[0043] Specifically, power mechanism 30 can be motor, hydraulic power element, pneumatic power element and the like.
[0044] The high-power refrigeration and heating device provided in the embodiment, compared with prior art, can drive multiple solid-state elastic card regenerator 10 suitable for elastic card material operation to refrigerate or heat by multiple linkage transmission mechanism 20 using a set of power mechanism 30, and then multiple solid-state elastic card regenerator 10 is gathered, enough heating capacity or refrigeration capacity can be obtained;It can not only avoid the problem that material cannot be sustained due to the design of solid-state elastic card regenerator 10 being too large, but also provide enough heating capacity or refrigeration capacity to meet the demand in actual application.
[0045] As shown in Figures 1 to 5 The utility model provides a kind of specific implementation mode on the basis of first embodiment as follows:
[0046] In order to facilitate the derivation of refrigerating capacity or heating capacity, the high-power refrigerating and heating device further comprises a heat-conducting medium collecting mechanism connected with the plurality of solid-state snap-action regenerators 10 respectively to supply the heat-conducting medium into the plurality of solid-state snap-action regenerators 10 respectively and to collect the derived heat-conducting medium after the refrigeration or heating by the solid-state snap-action regenerators 10 and then exchange heat.
[0047] The heat-conducting medium collecting mechanism can be a pipeline system composed of pipelines, busbars, distributors, pumping assemblies, heat-conducting medium storage assemblies and the like. The heat-conducting medium collecting mechanism is connected with devices requiring heat or cold such as heat exchangers to form a circulation to realize the transmission and circulation of heat.
[0048] As shown in Figure 2 In some specific embodiments, the multi-kinetic transmission mechanism 20 comprises a rotating main shaft 21 connected with the power mechanism 30 and a plurality of power output nodes arranged at intervals on the rotating main shaft 21 and connected with corresponding solid-state snap-action regenerators 10 respectively. In this way, the power mechanism 30 can be used to input power to the rotating main shaft 21, and the plurality of power output nodes can be used to input power to the corresponding solid-state snap-action regenerators 10 respectively. The part where the main shaft support 26 is connected with the power mechanism is the power input end, and the part where the power output node is connected with the solid-state snap-action regenerator 10 is the power output end.
[0049] The rotating main shaft 21 can be connected with one power mechanism 30 at one end or connected with one power mechanism 30 at each end. That is, one power mechanism 30 can be used to input power according to the needs, or two power mechanisms 30 can be used to input power, and the two power mechanisms 30 can be of the same power or type or different power or type.
[0050] In order to limit the position of the rotating main shaft 21, the multi-kinetic transmission mechanism 20 further comprises a main shaft support 26 fixed on a stable working surface and fixed relative to the solid-state snap-action regenerators 10, that is, the positions of the two are fixed relative to each other, and the rotating main shaft 21 is connected with the main shaft support 26 to ensure the stable rotation of the rotating main shaft 21, reduce the shaking of the rotating main shaft 21, and avoid the situation that the power transmission on the rotating main shaft 21 cannot reach the solid-state snap-action regenerators 10.
[0051] In order to ensure the stability of the rotating main shaft 21 when the power output nodes output power and generate excessive load, and at the same time reduce the friction loss, the rotating main shaft 21 and the main shaft support 26 are connected through a plurality of second bearings, and the second bearings are located between adjacent power output nodes.
[0052] Specifically, as shown in Figure 3As shown, in some embodiments, the power output section includes an eccentric cam 23, a first bearing 22, a ring 24, and a drive rod 25, the eccentric cam 23 is fixed on the rotating spindle 21; the first bearing 22 is sleeved on the outer circle of the eccentric cam 23; the ring 24 is clamped on the outside of the first bearing 22; the drive rod 25 is fixedly connected with the ring 24 at one end, and is connected with the solid-state elastic snap regenerator 10 at the other end.
[0053] Through this structure, the rotating power of the rotating spindle 21 can be converted into the pulling and pressing power on the drive rod 25, the power input into the solid-state elastic snap regenerator 10 is realized, the elastic snap material in the solid-state elastic snap regenerator 10 is compressed to cause phase change and release heat, and the phase change is unloaded to recover heat absorption; and the first bearing 22 can reduce the friction between the eccentric cam 23 and the ring 24.
