Description

Technical Field

[0001] The present application relates to the field of diversion technology, and in particular to a diversion component, a drainage device and a vehicle for supercritical carbon dioxide. Background Art

[0002] At present, various water or underwater vehicles need to adjust the overall buoyancy by filling and draining water from the water tank. The existing filling and draining methods mainly include pump-driven drainage and air-driven drainage.

[0003] Among them, gas-driven drainage uses high-pressure compressible gas to drain water, such as air, nitrogen, carbon dioxide, etc. It uses the principle of carbon dioxide undergoing phase change when heated to drain water, which has the advantage of large drainage flow rate compared to air and nitrogen. Carbon dioxide is liquid at a certain pressure and temperature, and can quickly transform into a supercritical state after increasing temperature and pressure, with its volume expanding several times and strong instantaneous work capacity, and can quickly drain water from the water tank.

[0004] However, due to the high injection speed and high temperature of large-flow supercritical carbon dioxide, it is easily cooled by water in the initial drainage stage, which increases its density and affects its 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 guide assembly, a drainage device and a vehicle for supercritical carbon dioxide. The guide assembly can achieve a good multi-layer deceleration effect on the supercritical carbon dioxide while ensuring a large flow of supercritical carbon dioxide, which is beneficial to reducing heat transfer and thus improving the drainage efficiency of the supercritical carbon dioxide.

[0006] In order to achieve the above objectives, the main technical solutions adopted in this application include: In a first aspect, an embodiment of the present application provides a flow guide assembly for supercritical carbon dioxide, comprising: A flow guide structure, the flow guide structure comprises a substrate, a first flow guide member and a second flow guide member, the substrate has a first through hole along the thickness direction of the substrate, and the first flow guide member and the second flow guide member are both located on the same side of the substrate along the thickness direction of the substrate; The first flow guide is fixedly connected to the substrate, and is arranged around the first through hole along the circumference of the first through hole, so that the first flow guide and the substrate jointly form an installation space; The second flow guide is fixedly connected to the substrate. The second flow guide is arranged around the first flow guide along the circumferential direction of the first flow guide, and the second flow guide is arranged at intervals outside the first flow guide along the radial direction of the first flow guide, so that the first flow guide, the second flow guide and the substrate jointly form a first flow guide space. The outer peripheral wall of the first flow guide is provided with a first flow guide portion which is in communication with both the installation space and the first flow guide space, and the outer peripheral wall of the second flow guide is provided with a second flow guide portion, the second flow guide portion is in communication with the first flow guide portion through the first flow guide space, and along the axial direction and / or circumferential direction of the first flow guide, at least a part of the second flow guide portion is staggered with the first flow guide portion; The blocking structure is arranged in the installation space, is used to block the first through hole and is fixedly connected to the substrate, and is constructed to open when the external pressure applied to the blocking structure is greater than a preset value, so as to connect the first through hole and the installation space.

[0007] The first aspect of the present application proposes a flow guide assembly for supercritical carbon dioxide, when the pressure of the external large-flow high-pressure supercritical carbon dioxide acting on the blocking structure is greater than a preset value, the blocking structure is opened to allow the supercritical carbon dioxide to enter the installation space through the first through hole, and the supercritical carbon dioxide entering the installation space flows from the first flow guide portion of the first flow guide into the first flow guide space, wherein the first flow guide can play a certain blocking and decelerating role on the flow of supercritical carbon dioxide, and then the supercritical carbon dioxide flows out from the second flow guide portion of the second flow guide, because along the axial and / or circumferential direction of the first flow guide, at least part of the area of ​​the second flow guide portion is staggered with the first flow guide portion, so that part of the supercritical carbon dioxide flowing out of the first flow guide portion can be blocked by the second flow guide, reducing the speed of the supercritical carbon dioxide flowing out of the second flow guide portion. Thus, the flow guide assembly can play a good multi-layer deceleration effect on the supercritical carbon dioxide while ensuring a large flow of supercritical carbon dioxide, which is conducive to reducing heat transfer, thereby improving the drainage efficiency of supercritical carbon dioxide, and at the same time, the flow guide assembly is small in size and highly integrated, and is suitable for various narrow spaces.

[0008] Optionally, the first guide portion includes a first guide layer, and the first guide layer includes a plurality of first guide holes arranged at intervals along the circumferential direction of the first guide member; The second guide portion includes a second guide layer, which includes a plurality of second guide holes spaced apart along the circumferential direction of the second guide member. Along the axial direction and / or circumferential direction of the first guide member, at least a portion of the second guide layer is staggered with the first guide layer.

[0009] Since at least a partial area of ​​the second guide layer is staggered with the first guide layer along the axial and / or circumferential direction of the first guide member, the multiple first guide holes of the first guide layer are not completely opposite to the multiple second guide holes of the second guide layer, thereby causing part of the supercritical carbon dioxide flowing out of the first guide holes to be blocked by part of the second guide member and then flow out from the second guide holes, thereby achieving a good multi-layer deceleration effect and reducing the speed of the supercritical carbon dioxide flowing out of the second guide portion.

[0010] Optionally, there are multiple first guide layers, and the multiple first guide layers are arranged at intervals along the axial direction of the first guide member; There are multiple second guide layers, which are arranged at intervals along the axial direction of the second guide member. Along the axial direction and / or circumferential direction of the first guide member, at least partial areas of at least some of the multiple second guide layers are staggered with the corresponding first guide layers.

