Description

Technical Field

[0001] This invention relates to a novel solid-state refrigeration and heating technology, specifically a zoned solid-state combined cooling and heating system driven by a tension-torsion synergy. Background Technology

[0002] Elastothermic materials are the most suitable solid-state thermal effect materials in solid-state refrigeration systems and are considered the most suitable alternative to gas compression refrigeration. When elastothermal materials are stretched or contracted, an adiabatic temperature change occurs; stretching releases heat, while contraction absorbs heat. Torsional refrigeration is a novel elastothermal refrigeration technology. When the material is twisted or de-twisted, an adiabatic temperature change occurs; twisting releases heat, while de-twisting absorbs heat. Torsional refrigeration can achieve a Carnot efficiency of up to 65%, far exceeding the efficiency of elastothermal refrigeration (approximately 31%) and compression refrigeration (approximately 60%). Achieving cogeneration through the combination of different stages of material processing provides a feasible and efficient way to reduce refrigeration / heating energy consumption.

[0003] However, most existing elasto-thermal or torsional-thermal refrigeration systems can only perform single stretching / contraction or torsion / de-torsion operations. Compared to stretching + torsion and contraction + de-torsion, the heat / cold output is lower. Some devices require multiple motors to perform both stretching and torsion operations on multiple materials. When controlled by a single motor, since there is only one power shaft output, the power shaft must either perform a stretching action or a torsion action. Due to the limited number of power shafts, these two functions cannot be performed simultaneously. If they are simply assembled together, a state of alternating cold zone-hot zone-cold zone will occur. The heat / cold output of the previous stage cannot be completely dissipated, affecting the heat / cold output of the next stage. In addition, it increases the input power consumption and reduces the system efficiency.

[0004] Furthermore, existing devices are prone to heat loss due to mixing during the transition between hot and cold zones. Additionally, airflow cannot always flow along the length of the material to completely remove heat / cold energy, thus reducing cooling efficiency. Even if some devices have insulation layers to separate hot and cold zones, the alternation between cold and hot zones means that if the cooling generated in the previous stage is not completely removed, heat will mix in the next stage, reducing cooling capacity.

[0005] To address this issue, the present invention employs a power unit that enables simultaneous stretching and torsion, as well as contraction and de-torsion, effectively inducing entropy change and generating more heat and cold energy from the material. Simultaneously, it establishes distinct hot and cold zones to reduce the mixing of heat and cold energy and to promptly remove heat / cold energy, achieving combined heat and cold generation and improving system efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a zoned solid-state combined cooling and heating system with a tension-torsion synergistic drive. Through the coordinated operation of a motor, a universal torque-increasing drill bit, a slider, and a slide rail, it achieves simultaneous tension + torque and contraction + de-torsion functions, effectively inducing entropy change. This allows the material to absorb more heat during cooling and release more heat during heating, significantly improving cooling / heating efficiency. Simultaneously, by setting up hot and cold zones and an insulation layer, the mixing loss of heat and cold is reduced, and variable-direction air vents ensure that airflow always follows the length of the material, guaranteeing timely and effective removal of heat and cold.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A zoned solid-state combined cooling and heating system with tension and torsion synergistic drive, the system comprising a shell, a power shaft, a transmission shaft, a large power gear, a transmission gear, a small power gear, a slider, a slide rail, a heat insulation layer, a flexible shaft, a universal torsion drill bit, and tension and torsion materials;

[0009] The upper part of the inner shell is a hot zone, and the lower part is a cold zone. The hot and cold zones are separated by a heat insulation layer.

[0010] Through holes for slide rails and sliders to enter and exit are provided at both ends of the insulation layer, and a channel 14 for tension and torsion materials to enter and exit is provided in the middle of the insulation layer.

[0011] The power pinion 5 has no internal meshing teeth, but external meshing teeth occupy half of its circumference. The power gear 3 is equipped with both internal and external meshing teeth, with the external meshing teeth covering the entire circumference of the power gear and the internal meshing teeth occupying half of its circumference, complementing the external meshing teeth of the power pinion 5. The transmission gear 4 is covered with external meshing teeth, which can mesh with the internal meshing teeth of the power gear 3 or the external meshing teeth of the power pinion 5. The power gear 3 and the power pinion 5 are coaxially mounted on the power shaft 1. The rotation of the power shaft 1 drives the power gear 3 and the power pinion 5 to rotate simultaneously. They share the same power shaft, which is driven by a motor.

