[0002] This application belongs to the field of refrigeration and heating technology, and more specifically, relates to a refrigeration and heating device. Background Technology

[0003] Space cooling is an important guarantee for people to maintain a high quality of life in modern times. In the current technology, compressor refrigeration is mainly used. However, the refrigerants used in gas compression refrigeration machines have many problems. Their refrigerants (such as chlorine- and bromine-containing refrigerants) are manufactured in large quantities and released into the environment, causing great damage to the environment.

[0004] In recent years, a technology utilizing solid-state cartridge cooling and heating has emerged. Solid-state cartridge cooling and heating technology is an emerging green and environmentally friendly cooling and heating technology. By loading or unloading solid-state cartridge materials, a phase change or reverse phase change occurs, generating heat or cold energy, which is then used for cooling or heating. Afterward, a heat-conducting fluid is used to remove the generated heat or cold energy.

[0005] However, most existing solid-state cartridge cooling and heating equipment is currently in the theoretical and experimental stages, and its cooling and heating capacity is too small to meet the needs of practical applications. When its cooling capacity increases to a certain level (such as 1 horsepower), the power mechanism and other components may not be able to withstand the excessive load due to the excessive stress applied to the cartridge material by the power mechanism. Technical issues

[0052] The refrigeration and heating device provided in this application will now be described.

[0053] As shown in Figures 1 and 2, the first embodiment of this application provides a cooling and heating device, including a power mechanism 30, a multi-linkage transmission mechanism 20, and multiple solid spring-loaded regenerators 10. The power mechanism 30 is used to output power; the multi-linkage transmission mechanism 20 has a power input end and multiple power output ends, and the power input end is connected to the power mechanism 30; the multiple solid spring-loaded regenerators 10 are respectively connected to different power output ends on the multi-linkage transmission mechanism 20, so as to cool or heat under the drive of the power output ends.

[0054] Specifically, the power mechanism 30 can be an electric motor, a hydraulic power component, a pneumatic power component, etc.

[0055] Compared with the prior art, the cooling and heating device provided in this application embodiment can use a set of power mechanisms 30 to drive multiple solid spring-loaded card regenerators 10 suitable for the operation of spring-loaded card materials to perform cooling or heating through a multi-linkage transmission mechanism 20. After that, the multiple solid spring-loaded card regenerators 10 are combined to obtain a sufficient amount of heating or cooling capacity. This can avoid the problem of the material being unable to bear the load due to the solid spring-loaded card regenerators 10 being designed too large, and can provide a sufficient amount of heating or cooling capacity to meet the needs of practical applications.

[0056] As shown in Figures 1 to 12, this application provides a further specific implementation method based on the first implementation method as follows:

[0057] To facilitate the export of cooling or heating capacity, the cooling and heating device also includes a heat transfer medium collection mechanism. The heat transfer medium collection mechanism is connected to multiple solid spring-loaded regenerators 10 to supply heat transfer medium to the multiple solid spring-loaded regenerators 10 respectively, and collects the heat transfer medium exported after cooling or heating by the solid spring-loaded regenerators 10 for heat exchange.

[0058] A heat transfer medium collection mechanism can be a piping system composed of components such as pipes, manifolds, distributors, pumping components, and heat transfer medium storage components. The heat transfer medium collection mechanism connects to heat exchangers and other equipment that require heat or cold to form a circulation loop, achieving heat transfer and circulation.

[0059] As shown in Figures 2 and 3, in some specific embodiments, the multi-linkage transmission mechanism 20 includes a rotating main shaft 21 and multiple power output sections. The rotating main shaft 21 is connected to the power mechanism 30; the multiple power output sections are spaced apart on the rotating main shaft 21 and are respectively connected to the corresponding solid-state spring-loaded regenerators 10. In this way, the power mechanism 30 can input power to the rotating main shaft 21, and the power can be input to the corresponding solid-state spring-loaded regenerators 10 through the multiple power output sections; wherein, the part of the rotating main shaft 21 connected to the power mechanism is the power input end, and the part of the power output section connected to the solid-state spring-loaded regenerator 10 is the power output end.

[0060] The rotating spindle 21 can be connected to a power mechanism 30 at one end or to a power mechanism 30 at both ends. That is, power can be input by one power mechanism 30 or by two power mechanisms 30, depending on the needs of use. The two power mechanisms 30 can be of the same power or type or of different power or type.

[0061] In order to limit the position of the rotating spindle 21, the multi-linkage transmission mechanism 20 also includes a spindle support 26. The spindle support 26 is fixed on a stable working surface and is relatively fixed to the solid spring-loaded regenerator 10. That is, the positions of the two are relatively fixed and are rotatably connected to the rotating spindle 21 to ensure the stable rotation of the rotating spindle 21, reduce the shaking of the rotating spindle 21, and prevent the power on the rotating spindle 21 from not being transmitted to the solid spring-loaded regenerator 10.

