Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and particularly relates to a regeneration device and an air conditioning device that utilize air conditioning by the solid elastic heat quantity effect.

Background Art

[0002] Air conditioning by the solid elastic heat quantity effect is a new emerging air conditioning technology that is clean and environmentally friendly. By applying or removing stress on a solid elastic heat quantity material, a phase change or reverse phase change is generated therein to generate heat quantity or cold heat, thereby performing air conditioning.

[0003] In an air conditioning device manufactured based on this principle, when a driving device applies stress to a solid elastic heat quantity material, a large amount of solid elastic heat quantity materials are required to generate sufficient heat quantity or cold heat. In actual applications, solid elastic heat quantity materials usually design and join a plurality of solid elastic heat quantity material units, and displacement easily occurs in the plurality of solid elastic heat quantity material units during the process of the driving device applying stress, resulting in blockage of the flow path. As a result, the heat transfer efficiency of the heat transfer fluid decreases. Further, after displacement occurs in the solid elastic heat quantity material unit, the driving device may not be able to completely apply stress to the surface of the plate-shaped solid elastic heat quantity material during the stress loading process. Therefore, some solid elastic heat quantity material units cannot undergo a phase change, resulting in a decrease in the generated heat quantity and cold heat, and causing a situation where the air conditioning efficiency decreases.

[Brief explanation of the drawing]

[0017] [Figure 1] This is a side view of the regeneration device according to the present invention. [Figure 2] This is a schematic diagram illustrating the deposition of heating and cooling materials using the solid elastic caloric effect according to the present invention. [Figure 3] This is a detailed cross-sectional view of a heating and cooling material utilizing the solid elastic caloric effect according to the present invention. [Modes for carrying out the invention]

[0018] To further clarify the technical problem, technical solution, and beneficial effects that this application aims to solve, the application will be described in more detail below with reference to the drawings and embodiments. The specific embodiments described herein are for interpretation purposes only and are not intended to limit the application.

[0019] As shown in Figure 1, the regeneration device utilizing the solid elastic caloric effect for heating and cooling according to the present invention includes a fixing mechanism 1, a solid elastic caloric effect heating and cooling material 2 having perforations arranged sequentially on the fixing mechanism 1, a drive mechanism 3, and a sleeve 4, wherein the fixing mechanism 1 and the drive mechanism 3 are installed inside the sleeve 4. The drive mechanism 3 includes a movable pressurizing head 31 provided with a through hole 311, and the movable pressurizing head 31 extends into the fixed mechanism 1 to apply or remove stress to the heating and cooling material 2 due to the solid elastic calorific effect. The perforations in the heating and cooling material 2 due to the solid elastic caloric effect form passages by arrangement, and these passages communicate with the through holes 311. These passages are used to exchange the heat generated in the heating and cooling material 2 due to the solid elastic caloric effect when a heat transfer fluid flows through them.

[0020] In this embodiment, as shown in FIG. 2, the fixing mechanism 1 is used to fix the heating and cooling material 2 based on the solid elastic caloric effect, which is arranged and deposited in sequence according to the cross-section. The fixing method of the fixing mechanism 1 is not limited. As long as there is sufficient space for the movable pressure head 31 to easily extend at one or both ends after fixing, preferably, the fixing mechanism is a cylindrical shape, a cube, a cuboid, etc. with a hollow interior, and its inner wall is in close contact with the heating and cooling material 2 based on the solid elastic caloric effect. In this way, in the assembly process, it is only necessary to be able to put the heating and cooling material 2 based on the solid elastic caloric effect into the fixing mechanism. Note that the heating and cooling material 2 based on the solid elastic caloric effect may be in a block shape, a plate shape, or a sheet shape, and its shape is not limited.

[0021] Note that the fixing mechanism 1 is preferably made of a polymer material. Specifically, it may be nylon, polyester, hard silica gel, resin, etc., and preferably, it is polytetrafluoroethylene. In the process of the driving mechanism 3 applying stress, the heating and cooling material 2 based on the solid elastic caloric effect expands in the lateral direction. By being made of a polymer material, it can accommodate the expansion amount and play a role in buffering against the lateral pressure. On the other hand, since the heat conductivity of the polymer material is low, it can also prevent the heat dissipation of the heat transfer fluid.

[0022] In this embodiment, the heating and cooling material 2 based on the solid elastic caloric effect is provided with perforations. During deposition, the perforations are aligned to form a passage for the heat transfer fluid to flow. Further, in order to facilitate assembly, an alignment member may be provided on the inner wall of the fixing mechanism. Specifically, it may be a notch, an irregular shape, or an external position limiting member. Also, each heating and cooling material 2 based on the solid elastic caloric effect may be provided with an alignment mark corresponding to the alignment member. In a preferred embodiment, as shown in FIG. 3, preferably, an irregular shape is provided, and the specific shape is not limited. Note that the shape of the perforation is not limited and may be one or more of a square shape, a circular shape, a radial shape, or a spiral shape. Preferably, in order to improve the heat exchange capacity, a radial shape or a spiral shape is selected.