[0012] The transmission gear 4 is mounted on the transmission shaft 2. One end of the transmission shaft 2 is connected to the universal torque drill bit 12 via a flexible shaft. The universal torque drill bit is located outside the power gear and inside the eccentric position of the heat insulation layer.

[0013] A guide component is provided on the inner wall of the outer casing to limit the movement trajectory of the slide rail. The slide rail moves within the track defined by the guide component. The side of the slide rail 9 facing the power gear is covered with internal teeth. The internal teeth of the slide rail 9 mesh with the external teeth of the power gear 3. The movement of the slide rail is driven by the meshing of the external teeth of the power gear and the internal teeth of the slide rail. A slider 6 is fixed on the side of the slide rail. The slider can follow the movement of the slide rail and does not interfere with the guide component during the movement of the slider.

[0014] The tension-torsion material is fixed between the universal torque drill bit and the slider;

[0015] An upper air outlet 7 is installed at the top of the hot zone, and a lower air outlet 8 is installed at the bottom of the cold zone;

[0016] An air inlet channel 16 is provided on the flexible shaft located at the eccentric part of the insulation layer. The air inlet channel is connected to the inside of the universal torque drill bit. The air outlet duct 15 is coaxially installed on the universal torque drill bit with the tension and torsion material. The air outlet duct is connected to the air inlet channel.

[0017] Furthermore, the guiding component is a structure of multiple sets of guide wheels or an elliptical guide rail arranged in a dispersed manner.

[0018] Furthermore, the flexible shaft is connected to the universal torque drill bit 12, and the connection point between the two is located at the eccentric shaft of the heat insulation layer. An air inlet channel 16 is provided on the flexible shaft at the connection point.

[0019] Furthermore, the motor drives the power shaft to rotate counterclockwise. When the transmission gear meshes with the small power gear, it drives the transmission shaft to rotate clockwise. The flexible shaft connected to the transmission shaft drives the universal torque drill bit to apply torque to the tensile material, while the slider is in the hot zone. When the transmission gear meshes with the large power gear, it drives the transmission shaft to rotate counterclockwise. The flexible shaft connected to the transmission shaft drives the universal torque drill bit to de-twist the tensile material, while the slider is in the cold zone.

[0020] Furthermore, the outer shell is elliptical cylindrical in shape, and its longitudinal cross-section is elliptical. The heat insulation layer is located at the major axis of the ellipse. The cold and hot zones divide the interior of the outer shell into two parts along the major axis of the ellipse, and the two zones are symmetrically arranged.

[0021] Furthermore, the original length of the tension-torsion material is the shortest distance from the universal torque drill bit to the insulation layer, which is approximately 1 / 4 to 1 / 2 of the length of the major semi-axis of the ellipse; the tension-torsion material at its maximum elongation is not less than the longest distance from the universal torque drill bit to the insulation layer.

[0022] Furthermore, the outer shell is wrapped with heat-insulating material; the inner gear of the power gear, the outer gear of the power pinion 5, and the outer gear of the transmission gear 4 are located on the same rotation plane, and the outer gear of the power gear and the inner gear of the slide rail are located on the same rotation plane.

[0023] Furthermore, the large power gear and the small power gear are coaxially fixed on the power shaft. One end of the large power gear is provided with a groove, and the groove is the mounting plane for the small power gear and the transmission gear. An internal gear is provided on the side wall of the groove of the large power gear, which meshes with the external gear of the transmission gear 4.

[0024] Furthermore, the insulation layer is filled with a high-efficiency insulation material, which is at least one of asbestos, rock wool, or silicate.

[0025] The tension-torsion material is made of multiple strands of monofilament tightly twisted together, and uses at least one of rubber fiber, nickel-titanium alloy wire, polytetrafluoroethylene (PVDF), polyethylene or nylon.

