponding first flow guiding layers 1211. Continuing to take the flow guiding assembly 100 in the Figure 4 shown placement direction as an example for illustration, assume that the first flow guiding part 121 includes 2 first flow guiding layers 1211, and each first flow guiding layer 1211 includes 8 first flow guiding holes 12111 arranged at intervals along the circumferential direction of the first flow guiding member 12. The second flow guiding part 131 includes 6 second flow guiding layers 1311, and each second flow guiding layer 1311 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the second flow guiding member 13. For example, in the height direction of the flow guiding assembly 100 and along the circumferential direction of the first flow guiding member 12, among the 6 second flow guiding layers 1311, 4 of the 8 second flow guiding holes 13111 in one of the second flow guiding layers 1311 can be partially offset from the 8 first flow guiding holes 12111 in any one of the first flow guiding layers 1211, or each of the second flow guiding holes 13111 in the 6 second flow guiding layers 1311 can be completely offset from the first flow guiding holes 12111 in 2 first flow guiding layers 1211, which is specifically set according to the actual situation and will not be exemplified one by one here. With such a setting, it is ensured that the multiple first flow guiding holes 12111 of the multiple first flow guiding layers 1211 and the multiple second flow guiding holes 13111 of the multiple second flow guiding layers 1311 are not completely opposite.

[0092] Further, as a specific example, when supercritical carbon dioxide enters the installation space 14 through the first through-hole 111, part of the supercritical carbon dioxide flows into the first diversion space 15 from the first diversion holes 12111 in the multiple first diversion layers 1211. While meeting the injection requirements, it is beneficial to further reduce the outflow velocity of the supercritical carbon dioxide from the first diversion member 12, improving the blocking and decelerating effect of the first diversion member 12 on the supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flowing into the first diversion space 15 flows out from the second diversion holes 13111 in the multiple second diversion layers 1311. Since the multiple first diversion holes 12111 in the multiple first diversion layers 1211 are not completely opposite to the multiple second diversion holes 13111 in the multiple second diversion layers 1311, part of the supercritical carbon dioxide flowing out from the first diversion holes 12111 is blocked by part of the second diversion member 13 and then flows out from the second diversion holes 13111, achieving a good multi-layer deceleration effect. Moreover, the setting of the multiple second diversion layers 1311 is also beneficial to further reduce the velocity of the supercritical carbon dioxide when it flows out from the second diversion part 131.

[0093] In some embodiments of the present application, as Figures 2-5 shown, there are multiple second diversion members 13. Along the radial direction of the first diversion member 12, the multiple second diversion members 13 are sequentially arranged at intervals. A second diversion space 16 is jointly formed by two adjacent second diversion members 13 and the substrate 11, and the second diversion parts 131 of two adjacent second diversion members 13 are communicated through the second diversion space 16.

[0094] Specifically, the diversion structure 1 can be provided with multiple second diversion members 13 in a ring structure. Among them, along the radial direction of the first diversion member 12, each second diversion member 13 is arranged at intervals outside the first diversion member 12, and the multiple second diversion members 13 are sequentially arranged at intervals. In this way, a ring-shaped second diversion space 16 is jointly formed by two adjacent second diversion members 13 and the substrate 11. Further, the second diversion parts 131 of two adjacent second diversion members 13 are communicated through the second diversion space 16 formed by the two adjacent second diversion members 13. Optionally, a flow blocking part can be arranged in the second diversion space 16. For example, by adding micro diversion fins and honeycomb structures in the second diversion space 16 to guide the supercritical carbon dioxide to form a laminar flow, this is beneficial to reducing the temperature rise caused by turbulence, thus being beneficial to reducing heat exchange and further enhancing the stability of the supercritical carbon dioxide.

[0095] For example, referring to Figure 3As shown, there are two second flow guiding members 13 provided on the outer side of the first flow guiding member 12. Among them, the inner second flow guiding member 13 and the first flow guiding member 12 form a first flow guiding space 15, and a second flow guiding space 16 is formed between the outer second flow guiding member 13 and the inner second flow guiding member 13. The second flow guiding portion 131 of the inner second flow guiding member 13 communicates with the second flow guiding portion 131 of the outer second flow guiding member 13 through the second flow guiding space 16. When supercritical carbon dioxide enters the installation space 14 through the first through hole 111, part of the supercritical carbon dioxide sequentially flows from the installation space 14 into the first flow guiding space 15 and the second flow guiding space 16, and then sprays out from the second flow guiding portion 131 of the outer second flow guiding member 13.