[0011] Since the multiple first guide holes of the multiple first guide layers are not completely opposite to the multiple second guide holes of the multiple second guide layers, part of the supercritical carbon dioxide flowing out of the first guide holes is blocked by part of the second guide members and then flows out from the second guide holes, which has a good multi-layer deceleration effect. The multi-layer second guide layer setting is also conducive to further reducing the speed of the supercritical carbon dioxide flowing out of the second guide part.

[0012] Optionally, there are multiple second flow guide members, which are arranged in sequence and spaced apart along the radial direction of the first flow guide member, two adjacent second flow guide members and the substrate jointly form a second flow guide space, and the second flow guide parts of two adjacent second flow guide members are connected through the second flow guide space.

[0013] Therefore, by providing multiple second guide members, the flow of supercritical carbon dioxide can be further blocked and decelerated, and the multi-layer deceleration effect of the guide structure can be further improved, which is beneficial to further reduce the speed of supercritical carbon dioxide flowing out of the second guide part.

[0014] Optionally, along the axial direction and / or circumferential direction of the first flow guide member, at least a partial area of ​​the second flow guide portion of the outer second flow guide member of two adjacent second flow guide members is staggered with the second flow guide portion of the inner second flow guide member.

[0015] Since the multiple second guide holes of the multiple second guide layers in the outer second guide member are not completely opposite to the multiple second guide holes of the multiple second guide layers in the inner second guide member, part of the supercritical carbon dioxide flowing out of the second guide holes in the inner second guide member is passed through part of the inner second guide member and then flows out from the second guide holes of the outer second guide member. The second guide holes staggered inside and outside further improve the multi-layer deceleration effect of the guide structure, which is beneficial to further reduce the speed of the supercritical carbon dioxide flowing out of the second guide part.

[0016] Optionally, the sealing structure includes a sealing piece and a fixing piece, the sealing piece is used to seal the first through hole, the fixing piece is used to fix the sealing piece and the substrate, and the fixing piece is constructed to break when the external pressure applied to the sealing piece is greater than a preset breaking force of the fixing piece, so that the sealing piece can be opened.

[0017] If the external pressure on the plugging piece is greater than the preset breaking force of the fixing piece, the fixing piece will break, and the plugging piece will open under the impact of supercritical carbon dioxide, meeting the requirements of the plugging structure, and the structure is simple, reliable and low-cost.

[0018] Optionally, it further comprises: a guide member, the guide member is fixed in the installation space, the guide member has a guide hole extending along the axial direction of the first flow guide member, the blocking member has a guide rod arranged corresponding to the guide hole, the guide rod is passed through the guide hole and is movable relative to the guide hole; The guide member has a second through hole extending through the guide member along the thickness direction of the guide member.

[0019] Such an arrangement, with the guiding cooperation of the guide rod and the guide hole, is conducive to improving the stability of the movement of the sealing member, and the guide member can block part of the supercritical carbon dioxide flowing out of the first subspace, thereby helping to reduce the speed of the supercritical carbon dioxide flowing out from the open end of the installation space, and is conducive to further improving the drainage efficiency of the supercritical carbon dioxide.

[0020] Optionally, it also includes: a cover plate, which is fixed in the installation space, the cover plate is located on the side of the guide member away from the substrate and is spaced apart from the guide member, the cover plate is used to seal the open end of the installation space, and along the thickness direction of the cover plate, the cover plate has a through third through hole so that the installation space is connected with the outside through the third through hole.

[0021] With such arrangement, when part of the supercritical carbon dioxide passes through the fourth through hole and the second through hole from the first subspace in sequence into the second subspace, the supercritical carbon dioxide in the second subspace is ejected outward through the third through hole of the cover plate, thereby further reducing the speed of the supercritical carbon dioxide flowing out from the open end of the installation space.

[0022] In a second aspect, an embodiment of the present application provides a drainage device, comprising the guide assembly in the embodiment of the first aspect.

[0023] The drainage device proposed in the second aspect of the embodiment of the present application is provided with the above-mentioned guide component. While ensuring a large flow rate of supercritical carbon dioxide, the guide component can have a good multi-layer deceleration effect on the supercritical carbon dioxide, which is beneficial to reduce heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide, and further improving the drainage efficiency of the drainage device.

[0025] The aircraft proposed in the third aspect of the present application is provided with the above-mentioned drainage device. The guide component of the drainage device can have a good multi-layer deceleration effect on the supercritical carbon dioxide while ensuring a large flow of supercritical carbon dioxide, which is beneficial to reduce heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide and further improving the buoyancy regulation efficiency of the aircraft.

[0035] At present, various water or underwater vehicles need to adjust the overall buoyancy by filling and draining water from the water tank. The existing filling and draining methods mainly include pump-driven drainage and air-driven drainage.

[0036] Among them, gas-driven drainage uses high-pressure compressible gas to drain water, such as air, nitrogen, carbon dioxide, etc. It uses the principle of carbon dioxide undergoing phase change when heated to drain water, which has the advantage of large drainage flow rate compared to air and nitrogen. Carbon dioxide is liquid at a certain pressure and temperature, and can quickly transform into a supercritical state after increasing temperature and pressure, with its volume expanding several times and strong instantaneous work capacity, and can quickly drain water from the water tank.

[0037] However, due to the high injection speed and high temperature of large-flow supercritical carbon dioxide, it is easily cooled by water in the initial drainage stage, which increases its density and affects its expansion drainage capacity. Therefore, it is necessary to improve the drainage efficiency of supercritical carbon dioxide while ensuring the flow rate.

