Description

Solid-state snap-action cooling and heating device and method

[0001] This application claims priority to the patent entitled: Solid-state snap-action cooling and heating device and method, Chinese patent application No. CN202411058715.2, filed on August 2, 2024, and the patent entitled: Solid-state snap-action cooling and heating device, Chinese patent application No. CN202421864464.2, filed on August 2, 2024. The disclosure of the prior applications is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application belongs to the technical field of space temperature control, and specifically relates to a solid-state snap-action cooling and heating device and method. BACKGROUND

[0003] The development of space cooling and heating technology is an important guarantee for people to maintain a high-quality life in modern times. Common space cooling and heating systems include using air conditioners to lower or raise the temperature of the surrounding space, using refrigerators to store low-temperature items inside, and using warm air equipment to maintain a constant temperature in a local space.

[0004] In the prior art, the control of space temperature is often achieved by gas compression type refrigerators. However, under the background of sustainable development, this cooling and heating method exposes many problems. First, the refrigerants used by gas compression type refrigerators (such as chlorine and bromine-containing refrigerants) are discharged in large quantities into the environment, causing a sharp decrease in atmospheric ozone content and irreversible damage to the atmosphere. Although existing environmentally friendly refrigerants (such as fluorine and ammonia-containing refrigerants) have reduced environmental hazards, they have the disadvantages of being flammable and explosive, which poses a significant safety risk when used. Second, the energy conversion rate of gas compression for cooling and heating is very low, and most of the electrical energy is not effectively converted, resulting in energy waste.

[0005] Solid-state snap-action cooling and heating technology is a new type of space temperature control technology that is highly efficient and environmentally friendly. This technology induces phase change in materials by mechanically deforming snap-action materials (hereinafter referred to as "snap-action materials"), thereby releasing and absorbing latent heat to achieve the technical purpose of regulating the temperature of target objects. Snap-action materials are solid materials that exhibit snap (thermal) effects, such as shape memory alloys, natural rubber, synthetic polymers, and plastic crystals. Shape memory alloys (such as nickel-titanium alloys, copper-aluminum-manganese alloys, nickel-manganese-copper-cobalt alloys, and nickel-iron-gallium alloys) are widely used in solid-state snap-action cooling technology due to their high phase transition entropy and material energy efficiency ratio.

[0006] The inventor finds that the energy efficiency ratio of the existing solid-state snap-action refrigeration prototype in actual work is far less than the material energy efficiency ratio of the snap-action material, that is, there is a problem of low energy utilization rate and low conversion rate in the solid-state snap-action refrigeration technology, specifically: the solid-state snap-action refrigeration prototype generally adopts a linear driving mechanism (such as a hydraulic push rod, a linear push rod, etc.), and in the unloading (restoring deformation) process of the snap-action material, the linear driving mechanism needs to input electric energy to retract the pressure head, which will increase the power consumption of the linear driving mechanism, resulting in the technical defect of reducing the energy efficiency ratio of the solid-state snap-action refrigeration prototype. TECHNICAL PROBLEM

[0059] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the application, the meaning of "multiple" is two or more, and the meaning of "several" is one or more, unless otherwise explicitly specified.

[0060] Please refer to Figures 1 to 12, the solid-state elastic card refrigeration and heating device provided by the present application will be described. The solid-state elastic card refrigeration and heating device proposed by the present application comprises a main shaft 1 and a plurality of strip groups 3.

[0061] The main shaft 1 is used to be fixed on a horizontal plane, and its axial direction is parallel to the up-down direction.

[0062] The upper end of the main shaft 1 is coaxially connected with a rotating disc 2, and a rotating driving member 21 is drivingly connected to the rotating disc 2; in actual use, the rotating driving member 21 can drive the rotating disc 2 to rotate relative to the main shaft 1, and the rotating shaft of the rotating disc 2 coincides with the central shaft of the main shaft 1.

[0063] A plurality of strip groups 3 are arranged on the outer side of the main shaft 1 at intervals around the central axis of the main shaft 1, wherein each strip group 3 comprises one or more strips 3 made of elastic card material and arranged side by side along the horizontal plane; in this embodiment, for example, as shown in Figures 6 and 7, a strip group 3 comprises nineteen strips 3 arranged side by side along the horizontal plane, and there is a gap between any two strips 3, of course, it can also be other quantities, for example, ten, fifteen, twenty, twenty-five, etc.

[0064] It should be noted that the geometric shape of the strip 3 proposed in this embodiment includes cylindrical, cubic, cuboid, circular tube and rectangular tube, and the elastic card material selected includes shape memory alloy, natural rubber, synthetic polymer and plastic crystal; when the elastic card material selected for the strip 3 is shape memory alloy, it can be selected from 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.

