Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, in particular to a heat transfer micro-channel heat exchange device. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc. They are widely used. Heat exchange devices are needed in the heat exchange process. For this reason, a Chinese patent discloses a dual-channel heat exchange device for pumping intermediate medium to enhance heat transfer. The application number is 202011047410.3. The patent realizes the circulation of the intermediate heat transfer medium between at least two parallel intermediate heat transfer medium cavities and the intermediate medium storage tank through an intermediate medium delivery pump. The intermediate heat transfer medium is at low temperature when pumped. After passing through at least two winding dual-channel convective heat exchange components, its temperature changes from low temperature to high temperature and then to low temperature back to the intermediate medium storage tank. It can not only effectively enhance the convective heat exchange of the double-tube heat exchange unit, but also has a simple structure, stable and reliable, and can achieve efficient sludge-sludge heat exchange.

[0003] However, due to the lack of corresponding auxiliary guiding structures during use, the heat exchange device is currently unable to separately guide the high-temperature heat transfer oil and the low-temperature heat transfer oil, thereby reducing the heat exchange efficiency of the heat exchange device. At the same time, during the flow of the high-temperature heat transfer oil, the heat absorption and conduction of the delivery pipeline causes uneven heat distribution inside the heat transfer oil, thereby reducing the heat exchange efficiency of the heat exchange device.

[0025] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0026] 1. An internal rotary circulation separation heat exchange mechanism is provided. Through the mutual cooperation between the components inside the internal rotary circulation separation heat exchange mechanism, the entire heat exchange process of the heat exchange device is optimized. The spiral auger is driven to cooperate with the stirring vertical plate to make the heat transfer oil inside the central separation tube rotate continuously during the flow process. During the rotation of the heat transfer oil, the heat transfer oil is separated and layered by centrifugal force with different temperature and density characteristics of the heat transfer oil, so that the heat transfer oil of the synchronous temperature can continue to flow in an independent path inside the central separation tube, and the flow path of the coolant is guided by the middle partition tube, the diversion end groove and the reflux middle groove, ensuring that the coolant will first exchange heat with the low-temperature heat transfer oil during the use of the heat exchange device, and then continue to exchange heat with the high-temperature heat transfer oil after the temperature of the coolant rises after the heat exchange, ensuring that the temperature difference of the heat exchange device will not be too large during the use of the heat exchange, effectively preventing the internal components of the heat exchange device from rapid fatigue aging due to long-term use in an environment with excessive temperature difference, thereby effectively improving the service life of the heat exchange device;

[0027] In addition, by driving the spiral auger, driving the internal gear ring, the gears in the transmission and the rotating gear ring, the power generated during the flow of the heat transfer oil is fully utilized to drive the various components inside the central separation tube to cooperate with each other, ensuring the rotation of the stirring vertical plate and the continuous rotation, separation and stratification of the heat transfer oil inside the central separation tube. The heat transfer oil is guided by the cooperation of the drainage outer capillary, the diversion outer capillary, the diversion inner capillary and the reflux inner capillary, which effectively improves the flow path of the heat transfer oil inside the central separation tube, extends the flow path of the heat transfer oil inside the central separation tube, and effectively increases the contact area between the heat transfer oil and the coolant, thereby effectively improving the heat exchange efficiency of the heat exchange device and optimizing the ease of use of the heat exchange device.

[0028] 2. An external telescopic flexible buffer mechanism is provided. Through the mutual cooperation between the components inside the external telescopic flexible buffer mechanism, the protection process of the heat exchange device during use is optimized. The outer side of the heat exchanger body is isolated and protected by the installation square box, the filling side box and the filling corner block to prevent the external impact from directly acting on the heat exchanger body and causing damage to its internal components, thereby ensuring the safety of the heat exchanger. The inside of the installation square box is filled and positioned by the filling side box and the filling corner block to prevent the heat exchanger body from shaking randomly along the inside of the installation square box during use, thereby further improving the safety of the heat exchanger.

[0029] At the same time, by squeezing the extrusion liquid bag during the vibration of the heat exchanger body, the transmission fluid inside the extrusion liquid bag can be alternately introduced into the interior of the mounting barrel through the liquid guide top pipe, and then the flow of the transmission fluid drives the components inside the mounting barrel to flow synchronously, and then the lifting and lowering of the lifting rack drives the vibration pinion and the vibration cam to rotate and vibrate, and then the vibration of the heat exchanger body during operation is buffered and offset by multiple groups of micro-vibrations of the vibration pinion and the vibration cam, so as to actively improve the internal stability of the heat exchange device, and through the mutual cooperation between the balance spring, the lifting spring and the support spring, the components inside the mounting barrel are auxiliary supported and balanced, ensuring that the transmission oil can also drive the components inside the mounting barrel to move when a small amount of flow occurs, thereby ensuring the smoothness of the operation of the components outside the heat exchanger, and further improving the stability and safety of the heat exchanger.

