Description

Technical Field

[0001] The present invention belongs to the technical field of refrigeration and heating, and more specifically, relates to a work recovery multi-cylinder refrigeration and heating device. Background Art

[0002] Space cooling is an important guarantee for people to maintain a high quality of life in modern times. In the existing technology, compressor refrigeration is mainly used. However, there are many problems with the refrigerants used in gas compression refrigerators. The refrigerants (such as chlorine- and bromine-containing refrigerants) are manufactured and released into the environment in large quantities, causing great damage to the environment.

[0003] In recent years, a technology using solid-state spring cards for cooling and heating has emerged. Solid-state spring card cooling and heating is a new green and environmentally friendly cooling and heating technology. By loading or unloading the solid-state spring card material, it causes phase change or reverse phase change to generate heat or cold, thereby cooling or heating, and then using heat transfer fluid to export the generated heat or cold.

[0004] However, the existing solid-state spring card refrigeration equipment is basically in the theoretical and experimental stages, and the cooling heating capacity is too small to meet the needs of practical applications; and when its cooling capacity increases to a certain level (such as 1 horsepower), due to the excessive stress exerted by the power mechanism on the spring card material, the power mechanism and other components may not be able to withstand excessive loads.

[0005] To solve the above problems, we plan to use a transmission device to connect multiple solid-state spring-cage heat regenerators in parallel, and use a group of power devices to drive the operation of multiple solid-state spring-cage heat regenerators.

[0026] The work recovery multi-cylinder refrigeration and heating device provided by the present invention is now described.

[0027] like Figure 1 and Figure 2As shown, the first embodiment of the present invention provides a work recovery multi-cylinder refrigeration and heating device, including a power mechanism 30, a multi-linkage transmission mechanism 20 and a plurality of solid-state spring-clip heat regenerators 10, the power mechanism 30 is used to output power; the multi-linkage transmission mechanism 20 has a power input end and a plurality of power output ends, the power input end is connected to the power mechanism 30; the plurality of solid-state spring-clip heat regenerators 10 are respectively connected to different power output ends of the multi-linkage transmission mechanism 20, so as to cool or heat under the drive of the power output end; wherein the multi-linkage transmission mechanism 20 includes a mounting bracket, an eccentric wheel rod 21 and a plurality of driving rods 23, the mounting bracket is relatively fixedly arranged with the solid-state spring-clip heat regenerator 10; the eccentric wheel rod 21 is rotatably arranged on the mounting bracket and connected to the power mechanism 30. A plurality of eccentric wheels 211 are arranged at intervals on the eccentric wheel rod 21, and the plurality of eccentric wheels 211 are arranged at a non-zero phase angle; a plurality of driving rods 23 are slidably arranged on the mounting bracket and are respectively arranged corresponding to the plurality of eccentric wheels 211. One end of each driving rod 23 is in contact with the corresponding eccentric wheel 211, and the other end is connected to one of the solid-state spring-clip heat regenerators 10, so that power is input to the solid-state spring-clip heat regenerator 10 under the drive of the eccentric wheel 211; wherein, the portion where the eccentric wheel rod 21 is connected to the power mechanism 30 is the power input end, and the portion where the driving rod 23 is connected to the solid-state spring-clip heat regenerator 10 is the power output end.

[0028] Specifically, the power mechanism 30 can be a motor, a hydraulic power element, a pneumatic power element, etc.

