Description

Technical Field

[0001] This invention belongs to the field of heat exchanger technology, specifically a heat exchanger with a turbulence structure, a heat exchange method, and its application in heat exchange equipment. Background Technology

[0002] A heat exchanger, also known as a heat exchanger, is an energy-saving device that enables heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters of the process to meet the requirements of the process conditions. It is also one of the main devices for improving energy efficiency. The heat exchanger industry involves nearly 30 industries, including HVAC, pressure vessels, wastewater treatment equipment, chemical industry, and petroleum industry, and has a wide range of applications.

[0003] For example, Chinese patent application number 2018114268841 discloses a tubular heat exchanger with turbulence, including a tube shell, tube sheet, multiple fins, multiple baffles and cooling tube bundle. However, the heat exchange efficiency is low, it is not easy to adjust, and it produces dirt after long-term use, which is not easy to clean.

[0004] For example, Chinese Patent Application No. 2023113684785 discloses a tubular heat exchanger, including a shell with a hot medium inlet, a hot medium outlet, a cold medium inlet, and a cold medium outlet. Multiple tube bundles are detachably assembled inside the shell. Hot flow enters the tube bundle through the hot medium inlet, flows through the tube bundle, and exits from the hot medium outlet. Cold flow enters the shell through the cold medium inlet, flows through the outside of the tube bundle, and exits from the cold medium outlet. The cold and hot flows exchange heat through the tube bundles. However, when the flow rate of the fluid passing through the tube bundles is too fast, vibration will occur, which can easily cause the tube bundles to deform and be damaged.

[0005] Based on the above solution, since the fluid will generate eddies during the process of passing through the heat exchange tube, and when the flow rate of the fluid through the heat exchange tube is too fast, the heat exchange tube will vibrate. Excessive vibration will also cause friction and collision between the heat exchange tube and the upper and lower baffles, resulting in deformation and damage of the heat exchange tube and reducing the service life of the heat exchange tube.

[0006] Meanwhile, during the heat exchange process, due to the presence of multiple flow dead zones inside the shell, insufficient heat exchange can easily occur when the flow rate and velocity of the fluid inside the heat exchange tube are low.

[0007] Due to prolonged use, dirt easily accumulates on the surface of the heat exchange tubes or the inner wall of the shell, which cannot be cleaned in time. Excessive dirt will affect the heat exchange effect and result in low heat exchange efficiency. Summary of the Invention

[0015] A second circular hole is provided at the position where the heat exchange tube connects to the lower baffle. A second conical scraper ring is provided inside the second circular hole. The heat exchange tube passes through the second scraper ring and extends to the outside of the lower baffle.

[0016] Preferably, a first end cap is provided at one end of the housing, a second end cap is provided at the end of the housing away from the first end cap, and a support is provided at the bottom of the housing;

[0017] The surface of the first end cap is provided with a cold flow inlet, the surface of the second end cap is provided with a cold flow outlet, the surface of the housing is provided with a hot flow inlet, and the end of the housing away from the hot flow inlet is provided with a hot flow outlet.

[0018] Preferably, the shell is provided with a first tube sheet and a second tube sheet, which are respectively disposed at both ends of the heat exchange tube.

[0019] There are two upper flow deflectors and two lower flow deflectors, and the upper and lower flow deflectors are arranged alternately between the first tube sheet and the second tube sheet.

[0020] Preferably, the first adjustment component includes a first electrically controlled telescopic rod, which is disposed at one end of the first tube sheet.

[0021] The first mounting rod movably passes through the upper baffle plate located near the first tube sheet, and the output shaft of the first electrically controlled telescopic rod is connected to the lower baffle plate located near the first tube sheet.

[0022] Preferably, the second adjustment component includes a second electrically controlled telescopic rod, which is disposed at one end of the second tube sheet, and a second mounting rod is disposed below the second electrically controlled telescopic rod, with a second spring disposed on the surface of the second mounting rod;

[0024] A heat exchange method for a heat exchanger with a turbulence-inducing structure, the specific steps of which are as follows:

[0025] S1: First, hot and cold fluids are introduced into the shell and heat exchange tube of the heat exchange component respectively. Under the flow of the two fluids, heat transfer will occur between the two fluids. Under the action of the triangular fins, the fluid in the heat exchange tube will have enhanced turbulence and improve the heat transfer efficiency.

