Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tempered glass manufacturing, in particular to a double-tank body tempering furnace. BACKGROUND

[0002] Tempered glass, also known as quenching glass or strengthened glass, is a kind of prestressed glass. It is formed by a layer of compressive stress on the surface of ordinary glass through physical or chemical methods, thereby improving the hardness and strength of the glass. It has excellent performance, high impact strength, and high bending strength. The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass. It also has good thermal stability and can withstand a temperature difference of 3 times that of ordinary glass, i.e. 300℃. It also has safety performance, and when broken, it will form a honeycomb-like blunt small particle that is not easy to hurt people. Tempering furnace is a device for producing tempered glass by physical or chemical methods. Physical treatment is to heat and quench flat glass to form a stress layer without changing the chemical composition of the glass. Chemical treatment is to improve the strength of the glass by changing the chemical composition of the glass surface. The existing tempering furnace has the following working process: Glass is conveyed to the heating furnace by a roller, heated to near the softening point temperature, then enters the flat tempering section, rapidly cooled by high-speed airflow to rapidly cool the glass surface to form compressive stress, and the inside forms tensile stress. Finally, the glass is taken out in the sheet taking section and conveyed to the chemical tempering furnace for preheating, tempering (ion exchange), salt dripping, and slow cooling to exchange alkali ions in the glass with potassium ions in the salt to form a compressive stress layer. In actual operation, the following problems exist: 1. High energy consumption: There are frequent temperature rising and falling operations in the production process, resulting in serious energy waste. The heat source discharged during the cooling cycle of the furnace body is not utilized and directly lost, resulting in redundant energy consumption. 2. Low production efficiency: There is a waiting period in the feeding link. When the previous furnace is in production, the next furnace needs to wait for the completion of the previous furnace before it can receive the material due to the lack of feeding tank support, resulting in interruption of the overall production process, reduction of effective production time, and limitation of production capacity. In view of the above problems, it is urgent to innovate and design on the basis of the original tempering furnace. SUMMARY

[0003] The technical solution of the present application provides a significantly different solution from the prior art to solve the problem of high energy consumption and low production efficiency in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dual-tank tempering furnace, including a mounting frame, with two physical processing furnaces provided on the lower surface of the mounting frame, and a plurality of fins installed between two adjacent physical processing furnaces, the plurality of fins being arranged in two rows, and a driving mechanism installed at one end of each fin, the driving mechanism being able to drive the plurality of fins to rotate sequentially to open the heat exchange channel between the two adjacent physical processing furnaces, and to realize multi-level gradient heat exchange operation in the process; The inner wall of the physical treatment furnace is lined with several heat exchange pipes. A docking mechanism is installed on the side of the physical treatment furnace near the fins. Two chemical treatment furnaces are provided on the upper surface of the mounting frame. An isolation plate is provided between the chemical treatment furnace and the physical treatment furnace.

[0005] Preferably, the drive mechanism includes two annular gear tracks distributed one-to-one with the two physical processing furnaces, and a double-layer clamping plate that slides along the annular gear tracks. The inner cavity of the double-layer clamping plate is equipped with a drive gear that meshes with the annular gear tracks, and the inner wall of the annular gear tracks is fixedly connected with a plurality of horizontal plates for connecting fins.

[0006] Preferably, the double-layer clamping plate is divided into an outer clamping plate and an inner clamping plate. A servo motor and a temperature sensor are installed on the outer surface of the outer clamping plate. A controller is electrically connected between the servo motor and the temperature sensor. The output shaft of the servo motor is connected to the drive gear through a shaft. The outer clamping plate and the ring gear track are connected by a sliding connection.

[0007] Preferably, one end of the fin is fixedly connected to a rotating shaft, one end of the rotating shaft is rotatably connected to a horizontal plate, the front half of the rotating shaft is fixedly connected to a rhomboid block, and the rear half of the rotating shaft is wound with a torsion spring.

[0008] Preferably, a protrusion is fixedly connected to the surface of the rhomboid block, one end of the torsion spring abuts against the inner wall of the protrusion, and the other end of the torsion spring is fixedly connected to the inner wall of the horizontal plate.

