In practical applications, solid spring-loaded material is typically designed by combining multiple solid spring-loaded material units. During the stress application process by the driving device, these units can easily become misaligned, causing blockage of the flow cavity and reducing the thermal conductivity of the heat-conducting fluid. Furthermore, misalignment can prevent the driving device from fully applying stress to the surface of the solid spring-loaded material plate during loading, preventing some units from undergoing phase change and resulting in reduced heat and cold generation, thus lowering the overall cooling and heating efficiency.

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0023] like Figure 1 The present invention provides a regenerative device based on solid spring-loaded refrigeration and heating, comprising: a fixing mechanism 1, solid spring-loaded refrigeration and heating material 2 arranged sequentially in the fixing mechanism 1, a driving mechanism 3, and a sleeve 4, wherein the fixing mechanism 1 and the driving mechanism 3 are disposed within the sleeve 4.

[0024] The drive mechanism 3 includes a dynamic pressure head 31 with a through hole 311. The dynamic pressure head 31 extends into the fixed mechanism 1 to apply stress or unload stress to the solid spring cooling and heating material 2.

[0025] The perforations on the solid spring-loaded cooling and heating material 2 are arranged to form cavities, which are connected to the through holes 311 to allow the heat-conducting fluid to exchange the heat generated by the solid spring-loaded cooling and heating material 2 during flow.

[0026] In this embodiment, as Figure 2 As shown, the fixing mechanism 1 is used to fix the solid spring-loaded cooling and heating materials 2 arranged and stacked according to their cross-sections. The fixing method of the fixing mechanism 1 is not limited; it only needs to have sufficient space at one or both ends after fixing to allow the dynamic pressure head 31 to extend into it. Preferably, the fixing mechanism is a cylinder, cube, cuboid, etc., with an internal cavity, and its inner wall is in close contact with the solid spring-loaded cooling and heating materials 2. Thus, during assembly, the solid spring-loaded cooling and heating materials 2 can be placed into the fixing mechanism. It should be noted that the solid spring-loaded cooling and heating materials 2 can be in block, plate, or sheet form; their shape is not limited.

[0027] It should be noted that the fixing mechanism 1 is preferably made of a polymer material, specifically nylon, polyester, rigid silicone, resin, etc., and preferably polytetrafluoroethylene. During the stress loading process of the driving mechanism 3, the solid spring-loaded cooling and heating material 2 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 transfer fluid from being lost.

[0028] In this embodiment, the solid spring-loaded cooling and heating material 2 has perforations. During stacking, the perforations are aligned to form channels for the flow of heat-conducting fluid. For further assembly convenience, alignment components can be provided on the inner wall of the fixing mechanism, specifically notches, irregular shapes, or external limiting components. Simultaneously, each solid spring-loaded cooling and heating material 2 is marked with corresponding alignment marks according to the alignment components. A preferred embodiment is as follows... Figure 3 As shown, an irregular shape is preferred, but the specific shape is not limited. It should be noted that the shape of the perforations is not limited and can be one or more of square, circular, radial, or spiral shapes. Preferably, radial or spiral shapes are selected to improve heat exchange capacity.

[0029] Furthermore, the dynamic pressure head 31 in the drive mechanism 3 has the same cross-sectional shape at the end that contacts the solid spring-loaded cooling and heating material 2, and the through hole 311 is located at the center of the dynamic pressure head 31 and coaxial with the cavity. In this embodiment, the cross-sectional shape of the dynamic pressure head 31 and the end of the solid spring-loaded cooling and heating material 2 that applies stress is matched. For example, if they have the same shape and stress is applied, the cross-sections of the dynamic pressure head 31 and the solid spring-loaded cooling and heating material 2 overlap, or if they have different shapes, the cross-section of the dynamic pressure head 31 completely covers the cross-section of the solid spring-loaded cooling and heating material, which can ensure that the solid spring-loaded cooling and heating material undergoes a complete phase change when the drive mechanism 3 applies stress, thereby improving the efficiency of cooling and heating. In addition, setting the through hole 311 at the center of the dynamic pressure head 31 can ensure that the heat-conducting fluid in the cavity is uniform at all angles and flows out of the through hole 311 at the same velocity.