[0026] S2: Then, based on the different conditions of the fluid inside the heat exchange tube, the positions of the upper and lower baffles in the baffle assembly are adjusted by the cooperation of the first and second adjustment components to change the direction and velocity of the fluid inside the shell and improve the intensity and efficiency of heat exchange.

[0027] S3: Finally, through the cooperation of the first and second adjustment components, the upper and lower baffles move back and forth on the heat exchange tubes to clean the dirt on the surface of the heat exchange tubes or the inner wall of the shell, thus avoiding a reduction in heat exchange efficiency.

[0028] The present invention also provides the application of a heat exchanger with a turbulence structure as described above in a heat exchange device.

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

[0030] 1. This invention, by setting up a turbulence structure, generates longitudinal vortices in the fluid inside the heat exchange tube. Under the action of the vortex, the turbulence intensity of the fluid near the inner wall of the heat exchange tube increases, thereby making the fluid in different parts of the heat exchange tube more uniformly mixed, significantly enhancing the mixing rate of the fluid inside the heat exchange tube, destroying the boundary layer and increasing the turbulence intensity of the fluid inside the tube, thus achieving the purpose of enhancing heat transfer.

[0031] 2. The present invention uses pressure sensors on the first and second detection scraping rings to detect the vibration amplitude at different positions of the heat exchange tube. The magnitude of the vibration of the heat exchange tube is determined by comparing the difference between the detected value of the pressure sensor and the preset value. The positions of the upper and lower baffles on the heat exchange tube are adjusted by the cooperation of the first and second electrically controlled telescopic rods to increase the natural frequency of the heat exchange tube and reduce the vibration of the heat exchange tube.

[0032] 3. The present invention uses pressure sensors on the first and second detection scraping rings to detect the vibration amplitude at different positions of the heat exchange tube, determine the flow rate in the heat exchange tube, and adjust the distance between the upper and lower baffles by cooperating with the first and second electrically controlled telescopic rods to improve the heat exchange effect.

[0033] 4. The present invention uses the cooperation of the first electrically controlled telescopic rod and the second electrically controlled telescopic rod to make the upper baffle and the lower baffle reciprocate on the heat exchange tube, thereby scraping and cleaning the dirt on the surface of the heat exchange tube by the first detection scraping ring, the second detection scraping ring, the first conical scraping ring and the second conical scraping ring, and at the same time, the upper baffle and the lower baffle scraping and cleaning the dirt on the inner wall of the shell.

[0046] 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.

[0047] like Figures 1 to 11 As shown, a heat exchanger with a turbulence structure according to the present invention includes a heat exchange component 1, which includes a shell 101 and a heat exchange tube 102. A baffle component 2 is provided inside the shell 101, and a first regulating component 3 and a second regulating component 4 are respectively provided at both ends of the baffle component 2.

[0048] like Figure 2 , Figure 3As shown, a first end cap 103 is provided at one end of the housing 101, and a second end cap 104 is provided at the end of the housing 101 away from the first end cap 103. A support 111 is provided at the bottom of the housing 101 to support and fix the housing 101. A cold flow inlet 107 is provided on the surface of the first end cap 103, and a cold flow outlet 108 is provided on the surface of the second end cap 104. The cold flow inlet 107 and the cold flow outlet 108 are provided for the entry and exit of fluid inside the heat exchange tube 102. A hot flow inlet 109 is provided on the surface of the housing 101, and a second end cap 104 is provided at the end of the housing 101 away from the hot flow inlet 109. A heat flow outlet 110 is provided. By providing a heat flow inlet 109 and a heat flow outlet 110, the external fluid of the heat exchange tube 102 can enter and exit, thereby realizing the heat transfer between the internal fluid of the heat exchange tube 102 and the external fluid of the heat exchange tube 102. The shell 101 is provided with a first tube sheet 105 and a second tube sheet 106. The first tube sheet 105 and the second tube sheet 106 are respectively provided at both ends of the heat exchange tube 102. Fixing holes are provided on the surface of the first tube sheet 105 and the second tube sheet 106. The fixing holes are adapted to the heat exchange tube 102. The first tube sheet 105 and the second tube sheet 106 are used to fix the heat exchange tube 102.