[0029] Compared with the prior art, the power recovery multi-cylinder refrigeration and heating device provided in this embodiment can use a set of power mechanisms 30 to drive multiple solid-state spring card heat regenerators 10 suitable for spring card materials to perform cooling or heating through a multi-link transmission mechanism 20. After that, the multiple solid-state spring card heat regenerators 10 are aggregated to obtain sufficient heating or cooling capacity to meet the needs of practical applications; and because the multiple eccentric wheels 211 on the eccentric wheel rod 21 are arranged at a non-zero phase angle, the multiple solid-state spring card heat regenerators 10 are in a Different loading processes, and the rebound force of the solid-state spring card heat regenerator 10 after loading is completed will be reversely transmitted back to the corresponding eccentric wheel 211 through the corresponding driving rod 23, and then transmitted to other eccentric wheels 211 through the eccentric wheel rod 21, for loading the corresponding solid-state spring card heat regenerator 10; in this way, the rebound work of the solid-state spring card heat regenerator 10 can be used again to load other solid-state spring card heat regenerators 10, which is beneficial to work recovery, thereby facilitating the power mechanism 30 to output power more stably and reduce energy loss.

[0030] like Figures 1 to 5 As shown, a specific implementation mode provided by the present invention based on the first implementation mode is as follows: To facilitate the extraction of cooling capacity or heating capacity, the work recovery multi-cylinder refrigeration and heating device also includes a heat transfer medium collection mechanism, which is respectively connected to multiple solid-state spring-clip heat regenerators 10 to supply heat transfer medium to the multiple solid-state spring-clip heat regenerators 10 respectively, and collects the heat transfer medium extracted after cooling or heating by the solid-state spring-clip heat regenerator 10 for heat exchange.

[0031] The heat transfer medium collection mechanism can be a piping system composed of components such as pipelines, busbars, distributors, pumping components, heat transfer medium storage components, etc. The heat transfer medium collection mechanism is connected to heat exchangers and other equipment that need to use heat or cold to form a cycle to achieve heat transfer and circulation.

[0032] The eccentric wheel rod 21 can be transmission connected to a power mechanism 30 at one end, or can be transmission connected to a power mechanism 30 at both ends. That is, power can be input using one power mechanism 30 or two power mechanisms 30 according to the needs of use, and the two power mechanisms 30 can be of the same power or type, or of different powers or types.

[0033] like Figure 5 As shown, the eccentric wheel 211 is a cylindrical structure integrally formed on the eccentric wheel rod 21. Reinforcement bodies 212 are provided at both ends of the eccentric wheel 211 to prevent the eccentric wheel 211 from breaking due to stress concentration at both ends. In a specific embodiment, the reinforcement body 212 is a crescent structure integrally formed on the eccentric wheel rod 21. The eccentric distance of the eccentric wheel 211 is consistent with the length of the compression of the pressure head in the corresponding solid-state spring card regenerator 10.

[0034] In order to ensure the stability of the eccentric rod 21 and reduce friction loss, the mounting bracket and the eccentric rod 21 are rotated together through a bearing 24, and a bearing 24 is provided between two adjacent eccentrics 211 to increase the force of the eccentric rod 21. The bearing 24 can be a bearing component such as a ball bearing, a spherical bearing, an air bearing, or other components that can play the role of a bearing.

[0035] There is a phase angle of 360 / n between adjacent eccentric wheels 211 on the eccentric wheel rod 21, where n is the number of eccentric wheels 211. In this way, when the eccentric wheel rod 21 rotates, the torque is roughly the same, so that different solid-state spring-clip heat regenerators 10 can operate in turn, which can not only ensure the stability of the structure and power output, but also reduce the shaking of the eccentric wheel rod 21, never reduce mechanical wear and noise, and can also reduce friction loss and improve energy utilization.

[0036] An end of the driving rod 23 facing the eccentric wheel 211 is provided with a wear-resistant block 231 to reduce wear.

