Description

Technical Field

[0001] This invention belongs to the field of refrigeration and heating technology, and particularly relates to a regenerative device for an easily assembled solid spring-loaded cartridge. Background Technology

[0002] Solid-state cartridge cooling and heating is an emerging green and environmentally friendly cooling and heating technology. It involves loading or unloading solid-state cartridge materials to induce a phase change or reverse phase change, thereby generating heat or cold for cooling or heating.

[0003] In refrigeration and heating devices based on this principle, excessive loading and unloading cycles can cause cracks in the solid spring-loaded material, leading to the failure of the entire material, reduced lifespan, and increased susceptibility to buckling deformation. Therefore, to address this issue, the solid spring-loaded material is fabricated as a plate. However, in practical applications, the large number of plate-shaped solid spring-loaded materials not only complicates assembly but also increases the likelihood of alignment errors, affecting the driver's loading. Furthermore, it makes inspection difficult when malfunctions occur during operation. Summary of the Invention

[0004] This application provides a reheating device for an easily assembled solid spring clip, comprising: a sleeve, a plurality of solid spring clip material plates stacked inside the sleeve, and a pressure head that applies stress to the solid spring clip material plates. The sleeve is composed of multiple components and is used to inspect or load / unload the plurality of solid spring clip material plates when unfolded. Each of the solid spring card material plates, after being stacked, has a flow cavity. The heat-conducting medium exchanges heat with the solid spring card material plate through the flow cavity when heat or cold is generated, and flows into the heat exchanger through the liquid passage in the pressure head for heat exchange.

[0005] Furthermore, the sleeve includes a base and a cover, which, when fastened together, form an interior cavity in which the plurality of solid spring clip material plates are placed.

[0006] Furthermore, the edge of the solid spring-loaded material plate is provided with a groove; The base and / or the cover are provided with a protrusion along the axial direction, and the protrusion is engaged in the groove at the edge of the solid spring clip material plate.

[0007] Furthermore, the sleeve also includes a sealing ring, which is disposed at the connection between the base and the cover.

[0008] Furthermore, the solid spring card material plate includes perforations, which are stacked to form the flow cavity; The pressure head includes an inlet and an outlet, which are connected to the perforation through the liquid passage.

[0009] Furthermore, the pressure head also includes: a first pressure head extending into the cavity and a second pressure head connected to the first pressure head, wherein the first pressure head has a plurality of through holes and communicates with the through holes on the solid spring plate to form a first liquid passage hole.

[0010] Furthermore, the liquid inlet and the liquid outlet are disposed on the second pressure head and communicate with the second liquid passage hole disposed on the second pressure head. The second liquid passage hole is funnel-shaped and is used to collect the outflowing heat-conducting medium.

[0011] Furthermore, the sealing ring is made of Teflon, POM, nylon, polyester, or silicone; the perforation is polygonal, radial, spiral, circular, or square; and the thickness of the solid spring clip material plate is 0.01-100 mm, preferably 0.1-10 mm.

[0012] Furthermore, the first pressure head is made of ceramic, tungsten carbide, or stainless steel.

[0013] The present invention also provides a cooling and heating device, comprising: a regeneration device, a driving device, and a heat exchange device as described above; The driving device includes a power element and a piston mechanism. The power element drives the piston mechanism to compress the pressure head, causing the solid spring plate to undergo a phase change and generate heat when loading and unloading the compression, and causing the solid spring plate to undergo a reverse phase change and generate cold. The heat exchange device is connected to the regenerator through a pipeline, allowing the heat-conducting medium that absorbs heat or cold to exchange heat.

[0014] This invention designs the sleeve as multiple detachable or foldable components, which allows multiple solid spring clip material plates to be conveniently placed during assembly. This not only facilitates alignment but also makes it easy to open and inspect even if a problem occurs with a solid spring clip material plate during loading and unloading. Thus, it not only improves assembly efficiency but also improves troubleshooting efficiency. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] like Figures 1-5 As shown, the present invention provides a regenerative device comprising: a sleeve 1, a base 11, a cover 12, a solid spring clip material plate 2, a pressure head 3, a first pressure head 31, a first liquid passage hole 311, a second pressure head 32, a second liquid passage hole 321, a liquid inlet 322 and a liquid outlet 323, a plug 4, a first plug 41, a second plug 42, a liquid passage hole 43, a plug inlet 44 and a plug outlet 45.

[0019] This invention provides a regenerative device, comprising: a sleeve 1, a plurality of solid spring clip material plates 2 stacked inside the sleeve 1, and a pressure head 3 for applying stress to the solid spring clip material plates 2. The sleeve 1 is composed of multiple components and is used to inspect or load / unload the plurality of solid spring clip material plates 2 when unfolded. Each solid spring clip material plate 2 has a flow cavity after being stacked. The heat transfer medium exchanges heat with the solid spring clip material plate 2 through the flow cavity when heat or cold is generated, and flows into the heat exchanger through the liquid passage in the pressure head for heat exchange.

[0020] Among them, multiple parts of the sleeve 1 can be folded and unfolded or multiple parts can be disassembled. In this way, when assembling the solid spring clip material plate 2, it can be ensured that each solid spring clip material plate 2 is aligned and the through holes on it are aligned. This ensures that each solid spring clip material plate 2 is subjected to force evenly during loading and avoids blockage when the heat transfer medium flows, thereby improving the heat transfer efficiency.

