Description

Technical Field

[0001] This application belongs to the technical field of space temperature control, and specifically relates to a solid-state cartridge refrigeration and heating device. Background Art

[0002] The development of space refrigeration and heating technology is an important guarantee for people to maintain a high-quality life in modern times. Common space refrigeration and heating systems include using air conditioners to lower or raise the temperature of the surrounding space, using refrigerators to store items inside at low temperatures, and using warm air equipment to maintain a constant temperature in a local space.

[0003] In the prior art, the control of space temperature is often achieved through gas compression refrigerators. However, under the strategic background of sustainable development, this refrigeration and heating method exposes many problems: First, the refrigerants used in gas compression refrigerators (such as chlorine- and bromine-containing refrigerants) will be discharged into the environment in large quantities, resulting in a sharp decline in the ozone content in the atmosphere and causing irreversible damage to the atmosphere; while existing environmentally friendly refrigerants (such as fluorine- and ammonia-containing refrigerants) have reduced environmental hazards, but they have the disadvantages of being flammable and explosive, and there are significant safety risks during use. Second, the energy conversion rate of refrigeration and heating through gas compression is very low, and most of the electrical energy cannot be effectively converted, resulting in energy waste.

[0004] Solid-state cartridge refrigeration and heating technology is a new type of space temperature control technology that is efficient and environmentally friendly. This technology induces a phase change in the material by mechanically deforming the cartridge material (hereinafter simply referred to as "cartridge material"), thereby generating latent heat release and absorption to achieve the technical purpose of regulating the temperature of the target object. Among them, cartridge materials refer to solid materials with a cartridge (thermal) effect, such as shape memory alloys, natural rubbers, synthetic polymers, plastic crystals, etc.; among them, due to shape memory alloys (such as nickel-titanium alloys, copper-aluminum-manganese alloys, nickel-manganese-copper-cobalt alloys, nickel-iron-gallium alloys, etc.) having extremely high phase change entropy values and material energy efficiency ratios, they are widely used in solid-state cartridge refrigeration technology.

[0005] The inventor found that the energy efficiency ratio generated by existing solid-state cartridge refrigeration prototypes during actual operation is much smaller than the material energy efficiency ratio of the cartridge material, that is, there are problems of low energy utilization rate and low conversion rate in solid-state cartridge refrigeration technology. Specifically: Existing solid-state cartridge refrigeration prototypes generally use linear drive mechanisms (such as hydraulic push rods, linear push rods, etc.), and during the unloading (recovery of deformation) process of the cartridge material, the linear drive mechanism needs to input electrical energy to retract the indenter, which will increase the power consumption of the linear drive mechanism and lead to the technical defect of reduced energy efficiency ratio of the solid-state cartridge refrigeration prototype.

Detailed implementation manners

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0052] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more, unless otherwise specifically defined.

[0053] Please refer to Figures 1 to 12 together, and now the solid-state spring card refrigeration and heating device provided by this application will be described. The solid-state spring card refrigeration and heating device proposed by this application includes a main shaft 1 and multiple groups of strips 3.

[0054] The main shaft 1 is used to be fixed on a horizontal plane, and its axis is parallel to the up and down direction.

[0055] A turntable 2 is coaxially connected to the upper end of the main shaft 1, and a rotational driving member 21 is drivingly connected to this turntable 2; in actual use, this rotational driving member 21 can drive the turntable 2 to rotate relative to the main shaft 1, and the rotation axis of the turntable 2 coincides with the central axis of the main shaft 1.

[0056] Multiple groups of strips 3 are arranged at intervals around the central axis of the main shaft 1 on the outside of the main shaft 1. Each group of strips 3 among them includes one or more strips 3 arranged side by side on a horizontal plane and all made of spring card material; in this embodiment, a group of strips 3 includes nineteen strips 3 arranged side by side on a horizontal plane, and there is a gap between any two strips 3.

[0057] It should be noted that the geometric shapes adopted by the strip 3 proposed in this embodiment include cylindrical, cubic, cuboid, circular tube, and rectangular tube shapes, and the elastic card materials selected for it include shape memory alloy, natural rubber, synthetic polymer, and plastic crystal; when the elastic card material selected for the strip 3 is a shape memory alloy, it can be one of nickel-titanium alloy, copper-aluminum-manganese alloy, nickel-manganese-titanium alloy, nickel-titanium-cobalt alloy, nickel-titanium-copper-cobalt alloy, and nickel-iron-gallium alloy.

