Description

Technical Field

[0001] The present application relates to the technical field of diversion, and particularly to a diversion component, 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 out of 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 gas for drainage, such as air, nitrogen, carbon dioxide, etc. The principle of using carbon dioxide to undergo a phase change due to heating 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 water in the water tank to be quickly drained.

[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, resulting in an increase in its density, 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 diversion component, a drainage device and a vehicle for supercritical carbon dioxide. The diversion component can achieve a good 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.

[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 diversion component for supercritical carbon dioxide, including:

[0008] A diversion member, the diversion member includes a substrate. Along the thickness direction of the substrate, the substrate has a through first through hole, and the substrate has a first diversion portion protruding outward along the thickness direction of the substrate. Along the circumferential direction of the first through hole, the first diversion portion surrounds the first through hole to form an installation space, and a first diversion hole communicating with the installation space is provided on the outer peripheral wall of the first diversion portion;

[0009] A guiding member, the guiding member is fixedly arranged in the installation space. The guiding member is adapted to divide the installation space into a first sub-space and a second sub-space, and along the thickness direction of the guiding member, the guiding member has a through second through hole. The first sub-space and the second sub-space are adapted to communicate through the second through hole, wherein the first sub-space is closer to the substrate than the second sub-space;

[0010] The plugging member and the elastic member are arranged on the guiding member in an axially movable manner along the axis of the first diversion portion. At least a part of the plugging member is arranged in the first sub-space and is used for plugging the first through hole. The elastic member is clamped between the plugging member and the guiding member. The plugging member is configured to open when the external pressure applied to the plugging member is greater than the elastic force of the elastic member, so that the first through hole and the first sub-space are communicated.

[0011] For the diversion 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 member is greater than the elastic force of the elastic member, the plugging member opens to allow the supercritical carbon dioxide to enter the first sub-space through the first through hole. Part of the supercritical carbon dioxide entering the first sub-space enters the second sub-space through the second through hole, and then sprays outwards from the open end of the second sub-space. Another part sprays out from the first diversion hole of the first diversion portion. Among them, the guiding member and the first diversion portion can play a certain role in blocking and decelerating the flow of the supercritical carbon dioxide, which is beneficial to reducing the velocity of the supercritical carbon dioxide when flowing out of the diversion assembly. Thus, while ensuring a large flow of supercritical carbon dioxide, this diversion assembly can achieve a good 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, this diversion assembly is small in volume and high in integration, and is suitable for various narrow spaces.

[0012] Optionally, the inner peripheral surface of the first diversion portion has a mounting boss, the mounting boss is arranged around the circumference of the first diversion portion, and the mounting boss is formed with a through third through hole along the axis of the first diversion portion;

[0013] The guiding member is fixedly arranged on the mounting boss, so that the mounting boss and the guiding member jointly divide the mounting space into a first sub-space and a second sub-space, and at least part of the area of the second through hole overlaps with the third through hole along the axis of the first diversion portion.

[0014] With such a setting, the guiding member can play a certain role in blocking and decelerating the supercritical carbon dioxide, which is beneficial to reducing the velocity of the supercritical carbon dioxide when flowing out from the open end of the second sub-space.

[0015] Optionally, there are multiple second through holes, and the multiple second through holes are arranged at intervals in sequence along the circumference of the guiding member.

[0016] With such a setting, not only can the supercritical carbon dioxide flowing out from the guiding member be made more uniform, but the design of multiple second through holes can also make the supercritical carbon dioxide spray more dispersedly, thereby further reducing the velocity of the supercritical carbon dioxide when flowing out from the second diversion portion.

[0017] Optionally, the blocking member includes a connected blocking portion and a guide rod, the guide member has a guide hole extending axially along the first guide portion, the guide rod is inserted into the guide hole and is movable relative to the guide hole, the blocking portion is arranged in the first subspace and is used to block the first through hole, and the elastic member is sleeved on the guide rod and clamped between the blocking portion and the guide member.

[0018] Such arrangement, under the guiding cooperation between the guide rod and the guide hole, is conducive to improving the stability of the movement of the blocking member.

[0019] Optionally, it also includes: a baffle, which is arranged in the second sub-space, the baffle is located on the side of the guide member away from the substrate and is separated from the guide member, the outer circumferential surface of the baffle is matched with the inner circumferential surface of the first guide part, and along the thickness direction of the baffle, the baffle has at least one fourth through hole to connect the second sub-space with the outside through the fourth through hole.

[0020] With such arrangement, when part of the supercritical carbon dioxide passes through the second through hole from the first subspace into the second subspace, the supercritical carbon dioxide in the second subspace needs to pass through the fourth through hole of the baffle before it can be sprayed out. This is equivalent to providing an extra layer of baffle in the second subspace, which can have a secondary deceleration effect on the supercritical carbon dioxide in the second subspace, and is beneficial to further reduce the speed of the supercritical carbon dioxide flowing out from the open end of the second subspace.

[0021] Optionally, there are multiple baffles, which are arranged in sequence and spaced apart along the axial direction of the first guide portion, two adjacent baffles and the first guide portion jointly form a first guide space, and the fourth through holes of two adjacent baffles are connected through the first guide space.

[0022] With this arrangement, the supercritical carbon dioxide in the second subspace needs to pass through the multi-layer baffles before it can be sprayed out, thereby improving the multi-layer deceleration effect of the baffles, thereby facilitating further reducing the speed of the supercritical carbon dioxide flowing out from the open end of the second subspace.

[0023] Optionally, along the axial direction of the first air guide portion, a projection of at least a partial area of ​​the fourth through hole of the outer spoiler of two adjacent spoilers is staggered with the fourth through hole of the inner spoiler.

[0024] In this way, the staggered fourth through holes on different flow-blocking members further enhance the multi-layer deceleration effect of the multiple flow-blocking members, thereby facilitating further reducing the speed of the supercritical carbon dioxide flowing out of the second guide portion.

[0025] Optionally, the substrate further has a second guide portion protruding outwardly along the thickness direction of the substrate, and the second guide portion is arranged on the same side as the first guide portion;

[0026] Circumferentially along the first diversion part, the second diversion part is arranged around the first diversion part, and radially along the first diversion part, the second diversion part is arranged at intervals outside the first diversion part, so that the first diversion part, the second diversion part and the substrate jointly form a second diversion space;

[0027] The outer peripheral wall of the second diversion part is provided with second diversion holes, and the second diversion holes are communicated with the first diversion holes through the second diversion space.

[0028] With such an arrangement, the second diversion part can further block and decelerate the supercritical carbon dioxide ejected from the first diversion holes, which is beneficial to reducing the velocity of the supercritical carbon dioxide when it is ejected from the diversion assembly.