[0021] In one embodiment, for ease of assembly, the sleeve 1 can be configured as two parts: a base 11 and a cover 12. When the base 11 and cover 12 are fastened together, an internal cavity is formed, in which multiple solid spring-loaded material plates 2 are placed. The size of the base 11 and cover 12 is not limited. In practical applications, since the force applied to the solid spring-loaded material plates 2 is relatively large (1000-100000N), to ensure it can withstand this large force, the sleeve is typically made of stainless steel with a thickness (from the inner wall of the cavity to the outer wall of the sleeve) of 1-30cm. It can be secured using pins, screws, etc. Simultaneously, to prevent leakage of the heat-conducting medium, a sealing ring is provided at the connection between the base 11 and cover 12. Specifically, the sealing ring is made of Teflon, POM, nylon, polyester, or silicone.

[0022] In this embodiment of the invention, the solid spring clip material is configured as a plate. Since each plate is independently stressed, even if cracks appear in some solid spring clip materials during loading and unloading, only the plate containing the crack will fail; the cracks will not spread to other plates. That is, the entire solid spring clip material will not fail, affecting overall operation, thus improving the service life of the solid spring clip material. Furthermore, the stacked plate-shaped solid spring clip material significantly reduces the damaging effect of loading forces on the material during loading, preventing buckling deformation.

[0023] In one embodiment, to further prevent misalignment of the solid spring clip material plate, a protrusion is provided along the axial direction on the base 11 and / or the cover 12, and a groove is provided on the edge of the solid spring clip material plate 2. During assembly, the protrusion is engaged into the groove on the edge of the solid spring clip material plate 2. The shapes of the protrusion and groove are not limited; to expand the cross-sectional area of ​​the flow cavity, the convex surface of the protrusion and the concave surface of the groove can be engaged, i.e., a gap is formed between the sides of the protrusion and the groove, and a gap is formed between the inner wall of the sleeve (excluding the protrusion) and the edge of the solid spring clip material plate (excluding the groove). This expands the cross-sectional area of ​​the flow cavity, thereby increasing the thermal conductivity of the heat-conducting medium.

[0024] In one embodiment, perforations can be formed on the surface of the solid spring-loaded card material plate. These perforations can form a flow cavity after being stacked. Alternatively, grooves (e.g., serrated) can be formed on the edge of the solid spring-loaded card material plate. After stacking, the grooves form a gap with the inside of the sleeve, thereby obtaining a flow cavity for the flow of heat-conducting medium. The shape of the perforations is not limited and can be polygonal, radial, spiral, circular, or square. The thickness of the solid spring-loaded card material plate is 0.01-100 mm, preferably 0.1-10 mm.

[0025] In this embodiment, the pressure head 3 includes a liquid passage hole, a liquid inlet 322, and a liquid outlet 323. The liquid inlet 322 and the liquid outlet 323 are connected to a perforation through the liquid passage hole. In a preferred embodiment, the pressure head 3 further includes a first pressure head 31 extending into the cavity and a second pressure head 32 connected to the first pressure head 31. The first pressure head 31 has multiple through holes and communicates with through holes on the solid spring plate 2 to form a first liquid passage hole 311. The liquid inlet 322 and the liquid outlet 323 are located on the second pressure head 32 and communicate with the second liquid passage hole 321 located on the second pressure head 32. The second liquid passage hole 321 is funnel-shaped and is used to collect the outflowing heat-conducting medium. The first pressure head 31 is made of ceramic, tungsten carbide, or stainless steel.

[0026] It should be noted that the cross-section of the funnel-shaped second liquid passage 321 and the pipe connected to the liquid inlet 322 and the liquid outlet 323 is larger than that of the first liquid passage 311 in the first pressure head 31. In this way, the heat-conducting medium can be quickly gathered, increasing the heat conduction speed of the heat-conducting medium.

[0027] In another embodiment, the regenerating device further includes a plug 4, wherein the plug 4 includes a first plug 41 and a second plug 42, wherein the first plug 41 extends into the cavity and has a flow cavity communicating with the solid elastic material plate 2, and the second plug 42 includes a liquid passage hole 43, a plug inlet 44 communicating with the liquid passage hole 43 and a plug outlet 45, wherein the liquid passage hole at the connection between the second plug 42 and the first plug 41 is a funnel-shaped cavity.

[0028] In this embodiment, in order to fully load the solid spring plate, the cross-sectional shapes of the first pressure head and the first plug are the same as the cross-sectional shape of the solid spring plate.

[0029] It should be noted that during the heating process of the regenerative device, the solid spring-loaded material plate is loaded, and the heat transfer medium enters the flow cavity of the solid spring-loaded material plate through the liquid inlet of the pressure head or plug to absorb heat. After loading is completed, it flows out through the liquid outlet of the plug or pressure head to the heat exchanger for heat exchange. Alternatively, during the cooling process of the regenerative device, the solid spring-loaded material plate is unloaded, and the heat transfer medium enters the flow cavity of the solid spring-loaded material plate through the liquid inlet of the pressure head or plug to absorb cold energy. After unloading is completed, it flows out through the liquid outlet of the plug or pressure head to the heat exchanger for heat exchange.

[0030] The above content is only a preferred embodiment of this application and is 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.
