Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchangers, and specifically relates to a heat exchanger and an eddy current generator built therein. Background Art

[0002] A plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the heat exchange plates, and heat exchange is carried out through the heat exchange plates. Compared with conventional shell-and-tube heat exchangers, it has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, convenient installation and cleaning, wide application, long service life, etc.

[0003] For example, a plate heat exchanger disclosed in a Chinese patent with the application number 2023113223986 includes a first fixing plate. The upper and lower ends on one side of the first fixing plate are respectively fixedly installed with support rods, and a second fixing plate is fixedly installed on one side of the two support rods. The device seals the interior of the housing through a sealing component. During the simultaneous rotation of one ends of the three third transmission rods towards the middle, the hot water inside the housing respectively enters the three communication pipes, and is ejected from the other ends of the three communication pipes. The ejected water is ejected from the other side of the filter plate, and the particulate impurities attached to the filter plate are cleaned. At the same time, the cleaned impurities are discharged through the sewage pipe, effectively preventing the impurities in the hot water from entering the heat exchange plates, thereby increasing the service life of the heat exchange plates. However, the operation is complex and the cleaning efficiency is low.

[0004] Based on the above solution, when the fluid flows through the elbow and turns, the fluid will impact the inner wall of the elbow. If it lasts for a long time, the inner wall of the elbow will be worn.

[0005] In addition, the filter screen will vibrate under the action of the fluid, and the fluid drives the dirt to impact and collide with the filter screen. Therefore, if the fluid impact force is relatively large, the filter screen will be damaged, affecting the service life of the filter screen.

[0006] During the process of transporting the fluid, dirt will adhere and accumulate on the inner wall of the conveying pipe, thereby hindering the flow of the fluid in the conveying pipe. After long-term use, more dirt adheres to the surface of the filter screen, causing the filter screen to become blocked, affecting the normal flow of the fluid, and thus affecting the heat exchange efficiency of the heat exchanger.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The present invention changes the flow direction and velocity of the fluid in the pipe by setting up a vortex component. Under the combined action of multiple spoiler plates, the fluid in the pipe has a relatively large disturbance intensity, inducing vortices to destroy the flow boundary layer, reducing the thickness of the laminar sublayer, thereby reducing the heat transfer resistance, increasing the turbulence intensity, improving the field synergy effect between the temperature field and the velocity field, enhancing heat transfer. At the same time, the fluid in the pipe forms a jet after passing through the through holes, reducing the stagnant fluid in the recirculation area behind the vortex component, promoting the formation of longitudinal vortices. At the same time, the through holes can also reduce the frictional resistance during the flow process, improving the overall thermal performance.

[0027] 2. The present invention buffers by setting up an adjusting plate to avoid the elbow inner wall being worn due to long-term fluid impact. By setting up a first adjusting component and a second adjusting component to adjust the tilt angle of the adjusting plate inside the elbow, changing the flow direction and flow rate of the fluid, so as to clean the dirt attached to different positions on the conveying pipe and the filter net, improving the cleaning effect and avoiding the influence of dirt accumulation on the heat transfer efficiency.

[0028] 3. The present invention sets up a detection spring to dampen vibration when the fluid or the fluid drives the dirt to impact and collide with the filter net, avoiding excessive impact force from damaging the filter net. And when cleaning the dirt by adjusting the tilt angle of the adjusting plate, the filter net deflects under the action of the fluid, thus serving the purpose of guiding the fluid, and increasing the jet to facilitate strengthening the turbulence effect in the conveying pipe.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figures 1 to 11 shown, a heat exchanger of the present invention includes a heat exchanger assembly 1. The heat exchanger assembly 1 includes a heat exchanger body and an elbow 111. A delivery pipe 110 is provided on one side of the elbow 111, a pipe body 112 is provided on the side of the elbow 111 away from the delivery pipe 110, a filter assembly 2 is provided inside the delivery pipe 110, and a first adjustment assembly 4 and a second adjustment assembly 5 are provided on the elbow 111.

