Description

Technical Field

[0001] The invention belongs to the field of refrigeration equipment, and in particular relates to a twist-card refrigeration and heating device with both cold and hot end separation and work recovery functions. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, the demand for energy-saving and environmentally friendly refrigeration technology is growing. Traditional vapor compression refrigeration technology has gradually exposed many problems due to its high energy consumption and adverse effects on the environment, and card refrigeration has gradually emerged as a cutting-edge technology with great potential. Card refrigeration uses shape memory materials such as NiTi alloy as the core. Through the stress-induced deformation and reverse deformation process, it uses the thermal effect of the material during loading and unloading to achieve heating and cooling. Its cyclic deformation process does not rely on greenhouse gas refrigerants at all, and its environmental performance is excellent. Compared with traditional refrigeration methods, card refrigeration has significant advantages in low noise, high energy efficiency and simple structure, especially showing great potential in reducing carbon emissions and improving energy efficiency.

[0003] In recent years, the research on spring-cage cooling prototypes has made significant progress. Various prototype forms represented by stretched shape memory alloy wire, compressed shape memory alloy thin-walled tube and bent shape memory alloy ribbon have been developed. There are relatively few research reports on prototypes based on torsion loading (i.e., twist-cage cooling prototypes). However, from the analysis of the experimental results of twist-cage cooling samples in the existing literature, twist-cage cooling technology shows many advantages, including small driving force requirements, long material fatigue life and high specific cooling power (SCP) per unit mass. These characteristics provide important directions and possibilities for the further development of spring-cage cooling technology. Although the existing prototypes have made great progress in key performance indicators such as temperature span, cooling power and energy efficiency ratio, their overall performance still does not fully meet the needs of practical applications and marketization.

[0004] The existing eject card prototypes mainly have the following technical problems:

[0005] On the one hand, from the perspective of heat exchange efficiency, the existing spring-cage refrigeration prototypes perform cooling and heating at the same location during the cooling and heating process due to the limitations of the internal structure design, and fail to effectively separate the cold and hot areas. As a result, when increasing the power by speeding up the operating frequency, it is limited by the inherent cycle of the material, and the cold and hot air flows mix and interfere with each other, which greatly reduces the heat exchange efficiency, greatly restricts the overall cooling power, and cannot meet the needs of modern society for fast and precise temperature control.

[0006] On the other hand, in terms of energy utilization, the operating mechanisms of these prototypes are often not optimized. On the one hand, there is a phenomenon of power waste during unloading in existing prototypes, that is, there is no power recovery during the unloading process; on the other hand, when performing the task of loading and unloading refrigerant, the power source rotation direction is frequently changed, resulting in a large amount of unnecessary power loss, just like the frequent emergency braking and starting of a vehicle while driving, which consumes fuel for no reason. The energy utilization rate is at a low level. These limitations run counter to the current trend of energy conservation and emission reduction.

[0007] Furthermore, most existing refrigeration devices use a single heat exchange medium, which will face technical difficulties such as sealing and cannot achieve ideal hot and cold separation. At the same time, the single function has also become a major shortcoming of existing spring card refrigeration prototypes. Most of them only focus on the simple refrigeration function, and it is difficult to meet the dual needs of users for hot water and cold air at the same time, which seems to be stretched in actual life and production application scenarios.