[0037] like Figure 8As shown, in some specific embodiments, the solid-state spring card heat regenerator 10 includes a fixed sleeve 11, a plurality of solid-state spring card material plates 12, a pressure head 13, a plug structure 14 and a medium conveying pipeline assembly, a barrel cavity is provided in the fixed sleeve 11, a plurality of solid-state spring card material plates 12 are stacked in the barrel cavity of the fixed sleeve 11, and each solid-state spring card material plate 12 includes a perforation, and a plurality of perforations are stacked to form a flow cavity for the passage of a heat-conducting medium; the pressure head 13 is slidably disposed at one end of the fixed sleeve 11 and is connected to a driving rod 23, so as to load or unload the plurality of solid-state spring card material plates 12 driven by the driving rod 23, so that the plurality of solid-state spring card material plates 12 are deformed to generate heat or cool; the plug structure 14 is blocked at the other end of the fixed sleeve 11 and abuts against the solid-state spring card material plate 12, so as to limit the axial movement of the solid-state spring card material plate 12; the medium conveying pipeline assembly is connected to the flow cavity for the input and output of the heat-conducting medium.

[0038] It should be noted that the shape of the pressure head 13 is the same as the cross-sectional shape of the solid spring card material plate. In this way, when the pressure head applies stress to the solid spring card material plate, it can avoid applying force to the protrusion at the same time, thereby increasing the energy consumption ratio of the cooling and heating device. In order to increase the strength of the loading, the pressure head can be set to high-strength ceramic or tungsten steel.

[0039] The shape and number of the perforations can be selected as required. Preferably, the perforations are polygonal, radial, circular or square.

[0040] In a specific embodiment, the solid spring card material plate 12 is plate-shaped. Since each plate is independently stressed, during the loading and unloading process, even if cracks appear in some solid spring card materials, only the solid spring card material plate 12 where it is located will fail, and the cracks will not spread to other solid spring card material plates, that is, it will not cause the overall failure of the solid spring card material to affect the overall work, thereby improving the service life of the solid spring card material. In addition, after the plate-shaped solid spring card material plates 12 are stacked, the damage to the material of the present application caused by the loading force will be greatly reduced during the loading process, avoiding the buckling deformation of the material.

[0041] In a specific embodiment, the thickness of the solid spring material plate is 0.01-100 mm, preferably 0.1-10 mm, and more preferably 0.44-0.3 mm.

[0042] In practical applications, in order to prevent the solid-state spring-loaded material plates 12 from being misaligned or the perforations from being unable to align to form a smooth flow cavity after being stacked during use, a limiting structure can be set between the solid-state spring-loaded material plates 12 and the fixed sleeve 11 to limit the rotation between the solid-state spring-loaded material plates 12 and the fixed sleeve 11.

[0043] The limiting structure can be a limiting structure formed by the shape between the solid spring-loaded material plate 12 and the fixed sleeve 11, or an interference fit relationship between the solid spring-loaded material plate 12 and the fixed sleeve 11, or a limiting member separately arranged in the fixed sleeve 11.

[0044] In one embodiment, the inner wall of the fixed sleeve 11 is clamped with the solid-state spring-cage material plate, that is, the inner wall shape of the fixed sleeve 11 is set to be the same as the shape of the solid-state spring-cage material plate and there is a gap or the solid-state spring-cage material plate is inscribed with the inner wall of the fixed sleeve 11. For example, the inner wall shape of the fixed sleeve 11 and the shape of the solid-state spring-cage material plate can be set to be irregular shapes, polygons, squares, etc., which contain angles and can be mutually clamped and are not easy to rotate. In the embodiment of the present invention, the inner wall shape of the fixed sleeve 11 and the shape of the solid-state spring-cage material plate are preferably hexagonal. In some embodiments, the solid-state spring-cage material plate can also be inscribed with the inner wall of the fixed sleeve 11. Preferably, the inner wall of the fixed sleeve 11 is circular or has an arc-shaped inner angle, and the solid-state spring-cage material plate is square or polygonal for easy inscription. For example, the inner wall of the fixed sleeve 11 is circular, the solid-state spring-cage material plate is square, and the square inscribes a circle; the inner wall of the fixed sleeve 11 is a rectangle with a right angle of an arc, and the solid-state spring-cage material plate is a rectangle or a hexagon.

