Description

Technical Field

[0001] The present invention relates to a novel solid refrigeration and heating technical field, in particular to a zoned solid cooling and heating cogeneration system driven by tension and torsion synergy. Background Art

[0002] Elastic caloric refrigeration materials are the most suitable solid thermal effect materials in solid refrigeration systems and are considered to be the most suitable alternative technology to gas compression refrigeration. When elastomeric caloric materials are stretched or contracted, an adiabatic temperature change will occur, releasing heat when stretched and absorbing heat when contracted. Among them, torsional caloric refrigeration is a new type of elastomeric caloric refrigeration technology. When the material is twisted or untwisted, an adiabatic temperature change will occur, releasing heat when twisted and absorbing heat when untwisted. The Carnot efficiency of torsional refrigeration can reach up to 65%, which is much higher than the efficiencies of elastomeric refrigeration (about 31%) and compression refrigeration (about 60%). The cogeneration of cold and heat is achieved through the combination of materials at different stages, providing a feasible and efficient way to reduce refrigeration / heat energy consumption.

[0003] However, most of the existing elastic-caloric or torsional-caloric refrigeration systems can only perform a single stretching / contraction or twisting / untwisting operation. Compared with stretching + twisting and contraction + untwisting, the heat / cold amount generated is lower. Some devices need to use multiple motors to perform both stretching and twisting operations on multiple materials. When a single motor is controlled, since there is only one power shaft output, the power shaft either performs a stretching action or a twisting action. Due to the limited power shaft, these two functions cannot be performed at the same time. If they are simply assembled together by force, a state of alternating cold zone-hot zone-cold zone will appear. The cold / heat amount in the previous stage cannot be completely discharged, affecting the cold / heat amount in the next stage. In addition, the input power consumption is increased, which reduces the system efficiency.

[0004] Furthermore, in the process of switching between hot and cold zones, existing devices are prone to mixing and loss of cold and heat, and the airflow cannot always flow along the length of the material to completely remove the cold and heat, thereby reducing the cooling efficiency. Even if some devices have an insulation layer to separate the hot and cold zones, for the upper and lower zones, the cold zone-hot zone-cold zone alternates. If the cold generated in the previous stage is not completely removed, it will cause the heat in the next stage to mix, thereby reducing the cold.

[0005] To solve this problem, the present invention adopts a set of power devices to realize the working modes of simultaneous stretching + twisting and contraction + untwisting, which can effectively induce entropy change and make the material generate more heat and cold. At the same time, obvious hot and cold partitions are set to reduce the mixing of cold and heat, and discharge cold / heat in time to realize the system's combined production of cold and heat and improve system efficiency. Summary of the invention

[0006] The purpose of the present invention is to provide a zoned solid heat and cold cogeneration system driven by tension and torsion synergistically. Through the cooperation of the motor, the universal torsion drill, the slider and the slide rail, the functions of simultaneous stretching + torsion and contraction + untwisting are realized, effectively inducing entropy change, so that the material absorbs more heat during the refrigeration process and releases more heat during the heating process, significantly improving the refrigeration / heat efficiency. At the same time, by setting up hot and cold zones and insulation layers, the mixing loss of cold and heat is reduced, and variable direction air outlets are set up so that the airflow always flows along the length direction of the material, ensuring that the cold and heat can be discharged in a timely and effective manner.

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

[0015] An upper air outlet 7 is provided at the top of the hot zone, and a lower air outlet 8 is provided 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 heat insulation layer, and the air inlet channel is connected to the inside of the universal torsion drill bit. An air outlet duct 15 is coaxially installed on the universal torsion drill bit with the torsion material, and the air outlet duct is connected to the air inlet channel.

[0017] Furthermore, the guide assembly is a plurality of guide wheel structures or elliptical guide rails that are dispersedly arranged.