[0030] In summary, the use process of the heat exchange device is optimized through the mutual cooperation between the internal rotary circulation separation heat exchange mechanism and the external telescopic flexible buffer mechanism. By separating and layering the heat transfer oil inside the heat exchanger body, the heat exchanger will not have a large temperature difference at the contact point between the heat transfer oil and the coolant during the heat exchange process, thereby effectively preventing the heat exchanger from damaging the internal components of the heat exchanger body due to the large temperature difference during use. At the same time, through the mutual cooperation between the internal components of the filling side box and the filling corner block, the heat exchanger body is effectively avoided from being damaged by high-frequency vibration and collision during use, thereby effectively improving the safety and service life of the heat exchanger.

[0061] Narrow mounting plates 716 are fixedly mounted on both sides of the corresponding lifting rack 712 inside the mounting barrel 706, and vibration pinions 717 are rotatably mounted on both sides of the corresponding lifting rack 712 between the two narrow mounting plates 716, and vibration cams 718 are fixedly connected on both sides of the vibration pinion 717, and the outer side of the vibration pinion 717 is meshed with the side of the lifting rack 712, and the major diameter of the vibration cam 718 is smaller than the radius of the vibration pinion 717, and the mutual cooperation between the internal components of the external telescopic flexible buffer mechanism 7 is optimized. The heat exchange device is protected during use. The outer side of the heat exchanger body 1 is isolated and protected by installing the square box 701, the filling side box 702 and the filling corner block 703 to prevent the external impact from directly acting on the heat exchanger body 1 and causing damage to its internal components, thereby ensuring the safety of the heat exchange device. The inside of the installation square box 701 is filled and positioned by the filling side box 702 and the filling corner block 703 to prevent the heat exchanger body 1 from shaking randomly along the inside of the installation square box 701 during use, thereby further improving the safety of the heat exchange device.

[0062] At the same time, the extrusion liquid capsule 704 is squeezed during the vibration of the heat exchanger body 1, so that the transmission fluid inside the extrusion liquid capsule 704 can be alternately introduced into the installation barrel 706 through the liquid guide top pipe 705, and then the flow of the transmission fluid drives the components inside the installation barrel 706 to flow synchronously, and then the lifting and lowering of the lifting rack 712 drives the vibration pinion 717 and the vibration cam 718 to rotate and vibrate, and then the vibration of the heat exchanger body 1 during operation is buffered and offset by multiple groups of micro-vibrations of the vibration pinion 717 and the vibration cam 718, so as to actively improve the stability inside the heat exchange device, and through the mutual cooperation between the balance spring 708, the lifting spring 710 and the support spring 715, the components inside the installation barrel 706 are auxiliary supported and balanced, ensuring that the transmission oil can also drive the components inside the installation barrel 706 to move when a small amount of flow occurs, thereby ensuring the smoothness of the operation of the components outside the heat exchange device, and further improving the stability and safety of the heat exchange device.

[0063] Working principle and use process of the present invention: In the process of using the heat exchange device of the present invention, the heat exchange device needs to be installed to a suitable position first, the bottom liquid inlet pipe 2 is connected to the end of the discharge pipe of the high-temperature heat transfer oil, and the top liquid outlet pipe 3 is connected to the end of the liquid inlet pipe of the high-temperature heat transfer oil, and then the side liquid inlet pipe 4 is connected to the end of the liquid outlet pipe of the external coolant, and the side liquid outlet pipe 5 is connected to the end of the liquid inlet pipe of the external coolant, thereby completing the installation of the heat exchange device;