[0045] In order to fix the position of the stacked solid-state spring-cage material plates, the fixed sleeve 11 may also be provided with a limiter to limit the movement of the solid-state spring-cage material plates. For example, a protrusion is radially provided along the inner wall of the fixed sleeve 11, and a recess is provided at the edge of the solid-state spring-cage material plate, so that the protrusion of the fixed sleeve 11 extends into the recess of the stacked solid-state spring-cage material plate to limit the position. In another embodiment, the stacked solid-state spring-cage material plates are fixed with a limiter and then fixed with the fixed sleeve 11. For example, a rod-shaped limiter is inserted into the flow cavity of the stacked solid-state spring-cage material plates, and the rod-shaped object is fixed with the fixed sleeve 11 by a fixing device.

[0046] like Figure 6 As shown, in a specific embodiment, each solid spring-loaded material plate 12 includes a groove, and a space formed by stacking a plurality of grooves is used to accommodate a protrusion 113 on the inner wall of the fixed sleeve 11. After the protrusion 113 extends into the space formed by the stacked grooves, the gap between the inner wall of the fixed sleeve 11 and the outer surface of the stacked solid spring-loaded material plates 12 forms an additional flow cavity for the heat transfer fluid to flow.

[0047] In practical applications, the larger the mass or volume of the solid-state spring card material, the more heat or cold it generates. Therefore, in order to maximize the absorption of the heat or cold generated by the solid-state spring card material by the medium, this embodiment also needs to ensure that the amount of the solid-state spring card material matches the heat transfer capacity. Generally, a larger flow cavity size is designed to ensure that the same mass of solid-state spring card material has a larger specific surface area or volume.

[0048] The grooves of each solid-state spring card material plate correspond to the protrusions 113 on the inner wall of the fixed sleeve 11 in multiple and one-to-one correspondence. The number of protrusions 113 on the inner wall of the fixed sleeve 11 is the same as the number of groove spaces formed after the solid-state spring card material plates 12 are stacked, and the protrusions 113 are respectively embedded in the groove spaces of the solid-state spring card material plates 12. In this embodiment, the protrusions 12 extend longitudinally along the fixed sleeve 11, and their length is greater than or equal to the length of the solid-state spring card material plates 12 after stacking. In this way, the position of the solid-state spring card material plate 12 can be fixed to a certain extent to limit its dislocation. In order to increase the cross-sectional area of ​​the flow cavity, multiple protrusions 113 and grooves can be set at different angles. In order to further increase the flow cavity, a serrated structure can also be set at the edge of the groove of the solid-state spring card material plate 12 to form a small micro-flow cavity while increasing the contact area between the heat transfer fluid and the solid-state spring card material, thereby increasing the heat transfer efficiency.

[0049] The grooves and protrusions can be rectangular, arc-shaped, or irregular in shape, which is not limited here. Preferably, the grooves and protrusions can be designed to be rectangular. The flow cavity formed in this way is an elongated structure. On the one hand, the contact surface with the solid spring card material is large. On the other hand, due to the obstruction of the protrusions, the flow rate of the heat transfer fluid is faster and the heat transfer efficiency is higher.

[0050] The gap between the inner wall of the fixed sleeve 11 and the edge of the groove of the solid spring material plate 12 is 0.1-5 mm, preferably 0.5-1 mm. Under this size, the flow resistance can be minimized and the flow velocity can be maximized.

[0051] In practical applications, if there is a gap between the inner wall of the fixed sleeve 11 and the solid spring-cage material plate, the solid spring-cage material plate may be slightly misaligned, causing the perforations on its surface to be difficult to align, affecting the flow rate of the heat transfer fluid in the flow cavity. To solve this problem, the invention provides an embodiment, in which the outer surface of the protrusion contacts the inner surface of the stacked groove, that is, only the protrusion and the groove are clamped without leaving a gap, so that a gap is left between the inner wall of the fixed sleeve 11 and the outer edge of the solid spring-cage material plate, thereby limiting the misalignment of the solid spring-cage material plate.