[0029] Optionally, there are a plurality of second diversion parts. Radially along the first diversion part, the plurality of second diversion parts are arranged at intervals in sequence. The adjacent two second diversion parts and the substrate jointly form a third diversion space, and the second diversion holes of the adjacent two second diversion parts are communicated through the third diversion space.

[0030] With such an arrangement, by arranging a plurality of second diversion parts, the flow of supercritical carbon dioxide can be further blocked and decelerated, and the multi-layer deceleration effect of the diversion part can be further improved, which is beneficial to further reducing the velocity of the supercritical carbon dioxide when it flows out of the second diversion part.

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

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

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

[0034] For the vehicle proposed in the third aspect embodiment of the present application, by providing the above-mentioned drainage device, the diversion assembly of the drainage device can achieve a good deceleration effect on the supercritical carbon dioxide while ensuring a large flow of supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

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

[0054] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "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 it can be the communication inside two components.

[0057] At present, various waterborne or underwater vehicles need to adjust the overall buoyancy by filling and draining water tanks, and 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, 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.

[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, 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.

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

[0061] Based on this, the present application proposes a diversion component 100 for a drainage device 1000. When the pressure of external large-flow high-pressure supercritical carbon dioxide acting on the plugging member 3 is greater than the elastic force of the elastic member 4, the plugging member 3 opens to enable supercritical carbon dioxide to enter the first sub-space 1141 through the first through-hole 111. Part of the supercritical carbon dioxide entering the first sub-space 1141 enters the second sub-space 1142 from the second through-hole 21, and then sprays out from the open end of the second sub-space 1142. Another part sprays out from the first diversion holes 1121 of the first diversion part 112. Among them, the guiding member 2 and the first diversion part 112 can play a certain role in blocking and decelerating the flow of supercritical carbon dioxide, which is beneficial to reducing the speed of supercritical carbon dioxide flowing out of the diversion component 100. Thus, the diversion component 100 can achieve a good deceleration effect on supercritical carbon dioxide while ensuring large-flow supercritical carbon dioxide, which is beneficial to reducing heat transfer, thereby improving the drainage efficiency of supercritical carbon dioxide. At the same time, the diversion component 100 has a small volume and high 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 - 5 shown, the diversion component 100 according to the first aspect embodiment of the present application includes: a diversion member 1, a guiding member 2, a plugging member 3, and an elastic member 4.

[0064] Among them, the flow guide member 1 includes a substrate 11. Along the thickness direction of the substrate 11, the substrate 11 has a through first through hole 111, and the substrate 11 has a first flow guide portion 112 protruding outward along the thickness direction of the substrate 11. Along the circumference of the first through hole 111, the first flow guide portion 112 is arranged around the first through hole 111 to form an installation space 114. A first flow guide hole 1121 communicating with the installation space 114 is provided on the outer peripheral wall of the first flow guide portion 112.

[0065] Specifically, the first flow guide portion 112 can be configured as an annular structure. The first flow guide portion 112 is arranged around the first through hole 111 along the circumference 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 portion 112 is spaced apart from the first through hole 111. In this way, the first flow guide portion 112 and the substrate 11 together form a cylindrical installation space 114. Among them, one end of the installation space 114 away from the substrate 11 is an open end. A first flow guide hole 1121 communicating with the installation space 114 is provided on the outer peripheral wall of the first flow guide portion 112. Among them, there can be multiple first flow guide holes 1121. The multiple first flow guide holes 1121 can be arranged at intervals along the circumference of the first flow guide portion 112 to form a first flow guide layer. Further, there can be multiple first flow guide layers. The multiple first flow guide layers are arranged at intervals along the axial direction of the first flow guide portion 112 to form a first flow guide region.

[0066] In some embodiments of the present application, the guide member 2 is fixedly arranged in the installation space 114. The guide member 2 is adapted to divide the installation space 114 into a first sub-space 1141 and a second sub-space 1142. Along the thickness direction of the guide member 2, the guide member 2 has a through second through hole 21. The first sub-space 1141 and the second sub-space 1142 are adapted to communicate through the second through hole 21. Among them, the first sub-space 1141 is closer to the substrate 11 than the second sub-space 1142.

[0067] Specifically, the guide member 2 can be configured as a cylindrical structure. The guide member 2 is fixedly installed in the installation space 114 and is spaced apart from the substrate 11 along the axial direction of the first flow guide portion 112. The outer peripheral surface of the guide member 2 is fitted with the inner peripheral surface of the first flow guide portion 112 to divide the installation space 114 into a first sub-space 1141 and a second sub-space 1142. Among them, along the axial direction of the first flow guide portion 112, the second sub-space 1142 is located outside the first sub-space 1141. Further, along the thickness direction of the guide member 2, the guide member 2 has a through second through hole 21 to enable the first sub-space 1141 to communicate with the second sub-space 1142 through the second through hole 21.

[0068] In some embodiments of the present application, along the axial direction of the first diversion portion 112, the plugging member 3 is movably disposed on the guiding member 2. For example, taking the placement direction of the diversion assembly 100 as shown in Figure 3 as an example for illustration, the axial direction of the first diversion portion 112 is the height direction of the diversion assembly 100. The plugging member 3 can move up and down relative to the guiding member 2 along the axial direction of the first diversion portion 112. At least a part of the plugging member 3 is disposed in the first sub-space 1141 and is used to plug the first through-hole 111. The elastic member 4 is clamped between the plugging member 3 and the guiding member 2. The plugging member 3 is configured to open when the external pressure received by the plugging member 3 is greater than the elastic force of the elastic member 4, so that the first through-hole 111 and the first sub-space 1141 are communicated.

[0069] Further, to enable those skilled in the art to better understand the present application, as shown in Figure 1 the present application is described by taking the diversion assembly 100 used in the drainage device 1000 as an example.