[0096] It can be understood that if there are three second flow guiding members 13 provided on the outer side of the first flow guiding member 12, then the three second flow guiding members 13 form two second flow guiding spaces 16. When supercritical carbon dioxide enters the installation space 14 through the first through hole 111, the supercritical carbon dioxide flows from the installation space 14 into the first flow guiding space 15, and then sequentially passes through the two second flow guiding spaces 16 from the first flow guiding space 15 and sprays out from the second flow guiding portion 131 of the outermost second flow guiding member 13. Thus, by providing a plurality of second flow guiding members 13, the flow of supercritical carbon dioxide can be further blocked and decelerated, further improving the multi-layer deceleration effect of the flow guiding structure 1, which is beneficial to further reducing the speed of the supercritical carbon dioxide when flowing out from the second flow guiding portion 131.

[0097] In some embodiments of the present application, as Figures 3-5 shown, along the axial direction and / or circumferential direction of the first flow guiding member 12, at least a part of the second flow guiding portion 131 of the outer second flow guiding member 13 among two adjacent second flow guiding members 13 is offset from the second flow guiding portion 131 of the inner second flow guiding member 13.

[0098] Specifically, when a plurality of second flow guiding members 13 are provided on the outer side of the first flow guiding member 12, along the axial direction and / or circumferential direction of the first flow guiding member 12, at least a part of the second flow guiding portion 131 of the outer second flow guiding member 13 among two adjacent second flow guiding members 13 is offset from the second flow guiding portion 131 of the inner second flow guiding member 13.

[0099] For example, assume that there are two second flow guiding members 13 provided on the outer side of the first flow guiding member 12. Along the axial direction and / or circumferential direction of the first flow guiding member 12, at least a part of the second flow guiding portion 131 of the outer second flow guiding member 13 is offset from the second flow guiding portion 131 of the inner second flow guiding member 13. That is to say, along the axial direction of the first flow guiding member 12, at least a part of the second flow guiding portion 131 of the outer second flow guiding member 13 is offset from the second flow guiding portion 131 of the inner second flow guiding member 13. For example, taking the flow guiding assembly 100 in accordance with Figure 4Taking the shown placement direction as an example for illustration, the axial direction of the first flow guide member 12 is the height direction of the flow guide assembly 100. That is, in the height direction of the flow guide assembly 100, at least part of the second flow guide portion 131 of the outer second flow guide member 13 is offset from the second flow guide portion 131 of the inner second flow guide member 13. It can be understood that part of the second flow guide portion 131 of the outer second flow guide member 13 and the second flow guide portion 131 of the inner second flow guide member 13 can be partially offset vertically. Further, the second flow guide portion 131 of the outer second flow guide member 13 can also be completely offset vertically from the second flow guide portion 131 of the inner second flow guide member 13, which is specifically set according to the actual situation and is not specifically limited here;

[0100] Or, along the circumferential direction of the first flow guide member 12, at least part of the second flow guide portion 131 of the outer second flow guide member 13 is offset from the second flow guide portion 131 of the inner second flow guide member 13. For example, continuing to take the flow guide assembly 100 in the Figure 4 shown placement direction as an example for illustration, the second flow guide portion 131 of the outer second flow guide member 13 is arranged around the circumferential direction of the inner second flow guide member 13. Among them, part of the second flow guide portion 131 of the outer second flow guide member 13 and the second flow guide portion 131 of the inner second flow guide member 13 can be partially offset circumferentially. Further, the second flow guide portion 131 of the outer second flow guide member 13 can also be completely offset circumferentially from the second flow guide portion 131 of the inner second flow guide member 13, which is specifically set according to the actual situation and is not specifically limited here;