[0008] The above technical difficulties limit the further improvement of the performance indicators of the spring card refrigeration prototype and hinder its application and marketization. Therefore, further developing a spring card refrigeration prototype with better performance, especially the innovative design combined with twist card refrigeration technology, is an important research direction to promote the industrialization of this technology.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] (1) The present invention uses a loading and unloading device composed of a stator module composed of an external gear and an internal gear and a rotor module composed of a twisted refrigerant and a loading gear to achieve cooling and heating. During operation, the loading gear acts as a moving gear and has orbital and self-rotation. When it orbits, it drives the twisted refrigerant to change the heat exchange position, and when it rotates, it drives the twisted refrigerant to load and unload. Both the internal gear and the external gear adopt an incomplete gear design (that is, both are only provided with teeth on part of the edge). When the loading gear is meshed with the teeth of the internal gear, the loading gear rotates in the forward direction, thereby realizing the loading operation of the twisted refrigerant; and when the loading gear is meshed with the teeth of the external gear, the loading gear reverses to complete the unloading process of the twisted refrigerant. The device has multiple significant advantages: first, with the help of the unique structure of the incomplete gear set, the loading area and the unloading area are cleverly separated, which is equivalent to separating the cooling area from the heating area. It not only effectively avoids the problem of mutual interference between cold and heat affecting the heat exchange efficiency, but also breaks through the limitation of operating frequency on power, that is, the operating frequency can be accelerated to pursue greater power; second, during the operation of the loading gear carrying the torsion card refrigerant, it only needs to maintain the same orbital direction to successfully complete the two tasks of loading and unloading, without frequently changing the rotation direction, thereby reducing unnecessary power loss; what is particularly critical is that during the coordinated transmission of the loading gear and the incomplete gear set, the energy released when the torsion card refrigerant in the unloading area is unloaded can be transmitted to the loading area, providing auxiliary power for the loading process, successfully realizing the recovery and reuse of power, and greatly improving the overall energy utilization efficiency.

[0027] (2) The present invention can be used to exchange heat for both gas and liquid at the same time. In the loading area, that is, the heating area, liquid is used as the heat exchange medium; and in the unloading area, that is, the cooling area, gas is used for heat exchange. Such a unique heat exchange design contains many advantages: on the one hand, liquid has a higher specific heat capacity, which can significantly enhance the heat exchange effect; on the other hand, gas heat exchange has relatively low requirements for sealing, thereby reducing the sealing requirements. The two complement each other, cleverly resolving the dilemma of power limitation when the existing prototype exchanges heat at the same position, and effectively achieving the goal of separating hot and cold; on the other hand, the heating area can fully meet the user's needs for heating liquids, and the cooling area can supply cold air in a timely manner, realizing dual-purpose use of one machine, bringing great convenience to users.

[0037] Reference Figures 1 to 3 , showing a twist card refrigeration and heating device with both cold and hot end separation and work recovery functions provided by this embodiment, including a stator module 1, a rotor module 2, a rotating power source and a heat exchange module 3.

[0038] Reference Figure 4The stator module 1 includes an outer gear 11 and an inner gear 12. The outer gear 11 is an annular structure with an inner ring. The inner gear 12 is located in the inner ring of the outer gear 11, and an annular gap 13 is provided between the outer periphery of the inner gear 12 and the inner periphery of the outer gear 11. It is particularly important that both the outer gear 11 and the inner gear 12 are designed as incomplete gears, that is, the outer gear 11 is provided with first teeth 111 on a portion of the edge of its inner ring, and the outer edge of the inner gear 12 is provided with second teeth 121 at a position offset from the first teeth 111.

[0039] Reference Figure 5 and Figure 6 The rotor module 2 includes a rotating frame 21, a twisted refrigerant 22, a loading gear 23, a first sealing ring 24 and a second sealing ring 25. The rotating frame 21 includes a first end plate 211, a second end plate 212 and a rigid rod 213. The two ends of the rigid rod 213 are fixedly connected to the first end plate 211 and the second end plate 212, respectively, so that the rotating frame 21 has a certain structural strength. One end of the twisted refrigerant 22 is fixedly connected to the first end plate 211, and the other end is fixedly connected to the loading gear 23. The loading gear 23 is rotatably mounted on the second end plate 212. Through this structural design, only the axial linear displacement of the twisted refrigerant 22 is limited, but it is free to rotate. The first end plate 211 is transmission-connected to the rotating power source. In this embodiment, a motor is used as the rotating power source. When the motor is working, it can drive the entire rotor module 2 to rotate.