[0070] Specifically, as shown in Figure 1 the drainage device 1000 includes a power unit 200. The power unit 200 has a storage chamber. The present application is described by taking the storage of liquid carbon dioxide in the storage chamber as an example. Further, the power unit 200 is fixedly connected to the diversion member 1 through a connecting pipe 300. Specifically, the connecting pipe 300 is fixedly connected to the substrate 11 of the diversion member 1 and is located on the side of the substrate 11 away from the first diversion portion 112. Among them, the connecting pipe 300 is communicated with the first through-hole 111. Under some specific conditions, when the liquid carbon dioxide in the storage chamber is transformed into supercritical carbon dioxide, the supercritical carbon dioxide is transported along the connecting pipe 300 to the first through-hole 111 of the diversion member 1. The supercritical carbon dioxide in the first through-hole 111 will exert an external pressure on the plugging member 3 plugging the first through-hole 111. If the external pressure received by the plugging member 3 is greater than the elastic force of the elastic member 4, the plugging member 3 will open. When the plugging member 3 opens, the high-flow high-pressure supercritical carbon dioxide in the connecting pipe 300 enters the first sub-space 1141 from the first through-hole 111. Among them, a part of the supercritical carbon dioxide in the first sub-space 1141 enters the second sub-space 1142 through the second through-hole 21, and then sprays out from the open end of the second sub-space 1142. It can be understood that when the supercritical carbon dioxide sprays out from the open end of the second sub-space 1142, the guiding member 2 can play a certain role in blocking and decelerating the flow of the supercritical carbon dioxide, which is beneficial to reducing the speed of the supercritical carbon dioxide flowing out from the open end of the second sub-space 1142.

[0071] Furthermore, since the outer peripheral wall of the first diversion part 112 is provided with a first diversion hole 1121 communicating with the installation space 114, another part of the supercritical carbon dioxide flowing into the first sub-space 1141 and / or the second sub-space 1142 can be ejected from the first diversion hole 1121 of the first diversion part 112, and the first diversion part 112 can play a certain role in blocking and decelerating the flow of the supercritical carbon dioxide, which is beneficial to further reducing the velocity of the supercritical carbon dioxide when flowing out of the diversion assembly 100.

[0072] In this way, while ensuring a large flow rate of supercritical carbon dioxide, the diversion assembly 100 can achieve a good deceleration effect on the supercritical carbon dioxide flowing into the diversion member 1 by arranging the guiding member 2 and the first diversion part 112, which is beneficial to reducing heat transfer and thus improving the drainage efficiency of the supercritical carbon dioxide.

[0073] It should be noted that when the supercritical carbon dioxide stops being transported, the elastic member 4 can drive the plugging member 3 to return to its original position, so that the plugging part 31 plugs the first through hole 111 again, realizing the reuse of the diversion member 1. At the same time, the diversion assembly 100 in the present application is relatively simple and small in volume, meeting the spraying requirements of high-pressure supercritical carbon dioxide with a large flow rate, and has a high integration degree, being applicable to various narrow spaces.

[0074] In summary, the diversion assembly 100 proposed in the first aspect embodiment of the present application for the drainage device 1000 can achieve a good deceleration effect on the supercritical carbon dioxide while ensuring a large flow rate of supercritical carbon dioxide, which is beneficial to reducing heat transfer and thus improving the drainage efficiency of the supercritical carbon dioxide. At the same time, the diversion assembly 100 is small in volume and has a high integration degree, being applicable to various narrow spaces.

[0075] In some embodiments of the present application, as Figure 3 and Figure 4 shown, the inner peripheral surface of the first diversion part 112 has an installation boss 1122, the installation boss 1122 is arranged around the circumference of the first diversion part 112, and a through third through hole 1123 is formed along the axial direction of the first diversion part 112. The guiding member 2 is fixedly arranged on the installation boss 1122, so that the installation boss 1122 and the guiding member 2 jointly divide the installation space 114 into a first sub-space 1141 and a second sub-space 1142, and at least part of the area of the second through hole 21 overlaps with the third through hole 1123 along the axial direction of the first diversion part 112.

[0076] Specifically, an annular mounting boss 1122 is provided on the inner peripheral surface of the first flow guiding portion 112. The annular mounting boss 1122 encloses a third through hole 1123. Along the axial direction of the first flow guiding portion 112, the mounting boss 1122 has a first end face and a second end face which are oppositely arranged. Among them, the first end face is farther from the substrate 11 than the second end face, that is, along the axial direction of the first flow guiding portion 112, the first end face is located outside the second end face. Further, the guiding member 2 is fitted and assembled with the first end face of the mounting boss 1122, so that the mounting boss 1122 and the guiding member 2 jointly divide the mounting space 114 into a first sub-space 1141 and a second sub-space 1142. It should be noted that at least part of the area of the second through hole 21 overlaps with the third through hole 1123. For example, when the second through hole 21 projects along the axial direction of the first flow guiding portion 112 towards the third through hole 1123, the projection of the second through hole 21 completely overlaps with the third through hole 1123, or the projection of the second through hole 21 does not completely overlap with the third through hole 1123. When the high-pressure supercritical carbon dioxide enters the first sub-space 1141 from the first through hole 111, part of the high-pressure supercritical carbon dioxide sequentially passes through the third through hole 1123 and the second through hole 21 and enters the second sub-space 1142, and then sprays outwards from the open end of the second sub-space 1142. With such a setting, the guiding member 2 can play a certain role in blocking and decelerating the supercritical carbon dioxide, which is beneficial to reducing the speed of the supercritical carbon dioxide when flowing out from the open end of the second sub-space 1142.

[0077] In some embodiments of the present application, as Figure 5 shown, there are multiple second through holes 21, and the multiple second through holes 21 are sequentially arranged at intervals along the circumferential direction of the guiding member 2. That is to say, multiple second through holes 21 can be provided on the guiding member 2. For example, the number of the second through holes 21 can be 2, 3, 4, 5, which can be specifically set according to the actual situation and will not be specifically limited here. Further, the multiple second through holes 21 are sequentially arranged at intervals along the circumferential direction of the guiding member 2, which can not only make the supercritical carbon dioxide flowing out from the guiding member 2 more uniform, but also enable the supercritical carbon dioxide to be sprayed more dispersedly by the design of the multiple second through holes 21, thereby further reducing the speed of the supercritical carbon dioxide when flowing out from the second flow guiding portion 113.

[0078] In some embodiments of the present application, as Figure 1As shown, the plugging member 3 includes a connected plugging portion 31 and a guide rod 32. The guiding member 2 has a guiding hole 22 extending along the axial direction of the first diversion portion 112. The guide rod 32 is inserted into the guiding hole 22 and is movable relative to the guiding hole 22. The plugging portion 31 is disposed in the first sub-space 1141 and is used to plug the first through-hole 111. The elastic member 4 is sleeved on the guide rod 32 and is clamped between the plugging portion 31 and the guiding member 2. Specifically, when the plugging portion 31 is opened under the impact of supercritical carbon dioxide, the guide rod 32 of the plugging member 3 moves upward in the guiding hole 22 of the guiding member 2. Thus, under the guiding cooperation of the guide rod 32 and the guiding hole 22, it is beneficial to improve the moving stability of the plugging member 3. Further, when the supercritical carbon dioxide stops being conveyed, the elastic member 4 can drive the plugging portion 31 back to its original position so that the plugging portion 31 plugs the first through-hole 111 again.

