Description

Technical Field

[0001] This utility model belongs to the field of refrigeration and heating technology, and particularly relates to a regenerative device and a refrigeration and heating device. Background Technology

[0002] Solid-state spring-loaded cooling and heating is an emerging green and environmentally friendly cooling and heating technology. It uses solid-state spring-loaded materials to cause phase change or reverse phase change to generate heat or cold, thereby achieving cooling or heating.

[0003] The refrigeration and heating device based on this principle applies stress to a solid elastic material through a driving device and sets a flow cavity in the solid elastic material. A heat-conducting fluid is passed through the material under the action of a pump, and the heat or cold generated is transferred using the heat-conducting fluid. When loading the solid elastic material, excessive loading and unloading cycles can cause local buckling deformation of the blocky solid elastic material. Therefore, the solid elastic material is designed as sheets, each with perforations. After stacking, the perforations form a flow cavity. However, in practical applications, during the stress application process of the driving device, the stacked sheets are easily misaligned, causing blockage of the flow cavity and reducing the thermal conductivity of the heat-conducting fluid.

[0004] To improve heat transfer efficiency, the flow rate of the heat transfer fluid should be increased as much as possible. A common approach is to reduce the cross-sectional area of ​​the flow cavity while maintaining a given pump power. This is achieved by designing a smaller shape or adding a stopper to a larger shape. However, considering the flow resistance, an excessively small flow cavity will significantly limit the flow rate of the heat transfer fluid, hindering heat transfer. Adding a stopper will cause the actuator to simultaneously apply stress to the stopper, and the reaction force of the stopper will result in excessively low actuator loading efficiency, increasing the energy consumption ratio of the refrigeration and heating device. Utility Model Content

[0005] This application provides a heat recovery device, including: a sleeve and solid spring clip material plates. The inner wall of the sleeve includes protrusions and multiple solid spring clip material plates are stacked inside the sleeve. Each solid spring clip material plate includes a groove. The space formed by stacking the multiple grooves is used to accommodate the protrusions of the inner wall of the sleeve. After the protrusions extend into the space formed by the stacked grooves, the gap between the inner wall of the sleeve and the outer surface of the stacked solid spring clip material plates forms a flow cavity for the flow of heat-conducting fluid.

[0006] Furthermore, each of the solid spring clip material plates has multiple grooves that correspond one-to-one with the protrusions on the inner wall of the sleeve, and the edges of the grooves are serrated.

[0007] Furthermore, the gap between the inner wall of the sleeve and the edge of the groove of the solid spring clip material plate is 0.1-5mm, preferably 0.1-2.0mm.

[0008] Furthermore, the surface of the solid spring card material plate also includes: perforations, which are stacked to form a second flow cavity.

[0009] Furthermore, the outer surface of the protrusion engages with the inner surface of the stacked groove, and a partition is provided on the inner wall of the sleeve, the partition being Teflon, POM, nylon, polyester, or silicone.

[0010] Furthermore, the convex surface of the protrusion engages with the concave surface of the groove, such that the remaining inner wall of the sleeve (excluding the convex surface) and the outer edge of the remaining solid elastic material plate (excluding the concave surface) form a flow cavity.

[0011] Furthermore, the thickness of the solid spring clip material plate is 0.01-100mm, preferably 0.1-10mm.

[0012] A refrigeration and heating device includes: a regenerative device and a driver as described above;

[0013] The actuator includes a power element, a pressure rod, and a pressure head. The power element is connected to one end of the pressure rod, and the pressure head is located at the other end of the pressure rod. The power element drives the pressure rod to cause the pressure head to reciprocate within the sleeve to load or unload the solid spring plate material.

[0014] Furthermore, the shape of the pressure head is the same as the shape of the solid spring card material plate.

[0015] Furthermore, the pressure head is made of ceramic or tungsten steel.

[0016] In this embodiment of the invention, a protrusion is provided on the inner wall of the sleeve and extends into the groove of the solid spring-loaded material plate. This serves two purposes: firstly, it fixes the position of the solid spring-loaded material plate, preventing it from moving and becoming misaligned; secondly, the flow cavity formed by the gap between the groove space created by the stacked solid spring-loaded material plates and the protrusion is elongated and slender, resulting in a larger size and lower flow resistance. Furthermore, the protrusion's obstruction increases the flow velocity of the heat-conducting fluid, thus increasing the heat transfer efficiency. In addition, the larger contact area between the flow cavity and the solid spring-loaded material further enhances the heat transfer efficiency. Moreover, designing the actuator's pressure head to be the same shape as the solid spring-loaded material plate avoids the reaction force when the actuator loads the solid spring-loaded material plate, improving the energy efficiency ratio of the cooling and heating device.

[0021] 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.