[0054] The first bearing 22 and the second bearing can be bearing members such as ball bearings, spherical bearings, air bearings, etc., or other members capable of bearing.
[0055] In an embodiment, the first bearing 22 adopts a ball bearing, which can bear a load of 100,000 N, and the second bearing adopts a spherical bearing, which can bear a load of 46,713 N. In actual application, the high-power refrigeration and heating equipment is applied in practice, for example, in air conditioners, for an air conditioner with an energy consumption of one match (734 W), the energy consumption ratio COP = refrigerating capacity / consumed power, according to the COP of 3-3.5, the refrigeration power of the equipment is about 2400 W, according to the characteristics of the solid-state elastic snap material, the pressure during phase change is 900000000 Pa, so the pressure output by a single power output section is about 45,000 N. In this embodiment, the ball bearing is used as the first bearing to bear the pressure to the greatest extent, and the spherical bearing is used as the second bearing to ensure the stability of the rotating spindle 21.
[0056] Further, the eccentric cam 23 is a disc-shaped wheel structure, and an eccentric shaft hole is arranged inside, an inner key groove is arranged on the shaft hole, the rotating spindle 21 and the corresponding part of each eccentric cam 23 are provided with an outer key groove, and the eccentric cam 23 and the rotating spindle 21 are fixedly connected through the key strip clamped between the inner key groove and the outer key groove, so as to ensure the stability of the structure.
[0057] The phase angle between the adjacent outer key grooves on the rotating spindle 21 is 360 / n, that is, all the outer key grooves are uniformly distributed in the lateral projection of the rotating spindle 21, wherein n is the number of the power output sections. In this way, when the rotating spindle 21 rotates, the torque is approximately the same, so that different solid-state elastic snap regenerators 10 are rotated in turn, which can not only ensure the stability of the structure and the power output, but also reduce the shaking of the rotating spindle 21, thereby reducing mechanical wear and noise, and also reducing friction loss and improving energy utilization.
[0058] like Figure 3 As shown, in some specific embodiments, the hoop 24 includes a first half-ring 241, a second half-ring 242, and a half-ring fastener 243. The first half-ring 241 is fixedly connected to the drive rod 25 by means of threaded connection, welding, or integral molding. The second half-ring 242 is engaged with the first half-ring 241 and surrounds the outer ring of the first bearing 22. The half-ring fastener 243 is connected to the first half-ring 241 and the second half-ring 242 respectively to fasten the first half-ring 241 and the second half-ring 242 to the outer ring of the first bearing 22, so as to avoid relative movement between the hoop 24 and the outer ring of the first bearing 22, which would lead to problems such as power loss. The inner sides of the first half-ring 241 and the second half-ring 242 are provided with receiving grooves for accommodating the outer ring of the first bearing 22, so as to fasten the first half-ring 241 and the second half-ring 242 to the outer ring of the first bearing 22 by means of the half-ring fastener 243, so as to avoid the outer ring of the first bearing 22 from contacting the hoop 24.
[0059] Specifically, the semi-ring fastener 243 can be a threaded fastener, a snap fastener, or a pin fastener, etc.
[0060] Furthermore, the eccentric cam 23 and the inner ring of the first bearing 22 are interference-fitted to avoid relative movement between the eccentric cam 23 and the inner ring of the first bearing 22, which could lead to power loss and other problems.
[0061] like Figure 3 As shown, in some specific embodiments, the solid spring-loaded regenerator 10 includes a fixed sleeve 11, multiple solid spring-loaded material plates 12, a pressure head 13, a plug structure 14, and a medium conveying pipeline assembly. Multiple solid spring-loaded material plates 12 are stacked within the fixed sleeve 11, and each solid spring-loaded material plate 12 contains perforations. These perforations, when stacked, form a flow cavity for the passage of a heat-conducting medium. The pressure head 13 is slidably disposed at one end of the fixed sleeve 11 and connected to a drive rod 25. Driven by the drive rod 25, it loads or unloads the multiple solid spring-loaded material plates 12, causing them to deform and thus generate heat or cool. The plug structure 14 plugs the other end of the fixed sleeve 11 and abuts against the solid spring-loaded material plates 12, limiting the axial movement of the solid spring-loaded material plates 12. The medium conveying pipeline assembly communicates with the flow cavity and the heat-conducting medium collection mechanism, and is connected to the heat-conducting medium collection mechanism for the input and output of the heat-conducting medium.