[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 axis of the heat insulation layer. An air inlet channel 16 is provided on the flexible shaft at the connection point.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1) The present invention realizes the functions of simultaneous stretching + twisting and contraction + untwisting of materials by a single motor through a gear combination. The motor provides power for the device, and the power shaft rotates, driving the large power gear and the small power gear to operate, and the two share the power shaft. There is no meshing tooth inside the small power gear, and the external meshing tooth occupies half of its circumference. Relatively speaking, the large power gear is equipped with both internal and external meshing teeth, of which the external meshing tooth covers the entire circumference of the gear, while the internal meshing tooth occupies half of the circumference, which complements the external meshing tooth of the pinion gear. The outside of the transmission gear is covered with external meshing teeth, so that it can mesh with the large power gear or the small power gear, so that one power shaft drives the meshing teeth of three gears to mesh alternately, thereby realizing the clockwise and counterclockwise rotation of the transmission shaft alternately. The transmission shaft controls the clockwise and counterclockwise rotation of the universal torque drill through the connected flexible shaft, thereby realizing the twisting and untwisting of the material. The power shaft drives the large power gear and the small power gear to rotate. When 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, and the flexible shaft connected to the transmission shaft drives the universal twisting drill to twist the material; and 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 twisting drill to untwist the material. In addition, the outer teeth of the large power gear mesh with the inner gear of the slide rail to drive the movement of the slide rail. The slider is located on the side of the slide rail. With the movement of the slide rail, it can drive the torsion material to stretch in the hot zone and shrink in the cold zone. The entire system realizes the dual functions of simultaneously stretching + twisting and shrinking + untwisting the material using a single power source through the coordinated cooperation of three gears and one slide rail.

[0031] 2) In the present invention, the power shaft is driven by a motor, and the power shaft drives the gear mechanism to move. The transmission shaft is connected to the universal twist drill through a flexible shaft, so that the slide rail drives the slider to move, and the twist drill performs twisting and untwisting at the same time. Through the alternating meshing of the transmission gear with the large power gear and the small power gear, when the material is stretched + twisted at the same time, it releases heat to the environment (heating), and the area at this time is the hot zone; when the material is contracted + untwisted at the same time, it absorbs heat from the environment (cooling), thereby cooling, and the area at this time is the cold zone. This operation absorbs / releases heat through the contraction + untwisting and stretching + twisting of the material, which can generate more cold and heat, and form obvious hot and cold zones, which is conducive to the management of cold and heat, and avoids the loss of cold and heat that may be generated when the hot and cold zones are replaced.

[0032] 3) In the present invention, a flexible shaft is connected to the transmission shaft, and the flexible shaft is connected to the universal twist drill bit, which can drive the universal twist drill bit to rotate 360 ​​degrees. An air inlet duct is arranged on the side of the insulation layer, and an air outlet duct is arranged on the universal twist drill bit. The direction of the air outlet duct moves with the rotation of the universal twist drill bit, so that the air outlet direction of the universal twist drill bit is always consistent with the length direction of the tension and twist material, and the airflow always flows out along the length direction of the material. The cold / heat of the material can be transferred to the airflow in time through convection, and the cold / heat can be discharged at the lower / upper air outlet, thereby improving the system efficiency.

[0033] 4) An insulation layer is set between the hot and cold zones to separate the hot and cold zones and avoid the mixing loss of cold and heat that may occur when the hot and cold zones alternate. The hot zone is above the insulation layer, and the cold zone is below the insulation layer. A torsion material channel is set in the middle of the insulation layer to ensure the smooth passage of the torsion material. When the slider moves from the hot zone to the insulation layer, the speed of the motor is changed to reduce the movement speed of the slider, thereby reducing the disturbance of the airflow and reducing the heat loss caused by the mixing of cold and heat. Due to the buoyancy of hot air and the sinking of cold air, the heat in the hot zone accumulates at the top, and the cold in the cold zone accumulates at the bottom. The insulation layer is used to effectively separate the cold and heat, reducing the heat loss caused by the mixing of cold and heat.

[0034] 5) The motor and gears of the present invention are arranged in the hot zone. The heat dissipation of the motor can be released in the hot zone, and the heat is discharged by airflow. The power shaft drives the meshing teeth of the three gears to engage alternately, thereby realizing the alternating clockwise and counterclockwise rotation of the transmission shaft. The transmission shaft is connected to the flexible shaft, and the flexible shaft is connected to the universal torque drill bit. The universal torque drill bit is fixed on the eccentric shaft of the thermal insulation layer. The clamping end of the universal torque drill bit can rotate 360 ​​degrees, thereby rotating the clamped tensile and torsion material. The distance between the clamping end of the universal torque drill bit and the leftmost end is approximately 1 / 4-1 / 2 of the length of the major semi-axis of the ellipse, and its specific position can be adjusted according to the length of the tensile and torsion material.

[0035] 6) The present invention drives the torsion material to move along the slide rail by setting a slider fixed on the side of the slide rail, thereby realizing the stretching and contraction process of the material. The two ends of the torsion material are respectively connected to the universal torsion drill and the slider to ensure that the material can achieve the functions of stretching + torsion and contraction + untwisting during the movement. The number of strands, diameter and degree of torsion of the torsion material can be adjusted according to actual needs to flexibly control the output of cold and heat to meet the cold and heat requirements in different environments.