[0079] In some embodiments of the present application, as Figure 2 and Figure 3 shown, it further includes: a flow blocking member 5. The flow blocking member 5 is disposed in the second sub-space 1142. The flow blocking member 5 is located on the side of the guiding member 2 away from the substrate 11 and is spaced apart from the guiding member 2. The outer peripheral surface of the flow blocking member 5 is fitted and assembled with the inner peripheral surface of the first diversion portion 112. Along the thickness direction of the flow blocking member 5, the flow blocking member 5 has at least one through fourth through-hole 51 so that the second sub-space 1142 communicates with the outside through the fourth through-hole 51.

[0080] Specifically, the outer peripheral surface of the flow blocking member 5 is fitted and assembled with the inner peripheral surface of the first diversion portion 112. The flow blocking member 5 can be fixedly connected to the first diversion portion 112 by welding. The flow blocking member 5 is disposed on the side of the guiding member 2 away from the substrate 11 and is spaced apart from the guiding member 2, so as to reserve space for the movement of the guide rod 32. Along the thickness direction of the flow blocking member 5, the flow blocking member 5 has at least one through fourth through-hole 51 so that the second sub-space 1142 communicates with the outside through the fourth through-hole 51. For example, the number of the fourth through-holes 51 can be 2, 3, 4, 5, and the diameters of the multiple fourth through-holes 51 can be the same or different. The multiple fourth through-holes 51 with the same diameter can be sequentially spaced around the circumference of the flow blocking member 5, which is specifically set according to actual needs and is not specifically limited here.

[0081] With such a setting, when part of the supercritical carbon dioxide passes from the first sub-space 1141 through the second through-hole 21 into the second sub-space 1142, the supercritical carbon dioxide in the second sub-space 1142 needs to pass through the fourth through-hole 51 of the flow blocking member 5 to spray outwards. It is equivalent to adding an additional layer of blocking member in the second sub-space 1142, which can play a secondary deceleration role on the supercritical carbon dioxide in the second sub-space 1142 and is beneficial to further reduce the velocity of the supercritical carbon dioxide flowing out from the open end of the second sub-space 1142.

[0082] In some embodiments of the present application, there are multiple flow restrictors 5. Along the axial direction of the first flow guiding portion 112, the multiple flow restrictors 5 are arranged at intervals in sequence. A first flow guiding space is jointly formed by two adjacent flow restrictors 5 and the first flow guiding portion 112, and the fourth through holes 51 of two adjacent flow restrictors 5 are communicated through the first flow guiding space.

[0083] That is to say, along the axial direction of the first flow guiding portion 112, multiple flow restrictors 5 arranged at intervals in sequence are provided in the second sub-space 1142. It can be understood that a first flow guiding space is jointly formed by the inner peripheral surfaces of any two adjacent flow restrictors 5 and the first flow guiding portion 112, and the fourth through holes 51 of two adjacent flow restrictors 5 are communicated through the first flow guiding space. That is to say, when a part of supercritical carbon dioxide enters the second sub-space 1142 from the first sub-space 1141, along the axial direction of the first flow guiding portion 112, the supercritical carbon dioxide sequentially passes through the fourth through holes 51 of each flow restrictor 5 from the inside to the outside, and then sprays out the supercritical carbon dioxide from the fourth through hole 51 of the outermost flow restrictor 5. With such a setting, the supercritical carbon dioxide in the second sub-space 1142 needs to pass through multiple layers of flow restrictors 5 to spray outwards, improving the multi-layer deceleration effect of the flow restrictors 5, which is thus conducive to further reducing the velocity of the supercritical carbon dioxide when flowing out from the open end of the second sub-space 1142.

[0084] In some embodiments of the present application, a flow restricting portion can be provided in the first flow guiding space. For example, by adding micro flow guiding fins or honeycomb structures in the first flow guiding space to guide the supercritical carbon dioxide to form a laminar flow, it is beneficial to reduce the temperature rise caused by turbulence, which is thus conducive to reducing heat exchange and further enhancing the stability of the supercritical carbon dioxide.

[0085] In some embodiments of the present application, along the axial direction of the first flow guiding portion 112, at least a part of the region of the fourth through hole 51 of the outer flow restrictor 5 among two adjacent flow restrictors 5 is offset from the fourth through hole 51 of the inner flow restrictor 5.

[0086] Specifically, when multiple flow restrictors 5 arranged at intervals in sequence are provided in the second sub-space 1142, along the axial direction of the first flow guiding portion 112, the projection of at least a part of the region of the fourth through hole 51 of the outer flow restrictor 5 among two adjacent flow restrictors 5 is offset from the fourth through hole 51 of the inner flow restrictor 5.

[0087] For example, it is assumed that there are two flow restrictors 5 arranged at intervals in the second sub-space 1142. Among them, along the axial direction of the first flow guiding portion 112, the projection of at least a part of the region of the fourth through hole 51 of the outer flow restrictor 5 is offset from the fourth through hole 51 of the inner flow restrictor 5. For example, with the flow guiding assembly 100 in accordance with Figure 3Taking the shown placement direction as an example for illustration, the axial direction of the first flow guiding portion 112 is the height direction of the flow guiding assembly 100. That is, in the height direction of the flow guiding assembly 100, a partial area projection of the fourth through hole 51 of the outer flow blocking member 5 is offset from the fourth through hole 51 of the inner flow blocking member 5, or the projection of the fourth through hole 51 of the outer flow blocking member 5 is completely offset from the fourth through hole 51 of the inner flow blocking member 5. It is specifically set according to the actual situation and is not specifically limited here, so as to ensure that the projection of the fourth through hole 51 of the outer flow blocking member 5 along the axial direction of the first flow guiding portion 112 is not completely opposite to the fourth through hole 51 of the inner flow blocking member 5. When supercritical carbon dioxide passes through any two flow blocking members 5, the fourth through holes 51 arranged in a staggered manner on different flow blocking members 5 are beneficial to further improving the multi-layer deceleration effect of the plurality of flow blocking members 5, and thus are beneficial to further reducing the velocity of the supercritical carbon dioxide when flowing out from the open end of the second sub-space 1142.

[0088] It can be understood that if the number of the fourth through holes 51 of the outer flow blocking member 5 and the number of the fourth through holes 51 of the inner flow blocking member 5 can both be multiple, it is necessary to ensure that the projection of the multiple fourth through holes 51 of the outer flow blocking member 5 along the axial direction of the first flow guiding portion 112 is not completely opposite to the multiple fourth through holes 51 of the inner flow blocking member 5.