[0038] In the related art, the ejection speed of supercritical carbon dioxide is usually reduced by increasing the diameter of the supercritical carbon dioxide pipeline or using a gas diffuser. However, the above methods have the disadvantages of occupying a large space volume and a complex structure, and are difficult to be used in places with limited space.

[0039] Based on this, the present application proposes a guide assembly 100 for supercritical carbon dioxide. When the pressure of external large-flow high-pressure supercritical carbon dioxide acting on the sealing structure 2 is greater than a preset value, the sealing 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 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 flows out from the second guide portion 131 of the second guide member 13. Since at least a portion of the second guide portion 131 is staggered with the first guide portion 121 along the axial and / or circumferential direction of the first guide member 12, part of the supercritical carbon dioxide flowing out of the first guide portion 121 can be blocked by the second guide member 13, thereby further reducing the speed of the supercritical carbon dioxide flowing out of the second guide portion 131. Therefore, the guide component 100 can achieve a good multi-layer deceleration effect on the supercritical carbon dioxide while ensuring a large flow of supercritical carbon dioxide, which is beneficial to reduce heat transfer and thus improve the drainage efficiency of the supercritical carbon dioxide. At the same time, the guide component 100 is small in size and highly integrated, and is suitable for various narrow spaces.

[0040] The following describes the flow guide assembly 100, drainage device 1000 and aircraft for supercritical carbon dioxide proposed in the embodiments of the present application with reference to the accompanying drawings.

[0041] like Figure 1-Figure 6 As shown, the flow guide assembly 100 according to the first embodiment of the present application includes: a flow guide structure 1 and a blocking structure 2.

[0042] Among them, the guide structure 1 includes a substrate 11, a first guide member 12 and a second guide member 13. Along the thickness direction of the substrate 11, the substrate 11 has a first through hole 111, and along the thickness direction of the substrate 11, the first guide member 12 and the second guide member 13 are both located on the same side of the substrate 11, that is, the first guide member 12 and the second guide member 13 are arranged on the same end surface of the substrate 11.

[0043] Furthermore, the first flow guide 12 is fixedly connected to the substrate 11 , and is disposed around the first through hole 111 along the circumference of the first through hole 111 , so that the first flow guide 12 and the substrate 11 together form an installation space 14 .

[0044] Specifically, one end of the first flow guide 12 is fixedly connected to the substrate 11, and the other end extends along the thickness direction of the substrate 11 toward a direction away from the substrate 11. The first flow guide 12 can be constructed as an annular structure. The first flow guide 12 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 12 is separated from the first through hole 111. In this way, the first flow guide 12 and the substrate 11 jointly form a cylindrical installation space 14, wherein the end of the installation space 14 away from the substrate 11 is an open end.

[0045] Furthermore, the second flow guide member 13 is fixedly connected to the substrate 11, and is arranged around the first flow guide member 12 along the circumference of the first flow guide member 12, and is arranged at intervals on the outside of the first flow guide member 12 along the radial direction of 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.

[0046] Specifically, one end of the second guide member 13 is fixedly connected to the substrate 11, and the other end extends in the thickness direction of the substrate 11 in a direction away from the substrate 11. The second guide member 13 can also be configured as an annular structure. The second guide member 13 is arranged around the first guide member 12 along the circumference of the first guide member 12, and along the radial direction of the first guide member 12, such as Figure 2 As 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 arranged on the outside of the first flow guide member 12, so that the first flow guide member 12, the second flow guide member 13 and the substrate 11 together form an annular first flow guide space 15, wherein the end of the first flow guide space 15 away from the substrate 11 is an open end.

[0047] Furthermore, the outer peripheral wall of the first guide member 12 is provided with a first guide portion 121 which is connected to the installation space 14 and the first guide space 15, and the outer peripheral wall of the second guide member 13 is provided with a second guide portion 131, and the second guide portion 131 is connected to the first guide portion 121 through the first guide space 15. Optionally, a flow blocking portion can be arranged in the first guide space 15, for example, by adding micro guide fins or honeycomb structures to the outer peripheral wall of the first guide member 12 and / or the inner peripheral wall of the second guide member 13 to guide the supercritical carbon dioxide to form a laminar flow, which is beneficial to reduce the temperature rise caused by turbulence, thereby helping to reduce heat exchange and further improve the stability of the supercritical carbon dioxide.

[0048] Further, along the axial direction and / or circumferential direction of the first air guide 12 , at least a partial area of ​​the second air guide portion 131 is staggered from the first air guide portion 121 .

[0049] For example, the flow guide assembly 100 is Figure 2 Taking the placement direction shown as an example, the axial direction of the first guide member 12 is the height direction of the guide assembly 100, that is, in the height direction of the guide assembly 100, at least a portion of the second guide portion 131 is staggered with the first guide portion 121. It can be understood that a portion of the second guide portion 131 can be staggered with the first guide portion 121 up and down, and further, the second guide portion 131 can also be completely staggered with the first guide portion 121 up and down, which is specifically set according to actual conditions and is not specifically limited here; Alternatively, along the circumference of the first guide member 12, at least a portion of the second guide portion 131 is staggered from the first guide portion 121. For example, the guide assembly 100 is continued as follows: Figure 2 Taking the placement direction shown in the figure as an example, the second guide portion 131 of the second guide member 13 is arranged around the first guide member 12 along the circumference of the first guide member 12, wherein a part of the second guide portion 131 may be circumferentially staggered with the first guide portion 121, and further, the second guide portion 131 may be completely circumferentially staggered with the first guide portion 121, which is specifically arranged according to actual conditions and is not specifically limited here; Alternatively, along the axial direction and the circumferential direction of the first flow guide 12, at least a portion of the second flow guide portion 131 is staggered from the first flow guide portion 121. For example, the flow guide assembly 100 is continued as follows: Figure 2The placement direction shown in the figure is used as an example for explanation, that is, in the height direction of the guide assembly 100 and along the circumference of the first guide 12, a part of the second guide 131 can be staggered with the first guide 121, and further, the second guide 131 can also be completely staggered with the first guide 121. The specific setting depends on the actual situation and is not specifically limited here. Such a setting ensures that the first guide 121 on the first guide 12 and the second guide 131 on the second guide 13 are not completely opposite.