[0052] It should be noted that the solid-state spring card material plate will expand in the lateral direction during the loading process. Therefore, in order to ensure that there is enough space for the solid-state spring card material plate when expanding, a gap is left between the solid-state spring card material plate and the inner wall shape of the fixed sleeve 11. In some applications, a partition is set on the inner wall of the fixed sleeve 11, for example, a partition film is brushed or attached to the inner wall of the fixed sleeve 11. The partition film can be Teflon, POM, nylon, polyester or silicone. On the one hand, the film is soft and can play a role in accommodating and buffering when the solid-state spring card material plate expands. On the other hand, the film has a heat-insulating effect, which minimizes the heat loss when the medium exchanges heat through the flow cavity. In addition, when the inner wall of the fixed sleeve 11 and the solid-state spring card material plate are connected by clamping, the partition can also clamp the solid-state spring card material plate well. In practical applications, Teflon is preferably used. In order to facilitate assembly, brushing is used. After brushing the Teflon paint on the inner wall of the fixed sleeve 11, the solid-state spring card material plate is placed in the tube cavity of the fixed sleeve 11, which is easy to operate. The thickness of the solid spring card material plate is 0.01-100 mm, preferably 0.1-10 mm, and more preferably 0.44-0.3 mm.

[0053] In the embodiment of the present invention, a plurality of perforations are provided on the solid spring-cage material plate, and after the solid spring-cage material plates are stacked, the perforations are aligned to form a flow cavity. In the embodiment where the solid spring-cage material plate is connected to the inner wall of the fixed sleeve 11, the edge of the solid spring-cage material plate and the inner wall of the fixed sleeve 11 form a second flow cavity. In this embodiment, the shape and number of the perforations are not limited. Preferably, the perforations are polygonal, radial, circular or square. Figure 3 As shown, the solid-state ejection card unit also includes: a plug body, which is inserted into the flow cavity formed by the perforation, so that the plug body is connected with the inner wall of the perforation to form a plurality of micro-flow cavities.

[0054] In practical applications, in order to increase the heat transfer efficiency of the medium, the present embodiment designs the perforation to be polygonal, radial, circular or square, and inserts a plug body therein, so that the plug body and the inner wall of the perforation form a microfluidic cavity, which can greatly increase the flow rate of the medium, reduce the flow resistance, and increase the heat transfer efficiency. On the other hand, since the larger the volume (mass or volume) of the solid spring card material, the more heat or cold it generates, therefore, in order to maximize the absorption of the heat or cold generated by the solid spring card material by the medium, the present embodiment also needs to ensure that the amount of the solid spring card material matches the heat transfer capacity. Under normal circumstances, designing a larger perforation size can ensure that the solid spring card material of the same mass has a larger specific surface area or volume. The present embodiment adopts a design of large-sized perforations and plug bodies, which can reduce the flow resistance and increase the flow rate compared to a large number of small-sized perforations, so that the medium can absorb the heat generated by the solid spring card material to the maximum extent and improve the heat transfer efficiency. In an optional embodiment, the plug body can be used as a limiter to fix the position of the solid spring card material plate and limit its movement and dislocation.

[0055] like Figure 6 As shown, the fixed sleeve 11 includes a first half-cylinder 111, a second half-cylinder 112 and a fixed sleeve longitudinal seal. The first half-cylinder 111 is provided with a first half-groove inside; the second half-cylinder 112 is provided with a second half-groove inside, and is buckled with the first half-cylinder 111 through a positioning structure, so that the first half-groove and the second half-groove form the above-mentioned cylinder cavity for accommodating multiple solid spring material plates 12; the fixed sleeve longitudinal seal is provided between the first half-cylinder 111 and the second half-cylinder 112, and is used to seal the joint between the first half-cylinder 111 and the second half-cylinder 112.

[0056] This form can facilitate the installation and replacement of the solid spring material plate 12, while also ensuring the strength of the entire structure. In addition, the specific heat capacity of the fixed sleeve 11 can be selected according to its material for heat preservation.