[0026] Furthermore, the system includes a control unit. The power gear and motor are installed in the hot zone. The control unit is electrically connected to the motor. The control unit controls the slider to move smoothly along the slide rail. Initially, the slider is located closest to the universal torque drill bit, and the tension material is in its original length. The slide rail rotates clockwise. In the hot zone, as the slider moves along the slide rail, it moves further and further away from the universal torque drill bit 12, causing the tension material to stretch. In the cold zone, the slider moves the tension material along the slide rail towards the universal torque drill bit, causing the tension material to contract.

[0027] When the slider 6 moves from the hot zone to the insulation layer, the movement speed of the slider is reduced by changing the speed of the motor, thereby reducing the disturbance to the airflow; when the tension and torsion material 13 approaches the insulation layer 10 in the cold zone, the contraction and de-torsion slow down, and the wind speed and air volume of the blowing duct 15 are reduced, thereby reducing the disturbance to the airflow and reducing the mixing loss of heat and cold.

[0028] When the tension-torsion material 13 moves to its original length, it enters the hot zone from the cold zone through the tension-torsion material channel, returns to the initial state, and repeats the cycle.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1) This invention achieves simultaneous stretching and torque application, as well as contraction and de-torsion application, to materials using a single motor via a gear combination. The motor provides power to the device, rotating the power shaft and driving a large power gear and a small power gear, both sharing the same power shaft. The small power gear has no internal teeth, while its external teeth occupy half of its circumference. Conversely, the large power gear is equipped with both internal and external teeth, with the external teeth covering the entire circumference and the internal teeth occupying half of the circumference, complementing the external teeth of the small gear. The transmission gears are covered with external teeth, enabling them to mesh with either the large or small power gear, achieving alternating meshing of the teeth of the three gears driven by one power shaft, thus alternating between clockwise and counterclockwise rotation of the transmission shaft. The transmission shaft controls the clockwise and counterclockwise rotation of the universal torque-applying drill bit via a connected flexible shaft, achieving torque application and de-torsion of the material. The power shaft drives the large and small power gears to rotate. When the motor drives the power shaft to rotate counterclockwise, the transmission gear meshes with the small power gear, causing the transmission shaft to rotate clockwise. The flexible shaft connected to the transmission shaft drives the universal torque drill bit to apply torque to the material. Conversely, when the transmission gear meshes with the large power gear, it drives the transmission shaft to rotate counterclockwise, and the flexible shaft connected to the transmission shaft drives the universal torque drill bit to release the torque from the material. Furthermore, the external teeth of the large power gear mesh with the internal gear of the slide rail, driving the movement of the slide rail. The slider, located on the side of the slide rail, moves with the slide rail, stretching the material in the hot zone and contracting it in the cold zone. The entire system, through the coordinated operation of three gears and one slide rail, achieves the dual functions of simultaneously stretching and torturing, as well as contracting and releasing the material using a single power source.

[0031] 2) In this invention, a motor drives a power shaft, which in turn drives a gear mechanism. A transmission shaft connects to a universal torque-applying drill bit via a flexible shaft, causing a slide rail to move a slider. Simultaneously, the torque-applying drill bit applies and releases torque. Through the alternating meshing of the transmission gear with the large and small power gears, the material simultaneously undergoes stretching and torque application, releasing heat to the environment (heat generation), creating a hot zone. Conversely, when the material simultaneously contracts and releases torque, it absorbs heat from the environment (cooling), creating a cold zone. This operation, through the material's contraction and torque application, generates more heat and cold, forming distinct hot and cold zones, facilitating heat management and preventing potential heat loss during transitions between hot and cold zones.

[0032] 3) In this invention, by connecting a flexible shaft to the drive shaft, and the flexible shaft connecting to the universal torque drill bit, the universal torque drill bit can be driven to rotate 360 ​​degrees. An air inlet duct is set on the side of the heat insulation layer, and an air outlet duct is set on the universal torque drill bit. The direction of the air outlet duct moves with the rotation of the universal torque drill bit, so that the air outlet direction of the universal torque drill bit is always consistent with the length direction of the tension and twisting material. The airflow always flows out along the length direction of the material, which can transfer the cold / heat of the material to the airflow in a timely manner through convection. The cold / heat is discharged at the lower / upper air outlet, improving the system efficiency.