[0065] Each group of strips 3 has a lifting piece 4 between the main shaft 1, and the lifting piece 4 is suitable for abutting with each corresponding strip 3 and the lower side of the rotating disc 2; here, the "abutting" includes the abutting relationship and the connecting relationship, and the meaning of "abutting" appearing below is the same as here, and in special cases, the lifting piece 4 and the upper end of the strip 3 have a connecting relationship, so as to ensure the unity of the relative positions of the lifting piece 4 and the strip 3.

[0066] The lower side of the rotating disc 2 has a plurality of protruding parts 22 suitable for abutting with the lifting piece 4; with the rotation of the rotating disc 2, each protruding part 22 is suitable for abutting with any one of the lifting pieces 4, so that the lifting piece 4 is pressed to move downward.

[0067] In actual use, each strip 3 has an unloaded state when the lifting piece 4 abuts against the lower side of the rotating disc 2, and a loaded state when the lifting piece 4 abuts against the protruding part 22. The heat or cold generated by each group of strips 3 is respectively guided out and respectively used for heating or cooling.

[0068] In the process of switching the strip 3 from the unloaded state to the loaded state, the elastic clamping material is compressed and deformed; based on this, the strip 3 in the loaded state can release heat and make the temperature of this group of strips 3 rise.

[0069] In the process of switching the strip 3 from the loaded state to the unloaded state, the elastic clamping material restores the deformation; based on this, the strip 3 in the unloaded state can absorb heat and make the temperature of this group of strips 3 decrease.

[0070] Since the solid-state elastic clamping refrigeration and heating device provided by the embodiment adopts the rotating mode of the rotating disc 2 to apply force, the number of mechanical transmission devices can be greatly reduced (compared with the existing linear driving mechanism), and the mechanical energy and electrical energy loss are reduced. Moreover, since the plurality of groups of strips 3 are distributed in a ring shape around the main shaft 1 in space, the overall space occupation is greatly reduced, so that the overall structure of the device is more compact; at the same time, compared with the traditional elastic clamping material which needs to wait for heat dissipation before using the cold, since the strips 3 are classified according to groups, the intermittent refrigeration of the plurality of groups of strips 3 can be superimposed to continuous refrigeration, so that the efficiency and refrigeration power are greatly improved.

[0071] In the embodiment, the rotating driving member 21 can drive the rotating disc 2 to rotate, so that a part of the strips 3 abut against the lower side of the rotating disc 2 through the lifting members 4, and another part of the strips 3 abut against the protruding portions 22 through the lifting members 4. Each strip 3 corresponding to the lifting member 4 abutting against the lower side of the rotating disc 2 is in an unloading state, and each strip 3 corresponding to the lifting member 4 abutting against the lower side of the protruding portion 22 is in a loading state. The strip 3 in the loading state releases heat, and the strip 3 in the unloading state absorbs heat. The energy change can be absorbed by most of the heat-conducting medium, so as to act on the space refrigeration and heating process.

[0072] Compared with the prior art, the solid-state elastic clamping refrigeration and heating device provided by the embodiment can avoid the application of the linear driving mechanism, thereby avoiding the energy consumption caused by the recovery of the pressure head and improving the energy efficiency ratio of the refrigeration and heating process.

[0073] In some embodiments, as shown in FIG. 5, 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 with each strip 3, and the base 51 further has a discharge port 511 communicating with the cylinder 5. On the basis that the cylinder 5 is arranged around the strip 3, the main structure of the cylinder 5 can realize lateral limitation of the energy generated by the strip 3, so as to avoid the rapid dissipation of the heat and cold generated by the strip 3 in the space.

[0074] Based on this, in the embodiment, the lifting member 4 includes a piston 41 and a transmission seat 42.

[0075] The piston 41 is slidably inserted into the cylinder 5 in the up-down direction, is located at the upper side of the strip 3, and is connected with each strip 3, specifically, abuts against the upper end of each strip 3. When the piston 41 is inserted into the cylinder 5, the outer peripheral wall of the piston 41 is connected with the inner peripheral wall of the cylinder 5, so as to block 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 further has a plurality of first through holes 411 penetrating in the up-down direction and communicating with the inside of the cylinder 5.

[0076] The transmission seat 42 is arranged at the upper side of the piston 41 and is connected with the piston 41. The upper end of the transmission seat 42 abuts against the lower side of the rotating disc 2, and the transmission seat 42 further has a feeding port 421 communicating with each first through hole 411.

[0077] Specifically, the feeding 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 entry and transfer of the medium for heat exchange. In the embodiment, the penetration area of the feeding port 421 and the outer peripheral wall of the transmission seat 42 is smaller than the penetration area of the feeding port 421 and 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.

[0078] Of course, in other embodiments, the lifting member 4 can also be implemented by a resilient structure or the like to achieve the effect of floating when subjected to force, and is not limited to the above embodiments.