[0057] It should be noted that the fixing sleeve 11 is preferably made of a polymer material, specifically nylon, polyester, hard silicone, resin, etc., preferably polytetrafluoroethylene. During the process of stress loading of the driving mechanism 3, the solid cooling and heating plate 12 will expand laterally. The use of a polymer material can accommodate its expanded size and buffer the lateral pressure. On the other hand, the polymer material has weak thermal conductivity and can also prevent the heat loss of the heat transfer fluid.

[0058] In a specific embodiment, the positioning structure between the first half cylinder 111 and the second half cylinder 112 can be a structure in which a protrusion and a groove cooperate, or it can be a hole or groove structure positioned by fasteners or positioning pins, so as to facilitate the positioning and alignment of the first half cylinder 111 and the second half cylinder 112.

[0059] The barrel cavity can be a hollow cavity in the shape of a cylinder, a cube, a cuboid, etc., and its inner wall is in close contact with the solid cooling and heating plate 12, so that during the assembly process, the solid cooling and heating plate 12 can be placed in the fixed sleeve 11. The specific fixing method of the fixed sleeve 11 to the solid cooling and heating plate 12 can be selected as needed.

[0060] Specifically, Figure 3As shown, in a specific embodiment, the pressure head 13 includes a dynamic pressure head 131, a dynamic pressure head seal, a hydraulic pressure head 132 and a driving pressure head 133. The dynamic pressure head 131 is slidably arranged in the cylinder cavity and abuts against the solid spring-card material plate 12. The dynamic pressure head 131 is provided with a first flow hole connected to the flow cavity; the dynamic pressure head seal is arranged between the dynamic pressure head 131 and the inner wall of the cylinder cavity for sealing; the hydraulic pressure head 132 is connected to one end of the dynamic pressure head 131 facing away from the solid spring-card material plate 12, and is provided with a second flow hole and a plurality of liquid separation holes, the second flow hole is connected to the first flow hole, and the plurality of liquid separation holes are all connected to the second flow hole at one end, and the other end is connected and communicated with the medium conveying pipeline assembly; the driving pressure head 133 is slidably arranged in the sleeve 44, and is connected to the hydraulic pressure head 132, and is connected to the driving rod 23 to transmit power.

[0061] Preferably, the cross-sectional shape of the end of the dynamic pressure head 131 in contact with the solid-state cooling and heating plate 12 is the same, and the first flow hole is located at the center of the dynamic pressure head 131 and is coaxial with the cavity. In this embodiment, the dynamic pressure head 131 has the same cross-sectional shape as the end of the solid-state cooling and heating plate 12 that applies stress and completely covers the cross-sectional shape of the solid-state cooling and heating plate, which can ensure that the solid-state cooling and heating plate completely undergoes a phase change when stress is applied, thereby improving the efficiency of cooling and heating. In addition, setting the first flow hole at the center of the dynamic pressure head 131 can ensure that the heat transfer fluid in the cavity at all angles is uniform and flows out of the first flow hole at the same flow rate.

[0062] In order to increase the strength of the loading, the dynamic pressure head 131 can be set to high-strength tungsten steel.

[0063] The dynamic pressure head 131 is a T-shaped cross-section structure; the first flow hole includes a plurality of micropores, the second flow hole includes a micropore section and a collection section, the micropore section is connected to the micropores to facilitate the circulation of the heat transfer medium; the plug structure 14 is provided with a third flow hole, the bottom sealing plate 43 is provided with a fourth flow hole, the third flow hole also includes a micropore section and a collection section, the micropore section is connected to the flow cavity, and the collection section is connected to the fourth flow hole. In this way, the heat transfer medium can be easily led out from both ends of the solid-state spring card heat regenerator 10, thereby improving the circulation efficiency of the heat transfer medium.