[0040] The loading gear 23 is located in the annular gap 13. By controlling the rotation direction of the rotor module 2, the inner gear 12 corresponds to the loading area and the outer gear 11 corresponds to the unloading area. When the loading gear 23 is meshed with the inner gear 12 in the stator module 1, the twisted refrigerant 22 is loaded to form a heat generating area; when the loading gear 23 is meshed with the outer gear 11, the twisted refrigerant 22 is unloaded to form a cooling area, which separates the heating and cooling areas.

[0041] Reference Figure 2 and Figure 3 The heat exchange module 3 includes an inner cylinder 31 and an outer cylinder 32. The inner cylinder 31 is located inside the outer cylinder 32. An annular chamber 33 is formed between the outer periphery of the inner cylinder 31 and the inner wall of the outer cylinder 32. The twisted card refrigerant 22 is located inside the annular chamber 33. The gap between one port of the annular chamber 33 and one end of the twisted card refrigerant 22 is sealed by a first sealing ring 24, and the gap between the other port of the annular chamber 33 and the other end of the twisted card refrigerant 22 is sealed by a second sealing ring 25.

[0042] Reference Figure 7The outer tube 32 is provided with a gas inlet 321, a gas outlet 322, a liquid inlet 323 and a liquid outlet 324, wherein the gas inlet 321, the upper space of the annular chamber 33 and the gas outlet 322 together constitute a gas heat exchange flow channel. The liquid inlet 323, the lower space of the annular chamber 33 and the liquid outlet 324 together constitute a liquid heat exchange flow channel.

[0043] The lower space of the annular chamber 33 matches the loading area and serves as a heating area for heating the liquid; the upper space of the annular chamber 33 matches the unloading area and serves as a cooling area for cooling the gas. The top surface of the liquid in the heating area forms a closed environment with the cooling area, which plays the role of sealing the cooling area.

[0044] Furthermore, the twist card cooling and heating device of this embodiment also includes an air pump and a liquid pump. When working, the air pump transports gas from the gas inlet 321 into the cooling area, and the gas flows out from the gas outlet 322 after being cooled in the cooling area; the liquid pump transports liquid from the liquid inlet 323 into the heating area, and the liquid flows out from the liquid outlet 324 after being heated in the heating area.

[0045] Further, refer to Figure 1 and Figure 3 , the twist card cooling and heating device of this embodiment also includes a first fixed support 4, a transmission shaft 5, a second fixed support 6 and an end cover 7. The transmission shaft 5 is mounted on the first fixed support 4 through a bearing 8, one end of the transmission shaft 5 is transmission-connected to the rotary power source, and the other end is fixedly connected to the first end plate 211. In this embodiment, the end cover 7 is fixed on the second fixed support 6, and a mounting shaft 71 extends from the inner side of the end cover 7, and the second end plate 212 is rotatably mounted on the mounting shaft 71. When the rotary power source is working, it can drive the transmission shaft 5 to rotate, thereby driving the entire rotor module 2 to rotate, while the stator module 1, the heat exchange module 3, the first fixed support 4, the second fixed support 6 and the end cover 7 remain stationary.

[0046] Specifically, the first sealing ring 24 is fixed on the inner side of the first end plate 211 and covers one end of the annular chamber 33. One end of the twisted refrigerant 22 passes through the first sealing ring 24 and is fixedly connected to the inner side of the first end plate 211. The second sealing ring 25 covers the other end of the annular chamber 33. The annular chamber 33, the first sealing ring 24 and the second sealing ring 25 together constitute a sealed heat exchange space. Figure 5 and Figure 6As shown, a sealing plug 26 is fixed to the other end of the twisted refrigerant 22, and the sealing plug 26 is rotatably sealed and embedded in the second sealing ring 25 and is in close contact with the second sealing ring 25; the loading gear 23 is coaxially connected to the sealing plug 26. Through the above structural design, the twisted refrigerant 22 will not affect the sealing performance of the heat exchange space during the torsional deformation process.