[0009] Preferably, the inner clamping plate and the rhombus block are located on the same vertical plane. The drive gear is rotated by a servo motor, which further drives the double clamping plate to slide along the ring gear track, so that the inner clamping plate slides against the side wall of the rhombus block, and the fins rotate one by one.

[0010] Preferably, the docking mechanism includes a main pipe laid on one side of the bottom of the physical treatment furnace, and several secondary pipes inserted into the upper surface of the main pipe; Each of the secondary pipes has several sealing bolts slidably connected to its side curved surface. One end of each sealing bolt is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably connected to the surface of the fin.

[0011] Preferably, the first half of the heat exchange pipe is set as a horizontal section, and the second half of the heat exchange pipe is set as a vertical section. The horizontal sections of the heat exchange pipe are all located on the same horizontal plane, and the vertical sections of the heat exchange pipe extend upwards in a stepped manner.

[0012] Compared with the prior art, the beneficial effects of the present invention are: By adding two sets of fins between two adjacent physical processing furnaces and cooperating with the drive mechanism, multi-level gradient heat exchange can be achieved. The drive mechanism can control the fins to rotate one by one to open the heat exchange channel, and can accurately recover the heat source discharged when the physical processing furnace is cooled down from bottom to top, reducing heat waste, avoiding ineffective energy consumption, effectively solving the problem of high energy consumption of traditional tempering furnaces, reducing energy loss from frequent heating and cooling of the furnace body, improving energy utilization, and reducing the total energy consumption cost in the production process. Furthermore, an intelligent drive mechanism is added, employing a ring gear track, double-layer clamping plates, and meshing transmission with drive gears. Combined with temperature sensors and controllers, it achieves precise control of the fin opening position. Dual temperature sensors trigger in opposite directions: the left side senses cooling and triggers the next layer to open, while the right side senses heating up to the target and triggers the next layer to open, forming a collaborative operation. This achieves gradient heat exchange with one layer replacing the next, solving the problem of mixing hot and cold airflows in traditional heat exchange, improving heat exchange efficiency, ensuring that heat is transferred sequentially and directionally, and that the two circulate heat transfer, realizing energy recovery and reuse through one heat dissipation and the other heat absorption, minimizing heat waste. In addition, when the fins open, the sealing bolts of the docking mechanism are pulled by the connecting rod to divert the hot airflow. Most of the hot airflow passes directly through the heat dissipation fins and slowly diffuses to higher levels, spreading gradually from top to bottom and from right to left. A small portion of the hot airflow is guided through the secondary pipe into the main pipe and then into the bottom heat exchange channel, so that the heat diffuses from bottom to top and from left to right, slowly gathering towards the center, maximizing the utilization rate of the hot airflow.

[0013] Furthermore, the dual physical processing furnace can selectively supply workpieces according to the production needs of the two chemical processing furnaces above, without having to be fixed to a particular chemical processing furnace. Instead, it can flexibly allocate the physically processed workpieces based on the idle status of the chemical processing furnaces and the process temperature requirements, thereby improving the efficiency of the connection between upstream and downstream processes, avoiding the waiting problems caused by a single material supply path, reducing material supply waiting time, eliminating the need for additional waiting for material supply, avoiding furnace idleness, shortening the production cycle, increasing the product output per unit time, and effectively improving the problems of low production efficiency and limited capacity of traditional tempering furnaces.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 9 The present invention provides a technical solution: a dual-tank tempering furnace, including a mounting frame 1, two physical processing furnaces 2 are provided on the lower surface of the mounting frame 1, a number of fins 3 are installed between two adjacent physical processing furnaces 2, and the number of fins 3 are arranged in two rows. A driving mechanism 4 is installed at one end of the fins 3. The driving mechanism 4 can drive the number of fins 3 to rotate sequentially to open the heat exchange channel between the two adjacent physical processing furnaces 2, and realize multi-level gradient heat exchange operation in this process. The inner wall of the physical treatment furnace 2 is covered with several heat exchange pipes 5. A docking mechanism 6 is installed on the side of the physical treatment furnace 2 near the fins 3. Two chemical treatment furnaces 7 are provided on the upper surface of the mounting frame 1. An isolation plate 8 is provided between the chemical treatment furnace 7 and the physical treatment furnace 2.