[0079] In some embodiments, as shown in FIGS. 1, 3, 5, 11 and 12, the solid-state elastic clamping refrigeration and heating device further comprises a base 6; the base 6 is used to be fixed on a horizontal plane, and the upper end surface thereof is fixedly connected with the main shaft 1, that is, the main shaft 1 is fixed on the horizontal plane through the base 6.

[0080] The upper end surface of the base 6 has a plurality of accommodating grooves 61 which are arranged around the main shaft 1 at intervals and correspond to the plurality of groups of strips 3 one by one, and the plurality of cylinder bodies 5 are inserted into the plurality of accommodating grooves 61 one by one.

[0081] Each of the accommodating grooves 61 has a reserved hole 62 on the inner wall thereof; when the cylinder body 5 is inserted into the accommodating groove 61 and the base 51 abuts against the groove bottom of the accommodating 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.

[0082] In some embodiments, as shown in FIGS. 1, 3, 4, 5, 8, 10 and 11, each of the cylinder body 5 and the base 6 has a discharge pipe 7; one end of the discharge pipe 7 communicates with the discharge port 511, and the other end extends through the reserved hole 62 to extend outwards, so as to direct the discharge of the medium and avoid the outflow of the medium in the gap between the cylinder body 5 and the base 6, thereby avoiding the waste of the medium (and the heat or cold carried by the medium).

[0083] It should be noted that the part of the discharge port 511 in the cylinder body 5 adopts a conical structure, and the small-diameter end of the conical structure is below the large-diameter end; similarly, the part of the discharge pipe 7 communicating with the discharge port 511 adopts a funnel-shaped structure to adapt to the conical structure and ensure the output rate of the medium.

[0084] Specifically, as shown in FIGS. 8 and 10, the discharge port 511 adopts a circular truncated cone structure extending in the up-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 extends along the radial direction of the cylinder body 5 and penetrates the cylinder body 5.

[0085] Moreover, the connecting end of the discharge pipe 7 and the discharge port 511 is connected with a funnel-shaped connecting piece 71; after the discharge pipe 7 is inserted into the discharge port 511 and extends outwards, 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 medium in the discharge port 511 can enter the discharge pipe 7 through the connecting piece 71, and the movement of the discharge pipe 7 outwards of the discharge port 511 is limited.

[0086] In some embodiments, as shown in FIGS. 8-10, each strip 3 adopts a tubular structure with an internal hollow and open at both ends.

[0087] The aforementioned piston 41 further has a plurality of second through holes 412 penetrating in the up-down direction and corresponding to the plurality of strips 3; it is to be noted that the second through holes 412 are also communicated with the aforementioned feed port 421, so as to guide the injected medium into the interior of the strip 3.

[0088] The upper side of the base 51 has a plurality of third through holes 512 communicated with the discharge port 511 and corresponding to the plurality of strips 3, and a fourth through hole 513 communicated with the discharge port 511 and the interior of the cylinder 5. In the present embodiment, the base 51 comprises an internally hollow seat body with an opening upward, and a top cover detachably connected to the opening end of the seat body and provided with the third through holes 512 and the fourth through hole 513; wherein the opening of the seat body can pass the aforementioned connecting piece 71. The purpose of such design is to facilitate the adjustment and replacement of the discharge pipe 7 when the seat body and the top cover are separated.

[0089] That is to say, the discharge port 511 is a cavity passing through the interior of the base 51 to the peripheral wall of the base 51; based on this, the base 51 is communicated with the interior of the cylinder 5 through the fourth through hole 513, so as to realize the discharge of the medium in the cylinder 5 (not in the strip 3).

[0090] It is to be noted that the main structure of each strip 3 can adopt one of a straight line shape, a spiral shape, and a multi-joint bending shape; in the present embodiment, the strip 3 adopts a straight line shape, so as to facilitate the loading during production and installation; when the structure of the strip 3 adopts a non-straight line shape, the occupancy of the strip 3 in the cylinder 5 is increased, so as to ensure the heat exchange effect when the medium passes through the cylinder 5 and the strip 3.

[0091] In some embodiments, as shown in FIGS. 6 and 7, the interior of the cylinder 5 has a plurality of stabilizers 8 arranged in the up-down direction at intervals; each stabilizer 8 is connected with the cylinder 5 and has a plurality of positioning holes 81 adapted for the corresponding plurality of strips 3 to pass through one by one.

[0092] By adopting the above technical solution, each stabilizer 8 can support each strip 3 correspondingly, so as to avoid the irregular buckling of the strip 3; that is to say, when the strip 3 is in an unloaded state, the part of the strip 3 on the upper side of the stabilizer 8 at the upper end, between the adjacent two stabilizers 8, and on the lower side of the stabilizer 8 at the lower end, all buckles in the horizontal direction, so as to regularize the area of the strip 3 that elastically deforms, and make the corresponding heat exchange phenomenon arrangement area more uniform.