[0043] As Figure 2 、 Figure 3As shown in the figure, the heat exchanger body includes a fixed clamping plate 101, heat exchange fins 102, and a movable clamping plate 103. The heat exchange fins 102 are arranged between the fixed clamping plate 101 and the movable clamping plate 103. One end of the fixed clamping plate 101 is provided with a guide rod 104. A fixed support 105 is arranged at the end of the guide rod 104 away from the fixed clamping plate 101. The number of guide rods 104 is two, and the two guide rods 104 are respectively arranged at the upper and lower ends of the heat exchange fins 102. A limit groove is arranged at the position where the guide rod 104 is connected to the heat exchange fins 102. By arranging the guide rod 104, it is used to support and limit the heat exchange fins 102. The guide rod 104 penetrates and extends to the outside of the fixed support 105. Screws are arranged on both sides of the movable clamping plate 103. The movable clamping plate 103 is connected to the fixed clamping plate 101 through the screws. Through the cooperation of the movable clamping plate 103, the fixed clamping plate 101, and the screws, a plurality of heat exchange fins 102 are clamped and fixed.

[0044] As Figure 3 shown in the figure, a heat flow inlet pipe 106 is arranged at the end of the fixed clamping plate 101 away from the heat exchange fins 102. One end of the heat flow inlet pipe 106 away from the fixed clamping plate 101 is connected to a conveying pipe 110. A heat flow outlet pipe 107 is arranged below the heat flow inlet pipe 106. A cold flow outlet pipe 109 is arranged on one side of the heat flow inlet pipe 106. A cold flow inlet pipe 108 is arranged below the cold flow outlet pipe 109. A heat flow inlet is opened at the position where the fixed clamping plate 101 is connected to the heat flow inlet pipe 106. A heat flow outlet is opened at the position where the fixed clamping plate 101 is connected to the heat flow outlet pipe 107. A cold flow inlet is opened at the position where the fixed clamping plate 101 is connected to the cold flow inlet pipe 108. A cold flow outlet is opened at the position where the fixed clamping plate 101 is connected to the cold flow outlet pipe 109.

[0045] As Figure 4 、 Figure 5 shown in the figure, the filtering component 2 includes a filter net 201. The filter net 201 is arranged inside the conveying pipe 110. An installation ring 202 is arranged on one side of the filter net 201. An installation groove is opened at the position where the installation ring 202 is connected to the conveying pipe 110. A fixing plate 203 is arranged on the side of the filter net 201 away from the installation ring 202. By arranging the filter net 201, it is avoided that dirt and impurities in the hot fluid enter the heat exchange fins 102 through the heat flow inlet pipe 106, affecting the heat exchange efficiency.

[0046] As Figure 6 、 Figure 7As shown in the figure, the present invention also provides a vortex generator. Inside the pipe body 112, there is a vortex component 3. The vortex component 3 includes a spoiler group. The spoiler group includes two spoiler vanes 301. Through holes 302 are arranged on the surface of the spoiler vanes 301, so that the fluid in the pipe body 112 forms a jet after passing through the through holes 302, and the frictional resistance during the flow process is also reduced. The two spoiler vanes 301 are symmetrically arranged. The spoiler vanes 301 are triangular. There are multiple spoiler groups, and the multiple spoiler groups are annularly arranged inside the pipe body 112. There are multiple vortex components 3, and the multiple vortex components 3 are arranged at intervals along the axial direction of the pipe body 112. By arranging the vortex component 3, the movement direction and speed of the fluid in the pipe body 112 are changed, so that the disturbance intensity of the fluid in the pipe body 112 is relatively large, longitudinal vortices are better formed, and vortices are induced to destroy the flow boundary layer, thereby reducing the heat transfer resistance, increasing the turbulence intensity, improving the field synergy effect of the temperature field and the velocity field, and strengthening the heat transfer.

[0047] During use, when the hot fluid sequentially passes through the pipe body 112, the elbow 111, the delivery pipe 110, and the hot fluid inlet pipe 106 and enters the channel between the heat exchange fins 102, due to water quality problems, dirt will be generated when the hot fluid is heated. After long-term use, a large amount of dirt remains between the heat exchange fins 102, and the heat exchange efficiency is poor. The dirt in the hot fluid is filtered by the filter screen 201, so that the dirt entering between the heat exchange fins 102 is reduced, and the heat exchange effect is enhanced. At the same time, the cold fluid enters the channel between the heat exchange fins 102 through the cold fluid inlet pipe 108. Thus, the hot fluid and the cold fluid exchange heat through the heat exchange fins 102. After the exchange is completed, the hot fluid and the cold fluid come out from the hot fluid outlet pipe 107 and the cold fluid outlet pipe 109 respectively.