[0064] like Figure 1 , Figure 2 and Figure 8As shown, the work recovery multi-cylinder refrigeration and heating device also includes an outer shell 40, and the outer shell cover is arranged on the outside of the solid-state spring-clip heat regenerator 10. The outer shell 40 includes a first outer shell body 41, a limiting end plate 42 and a bottom sealing plate 43. A plurality of cavities are provided inside the first outer shell body 41, and the cavities are used to accommodate the solid-state spring-clip heat regenerator 10; the limiting end plate 42 is provided at one end of the first outer shell body 41 facing the multi-linkage transmission mechanism 20, and is used to limit the solid-state spring-clip heat regenerator 10, and a through hole for the power output end of the multi-linkage transmission mechanism 20 to pass through is provided at the position of the limiting end plate 42 corresponding to the cavity; the bottom sealing plate 43 is provided at one end of the first outer shell body 41 facing away from the multi-linkage transmission mechanism 20, and is detachably connected to the first outer shell body 41, and is connected to the end of the solid-state spring-clip heat regenerator 10.

[0065] During assembly, the multi-linkage transmission mechanism 20 can be connected to one end of the first outer shell 41, and the solid-state spring-clip heat regenerator 10 can be installed into the corresponding tube cavity from the other end of the first outer shell 41, and firmly fixed by the limiting end plate 42 and the bottom sealing plate 43, so that the multiple multi-linkage transmission mechanisms 20 become a whole, the installation process is also simple and convenient, and the multi-linkage transmission mechanism 20 can stably load and unload the solid-state spring-clip heat regenerator 10, thereby ensuring the stability of the equipment operation.

[0066] like Figure 1 As shown, the housing 40 further includes a second housing 45 , which is connected to the first housing 41 , the multi-linkage transmission mechanism 20 is disposed in the second housing 45 , the power mechanism 30 is disposed on the housing 40 , and one end of the eccentric wheel rod 21 passes through the housing 40 .

[0067] The multi-linkage transmission mechanism 20 further includes a compensating transmission assembly, which is disposed between the power mechanism 30 and the eccentric wheel rod 21 to perform compensating transmission. The compensating transmission assembly can be a transmission assembly capable of distance compensation, such as a gear transmission assembly or a chain transmission assembly.

[0068] like Figure 8 As shown, in some embodiments, the housing 40 further includes a sleeve 44, which is fixed in the first housing body 41 to form a lumen. The sleeve 44 can be interference-fitted with the fixed sleeve 11 to perform constraint.

[0069] Furthermore, in order to reduce friction and improve the movement accuracy of the dynamic pressure head 131, a slide rail is provided in the sleeve 44, and the driving pressure head 133 slides with the sleeve 44 through the slide rail so that the driving pressure head 133 slides along the slide rail during loading or unloading.

[0070] In some embodiments, the slide rail in the inner wall of the sleeve 44 that contacts the fixed sleeve 11 can be provided with a clamping piece for fixing the fixed sleeve 11, or the slide rail may not be provided in the portion of the inner wall of the sleeve 44 that overlaps with the fixed sleeve 11, and only the guide rail may be provided at the port of the sleeve 44.

[0071] In practical applications, the assembled fixing sleeve 11 and the pressure head 13 are placed in the sleeve 44, which not only fixes the various mechanisms, but also facilitates the replacement of the components therein.

[0072] like Figures 2 to 5 As shown, the multi-linkage transmission mechanism 20 includes a mounting bracket, an eccentric wheel rod 21 and a plurality of driving rods 23. The mounting bracket is fixedly arranged relative to the solid-state spring-clip heat regenerator 10; the eccentric wheel rod 21 is rotatably arranged on the mounting bracket and connected to the power mechanism 30, and a plurality of eccentric wheels 211 are arranged at intervals on the eccentric wheel rod 21; the plurality of driving rods 23 are slidably arranged on the mounting bracket and are respectively arranged corresponding to the plurality of eccentric wheels 211, and one end of each driving rod 23 is in conflict with the corresponding eccentric wheel 211, and the other end is connected to one of the solid-state spring-clip heat regenerators 10, so that power is input to the solid-state spring-clip heat regenerator 10 under the drive of the eccentric wheel 211.