[0030] It should be noted that the thickness of the solid spring card material plate is 0.01-100mm, preferably 0.1-10mm, and more preferably 0.15-0.3mm.

[0031] In this embodiment, the sleeve 4 is used to fix the fixing mechanism 1 and the driving mechanism 3. That is, in practical applications, the assembled fixing mechanism 1 and driving mechanism 3 are placed in the sleeve 4, which serves to fix each mechanism and facilitate the replacement of the components.

[0032] In one embodiment, such as Figure 1As shown, the drive mechanism 3 includes: a dynamic pressure head 31, a first distribution pressure head 32, and a drive pressure head 33. One end of the dynamic pressure head 31 is fixed to the first distribution pressure head 32, which has a distribution pipe 321 connected to a through hole for discharging the heat-conducting fluid. The other end of the first distribution pressure head 32 is fixed to the drive pressure head 33, which is also fixed to a driver. The distribution pipe 321 includes: a main pipe, a first branch pipe, and a second branch pipe connected to the main pipe. The main pipe is connected to the through hole; the first branch pipe allows the heat-conducting fluid to flow out, and the second branch pipe allows the heat-conducting fluid to flow in.

[0033] To increase the strength of the load, the dynamic pressure head can be made of high-strength tungsten steel. To ensure the medium flows smoothly within the flow cavity, a sealing ring is installed at the connection between the pressure rod and the pressure head to form a closed flow cavity and prevent medium leakage.

[0034] In some embodiments, to reduce the friction between the first hydraulic head 32 and the driving head 33 in the drive mechanism and the sleeve 4, a slide rail 41 is provided inside the sleeve 4. The surfaces of the first hydraulic head 32 and the driving head 33 are provided with tracks that cooperate with the slide rail 41, for sliding along the slide rail 41 when the first hydraulic head 32 and the driving head 33 in the drive mechanism 3 are loaded or unloaded. In some embodiments, the slide rail in the inner wall of the sleeve 4 that contacts the fixing mechanism 1 may be provided with a snap-fit ​​member for fixing the fixing mechanism 1, or the slide rail may not be provided in the part of the inner wall of the sleeve 4 that overlaps with the fixing mechanism 1, and the slide rail may only be provided at the port of the sleeve 4.

[0035] In some 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. A water distribution plug is provided at the other end of the fixing mechanism 1. The water distribution plug is provided with a liquid passage hole. The liquid passage hole is coaxial with the cavity. For details on the function of the liquid passage hole, please refer to the function of the through hole in the dynamic pressure head 31.

[0036] Furthermore, the fixing mechanism 1 also includes: the second hydraulic head includes a main pipeline, a first liquid distribution pipeline, and a second liquid distribution pipeline, the main pipeline being connected to the liquid passage, the first liquid distribution pipeline, and the second liquid distribution pipeline, respectively. For details of their specific functions, please refer to the main pipeline, the first liquid distribution pipeline, and the second liquid distribution pipeline in the first hydraulic head.

[0037] This utility model embodiment also provides a cooling and heating device, including: the heat recovery device and the heat exchange device as described above;

[0038] The regenerator and the heat exchanger are connected by pipelines, which are used to transfer the heat-conducting fluid that has absorbed heat and heated up, or the heat-conducting fluid that has released heat and cooled down, to the heat exchanger for heat exchange. It should be noted that the pipelines can be inserted into the first and second distribution pipes of the first and second hydraulic heads, so that the heat-conducting fluid flows into the heat exchanger for heat exchange.

[0039] In this embodiment, the pipeline is not shown in the figure. It serves as a container for the flow of the medium and is connected to the heat exchange device of the equipment, allowing the medium to flow into the heat exchange device and release heat or cold.