[0033] 4) A heat insulation layer is installed between the hot and cold zones to separate them, avoiding potential heat loss due to mixing during the alternation of hot and cold zones. The hot zone is located above the heat insulation layer, and the cold zone is located below it. A channel for tension / torsion material is set in the middle of the heat insulation layer to ensure the smooth passage of the material. When the slider moves from the hot zone to the heat insulation layer, the movement speed of the slider is reduced by changing the motor speed, thereby reducing airflow disturbance and minimizing heat loss caused by heat mixing. Due to the rising of hot air and the sinking of cold air, the heat in the hot zone accumulates at the top, and the cold air in the cold zone accumulates at the bottom. The heat insulation layer effectively separates the hot and cold zones, reducing heat loss caused by heat mixing.

[0034] 5) The motor and gears of this invention are located in the hot zone. The motor can release heat in the hot zone and use airflow to expel the heat. The power shaft drives the three gears to mesh alternately, thereby realizing the alternating clockwise and counterclockwise rotation of the transmission shaft. The transmission shaft is connected to a flexible shaft, which is connected to a universal torque drill bit. The universal torque drill bit is fixed to the eccentric shaft of the heat insulation layer. The clamping end of the universal torque drill bit can rotate 360 ​​degrees, thereby causing the clamped tension material to rotate. The distance between the clamping end of the universal torque drill bit and the leftmost end is about 1 / 4 to 1 / 2 of the length of the long semi-axis of the ellipse. Its specific position can be adjusted according to the length of the tension material.

[0035] 6) This invention utilizes a slider fixed to the side of a slide rail to move a tension / torsion material along the rail, thereby achieving the stretching and contraction process of the material. Both ends of the tension / torsion material are connected to a universal torque drill bit and the slider, ensuring that the material can achieve stretching + torsion and contraction + de-torsion functions during movement. The number of strands, diameter, and degree of torsion of the tension / torsion material can be adjusted according to actual needs to flexibly control the output of heat and cold, meeting the heat and cold requirements in different environments.

[0036] 7) This invention achieves stretching + torsion and contraction + de-torsion functions with a single motor. The upper zone is always a hot zone regardless of the stage, and the lower zone is always a cold zone regardless of the stage. This solves the problem of heat / cold mixing caused by the incomplete removal of heat / cold from the previous stage when the hot and cold zones alternate at different stages. The air outlet duct moves with the universal torsion drill bit, ensuring that the air outlet direction is always consistent with the length direction of the stretched and torsioned material. The airflow always flows along the material, increasing the convective heat transfer coefficient and ensuring that heat and cold can be removed in a timely and effective manner, significantly improving system efficiency.

Detailed Implementation

[0042] The present invention will be further explained below with reference to the embodiments and accompanying drawings, but this is not intended to limit the scope of protection of this application.

[0043] The present invention relates to a zoned solid-state combined cooling and heating system driven by tension and torsion, the main components of which are: 1. a power shaft; 2. a transmission shaft; 3. a large power gear; 4. a transmission gear; 5. a small power gear; 6. a slider; 9. a slide rail; 10. a heat insulation layer; 11. a flexible shaft; 12. a universal torsion drill bit; 13. tension and torsion material; 14. a tension and torsion material channel; 15. an air outlet duct; 16. an air inlet duct; and an outer shell. The entire system is equipped with a fully covered outer shell (not shown in the figure). The outer shell is elliptical cylindrical in shape, similar to the shape of a water tank on a sprinkler truck or a fish can. Its longitudinal cross-section is elliptical. A guide component is installed on the inner wall of the outer shell to restrict the movement trajectory of the sliding rail. The sliding rail moves within the track defined by the guide component and is not fixed to the inner wall of the outer shell, allowing it to rotate along the elliptical track within the shell. The upper area inside the outer shell is a hot zone, and the lower area is a cold zone. The hot and cold zones are separated by a heat insulation layer. Utilizing the stratification of hot and cold airflow densities, the mixing of hot and cold air during alternating hot and cold periods is reduced. The heat insulation layer divides the interior of the outer shell into cold and hot zones, with the overall cross-section of both zones being elliptical. The heat insulation layer is located at the major axis of the ellipse. The cold and hot zones divide the interior of the outer shell into two symmetrical sections along the major axis of the ellipse. An upper air outlet 7 is located at the top of the hot zone, and a lower air outlet 8 is located at the bottom of the cold zone.