[0049] like Figures 8 to 10 As shown, the baffle assembly 2 includes an upper baffle 201 and a lower baffle 202, which are used to increase the fluid velocity outside the heat exchange tube 102. A first circular hole 2011 is provided at the position where the heat exchange tube 102 connects to the upper baffle 201, and a second circular hole 2021 is provided at the position where the heat exchange tube 102 connects to the lower baffle 202. By providing the first circular hole 2011 and the second circular hole 2021, the heat exchange tube 102 can pass through the upper baffle 201 or the lower baffle 202. There are two upper baffles 201 and two lower baffles 202, and the upper baffles 201 and the lower baffles 202 are arranged alternately between the first tube sheet 105 and the second tube sheet 106.

[0050] like Figure 4 As shown, the heat exchange tube 102 is provided with a turbulence structure inside. The turbulence structure includes triangular fins 1021. There are multiple triangular fins 1021 arranged in a ring on the inner wall of the heat exchange tube 102. There are multiple turbulence structures arranged linearly inside the heat exchange tube 102. The surface of the triangular fins 1021 is provided with circular holes.

[0051] During operation, when the heat exchanger is exchanging heat, the hot flow enters the interior of the shell 101 from the hot flow inlet 109 and then exits from the hot flow outlet 110. The cold flow enters the first end cover 103 from the cold flow inlet 107 and then enters the heat exchange tube 102. The cold flow is then guided to the second end cover 104 by the turbulence structure formed by the triangular fins 1021 inside the heat exchange tube 102. During this process, the hot fluid in the shell 101 exchanges heat with the cold fluid in the heat exchange tube 102 through the tube wall.

[0052] To improve heat transfer efficiency, a turbulence structure is installed inside the heat exchange tube 102. When the fluid flows inside the heat exchange tube 102, it collides with the triangular vanes 1021 inside the heat exchange tube 102. Under the action of multiple triangular vanes 1021, multi-scale longitudinal vortices are induced in the fluid inside the heat exchange tube 102. The longitudinal vortices are parallel to the flow direction, generating a vortex entrainment effect, which carries the fluid near the wall surface downwards towards the center of the flow area. Under the action of the vortex, the turbulence intensity of the fluid near the inner wall of the heat exchange tube 102 increases, thereby making the fluid in different parts of the heat exchange tube 102 more uniformly mixed, significantly enhancing the mixing rate of the fluid inside the heat exchange tube 102, destroying the boundary layer and increasing the turbulence intensity of the fluid inside the tube, thus achieving the purpose of enhanced heat transfer.

[0053] Meanwhile, by setting circular holes on the surface of the triangular fin 1021, the fluid in the heat exchange tube 102 forms a jet after passing through the small holes, reducing stagnant fluid in the recirculation area and enhancing heat transfer. In addition, the circular holes can also reduce frictional resistance during the flow process, thereby reducing frictional loss and improving the overall thermal performance.

[0054] During the above process, eddies are generated as the fluid passes through the heat exchange tube 102. When the flow rate of the fluid through the heat exchange tube 102 is too fast, the heat exchange tube 102 will vibrate. Excessive vibration can also cause friction and collision between the heat exchange tube 102 and the upper and lower baffles 201, resulting in deformation and damage to the heat exchange tube 102 and reducing its service life. At the same time, during the heat exchange process, due to the presence of multiple flow dead zones inside the shell 101, insufficient heat exchange can easily occur when the flow rate and velocity of the fluid inside the heat exchange tube 102 are low. Due to prolonged use, dirt can easily accumulate on the surface of the heat exchange tube 102 or the inner wall of the shell 101, which cannot be cleaned in time. Excessive dirt will affect the heat exchange effect and result in low heat exchange efficiency.

[0055] To address the aforementioned issues, the heat exchanger also includes:

[0056] like Figure 9 , Figure 10As shown, a first detection scraper ring 2013 is provided on one side of the upper baffle 201, and a second detection scraper ring 2023 is provided on one side of the lower baffle 202. Pressure sensors are provided inside both the first detection scraper ring 2013 and the second detection scraper ring 2023.