[0062] It should be noted that the shape of the pressure head 13 is the same as the cross-sectional shape of the solid spring-loaded material plate. This way, when the pressure head applies stress to the solid spring-loaded material plate, it avoids simultaneously applying force to the protrusion, thus increasing the energy efficiency of the cooling and heating device. To increase the strength of the load, the pressure head can be made of high-strength ceramic or tungsten steel.
[0063] The shape and number of the perforations can be selected as desired. Preferably, the perforations are polygonal, radial, circular or square.
[0064] In one embodiment, the solid elastic material plates 12 are in the shape of a plate, and since each plate is independently stressed, even if some of the solid elastic material plates 12 crack during loading and unloading, the crack will not spread to other solid elastic material plates, i.e., the solid elastic material will not fail as a whole, thereby improving the service life of the solid elastic material.
[0065] In one embodiment, the thickness of the solid elastic material plates is 0.01-100 mm, preferably 0.1-10 mm, and more preferably 0.15-0.3 mm.
[0066] In actual applications, in order to avoid misalignment of the solid elastic material plates 12 after stacking and during use, or to avoid the perforations being misaligned to form a smooth flow cavity, a limiting structure can be provided between the solid elastic material plates 12 and the fixed sleeve 11 to limit the rotation between the solid elastic material plates 12 and the fixed sleeve 11.
[0067] The limiting structure can be a limiting structure formed by the shapes of the solid elastic material plates 12 and the fixed sleeve 11, or an interference fit between the solid elastic material plates 12 and the fixed sleeve 11, or a separate limiting member provided in the fixed sleeve 11.
[0068] In one embodiment, the inner wall of the fixed sleeve 11 is engaged with the solid elastic material plates, i.e., the shape of the inner wall of the fixed sleeve 11 is the same as that of the solid elastic material plates and there is a gap or the solid elastic material plates internally engage the inner wall of the fixed sleeve 11. For example, the shape of the inner wall of the fixed sleeve 11 and the shape of the solid elastic material plates can both be irregular polygons, polygons, squares, etc. containing angles, and can be engaged with each other and are not easy to rotate. In the embodiments of the present application, the shape of the inner wall of the fixed sleeve 11 and the shape of the solid elastic material plates are preferably hexagonal. In some embodiments, the solid elastic material plates can also internally engage the inner wall of the fixed sleeve 11. Preferably, the inner wall of the fixed sleeve 11 is circular or has an inner angle in the shape of a circular arc, and the solid elastic material plates are square or polygonal to facilitate internal engagement. For example, the inner wall of the fixed sleeve 11 is circular, and the solid elastic material plates are square, with a circle internally engaged in the square; the inner wall of the fixed sleeve 11 is a rectangle with right angles in the shape of a circular arc, and the solid elastic material plates are rectangular or hexagonal.
[0069] In order to fix the position of the stacked solid elastic material plates, the fixing sleeve 11 can also be provided with a limiting part to limit the movement of the solid elastic material plates. For example, a protrusion is arranged along the inner wall of the fixing sleeve 11 in the radial direction, and a recess is arranged at the edge of the solid elastic material plate, so that the protrusion of the fixing sleeve 11 extends into the recess of the stacked solid elastic material plate to limit the position. In another embodiment, the stacked solid elastic material plates are fixed by the limiting part and then fixed with the fixing sleeve 11. For example, a rod-shaped limiting part is inserted into the flow cavity of the stacked solid elastic material plates, and the rod-shaped part is fixed with the fixing sleeve 11 by the fixing device.