[0058] There is a lifting member 4 between each group of strips 3 and the main shaft 1. This lifting member 4 is adapted to be connected to each corresponding strip 3 and also abuts against the lower side surface of the turntable 2; in special cases, there is a connection relationship between the lifting member 4 and the upper end of the strip 3 to ensure the unity of the relative positions of the lifting member 4 and the strip 3.

[0059] Among them, the lower side surface of the turntable 2 has a number of convex portions 22 adapted to be connected to the lifting member 4; as the turntable 2 rotates, each convex portion 22 is adapted to abut against any one of the lifting members 4, so that the lifting member 4 moves downward under pressure.

[0060] During the actual use process, each strip 3 has an unloading state when the lifting member 4 abuts against the lower side surface of the turntable 2, and a loading state when the lifting member 4 abuts against the convex portion 22.

[0061] During the process of the strip 3 switching from the unloading state to the loading state, the elastic card material undergoes compressive deformation; based on this, the strip 3 in the loading state can release heat and increase the temperature at the location of this group of strips 3.

[0062] During the process of the strip 3 switching from the loading state to the unloading state, the elastic card material recovers its deformation; based on this, the strip 3 in the unloading state can absorb heat and reduce the temperature at the location of this group of strips 3.

[0063] Since the solid-state elastic card refrigeration and heating device provided in this embodiment applies force by rotating the turntable 2, it can greatly reduce the number of mechanical transmission devices (compared with the existing linear drive mechanism), thereby reducing the mechanical energy and electrical energy losses. And, since multiple groups of strips 3 are distributed in a ring around the main shaft 1 in space, the overall space occupation is also greatly reduced, making the overall structure of the device more compact; at the same time, compared with the traditional elastic card material that needs to wait for heat dissipation before using the cooling capacity, since the strips 3 are classified by groups and the intermittent refrigeration of multiple groups of strips 3 can be superimposed into continuous refrigeration, the efficiency and refrigeration power are greatly improved.

[0064] In the embodiment of the present application, by rotating the driving member 21, the turntable 2 can be driven to rotate, so that a part of the strip 3 abuts against the lower side surface of the turntable 2 through the lifting member 4, and another part of the strip 3 abuts against the convex portion 22 through the lifting member 4; wherein, each strip 3 corresponding to the lifting member 4 abutting against the lower side surface of the turntable 2 is in an unloading state, and each strip 3 corresponding to the lifting member 4 abutting against the lower side surface of the convex portion 22 is in a loading state; moreover, the strip 3 in the loading state releases heat, and the strip 3 in the unloading state absorbs heat, and this part of the energy change can be absorbed by most of the heat-conducting medium, so as to act on the space refrigeration and heating process.

[0065] Compared with the prior art, the solid elastic card refrigeration and heating device provided in this embodiment can avoid the application of a linear driving mechanism, thereby avoiding the energy consumption caused by retracting the indenter and improving the energy efficiency ratio of the refrigeration and heating process.

[0066] In some embodiments, as Figure 5 shown, each group of strips 3 further includes a cylinder 5 sleeved outside the corresponding strip 3; the lower end of the cylinder 5 is connected with a base 51 connected to each strip 3, and the base 51 also has a discharge port 511 communicated with the cylinder 5. On the basis that the cylinder 5 surrounds the strip 3, the main structure of the cylinder 5 can realize the lateral limitation of the energy generated by the strip 3, and avoid the rapid dissipation of the heat and cold generated by the strip 3 in the space.

[0067] Based on this, in this embodiment, the lifting member 4 includes a piston 41 and a transmission seat 42.

[0068] The piston 41 is slidably inserted into the cylinder 5 in the up and down direction, and is located above the strip 3 and abuts against the upper end of each strip 3; moreover, when the piston 41 is inserted into the cylinder 5, the outer peripheral wall of the piston 41 is in contact with the inner peripheral wall of the cylinder 5 to realize the sealing of the cylinder 5 and avoid the escape and dissipation of the heat and cold generated by the strip 3 at the upper end of the cylinder 5. The piston 41 also has a plurality of first through holes 411 penetrating in the up and down direction and communicating with the inside of the cylinder 5.

