[0002] Solid-state spring card cooling and heating is an emerging green and environmentally friendly cooling and heating technology. By loading or unloading solid-state spring card materials, it causes phase change or reverse phase change to generate heat or cold, thereby achieving cooling or heating.

[0003] In the cooling and heating device prepared based on this principle, when the driver therein is loaded with solid-state spring-loaded materials, the excessive number of loading and unloading times will cause cracks in the block-shaped solid-state spring-loaded materials, which will cause the entire block of material to fail, reduce its service life, and easily cause the material to buckle and deform. Therefore, in order to solve this problem, the solid-state spring-loaded materials are prepared in a plate shape. However, in actual applications, due to the large number of plate-shaped solid-state spring-loaded materials, not only is the assembly complicated, but it is also more prone to misalignment, affecting the loading of the driver. In addition, when a fault occurs during operation, it is inconvenient to inspect. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

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

[0019] The present invention provides a heat recovery device, comprising: a sleeve 1, a plurality of solid spring-cage material plates 2 stacked and placed in the sleeve 1, and a pressure head 3 for applying stress to the solid spring-cage material plates 2. The sleeve 1 is composed of a plurality of components and is used for inspecting or loading and unloading the plurality of solid spring-cage material plates 2 when unfolded; each solid spring-cage material plate 2 has a flow cavity after being stacked, and a heat-conducting medium exchanges heat with the solid spring-cage material plate 2 through the flow cavity when generating heat or cold, and flows into a heat exchanger through a liquid hole 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 detachable, so that when assembling the solid spring card material plate 2, it can be ensured that each solid spring card material plate 2 is aligned and the through holes thereon are aligned, so that each solid spring card material plate 2 is evenly stressed during loading, and blockage is avoided when the heat conductive medium flows, thereby improving the heat conduction efficiency.

[0021] In one embodiment, in order to facilitate assembly, the sleeve 1 can be set as two parts, that is, the sleeve 1 includes: a base 11 and a cover 12. After the base 11 and the cover 12 are fastened, a cavity is formed inside, and a plurality of solid spring card material plates 2 are placed in the cavity. Among them, the size of the base 11 and the cover 12 is not limited. In practical applications, since the force applied to the solid spring card material plate 2 is relatively large, 1000-100000N, in order to ensure that it withstands a large force, the sleeve is usually made of stainless steel material with a thickness (the thickness from the inner wall of the cavity to the outer wall of the sleeve) of 1-30cm. When fastened, it can be fastened by pins, screws, etc. At the same time, in order to prevent the thermal conductive medium therein from leaking, a sealing ring is set at the connection between the base 11 and the cover 12. Specifically, the sealing ring is Teflon, POM, nylon, polyester or silicone.

[0022] In the embodiment of the present invention, the solid-state spring card material is set to a plate shape. Since each piece is independently stressed, during the loading and unloading process, even if cracks appear in some solid-state spring card materials, only the solid-state spring card material plate where it is located will fail, and the cracks will not spread to other solid-state spring card material plates, that is, it will not cause the overall failure of the solid-state spring card material to affect the overall work, thereby improving the service life of the solid-state spring card material. In addition, after the plate-shaped solid-state spring card material is piled up, the damage to the material of the present application caused by the loading force will be greatly reduced during the loading process, avoiding the buckling deformation of the material.

[0023] In one embodiment, in order to further avoid the dislocation of the solid spring-cage material plate, a protrusion is provided on the base 11 or / and the cover 12 along the axial direction, and a groove is provided on the edge of the solid spring-cage material plate 2. During assembly, the protrusion is inserted into the groove at the edge of the solid spring-cage material plate 2. The shapes of the protrusion and the groove are not limited. In order to expand the cross-section of the flow cavity, the convex surface of the protrusion and the concave surface of the groove can be stuck, that is, 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 except the protrusion and the edge of the solid spring-cage material plate except the groove. In this way, the cross-sectional area of ​​the flow cavity can be expanded, thereby increasing the thermal conductivity efficiency of the heat-conducting medium.

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

[0025] In this embodiment, the pressure head 3 includes: a liquid through hole, a liquid inlet 322 and a liquid outlet 323, and the liquid inlet 322 and the liquid outlet 323 are connected to the perforation through the liquid through hole. In a preferred embodiment, the pressure head 3 also includes: a first pressure head 31 extending into the cavity and a second pressure head 32 connected to the first pressure head 31, wherein the first pressure head 31 has a plurality of through holes and is connected to the through holes on the solid spring card material plate 2 to form a first liquid through hole 311. The liquid inlet 322 and the liquid outlet 323 are placed on the second pressure head 32 and are connected to the second liquid through hole 321 provided on the second pressure head 32. The second liquid through hole 321 is trumpet-shaped and is used to gather the outflowing heat-conducting medium. The first pressure head 31 is ceramic, tungsten steel or stainless steel.

[0026] It should be noted that the trumpet-shaped second liquid hole 321 and the pipe section connected to the liquid inlet 322 and the liquid outlet 323 are larger than the first liquid hole 311 in the first pressure head 31, so that the heat transfer medium can be quickly gathered and the heat transfer speed of the heat transfer medium can be increased.

[0027] In another embodiment, the heat recovery device also 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 connected to the solid spring material plate 2, and the second plug 42 includes a liquid hole 43, a plug liquid inlet 44 connected to the liquid hole 43, and a plug liquid outlet 45, wherein the liquid hole at the connection between the second plug 42 and the first plug 41 is a trumpet-shaped cavity.

[0028] In this embodiment, in order to fully load the solid spring-stuck material plate, the cross-sectional shape of the first pressing head and the first plugging head is the same as the cross-sectional shape of the solid spring-stuck material plate.

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

[0030] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