[0048] In order to improve the heat exchange efficiency, by arranging the vortex component 3 to change the movement direction and speed of the fluid in the pipe body 112, under the combined action of multiple spoiler vanes 301, the disturbance intensity of the fluid in the pipe body 112 is relatively large, longitudinal vortices are better formed, and vortices are induced to destroy the flow boundary layer, reducing the thickness of the laminar sublayer, thereby reducing the heat transfer resistance, increasing the turbulence intensity, improving the field synergy effect of the temperature field and the velocity field, and strengthening the heat transfer. By arranging through holes 302 on the spoiler vanes 301, the fluid in the pipe body 112 forms a jet after passing through the through holes 302. The jet affects the recirculation area behind the vortex component 3, reduces the stagnant fluid in this area, and promotes the formation of longitudinal vortices. At the same time, the through holes 302 can also reduce the frictional resistance during the flow process, thereby reducing the frictional loss and improving the overall thermal performance.

[0049] It not only promotes the generation of longitudinal vortices, but also forms a jet-like fluid acceleration zone, thins the boundary layer, enhances the fluid mixing, thereby strengthening the heat exchange. At the same time, through the jet, the mixing degree with the mainstream is enhanced, and it is further mixed under the action of the central fluid, thereby improving the mixing efficiency of the hot and cold fluids in the channel between the heat exchange fins 102.

[0050] During the above process, when the fluid turns through the elbow 111, the fluid will impact the inner wall of the elbow 111. If this continues for a long time, it will cause wear on the inner wall of the elbow 111. The filter screen 201 will vibrate under the action of the fluid, and the fluid will drive the dirt to impact and collide with the filter screen 201. Therefore, if the impact force of the fluid is relatively large, it will damage the filter screen 201 and affect the service life of the filter screen 201. During the process of transporting the fluid, dirt will adhere and accumulate on the inner wall of the conveying pipe 110, thereby hindering the flow of the fluid in the conveying pipe 110. After long-term use, a large amount of dirt will adhere to the surface of the filter screen 201, causing the filter screen 201 to become blocked, affecting the normal flow of the fluid, and thus affecting the heat exchange efficiency of the heat exchanger.

[0051] To solve the above problems, the heat exchanger further includes:

[0052] As Figure 8 shown, an adjusting plate 113 is provided inside the elbow 111. The adjusting plate 113 is arc-shaped, and elastic strips 114 are provided at both ends of the adjusting plate 113. By providing the elastic strips 114, the adjusting plate 113 can adapt to the inner wall of the elbow 111 in different states.

[0053] As Figure 9 、 Figure 10 shown, the first adjusting assembly 4 includes a first mounting seat 401. First magnetic seats 402 are provided at both ends of the first mounting seat 401. A first support cylinder 403 is provided on one side of the first magnetic seat 402. A first adjusting spring 404 is provided inside the first support cylinder 403. A first adjusting rod 405 is provided at the end of the first adjusting spring 404 away from the first support cylinder 403.

[0054] The first magnetic seat 402 is provided on the outer surface of the elbow 111. The first support cylinder 403 is provided inside the elbow 111. One end of the first support cylinder 403 close to the first magnetic seat 402 is connected to the inner wall of the elbow 111. The end of the first adjusting rod 405 away from the first support cylinder 403 is connected to the adjusting plate 113 through a hinge seat.

[0055] As Figure 9 、 Figure 10 shown, the second adjusting assembly 5 includes a second mounting seat 501. Second magnetic seats 502 are provided at both ends of the second mounting seat 501. A second support cylinder 503 is provided on one side of the second magnetic seat 502. A second adjusting spring 504 is provided inside the second support cylinder 503. A second adjusting rod 505 is provided at the end of the second adjusting spring 504 away from the second support cylinder 503.

[0056] The second magnetic base 502 is disposed on the outer surface of the elbow 111, the second support cylinder 503 is disposed inside the elbow 111, one end of the second support cylinder 503 close to the second magnetic base 502 is connected to the inner wall of the elbow 111, and one end of the second adjusting rod 505 away from the second support cylinder 503 is connected to the adjusting plate 113 through a hinge seat.

[0057] Electromagnets are disposed inside both the first magnetic base 402 and the second magnetic base 502, and magnetic blocks are disposed inside both the first adjusting rod 405 and the second adjusting rod 505.