[0101] Or, along the axial direction and the circumferential direction of the first flow guide member 12, at least part of the second flow guide portion 131 of the outer second flow guide member 13 is offset from the second flow guide portion 131 of the inner second flow guide member 13. For example, continuing to take the flow guide assembly 100 in the Figure 4 shown placement direction as an example for illustration, that is, in the height direction of the flow guide assembly 100 and along the circumferential direction of the first flow guide member 12, part of the second flow guide portion 131 of the outer second flow guide member 13 and the second flow guide portion 131 of the inner second flow guide member 13 can be partially offset. Further, the second flow guide portion 131 of the outer second flow guide member 13 can also be completely offset from the second flow guide portion 131 of the inner second flow guide member 13, which is specifically set according to the actual situation and is not specifically limited here.

[0102] Further, as a specific example, the second guiding portions 131 of the outer second guiding member 13 and the second guiding portions 131 of the inner second guiding member 13 both include a plurality of second guiding layers 1311. Among them, the plurality of second guiding layers 1311 of the outer second guiding member 13 are arranged at intervals along the axial direction of the outer second guiding member 13, and the plurality of second guiding layers 1311 of the inner second guiding member 13 are arranged at intervals along the axial direction of the inner second guiding member 13. The outer second guiding layer 1311 includes a plurality of second guiding holes 13111 arranged at intervals along the circumferential direction of the outer second guiding member 13, and the inner second guiding layer 1311 includes a plurality of second guiding holes 13111 arranged at intervals along the circumferential direction of the inner second guiding member 13. Along the axial direction and / or circumferential direction of the first guiding member 12, at least a part of the regions of at least some of the plurality of second guiding layers 1311 of the outer second guiding member 13 are staggered from the corresponding second guiding layers 1311 of the inner second guiding member 13.

[0103] That is to say, along the axial direction of the first guiding member 12, at least a part of the regions of at least some of the plurality of second guiding layers 1311 of the outer second guiding member 13 are staggered from the corresponding second guiding layers 1311 of the inner second guiding member 13. Continuing to take the guiding component 100 as an example according to the Figure 4 placement direction shown, assuming that the outer second guiding member 13 includes 6 second guiding layers 1311, each second guiding layer 1311 of the outer second guiding member 13 includes 8 second guiding holes 13111 arranged at intervals along the circumferential direction of the outer second guiding member 13, the inner second guiding member 13 includes 6 second guiding layers 1311, and each second guiding layer 1311 of the inner second guiding member 13 includes 8 second guiding holes 13111 arranged at intervals along the circumferential direction of the inner second guiding member 13. For example, among the 6 second guiding layers 1311 of the outer second guiding member 13, 4 of the 8 second guiding holes 13111 in 1 of the second guiding layers 1311 can be partially staggered up and down in the height direction of the guiding component 100 from the 8 second guiding holes 13111 in any one of the second guiding layers 1311 of the inner second guiding member 13, or the 6 second guiding layers 1311 in the outer second guiding member 13 are sequentially staggered up and down at intervals in the height direction of the guiding component 100 from the 6 second guiding layers 1311 in the inner second guiding member 13, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0104] Or, along the circumferential direction of the first guiding member 12, at least a part of the regions of at least some of the plurality of second guiding layers 1311 of the outer second guiding member 13 are staggered from the corresponding second guiding layers 1311 of the inner second guiding member 13. Continuing to take the guiding component 100 as an example according to theFigure 4 Taking the shown placement direction as an example for illustration, assume that the outer second flow guiding member 13 includes 6 second flow guiding layers 1311. Each second flow guiding layer 1311 of the outer second flow guiding member 13 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the outer second flow guiding member 13. The inner second flow guiding member 13 includes 6 second flow guiding layers 1311. Each second flow guiding layer 1311 of the inner second flow guiding member 13 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the inner second flow guiding member 13. For example, among the 6 second flow guiding layers 1311 of the outer second flow guiding member 13, 4 of the 8 second flow guiding holes 13111 in one of the second flow guiding layers 1311 can be partially circumferentially offset from the second flow guiding holes 13111 in any one of the 8 second flow guiding holes 13111 in the second flow guiding layer 1311 of the inner second flow guiding member 13. Or, the second flow guiding holes 13111 in the 6 second flow guiding layers 1311 of the outer second flow guiding member 13 are all circumferentially offset from the second flow guiding holes 13111 in the 6 second flow guiding layers 1311 of the inner second flow guiding member 13, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0105] Or, along the axial and circumferential directions of the first flow guiding member 12, at least some regions of at least some of the second flow guiding layers 1311 of the outer second flow guiding member 13 are offset from the corresponding second flow guiding layers 1311 of the inner second flow guiding member 13. Continuing with the flow guiding assembly 100 in accordance with Figure 4Taking the shown placement direction as an example for illustration, assume that the outer second flow guiding member 13 includes 6 second flow guiding layers 1311. Each second flow guiding layer 1311 of the outer second flow guiding member 13 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the outer second flow guiding member 13. The inner second flow guiding member 13 includes 6 second flow guiding layers 1311. Each second flow guiding layer 1311 of the inner second flow guiding member 13 includes 8 second flow guiding holes 13111 arranged at intervals along the circumferential direction of the inner second flow guiding member 13. For example, in the height direction of the flow guiding assembly 100 and along the circumferential direction of the first flow guiding member 12, among the 6 second flow guiding layers 1311 of the outer second flow guiding member 13, 4 of the 8 second flow guiding holes 13111 in one of the second flow guiding layers 1311 can be partially staggered from the second flow guiding holes 13111 in any one of the 8 second flow guiding holes 13111 in one of the second flow guiding layers 1311 of the inner second flow guiding member 13, or the second flow guiding holes 13111 in the 6 second flow guiding layers 1311 of the outer second flow guiding member 13 are all completely staggered from the second flow guiding holes 13111 in the 6 second flow guiding layers 1311 of the inner second flow guiding member 13, which is specifically set according to the actual situation and will not be exemplified one by one here. With such a setting, it is ensured that the multiple second flow guiding holes 13111 in the multiple second flow guiding layers 1311 of the outer second flow guiding member 13 and the multiple second flow guiding holes 13111 in the multiple second flow guiding layers 1311 of the inner second flow guiding member 13 are not completely opposite to each other.

