[0046] As shown in Figure 1 , Figure 2 and Figure 8 , the present application provides an easy-to-assemble multi-cylinder refrigeration and heating device, comprising a power mechanism 30, a multi-link transmission mechanism 20, a plurality of solid-state elastic card heat regenerators 10 and an outer shell 40.

The outer shell 40 is arranged outside the plurality of solid-state elastic card heat regenerators 10. The outer shell 40 comprises a first outer shell body 41, a limiting end plate 42 and a bottom sealing plate 43. The first outer shell body 41 is internally provided with a plurality of tube cavities for accommodating the solid-state elastic card heat regenerators 10. The limiting end plate 42 is arranged at one end of the first outer shell body 41 facing the multi-link transmission mechanism 20, and is used to limit the solid-state elastic card heat regenerators 10. The limiting end plate 42 is provided with through holes corresponding to the tube cavities for the power output ends of the multi-link transmission mechanism 20 to pass through. The bottom sealing plate 43 is arranged at the other end of the first outer shell body 41 away from the multi-link transmission mechanism 20, and is detachably connected with the first outer shell body 41 and connected with the end portions of the solid-state elastic card heat regenerators 10.

[0047] Specifically, the power mechanism 30 can be an electric motor, a hydraulic power element, a pneumatic power element, etc.

[0048] Compared with the prior art, the easily-assembled multi-cylinder refrigeration and heating device provided by the embodiment can use a set of power mechanism 30 to drive multiple solid-state elastic card regenerators 10 suitable for elastic card materials to perform refrigeration or heating, and then the multiple solid-state elastic card regenerators 10 are gathered together to obtain sufficient heating or refrigeration capacity to meet the requirements in actual applications. When assembling, the multi-cylinder transmission mechanism 20 can be connected to one end of the first shell body 41, and the solid-state elastic card regenerators 10 can be loaded into the corresponding pipe cavities from the other end of the first shell body 41, and the limiting end plate 42 and the bottom sealing plate 43 are used to fix the solid-state elastic card regenerators 10 firmly, so that the multiple multi-cylinder transmission mechanisms 20 become a whole, the installation process is simple and convenient, and the multi-cylinder transmission mechanism 20 can stably load and unload the solid-state elastic card regenerators 10, thereby ensuring the stability of the equipment operation.

[0049] As shown in Figures 1 to 5 , the utility model discloses a kind of specific implementation modes based on the first embodiment as follows:

[0050] To facilitate the export of refrigeration capacity or heating capacity, the easily-assembled multi-cylinder refrigeration and heating device further comprises a heat-conducting medium collection mechanism, which is connected to the multiple solid-state elastic card regenerators 10 respectively to supply heat-conducting medium to the multiple solid-state elastic card regenerators 10 respectively, and to collect and exchange heat with the heat-conducting medium exported after refrigeration or heating by the solid-state elastic card regenerators 10.

[0051] The heat-conducting medium collection mechanism can be a piping system composed of pipes, busbars, distributors, pumping components, heat-conducting medium storage components, etc. The heat-conducting medium collection mechanism is connected to equipment requiring heat or cold, such as heat exchangers, to form a circulation to realize heat transfer and circulation.

[0052] As shown in Figure 1 , the shell 40 further comprises a second shell body 45, the second shell body 45 is connected to the first shell body 41, the multi-cylinder transmission mechanism 20 is arranged in the second shell body 45, the power mechanism 30 is arranged on the shell 40, and one end of the eccentric wheel rod 21 penetrates out of the shell 40.

[0053] The multi-cylinder transmission mechanism 20 further comprises a compensation transmission component arranged between the power mechanism 30 and the eccentric wheel rod 21 to perform compensation transmission. The compensation transmission component can be a gear transmission component or a chain transmission component, etc. which can perform distance compensation.

[0054] As shown in Figures 2 to 5As shown, the multi-link transmission mechanism 20 includes a mounting bracket, an eccentric rod 21 and a plurality of driving rods 23. The mounting bracket is fixedly arranged opposite to the solid spring snap regenerator 10. The eccentric rod 21 is rotationally arranged on the mounting bracket and connected with the power mechanism 30. A plurality of eccentric wheels 211 are arranged on the eccentric rod 21 at intervals. The plurality of driving rods 23 are slidingly arranged on the mounting bracket and correspondingly arranged with the plurality of eccentric wheels 211. Each driving rod 23 is in abutment with the corresponding eccentric wheel 211 at one end and connected with one of the solid spring snap regenerators 10 at the other end, so as to input power to the solid spring snap regenerator 10 under the driving of the eccentric wheel 211. The part where the eccentric rod 21 is connected with the power mechanism 30 is the power input end, and the part where the driving rod 23 is connected with the solid spring snap regenerator 10 is the power output end.