[0062] To ensure the stability of the rotating spindle 21 when outputting power to the power output section and generating excessive load, and to reduce frictional losses, the rotating spindle 21 is connected to the spindle support 26 by multiple second bearings, with the second bearings located between adjacent power output sections. The position of these second bearings can be referenced from that of the second bearing 29 in another embodiment shown in Figure 13.

[0063] The rotating spindle 21 and the power output section can be mechanisms such as crank-connecting rod structures or cam structures that meet the usage requirements.

[0064] Specifically, as shown in Figures 3 and 8, in some specific embodiments, the power output section includes an eccentric cam 23, a first bearing 22, a ring 24, and a drive rod 25. The eccentric cam 23 is fixed on the rotating main shaft 21; the first bearing 22 is sleeved on the outer ring of the eccentric cam 23; the ring 24 is clamped outside the first bearing 22; one end of the drive rod 25 is fixedly connected to the ring 24, and the other end is connected to the solid spring regenerator 10.

[0065] With this structure, the rotational power of the rotating spindle 21 can be converted into the tension and compression power on the drive rod 25, so as to input power into the solid spring card regenerator 10. By compressing the spring card material in the solid spring card regenerator 10, it causes a phase change and releases heat, and unloading the phase change restores heat absorption. The friction between the eccentric cam 23 and the ring 24 can be reduced by the first bearing 22.

[0066] The first bearing 22 and the second bearing can be bearing components such as ball bearings, ball bearings, air bearings, or other components that can function as bearings.

[0067] In one specific embodiment, the first bearing 22 is a ball bearing, capable of withstanding a load of 100,000 N, and the second bearing is a ball bearing, capable of withstanding a load of 46,713 N. In practical applications, when this cooling and heating device is used in practice, for example in an air conditioner, for an air conditioner with an energy consumption of 1 horsepower (734 W), the energy efficiency ratio (COP) = cooling capacity / power consumed. Calculated with a COP of 3-3.5, the cooling power of this device is approximately 2400 W. Based on the characteristics of this solid spring material, the pressure during phase change is 900,000,000 Pa, so the pressure output by a single power output section is approximately 45,000 N. In this embodiment, using a ball bearing as the first bearing 22 can maximize the load-bearing capacity, while using a ball bearing as the second bearing can ensure the stability of the rotating spindle 21.

[0068] Furthermore, the eccentric cam 23 has a disc-shaped wheel structure and an eccentric shaft hole inside. The shaft hole has an inner keyway, and the rotating spindle 21 has an outer keyway at the corresponding part of each eccentric cam 23. The eccentric cam 23 and the rotating spindle 21 are fixedly connected by a key strip that is locked between the inner keyway and the outer keyway to ensure the stability of the structure.

[0069] The adjacent external keyways on the rotating spindle 21 have a phase angle of 360 / n, meaning that all external keyways are evenly distributed on the lateral projection of the rotating spindle 21, where n is the number of power output sections. This ensures that the torque is approximately the same when the rotating spindle 21 rotates, allowing different solid-state spring-loaded regenerators 10 to operate in turn. This guarantees structural and power output stability, reduces the wobbling of the rotating spindle 21, minimizes mechanical wear and noise, reduces frictional losses, and improves energy utilization.

[0070] As shown in Figures 3 and 8, in some specific embodiments, the hoop 24 includes a first half-ring 241, a second half-ring 242, and a half-ring fastener 243. The first half-ring 241 is fixedly connected to the drive rod 25 by means of threaded connection, welding, or integral molding. The second half-ring 242 is engaged with the first half-ring 241 and surrounds the outer ring of the first bearing 22. The half-ring fastener 243 is connected to the first half-ring 241 and the second half-ring 242 respectively to fasten the first half-ring 241 and the second half-ring 242 to the outer ring of the first bearing 22, so as to avoid relative movement between the hoop 24 and the outer ring of the first bearing 22, which would lead to problems such as power loss. The inner sides of the first half-ring 241 and the second half-ring 242 are provided with receiving grooves for accommodating the outer ring of the first bearing 22, so as to fasten the first half-ring 241 and the second half-ring 242 to the outer ring of the first bearing 22 by the half-ring fastener 243, so as to avoid the outer ring of the first bearing 22 from contacting the hoop 24.

[0071] Specifically, the semi-ring fastener 243 can be a threaded fastener, a snap fastener, or a pin fastener, etc.