[0026] By adding two sets of fins 3 between two adjacent physical processing furnaces 2, and cooperating with the drive mechanism 4, multi-level gradient heat exchange is achieved. The drive mechanism 4 can control the fins 3 to rotate one by one to open the heat exchange channel, avoid airflow turbulence during the heat exchange process, and improve heat exchange efficiency. Combined with the heat exchange pipes 5 on the inner wall of the physical processing furnace 2, the heat source discharged when the physical processing furnace 2 is cooled can be accurately recovered layer by layer from bottom to top, reducing heat waste, avoiding ineffective energy consumption, effectively solving the problem of high energy consumption of traditional tempering furnaces, reducing energy loss from frequent heating and cooling of the furnace body, improving energy utilization, and reducing the total energy consumption cost in the production process. The dual physical processing furnace 2 can selectively supply workpieces according to the production needs of the two chemical processing furnaces 7 above. It does not need to be fixed to a particular chemical processing furnace 7. Instead, it can flexibly allocate the physically processed workpieces based on the idle status of the chemical processing furnace 7 and the process temperature requirements. This improves the efficiency of the connection between the upstream and downstream processes, avoids the waiting problem caused by a single material supply path, reduces material supply waiting time, realizes a continuous production process, eliminates the need for additional waiting for material supply, avoids furnace body idleness, shortens the production cycle, increases product output per unit time, and effectively improves the problems of low production efficiency and limited capacity of traditional tempering furnaces.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism 4 includes two annular gear tracks 401 distributed one-to-one with the two physical processing furnaces 2, and a double-layer clamping plate that slides along the annular gear track 401. The inner cavity of the double-layer clamping plate is equipped with a drive gear 402 that meshes with the annular gear track 401. Several horizontal plates 407 for connecting the fins 3 are fixedly connected to the inner wall of the annular gear track 401. It should be noted that the two annular gear tracks 401 correspond one-to-one with the two physical processing furnaces 2. Through the meshing transmission of the drive gear 402 and the annular gear track 401, the double-layer clamping plate is driven to slide along the track, so as to achieve smooth and deviation-free transmission. In addition, several horizontal plates 407 are fixed on the inner wall of the track. These plates 407 correspond one-to-one with several fins 3, precisely controlling the rotation angle and rhythm of each fin 3. When one fin 3 is opened by each of the two rows of fins 3, a new heat exchange channel is formed, and the heat energy between the two physical processing furnaces 2 is converted into each other, significantly improving the energy utilization rate and directly reducing the energy consumption cost in production.

[0028] In this embodiment, as Figure 7and Figure 8 As shown, the double-layer clamping plate consists of an outer clamping plate 403 and an inner clamping plate 404. A servo motor 405 and a temperature sensor 406 are mounted on the outer surface of the outer clamping plate 403. A controller 408 is electrically connected between the servo motor 405 and the temperature sensor 406. The output shaft of the servo motor 405 is connected to the drive gear 402 via a shaft. The outer clamping plate 403 and the ring gear track 401 are connected by a sliding connection. It should be noted that the temperature sensor 406 equipped on the outer surface of the outer clamping plate 403 can sense the hot airflow in real time and transmit the temperature data to the controller 408, which is then used as the trigger condition for starting the servo motor 405. After the servo motor 405 is started, it can drive the drive gear 402 to achieve fixed-point movement. The position of the double clamping plate along the ring gear track 401 can be precisely adjusted according to different temperature requirements. Then, the fins 3 are connected through the horizontal plate 407. When the fins 3 rotate to a horizontal state, airflow can be allowed to pass through. High temperature triggers the fins 3 to rotate and perform heat exchange. When the temperature of the flowing gas begins to drop, it indicates that the hot airflow replacement of this layer is completed, which drives the double clamping plate to move to the next fin 3 and start the hot airflow delivery of the next layer. By utilizing the triggering of temperature sensor 406, the heat exchange intensity is matched in real time with different layers within the physical processing furnace 2, avoiding the transfer of cold air to another physical processing furnace 2, thereby improving the accuracy of heat exchange and energy utilization.