[0044] In addition, the outer shell is wrapped with thermal insulation material to reduce heat loss from the external environment. The shell encloses both cold and hot areas to ensure structural integrity and airtightness.

[0045] The flexible shaft 11 and the universal torque drill bit 12 are in the same plane. The function of the flexible shaft is to connect the drive shaft at one end and the universal torque drill bit at the other end.

[0046] Through holes are provided at both ends of the insulation layer for the slide rail and slider to enter and exit, and a channel 14 is provided in the middle of the insulation layer for the tension and torsion material to enter and exit, so that the tension and torsion material can smoothly pass through the channel as it moves with the slide rail and slider. Figure 3 Positions A, B, and C represent three different locations of the slider during its movement.

[0047] like Figure 1This system achieves simultaneous stretching and torsion, as well as contraction and de-torsion, of materials through a gear combination. A motor provides power to the system. The power pinion 5 has no internal teeth but external teeth, occupying half of its circumference. The power gear 3 is equipped with both internal and external teeth; the external teeth cover the entire circumference of the power gear, while the internal teeth occupy half of its circumference, complementing the external teeth of the power pinion 5. The transmission gear 4 is covered with external teeth, which can mesh with either the internal teeth of the power gear 3 or the external teeth of the power pinion 5. The power gear 3 and power pinion 5 are coaxially mounted on a power shaft 1. Rotation of the power shaft 1 drives both the power gear 3 and power pinion 5 to rotate simultaneously, sharing the same power shaft.

[0048] The transmission gear 4 is mounted on the transmission shaft 2. One end of the transmission shaft 2 is connected to the universal torque drill bit 12 via a flexible shaft. The universal torque drill bit is located outside the power gear and inside the heat insulation layer.

[0049] The inner side of the slide rail 9 (i.e., the side facing the power gear) is covered with internal teeth. These internal teeth mesh with the external teeth of the power gear 3. The movement of the slide rail is driven by the meshing of the external teeth of the power gear with the internal teeth of the slide rail. A slider 6 is fixed to the side of the slide rail. The slider moves with the slide rail without interfering with the guide assembly. The guide assembly can be a structure of multiple dispersed guide wheels, or an elliptical guide rail, etc. The power gear provides the moving power to the slide rail, ensuring that the slide rail maintains its position during movement. Figure 2 The elliptical cross-sectional shape is shown.

[0050] The drive shaft 2 controls the clockwise and counterclockwise rotation of the torque-applying drill bit 12 via a connected flexible shaft, realizing the application and release of torque on the tensile and torsional material. The power shaft 1 drives the large power gear 3 and the small power gear 5 to rotate. The motor drives the power shaft to rotate counterclockwise. When the drive gear 4 meshes with the small power gear 5, it drives the drive shaft 2 to rotate clockwise. The flexible shaft 11 connected to the drive shaft 2 drives the universal torque-applying drill bit 12 to apply torque to the tensile and torsional material. Conversely, when the drive gear 4 meshes with the large power gear 3, it drives the drive shaft 2 to rotate counterclockwise. The flexible shaft connected to the drive shaft 2 drives the universal torque-applying drill bit 12 to release the tensile and torsional material 13. During this process, the external teeth of the large power gear 3 are always meshed with the internal gear of the slide rail, driving the slide rail to move. The internal gear of the power gear, the external gear of the power pinion 5, and the external gear of the transmission gear 4 are located on the same plane of rotation. The external gear of the power gear and the internal gear of the slide rail are located on the same plane of rotation. A slider 6 is fixed on the side of the slide rail. The slider does not interfere with the power gear, power pinion, transmission gear, flexible shaft, etc. during the movement of the slide rail.

[0051] The slider 6 is located on the outer side of the slide rail 9. As the slide rail moves, it can stretch the material in the hot zone and shrink it in the cold zone. The entire system achieves the dual functions of simultaneously stretching and twisting the material and shrinking and untwisting it through the coordinated operation of three gears and one slide rail.

[0052] The large power gear and the small power gear are coaxially fixed on the power shaft. A groove is provided at one end of the large power gear, and the groove is the mounting plane of the small power gear and the transmission gear. An internal gear is provided on the side wall of the groove of the large power gear, which meshes with the external gear of the transmission gear 4.