[0072] Furthermore, the eccentric cam 23 and the inner ring of the first bearing 22 are interference-fitted to avoid relative movement between the eccentric cam 23 and the inner ring of the first bearing 22, which could lead to power loss and other problems.

[0073] As shown in Figures 3 to 7, in some specific embodiments, the solid spring-loaded regenerator 10 includes a fixed sleeve 11, multiple solid spring-loaded material plates 12, a pressure head 13, a plug structure 14, and a medium conveying pipeline assembly. Multiple solid spring-loaded material plates 12 are stacked within the fixed sleeve 11, and each solid spring-loaded material plate 12 includes a perforation 121. The multiple perforations 121, when stacked, 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 connected to a drive rod 25, used to load or unload the multiple solid spring-loaded material plates 12 under the drive of the drive rod 25, causing the multiple solid spring-loaded material plates 12 to deform, thereby generating heat or cooling. The plug structure 14 plugs the other end of the fixed sleeve 11 and abuts against the solid spring-loaded material plates 12, used to limit the axial movement of the solid spring-loaded material plates 12. The medium conveying pipeline assembly communicates with the flow cavity and the heat-conducting medium collection mechanism, and is connected to the heat-conducting medium collection mechanism for the input and output of the heat-conducting medium.

[0074] It should be noted that the shape of the pressure head 13 is the same as the cross-sectional shape of the solid spring plate 12. Thus, when the pressure head applies stress to the solid spring plate 12, it avoids simultaneously applying force to the protrusion, thereby increasing the energy efficiency of the cooling and heating device. To increase the strength of the load, the pressure head 13 can be made of high-strength ceramic or tungsten steel.

[0075] The shape and number of perforations 121 can be selected as needed. Preferably, the perforations 121 are polygonal, radial, or circular, etc., wherein the polygonal shape can be triangular, square, pentagonal, etc.

[0076] The drive rod 25 and the pressure head 13 can be connected by a pin, but the pin connection is prone to breakage under high load and long-term wear. Therefore, in some embodiments, as shown in Figures 9 to 11, one end of the drive rod 25 is provided with a pressure head 251; the pressure head 13 is provided with a bearing groove 134, and the pressure head 251 can press against the bottom of the bearing groove 134 to transmit pressing power to the pressure head 13 through the drive rod 25.

[0077] Through the cooperation between the top pressure head 251 of the drive rod 25 and the bearing groove 134 on the pressure head 13, the top pressure power on the drive rod 25 can be effectively transmitted to the pressure head 13, and then the solid spring-loaded regenerator 10 is loaded through the pressure head 13. Since this structure has no pins or other components, it will not break or fail under high load and long-term wear conditions, thus achieving stable power transmission. At the same time, since the solid spring-loaded regenerator 10 has a rebound force when unloading, the pressure head 13 and drive rod 25 can be reset under the action of the rebound force, so this form will not affect the continuous operation of the equipment.

[0078] The gap between the top pressure head 251 and the opening of the bearing groove 134 has a swing margin to allow the drive rod 25 to swing during the transmission of top pressure power, thereby avoiding wear and splitting of the bearing groove 134.

[0079] The top pressure head 251 has an arc-shaped convex structure, and the bottom of the bearing groove 134 has an arc-shaped concave structure that cooperates with the top pressure head 251, thereby improving the transmission effect of the top pressure force.

[0080] As shown in Figure 9, a blind hole 135 is provided at the bottom of the support groove 134. The blind hole 135 serves two purposes: firstly, it can accommodate foreign objects such as iron filings and sand particles that are generated during operation or accidentally enter the support groove 134, preventing these foreign objects from affecting power transmission; secondly, since the gas or liquid in the blind hole 135 is discharged during the pressing process, the blind hole 135 can also act as a negative pressure suction cup, allowing a certain degree of adhesion to be generated between the drive rod 25 and the pressure head 13, which is beneficial to the coordinated movement between the two.

[0081] Lubricating grease is filled between the pressure head 251 and the bearing groove 134. This not only reduces the mechanical wear of the pressure head 251 and the bearing groove 134, but also reduces the possibility of foreign objects intruding and affecting power transmission. At the same time, it enhances the effect of the negative pressure suction cup, which is beneficial to the coordinated movement between the drive rod 25 and the pressure head 13.

[0082] Multiple blind holes 135 can be spaced out so that the diameter of each blind hole 135 is small enough to avoid affecting the shape of the bottom of the bearing groove 134, thereby ensuring the stability of power transmission.