[0069] The transmission seat 42 is arranged above the piston 41 and is connected to the piston 41; moreover, the upper end of the transmission seat 42 is in contact with the lower side surface of the turntable 2, and it also has a feed port 421 communicated with each first through hole 411.

[0070] Specifically, this feed port 421 penetrates from the lower end surface of the transmission seat 42 to the outer peripheral wall of the transmission seat 42 for the medium for heat exchange to enter and transfer; in this embodiment, the penetration area of the feed port 421 with the outer peripheral wall of the transmission seat 42 is smaller than the penetration area of the feed port 421 with the lower end surface of the transmission seat 42, so as to realize the injection of the medium in the small-diameter area and the communication with the plurality of first through holes 411.

[0071] In some embodiments, such as Figure 3 , Figure 5 , Figure 11 and Figure 12 shown, the solid-state cartridge refrigeration and heating device further includes a base 6; this base 6 is used to be fixed on a horizontal plane, and its upper end surface is fixedly connected to the main shaft 1, that is to say, the main shaft 1 is fixed on the horizontal plane through the base 6.

[0072] The upper end surface of the base 6 has a plurality of receiving grooves 61 arranged at intervals around the main shaft 1 and corresponding to the multiple groups of strips 3 one by one, and the aforementioned multiple cylinders 5 are inserted into the multiple receiving grooves 61 one by one.

[0073] Each inner wall of the receiving groove 61 has a reserved hole 62; when the cylinder 5 is inserted into the receiving groove 61 and the base 51 abuts against the bottom of the receiving groove 61, the reserved hole 62 is adapted to communicate with the corresponding discharge port 511 to realize the discharge of the medium after heat exchange.

[0074] In some embodiments, such as Figure 3 , Figure 5 and Figure 11 shown, there is a discharge pipe 7 between each cylinder 5 and the base 6; one end of this discharge pipe 7 is communicated with the discharge port 511, and the other end passes through the reserved hole 62 and extends out to be used for directing the discharge of the medium and avoiding the outflow of the medium from the gap between the cylinder 5 and the base 6, thereby avoiding the waste of the medium (and the heat or cold it carries).

[0075] In some embodiments, such as Figure 8 shown, the discharge port 511 adopts a frustum structure extending in the up and down direction, and the cross-sectional circular area of the discharge port 511 gradually decreases from top to bottom; the discharge pipe 7 is fixedly connected to the lower end of the discharge port 511, and it penetrates through the cylinder 5 along the radial direction of the cylinder 5 and extends out.

[0076] Moreover, a funnel-shaped connecting piece 71 is connected to the connecting end of the discharge pipe 7 and the discharge port 511; after the discharge pipe 7 is inserted into the discharge port 511 and extends out, the outer peripheral surface of the connecting piece 71 is in contact with the inner peripheral wall of the discharge port 511, so that the substances in the discharge port 511 can enter the discharge pipe 7 through the connecting piece 71 and restrict the discharge pipe 7 from moving out of the discharge port 511.

[0077] In some embodiments, such as Figures 8 to 10 shown, each strip 3 adopts a tubular structure with a hollow interior and open ends at both ends.

[0078] The aforementioned piston 41 further has a plurality of second through holes 412 penetrating in the up and down direction and corresponding to and communicating with the multiple strips 3 one by one; it should be noted that this second through hole 412 is also communicated with the aforementioned feed port 421 to be adapted to introduce the injected medium into the interior of the strip 3.

[0079] The upper side surface of the base 51 has a plurality of third through holes 512 that communicate with the discharge port 511 and correspond to and communicate with the plurality of strips 3 one by one, and a fourth through hole 513 that communicates with the discharge port 511 and communicates with the inside of the cylinder body 5; in this embodiment, the base 51 includes a hollow body with an upward opening, and a top cover that is detachably connected to the open end of the body and is provided with the third through hole 512 and the fourth through hole 513; wherein, the opening of the body can allow the aforementioned connecting member 71 to pass through. The purpose of such a design is that when the body and the top cover are separated, it is more convenient to adjust and replace the discharge pipe 7.

[0080] That is to say, the discharge port 511 is a cavity that penetrates from the inside of the base 51 to the outer peripheral wall of the base 51; based on this, the base 51 communicates with the inside of the cylinder body 5 through the fourth through hole 513 to realize the discharge of the medium inside the cylinder body 5 (not inside the strip 3).