[0089] In some embodiments of the present application, along the axial direction of the first flow guiding portion 112, the fourth through hole 51 can be designed with a gradient aperture. For example, the size of the fourth through hole 51 of the inner flow blocking member 5 is greater than or equal to the size of the fourth through hole 51 of the outer flow blocking member 5. In this way, combined with the staggered distribution of the fourth through hole 51 of the inner flow blocking member 5 and the fourth through hole 51 of the outer flow blocking member 5, a step-by-step pressure boosting effect can be formed, and while reducing the injection velocity of the supercritical carbon dioxide, the energy loss caused by turbulence can be reduced.

[0090] In some embodiments of the present application, a convex structure or a grid structure can be provided in the fourth through hole 51, which can reduce the velocity of the supercritical carbon dioxide when flowing out from the fourth through hole 51, and thus is beneficial to further reducing heat transfer and improving the drainage efficiency.

[0091] In some embodiments of the present application, such as Figures 2 - 5As shown, the substrate 11 further has a second flow guiding portion 113 that protrudes outward in the thickness direction of the substrate 11. The second flow guiding portion 113 is arranged on the same side as the first flow guiding portion 112. Along the circumferential direction of the first flow guiding portion 112, the second flow guiding portion 113 surrounds the first flow guiding portion 112. And along the radial direction of the first flow guiding portion 112, the second flow guiding portion 113 is arranged at intervals outside the first flow guiding portion 112, so that the first flow guiding portion 112, the second flow guiding portion 113 and the substrate 11 jointly form a second flow guiding space 115. The outer peripheral wall of the second flow guiding portion 113 is provided with second flow guiding holes 1131, and the second flow guiding holes 1131 are communicated with the first flow guiding holes 1121 through the second flow guiding space 115.

[0092] Specifically, the second flow guiding portion 113 can also be constructed as an annular structure. The second flow guiding portion 113 surrounds the first flow guiding portion 112 along the circumferential direction of the first flow guiding portion 112. And along the radial direction of the first flow guiding portion 112, as Figure 3 shown, the second flow guiding portion 113 is arranged at intervals from the first flow guiding portion 112, and the second flow guiding portion 113 is arranged outside the first flow guiding portion 112. In this way, the first flow guiding portion 112, the second flow guiding portion 113 and the substrate 11 jointly form an annular second flow guiding space 115. Among them, one end of the second flow guiding space 115 away from the substrate 11 is an open end. Further, the outer peripheral wall of the second flow guiding portion 113 is provided with second flow guiding holes 1131, and the second flow guiding holes 1131 are communicated with the first flow guiding holes 1121 through the second flow guiding space 115. When the supercritical carbon dioxide enters the second flow guiding space 115 from the installation space 114, the supercritical carbon dioxide cannot be directly ejected to the outside. After being blocked and decelerated by the second flow guiding portion 113, it is ejected from the second flow guiding holes 1131. That is to say, the second flow guiding portion 113 can further block and decelerate the supercritical carbon dioxide ejected from the first flow guiding holes 1121, which is beneficial to reducing the velocity of the supercritical carbon dioxide when it is ejected from the flow guiding assembly 100.

[0093] It should be noted that there can be multiple second flow guiding holes 1131. The multiple second flow guiding holes 1131 can be arranged at intervals along the circumferential direction of the second flow guiding portion 113 to form a second flow guiding layer. Further, there can be multiple second flow guiding layers, and the multiple second flow guiding layers are arranged at intervals along the axial direction of the second flow guiding portion 113 to form a second flow guiding region.

[0094] It can be understood that at least part of the second flow guiding region is staggered from the first flow guiding region along the axial direction and / or the circumferential direction of the first flow guiding portion 112.

[0095] That is to say, at least part of the second flow guiding region is staggered from the first flow guiding region along the axial direction of the first flow guiding portion 112. For example, taking the flow guiding assembly 100 in accordance with Figure 3Taking the placement direction shown as an example for illustration, the axial direction of the first flow guiding portion 112 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 region is offset from the first flow guiding region. It can be understood that part of the second flow guiding region can be offset vertically from the first flow guiding region. Further, the second flow guiding region can also be completely offset vertically from the first flow guiding region, which is specifically set according to the actual situation and is not specifically limited here;

[0096] Or, along the circumferential direction of the first flow guiding portion 112, at least part of the second flow guiding region is offset from the first flow guiding region. For example, continuing to take the flow guiding assembly 100 arranged in the Figure 3 placement direction shown as an example for illustration, the second flow guiding region of the second flow guiding portion 113 is arranged around the first flow guiding portion 112 along the circumferential direction of the first flow guiding portion 112. Among them, part of the second flow guiding region can be offset circumferentially from the first flow guiding region. Further, the second flow guiding region can also be completely offset circumferentially from the first flow guiding region, which is specifically set according to the actual situation and is not specifically limited here;

[0097] Or, along the axial and circumferential directions of the first flow guiding portion 112, at least part of the second flow guiding region is offset from the first flow guiding region. For example, continuing to take the flow guiding assembly 100 arranged in the Figure 3 placement direction shown 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 portion 112, part of the second flow guiding region can be offset from the first flow guiding region. Further, the second flow guiding region can also be completely offset from the first flow guiding region, which is specifically set according to the actual situation and is not specifically limited here. With such a setting, it is ensured that the first flow guiding region on the first flow guiding portion 112 is not completely opposite to the second flow guiding region on the second flow guiding portion 113.

[0098] As a specific example, if the first flow guiding portion 112 has a first flow guiding layer and the second flow guiding portion 113 has a second flow guiding layer, then along the axial and / or circumferential directions of the first flow guiding portion 112, at least part of the second flow guiding layer is offset from the first flow guiding layer.