[0070] As shown in Figure 5 In a specific embodiment, each solid elastic material plate 12 comprises a groove 122, and a plurality of grooves 122 are stacked to form a space for accommodating the protrusion 113 of the inner wall of the fixing sleeve 11. After the protrusion 113 extends into the space formed by the stacked grooves 122, the gap between the inner wall of the fixing sleeve 11 and the outer surface of the stacked solid elastic material plate 12 forms an additional flow cavity for the flow of the heat-conducting fluid.
[0071] In practical applications, the larger the mass or volume of the solid elastic material, the more heat or cold it generates. Therefore, in order to maximize the absorption of the heat or cold generated by the solid elastic material by the medium, the amount of the solid elastic material needs to be matched with the heat transfer capacity in this embodiment. Generally, a larger flow cavity size can ensure that the solid elastic material of the same mass has a larger specific surface area or volume.
[0072] The groove 122 of each solid elastic material plate and the protrusion 113 of the inner wall of the fixing sleeve 11 are multiple and one-to-one corresponding. The number of the protrusions 113 of the inner wall of the fixing sleeve 11 is the same as the number of the spaces of the grooves 122 formed by the stacking of the solid elastic material plates 12, and the protrusions 113 are respectively embedded in the spaces of the grooves 122 of the solid elastic material plates 12. In this embodiment, the protrusion 12 extends longitudinally along the fixing sleeve 11, and the length thereof is greater than or equal to the length of the stacked solid elastic material plates 12. In this way, the position of the solid elastic material plates 12 can be fixed to a certain extent, and the dislocation thereof can be limited. In order to increase the cross-sectional area of the flow cavity, a plurality of protrusions 113 and grooves 122 can be arranged at different angles. In order to further increase the flow cavity, a serrated structure can be arranged at the edge of the groove 122 of the solid elastic material plate 12 to form a small micro-flow cavity and increase the contact area between the heat-conducting fluid and the solid elastic material, thereby increasing the heat conduction efficiency.
[0073] The groove and the protrusion can be rectangular, arc-shaped, or irregular, which are not limited herein. Preferably, the groove and the protrusion can be designed as rectangular. In this way, the flow cavity formed has an elongated structure, which has a larger contact surface with the solid elastic material on one hand, and the heat-conducting fluid has a faster flow rate and higher heat transfer efficiency due to the blockage of the protrusion on the other hand.
[0074] The gap between the inner wall of the fixed sleeve 11 and the edge of the groove 122 of the solid elastic clamping material plate 12 is 0.1-5mm, preferably 0.5-1mm, at which size the flow resistance is minimized and the flow rate is maximized.
[0075] In actual application, if there is a gap between the inner wall of the fixed sleeve 11 and the solid elastic clamping material plate, the solid elastic clamping material plate may be slightly misaligned, which makes the perforations on the surface of the solid elastic clamping material plate not easily aligned, affecting the flow rate of the heat-conducting fluid in the flow cavity. To solve this problem, the utility model provides an embodiment in which the convex outer surface is in contact with the inner surface of the stacked groove, that is, only the convex and the groove are clamped without leaving a gap, so that a gap is left between the outer edge of the solid elastic clamping material plate and the inner wall of the fixed sleeve 11, thereby limiting the misalignment of the solid elastic clamping material plate.
[0076] It should be noted that the solid elastic clamping material plate will expand in the transverse direction during loading, and therefore, in order to ensure that the solid elastic clamping material plate has enough space to expand, a gap is left between the solid elastic clamping material plate and the inner wall of the fixed sleeve 11. In some applications, a partition is provided on the inner wall of the fixed sleeve 11, for example, a partition film is coated or attached on the inner wall of the fixed sleeve 11, which can be Teflon, POM, nylon, polyester or silicone. On the one hand, the film is soft and can accommodate and buffer the expansion of the solid elastic clamping material plate, and on the other hand, the film has a heat-insulating effect, which can minimize heat loss when the medium exchanges heat through the flow cavity. In addition, when the fixed sleeve 11 and the solid elastic clamping material plate are clamped, the partition can also clasp the solid elastic clamping material plate well. In actual application, Teflon is preferred, and in order to facilitate assembly, the Teflon coating is brushed on the inner wall of the fixed sleeve 11, and then the solid elastic clamping material plate is placed in the lumen of the fixed sleeve 11, which is convenient to operate. The thickness of the solid elastic clamping material plate is 0.01-100mm, preferably 0.1-10mm, and more preferably 0.15-0.3mm.