[0083] As shown in Figures 10 and 11, a wear-resistant sleeve 252 is provided on the top pressure head 251 to reduce the wear of the drive rod 25. A pressure sensor 253 is provided between the top pressure head 251 and the wear-resistant sleeve 252 to detect the pressure between the drive rod 25 and the pressure head 13, thereby determining whether the power transmission is within the required range, and then adjusting the drive rod 25 or the pressure head 13 according to the result.

[0084] Specifically, the top pressure head 251 is matched with the driving pressure head 133 in the pressure head 13, and the bearing groove 134 is specifically set on the driving pressure head 133.

[0085] In one specific embodiment, the solid spring clip material plate 12 is plate-shaped. Since each plate is independently stressed, even if some solid spring clip materials crack during loading and unloading, only the solid spring clip material plate 12 in which it appears will fail. The cracks will not spread to other solid spring clip material plates 12, that is, the overall failure of the solid spring clip material will not affect the overall operation, thereby improving the service life of the solid spring clip material. In addition, the stacked plate-shaped solid spring clip material plates 12 greatly reduce the damage of the loading force to the material itself during loading, avoiding buckling deformation of the material.

[0086] In one specific embodiment, the thickness of the solid spring clip material plate 12 is 0.01-100mm, specifically 0.01mm, 50.005mm, 100mm, etc., preferably 0.1-10mm, specifically 0.1mm, 5.05mm, 10mm, etc., more preferably 0.15-0.3mm, specifically 0.15mm, 0.225mm, 0.3mm, etc.

[0087] In practical applications, in order to prevent the solid spring clip material plates 12 from being misaligned or the perforations 121 from failing to align and form a smooth flow cavity during use, a limiting structure can be set between the solid spring clip material plates 12 and the fixed sleeve 11 to restrict the rotation between the solid spring clip material plates 12 and the fixed sleeve 11.

[0088] The limiting structure can be a limiting structure formed by the shape between the solid spring clip material plate 12 and the fixed sleeve 11, or it can be an interference fit between the solid spring clip material plate 12 and the fixed sleeve 11, or it can be a limiting component set separately in the fixed sleeve 11.

[0089] In one embodiment, the inner wall of the fixing sleeve 11 is engaged with the solid spring clip material plate 12. That is, the inner wall of the fixing sleeve 11 is shaped the same as the solid spring clip material plate 12 and there is a gap, or the solid spring clip material plate 12 is internally connected to the inner wall of the fixing sleeve 11. For example, the inner wall of the fixing sleeve 11 and the solid spring clip material plate 12 can both be irregular shapes or polygons, such as squares, containing corners, so that they can be interlocked and are not easily rotated. In this embodiment, the inner wall of the fixing sleeve 11 and the solid spring clip material plate 12 are preferably hexagonal. In some embodiments, the solid spring clip material plate 12 can also be internally connected to the inner wall of the fixing sleeve 11. Preferably, the inner wall of the fixing sleeve 11 is circular or has rounded inner corners, and the solid spring clip material plate 12 is polygonal to facilitate internal connection. For example, the inner wall of the fixing sleeve 11 is circular, and the solid spring clip material plate 12 is square with a circle inside the square; the inner wall of the fixing sleeve 11 is a rectangle with right angles in the shape of arcs, and the solid spring clip material plate 12 is a rectangle or hexagon.

[0090] To fix the position of the stacked solid spring-loaded card material plates 12, the fixing sleeve 11 can also be provided with a limiting member to restrict the movement of the solid spring-loaded card material plates 12. 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 12, so that the protrusion of the fixing sleeve 11 extends into the recess of the stacked solid spring-loaded card material plate 12 for limiting. In another embodiment, the stacked solid spring-loaded card material plates 12 are fixed with the limiting member before being fixed with 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 12, and then the rod-shaped limiting member is fixed to the fixing sleeve 11 by a fixing device.

[0091] As shown in Figures 5 to 7, in one specific embodiment, each solid spring clip material plate 12 includes a groove 122. The space formed by stacking multiple grooves 122 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 122, 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.

[0092] 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 heat-conducting 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.

[0093] Each solid spring-loaded material plate 12 has multiple grooves 122 corresponding to multiple 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 grooves 122 formed after the solid spring-loaded material plates 12 are stacked, and multiple protrusions 113 are respectively embedded in the grooves 122 of the solid spring-loaded material plate 12. In this embodiment, the protrusions 113 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 plate 12 can be fixed to a certain extent, limiting its misalignment. In order to increase the cross-sectional area of ​​the flow cavity, multiple protrusions 113 and multiple grooves 122 can be arranged at different angles. In order to further increase the size of the flow cavity, a serrated structure can also be provided on the edge of the groove 122 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.