[0057] The first circular hole 2011 is provided with a first conical scraper ring 2012 inside, and the heat exchange tube 102 passes through the first detection scraper ring 2013 and extends to the outside of the upper baffle 201. The second circular hole 2021 is provided with a second conical scraper ring 2022 inside, and the heat exchange tube 102 passes through the second detection scraper ring 2023 and extends to the outside of the lower baffle 202.

[0058] In use, a pressure sensor is set to detect the vibration level of the heat exchange tube 102 during the heat exchange process. In addition, a first detection scraper ring 2013, a second detection scraper ring 2023, a first conical scraper ring 2012, and a second conical scraper ring 2022 are set to scrape and clean the dirt on the surface of the heat exchange tube 102. An upper baffle 201 and a lower baffle 202 are set to scrape and clean the dirt on the inner wall of the shell 101.

[0059] like Figures 5 to 7 , Figure 11 As shown, the first adjustment component 3 includes a first electrically controlled telescopic rod 301, which is disposed at one end of the first tube sheet 105. A first mounting rod 302 is disposed above the first electrically controlled telescopic rod 301. A first spring 303 is disposed on the surface of the first mounting rod 302. The first mounting rod 302 movably passes through the upper baffle 201 located near the first tube sheet 105. The output shaft of the first electrically controlled telescopic rod 301 is connected to the lower baffle 202 located on the side near the first tube sheet 105.

[0060] The second adjustment component 4 includes a second electrically controlled telescopic rod 401, which is disposed at one end of the second tube sheet 106. A second mounting rod 402 is disposed below the second electrically controlled telescopic rod 401. A second spring 403 is disposed on the surface of the second mounting rod 402. The second mounting rod 402 movably passes through the lower baffle 202 located near the second tube sheet 106. The output shaft of the second electrically controlled telescopic rod 401 is connected to the upper baffle 201 located on the side near the second tube sheet 106.

[0061] In use, the controller controls the extension of the first electrically controlled telescopic rod 301, which pushes the lower baffle 202 located near the first tube sheet 105 to move together, thereby adjusting the position of the lower baffle 202 on the heat exchange tube 102. Similarly, the controller controls the extension of the second electrically controlled telescopic rod 401, which pushes the upper baffle 201 located near the second tube sheet 106 to move together, thereby adjusting the position of the upper baffle 201 on the heat exchange tube 102.

[0062] During the heat exchange process, eddies are generated as the fluid passes through the heat exchange tube 102, causing impact and vibration in the tube. Pressure sensors on the first and second detection scraper rings 2013 and 2023 detect the vibration amplitude at different locations on the heat exchange tube 102. The magnitude of the vibration is determined by comparing the difference between the pressure sensor readings and preset values. Specifically:

[0063] When the difference between the pressure sensor's detected value and the preset value is within the standard range, it indicates that the pressure exerted by the first detection scraper ring 2013 and the second detection scraper ring 2023 on the heat exchange tube 102 is within the normal range, and the vibration of the heat exchange tube 102 does not affect the normal heat exchange process.

[0064] When the difference between the pressure sensor reading and the preset value exceeds the standard range, it indicates that the first and second detection scraper rings 2013 and 2023 are under significant pressure from the heat exchange tube 102, and the heat exchange tube 102 is vibrating excessively. To address this issue, the controller extends the first electrically controlled telescopic rod 301. During this process, the first electrically controlled telescopic rod 301 pushes the lower baffle 202 located near the first tube sheet 105 to move together, and moves towards the second electrically controlled telescopic rod 401, thereby adjusting the position of the lower baffle 202 on the heat exchange tube 102. Simultaneously, the controller extends the second electrically controlled telescopic rod 401, which pushes the upper baffle 202 located near the second tube sheet 106 to move together. The baffle 201 moves together and moves towards the first electrically controlled telescopic rod 301, thereby adjusting the position of the upper baffle 201 on the heat exchange tube 102. Through the cooperation of the first electrically controlled telescopic rod 301 and the second electrically controlled telescopic rod 401, the distance between the upper baffle 201 and the lower baffle 202 at the middle position is shortened, so that the upper baffle 201 at the middle position cooperates with the adjacent lower baffle 202, thereby increasing the support force on the middle part of the heat exchange tube 102, increasing the natural frequency of the heat exchange tube 102, and reducing the vibration of the heat exchange tube 102. This avoids friction and collision between the heat exchange tube 102 and the upper and lower baffles 201 and the lower baffle 202 when the heat exchange tube 102 vibrates, which would cause the heat exchange tube 102 to deform and be damaged.