[0050] Further, the blocking structure 2 is disposed 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, and the blocking structure 2 is configured to open when the external pressure applied to the blocking structure 2 is greater than a preset value, so that the first through hole 111 is connected to the installation space 14. In other words, the blocking structure 2 is fixedly connected to the substrate 11 and disposed in the installation space 14, and the blocking structure 2 is used to block the first through hole 111, and is configured to open when the external pressure applied to the blocking structure 2 is greater than a preset value, so that the first through hole 111 is connected to the installation space 14.

[0051] Furthermore, in order to enable those skilled in the art to better understand the present application, Figure 1 As shown, the present application is described by taking the diversion assembly 100 used in the drainage device 1000 as an example.

[0052] Specifically, Figure 1As 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.

[0053] 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.

[0054] To summarize, according to the first aspect of the present application, the guide assembly 100 for supercritical carbon dioxide can ensure a large flow of supercritical carbon dioxide while achieving a good multi-layer deceleration effect on the supercritical carbon dioxide, which is beneficial to reduce heat transfer, thereby improving the drainage efficiency of the supercritical carbon dioxide. At the same time, the guide assembly 100 is small in size and highly integrated, and is suitable for various narrow spaces.

[0055] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the first guide portion 121 includes a first guide layer 1211, the first guide layer 1211 includes a plurality of first guide holes 12111 arranged at intervals along the circumference of the first guide member 12, the second guide portion 131 includes a second guide layer 1311, the second guide layer 1311 includes a plurality of second guide holes 13111 arranged at intervals along the circumference of the second guide member 13, and along the axial and / or circumferential direction of the first guide member 12, at least a partial area of ​​the second guide layer 1311 is staggered with the first guide layer 1211.

[0056] Specifically, the first guide portion 121 can be constructed as a first guide layer 1211 composed of a plurality of first guide holes 12111 arranged at intervals along the circumference of the first guide member 12, and the second guide portion 131 can be constructed as a second guide layer 1311 composed of a plurality of second guide holes 13111 arranged at intervals along the circumference of the second guide member 13, wherein at least a partial area of ​​the second guide layer 1311 is staggered with the first guide layer 1211 along the axial and / or circumferential direction of the first guide member 12.

[0057] That is, along the axial direction of the first guide member 12, at least a portion of the second guide layer 1311 is staggered with the first guide layer 1211, so that the guide assembly 100 is arranged in accordance with Figure 4 Taking the placement direction shown as an example for explanation, it is assumed that the first guide layer 1211 includes 8 first guide holes 12111 arranged at intervals along the circumference of the first guide member 12, and the second guide layer 1311 includes 8 second guide holes 13111 arranged at intervals along the circumference of the second guide member 13. For example, 4 of the 8 second guide holes 13111 can be partially staggered up and down with some of the 8 first guide holes 12111 in the height direction of the guide component 100, 4 of the 8 second guide holes 13111 are staggered up and down with the 8 first guide holes 12111 in the height direction of the guide component 100, or the 8 second guide holes 13111 are all staggered up and down with the 8 first guide holes 12111 in the height direction of the guide component 100. The specific arrangement is based on actual conditions, and examples are not given one by one here. Alternatively, along the circumference of the first guide member 12, at least a portion of the second guide layer 1311 is staggered from the first guide layer 1211, and the guide assembly 100 is continued in accordance with Figure 4 The arrangement direction shown in the figure is taken as an example for explanation. For example, the eight second guide holes 13111 of the second guide layer 1311 are arranged around the first guide layer 1211 along the circumference of the first guide layer 1211, wherein four of the eight second guide holes 13111 and some of the eight first guide holes 12111 can be partially circumferentially staggered, or four of the eight second guide holes 13111 and the eight first guide holes 12111 are all circumferentially staggered, or the eight second guide holes 13111 and the eight first guide holes 12111 are all circumferentially staggered, and the specific arrangement is based on actual conditions, and examples are not given one by one here. Alternatively, along the axial direction and circumferential direction of the first guide member 12, at least a portion of the second guide layer 1311 is staggered from the first guide layer 1211, and the guide assembly 100 is continued in accordance with Figure 4 The placement direction shown in the figure is used as an example for explanation. For example, in the height direction of the guide assembly 100 and along the circumference of the first guide member 12, 4 of the 8 second guide holes 13111 and some of the 8 first guide holes 12111 can be partially staggered, or 4 of the 8 second guide holes 13111 and the 8 first guide holes 12111 are all staggered, or the 8 second guide holes 13111 and the 8 first guide holes 12111 are all staggered, and the specific setting is based on the actual situation, and examples are not given here one by one. Such a setting ensures that the multiple first guide holes 12111 of the first guide layer 1211 and the multiple second guide holes 13111 of the second guide layer 1311 are not completely opposite.