[0094] The groove 122 and the protrusion 113 can be regular shapes such as rectangles and arcs or other irregular shapes, which are not limited here. Preferably, the groove 122 and the protrusion 113 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 protrusion 113, the flow rate of the heat-conducting fluid is faster and the heat transfer efficiency is higher.

[0095] The gap between the inner wall of the fixed sleeve 11 and the edge of the groove 122 of the solid spring clip material plate 12 is 0.1-5mm, specifically 0.1mm, 1.0mm, 2.0mm, 2.55mm, 3.0mm, 4.0mm, 5mm, etc., preferably 0.5-1mm, specifically 0.5mm, 0.75mm, 1.0mm, etc. Under this size, the flow resistance can be minimized and the flow velocity maximized.

[0096] In practical applications, if there are gaps between the inner wall of the fixing sleeve 11 and the solid spring clip material plate 12, the solid spring clip material plate 12 may be slightly misaligned, making it difficult to align the perforations 121 on its surface, thus affecting the flow rate of the heat-conducting fluid in the flow cavity. To solve this problem, this application provides an embodiment in which the outer surface of the protrusion 113 contacts the inner surface of the stacked groove 122, that is, only the protrusion 113 and the groove 122 are locked together without gaps, so that there are gaps between the inner wall of the fixing sleeve 11 and the outer edge of the solid spring clip material plate 12, thereby limiting the misalignment of the solid spring clip material plate 12.

[0097] It should be noted that the solid spring clip material plate 12 expands laterally during loading. Therefore, to ensure sufficient space for expansion, a gap is left between the solid spring clip material plate 12 and the inner wall of the fixing sleeve 11. In some applications, a partition is provided on the inner wall of the fixing sleeve 11. For example, a partition film can be coated or adhered to the inner wall of the fixing sleeve 11. This partition film can be made of Teflon, POM (polyformaldehyde), nylon, polyester, or silicone. On the one hand, the partition film is soft and can accommodate and buffer the expansion of the solid spring clip material plate 12. On the other hand, the partition film has a heat insulation function, minimizing heat loss when the heat-conducting medium exchanges heat through the flow cavity. In addition, when the inner wall of the fixing sleeve 11 and the solid spring clip material plate 12 are snapped together, the partition film can also effectively hold the solid spring clip material plate 12 in place. In practical applications, Teflon is preferred. For ease of assembly, it can be applied by brushing. After brushing the Teflon coating onto the inner wall of the fixing sleeve 11, the solid spring clip material plate 12 is placed into the cavity of the fixing sleeve 11, which is convenient. The thickness of the solid spring clip material plate 12 is 0.01-100mm, specifically 0.01mm, 50.005mm, 100mm, etc., preferably 0.1-10mm, specifically 0.1mm, 5.05mm, 10mm, etc., more preferably 0.15-0.3mm, specifically 0.15mm, 0.225mm, 0.3mm, etc.

[0098] In this embodiment, multiple perforations 121 are provided on the solid spring card material plate 12. After stacking multiple solid spring card material plates 12, the perforations 121 are aligned to form a flow cavity. In an embodiment where the solid spring card material plate 12 is connected to the inner wall of the fixing sleeve 11, a second flow cavity is formed between the edge of the solid spring card material plate 12 and the inner wall of the fixing sleeve 11. In this embodiment, the shape and number of perforations 121 are not limited. Preferably, the perforations 121 are regular or irregular shapes such as polygons, radial shapes, or circles. Polygons can be triangles, squares, rectangles, pentagons, etc. The solid spring card regenerator 10 also includes a plug body, which is inserted into the flow cavity formed by the perforations 121, so that the plug body is connected to the inner wall of the perforations 121 to form multiple microflow cavities.

[0099] In practical applications, to increase the heat transfer efficiency of the heat-conducting medium, this embodiment designs the perforations 121 as polygonal, radial, or circular, and inserts plugs into them, so that the plugs and the inner wall of the perforations 121 form microfluidic cavities. On the one hand, this can greatly increase the flow rate of the heat-conducting medium, reduce flow resistance, and increase 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, this embodiment also needs to ensure that the amount of solid spring card material and its heat transfer capacity are matched in order to maximize the absorption of the heat or cold generated by the solid spring card material by the heat-conducting medium. Generally, designing a larger perforation size can ensure that the same mass of solid spring card material has a larger specific surface area or volume. The design of large-sized perforations 121 with plugs in this embodiment can reduce flow resistance and increase flow rate compared to a larger number of small-sized perforations 121, so that the heat-conducting medium can absorb the heat generated by the solid spring card material to the maximum extent and improve heat transfer efficiency. In an optional embodiment, the plugs can be used as limiting members to fix the position of the solid spring card material plate 12 and restrict its movement and misalignment.