[0058] During use, the controller controls the electromagnet inside the first magnetic base 402 to enhance the magnetic repulsion force between the electromagnet and the magnetic block inside the first adjusting rod 405, that is, a magnetic repulsion force is generated between the first magnetic base 402 and the first adjusting rod 405. Under the action of the magnetic repulsion force, the first adjusting spring 404 is stretched. During this process, the first adjusting rod 405 drives the first adjusting spring 404 to move away from the first support cylinder 403, thereby pushing the adjusting plate 113 and increasing the supporting height of the first adjusting rod 405 on the adjusting plate 113 at this position.

[0059] Similarly, the controller controls the electromagnet inside the second magnetic base 502 to enhance the magnetic repulsion force between the electromagnet and the magnetic block inside the second adjusting rod 505, that is, a magnetic repulsion force is generated between the second magnetic base 502 and the second adjusting rod 505. Under the action of the magnetic repulsion force, the second adjusting spring 504 is stretched. During this process, the second adjusting rod 505 drives the second adjusting spring 504 to move away from the second support cylinder 503, thereby pushing the adjusting plate 113 and increasing the supporting height of the second adjusting rod 505 on the adjusting plate 113 at this position.

[0060] As Figure 5 shown, a detection spring 204 is disposed on one side of the fixing plate 203. One end of the mounting ring 202 close to the filter net 201 is connected to the fixing plate 203, and one end of the detection spring 204 away from the fixing plate 203 is connected to the filter net 201. The number of the detection springs 204 is four, and the four detection springs 204 are annularly disposed on the fixing plate 203. A plurality of pressure sensors are disposed on the fixing plate 203, and the pressure sensors correspond to the positions of the detection springs 204 on the fixing plate 203.

[0061] During use, since the filter net 201 will vibrate under the action of the fluid, the detection spring 204 is provided to damp the vibration of the filter net 201, and the pressure sensors are provided to detect the pressure magnitudes received by different parts of the filter net 201.

[0062] When the fluid flows through the elbow 111, the fluid will impact the inner wall of the elbow 111. If this persists for a long time, it will cause wear to the inner wall of the elbow 111. To solve this problem, a regulating plate 113 is provided inside the elbow 111 for buffering, so that the fluid impacts the regulating plate 113, thereby blocking the direct impact of the fluid on the inner wall of the elbow 111. At the same time, it can also split the fluid flow, increase the buffering space, and avoid the wear of the inner wall of the elbow 111 caused by the long-term fluid impact, which affects the service life of the elbow 111.

[0063] When the fluid passes through the filter screen 201 for filtration, since the filter screen 201 will vibrate under the action of the fluid, the fluid drives the dirt to impact and collide with the filter screen 201. Therefore, if the fluid impact force is relatively large, it will damage the filter screen 201 and affect the service life of the filter screen 201. To solve this problem, by setting the detection spring 204, the filter screen 201 is buffered and vibration-damped during the process of fluid impact or dirt impact, avoiding the wear of the filter screen 201 caused by the large impact force of the dirt on the filter screen 201 under the action of the fluid, and improving the service life of the filter screen 201.

[0064] During the process of transporting the fluid, dirt will adhere and accumulate on the inner wall of the delivery pipe 110, thereby hindering the flow of the fluid in the delivery pipe 110. After long-term use, a large amount of dirt adheres to the surface of the filter screen 201, causing the filter screen 201 to become blocked, affecting the normal flow of the fluid, and thus affecting the heat exchange efficiency of the heat exchanger. To solve this problem, specifically, since dirt will adhere to the surface of the filter screen 201 and the dirt adhesion conditions at different positions are different, the deformation amount of the detection spring 204 at that place is also different. The deformation amount of the detection spring 204 at that place is detected by the pressure sensor at that place, that is, the blockage conditions of different positions of the filter screen 201 are judged by the detection value of the pressure sensor. Then, through the cooperation of the first adjustment component 4 and the second adjustment component 5, the inclination angle of the regulating plate 113 is adjusted, thereby changing the direction of the fluid in the delivery pipe 110.