[0055] Through the structure, the rotation power of the eccentric rod 21 can be converted into the pulling and pressing power on the driving rod, so as to input power to the solid spring snap regenerator 10, compress the spring snap material in the solid spring snap regenerator 10 to cause phase change and release heat, and unload the phase change to absorb heat.

[0056] The eccentric rod 21 can be connected with one power mechanism 30 at one end, or connected with one power mechanism 30 at each end. That is, one power mechanism 30 can be used to input power according to the use requirement, or two power mechanisms 30 can be used to input power. The two power mechanisms 30 can be of the same power or type, or of different power or type.

[0057] The phase angle between the adjacent eccentric wheels 211 on the eccentric rod 21 is 360 / n, where n is the number of the eccentric wheels 211. In this way, the torque is substantially the same when the eccentric rod 21 rotates, so that the different solid spring snap regenerators 10 are operated in turn, which can ensure the stability of the structure and power output, reduce the swing of the eccentric rod 21, reduce the mechanical wear and noise, reduce the friction loss, and improve the energy utilization rate.

[0058] The end of the driving rod 23 towards the eccentric wheel 211 is provided with a wear-resistant block 231 to reduce wear.

[0059] The eccentric wheel 211 is a cylindrical structure integrally formed on the eccentric rod 21. The eccentric wheel 211 is provided with a reinforcing body 212 at both ends to avoid fracture due to stress concentration at both ends of the eccentric wheel 211. In one specific embodiment, the reinforcing body 212 is a crescent structure integrally formed on the eccentric rod 21. The eccentric distance of the eccentric wheel 211 is consistent with the length of the pressure head compression in the corresponding solid spring snap regenerator 10.

[0060] To ensure the stability of the eccentric rod 21 while reducing the friction loss, the rotating fit is formed between the mounting bracket and the eccentric rod 21 through the bearing 24, and the bearing 24 is arranged between two adjacent eccentric wheels 211 to increase the stress of the eccentric rod 21. The bearing 24 can be a ball bearing, a ball bearing, an air bearing, or other bearing components that can function as a bearing.

[0061] The driving rod 25 and the pressure head 13 can be connected by a pin shaft, but the pin shaft connection will be more prone to breakage under the action of large bearing capacity and long-term wear. Therefore, in some embodiments, as shown in Figures 6 to 8 The driving rod 25 is provided with a pressing head 232 at one end; the pressure head 13 is provided with a bearing groove 134, and the pressing head 232 can be pressed on the bottom of the bearing groove 134 to transmit the pressing force to the pressure head 13 through the driving rod 25.

[0062] Through the cooperation between the pressing head 232 of the driving rod 25 and the bearing groove 134 on the pressure head 13, the pressing force on the driving rod 25 can be effectively transmitted to the pressure head 13, and then the solid-state elastic spring regenerator 10 is loaded through the pressure head 13; Since this structure does not have components such as pin shafts, it will not break down under the working conditions of large bearing capacity and long-term wear, so it can realize stable transmission of power; At the same time, the solid-state elastic spring regenerator 10 will have a rebound force when it is unloaded, and the pressure head 13 and the driving rod 25 can be reset under the action of the rebound force, so this form will not affect the continuous operation of the equipment.

[0063] The gap between the pressing head 232 and the mouth of the bearing groove 134 has a swing allowance to allow the driving rod 25 to swing during the transmission of the pressing force, thereby avoiding wear and splitting of the bearing groove 134.

[0064] The pressing head 232 is an arc-shaped convex structure, and the bottom of the bearing groove 134 is an arc-shaped concave structure matched with the pressing head 232, thereby improving the transmission effect of the pressing force.

[0065] As shown in Figure 7 The bottom of the bearing groove 134 is provided with a blind hole 135. The blind hole 135 can accommodate iron filings, sand particles and other foreign matters generated or accidentally entering the bearing groove 134 during operation, thereby avoiding the influence of these foreign matters on power transmission; On the other hand, due to the discharge of gas or liquid in the blind hole 135 during the pressing process, the blind hole 135 also functions as a negative pressure suction cup, so that the driving rod 25 and the pressure head 13 can be adhered to a certain extent, which is beneficial to the cooperative movement between them.