[0106] Furthermore, when supercritical carbon dioxide enters the installation space 14 through the first through hole 111, part of the supercritical carbon dioxide flows from the installation space 14 into the second flow guiding space 16 through the second flow guiding holes 13111 in the multiple second flow guiding layers 1311 of the inner second flow guiding member 13. Subsequently, part of the supercritical carbon dioxide in the second flow guiding space 16 flows out through the second flow guiding holes 13111 in the multiple second flow guiding layers 1311 of the outer second flow guiding member 13. Since the multiple second flow guiding holes 13111 in the multiple second flow guiding layers 1311 of the outer second flow guiding member 13 and the multiple second flow guiding holes 13111 in the multiple second flow guiding layers 1311 of the inner second flow guiding member 13 are not completely opposite to each other, the second flow guiding holes 13111 staggered inside and outside further improve the multi-layer deceleration effect of the flow guiding structure 1, which is beneficial to further reducing the velocity of the supercritical carbon dioxide when flowing out from the second flow guiding part 131.

[0107] In some embodiments of the present application, the size of the second diversion hole 13111 on the inner side is greater than or equal to the size of the second diversion hole 13111 on the outer side. In this way, combined with the dislocation distribution of the second diversion hole 13111 on the outer side of the second diversion hole 13111 on the inner side, a step-by-step pressure boosting effect can be formed, which can reduce the energy loss caused by turbulence while reducing the injection speed of supercritical carbon dioxide.

[0108] In some embodiments of the present application, such as Figure 1 and Figure 6 shown, the plugging structure 2 includes a plugging member 21 and a fixing member 22. The plugging member 21 is used to plug the first through hole 111, and the fixing member 22 is used to fixedly connect the plugging member 21 and the substrate 11. The fixing member 22 is configured to break when the external pressure received by the plugging member 21 is greater than the preset breaking force of the fixing member 22, so that the plugging member 21 is opened. That is to say, when supercritical carbon dioxide is transported to the first through hole 111 of the diversion structure 1, the supercritical carbon dioxide in the first through hole 111 will exert an external pressure on the plugging member 21 plugging the first through hole 111. If the fixing member 22 breaks when the external pressure received by the plugging member 21 is greater than the preset breaking force of the fixing member 22, the plugging member 21 will be opened under the impact of supercritical carbon dioxide, meeting the requirements of the plugging structure 2, and the structure is simple, reliable and low-cost.