[0065] When it is necessary to clean the dirt attached to the inner bottom wall of the delivery pipe 110 or when the detected value of the pressure sensor at the lower end of the fixing plate 203 exceeds the preset value, it indicates that due to the fluid in the delivery pipe 110 under the action of gravity, the fluid drives the dirt to accumulate in the lower half of the filter net 201, resulting in blockage and hindrance to the fluid, making the pressure on the detection spring 204 at this position the largest, and there will also be dirt accumulation on the inner bottom wall of the delivery pipe 110. Then, the controller simultaneously controls the electromagnets inside the two first magnetic seats 402 on the first adjustment assembly 4 and reduces the magnetic force of the electromagnets, that is, weakens the magnetic repulsion force between the electromagnets and the magnetic blocks inside the first adjustment rod 405, that is, a magnetic repulsion force is generated between the first magnetic seat 402 and the first adjustment rod 405. Under the action of the magnetic repulsion force, the first adjustment spring 404 is compressed. During this process, the first adjustment rod 405 drives the first adjustment spring 404 to move towards the first support cylinder 403, thereby pulling the adjustment plate 113 and reducing the support height of the first adjustment rod 405 on the adjustment plate 113 at this position, so that the end of the adjustment plate 113 close to the filter net 201 tilts downward, making the fluid flow downward along the inclination angle of the adjustment plate 113, increasing the impact force of the fluid on the inner bottom wall of the delivery pipe 110. Under the action of the fluid, not only can the dirt on the inner bottom wall of the delivery pipe 110 be flushed and cleaned, but also the lower half of the filter net 201 can be flushed and cleaned, avoiding blockage of the filter net 201 and affecting fluid flow.

[0066] When it is necessary to clean the dirt attached to the inner wall of the conveying pipe 110, that is, to clean the dirt attached to the left inner wall or the right inner wall of the conveying pipe 110. Specifically, when it is necessary to clean the dirt attached to the right inner wall of the conveying pipe 110, the controller controls the electromagnet inside the left first magnetic seat 402 in the first adjustment assembly 4 and increases the magnetic force of the electromagnet, that is, increases the magnetic repulsion force between the electromagnet and the magnet block inside the first adjustment rod 405, that is, a magnetic repulsion force is generated between the first magnetic seat 402 and the first adjustment rod 405. Under the action of the magnetic repulsion force, the first adjustment spring 404 is stretched. During this process, the first adjustment rod 405 drives the first adjustment spring 404 to move away from the first support cylinder 403, thereby pushing the adjustment plate 113 and increasing the support height of the first adjustment rod 405 at this position on the adjustment plate 113. At the same time, the controller controls the electromagnet inside the left second magnetic seat 502 in the second adjustment assembly 5 and increases the magnetic force of the electromagnet, that is, increases the magnetic repulsion force between the electromagnet and the magnet block inside the second adjustment rod 505. Under the action of the magnetic repulsion force, the second adjustment spring 504 is stretched. During this process, the second adjustment rod 505 drives the second adjustment spring 504 to move away from the second support cylinder 503, thereby pushing the adjustment plate 113 and increasing the support height of the second adjustment rod 505 at this position on the adjustment plate 113, so that the adjustment plate 113 tilts to the right. During this process, the elastic strip 114 deforms and always contacts the inner wall of the conveying pipe 110, increasing the flushing force of the fluid on the dirt attached to the right inner wall of the conveying pipe 110 and improving the cleaning effect.

[0067] At the same time, under the action of the fluid, the detection spring 204 on the right side of the filter screen 201 is compressed, so that the filter screen 201 deflects, concentrating the flow of the fluid in the conveying pipe 110, thereby enhancing the jet flow of the fluid through the filter screen 201, improving the turbulence effect of the fluid, facilitating the cleaning of the dirt attached to the filter screen 201 under the action of the fluid, and improving the cleaning effect.

[0068] It should be noted that in the above process, by controlling the magnetic force of the electromagnet on the first magnetic base 402 through the controller, the distance that the first adjusting rod 405 on the first adjusting assembly 4 extends out of the first support cylinder 403 can be controlled, that is, the supporting height of the first adjusting rod 405 on the adjusting plate 113 is changed. Similarly, by controlling the magnetic force of the electromagnet on the second magnetic base 502 through the controller, the distance that the second adjusting rod 505 on the second adjusting assembly 5 extends out of the second support cylinder 503 can be controlled, that is, the supporting height of the second adjusting rod 505 on the adjusting plate 113 is changed. Then, through the cooperation of the first adjusting assembly 4 and the second adjusting assembly 5, the inclination degree of the adjusting plate 113 can be adjusted according to different situations, thereby changing the movement direction and flow rate of the fluid, so as to clean the dirt attached to different positions on the conveying pipe 110 and the filter net 201, improve the cleaning effect, and avoid the influence of dirt accumulation on the heat exchange efficiency.