[0065] During the heat exchange process, the flow rate of the fluid inside the heat exchange tube 102 can be determined by the vibration amplitude of the heat exchange tube 102, thereby judging the heat exchange effect of the fluid inside the heat exchange tube 102. The vibration amplitude of the heat exchange tube 102 during normal heat exchange is set, and the value detected by the pressure sensor at this time is called the preset value. If the value detected by the pressure sensor exceeds or falls below the preset value, it indicates that the heat exchange tube 102 cannot achieve sufficient heat exchange. To improve the heat exchange effect, specifically:

[0066] If the pressure sensor reading is less than the preset value, it indicates that the fluid flow rate inside the heat exchange tube 102 is too low and the vibration amplitude of the heat exchange tube 102 is small. In this case, the heat exchange tube 102 cannot achieve sufficient heat exchange. However, to improve the heat transfer effect, the controller controls the first electrically controlled telescopic rod 301 to extend. The first electrically controlled telescopic rod 301 pushes the lower baffle 202 located near the first tube sheet 105 to move together and towards the second electrically controlled telescopic rod 401. Simultaneously, the controller controls the second electrically controlled telescopic rod 401 to extend, and the second electrically controlled telescopic rod 401 pushes the upper baffle 201 located near the second tube sheet 106... The fluid begins to move and moves towards the first electrically controlled telescopic rod 301, shortening the distance between the upper baffle 201 and the lower baffle 202 at the middle position. This causes the upper baffle 201 and the lower baffle 202 to be evenly distributed inside the shell 101. During this process, the fluid inside the shell 101 changes its flow direction periodically under the combined action of the upper baffle 201 and the lower baffle 202, forcing the fluid to deflect multiple times along a predetermined path. This increases the turbulence of the fluid inside the shell 101, effectively improving the efficiency of heat exchange. The dead zone area is significantly reduced, the pressure drop is significantly reduced, and the heat exchange efficiency is improved.

[0067] When the pressure sensor reading exceeds the preset value, it indicates that the fluid flow rate inside the heat exchange tube 102 is too high. Under the impact of the fluid, the vibration amplitude of the heat exchange tube 102 increases, preventing it from achieving sufficient heat exchange. To improve the heat transfer effect, the controller controls the first electrically controlled telescopic rod 301 to retract. The first electrically controlled telescopic rod 301 pulls the lower baffle 202 located near the first tube sheet 105, causing it to move away from the second electrically controlled telescopic rod 401. Simultaneously, the controller controls the second... When the second electrically controlled telescopic rod 401 retracts, it pulls the upper baffle 201 located near the second tube sheet 106 to move together and move away from the first electrically controlled telescopic rod 301. This increases the distance between the upper baffle 201 and the lower baffle 202 at the middle position, thereby reducing the turbulence of the fluid in the shell 101, reducing the heat exchange residence time, improving the heat exchange efficiency, and at the same time reducing the impact force of the fluid in the shell 101 on the heat exchange tube 102, thus enhancing the service life of the heat exchange tube 102.

[0068] Due to prolonged use, dirt easily accumulates on the surface of the heat exchange tube 102 or the inner wall of the shell 101, making it difficult to clean in a timely manner. Excessive dirt can also affect the heat exchange effect, resulting in low heat exchange efficiency. To solve this problem, the following measures are taken:

[0069] In the initial state, the fluid enters the interior of the housing 101 from the heat inlet 109, moves along the length of the housing 101 and is discharged from the heat outlet 110. Under the action of the fluid inside the housing 101, the first spring 303 is in a stretched state and the second spring 403 is in a compressed state.