[0077] In the embodiment of the utility model, a plurality of perforations are provided on the solid elastic clamping material plate, and the perforations are aligned to form a flow cavity after the solid elastic clamping material plates are stacked. In the embodiment in which the inner wall of the fixed sleeve 11 is fixed in the solid elastic clamping material plate, the edge of the solid elastic clamping material plate and the inner wall of the fixed sleeve 11 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. As shown in the figure, the solid elastic clamping unit further comprises a plug body, which is inserted into the flow cavity formed by the perforations, so that the plug body and the inner wall of the perforations form a plurality of micro-flow cavities. Figure 3
[0078] In practical applications, in order to increase the heat transfer efficiency of the medium, the perforations in the embodiment are designed in polygonal, radial, circular or square shapes, and a plug is inserted therein, so that the plug and the inner wall of the perforation form a micro-flow cavity. On the one hand, the flow rate of the medium can be greatly increased, the flow resistance can be reduced, and the heat transfer efficiency can be increased. On the other hand, the greater the volume (mass or volume) of the solid elastic clamping material, the more heat or cold it will generate. Therefore, in order to maximize the heat or cold generated by the solid elastic clamping material to be absorbed by the medium, the amount of the solid elastic clamping material needs to be matched with the heat transfer capacity in the embodiment. Generally, a larger perforation size can ensure that the solid elastic clamping material of the same mass has a larger specific surface area or volume. The design of the large-size perforation with the plug in the embodiment can reduce the flow resistance and increase the flow rate, so that the medium can maximize the absorption of the heat generated by the solid elastic clamping material and improve the heat transfer efficiency. In an optional embodiment, the plug can be used as a limiting piece to fix the position of the solid elastic clamping material plate and limit its movement and misplacement.
[0079] As shown in Figure 3 , in some embodiments, the solid elastic clamping regenerator 10 further comprises an outer sleeve 15, which is sleeved outside the fixed sleeve 11 and is in interference fit with the fixed sleeve 11.
[0080] In practical applications, the assembled fixed sleeve 11 and the pressure head 13 are placed in the outer sleeve 15, which not only serves to fix the various mechanisms, but also facilitates the replacement of the components therein.
[0081] As shown in Figure 3 and Figure 4 , the fixed sleeve 11 comprises a first half cylinder 111, a second half cylinder 112 and a longitudinal seal of the fixed sleeve 11. The first half cylinder 111 has a first half groove inside; the second half cylinder 112 has a second half groove inside and is buckled with the first half cylinder 111 through a positioning structure, so that the first half groove and the second half groove form a cylinder cavity for accommodating a plurality of solid elastic clamping material plates 12; and the longitudinal seal of the fixed sleeve 11 is arranged between the first half cylinder 111 and the second half cylinder 112 to seal the joint between the first half cylinder 111 and the second half cylinder 112.
[0082] In this form, the installation and replacement of the solid elastic clamping material plates 12 can be facilitated, and the overall strength of the structure can also be ensured. In addition, the specific heat capacity of the fixed sleeve 11 can be selected according to its material in order to keep warm.
[0083] It should be noted that the fixed sleeve 11 is preferably made of a high polymer material, which can be nylon, polyester, hard silica gel, resin, etc., and is preferably made of polytetrafluoroethylene. During the stress loading process of the driving mechanism 3, the solid-state refrigeration and heating plate 12 will expand laterally. Using a high polymer material can accommodate the expanded size and buffer the lateral pressure. On the other hand, the high polymer material has poor thermal conductivity, which can also prevent the heat loss of the heat conducting fluid.
[0084] In a specific embodiment, the positioning structure between the first half cylinder 111 and the second half cylinder 112 can be a structure of protrusions and grooves, or a hole or groove structure positioned by fasteners or positioning pins, etc., so as to facilitate the positioning and alignment of the first half cylinder 111 and the second half cylinder 112.