[0047] like Figure 6 As shown, a gear installation shaft 2121 extends from the inner side surface of the second end plate 212 , and the loading gear 23 is rotatably sleeved on the gear installation shaft 2121 , so that the loading gear 23 can rotate around the gear installation shaft 2121 .

[0048] In this embodiment, the rotor module 2 includes multiple torsion refrigerants 22 and multiple loading gears 23, the number of torsion refrigerants 22 is the same as the number of loading gears 23, wherein the multiple torsion refrigerants 22 are distributed at intervals along the circumferential direction of the annular chamber 33, and the multiple loading gears 23 are distributed at intervals along the circumferential direction of the annular gap 13.

[0049] Preferably, each twist-lock refrigerant 22 of this embodiment is formed by twisting a plurality of spring-lock material wires, and the material of the spring-lock material wires is a shape memory alloy material. The first end plate 211 and the second end plate 212 are both circular plates, and the inner cylinder 31 and the outer cylinder 32 are both cylinders.

[0050] In summary, the twist card refrigeration and heating device provided in this embodiment has at least the following beneficial effects:

[0051] 1. The present invention adopts a loading and unloading device composed of a stator module 1 composed of an outer gear 11 and an inner gear 12 and a rotor module 2 composed of a twisted refrigerant 22 and a loading gear 23 to achieve cooling and heating. During operation, the loading gear 23, as a moving gear, has revolution and rotation. The revolution drives the twisted refrigerant 22 to change the heat exchange position, and the rotation drives the twisted refrigerant 22 to load and unload. Both the outer gear 11 and the inner gear 12 adopt an incomplete gear design (that is, both are only provided with teeth on part of the edge). When the loading gear 23 is meshed with the teeth of the inner gear 12, the loading gear 23 rotates in the forward direction, thereby realizing the loading operation of the twisted refrigerant 22; and when the loading gear 23 is meshed with the teeth of the outer gear 11, the loading gear 23 reverses to complete the unloading process of the twisted refrigerant 22. The device has multiple significant advantages: first, with the help of the unique structure of the incomplete gear set, the loading area and the unloading area are cleverly separated, which is equivalent to separating the cooling area from the heating area, effectively avoiding the problem of mutual interference between cold and heat, and greatly improving the heat exchange efficiency; second, during the operation, the loading gear 23 carrying the twisted refrigerant 22 only needs to maintain the same orbital direction to successfully complete the two tasks of loading and unloading, without frequently changing the rotation direction, thereby reducing unnecessary power loss; what is particularly critical is that during the period of coordinated transmission between the loading gear 23 and the incomplete gear set, the rebound force of the twisted refrigerant 22 in the unloading area during unloading is transmitted to the loading area, and can be transmitted to the loading area, providing auxiliary power for the loading process, successfully realizing the recovery and reuse of power, and greatly improving the overall energy utilization efficiency.

[0052] 2. The heat exchange fluid uses an innovative mode of combining gas and liquid. The heat exchange gas can be air, nitrogen, etc., and the heat exchange liquid can be water, silicone oil and other heat exchange media with good thermal conductivity. Figure 6 As shown, this embodiment takes the combination of air and water as an example. In the loading area, that is, the heating area, water is used as the heat exchange medium; and in the unloading area, that is, the cooling area, air is used for heat exchange. Such a unique heat exchange design contains many advantages: on the one hand, liquid has a higher specific heat capacity, and heat exchange with water can significantly enhance the heat exchange effect. Air heat exchange has relatively low requirements for sealing. The two complement each other and cleverly resolve the power limitation of the existing prototype when exchanging heat at the same position, and effectively achieve the goal of hot and cold separation; on the other hand, the heating area can fully meet the user's daily demand for hot water and perfectly serve as a water heater. The cooling area can supply cold air in time, effectively exerting the cooling effect of the air conditioner, truly realizing the dual use of one machine, bringing great convenience to users.