[0058] 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 guide space 15 from the multiple first guide holes 12111. Since the multiple first guide holes 12111 are distributed at circumferential intervals along the first guide member 12, the first guide member 12 can play a certain blocking and deceleration role on the flow of supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide that flows into the first guide space 15 flows out from the multiple second guide holes 13111 of the second guide member 13. Since the multiple first guide holes 12111 of the first guide layer 1211 are not completely opposite to the multiple second guide holes 13111 of the second guide layer 1311, part of the supercritical carbon dioxide flowing out of the first guide hole 12111 is blocked by part of the second guide member 13 and then flows out from the second guide hole 13111, which has a good multi-layer deceleration effect and reduces the speed of the supercritical carbon dioxide flowing out of the second guide part 131.

[0059] In some embodiments of the present application, the guide holes can be designed as gradient apertures along the radial direction of the first guide member 12. For example, the size of the first guide hole 12111 is greater than or equal to the size of the second guide hole 13111. In this way, combined with the staggered distribution of the first guide holes 12111 and the second guide holes 13111, a step-by-step diffusion effect can be formed, which can reduce the energy loss caused by turbulence while reducing the supercritical carbon dioxide injection speed.

[0060] In some embodiments of the present application, a protrusion structure or a grid structure can be set in the first guide hole 12111 and the second guide hole 13111, which can reduce the speed of supercritical carbon dioxide flowing out of the first guide hole 12111 and the second guide hole 13111, thereby further reducing heat transfer and improving drainage efficiency.

[0061] In some embodiments of the present application, Figure 3 and Figure 4 As shown, there are multiple first guide layers 1211, and the multiple first guide layers 1211 are arranged at intervals along the axial direction of the first guide member 12; there are multiple second guide layers 1311, and the multiple second guide layers 1311 are arranged at intervals along the axial direction of the second guide member 13; along the axial direction and / or circumferential direction of the first guide member 12, at least partial areas of at least some of the multiple second guide layers 1311 are staggered with the corresponding first guide layers 1211.

[0062] Specifically, the first guide portion 121 can be constructed to be composed of a plurality of first guide layers 1211 arranged at intervals along the axial direction of the first guide member 12, wherein the first guide layer 1211 includes a plurality of first guide holes 12111 arranged at intervals along the circumferential direction of the first guide member 12, and the second guide portion 131 can be constructed to be composed of a plurality of second guide layers 1311 arranged at intervals along the axial direction of the second guide member 13, wherein the second guide layer 1311 includes a plurality of second guide holes 13111 arranged at intervals along the circumferential direction of the second guide member 13, and further, along the axial direction and / or circumferential direction of the first guide member 12, at least partial areas of at least some of the plurality of second guide layers 1311 are staggered with the corresponding first guide layer 1211.

[0063] That is, along the axial direction of the first guide member 12, at least a portion of the second guide layers 1311 in the plurality of second guide layers 1311 are staggered with the corresponding first guide layer 1211, and the guide assembly 100 is continued in accordance with Figure 4 Assume that the first guide portion 121 includes two first guide layers 1211, each of which includes eight first guide holes 12111 arranged at intervals along the circumference of the first guide member 12, and the second guide portion 131 includes six second guide layers 1311, each of which includes eight second guide holes 13111 arranged at intervals along the circumference of the second guide member 13. For example, in the six second guide layers 131 1, 4 second guide holes 13111 among the 8 second guide holes 13111 in one second guide layer 1311 may be partially staggered up and down with the 8 first guide holes 12111 in any one first guide layer 1211 in the height direction of the guide component 100, or, 6 second guide layers 1311 may be staggered up and down with the 2 first guide layers 1211 in the height direction of the guide component 100, which is specifically set according to actual conditions, and will not be described one by one here; Alternatively, along the circumference of the first guide member 12, at least a portion of the second guide layers 1311 in the plurality of second guide layers 1311 are staggered with the corresponding first guide layer 1211, and the guide assembly 100 is continued in accordance with Figure 4Assume that the first guide portion 121 includes two first guide layers 1211, each of which includes eight first guide holes 12111 arranged at intervals along the circumference of the first guide member 12, and the second guide portion 131 includes six second guide layers 1311, each of which includes eight second guide holes 13111 arranged at intervals along the circumference of the second guide member 13. For example, in the six second guide layers 131 1, 4 second guide holes 13111 among the 8 second guide holes 13111 in one second guide layer 1311 and the 8 first guide holes 12111 in any one first guide layer 1211 may be partially circumferentially staggered, or each second guide hole 13111 in the 6 second guide layers 1311 and the first guide holes 12111 in the 2 first guide layers 1211 may be completely circumferentially staggered, which is specifically set according to actual conditions and will not be described one by one here; Alternatively, along the axial direction and the circumferential direction of the first guide member 12, at least a portion of the second guide layers 1311 in the plurality of second guide layers 1311 are staggered with the corresponding first guide layers 1211, and the guide assembly 100 is continued in accordance with Figure 4 1. The arrangement direction shown in FIG. 1 is used as an example for explanation. It is assumed that the first guide portion 121 includes two first guide layers 1211, each of which includes eight first guide holes 12111 arranged at intervals along the circumference of the first guide member 12, and the second guide portion 131 includes six second guide layers 1311, each of which includes eight second guide holes 13111 arranged at intervals along the circumference of the second guide member 13. For example, in the height direction of the guide component 100 and along the circumference of the first guide member 12, among the six second guide layers 1311, one second guide layer 1311 has eight second guide holes 13111 arranged at intervals along the circumference of the second guide member 13. Four of the eight second guide holes 13111 in the first guide layer 1211 can be partially staggered with the eight first guide holes 12111 in any one of the first guide layers 1211, or each of the second guide holes 13111 in the six second guide layers 1311 can be completely staggered with the first guide holes 12111 in the two first guide layers 1211. The specific arrangement is based on actual conditions and will not be described one by one here. Such an arrangement ensures that the multiple first guide holes 12111 in the multiple first guide layers 1211 are not completely opposite to the multiple second guide holes 13111 in the multiple second guide layers 1311.