[0100] As shown in Figures 3, 4 and 6, in some embodiments, the solid spring-loaded regenerator 10 further includes an outer sleeve 15, which is sleeved outside the fixed sleeve 11 and is interference-fitted with the fixed sleeve 11.

[0101] In practical applications, the assembled fixing sleeve 11 and pressure head 13 are placed in the outer sleeve 15, which serves to fix the various mechanisms and facilitate the replacement of the components.

[0102] As shown in Figures 3 to 7, the fixed sleeve 11 includes a first half-cylinder 111, a second half-cylinder 112, and a longitudinal sealing member. The first half-cylinder 111 has a first half-groove inside; the second half-cylinder 112 has a second half-groove inside and is engaged with the first half-cylinder 111 through a positioning structure, so that the first half-groove and the second half-groove form a cavity for accommodating multiple solid spring clip material plates 12; the longitudinal sealing member is disposed 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.

[0103] This design facilitates the installation and replacement of the solid spring clip material plate 12, while also ensuring the overall structural strength. Furthermore, the specific heat capacity of the fixing sleeve 11 can be selected based on its material for heat preservation.

[0104] It should be noted that the fixing sleeve 11 is preferably made of a polymer material, specifically nylon, polyester, rigid silicone, resin, etc., and preferably polytetrafluoroethylene. During the stress loading process of the power mechanism 30, the solid spring clip material plate 12 will expand laterally. Using a polymer material can accommodate its expansion size, thus buffering the lateral pressure. On the other hand, the polymer material has low thermal conductivity, which can also prevent the heat of the heat-conducting fluid from being lost.

[0105] In one specific embodiment, the positioning structure between the first half-cylinder 111 and the second half-cylinder 112 can be a structure with a protrusion and a groove, or a hole or groove structure with positioning 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.

[0106] The cavity can be a cylindrical, cubic, or cuboid shape, with its inner wall in close contact with the solid spring clip material plate 12. During assembly, the solid spring clip material plate 12 can be placed into the fixing sleeve 11. The specific method of fixing the solid spring clip material plate 12 to the fixing sleeve 11 can be selected as needed.

[0107] Specifically, as shown in Figures 3, 4, 8, 11, and 12, in one embodiment, the pressure head 13 includes a dynamic pressure head 131, a dynamic pressure head seal, a hydraulic distribution head 132, and a driving pressure head 133. The dynamic pressure head 131 is slidably disposed within the cylinder cavity and abuts against the solid spring-loaded material plate 12. The dynamic pressure head 131 has a first flow-through hole communicating with the flow cavity. The dynamic pressure head seal is disposed between the dynamic pressure head 131 and the inner wall of the cylinder cavity to provide a seal and prevent medium leakage. The hydraulic distribution head 132 is connected to the end of the dynamic pressure head 131 facing away from the solid spring-loaded material plate 12 and has a second flow-through hole and several liquid distribution holes. The second flow-through hole communicates with the first flow-through hole, and each of the several liquid distribution holes has one end communicating with the second flow-through hole and the other end connected and communicating with the medium conveying pipeline assembly for the input and output of the heat-conducting medium. The driving pressure head 133 is slidably disposed within the outer sleeve 15 and is connected to the hydraulic distribution head 132 and the driving rod 25 to transmit power.

[0108] Preferably, the end of the dynamic pressure head 131 that contacts the solid spring-loaded material plate 12 has the same cross-sectional shape, and the first flow-through hole is located at the center of the dynamic pressure head 131 and coaxial with the cavity. In this embodiment, the end of the dynamic pressure head 131 that applies stress has the same cross-sectional shape and completely covers the cross-section of the solid spring-loaded material plate 12, which can ensure that the solid spring-loaded material plate 12 undergoes a complete phase change when stress is applied, thereby improving the efficiency of cooling and heating. In addition, setting the first flow-through hole at the center of the dynamic pressure head 131 can ensure that the heat-conducting fluid in the cavity is uniform at all angles and flows out of the first flow-through hole at the same velocity.

[0109] In order to increase the strength of the load, the dynamic pressure head 131 can be made of high-strength tungsten steel.

[0110] Furthermore, in order to reduce friction and improve the motion accuracy of the dynamic pressure head 131, a slide rail is provided inside the outer tube 15. The drive pressure head 133 slides along the slide rail in cooperation with the outer tube 15, so that the drive pressure head 133 slides along the slide rail when loading or unloading.