[0022] like Figure 1 The present invention provides a heat recovery device, comprising: a sleeve 1 and a solid spring clip material plate 2. The inner wall of the sleeve 1 includes a protrusion 11 and multiple solid spring clip material plates 2 are stacked inside the sleeve 1. Each solid spring clip material plate 2 includes a groove 21. The space formed by the stacking of multiple grooves 21 is used to accommodate the protrusion 11 of the inner wall of the sleeve. After the protrusion 11 extends into the space formed by the stacked grooves 21, the gap between the inner wall of the sleeve 1 and the outer surface of the stacked solid spring clip material plates 2 forms a flow cavity for the flow of heat-conducting fluid.

[0023] In practical applications, the larger the volume (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.

[0024] In one embodiment of this utility model, each solid spring-loaded card material plate has multiple grooves 21 corresponding to multiple protrusions 11 on the inner wall of the sleeve 1. The number of protrusions 11 on the inner wall of the sleeve 1 is the same as the number of grooves 21 formed after the solid spring-loaded card material plates 2 are stacked, and the protrusions 11 are respectively embedded in the grooves 21 of the solid spring-loaded card material plates 2. In this embodiment, the protrusions 12 extend longitudinally along the sleeve, and their length is greater than or equal to the length of the solid spring-loaded card material plates 2 after stacking. In this way, the position of the solid spring-loaded card material plates 2 can be fixed to a certain extent, limiting their misalignment. In order to increase the cross-sectional area of ​​the flow cavity, multiple protrusions 11 and grooves 21 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 21 of the solid spring-loaded card material plate 2 to form a small microfluidic cavity and increase the contact area between the heat-conducting fluid and the solid spring-loaded card material, thereby increasing the heat conduction efficiency.

[0025] It should be noted that 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, resulting in higher heat transfer efficiency.

[0026] It should be noted that the gap between the inner wall of the sleeve 1 and the edge of the groove 21 of the solid spring material plate 2 is 0.1-5mm, preferably 0.5-1mm. Under this size, the flow resistance can be minimized and the flow rate can be maximized.

[0027] It should be noted that the solid spring-loaded material plate will expand laterally during loading. Therefore, to ensure sufficient space for expansion, a partition is provided on the inner wall of the sleeve and the raised surface. For example, a partition film can be coated or adhered to the inner wall of the sleeve. This partition film can be made of Teflon, POM, nylon, polyester, or silicone. On the one hand, the soft film can accommodate and buffer the expansion of the solid spring-loaded material plate; on the other hand, the film has a heat insulation function, minimizing heat loss when the medium exchanges heat through the flow cavity. In practical applications, Teflon and POM are preferred. For ease of assembly, a brush coating method is used. After applying the Teflon coating to the inner wall of the sleeve, the solid spring-loaded material plate is placed into the cavity of the sleeve, making the operation convenient.

[0028] Furthermore, the solid spring-loaded card material plate 2 also includes perforations, which are stacked to form a second flow cavity. In this embodiment of the invention, multiple perforations are provided on the solid spring-loaded card material plate, and the perforations are aligned to form a flow cavity after the solid spring-loaded card material plates are stacked. In an embodiment where the solid spring-loaded card material plate is connected to the inner wall of the sleeve, the edge of the solid spring-loaded card material plate and the inner wall of the sleeve 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.

[0029] 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.

[0030] In practical applications, if there are gaps between the inner wall of the sleeve and the solid spring clip material plate, slight misalignment of the solid spring clip material plate may occur, making it difficult to align the perforations on its surface and affecting the flow rate of the heat-conducting fluid in the second flow cavity. To solve this problem, the utility model provides an embodiment in which the outer surface of the protrusion contacts the inner surface of the stacked groove, that is, only the protrusion and the groove are locked together without gaps, so that a gap remains between the inner wall of the sleeve and the outer edge of the solid spring clip material plate, thereby limiting the misalignment of the solid spring clip material plate.

[0031] In a preferred embodiment, the convex surface of the protrusion on the inner wall of the sleeve engages with the concave surface of the groove, thereby forming a flow cavity between the inner wall of the sleeve and the outer edge of the solid elastic clamping material plate, and also forming a flow cavity between the side surface of the protrusion and the side surface of the groove. This further increases the cross-sectional area of ​​the flow cavity, thereby increasing heat conduction.

[0032] like Figures 2-3 This utility model embodiment also provides a cooling and heating device, including: the above-mentioned regenerator 10 and driver 20;

[0033] The driver 20 includes a power element 201, a pressure rod 202, and a pressure head 203. The power element 201 is connected to one end of the pressure rod 202, and the pressure head 203 is located at the other end of the pressure rod 202. The power element 201 drives the pressure rod 202 to make the pressure head 203 reciprocate within the sleeve to load or unload the solid spring card material plate.

[0034] Specifically, the power component 201 can be: a motor, a hydraulic power component, a pneumatic power component, etc.

[0035] It should be noted that the shape of the pressure head 203 is the same as the cross-sectional shape of the solid spring plate. In this way, when the pressure head applies stress to the solid spring plate, it can avoid applying force to the protrusion at the same time, thus increasing the energy efficiency of the cooling and heating device.

[0036] To increase the loading strength, the pressure head can be made of high-strength ceramic or 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. In this embodiment, the pipeline, not shown in the figure, acts as a container for the medium flow 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.

[0037] 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.