[0064] During the formal heat exchange process, the external high-temperature heat transfer oil is introduced into the heat exchanger body 1 through the bottom liquid inlet pipe 2, and when the heat transfer oil flows through the bottom driving tube 602, the driving spiral auger 603 at the bottom of the central mounting frame 604 is driven to rotate by the flow of the heat transfer oil, and in the process of driving the spiral auger 603 to rotate, the mounting side frame 605 and the driving inner gear ring 606 are synchronously driven to rotate, and in the process of driving the inner gear ring 606 to rotate, multiple transmission gears 607 are synchronously driven to rotate synchronously, and then the rotation of the transmission gear 607 drives the rotating gear ring 608 to rotate, and in the process of rotating the rotating gear ring 608, the rotating inner ring 609 and the stirring vertical plate 610 are synchronously rotated, and then the rotation of the stirring vertical plate 610 causes the heat transfer oil entering the central separation tube 601 to rotate at a high speed along the central axis of the central separation tube 601. During the process, due to the different densities of heat transfer oils at different temperatures, the heat transfer oil with a lower temperature will be concentrated on the edge of the inner cavity of the central separation tube 601 under the action of centrifugal force, while the heat transfer oil with a higher temperature will be concentrated in the outer area of ​​the central liquid guide tube 612, so that the heat transfer oil will be separated and layered inside and outside according to the temperature of the heat transfer oil under the action of centrifugal force during the process of rising inside the central separation tube 601, and then when the high-temperature heat transfer oil is continuously introduced into the bottom liquid inlet pipe 2, the heat transfer oil with a higher temperature will enter the top liquid separation box 611 through the liquid guide slot hole outside the central liquid guide tube 612, and then the high-temperature heat transfer oil will be introduced into the drainage outer capillary 613 through the top liquid separation box 611, and the high-temperature heat transfer oil in the drainage outer capillary 613 will be introduced into the guide outer capillary 616 through the drainage outer bottom box 614 and the reflux outer bottom box 615, and the high-temperature heat transfer oil after heat exchange will be introduced into the upper chamber of the heat exchanger body 1 through the liquid guide arc top box 617;

[0065] While the high-temperature heat-conducting oil flows along the inner part of the drainage outer capillary 613 and the flow-guiding outer capillary 616, the low-temperature heat-conducting oil can enter the inner part of the diverting inner arc cover 621 through the drainage slot hole on the side of the central separation tube 601, and then the low-temperature heat-conducting oil is introduced into the inner part of the diverting inner arc box 623 through the diverting inner capillary 622, and the low-temperature heat-conducting oil is introduced into the inner part of the return inner capillary 625 through the cooperation between the diverting inner arc box 623 and the return inner arc box 624, and the low-temperature heat-conducting oil in the return inner capillary 625 is introduced into the upper cavity of the heat exchanger body 1 through the return special-shaped top box 626, so that the heat-conducting oil that has completed heat exchange is discharged from the heat exchanger body 1 through the top liquid outlet pipe 3;

[0066] While the heat transfer oil flows through the interior of the heat exchanger body 1, the coolant is uniformly introduced into the interior of the heat exchanger body 1 through the side liquid inlet pipe 4. Since the middle chamber of the heat exchanger body 1 is divided into two inner and outer annular cavities by the middle partition tube 618, the coolant is directly introduced into the low-temperature heat transfer oil flow area inside the middle partition tube 618 through the side liquid inlet pipe 4 for heat exchange, and then the coolant is introduced into the high-temperature heat transfer oil heat exchange area outside the middle partition tube 618 through the diversion end groove 619 for heat exchange, and the coolant that has completed the heat exchange is guided to the end of the side liquid outlet pipe 5 through the reflux middle groove 620, so that the coolant flows out of the heat exchanger body 1 through the side liquid outlet pipe 5, and then the entire heat exchange process is realized by the synchronous staggered flow of the heat transfer oil and the coolant through the interior of the heat exchanger body 1;

[0067] When the heat exchange device is used for heat exchange, the outside of the heat exchanger body 1 needs to be protected. Each component is installed on the outside of the heat exchanger body 1 through the installation box 701, and then the inner cavity of the installation box 701 is separated by the filling side box 702 and the filling corner block 703. When the installation box 701 shakes during operation, the filling side box 702 and the squeezing liquid capsule 704 are squeezed, and after the squeezing liquid capsule 704 is squeezed, the transmission fluid inside the squeezing liquid capsule 704 is introduced into the installation barrel 706 through the liquid guide top pipe 705.

[0068] After the transmission fluid enters the installation barrel 706, the hydraulic pressure of the uppermost cavity of the installation barrel 706 will rise, and then the transmission fluid squeezes the partition slide 709 to balance the elastic force of the spring 708 and slide downward along the installation box 707. In the process of the partition slide 709 sliding downward, the transmission oil inside the installation box 707 squeezes the telescopic slide bar 711 downward, so that the telescopic slide bar 711 overcomes the elastic force of the lifting spring 710 and the support spring 715 and slides downward, and the lifting rack 7 is adjusted by the sliding cooperation between the guide bottom tube 713 and the limit bottom tube 714. 12 is guided during the lifting and sliding process to ensure that the lifting rack 712 will not deviate during the vertical sliding process, and the vibration pinion 717 on the side of the installation narrow plate 716 is driven to rotate during the lifting and sliding process of the lifting rack 712, and the vibration cam 718 is driven to rotate during the rotation of the vibration pinion 717, and the installation barrel 706 is driven to vibrate through the rotation of the vibration cam 718, and the vibration generated during the movement of the heat exchanger body 1 is offset by the vibration balance of the installation barrel 706, so as to ensure the stability of the operation of the heat exchange device;