[0070] When cleaning is required, the controller first controls the first electrically controlled telescopic rod 301 to extend, and at the same time controls the second electrically controlled telescopic rod 401 to retract, so that the upper baffle 201 and the lower baffle 202, which are in the middle position, move in the same direction on the heat exchange tube 102, moving towards the direction of the second tube sheet 106. During this process, the first detection scraper ring 2013 and the first conical scraper ring 2012 on the upper baffle 201 scrape and clean the dirt on the surface of the heat exchange tube 102, and the second detection scraper ring 2023 and the second conical scraper ring 2022 on the lower baffle 202 scrape and clean the dirt on the surface of the heat exchange tube 102. At the same time, the upper baffle 201 and the lower baffle 202 scrape and clean the dirt on the inner wall of the shell 101.

[0071] Under the action of the second electrically controlled telescopic rod 401, the second electrically controlled telescopic rod 401 drives the upper baffle 201 to squeeze the lower baffle 202 on the second mounting rod 402. At this time, the second spring 403 is compressed again. In this process, the lower baffle 202 on the second mounting rod 402 scrapes and cleans the dirt on the surface of the heat exchange tube 102 and the inner wall of the shell 101.

[0072] Then, the controller controls the first electrically controlled telescopic rod 301 to retract, and at the same time controls the second electrically controlled telescopic rod 401 to extend, so that the upper baffle 201 and the lower baffle 202, which are in the middle position, move away from the second tube sheet 106 on the heat exchange tube 102. Similarly, the first detection scraper ring 2013 and the first conical scraper ring 2012 on the upper baffle 201 scrape and clean the dirt on the surface of the heat exchange tube 102, and the second detection scraper ring 2023 and the second conical scraper ring 2022 on the lower baffle 202 scrape and clean the dirt on the surface of the heat exchange tube 102. At the same time, the upper baffle 201 and the lower baffle 202 scrape and clean the dirt on the inner wall of the shell 101.

[0073] Under the action of the first electrically controlled telescopic rod 301, the first electrically controlled telescopic rod 301 drives the lower baffle 202 to squeeze the upper baffle 201 on the first mounting rod 302. At this time, the first spring 303 changes from a stretched state to a compressed state. During this process, the upper baffle 201 on the first mounting rod 302 scrapes and cleans the dirt on the surface of the heat exchange tube 102 and the inner wall of the shell 101.

[0074] The first electrically controlled telescopic rod 301 and the second electrically controlled telescopic rod 401 work together to clean the surface of the heat exchange tube 102 or the inner wall of the shell 101 by the upper baffle 201 and the lower baffle 202, so as to avoid excessive dirt from affecting the heat exchange effect and causing low heat exchange efficiency.

[0075] When the fluid inside the housing 101 is discharged, under the action of the fluid, the first spring 303 returns from the stretched state to the initial state, and the second spring 403 returns from the compressed state to the initial state. During this process, the upper baffle 201 on the first mounting rod 302 and the lower baffle 202 on the second mounting rod 402 scrape and clean the dirt on the surface of the heat exchange tube 102 and the inner wall of the housing 101 again under the action of the first spring 303 and the second spring 403, respectively.

[0077] S1: First, hot and cold fluids are introduced into the shell 101 and heat exchange tube 102 of the heat exchange component 1, respectively. When the two fluids are flowing, heat transfer will occur between the two fluids. Under the action of the triangular fin 1021, the fluid in the heat exchange tube 102 will have enhanced turbulence and improve heat transfer efficiency.

[0078] S2: Then, according to the different conditions of the fluid in the heat exchange tube 102, the positions of the upper baffle 201 and the lower baffle 202 in the baffle assembly 2 are adjusted by the cooperation of the first adjustment component 3 and the second adjustment component 4, so as to change the direction and speed of the fluid in the shell 101 and improve the intensity and efficiency of heat exchange.

[0079] S3: Finally, by cooperating with the first adjustment component 3 and the second adjustment component 4, the upper baffle 201 and the lower baffle 202 reciprocate on the heat exchange tube 102 to clean the dirt on the surface of the heat exchange tube 102 or the inner wall of the shell 101, so as to avoid reducing the heat exchange efficiency.

[0080] The present invention discloses the application of a heat exchanger with a turbulence structure in heat exchange equipment. Specifically, it is used to realize heat transfer between two or more fluids at different temperatures, so that heat is transferred from the higher temperature fluid to the lower temperature fluid, thereby realizing heat exchange, so that the fluid temperature reaches the specified index of the process, and improving the heat transfer effect.