[0093] In some embodiments, as shown in FIGS. 1-5, the upper end surface of the transmission seat 42 is provided with a plurality of rolling balls 422; the rolling ball 422 abuts against the lower surface of the rotating disc 2, and the rolling ball 422 is adapted to roll relative to the transmission seat 42 to optimize the transition of the transmission seat 42 between the rotating disc 2 and the protruding portion 22, thereby reducing noise and irregular vibration.

[0094] In some embodiments, as shown in FIG. 4, the rotating driving member 21 is a rotating motor fixedly arranged at the upper end of the main shaft 1; in this embodiment, the upper end surface of the main shaft 1 is provided with a groove 11, and the rotating driving member 21 is a rotating motor fixedly arranged in the groove 11; the power output shaft of the rotating motor is parallel to the vertical direction, and the power output end thereof is connected with the rotating disc 2 to achieve effective driving of the rotating disc 2 and the rotating connection relationship between the rotating disc 2 and the main shaft 1. Of course, in other embodiments, the rotating driving member 21 can also be a component including a motor, a gear transmission structure or a belt structure, which is not limited in particular.

[0095] In some embodiments, as shown in FIGS. 1-3, the number of groups of the strips 3 is an even number, and a plurality of groups of the strips 3 are arranged at equal intervals around the main shaft 1; in this embodiment, for example, the strips 3 have six groups, and the six groups of strips 3 can be evenly divided into three types of strips 3 that are symmetric to each other according to symmetry along the main shaft 1, and of course, the number can also be other numbers, such as four groups, eight groups, ten groups, etc.

[0096] There are a plurality of driving arms 9 between the two groups of strips 3 that are axially symmetric around the main shaft 1; each driving arm 9 is rotationally connected with 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 the left and right ends thereof are respectively hingedly connected with 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, in addition, the left and right ends of the driving arm 9 refer to the two ends in the length direction of the driving arm 9).

[0097] In addition, the number of protruding portions 22 is half of the number of groups of strips 3; when there are a plurality of protruding portions 22, the plurality of protruding portions 22 are distributed at equal intervals in the circumferential direction of the rotating disc 2. In this embodiment, for example, the protruding portions 22 have three, and the three protruding portions 22 can simultaneously abut against the three lifting members 4; at the same time, the remaining three lifting members 4 abut against the lower surface of the rotating disc 2.

[0098] That is, when one group of strips 3 is in an unloaded state, the other group of strips 3 that is axially symmetric to it around the main shaft 1 is in a loaded state.

[0099] By adopting the technical scheme, in the process of switching the strip 3 from the loaded state to the unloaded state, the strip 3 can generate the unloading work, and the unloading work can act on the driving arm 9 and be transmitted to another group of strips 3 which are axially symmetrical to the main shaft 1, so that the unloading work of the elastic deformation of the elastic material to the original state can be effectively utilized to improve the energy efficiency ratio of the solid elastic card refrigeration and heating device.

[0100] Of course, in other embodiments, the number of groups of strips 3 can also be odd, for example, in addition to the above-mentioned several groups of strips 3 which are arranged in axial symmetry and configured with driving arms 9, several groups of independent strips 3 can also be additionally configured according to the difference in the demand for heat and cold, at this time, the number of protrusions 22 needs to be correspondingly adjusted to meet the demand for collecting more heat or cold.

[0101] Based on the solid elastic card refrigeration and heating device proposed in any of the foregoing, the embodiment of the present application further provides a solid elastic card refrigeration and heating method, comprising the following steps:

[0102] A. Rotate the driving member 21 to rotate the rotating disc 2 by a preset angle, so that at least one protrusion 22 abuts against the lifting piece 4, thereby switching at least one group of strips 3 from the unloaded state to the loaded state;

[0103] B. In a preset time, collect the heat released by the several groups of strips 3 in the loaded state, and the cold generated by the several groups of strips in the unloaded state (that is, the heat absorbed by the several groups of strips 3 in the unloaded state);

[0104] C. Repeat steps A and B.

[0105] After steps A to C, a large amount of heat and cold is obtained in the system, and the heat or cold generated by each group of strips 3 is respectively guided out and used for heating or cooling; when space cooling is needed, the heat absorption of the medium by the cold can be used to reduce the temperature of the input medium and discharge the medium towards the inside of the space; when space heating is needed, the heat exchange between the medium and the heat can be used to increase the temperature of the input medium and discharge the medium towards the inside of the space, so as to finally increase the temperature of the space.

[0106] The solid elastic card refrigeration and heating method provided by the embodiment of the present application has the same beneficial effects as the solid elastic card refrigeration and heating device described above, and will not be described here.

[0107] The above is only a preferred embodiment of the present application, and does not limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