[0053] like Figure 4 The insulation layer is filled with high-efficiency insulation materials, including but not limited to asbestos, rock wool, and silicates, effectively isolating the heat exchange between the hot and cold zones. The insulation layer between the hot and cold zones achieves thermal separation, preventing potential heat loss during mixing. The hot zone is located above the insulation layer, and the cold zone is located below it. A channel 14 for the passage of the tension / torsion material is provided in the middle of the insulation layer to ensure its smooth passage. When the slider 6 moves from the hot zone to the insulation layer, the motor speed is changed to reduce the slider's movement speed, thereby reducing airflow disturbance and minimizing heat loss caused by heat mixing. Due to the rising of hot air and the sinking of cold air, heat from the hot zone accumulates at the top, and cold air from the cold zone accumulates at the bottom. The insulation layer effectively separates the heat and cold zones, reducing heat loss during mixing.

[0054] In this invention, the tension-torsion material is made by tightly twisting multiple monofilaments. A wide range of these monofilament tension-torsion materials can be selected, including rubber fibers, nickel-titanium alloy wires, polytetrafluoroethylene (PVDF), polyethylene, nylon, and other materials. The original length of the tension-torsion material is the shortest distance from the universal torque drill bit to the insulation layer, approximately 1 / 4 to 1 / 2 of the length of the major semi-axis of the ellipse. To meet the needs of different refrigeration applications, multiple parameters of the tension-torsion material can be flexibly adjusted, such as diameter, number of strands, length, number of twisting turns, twisting speed, stretching speed, and shrinkage speed. At its maximum elongation, the tension-torsion material is not less than the longest distance from the universal torque drill bit to the insulation layer.

[0055] In this invention, one end of the tension / torsion material is fixed to the universal torque drill bit 12, while the other end is connected to the slider via a special hanger or clamp. This prevents the tension / torsion material from falling off during high-speed movement or under excessive tension, allowing this end to move along the slide rail along a predetermined path. The slider 6 and slide rail 9 are typically made of high-strength, low-friction materials, such as stainless steel and aluminum alloy, and undergo coating, lubrication or grease treatment, polishing, etc., to improve surface finish, reduce roughness and frictional resistance of the contact surfaces, ensure that the slider can run smoothly along the predetermined path, reduce the probability of derailment, and reduce wasted energy consumption, thereby improving the durability and reliability of the system.

[0056] The moving speed of slider 6 and the torque-applying speed of universal torque-applying drill 12 are regulated by the motor connected to the power shaft 1. The system of this invention also includes a control unit. When the slider moves from the hot zone to the insulation layer, the output speed of the motor is reduced, thereby reducing the moving speed of the slider, the torque-applying speed of the universal torque-applying drill, and the airflow speed. This reduces the loss of heat and cold due to airflow disturbance, ensuring that the slider can follow the track at a predetermined speed and that the universal torque-applying drill applies torque at a predetermined speed. The control unit controls the slider to move smoothly along the slide rail. Initially, the slider is located at the position closest to the universal torque-applying drill, and the tension-twisting material is in its original length. The slide rail rotates clockwise. In the hot zone, as the slider moves along the slide rail with the tension-twisting material connected to it, it moves further and further away from the universal torque-applying drill 12, causing the tension-twisting material to stretch. In the cold zone, the slider moves the tension-twisting material gradually closer to the universal torque-applying drill along the slide rail, causing the tension-twisting material to contract. Simultaneously, the tension-twisting material is torqued in the hot zone and de-torsed in the cold zone. This allows for simultaneous stretching and twisting in the hot zone, and simultaneous contraction and de-twisting in the cold zone. For example: Figure 2 When the slider moves from position A to the insulation layer, the tension-torsion material is stretched and twisted, reaching its maximum length. When the tension-torsion material moves from the insulation layer to position B, it contracts and untwists. When the tension-torsion material moves from position B to position C, it continues to contract and untwist. This allows the system to achieve stretching + torsion and contraction + untwist using a single motor, and it also has distinct cold and hot zones, reducing cooling loss during transitions and improving refrigeration efficiency.