[0066] The grease is filled between the top pressure head 232 and the bearing groove 134. In this way, not only the mechanical wear of the top pressure head 232 and the bearing groove 134 can be reduced, but also the possibility of foreign matter invading to affect the power transmission can be reduced, and the action of the negative pressure suction cup is beneficial to the cooperative movement between the driving rod 25 and the pressure head 13.

[0067] The blind holes 135 can be arranged in multiple intervals, so that the aperture of each blind hole 135 can be small enough to avoid affecting the shape of the bottom of the bearing groove 134, thereby ensuring the stability of power transmission.

[0068] As shown in Figure 8 The wear-resistant sleeve 233 is arranged on the top pressure head 232 to reduce the wear of the driving rod 25, and the pressure sensor 234 is arranged 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.

[0069] As shown in Figure 8 In some specific embodiments, the solid-state elastic snapback heater 10 includes a fixed sleeve 11, a plurality of solid-state elastic snapback material plates 12, a pressure head 13, a plug structure 14, and a medium conveying pipeline assembly. One end of the fixed sleeve 11 abuts against the limiting end plate 42. The plurality of solid-state elastic snapback material plates 12 are stacked in the fixed sleeve 11, and each solid-state elastic snapback material plate 12 contains a perforation. The plurality of perforations are stacked to form a flow cavity for the heat-conducting medium to pass through. The pressure head 13 is slidingly arranged at one end of the fixed sleeve 11 facing the limiting end plate 42 and is connected with the driving rod 23, so as to load or unload the plurality of solid-state elastic snapback material plates 12 under the driving of the driving rod 23, so that the plurality of solid-state elastic snapback material plates 12 are deformed to generate heat or cold. The plug structure 14 is plugged at one end of the fixed sleeve 11 away from the limiting end plate 42 and abuts against the solid-state elastic snapback material plate 12, so as to limit the axial movement of the solid-state elastic snapback material plate 12. The plug structure 14 is connected with the bottom sealing plate 43. The medium conveying pipeline assembly is in communication with the flow cavity for the input and output of the heat-conducting medium.

[0070] It should be noted that the shape of the pressure head 13 is the same as the cross-sectional shape of the solid-state elastic snapback material plate. In this way, when the pressure head applies stress to the solid-state elastic snapback material plate, the force acting on the protrusion can be avoided, and the energy consumption ratio of the refrigeration and heating device can be increased. In order to increase the loading strength, the pressure head can be made of high-strength ceramic or tungsten steel.

[0071] The shape and number of the perforations can be selected as needed. Preferably, the perforations are polygons, radial, circular or square.

[0072] In a specific embodiment, the solid elastic material plate 12 is plate-shaped, and since each plate is independently stressed, even if some solid elastic material cracks during loading and unloading, only the solid elastic material plate 12 where the crack occurs is invalid, and the crack does not spread to other solid elastic material plates, i.e., the solid elastic material as a whole is not invalid and does not affect the overall work, thereby improving the service life of the solid elastic material.

[0073] In a specific embodiment, the thickness of the solid elastic material plate is 0.01-100 mm, preferably 0.1-10 mm, and more preferably 0.15-0.3 mm.

[0074] In actual applications, in order to avoid misalignment or perforation of the solid elastic material plate 12 after stacking in the use process, the solid elastic material plate 12 and the fixed sleeve 11 can be provided with a limiting structure for limiting the rotation between the solid elastic material plate 12 and the fixed sleeve 11.

[0075] The limiting structure can be a limiting structure formed by the shapes of the solid elastic material plate 12 and the fixed sleeve 11, or an interference fit relationship between the solid elastic material plate 12 and the fixed sleeve 11, or a limiting member separately provided in the fixed sleeve 11.