[0036] 7) The present invention realizes the functions of stretching + twisting, contraction + untwisting through a single motor. The upper zone is a hot zone at any stage, that is, the upper zone is always a hot zone, and the lower zone is a cold zone at any stage, that is, the lower zone is always a cold zone. This solves the problem of heat / cold mixing caused by the cold / heat of the previous stage not being completely discharged when the hot and cold zones alternate at different stages. The air outlet duct moves with the universal twisting drill bit, so that the air outlet direction is always consistent with the length direction of the stretched and twisted material, and the airflow always flows along the material, which increases the convective heat transfer coefficient, ensures that the cold and heat can be discharged in a timely and effective manner, and significantly improves the system efficiency.

The hot and cold areas are separated by an insulation layer, and the characteristics of the density stratification of the hot and cold air flows are utilized to reduce the hot and cold mixing generated when the hot and cold air alternate; the insulation layer divides the inside of the shell into a cold area and a hot area, and the overall cross-section of the cold and hot areas is an ellipse. The insulation layer is located at the long axis position of the ellipse, and the cold and hot areas divide the inside of the shell into two along the long axis of the ellipse, and the two areas are symmetrically arranged. An upper air outlet 7 is provided at the top of the hot area, and a lower air outlet 8 is provided at the bottom of the cold area.

[0044] In addition, the outer shell is wrapped with insulation material to reduce heat exchange losses with the external environment. The outer shell wraps the cold area and the hot area inside to ensure the integrity and sealing of the structure.

[0045] The flexible shaft 11 and the universal torsion drill 12 are in the same plane, and the flexible shaft has the following functions: one end is connected to the transmission shaft, and the other end is connected to the universal torsion drill.

[0046] Through holes for the slide rails and sliders to enter and exit are provided at both ends of the heat insulation layer, and a channel 14 for the pull-twist material to enter and exit is provided in the middle of the heat insulation layer, so that the pull-twist material can smoothly pass through the channel while following the movement of the slide rails and sliders. Figure 3 The three positions A, B, and C are three different positions of the slider during its movement.

[0047] like Figure 1, the system realizes the simultaneous stretching + twisting and contraction + untwisting functions of the material through a gear combination. The motor provides power for the system. The power pinion 5 has no internal teeth, but is provided with external teeth on the outside, and the external teeth occupy half of the circumference of the power pinion 5; the power large gear 3 is equipped with both internal and external teeth, wherein the external teeth cover the entire circumference of the power large gear, while the internal teeth occupy half of the circumference of the power large gear, which complements the external teeth of the power pinion 5; the outside of the transmission gear 4 is covered with external teeth, and the external teeth of the transmission gear 4 can mesh with the internal teeth of the power large gear 3 or with the external teeth of the power pinion 5. The power large gear 3 and the power pinion 5 are coaxially mounted on the power shaft 1, and the rotation of the power shaft 1 drives the power large gear 3 and the power pinion 5 to operate simultaneously, and the two share the power shaft.

[0048] The transmission gear 4 is installed on the transmission shaft 2. One end of the transmission shaft 2 is connected to a universal torsion drill 12 through a flexible shaft. The universal torsion drill is located outside the large power gear and inside the heat insulation layer.

[0049] The inner side of the slide rail 9 (i.e., the side facing the large power gear) is covered with internal teeth, and the internal teeth of the slide rail 9 mesh with the external teeth of the large power gear 3, and the meshing of the external teeth of the large power gear with the internal gear of the slide rail drives the slide rail to move. A slider 6 is fixed to the side of the slide rail, and the slider can move with the slide rail, and does not interfere with the guide assembly during the movement of the slider. The guide assembly can be a structure of multiple sets of guide wheels arranged in a dispersed manner, or it can be an elliptical guide rail, etc. The large power gear provides the moving power of the slide rail, so that the slide rail always maintains the movement process. Figure 2 The oval cross-sectional shape shown.

[0050] The transmission shaft 2 controls the clockwise and counterclockwise rotation of the twist drill 12 through the connected flexible shaft to achieve twisting and untwisting of the torsion material. The power shaft 1 drives the power gear 3 and the power pinion 5 to rotate, and the motor drives the power shaft to rotate counterclockwise. When the transmission gear 4 is meshed with the power pinion 5, it drives the transmission shaft 2 to rotate clockwise, and the flexible shaft 11 connected to the transmission shaft 2 drives the universal twist drill 12 to twist the torsion material; and when the transmission gear 4 is meshed with the power gear 3, it drives the transmission shaft 2 to rotate counterclockwise, and the flexible shaft connected to the transmission shaft 2 drives the universal twist drill 12 to untwist the torsion material 13. In this process, the outer teeth of the power gear 3 are always meshed with the inner gear of the slide rail, driving the slide rail to move. The inner gear of the large power gear, the outer gear of the small power gear 5, and the outer gear of the transmission gear 4 are located in the same rotation plane. The outer gear of the large power gear and the inner gear of the slide rail are located in the same rotation plane. A slider 6 is fixed on the side of the slide rail. The slider follows the movement of the slide rail without interfering with the large power gear, the small power gear, the transmission gear, the flexible shaft, etc.