[0111] In some embodiments, the slide rail in the inner wall of the outer sleeve 15 that contacts the fixed sleeve 11 may be provided with a snap-fit ​​component for fixing the fixed sleeve 11. Alternatively, the slide rail may not be provided in the part of the inner wall of the outer sleeve 15 that overlaps with the fixed sleeve 11, and the slide rail may only be provided at the port of the outer sleeve 15.

[0112] In other embodiments, in order to achieve heat exchange, the heat-conducting fluid that absorbs heat or cold is transported to the heat exchange device as soon as possible. The plug structure 14 provided at the other end of the fixed sleeve 11 is a water-dividing plug. The water-dividing plug is provided with a liquid passage hole, which is connected to the flow cavity and connected to the medium conveying pipeline assembly for the input and output of the heat-conducting medium.

[0113] In some specific embodiments, as shown in Figures 1 and 2, the cooling and heating device further includes a housing 40, which covers the solid spring-loaded regenerator 10 and the multi-linkage transmission mechanism 20. A power mechanism 30 is mounted on the housing 40, with one end of the rotating main shaft 21 extending out of the housing 40. The multi-linkage transmission mechanism 20 also includes a compensating transmission component 27, which is located between the power mechanism 30 and the rotating main shaft 21 for compensating transmission. The main shaft support 26 can be fixed to the housing 40.

[0114] The compensation transmission component 27 can be a transmission component capable of distance compensation, such as a gear transmission component or a chain transmission component.

[0115] Specifically, the power mechanism 30 can be a power component that can output rotational power, such as a geared motor or an internal combustion engine.

[0116] As shown in Figures 13 to 16, this application provides a further specific implementation method based on the first implementation method as follows:

[0117] In this embodiment, the multi-linkage transmission mechanism 20 includes a mounting bracket, an eccentric wheel rod 28, and multiple drive rods 25. The mounting bracket is fixedly disposed relative to the solid-state spring-loaded regenerator 10. The eccentric wheel rod 28 is rotatably disposed on the mounting bracket and connected to the power mechanism 30. Multiple eccentric wheels 281 are spaced apart on the eccentric wheel rod 28, and the multiple eccentric wheels 281 are arranged with a non-zero phase angle. Multiple drive rods 25 are slidably disposed on the mounting bracket and are respectively disposed corresponding to multiple eccentric wheels 281. Each drive rod 25 has one end abutting against the corresponding eccentric wheel 281, and the other end connected to one of the solid-state spring-loaded regenerators 10, so as to input power to the solid-state spring-loaded regenerator 10 under the drive of the eccentric wheel 281. The part of the eccentric wheel rod 281 connected to the power mechanism 30 is the power input end, and the part of the drive rod 25 connected to the solid-state spring-loaded regenerator 10 is the power output end.

[0118] Specifically, the power mechanism 30 can be an electric motor, a hydraulic power component, a pneumatic power component, etc.

[0119] Compared with the prior art, the cooling and heating device provided in this embodiment can use a single power mechanism 30 to drive multiple solid-state spring-loaded regenerators 10 suitable for spring-loaded materials to perform cooling or heating through a multi-linkage transmission mechanism 20. After the multiple solid-state spring-loaded regenerators 10 are combined, a sufficient amount of heating or cooling capacity can be obtained to meet the needs of practical applications. Moreover, since the multiple eccentric wheels 281 on the eccentric wheel rod 28 are arranged with non-zero phase angles, the multiple solid-state spring-loaded regenerators 10 will be in different loading processes. After the loading is completed, the rebound force of the solid-state spring-loaded regenerator 10 will be transmitted back to the corresponding eccentric wheel 281 through the corresponding drive rod 25, and then transmitted to other eccentric wheels 281 through the eccentric wheel rod 28 for loading the corresponding solid-state spring-loaded regenerator 10. In this way, the rebound work of the solid-state spring-loaded regenerator 10 can be used to load other solid-state spring-loaded regenerators 10, which is beneficial to work recovery. This helps the power mechanism 30 to output power more stably and reduce energy loss.

[0120] As shown in Figure 16, the eccentric wheel 281 is a cylindrical structure integrally formed on the eccentric wheel rod 28. Reinforcing bodies 282 are provided at both ends of the eccentric wheel 281 to prevent breakage due to stress concentration at the ends. In one specific embodiment, the reinforcing body 282 is a crescent-shaped structure integrally formed on the eccentric wheel rod 28. The eccentricity of the eccentric wheel 281 should be consistent with the length compressed by the pressure head in the corresponding solid spring-loaded regenerator 10.

[0121] To ensure the stability of the eccentric wheel rod 28 while reducing frictional loss, a second bearing 29 forms a rotational fit between the mounting bracket and the eccentric wheel rod 28. A second bearing 29 is provided between each two adjacent eccentric wheels 281 to increase the force on the eccentric wheel rod 28. The second bearing 29 can be a bearing component such as a ball bearing, roller bearing, or air bearing, or other components that can function as a bearing.