[0076] In an embodiment, the inner wall of the fixed sleeve 11 is clamped with the solid elastic material plate, i.e., the shape of the inner wall of the fixed sleeve 11 is the same as that of the solid elastic material plate and there is a gap or the solid elastic material plate internally fits the inner wall of the fixed sleeve 11. For example, the shape of the inner wall of the fixed sleeve 11 and the shape of the solid elastic material plate can be irregular polygons, polygons, squares, etc. containing angles, which can be clamped with each other and are not easy to rotate. In the embodiment of the present application, the shape of the inner wall of the fixed sleeve 11 and the shape of the solid elastic material plate are preferably hexagonal. In some embodiments, the solid elastic material plate can also internally fit the inner wall of the fixed sleeve 11. Preferably, the inner wall of the fixed sleeve 11 is circular or the inner angle is arc-shaped, and the solid elastic material plate is square or polygonal to facilitate internal fitting. For example, the inner wall of the fixed sleeve 11 is circular, and the solid elastic material plate is square, and the square internally fits the circle; the inner wall of the fixed sleeve 11 is a rectangle with a right angle that is arc-shaped, and the solid elastic material plate is a rectangle or a hexagon.

[0077] To fix the position of the stacked solid spring-loaded card material plates, the fixing sleeve 11 can also be provided with a limiting member to restrict the movement of the solid spring-loaded card material plates. For example, a protrusion is provided radially along the inner wall of the fixing sleeve 11, and a recess is provided at the edge of the solid spring-loaded card material plate, so that the protrusion of the fixing sleeve 11 extends into the recess of the stacked solid spring-loaded card material plate for limiting. In another embodiment, the stacked solid spring-loaded card material plates are fixed with the limiting member before being fixed to the fixing sleeve 11. For example, a rod-shaped limiting member is inserted into the flow cavity of the stacked solid spring-loaded card material plate, and then the rod-shaped member is fixed to the fixing sleeve 11 by a fixing device.

[0078] like Figure 6 As shown, in one specific embodiment, each solid spring clip material plate 12 includes a groove, and the space formed by stacking multiple grooves is used to accommodate the protrusion 113 on the inner wall of the fixing sleeve 11. After the protrusion 113 extends into the space formed by the stacked grooves, the gap between the inner wall of the fixing sleeve 11 and the outer surface of the stacked solid spring clip material plate 12 forms an additional flow cavity for the flow of heat-conducting fluid.

[0079] In practical applications, the larger the mass or volume of the solid cartridge material, the more heat or cold it generates. Therefore, in order to maximize the absorption of the heat or cold generated by the solid cartridge material by the medium, this embodiment also needs to ensure that the amount of solid cartridge material matches the heat transfer capacity. Generally, designing a larger flow cavity size can ensure that the same mass of solid cartridge material has a larger specific surface area or volume.

[0080] Each solid spring-loaded material plate has multiple grooves corresponding to the protrusions 113 on the inner wall of the fixing sleeve 11. The number of protrusions 113 on the inner wall of the fixing sleeve 11 is the same as the number of groove spaces formed after the solid spring-loaded material plates 12 are stacked, and the protrusions 113 are respectively embedded in the groove spaces of the solid spring-loaded material plates 12. In this embodiment, the protrusions 12 extend longitudinally along the fixing sleeve 11, and their length is greater than or equal to the length of the solid spring-loaded material plates 12 after stacking. In this way, the position of the solid spring-loaded material plates 12 can be fixed to a certain extent, limiting their misalignment. In order to increase the cross-sectional area of ​​the flow cavity, multiple protrusions 113 and grooves can be arranged at different angles. In order to further increase the flow cavity, a serrated structure can also be provided on the edge of the groove of the solid spring-loaded material plate 12 to form a small microfluidic cavity and increase the contact area between the heat-conducting fluid and the solid spring-loaded material, thereby increasing the heat conduction efficiency.

[0081] The grooves and protrusions can be rectangular, arc-shaped, or irregular shapes, and are not limited here. Preferably, the grooves and protrusions can be designed as rectangles, so that the flow cavity formed is a slender structure. On the one hand, the contact surface with the solid elastic material is large, and on the other hand, due to the obstruction of the protrusions, the flow rate of the heat-conducting fluid is faster, and the heat transfer efficiency is higher.

[0082] The gap between the inner wall of the fixed sleeve 11 and the groove edge of the solid elastic clamping material plate 12 is 0.1-5mm, preferably 0.5-1mm, at which size the flow resistance is minimized and the flow rate is maximized.

[0083] In actual application, if there is a gap between the inner wall of the fixed sleeve 11 and the solid elastic clamping material plate, the solid elastic clamping material plate may be slightly misaligned, which makes the perforations on the surface of the solid elastic clamping material plate not easy to align, affecting the flow rate of the heat-conducting fluid in the flow cavity. To solve this problem, the utility model provides an embodiment in which the convex outer surface is in contact with the inner surface of the stacked grooves, that is, only the convex and the groove are clamped without leaving a gap, so that a gap is left between the outer edge of the solid elastic clamping material plate and the inner wall of the fixed sleeve 11, thereby limiting the misalignment of the solid elastic clamping material plate.