[0029] In this embodiment, as Figure 5 and Figure 7 As shown, one end of the fin 3 is fixedly connected to a rotating shaft 301, one end of the rotating shaft 301 is rotatably connected to the horizontal plate 407, the front half of the rotating shaft 301 is fixedly connected to a rhomboid block 302, and the rear half of the rotating shaft 301 is wound with a torsion spring 303. A protrusion is fixedly connected to the surface of the rhombus block 302. One end of the torsion spring 303 abuts against the inner wall of the protrusion, and the other end of the torsion spring 303 is fixedly connected to the inner wall of the horizontal plate 407.

[0030] The inner clamping plate 404 and the rhombus block 302 are located on the same vertical plane. The servo motor 405 drives the drive gear 402 to rotate, which further drives the double clamping plate to slide along the ring gear track 401, so that the inner clamping plate 404 slides against the side wall of the rhombus block 302, and the fins 3 rotate one by one. It should be noted that the servo motor 405 drives the drive gear 402 and the double-layer clamping plate to move at a fixed point along the ring gear track 401. The inner clamping plate 404 slides against the vertical surface of the rhombus block 302, pushing the fin 3 to rotate around the rotating shaft 301. When the fin 3 rotates to the horizontal state, airflow is allowed to pass through. When the temperature is high, the fin 3 at the corresponding position is triggered to rotate. In addition, such as Figure 4and Figure 6 The double-layered clamps on the two annular gear tracks 401 are designed with an alternating upper and lower distribution, which, combined with the temperature difference between the left and right physical processing furnaces 2, achieves directional heat exchange. The specific process is as follows: When the temperature inside the left physical processing furnace 2 is high and hot air needs to be sent out, while the temperature inside the right physical processing furnace 2 is low and hot air needs to be received, the double-layer clamping plate on the left annular gear track 401 is initially at the bottom, and the double-layer clamping plate on the right annular gear track 401 is initially at the top. After the heat exchange is started, the left fins 3 open layer by layer from bottom to top, and the right fins 3 open layer by layer from top to bottom, ensuring that the hot air flows from the lower left layer to the upper layer and from the upper right layer to the lower layer, achieving "one layer, one exchange", and avoiding the mixing of hot and cold air in the conveying path; In addition, the dual temperature sensors 406 are reverse-triggered to achieve precise, step-by-step heat transfer. The left and right temperature sensors 406 are set with reverse triggering conditions via the controller 408 to form a collaborative operation mechanism. Left temperature sensor 406 (hot gas output end): Real-time sensing of hot gas temperature. When the temperature of the airflow passing through this layer drops, it is determined that the hot gas replacement of this layer is completed. The double-layer clamping plate is immediately driven to move to the next fin 3 to start the hot gas delivery of the next layer. Temperature sensor 406 on the right (hot air receiving end): The triggering condition is the opposite of that on the left. When the temperature of the airflow in this layer rises to the expected value, it indicates that the energy stored in the hot airflow has reached the standard. This triggers the servo motor 405 to drive the double-layer clamping plate to move from top to bottom and open the next layer of fins 3 to receive hot air. In the above manner, the heat exchange operation of the dual physical processing furnace 2 can start to be reversed in the second round, breaking the limitation of heat transfer in one direction. When the first round of operation is completed, the temperature of the physical processing furnace 2 on the right is higher and the temperature of the physical processing furnace 2 on the left is lower. At this time, the two double-layer plates also move synchronously, with the right side becoming the hot gas output end and the left side becoming the receiving end. The two circulate to transfer heat, realizing the energy recovery and reuse of one heat discharge and one heat absorption, and minimizing heat waste. In this embodiment, the dual-sensor reverse collaboration design not only completely solves the problem of mixed cold and hot transport in traditional heat exchange, but also realizes precise step-by-step heat transfer, effectively preventing heat accumulation in the upper layer of the physical treatment furnace 2 on the right side, avoiding excessive temperature difference between the upper and lower parts of the furnace, and greatly improving the accuracy of heat exchange and energy utilization. In addition, the fin 3 is rotatably connected to the horizontal plate 407 via the rotating shaft 301. The rhomboid block 302 in the front half of the rotating shaft 301 and the torsion spring 303 in the rear half form a complete rotation and reset mechanism. When the inner clamping plate 404 slides against the side wall of the rhomboid block 302, it pushes the rhomboid block 302 to drive the rotating shaft 301 to rotate, thereby causing the fin 3 to rotate. Meanwhile, the protrusions on the surface of the rhombus block 302 provide support for the torsion spring 303. When the inner layer clamping plate 404 leaves the rhombus block 302, the torsion spring 303 can drive the rotating shaft 301 to reset, and the fins 3 to reset. Then the heat exchange channel of this layer is closed, which not only ensures that the fins 3 can rotate stably under the push of the clamping plate to open the airflow channel, but also achieves automatic reset through the torsion spring 303, ensuring the continuity of the layered heat exchange process.