[0064] 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 guide space 15 from the first guide hole 12111 in the plurality of first guide layers 1211, which is conducive to further reducing the speed of supercritical carbon dioxide flowing out of the first guide member 12 while meeting the injection demand, and improving the ability of the first guide member 12 to block and decelerate the supercritical carbon dioxide. Subsequently, the supercritical carbon dioxide flowing into the first guide space 15 flows out of the plurality of second guide layers 131. 1, because the multiple first guide holes 12111 of the multiple first guide layers 1211 are not completely opposite to the multiple second guide holes 13111 of the multiple second guide layers 1311, part of the supercritical carbon dioxide flowing out of the first guide holes 12111 is blocked by part of the second guide members 13 and then flows out from the second guide holes 13111, which has a good multi-layer deceleration effect, and the multi-layer second guide layer 1311 is also conducive to further reducing the speed of the supercritical carbon dioxide when it flows out from the second guide part 131.

[0065] In some embodiments of the present application, Figure 2-Figure 5 As shown, there are multiple second flow guide members 13, and along the radial direction of the first flow guide member 12, the multiple second flow guide members 13 are arranged in sequence at intervals, and two adjacent second flow guide members 13 and the substrate 11 together form a second flow guide space 16, and the second flow guide parts 131 of two adjacent second flow guide members 13 are connected through the second flow guide space 16.

[0066] Specifically, the flow guide structure 1 may be provided with a plurality of second flow guide members 13 of annular structure, wherein, along the radial direction of the first flow guide member 12, each second flow guide member 13 is arranged at intervals on the outside of the first flow guide member 12, and the plurality of second flow guide members 13 are arranged at intervals in sequence, so that two adjacent second flow guide members 13 and the substrate 11 jointly form an annular second flow guide space 16, and further, the second flow guide portions 131 of two adjacent second flow guide members 13 are connected through the second flow guide space 16 formed by the two adjacent second flow guide members 13. Optionally, a flow blocking portion may be provided in the second flow guide space 16, for example, by adding micro-flow guide fins and honeycomb structures in the second flow guide space 16 to guide the supercritical carbon dioxide to form a laminar flow, so that it is helpful to reduce the temperature rise caused by turbulence, thereby helping to reduce heat exchange, and thus improving the stability of the supercritical carbon dioxide.

[0067] For example, refer to Figure 3As shown, two second guide members 13 are provided on the outer side of the first guide member 12, wherein the inner second guide member 13 and the first guide member 12 form a first guide space 15, a second guide space 16 is formed between the outer second guide member 13 and the inner second guide member 13, and the second guide portion 131 of the inner second guide member 13 is connected with the second guide portion 131 of the outer second guide member 13 through the second guide space 16. 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 first guide space 15 and the second guide space 16 in sequence, and then is ejected from the second guide portion 131 of the outer second guide member 13.

[0068] It can be understood that if three second flow guides 13 are provided on the outside of the first flow guide 12, two second flow guide spaces 16 are formed in the three second flow guides 13. When the 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 guide space 15, and then passes through the two second flow guide spaces 16 in sequence from the first flow guide space 15 and then sprays out from the second flow guide portion 131 of the outermost second flow guide 13. Thus, by providing a plurality of second flow guides 13, the flow of supercritical carbon dioxide can be further blocked and decelerated, and the multi-layer deceleration effect of the flow guide structure 1 can be further improved, so as to further reduce the speed of the supercritical carbon dioxide flowing out of the second flow guide portion 131.

[0069] In some embodiments of the present application, Figure 3-Figure 5 As shown, along the axial direction and / or circumferential direction of the first flow guide 12 , at least a portion of the second flow guide portion 131 of the outer second flow guide 13 of two adjacent second flow guides 13 is staggered with the second flow guide portion 131 of the inner second flow guide 13 .

[0070] Specifically, when multiple second guide members 13 are provided on the outside of the first guide member 12, along the axial and / or circumferential direction of the first guide member 12, at least a partial area of ​​the second guide portion 131 of the outer second guide member 13 of two adjacent second guide members 13 is staggered with the second guide portion 131 of the inner second guide member 13.