[0099] That is to say, along the axial direction of the first flow guiding portion 112, at least part of the second flow guiding layer is offset from the first flow guiding layer. Continuing to take the flow guiding assembly 100 arranged in the Figure 3Taking the shown placement direction as an example for illustration, assume that the first diversion layer includes 8 first diversion holes 1121 arranged at intervals along the circumferential direction of the first diversion part 112, and the second diversion layer includes 8 second diversion holes 1131 arranged at intervals along the circumferential direction of the second diversion part 113. For example, 4 of the 8 second diversion holes 1131 can be partially offset up and down with some of the 8 first diversion holes 1121 in the height direction of the diversion assembly 100, 4 of the 8 second diversion holes 1131 are all offset up and down with the 8 first diversion holes 1121 in the height direction of the diversion assembly 100, or all 8 second diversion holes 1131 are offset up and down with the 8 first diversion holes 1121 in the height direction of the diversion assembly 100. It is specifically set according to the actual situation and will not be elaborated one by one here;

[0100] Or, along the circumferential direction of the first diversion part 112, at least part of the area of the second diversion layer is offset from the first diversion layer. Continuing to take the diversion assembly 100 in the Figure 3 shown placement direction as an example for illustration. For example, the 8 second diversion holes 1131 of the second diversion layer are arranged around the first diversion layer along the circumferential direction of the first diversion layer. Among them, 4 of the 8 second diversion holes 1131 can be partially offset circumferentially with some of the 8 first diversion holes 1121, or 4 of the 8 second diversion holes 1131 are all offset circumferentially with the 8 first diversion holes 1121, or all 8 second diversion holes 1131 are offset circumferentially with the 8 first diversion holes 1121. It is specifically set according to the actual situation and will not be elaborated one by one here;

[0101] Or, along the axial and circumferential directions of the first diversion part 112, at least part of the area of the second diversion layer is offset from the first diversion layer. Continuing to take the diversion assembly 100 in the Figure 3 shown placement direction as an example for illustration. For example, in the height direction of the diversion assembly 100 and along the circumferential direction of the first diversion part 112, 4 of the 8 second diversion holes 1131 can be partially offset with some of the 8 first diversion holes 1121, or 4 of the 8 second diversion holes 1131 are all offset with the 8 first diversion holes 1121, or all 8 second diversion holes 1131 are offset with the 8 first diversion holes 1121. It is specifically set according to the actual situation and will not be elaborated one by one here. With such a setting, it is ensured that the multiple first diversion holes 1121 of the first diversion layer and the multiple second diversion holes 1131 of the second diversion layer are not completely opposite.

[0102] Further, as a specific example, when supercritical carbon dioxide enters the installation space 114 through the first through-hole 111, part of the supercritical carbon dioxide flows into the first diversion space from the plurality of first diversion holes 1121. Since the plurality of first diversion holes 1121 are circumferentially spaced along the first diversion portion 112, the first diversion portion 112 can play a certain role in blocking and decelerating the flow of supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flowing into the second diversion space 115 flows out from the plurality of second diversion holes 1131 of the second diversion portion 113. Since the plurality of first diversion holes 1121 of the first diversion layer and the plurality of second diversion holes 1131 of the second diversion layer are not completely opposite to each other, part of the supercritical carbon dioxide flowing out from the first diversion holes 1121 is blocked by part of the second diversion portion 113 and then flows out from the second diversion holes 1131, achieving a good multi-layer deceleration effect and reducing the velocity of the supercritical carbon dioxide when it flows out from the second diversion portion 113.

[0103] Further, as another specific example, if the first diversion portion 112 has a plurality of first diversion layers and the second diversion portion 113 has a plurality of second diversion layers, then at least part of at least some regions of the plurality of second diversion layers are offset from the corresponding first diversion layers along the axial direction and / or the circumferential direction of the first diversion portion 112.

[0104] That is to say, along the axial direction of the first diversion portion 112, at least part of at least some regions of the plurality of second diversion layers are offset from the corresponding first diversion layers. Continuing to take the diversion component 100 as an example in the placement direction shown Figure 3 For illustration, assume that the first diversion region includes 2 first diversion layers, and each first diversion layer includes 8 first diversion holes 1121 circumferentially spaced along the first diversion portion 112. The second diversion region includes 6 second diversion layers, and each second diversion layer includes 8 second diversion holes 1131 circumferentially spaced along the second diversion portion 113. For example, among the 6 second diversion layers, 4 of the 8 second diversion holes 1131 in one of the second diversion layers can be partially offset up and down in the height direction of the diversion component 100 from the 8 first diversion holes 1121 in any one of the first diversion layers, or the 6 second diversion layers are offset up and down from the 2 first diversion layers in the height direction of the diversion component 100, which is specifically set according to the actual situation and will not be elaborated one by one here;

[0105] Or, along the circumferential direction of the first diversion portion 112, at least part of at least some regions of the plurality of second diversion layers are offset from the corresponding first diversion layers. Continuing to take the diversion component 100 as an example in the placement direction shown Figure 3Taking the shown placement direction as an example for illustration, assume that the first diversion area includes 2 first diversion layers, and each first diversion layer includes 8 first diversion holes 1121 arranged at intervals along the circumferential direction of the first diversion part 112. The second diversion area includes 6 second diversion layers, and each second diversion layer includes 8 second diversion holes 1131 arranged at intervals along the circumferential direction of the second diversion part 113. For example, among the 6 second diversion layers, 4 of the 8 second diversion holes 1131 in one of the second diversion layers can be partially circumferentially staggered from the 8 first diversion holes 1121 in any one of the first diversion layers, or each second diversion hole 1131 in the 6 second diversion layers can be completely circumferentially staggered from the first diversion holes 1121 in 2 first diversion layers, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0106] Or, along the axial and circumferential directions of the first diversion part 112, at least part of the areas of at least some of the second diversion layers among the multiple second diversion layers are staggered from the corresponding first diversion layers. Continuing to take the diversion assembly 100 in the Figure 3 shown placement direction as an example for illustration, assume that the first diversion area includes 2 first diversion layers, and each first diversion layer includes 8 first diversion holes 1121 arranged at intervals along the circumferential direction of the first diversion part 112. The second diversion area includes 6 second diversion layers, and each second diversion layer includes 8 second diversion holes 1131 arranged at intervals along the circumferential direction of the second diversion part 113. For example, in the height direction of the diversion assembly 100 and along the circumferential direction of the first diversion part 112, among the 6 second diversion layers, 4 of the 8 second diversion holes 1131 in one of the second diversion layers can be partially staggered from the 8 first diversion holes 1121 in any one of the first diversion layers, or each second diversion hole 1131 in the 6 second diversion layers can be completely staggered from the first diversion holes 1121 in 2 first diversion layers, 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 diversion holes 1121 of the multiple first diversion layers and the multiple second diversion holes 1131 of the multiple second diversion layers are not completely opposite.

[0107] Further, as a specific example, when supercritical carbon dioxide enters the installation space 114 through the first through-hole 111, a part of the supercritical carbon dioxide flows into the second diversion space 115 from the first diversion holes 1121 in the plurality of first diversion layers. While meeting the injection requirements, it is beneficial to further reduce the outflow speed of the supercritical carbon dioxide from the first diversion part 112, improve the blocking and decelerating effect of the first diversion part 112 on the supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flowing into the second diversion space 115 flows out from the second diversion holes 1131 in the plurality of second diversion layers. Since the plurality of first diversion holes 1121 in the plurality of first diversion layers and the plurality of second diversion holes 1131 in the plurality of second diversion layers are not completely opposite, a part of the supercritical carbon dioxide flowing out from the first diversion holes 1121 is blocked by a part of the second diversion part 113 and then flows out from the second diversion holes 1131, achieving a good multi-layer deceleration effect. Moreover, the setting of the multi-layer second diversion layers is also beneficial to further reduce the outflow speed of the supercritical carbon dioxide from the second diversion area.