[0109] In some embodiments of the present application, such as Figure 1 and Figure 6 shown, it further includes: a guiding member 3. The guiding member 3 is fixedly arranged in the installation space 14. The guiding member 3 has a guiding hole 31 extending along the axial direction of the first guiding member 12. The plugging member 21 has a guiding rod 211 corresponding to the guiding hole 31. The guiding rod 211 passes through the guiding hole 31 and is movable relative to the guiding hole 31. Along the thickness direction of the guiding member 3, the guiding member 3 has a through second through hole 32.

[0110] Specifically, when the plugging member 21 is opened under the impact of supercritical carbon dioxide, the guiding rod 211 of the plugging member 21 moves upward in the guiding hole 31 of the guiding member 3. In this way, under the guiding cooperation of the guiding rod 211 and the guiding hole 31, it is beneficial to improve the stability of the movement of the plugging member 21.

[0111] Further, the inner peripheral surface of the first flow guide member 12 has a mounting boss. The mounting boss is arranged circumferentially around the first flow guide member 12, and a through fourth through hole is formed axially along the first flow guide member 12. The guide member 3 is fixedly arranged on the mounting boss, so that the mounting boss and the guide member 3 together divide the installation space 14 into a first sub-space and a second sub-space. Along the thickness direction of the guide member 3, the guide member 3 has a through second through hole 32. The first sub-space and the second sub-space are adapted to communicate through the second through hole 32. Among them, the first sub-space is closer to the substrate 11 than the second sub-space. It should be noted that along the axial direction of the first flow guide member 12, at least part of the area of the second through hole 32 overlaps with the fourth through hole.

[0112] It can be understood that there can be multiple second through holes 32, and the multiple second through holes 32 are arranged at intervals in sequence along the circumferential direction of the guide member 3.

[0113] After the plugging member 21 is opened, a large flow of high-pressure supercritical carbon dioxide enters the first sub-space from the first through hole 111. Among them, part of the supercritical carbon dioxide sequentially passes through the fourth through hole and the second through hole 32 from the first sub-space and enters the second sub-space, and then is ejected from the open end of the second sub-space. With such a setting, the guide member 3 can block part of the supercritical carbon dioxide flowing out of the first sub-space, which is beneficial to reducing the speed of the supercritical carbon dioxide flowing out of the open end of the installation space 14 and is beneficial to further improving the drainage efficiency of the supercritical carbon dioxide.

[0114] In some embodiments of the present application, as Figure 1 shown, it further includes: a cover plate 4. The cover plate 4 is fixedly arranged in the installation space 14. The cover plate 4 is located on the side of the guide member 3 away from the substrate 11 and is spaced apart from the guide member 3. The cover plate 4 is used to cover the open end of the installation space 14. Along the thickness direction of the cover plate 4, the cover plate 4 has a through third through hole 41, so that the installation space 14 communicates with the outside through the third through hole 41.

[0115] Specifically, the outer peripheral surface of the cover plate 4 is fitted and assembled with the inner peripheral surface of the first flow guide member 12. The cover plate 4 can be fixedly connected to the first flow guide member 12 by welding. The cover plate 4 is arranged on the side of the guide member 3 away from the substrate 11 and is spaced apart from the guide member 3, so as to reserve space for the movement of the guide rod 211. The cover plate 4 is used to cover the open end of the installation space 14. Along the thickness direction of the cover plate 4, the cover plate 4 has a through third through hole 41, so that the second sub-space communicates with the outside through the third through hole 41. With such a setting, when part of the supercritical carbon dioxide sequentially passes through the fourth through hole and the second through hole 32 from the first sub-space and enters the second sub-space, the supercritical carbon dioxide in the second sub-space passes through the third through hole 41 of the cover plate 4 and is ejected outward, so as to further reduce the speed of the supercritical carbon dioxide flowing out of the open end of the installation space 14.