[0071] For example, assuming that two second flow guide members 13 are disposed on the outer side of the first flow guide member 12, along the axial direction and / or circumferential direction of the first flow guide member 12, at least a portion of the second flow guide portion 131 of the outer second flow guide member 13 is staggered with the second flow guide portion 131 of the inner second flow guide member 13, that is, along the axial direction of the first flow guide member 12, at least a portion of the second flow guide portion 131 of the outer second flow guide member 13 is staggered with the second flow guide portion 131 of the inner second flow guide member 13. For example, the flow guide assembly 100 is arranged according to Figure 4Taking the placement direction shown as an example, the axial direction of the first flow guide 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 a partial area of ​​the second flow guide portion 131 of the outer second flow guide 13 is staggered with the second flow guide portion 131 of the inner second flow guide 13. It can be understood that a partial area of ​​the second flow guide portion 131 of the outer second flow guide 13 and the second flow guide portion 131 of the inner second flow guide 13 can be partially staggered up and down, and further, the second flow guide portion 131 of the outer second flow guide 13 can also be completely staggered up and down with the second flow guide portion 131 of the inner second flow guide 13, which is specifically set according to actual conditions and is not specifically limited here; Alternatively, along the circumference of the first guide member 12, at least a portion of the second guide portion 131 of the outer second guide member 13 is staggered with the second guide portion 131 of the inner second guide member 13. For example, the guide assembly 100 is continued as follows: Figure 4 Taking the placement direction shown in the figure as an example, the second guide portion 131 of the outer second guide member 13 is arranged around the circumference of the inner second guide member 13, wherein a partial area of ​​the second guide portion 131 of the outer second guide member 13 can be partially circumferentially staggered with the second guide portion 131 of the inner second guide member 13, and further, the second guide portion 131 of the outer second guide member 13 can also be completely circumferentially staggered with the second guide portion 131 of the inner second guide member 13, which is specifically arranged according to actual conditions and is not specifically limited here; Alternatively, along the axial direction and the circumferential direction of the first flow guide 12, at least a portion of the second flow guide portion 131 of the outer second flow guide 13 is staggered with the second flow guide portion 131 of the inner second flow guide 13. For example, the flow guide assembly 100 is continued according to Figure 4 The placement direction shown is taken as an example for explanation, that is, in the height direction of the guide assembly 100 and along the circumference of the first guide member 12, a partial area of ​​the second guide portion 131 of the outer second guide member 13 can be partially staggered with the second guide portion 131 of the inner second guide member 13, and further, the second guide portion 131 of the outer second guide member 13 can also be completely staggered with the second guide portion 131 of the inner second guide member 13. The specific arrangement is based on actual conditions and is not specifically limited here.

[0072] Further, as a specific example, the second guide portion 131 of the outer second guide member 13 and the second guide portion 131 of the inner second guide member 13 both include a plurality of second guide layers 1311, wherein the plurality of second guide layers 1311 of the outer second guide member 13 are arranged at intervals along the axial direction of the outer second guide member 13, and the plurality of second guide layers 1311 of the inner second guide member 13 are arranged at intervals along the axial direction of the inner second guide member 13, and the outer second guide layer 1311 includes The first flow guide member 12 includes a plurality of second flow guide holes 13111 arranged at intervals along the circumference of the outer second flow guide member 13, the inner second flow guide layer 1311 includes a plurality of second flow guide holes 13111 arranged at intervals along the circumference of the inner second flow guide member 13, and along the axial and / or circumferential direction of the first flow guide member 12, at least partial areas of the plurality of second flow guide layers 1311 of the outer second flow guide member 13 are staggered with the corresponding second flow guide layers 1311 of the inner second flow guide member 13.

[0073] That is, along the axial direction of the first guide member 12, at least a portion of the second guide layers 1311 of the plurality of second guide layers 1311 of the outer second guide member 13 is staggered with the corresponding second guide layers 1311 of the inner second guide member 13, and the guide assembly 100 is continued in accordance with Figure 4 The placement direction shown in the figure is used as an example for explanation, assuming that the outer second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the outer second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the outer second guide member 13, and the inner second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the inner second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the inner second guide member 13. For example, the 6 second guide layers of the outer second guide member 13 1311, 4 second guide holes 13111 among the 8 second guide holes 13111 in one second guide layer 1311 may be partially staggered up and down with 8 second guide holes 13111 in any one second guide layer 1311 in the inner second guide member 13 in the height direction of the guide component 100, or 6 second guide layers 1311 in the outer second guide member 13 may be staggered up and down in sequence with 6 second guide layers 1311 in the inner second guide member 13 in the height direction of the guide component 100, which may be set specifically according to actual conditions, and will not be described one by one here; Alternatively, along the circumference of the first guide member 12, at least a portion of the second guide layers 1311 of the plurality of second guide layers 1311 of the outer second guide member 13 is staggered with the corresponding second guide layers 1311 of the inner second guide member 13, and the guide assembly 100 is continued in accordance with Figure 4The placement direction shown in the figure is used as an example for explanation, assuming that the outer second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the outer second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the outer second guide member 13, and the inner second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the inner second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the inner second guide member 13. For example, the 6 second guide layers 1311 of the outer second guide member 13 1, 4 second guide holes 13111 among 8 second guide holes 13111 in 1 second guide layer 1311 and 8 second guide holes 13111 in any second guide layer 1311 in the inner second guide member 13 may be partially circumferentially staggered, or the second guide holes 13111 in 6 second guide layers 1311 of the outer second guide member 13 and the second guide holes 13111 in 6 second guide layers 1311 in the inner second guide member 13 are all circumferentially staggered, which is specifically set according to actual conditions and will not be described one by one here; Alternatively, along the axial direction and the circumferential direction of the first guide member 12, at least a portion of the second guide layers 1311 of the plurality of second guide layers 1311 of the outer second guide member 13 is staggered with the corresponding second guide layers 1311 of the inner second guide member 13, and the guide assembly 100 is continued according to Figure 413. The arrangement direction shown in FIG. 1 is taken as an example to illustrate, assuming that the outer second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the outer second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the outer second guide member 13, and the inner second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the inner second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the inner second guide member 13. For example, in the height direction of the guide assembly 100 and along the circumference of the first guide member 12, the outer second guide member 13 includes 6 second guide layers 1311, each second guide layer 1311 of the inner second guide member 13 includes 8 second guide holes 13111 arranged at intervals along the circumference of the inner second guide member 13. Among the six second guide layers 1311 of the flow member 13, four second guide holes 13111 among the eight second guide holes 13111 in one second guide layer 1311 can be partially staggered with the second guide holes 13111 among the eight second guide holes 13111 in any second guide layer 1311 in the inner second guide member 13, or the second guide holes 13111 in the six second guide layers 1311 of the outer second guide member 13 and the second guide holes 13111 in the six second guide layers 1311 in the inner second guide member 13 are all staggered, which is specifically set according to actual conditions and will not be described one by one here. Such a setting ensures that the multiple second guide holes 13111 in the multiple second guide layers 1311 in the outer second guide member 13 are not completely opposite to the multiple second guide holes 13111 in the multiple second guide layers 1311 in the inner second guide member 13.