[0081] It should be added that the main structure of each strip 3 can adopt one of a straight shape, a spiral shape, and a multi-section bent shape; in this embodiment, the strip 3 adopts a straight shape for easy loading during production and installation; when the structure of the strip 3 adopts a non-straight shape, the occupancy of the strip 3 inside the cylinder body 5 increases to ensure the heat exchange effect when the medium passes through the cylinder body 5 and the strip 3.

[0082] In some embodiments, such as Figure 6 and Figure 7 shown, the inside of the cylinder body 5 has a plurality of stabilizers 8 arranged at intervals in the up and down direction; each stabilizer 8 is connected to the cylinder body 5, and has a plurality of positioning holes 81 adapted to allow the corresponding plurality of strips 3 to pass through one by one.

[0083] By adopting the above technical solution, each stabilizer 8 can support the corresponding strip 3, avoiding the occurrence of irregular buckling of the strip 3; that is to say, when the strip 3 is in the unloaded state, the part of the strip 3 above the upper stabilizer 8, between two adjacent stabilizers 8, and below the lower stabilizer 8 all undergoes buckling in the horizontal direction, making the area where elastic deformation occurs on the strip 3 regular, and the corresponding heat exchange phenomenon arrangement area more uniform.

[0084] In some embodiments, such as Figures 1 to 5 shown, a number of balls 422 are provided on the upper end surface of the transmission seat 42; these balls 422 are in contact with the lower side surface of the turntable 2, and the balls 422 are adapted to roll relative to the transmission seat 42 to optimize the transition of the transmission seat 42 between the turntable 2 and the convex portion 22, thereby reducing the occurrence of noise and irregular vibration.

[0085] In some embodiments, such as Figure 4As shown, the rotation driving member 32 is a rotation motor fixedly arranged at the upper end of the main shaft 1; in this embodiment, a groove 11 is formed on the upper end surface of the main shaft 1, and the rotation driving member 21 is a rotation motor fixedly arranged in the groove 11; the power output axis of this rotation motor is parallel to the up and down direction, and its power output end is connected to the turntable 2 to realize the effective driving of the turntable 2 and the rotational connection relationship between the turntable 2 and the main shaft 1.

[0086] In some embodiments, as Figures 1 to 3 shown, the number of groups of the strips 3 is an even number, and multiple groups of strips 3 are arranged at equal intervals with the main shaft 1 as the axis; in this embodiment, there are six groups of strips 3, and they are classified according to symmetry along the main shaft 1, and the six groups of strips 3 can be evenly divided into three categories of mutually symmetric strips 3.

[0087] There are several driving arms 9 between two strips 3 that are axially symmetric with the main shaft 1; each driving arm 9 is rotatably connected to the outer wall of the main shaft 1 (the rotation axis is parallel to the horizontal plane and also perpendicular to the arrangement direction of the two strips 3), and its left and right ends are respectively hinged to two lifting members 4 (the hinge axis is parallel to the rotation axis of the driving arm 9, that is, parallel to the horizontal plane and also perpendicular to the arrangement direction of the two strips 3).

[0088] Moreover, the number of the convex portions 22 is half of the number of groups of the strips 3; when there are multiple convex portions 22, the multiple convex portions 22 are distributed at equal intervals in the circumferential direction of the turntable 2. In this embodiment, there are three convex portions 22, and the three convex portions 22 can simultaneously abut against three lifting members 4; at the same time, the remaining three lifting members 4 abut against the lower side surface of the turntable 2.

[0089] That is to say, when one group of strips 3 is in the unloading state, the other group of strips 3 that is axially symmetric with it about the main shaft 1 is in the loading state.

[0090] By adopting the above technical solution, during the process of the strip 3 switching from the loading state to the unloading state, this strip 3 can generate unloading work, and this unloading work can act on the driving arm 9 and be transmitted to the other group of strips 3 that is axially symmetric with it about the main shaft 1, so as to effectively utilize the unloading work of the elastic card material from elastic deformation to restoration of the original state, thereby improving the energy efficiency ratio of the solid-state elastic card refrigeration and heating equipment.

[0091] The above content is only the preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this application shall be included within the protection scope of this application.