[0084] It should be noted that the solid elastic clamping material plate will expand in the transverse direction during loading, therefore, in order to ensure that the solid elastic clamping material plate has enough space to expand, a gap is left between the solid elastic clamping material plate and the inner wall of the fixed sleeve 11. In some applications, a partition is provided on the inner wall of the fixed sleeve 11, for example, a partition film is coated or attached on the inner wall of the fixed sleeve 11, which can be Teflon, POM, nylon, polyester or silicone. On the one hand, the soft film can accommodate and buffer the expansion of the solid elastic clamping material plate, on the other hand, the film has a heat-insulating effect, which can minimize heat loss when the medium exchanges heat through the flow cavity. In addition, when the fixed sleeve 11 and the solid elastic clamping material plate are clamped, the partition can also clasp the solid elastic clamping material plate well. In actual application, Teflon is preferred, and in order to facilitate assembly, Teflon paint is brushed on the inner wall of the fixed sleeve 11, and then the solid elastic clamping material plate is placed in the lumen of the fixed sleeve 11, which is convenient to operate. The thickness of the solid elastic clamping material plate is 0.01-100mm, preferably 0.1-10mm, and more preferably 0.15-0.3mm.

[0085] In the embodiment of the utility model, a plurality of perforations are provided on the solid elastic clamping material plate, and the perforations are aligned to form a flow cavity after the solid elastic clamping material plates are stacked. In the embodiment in which the inner wall of the fixed sleeve 11 is fixed in the solid elastic clamping material plate, the edge of the solid elastic clamping material plate and the inner wall of the fixed sleeve 11 form a second flow cavity. In this embodiment, the shape and number of perforations are not limited. Preferably, the perforations are polygonal, radial, circular or square. As shown in the figure, the solid elastic clamping unit further comprises a plug body, which is inserted into the flow cavity formed by the perforations, so that the plug body and the inner wall of the perforations form a plurality of micro-flow cavities. Figure 3

[0086] ​In practical applications, in order to increase the heat transfer efficiency of the medium, the perforations in the embodiment are designed in polygonal, radial, circular or square shapes, and a plug is inserted therein, so that the plug and the inner wall of the perforation form a micro-flow cavity. On the one hand, the flow rate of the medium can be greatly increased, the flow resistance can be reduced, and the heat transfer efficiency can be increased. On the other hand, the greater the volume (mass or volume) of the solid elastic clamping material, the more heat or cold it will generate. Therefore, in order to maximize the heat or cold generated by the solid elastic clamping material to be absorbed by the medium, the amount of the solid elastic clamping material needs to be matched with the heat transfer capacity in the embodiment. Generally, a larger perforation size can ensure that the solid elastic clamping material of the same mass has a larger specific surface area or volume. The design of the large-size perforation with the plug in the embodiment can reduce the flow resistance and increase the flow rate, so that the medium can maximize the absorption of the heat generated by the solid elastic clamping material and improve the heat transfer efficiency. In an optional embodiment, the plug can be used as a limiting piece to fix the position of the solid elastic clamping material plate and limit its movement and misplacement.

[0087] As shown in Figure 8 , in some embodiments, the shell 40 further comprises a sleeve 44 fixedly arranged in the first shell body 41 to form a tube cavity. The sleeve 44 can be in interference fit with the fixing sleeve 11 to constrain it.

[0088] 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.

[0089] As shown in Figure 6 , the fixing sleeve 11 comprises a first half cylinder 111, a second half cylinder 112 and a fixing sleeve longitudinal seal. The first half cylinder 111 is internally provided with a first half groove; the second half cylinder 112 is internally provided with a second half groove 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 a cylinder cavity for accommodating a plurality of solid elastic clamping material plates 12; and the fixing sleeve longitudinal seal is arranged between the first half cylinder 111 and the second half cylinder 112 to seal the joint between the first half cylinder 111 and the second half cylinder 112.

[0090] In this form, the installation and replacement of the solid elastic clamping material plates 12 can be facilitated, and the overall strength of the structure can also be ensured. In addition, the specific heat capacity of the fixing sleeve 11 can be selected according to its material in order to keep warm.