[0031] In this embodiment, as Figure 4 and Figure 9 As shown, the docking mechanism 6 includes a main pipe 601 laid on one side of the bottom of the physical treatment furnace 2, and several secondary pipes 602 inserted into the upper surface of the main pipe 601. Among them, each secondary pipe 602 has several sealing bolts 603 slidably connected to the side curved surface. One end of the sealing bolt 603 is rotatably connected to a connecting rod 604, and one end of the connecting rod 604 is rotatably connected to the surface of the fin 3. The first half of the heat exchange pipe 5 is set as a horizontal section, and the second half of the heat exchange pipe 5 is set as a vertical section. The horizontal sections of several heat exchange pipes 5 are all located on the same horizontal plane, and the vertical sections of several heat exchange pipes 5 extend upwards in a stepped manner. It should be noted that the docking mechanism 6 consists of a main pipe 601 laid on one side of the bottom of the physical treatment furnace 2 and several secondary pipes 602 inserted into the upper surface of the main pipe 601. Several sealing columns and sealing bolts 603 are slidably connected to the side curved surface of each secondary pipe 602. One end of the sealing bolt 603 is rotatably connected to the connecting rod 604, and the other end of the connecting rod 604 is rotatably connected to the surface of the fin 3. During the rotation of the fin 3 with the double-layer clamping plate, the connecting rod 604 will be triggered to push and pull, thereby driving the sealing bolt 603 to slide along the side curved surface of the secondary pipe 602. In this embodiment, the rear half of the sealing bolt 603 is a solid structure, and the front half is a hollow structure with an opening. When the fin 3 is rotated to a horizontal position, the hollow structure and opening of the front half of the sealing bolt 603 slide backward into the secondary pipe 602, and the channel between the sealing bolt 603 and the secondary pipe 602 opens. The airflow is smoothly introduced into the secondary pipe 602 and is directionally transported to the other side through the heat exchange channel at the bottom. Hot air is simultaneously transported from both sides to the central area, ensuring uniform heat exchange in the furnace during the heat exchange process. When the fin 3 rotates to the closed state, the solid structure of the rear half of the sealing bolt 603 slides into the secondary pipe 602, sealing the inner cavity of the pipe, completely preventing the loss of heat in this layer, ensuring lossless hot air transport, and further reducing energy waste. The heat exchange pipe 5 is made of metal pipe. The first half is set as a horizontal section, and several horizontal sections are located on the same horizontal plane and embedded in the bottom inner wall of the physical treatment furnace 2. The second half is set as a vertical section and embedded in the inner wall of one side of the physical treatment furnace 2. The metal material and the installation method that fits the furnace wall can directly realize the heating operation of the shell of the physical treatment furnace 2, realize the diffusion of heat from bottom to top, maximize the utilization rate of hot air flow, and reduce the loss of heat to the external environment. In addition, the height of several vertical sections extends upward in a stepped manner, and the gas outlet of each heat exchange pipe 5 is located at a different layer. After the hot air enters the heat exchange pipe 5 through the docking mechanism 6, it will be smoothly transported to the vertical section along the horizontal section, and then discharged layer by layer through the outlet of the corresponding level. This corresponds to the action of the fins 3 opening layer by layer, avoiding the accumulation of hot air and further improving the uniformity of heat exchange.