[0108] In some embodiments of the present application, as Figures 3 - 5 shown, there are a plurality of second diversion parts 113. Along the radial direction of the first diversion part 112, the plurality of second diversion parts 113 are sequentially arranged at intervals. A third diversion space 116 is jointly formed by two adjacent second diversion parts 113 and the substrate 11, and the second diversion holes 1131 of two adjacent second diversion parts 113 communicate through the third diversion space 116.

[0109] Specifically, the flow guide member 1 can be provided with a plurality of second diversion parts 113 in a ring structure. Among them, along the radial direction of the first diversion part 112, each second diversion part 113 is arranged at intervals outside the first diversion part 112, and the plurality of second diversion parts 113 are sequentially arranged at intervals. In this way, a ring-shaped third diversion space 116 is jointly formed by two adjacent second diversion parts 113 and the substrate 11. Further, the second diversion holes 1131 of two adjacent second diversion parts 113 communicate through the third diversion space 116 formed by these two adjacent second diversion parts 113.

[0110] For example, referring to Figure 4As shown in the figure, two second flow guiding parts 113 are arranged on the outer side of the first flow guiding part 112. Among them, a second flow guiding space 115 is formed between the inner second flow guiding part 113 and the first flow guiding part 112, and a third flow guiding space 116 is formed between the outer second flow guiding part 113 and the inner second flow guiding part 113. The second flow guiding holes 1131 of the inner second flow guiding part 113 communicate with the second flow guiding holes 1131 of the outer second flow guiding part 113 through the third flow guiding space 116. When supercritical carbon dioxide enters the installation space 114 through the first through hole 111, part of the supercritical carbon dioxide flows into the second flow guiding space 115 and the third flow guiding space 116 in sequence from the installation space 114, and then sprays out from the second flow guiding holes 1131 of the outer second flow guiding part 113.

[0111] It can be understood that if three second flow guiding parts 113 are arranged on the outer side of the first flow guiding part 112, two third flow guiding spaces 116 are formed by the three second flow guiding parts 113. When supercritical carbon dioxide enters the installation space 114 through the first through hole 111, the supercritical carbon dioxide flows from the installation space 114 into the second flow guiding space 115, and then sprays out from the second flow guiding holes 1131 of the outermost second flow guiding part 113 after passing through the two third flow guiding spaces 116 in sequence from the second flow guiding space 115. Thus, by arranging a plurality of second flow guiding parts 113, the flow of supercritical carbon dioxide can be further blocked and decelerated, and the multi-layer deceleration effect of the flow guiding part 1 can be further improved, which is beneficial to further reducing the speed of supercritical carbon dioxide when flowing out from the second flow guiding part 113.

[0112] In some embodiments of the present application, as Figures 3 - 5 shown in the figure, along the axial direction and / or circumferential direction of the first flow guiding part 112, at least part of the area of the second flow guiding holes 1131 of the outer second flow guiding part 113 among two adjacent second flow guiding parts 113 is staggered from the second flow guiding holes 1131 of the inner second flow guiding part 113.

[0113] Specifically, assume that two second flow guiding parts 113 are arranged on the outer side of the first flow guiding part 112. Along the axial direction and / or circumferential direction of the first flow guiding part 112, at least part of the area of the second flow guiding holes 1131 of the outer second flow guiding part 113 is staggered from the second flow guiding holes 1131 of the inner second flow guiding part 113. That is to say, along the axial direction of the first flow guiding part 112, at least part of the area of the second flow guiding holes 1131 of the outer second flow guiding part 113 is staggered from the second flow guiding holes 1131 of the inner second flow guiding part 113. For example, taking the flow guiding assembly 100 according to Figure 3Taking the shown placement direction as an example for illustration, the axial direction of the first diversion part 112 is the height direction of the diversion assembly 100. That is, in the height direction of the diversion assembly 100, at least part of the area of the second diversion holes 1131 of the outer second diversion part 113 and the second diversion holes 1131 of the inner second diversion part 113 can be partially staggered vertically. It can be understood that part of the area of the second diversion holes 1131 of the outer second diversion part 113 and the second diversion holes 1131 of the inner second diversion part 113 are vertically staggered. Further, part of the area of the second diversion holes 1131 of the outer second diversion part 113 can also be completely vertically staggered with the second diversion holes 1131 of the inner second diversion part 113, which is specifically set according to the actual situation and is not specifically limited here;

[0114] Or, along the circumferential direction of the first diversion part 112, at least part of the area of the second diversion holes 1131 of the outer second diversion part 113 and the second diversion holes 1131 of the inner second diversion part 113 are staggered. For example, continuing to take the diversion assembly 100 in the Figure 3 shown placement direction as an example for illustration, the second diversion holes 1131 of the outer second diversion part 113 are arranged around the circumferential direction of the inner second diversion part 113. Among them, part of the area of the second diversion holes 1131 of the outer second diversion part 113 can be partially circumferentially staggered with the second diversion holes 1131 of the inner second diversion part 113. Further, part of the area of the second diversion holes 1131 of the outer second diversion part 113 can also be completely circumferentially staggered with the second diversion holes 1131 of the inner second diversion part 113, which is specifically set according to the actual situation and is not specifically limited here;

[0115] Or, along the axial and circumferential directions of the first diversion part 112, at least part of the area of the second diversion holes 1131 of the outer second diversion part 113 and the second diversion holes 1131 of the inner second diversion part 113 are staggered. For example, continuing to take the diversion assembly 100 in the Figure 3 shown placement direction as an example for illustration, that is, in the height direction of the diversion assembly 100 and along the circumferential direction of the first diversion part 112, part of the area of the second diversion holes 1131 of the outer second diversion part 113 can be partially staggered with the second diversion holes 1131 of the inner second diversion part 113. Further, part of the area of the second diversion holes 1131 of the outer second diversion part 113 can also be completely staggered with the second diversion holes 1131 of the inner second diversion part 113, which is specifically set according to the actual situation and is not specifically limited here.

[0116] Further, as a specific example, there may be a plurality of second diversion holes 1131. The plurality of second diversion holes 1131 may be arranged at intervals around the circumferential direction of the second diversion portion 113 to form a second diversion layer. Further, there may be a plurality of second diversion layers. The plurality of second diversion layers may be arranged at intervals along the axial direction of the second diversion portion 113 to form a second diversion region.