[0091] It should be noted that the fixed sleeve 11 is preferably made of a high polymer material, which can be nylon, polyester, hard silica gel, resin, etc., and is preferably made of polytetrafluoroethylene. During the stress loading process of the driving mechanism 3, the solid-state refrigeration and heating plate 12 will expand laterally. Using a high polymer material can accommodate the expanded size and buffer the lateral pressure. On the other hand, the high polymer material has poor thermal conductivity, which can also prevent the heat loss of the heat-conducting fluid.

[0092] In a specific embodiment, the positioning structure between the first half cylinder 111 and the second half cylinder 112 can be a structure of protrusions and grooves, or a hole or slot structure positioned by fasteners or positioning pins, etc., to facilitate the positioning and alignment of the first half cylinder 111 and the second half cylinder 112.

[0093] The cylinder cavity can be a cylindrical, square, rectangular, etc. shaped cavity, and its inner wall is in close contact with the solid-state refrigeration and heating plate 12. Thus, during assembly, the solid-state refrigeration and heating plate 12 can be placed in the fixed sleeve 11. The specific fixing method of the fixed sleeve 11 to the solid-state refrigeration and heating plate 12 can be selected as needed.

[0094] Specifically, as shown in Figure 3 In a specific embodiment, the pressure head 13 includes a moving pressure head 131, a moving pressure head seal, a liquid guide pressure head 132, and a driving pressure head 133. The moving pressure head 131 is slidingly arranged in the cylinder cavity and abuts against the solid-state elastic material plate 12. The moving pressure head 131 is provided with a first flow hole communicating with the flow cavity. The moving pressure head seal is arranged between the moving pressure head 131 and the inner wall of the cylinder cavity for sealing. The liquid guide pressure head 132 is connected to the end of the moving pressure head 131 away from the solid-state elastic material plate 12 and is provided with a second flow hole and a plurality of liquid distribution holes. The second flow hole communicates with the first flow hole, and the plurality of liquid distribution holes communicate with the second flow hole at one end and are connected to and communicate with the medium conveying pipeline assembly at the other end. The driving pressure head 133 is slidingly arranged in the sleeve 44 and is connected to the liquid guide pressure head 132 and the driving rod 23 to transmit power.

[0095] Preferably, the cross-sectional shape of the end of the moving pressure head 131 in contact with the solid-state refrigeration and heating plate 12 is the same as that of the first flow hole located at the center of the moving pressure head 131 and coaxial with the cavity. In this embodiment, the cross-sectional shape of the end of the moving pressure head 131 in contact with the solid-state refrigeration and heating plate 12 is the same as that of the solid-state refrigeration and heating plate, which can ensure that the solid-state refrigeration and heating plate completely changes phase when stress is applied, thereby improving the efficiency of refrigeration and heating. In addition, by arranging the first flow hole at the center of the moving pressure head 131, the heat-conducting fluid in the cavity at each angle can be uniformly distributed at the same flow rate and flow out of the first flow hole.

[0096] In order to increase the loading strength, the moving pressure head 131 can be made of high-strength tungsten steel.

[0097] The dynamic pressure head 131 is a T-shaped cross-section structure; the first flow hole comprises a plurality of micro-holes, the second flow hole comprises a micro-hole section and a collection section, the micro-hole section is communicated with the micro-holes to facilitate the flow of the heat conducting 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 comprises a micro-hole section and a collection section, the micro-hole section is communicated with the flow cavity, and the collection section is communicated with the fourth flow hole. In this way, the heat conducting medium can be conveniently led out from both ends of the solid elastic spring regenerator 10, so that the circulation efficiency of the heat conducting medium is improved.

[0098] Further, in order to reduce friction and improve the movement accuracy of the dynamic pressure head 131, a slide rail is arranged in the sleeve 44, and the driving pressure head 133 is slidably connected with the sleeve 44 through the slide rail, so that the driving pressure head 133 slides along the slide rail when loading or unloading.

[0099] In some embodiments, the slide rail in the inner wall of the sleeve 44 which is in contact with the fixed sleeve 11 can be provided with a clamping piece for fixing the fixed sleeve 11, or the part of the inner wall of the sleeve 44 which overlaps with the fixed sleeve 11 can not be provided with a slide rail, and only a guide rail is arranged at the port of the sleeve 44.

[0100] Specifically, the power mechanism 30 can be a reduction motor or an internal combustion engine, etc. which can output rotating power.

[0101] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