[0032] Working principle: When using this dual-tank tempering furnace, the material is first put into the two physical processing furnaces 2. The left physical processing furnace 2 is started to heat the glass plate inside. After the set time is reached, the sensor feeds back to the two chemical processing furnaces 7 above. The corresponding furnace is selected to put the product in. The isolation plate 8 opens to realize the transfer of the workpiece. After the transfer is completed, the isolation plate 8 closes to prevent heat loss. When the left physical processing furnace 2 has finished putting the material in, it needs to be cooled down. At this time, the right physical processing furnace 2 needs to be heated up. The heat energy inside the left physical processing furnace 2 needs to be transferred to the right physical processing furnace 2. Start the negative pressure fan on the outside of the physical treatment furnace 2 on the right. The negative pressure fan starts, generating negative pressure and initiating the heat exchange operation. The temperature sensor 406 of the outer layer plate 403 of the left physical processing furnace 2 senses that the temperature of the hot airflow has reached the standard and transmits the data to the controller 408, triggering the servo motor 405 to start. The servo motor 405 drives the drive gear 402 to rotate via the shaft. The drive gear 402 meshes with the ring gear track 401, causing the left double-layer clamping plate to slide from bottom to top along the track, and the right double-layer clamping plate to slide from top to bottom along the track simultaneously. When the double-layer clamping plates slide, the inner clamping plate 404 is in contact with the diamond block 302 on the transverse plate 407 on the inner wall of the ring gear track 401, pushing the diamond block 302 to drive the rotating shaft 301 to rotate, thereby causing the left fin 3 to open from bottom to top and the right fin 3 to open from top to bottom. When the fin 3 rotates to a horizontal state, airflow can be allowed to pass through. At this time, under the action of the negative pressure fan on the right, the hot airflow on the left enters the right side. As the fins 3 open, the connecting rod 604 pulls the sealing bolt 603 of the docking mechanism 6. The hollow structure and opening of the front half of the sealing bolt 603 slide into the secondary pipe 602, and the passage between the secondary pipe 602 and the main pipe 601 opens. The hot airflow of the physical treatment furnace 2 on the left is diverted. Most of the hot airflow passes directly through the heat dissipation fins 3 and slowly diffuses to a high position, gradually spreading from top to bottom and from right to left. A small portion of the hot airflow is guided by the secondary pipe 602, enters the main pipe 601, then enters the bottom heat exchange channel, and then flows into the horizontal section of the heat exchange pipe 5, starting to diffuse from bottom to top and from left to right, slowly gathering towards the center. Next, the left temperature sensor 406 senses that the current layer airflow temperature has dropped, indicating that cold air from the bottom has begun to mix in. It is determined that the hot airflow replacement in this layer is complete. The controller 408 triggers the servo motor 405 again, which moves the left double-layer clamping plate to the next fin 3. The right temperature sensor 406 senses that the current layer airflow temperature has risen to the expected value, which determines that the heat absorption is up to standard. It will also trigger the right double-layer clamping plate to move to the next fin 3. When the new fin 3 is opened, the old fin 3 is reset under the action of the torsion spring 303. The rhomboid block 302 drives the rotating shaft 301 to reverse. The solid section of the sealing bolt 603 re-seals the secondary pipe 602 to prevent the upper hot airflow from being drawn away again. This process is repeated until the temperature of the left and right physical processing furnaces 2 tends to be balanced. As the temperature of the physical processing furnace 2 on the right rises and heat is exchanged, the physical processing furnace 2 on the right is started to physically heat the glass plate inside the physical processing furnace 2. After the temperature information is fed back, the appropriate corresponding furnace is selected between the two chemical processing furnaces 7 above to put the product in. The isolation plate 8 on the right is opened again. After the transfer is completed, the isolation plate 8 is closed, and chemical ion exchange is carried out to turn ordinary glass into tempered glass after chemical reaction. The idle status of the two chemical processing furnaces 7 is monitored in real time by sensors. When a chemical processing furnace 7 has completed the processing of the previous batch of workpieces and is in the waiting state for feeding, it sends a feeding signal to the corresponding physical processing furnace 2. The processing process of the glass plate by the physical processing furnace 2 and the chemical processing furnace 7 and the docking process are all well known technologies in this field, so they will not be described in detail. Finally, the cycle operation phase begins. After the first round of layered heat exchange is completed, reverse layered heat exchange begins. The right fin 3 opens layer by layer from bottom to top, and the left fin 3 opens layer by layer from top to bottom. The hot airflow is directionally transported from the right side to the left side through the docking mechanism 6 and the heat exchange pipe 5, thus realizing a two-way cycle of heat dissipation and heat absorption, maximizing the recovery of waste heat.