[0085] The cylinder cavity can be a cylindrical, square, rectangular, etc. shaped cavity, and its inner wall is in close contact with the solid-state refrigeration and heating plate 12. Thus, during assembly, the solid-state refrigeration and heating plate 12 can be placed in the fixed sleeve 11. The specific fixing method of the fixed sleeve 11 to the solid-state refrigeration and heating plate 12 can be selected as needed.
[0086] Specifically, as shown in Figure 3 In a specific embodiment, the pressure head 13 includes a moving pressure head 131, a moving pressure head seal, a distribution pressure head 132, and a driving pressure head 133. The moving pressure head 131 is slidingly arranged in the cylinder cavity and abuts against the solid-state elastic material plate 12. The moving pressure head 131 is provided with a first flow hole communicating with the flow cavity. The moving pressure head seal is arranged between the moving pressure head 131 and the inner wall of the cylinder cavity for sealing to prevent leakage of the medium. The distribution pressure head 132 is connected to the end of the moving pressure head 131 away from the solid-state elastic material plate 12 and is provided with a second flow hole and a plurality of distribution holes. The second flow hole communicates with the first flow hole, and the plurality of distribution holes communicate with the second flow hole at one end and are connected to and communicate with the medium conveying pipeline assembly for input and output of the heat conducting medium. The driving pressure head 133 is slidingly arranged in the outer sleeve 15 and is connected to the distribution pressure head 132 and the driving rod 25 to transmit power.
[0087] Preferably, the end of the moving pressure head 131 in contact with the solid-state refrigeration and heating plate 12 has the same cross-sectional shape, and the first flow hole is located at the center of the moving pressure head 131 and coaxial with the cavity. In this embodiment, the end of the moving pressure head 131 in contact with the solid-state refrigeration and heating plate 12 has the same cross-sectional shape and completely covers the cross-section of the solid-state refrigeration and heating plate, which can ensure that the solid-state refrigeration and heating plate completely changes phase during stress loading, thereby improving the efficiency of refrigeration and heating. In addition, by arranging the first flow hole at the center of the moving pressure head 131, the heat conducting fluid in the cavity at each angle can flow out from the first flow hole at the same flow rate.
[0088] In order to increase the loading strength, the dynamic pressure head 131 can be made of high-strength tungsten steel.
[0089] Further, in order to reduce friction and improve the movement accuracy of the dynamic pressure head 131, a sliding rail is arranged in the outer sleeve 15, and the driving pressure head 133 is in sliding fit with the outer sleeve 15 through the sliding rail, so that the driving pressure head 133 slides along the sliding rail during loading or unloading.
[0090] In some embodiments, the sliding rail in the inner wall of the outer sleeve 15 in contact with the fixed sleeve 11 can be provided with a clamping piece for fixing the fixed sleeve 11, or the part of the inner wall of the outer sleeve 15 overlapping the fixed sleeve 11 can not be provided with a sliding rail, and only a guide rail is arranged at the port of the outer sleeve 15.
[0091] In another embodiment, in order to realize heat exchange, that is, to transport the heat-absorbing or cold-absorbing heat-conducting fluid into the heat exchange device as soon as possible, the plug structure 14 arranged at the other end of the fixed sleeve 11 is a water distribution plug, the water distribution plug is provided with a liquid passage, the liquid passage is in communication with the flow cavity, and is connected and communicated with the medium conveying pipeline assembly, so as to input and output the heat-conducting medium.
[0092] In some specific embodiments, as shown in Figure 1 The high-power refrigeration and heating device further comprises a shell 40, the shell 40 covers the solid-state elastic card regenerator 10 and the multi-link transmission mechanism 20 outside; the power mechanism 30 is arranged on the shell 40, and one end of the rotating main shaft 21 penetrates through the shell 40; the multi-link transmission mechanism 20 further comprises a compensation transmission assembly 27, the compensation transmission assembly 27 is arranged between the power mechanism 30 and the rotating main shaft 21, so as to perform compensation transmission. The main shaft support 26 can be fixedly arranged on the shell 40.
[0093] The compensation transmission assembly 27 can be a gear transmission assembly or a chain transmission assembly, which can perform distance compensation.
[0094] Specifically, the power mechanism 30 can be a reduction motor or an internal combustion engine, which can output rotary power.
[0095] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