[0023] Furthermore, the cross-sectional shape of one end of the movable pressurizing head 31 of the drive mechanism 3 that contacts the heating and cooling material 2 due to the solid elastic caloric effect is the same as the cross-sectional shape of the heating and cooling material 2 due to the solid elastic caloric effect. The through-hole 311 is located at the center of the movable pressurizing head 31 and is coaxial with the passage. In this embodiment, the movable pressurizing head 31 conforms to the cross-sectional shape of one end of the heating and cooling material 2 due to the solid elastic caloric effect where stress is applied. For example, when the shapes are the same and stress is applied, the movable pressurizing head 31 overlaps with the cross-section of the heating and cooling material 2 due to the solid elastic caloric effect. Or when the shapes of both are different, the cross-section of the movable pressurizing head 31 completely covers the cross-section of the heating and cooling material 2 due to the solid elastic caloric effect, ensuring that the heating and cooling material 2 due to the solid elastic caloric effect completely undergoes a phase change when the drive mechanism 3 loads stress, thereby improving the efficiency of heating and cooling. Also, by providing the through-hole 311 at the center of the movable pressurizing head 31, it is possible to make the heat transfer fluid in the passage uniform at each angle and ensure that it flows out from the through-hole 311 at the same flow rate.

[0024] Note that the thickness of the plate-shaped heating and cooling material due to the solid elastic caloric effect is 0.01 - 100 mm, preferably 0.1 - 10 mm, and more preferably 0.15 - 0.3 mm.

[0025] In this embodiment, the sleeve 4 is used to fix the fixing mechanism 1 and the drive mechanism 3. That is, in actual applications, the assembled fixing mechanism 1 and drive mechanism 3 are arranged in the sleeve 4. On the one hand, it plays the role of fixing each mechanism, and on the other hand, it is easy to replace its members.

[0026] In one embodiment, as shown in Figure 1, the drive mechanism 3 includes a movable pressurizing head 31, a first distribution pressurizing head 32, and a drive pressurizing head 33. One end of the movable pressurizing head 31 is fixed to the first distribution pressurizing head 32, and a distribution pipe 321 is provided in the first distribution pressurizing head 32. The distribution pipe 321 communicates with a through hole and is used to discharge heat transfer fluid. The other end of the first distribution pressurizing head 32 is fixed to the drive pressurizing head 33, and the other end of the drive pressurizing head 33 is fixed to the drive unit. The distribution pipe 321 includes a main pipe and a first branch pipe and a second branch pipe, each communicating with the main pipe. The main pipe communicates with a through hole, the first branch pipe is used to discharge heat transfer fluid, and the second branch pipe is used to bring heat transfer fluid in.

[0027] To increase load strength, the movable pressure head can be made of high-strength tungsten steel. To ensure the flow of the medium in the flow path, a seal ring is provided at the connection between the pressure rod and the pressure head to form a sealed flow path and prevent leakage of the medium.

[0028] In some embodiments, to reduce the frictional force between the first distribution pressure head 32 and the drive pressure head 33 in the drive mechanism and the sleeve 4, a slide rail 41 is provided inside the sleeve 4, and guide portions are provided on the surfaces of the first distribution pressure head 32 and the drive pressure head 33 that fit into the slide rail 41, and the guide portions are used to slide along the slide rail 41 when the first distribution pressure head 32 and the drive pressure head 33 in the drive mechanism 3 are loading or unloading stress. In some embodiments, the slide rail that contacts the fixing mechanism 1 on the inner wall of the sleeve 4 may be provided with an engaging member for fixing the fixing mechanism 1, and the slide rail may not be provided in the portion of the inner wall of the sleeve 4 that overlaps with the fixing mechanism 1, and the slide rail may be provided only at the open end of the sleeve 4.

[0029] In some embodiments, in order to achieve heat exchange, that is, to quickly transfer the heat transfer fluid that has absorbed heat or cold to the heat exchanger, a flow divider is provided at the other end of the fixed mechanism 1, and a fluid passage hole is provided at the flow divider, the fluid passage hole is coaxial with the passage, and the role of the fluid passage hole is the same as the role of the through hole of the movable pressurizing head 31.

[0030] Furthermore, the fixing mechanism 1 further includes a second distribution pressurizing head, which includes a main line, a first branch line, and a second branch line, the main line communicating with the fluid passage, the first branch line, and the second branch line, respectively. Their specific roles are described by referring to the main line, first branch line, and second branch line of the first distribution pressurizing head.

[0031] Embodiments of the present invention further provide a heating and cooling system, the heating and cooling system including the above-mentioned regeneration device and heat exchange device, The regeneration device is connected to the heat exchanger via piping and is used to transfer heat transfer fluid, which has been heated after heat absorption or cooled after heat release, to the heat exchanger for heat exchange. The piping can be inserted into the first and second distribution lines of the first and second distribution pressure heads, respectively, thereby allowing the heat transfer fluid to flow into the heat exchanger for heat exchange.

[0032] In this embodiment, although not shown in the drawings, the pipeline serves as a vessel for the fluid flow, connected to the heat exchanger of the equipment, and plays a role in allowing the fluid to flow into the heat exchanger and releasing heat or cold.