[0117] Thus, the second diversion regions of the second diversion portions 113 on the outer side and the second diversion regions of the second diversion portions 113 on the inner side both include a plurality of second diversion layers. Among them, the plurality of second diversion layers of the second diversion portion 113 on the outer side are arranged at intervals along the axial direction of the second diversion portion 113 on the outer side, and the plurality of second diversion layers of the second diversion portion 113 on the inner side are arranged at intervals along the axial direction of the second diversion portion 113 on the inner side. The second diversion layer on the outer side includes a plurality of second diversion holes 1131 arranged at intervals around the circumferential direction of the second diversion portion 113 on the outer side, and the second diversion layer on the inner side includes a plurality of second diversion holes 1131 arranged at intervals around the circumferential direction of the second diversion portion 113 on the inner side. Along the axial direction and / or circumferential direction of the first diversion portion 112, at least some regions of at least some of the plurality of second diversion layers of the second diversion portion 113 on the outer side are staggered from the corresponding second diversion layers of the second diversion portion 113 on the inner side.

[0118] That is to say, along the axial direction of the first diversion portion 112, at least some regions of at least some of the plurality of second diversion layers of the second diversion portion 113 on the outer side are staggered from the corresponding second diversion layers of the second diversion portion 113 on the inner side. Continuing to take the diversion assembly 100 arranged in Figure 3 the placement direction shown as an example for illustration. Suppose the second diversion portion 113 on the outer side includes 6 second diversion layers, and each second diversion layer of the second diversion portion 113 on the outer side includes 8 second diversion holes 1131 arranged at intervals around the circumferential direction of the second diversion portion 113 on the outer side. The second diversion portion 113 on the inner side includes 6 second diversion layers, and each second diversion layer of the second diversion portion 113 on the inner side includes 8 second diversion holes 1131 arranged at intervals around the circumferential direction of the second diversion portion 113 on the inner side. For example, among the 6 second diversion layers of the second diversion portion 113 on the outer side, 4 of the 8 second diversion holes 1131 in one of the second diversion layers may be partially staggered up and down in the height direction of the diversion assembly 100 from the 8 second diversion holes 1131 in any one of the second diversion layers of the second diversion portion 113 on the inner side, or the 6 second diversion layers of the second diversion portion 113 on the outer side may be staggered up and down in the height direction of the diversion assembly 100 from the 6 second diversion layers of the second diversion portion 113 on the inner side. It is specifically set according to the actual situation, and no further examples will be given here;

[0119] Alternatively, along the circumferential direction of the first diversion portion 112, at least some regions of at least some of the plurality of second diversion layers of the outer second diversion portion 113 are offset from the corresponding second diversion layers of the inner second diversion portion 113. Continuing with the diversion assembly 100 as an example in the Figure 3 shown placement direction, assume that the outer second diversion portion 113 includes 6 second diversion layers, and each second diversion layer of the outer second diversion portion 113 includes 8 second diversion holes 1131 arranged at intervals along the circumferential direction of the outer second diversion portion 113. The inner second diversion portion 113 includes 6 second diversion layers, and each second diversion layer of the inner second diversion portion 113 includes 8 second diversion holes 1131 arranged at intervals along the circumferential direction of the inner second diversion portion 113. For example, among the 6 second diversion layers of the outer second diversion portion 113, 4 of the 8 second diversion holes 1131 in one of the second diversion layers can be partially circumferentially offset from the second diversion holes 1131 among the 8 second diversion holes 1131 in any one of the second diversion layers of the inner second diversion portion 113. Alternatively, the second diversion holes 1131 in the 6 second diversion layers of the outer second diversion portion 113 can be completely circumferentially offset from the second diversion holes 1131 in the 6 second diversion layers of the inner second diversion portion 113, which is specifically set according to the actual situation and will not be exemplified one by one here;

[0120] Alternatively, along the axial and circumferential directions of the first diversion portion 112, at least some regions of at least some of the plurality of second diversion layers of the outer second diversion portion 113 are offset from the corresponding second diversion layers of the inner second diversion portion 113. Continuing with the diversion assembly 100 as an example in the Figure 3Taking the shown placement direction as an example for illustration, it is assumed that the second flow guiding part 113 on the outer side includes 6 second flow guiding layers, and each second flow guiding layer of the second flow guiding part 113 on the outer side includes 8 second flow guiding holes 1131 arranged at intervals along the circumferential direction of the second flow guiding part 113 on the outer side. The second flow guiding part 113 on the inner side includes 6 second flow guiding layers, and each second flow guiding layer of the second flow guiding part 113 on the inner side includes 8 second flow guiding holes 1131 arranged at intervals along the circumferential direction of the second flow guiding part 113 on the inner side. For example, in the height direction of the flow guiding assembly 100 and along the circumferential direction of the first flow guiding part 112, among the 6 second flow guiding layers of the second flow guiding part 113 on the outer side, 4 of the 8 second flow guiding holes 1131 in one of the second flow guiding layers can be partially staggered from the second flow guiding holes 1131 in any one of the 8 second flow guiding holes 1131 in the second flow guiding layer of the second flow guiding part 113 on the inner side, or the second flow guiding holes 1131 in the 6 second flow guiding layers of the second flow guiding part 113 on the outer side are all completely staggered from the second flow guiding holes 1131 in the 6 second flow guiding layers of the second flow guiding part 113 on the inner side, 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 1131 of the multiple second flow guiding layers in the second flow guiding part 113 on the outer side and the multiple second flow guiding holes 1131 of the multiple second flow guiding layers in the second flow guiding part 113 on the inner side are not completely opposite.

[0121] Furthermore, when supercritical carbon dioxide enters the installation space 114 through the first through hole 111, part of the supercritical carbon dioxide flows from the installation space 114 into the third flow guiding space 116 through the second flow guiding holes 1131 in the multiple second flow guiding layers of the second flow guiding part 113 on the inner side. Subsequently, part of the supercritical carbon dioxide in the third flow guiding space 116 flows out through the second flow guiding holes 1131 in the multiple second flow guiding layers of the second flow guiding part 113 on the outer side. Since the multiple second flow guiding holes 1131 of the multiple second flow guiding layers in the second flow guiding part 113 on the outer side and the multiple second flow guiding holes 1131 of the multiple second flow guiding layers in the second flow guiding part 113 on the inner side are not completely opposite, the second flow guiding holes 1131 arranged in a staggered manner inside and outside further improve the multi-layer deceleration effect of the flow guiding assembly 100, which is beneficial to further reducing the velocity of the supercritical carbon dioxide when flowing out through the second flow guiding holes 1131.