[0073] Through this structure, the rotational power of the eccentric wheel rod 21 can be converted into the tension and compression power on the driving rod, so as to input power into the solid-state spring card heat regenerator 10. By compressing the spring card material in the solid-state spring card heat regenerator 10, it undergoes phase change and releases heat during compression, and then recovers the phase change and absorbs heat after unloading.

[0074] An end of the driving rod 23 facing the eccentric wheel 211 is provided with a wear-resistant block 231 to reduce wear.

[0075] The driving rod 25 and the pressure head 13 may be connected by a pin, but the pin connection is prone to breakage due to large bearing capacity and long-term wear. Figures 6 to 8 As shown, a pressing head 232 is provided at one end of the driving rod 25 ; the pressing head 13 is provided with a bearing groove 134 , and the pressing head 232 can be pressed against the bottom of the bearing groove 134 to transmit the pressing power to the pressing head 13 through the driving rod 25 .

[0076] Through the cooperation between the top pressure head 232 of the driving rod 25 and the bearing groove 134 on the pressure head 13, the top pressure power on the driving rod 25 can be effectively transmitted to the pressure head 13, and then the solid-state spring-cage heat regenerator 10 is loaded through the pressure head 13; since this structure does not have components such as pins, it will not break or fail under conditions of large load-bearing capacity and long-term wear, so stable power transmission can be achieved; at the same time, since the solid-state spring-cage heat regenerator 10 will have a rebound force when unloading, and the pressure head 13 and the driving rod 25 can be reset under the action of the rebound force, this form will not affect the continuous operation of the equipment.

[0077] The gap between the ram 232 and the mouth of the socket 134 has a swing margin to allow the drive rod 25 to swing during the ram power transmission process, thereby avoiding wear and splitting of the socket 134.

[0078] The top pressure head 232 is an arc-shaped convex structure, and the bottom of the receiving groove 134 is an arc-shaped concave structure that matches the top pressure head 232, thereby improving the transmission effect of the top pressure power.

[0079] like Figure 7 As shown, a blind hole 135 is provided at the bottom of the receiving groove 134. The blind hole 135 can, on the one hand, accommodate foreign matter such as iron filings and sand particles generated during operation or accidentally entering the receiving groove 134, so as to prevent these foreign matter from affecting power transmission; on the other hand, since the gas or liquid in the blind hole 135 is discharged during the pressing process, the blind hole 135 can also play the role of a negative pressure suction cup, so that a certain adhesion can be generated between the driving rod 25 and the pressure head 13, which is conducive to the coordinated movement between the two.

[0080] Grease is filled between the top pressure head 232 and the bearing groove 134. This can not only reduce the mechanical wear of the top pressure head 232 and the bearing groove 134, but also reduce the possibility of foreign matter intrusion affecting power transmission, and at the same time can enhance the effect of the negative pressure suction cup to facilitate the coordinated movement between the driving rod 25 and the pressure head 13.

[0081] There may be a plurality of blind holes 135 arranged at intervals, so that the aperture of each blind hole 135 can be small enough to avoid affecting the shape of the bottom of the socket 134, thereby ensuring stable power transmission.

[0082] like Figure 8 As shown, a wear-resistant sleeve 233 is provided on the top pressure head 232 to reduce the wear of the driving rod 25, and a pressure sensor 234 is provided between the top pressure head 232 and the wear-resistant sleeve 233 to detect the pressure between the driving rod 25 and the pressure head 13, so as to determine whether the power transmission is within the required range, and then adjust the driving rod 25 or the pressure head 13 according to the result.

[0083] Specifically, the power mechanism 30 may be a power component such as a reduction motor or an internal combustion engine that can output rotational power.

[0084] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