[0122] The adjacent eccentric wheels 281 on the eccentric wheel rod 28 have a phase angle of 360 / n, where n is the number of eccentric wheels 281. This ensures that the torque is approximately the same when the eccentric wheel rod 28 rotates, allowing different solid-state spring-loaded regenerators 10 to operate in turn. This guarantees the stability of the structure and power output, reduces the swaying of the eccentric wheel rod 28, minimizes mechanical wear and noise, reduces frictional losses, and improves energy utilization.

[0123] The end of the drive rod 25 facing the eccentric wheel 281 is provided with a wear-resistant block 254 to reduce wear.

[0124] In this embodiment, the multi-linkage transmission mechanism 20 has a different composition structure from the multi-linkage transmission mechanism 20 in the previous embodiment. However, the mounting bracket in this embodiment can refer to or adopt the spindle bracket 26 shown in Figure 2 of the previous embodiment. The eccentric wheel rod 28 in this embodiment can refer to or adopt the rotating spindle 21 shown in Figure 3 of the previous embodiment. The drive rod 25 in this embodiment can refer to or adopt the drive rod 25 shown in Figure 3 of the previous embodiment.

[0125] It is understood that when the multi-linkage transmission mechanism 20 in this embodiment is applied to a refrigeration and heating device, it can also adopt the same structure as the heat transfer medium collection mechanism, solid spring-loaded regenerator 10 in the aforementioned embodiments (e.g., fixed sleeve 11, solid spring-loaded material plate 12, pressure head 13, plug structure 14, and medium conveying pipeline assembly), the cooperation structure between the drive rod 25 and the pressure head 13, the outer shell 40, and the compensation transmission assembly 27, etc., which will not be described in detail here. Among them, when the outer shell 40 is used, one end of the eccentric wheel rod 28 protrudes from the outer shell 40, and the compensation transmission assembly 27 is disposed between the power mechanism 30 and the eccentric wheel rod 28.

[0126] Furthermore, based on the above two embodiments of the multi-linkage transmission mechanism 20, in some embodiments, as shown in Figures 1, 13, and 14, the outer shell 40 includes a first outer shell 41, a limiting end plate 42, and a bottom sealing plate 43. The first outer shell 41 has multiple cavities inside, which are used to accommodate the solid spring-loaded regenerator 10. The limiting end plate 42 is located at the end of the first outer shell 41 facing the multi-linkage transmission mechanism 20, and is used to limit the solid spring-loaded regenerator 10. The limiting end plate 42 has a through hole at the part corresponding to the cavity for the power output end of the multi-linkage transmission mechanism 20 to pass through. The bottom sealing plate 43 is located at the end of the first outer shell 41 away from the multi-linkage transmission mechanism 20, and is detachably connected to the first outer shell 41 and connected to the end of the solid spring-loaded regenerator 10.

[0127] During assembly, the multi-linkage transmission mechanism 20 can be connected to one end of the first outer shell 41, and the solid spring-loaded regenerator 10 can be installed into the corresponding cavity from the other end of the first outer shell 41. It can be 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 simple and convenient, and the multi-linkage transmission mechanism 20 can stably load and unload the solid spring-loaded regenerator 10, ensuring the stability of equipment operation.

[0128] As shown in Figure 1, the outer casing 40 also includes a second outer casing 45, which is connected to the first outer casing 41. A multi-linkage transmission mechanism 20 is located inside the second outer casing 45, and a power mechanism 30 is located on the outer casing 40, with one end of the rotating main shaft 21 or eccentric wheel 28 extending out of the outer casing 40. Specifically, the power mechanism 30 can be located outside the second outer casing 45, with the rotating main shaft 21 or eccentric wheel 28 extending out from within the second outer casing 45.

[0129] In some embodiments, the dynamic pressure head 131 can be a T-shaped cross-section structure; the first flow-through orifice includes multiple micro-holes, and the second flow-through orifice includes a micro-hole section and a converging section, with the micro-hole section communicating with the micro-holes to facilitate the flow of the heat transfer medium; the plug structure 14 is provided with a third flow-through orifice, and the bottom sealing plate 43 is provided with a fourth flow-through orifice. The third flow-through orifice also includes a micro-hole section and a converging section, with the micro-hole section communicating with the flow cavity and the converging section communicating with the fourth flow-through orifice. This facilitates the discharge of the heat transfer medium from both ends of the solid spring-loaded regenerator 10, thereby improving the circulation efficiency of the heat transfer medium.

[0130] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