[0051] The slider 6 is located on the outer side of the slide rail 9. With the movement of the slide rail, it can drive the torsion material to stretch in the hot zone and shrink in the cold zone. The whole system realizes the dual functions of stretching + twisting and shrinking + untwisting the material at the same time by a single power source through the coordinated cooperation of three gears and a slide rail.

[0052] The power gear is coaxially fixed on the power shaft with the power pinion. A groove is provided at one end of the power gear. The groove is the mounting plane for the power pinion and the transmission gear. An internal gear is provided on the side wall of the groove of the power gear to mesh with the external gear of the transmission gear 4.

[0053] like Figure 4 , the interior of the thermal insulation layer is filled with high-efficiency thermal insulation materials, which include but are not limited to asbestos, rock wool and silicate, etc., which effectively isolate the heat exchange between the hot zone and the cold zone. An insulation layer is set between the cold and hot zones to achieve the separation of hot and cold, and avoid the loss of cold and heat that may be generated when the hot and cold zones are mixed. The hot zone is above the insulation layer, and the cold zone is below the insulation layer. A channel 14 for the entry and exit of the torsion material is set in the middle of the insulation layer to ensure the smooth passage of the torsion material. When the slider 6 moves from the hot zone to the insulation layer, the speed of the motor is changed to reduce the movement speed of the slider, thereby reducing the disturbance of the airflow and reducing the heat and cold loss caused by the mixing of cold and heat. Due to the floating of hot air and the sinking of cold air, the heat in the hot zone accumulates at the top, and the cold in the cold zone accumulates at the bottom. The insulation layer is used to effectively separate the cold and heat, reducing the mixing loss of cold and heat.

[0054] In the present invention, the torsion material is formed by tightly twisting multiple strands of monofilaments. The selection range of these monofilament torsion materials is wide, covering a variety of materials such as rubber fiber, nickel-titanium alloy wire, polytetrafluoroethylene (PVDF), polyethylene, nylon, etc. The original length of the torsion material is the shortest distance from the universal torsion drill bit to the insulation layer, which is about 1 / 4-1 / 2 of the length of the major semi-axis of the ellipse. In order to meet the needs of different refrigeration applications, multiple parameters of the torsion material can be flexibly adjusted, such as diameter, number of strands, length, number of twisting turns, twisting speed, stretching speed, and contraction speed, etc. The torsion material is not less than the longest distance from the universal torsion drill bit to the insulation layer at the maximum elongation.

[0055] In the present invention, one end of the torsion material is fixed on the universal torsion drill bit 12, and the other end is connected to the slider through a special hanger or clamp to prevent the torsion material from falling off in the case of high-speed movement or excessive tension, so that the end can move along the predetermined path with the slider following the slide rail. The slider 6 and the slide rail 9 are usually made of high-strength, low-friction materials, such as stainless steel and aluminum alloy, and are subjected to coating, lubricating oil or grease, polishing and other operations to improve the surface finish, reduce the roughness and friction resistance of the contact surface, ensure that the slider can run smoothly along the predetermined path, reduce the probability of derailment, and reduce the consumption of useless work, thereby improving the durability and reliability of the system.

[0056] The moving speed of the slider 6 and the twisting speed of the universal twisting drill 12 are adjusted by the motor connected to the power shaft 1. The system of the present invention also includes a control unit. When the slider moves from the hot zone to the insulation layer, the motor output speed is reduced, so that the moving speed of the slider, the twisting speed of the universal twisting drill and the wind speed are reduced, reducing the cold and heat mixing loss caused by air flow disturbance, ensuring that the slider can move along the track at a predetermined speed, and the universal twisting drill is twisted at a predetermined speed. The control unit controls the slider to move smoothly along the slide rail. Initially, the slider is located at the closest position to the universal twisting drill, the torsion material is in the original length state, and the slide rail rotates clockwise. In the hot zone, the slider drives the torsion material connected to it to move along the slide rail, and moves farther and farther away from the universal twisting drill 12, driving the torsion material to perform a stretching operation; in the cold zone, the slider drives the torsion material to gradually approach the universal twisting drill along the slide rail, driving the torsion material to perform a contraction operation. At the same time, the torsion material is twisted in the hot zone and untwisted in the cold zone. It can realize the functions of stretching and twisting in the hot zone and shrinking and untwisting in the cold zone. Figure 2 When the slider moves from position A to the insulation layer, the torsion material is stretched and twisted, and the material reaches its maximum length at this time; when the torsion material moves from the insulation layer to position B, the torsion material contracts and untwistes; when the torsion material moves from position B to position C, the torsion material continues to contract and untwist, so that the system uses a single motor to achieve stretching + twisting and contraction + untwisting, and has obvious cold and hot zones, which reduces the loss of cold during replacement and improves the cooling efficiency.