[0074] 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 guide space 16 through the second guide holes 13111 in the multiple second guide layers 1311 of the inner second guide member 13, and then part of the supercritical carbon dioxide in the second guide space 16 flows out from the second guide holes 13111 in the multiple second guide layers 1311 of the outer second guide member 13. Since the multiple second guide holes 13111 in the multiple second guide layers 1311 in the outer second guide member 13 are not completely opposite to the multiple second guide holes 13111 in the multiple second guide layers 1311 in the inner second guide member 13, the second guide holes 13111 staggered inside and outside further enhance the multi-layer deceleration effect of the guide structure 1, thereby facilitating further reducing the speed of the supercritical carbon dioxide flowing out of the second guide portion 131.

[0075] In some embodiments of the present application, the size of the inner second guide hole 13111 is greater than or equal to the size of the outer second guide hole 13111. In this way, combined with the staggered distribution of the outer second guide hole 13111 and the inner second guide hole 13111, a step-by-step diffusion effect can be formed, which can reduce the energy loss caused by turbulence while reducing the supercritical carbon dioxide injection speed.

[0076] In some embodiments of the present application, Figure 1 and Figure 6 As shown, the blocking structure 2 includes a blocking member 21 and a fixing member 22. The blocking member 21 is used to block the first through hole 111. The fixing member 22 is used to fix the blocking member 21 and the substrate 11. The fixing member 22 is configured to disconnect when the external pressure on the blocking member 21 is greater than the preset breaking force of the fixing member 22, so that the blocking member 21 is opened. In other words, when supercritical carbon dioxide is delivered to the first through hole 111 of the flow-guiding structure 1, the supercritical carbon dioxide in the first through hole 111 will apply external pressure to the blocking member 21 blocking the first through hole 111. If the fixing member 22 disconnects when the external pressure on the blocking member 21 is greater than the preset breaking force of the fixing member 22, the blocking member 21 is opened under the impact of the supercritical carbon dioxide, which meets the requirements of the blocking structure 2, and the structure is simple, reliable and low-cost.

[0077] In some embodiments of the present application, Figure 1 and Figure 6 As shown, it also includes: a guide member 3, the guide member 3 is fixed in the installation space 14, the guide member 3 has a guide hole 31 extending along the axial direction of the first guide member 12, the blocking member 21 has a guide rod 211 arranged corresponding to the guide hole 31, the guide rod 211 is penetrated by the guide hole 31 and is movable relative to the guide hole 31, and along the thickness direction of the guide member 3, the guide member 3 has a second through hole 32.

[0078] Specifically, when the blocking member 21 is opened under the impact of supercritical carbon dioxide, the guide rod 211 of the blocking member 21 moves upward along the guide hole 31 of the guide member 3. In this way, the guiding cooperation between the guide rod 211 and the guide hole 31 is conducive to improving the stability of the movement of the blocking member 21.

[0079] Furthermore, the inner circumferential surface of the first flow guide member 12 has a mounting boss, which is arranged around the circumference of the first flow guide member 12, and the mounting boss is formed with a fourth through hole along the axial direction of the first flow guide member 12, and the guide member 3 is fixed to the mounting boss so that the mounting boss and the guide member 3 jointly divide the mounting space 14 into a first sub-space and a second sub-space, and along the thickness direction of the guide member 3, the guide member 3 has a second through hole 32, and the first sub-space and the second sub-space are suitable for being connected through the second through hole 32, wherein 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 a partial area of ​​the second through hole 32 overlaps with the fourth through hole.

[0080] It can be understood that there may be a plurality of second through holes 32 , and the plurality of second through holes 32 are sequentially spaced apart along the circumferential direction of the guide member 3 .

[0081] When the blocking member 21 is opened, a large flow of high-pressure supercritical carbon dioxide enters the first subspace from the first through hole 111, wherein part of the supercritical carbon dioxide passes through the fourth through hole and the second through hole 32 from the first subspace in sequence into the second subspace, and then is ejected through the open end of the second subspace. With such a configuration, the guide member 3 can block part of the supercritical carbon dioxide flowing out of the first subspace, thereby helping to reduce the speed of the supercritical carbon dioxide flowing out from the open end of the installation space 14, and helping to further improve the drainage efficiency of the supercritical carbon dioxide.

[0082] In some embodiments of the present application, Figure 1 As shown, it also includes: a cover plate 4, which is fixed in the installation space 14, and 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, and 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 is connected with the outside through the third through hole 41.

[0083] Specifically, the outer circumferential surface of the cover plate 4 is assembled with the inner circumferential surface of the first guide member 12, and the cover plate 4 can be fixedly connected to the first 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 the cover plate 4 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 subspace is connected to the outside through the third through hole 41. In this way, when part of the supercritical carbon dioxide passes through the fourth through hole and the second through hole 32 from the first subspace in sequence to enter the second subspace, the supercritical carbon dioxide in the second subspace passes through the third through hole 41 of the cover plate 4 and is ejected outward, thereby further reducing the speed of the supercritical carbon dioxide flowing out from the open end of the installation space 14.