[0057] like Figure 4In this invention, the large power gear and motor are installed in the hot zone. The motor provides the power source for the system, driving the power shaft 1. Through the alternating meshing of the small power gear and the transmission gear 4, the transmission shaft 2 is driven to move. The transmission shaft 2 is connected to a flexible shaft 11, which is connected to a universal torque-adjusting drill bit 12. The connection point between the two is located at the eccentric shaft of the insulation layer. An air inlet duct 16 is provided on the flexible shaft at the connection point, communicating with the interior of the universal torque-adjusting drill bit. The universal torque-adjusting drill bit clamps a tension / torsion material at its center. An air outlet duct 15 is provided on the outside of the universal torque-adjusting drill bit, communicating with the air inlet duct. The flexible shaft drives the universal torque-adjusting drill bit to rotate 360 ​​degrees, causing the tension / torsion material to be torqued or de-torsioned. The air outlet duct and the tension / torsion material are on the same straight line, enabling flexible clockwise and counterclockwise rotation of the tension / torsion material. The air inlet duct 16 passes through the side of the insulation layer, that is, a hole is drilled in the front and back direction of the insulation layer to allow air to enter. The air flows out through the air outlet duct. The air outlet duct is wrapped around the universal torque drill bit 12 and moves with the rotation of the universal torque drill bit 12, so that the direction of the air outlet duct is consistent with the length direction of the tension and twist material. The airflow flows along the length direction of the tension and twist material, which can promptly carry the cold / heat of the tension and twist material out from the air outlet and improve the cooling / heating efficiency.

[0058] The working process of tension-torsion materials is divided into two stages, as follows (e.g.) Figure 2 ):

[0059] In the first stage, the motor provides power to the device, driving the power shaft (1) to rotate counterclockwise. When the power shaft drives the large power gear (3) and the small power gear (5) to rotate, the small power gear (5) meshes with the transmission small gear (4), driving the transmission shaft (2) to rotate clockwise, which in turn drives the universal torque drill bit (12) connected to the flexible shaft (11) to rotate clockwise, thus applying torque to the tension-torsion material (13). At the same time, the large power gear (3) drives the slide rail (9) to move, and the slider (6) located on the side of the slide rail (9) stretches the tension-torsion material (13), and the tension-torsion material releases heat to the environment (heating). The airflow enters from the air inlet pipe (16) and flows out from the air outlet pipe (15). The airflow moves together with the universal torque drill bit (12) and conducts convective heat exchange with the tension-torsion material (13), and the heat generated during the stretching and torque process is discharged in time through the upper air outlet (7). When the tension-torsion material is stretched to its maximum length, the tension-torsion material (13) approaches the insulation layer (10) from the top. By changing the speed of the motor and the power of the fan, the stretching and torsion speed is slowed down and the air velocity and air volume of the air outlet duct (15) are reduced, thus reducing the disturbance of the airflow.

[0060] In the second stage, when the tension-torsion material (13) passes through the channel (14) inside the insulation layer, the transmission gear (4) begins to mesh with the power gear (3), driving the transmission shaft (2) to move counterclockwise, thereby driving the universal torque drill bit (12) connected to the flexible shaft (11) to rotate counterclockwise, thus de-torsing the tension-torsion material; at the same time, the tension-torsion material fixed to the slider (6) begins to contract, and the tension-torsion material absorbs heat (cools) from the environment. The airflow enters from the air inlet pipe (16) and flows out from the air outlet pipe (15), moving together with the universal torque drill bit (12), and convectively exchanging heat with the tension-torsion material (13), so that the cold energy generated during its contraction and de-torsion process is discharged in time at the lower air outlet (8). When the tension-torsion material (13) approaches the insulation layer (10) in the cold zone, the contraction and detorsion speeds slow down and the air velocity and air volume of the air outlet duct (15) are reduced, thus reducing airflow disturbance. Until the tension-torsion material (13) moves to its original length, the tension-torsion material continues to enter the hot zone from the cold zone through the tension-torsion material channel from the other side of the insulation layer, repeating the process of the first and second stages. The above stages are repeatedly cycled to stably and continuously discharge cold and heat.

[0061] Any aspects not covered in this invention are applicable to existing technologies.