[0057] like Figure 4In the present invention, the power gear and the motor are installed in the hot zone, the motor provides the power source for the system, the motor drives the power shaft 1, and the transmission shaft 2 is driven to move through the alternating meshing of the power pinion and the transmission gear 4, the transmission shaft 2 is connected to the flexible shaft 11, and the flexible shaft is connected to the universal torsion drill 12, the connection point of the two is located at the eccentric shaft of the thermal insulation layer, and the flexible shaft at the connection point is provided with an air inlet duct 16, the air inlet duct is connected to the inside of the universal torsion drill, the center of the universal torsion drill clamps the torsion material, and an air outlet duct 15 is provided on the outside of the universal torsion drill, and the air outlet duct is connected to the air inlet duct. The flexible shaft drives the universal torsion drill to rotate 360 ​​degrees, drives the torsion material to be twisted or untwisted, and the air outlet duct and the torsion material are on the same straight line, so as to realize the flexible rotation of the torsion material in the clockwise and counterclockwise directions. The air inlet duct 16 passes through the side of the insulation layer, that is, a hole is drilled in the front and rear directions of the insulation layer to allow air to enter, and the air flows out from the air outlet duct. The air outlet duct is wrapped around the universal twist drill bit and moves with the rotation of the universal twist drill bit 12, so that the direction of the air outlet duct is consistent with the length direction of the twisted material. The airflow flows along the length direction of the twisted material, and the cold / heat of the twisted material can be brought out from the air outlet in time, thereby improving the cooling / heating efficiency.

[0058] The working process of the tension-torsion material is divided into two stages, as follows (such as 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 power gear (3) and the power pinion (5) to rotate, the power pinion (5) meshes with the transmission pinion (4), driving the transmission shaft (2) to rotate clockwise, thereby driving the universal torsion drill (12) connected to the flexible shaft (11) to rotate clockwise, thereby torsioning the torsion material (13). At the same time, the 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 torsion material (13), and the torsion material releases heat to the environment (heating). The airflow enters from the air inlet duct (16) and flows out from the air outlet duct (15). The airflow moves with the universal torsion drill (12), performs convection heat exchange with the torsion material (13), and discharges the heat generated during the stretching and torsion process through the upper air outlet (7) in a timely manner. When the torsion material is stretched to its longest length, the torsion material (13) approaches the thermal insulation layer (10) from the top, and by changing the rotation speed of the motor and the power of the fan, the stretching and twisting speeds are slowed down and the wind speed and air volume of the air outlet duct (15) are reduced, thereby reducing the disturbance of the air flow.

[0060] In the second stage, when the torsion material (13) passes through the channel (14) inside the heat insulation layer, the transmission gear (4) begins to mesh with the large power gear (3), driving the transmission shaft (2) to move counterclockwise, thereby driving the universal torsion drill bit (12) connected to the flexible shaft (11) to rotate counterclockwise to untwist the torsion material; at the same time, the torsion material fixed to the slider (6) begins to shrink, and the torsion material absorbs heat (cooling) from the environment. The airflow enters from the air inlet duct (16) and flows out from the air outlet duct (15), moving with the universal torsion drill bit (12), and performs convection heat exchange with the torsion material (13), and the cold generated during the shrinkage + untwisting process is discharged in time at the lower air outlet (8). When the torsion material (13) approaches the thermal insulation layer (10) in the cold zone, the speed of contraction and untwisting slows down and the wind speed and air volume of the air outlet duct (15) are reduced, thereby reducing the disturbance of the air flow. Until the torsion material (13) moves to its original length, the torsion material continues to enter the hot zone from the other side of the thermal insulation layer through the torsion material channel from the cold zone, repeating the process of the first stage and the second stage. The above stages are repeatedly cycled to stably and continuously discharge the cold and heat.

[0061] Any matters not described in the present invention are applicable to the prior art.
