Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat energy engineering and high-efficiency energy-saving equipment, in particular to a bionic heat exchanger based on seal whisker disturbance and wheat grain communication configuration. BACKGROUND

[0002] As a key thermal management device indispensable in many fields such as energy chemical industry, aerospace, electronic cooling and waste heat recovery, the heat transfer efficiency of the heat exchanger directly determines the system energy utilization rate and operating cost, and plays a core role in energy saving and emission reduction and efficient operation of equipment. The traditional heat exchanger widely used in the current industrial field is mainly tube-shell type and column type. The core heat exchange unit of this type of heat exchanger is a flat pipe. When the fluid flows in the pipe, a stable laminar boundary layer is easily formed near the pipe wall due to viscous action. This laminar boundary layer, as the main thermal resistance, seriously hinders the heat transfer from the fluid core to the pipe wall, resulting in limited overall heat transfer efficiency. To break this bottleneck, various improvement schemes for strengthening heat transfer have appeared in the prior art. One is to insert a disturbance member such as a twisted tape or a spiral coil into the pipe to destroy the laminar boundary layer and enhance the intensity of turbulent flow to improve heat transfer effect. However, this traditional disturbance structure not only strengthens turbulent flow, but also significantly increases fluid flow resistance, resulting in a significant increase in pumping power consumption and energy waste. The second is to install solid fins outside the pipe to expand the heat exchange area and enhance heat transfer. However, solid fins cannot change the state of mutual isolation of the fluid between the pipes. The fluid can only flow in the axial direction, making it difficult to achieve lateral mass exchange and thermal mixing between the pipe bundles, and easily forming local heat accumulation and flow dead zones between the pipes, which not only affects the uniformity of heat exchange, but also causes dust accumulation and scaling due to structural dead angles, increasing equipment maintenance difficulty and cost.

[0003] In addition, although some improvement schemes attempt to balance heat transfer efficiency and flow resistance, they often have problems such as complex structure, difficult processing or limited adaptation scenarios, and cannot fundamentally solve the contradiction between heat transfer enhancement and low resistance operation, thus failing to meet the comprehensive demand for "high efficiency, low resistance, stability and easy maintenance" of the heat exchanger under high heat flux dissipation, waste heat recovery and other working conditions. Therefore, it is urgent to develop a new heat exchanger structure to break through the performance constraints of the prior art. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a bionic heat exchanger based on seal whisker disturbance and wheat grain communication configuration, which solves the problems raised in the background art.

[0005] To achieve the above purpose, the present application realizes the following technical scheme: a bionic heat exchanger based on seal whisker disturbance and wheat grain communication configuration, comprising an inlet manifold, an outlet manifold and a plurality of heat exchange pipes, the heat exchange pipes being arranged in a horizontal array, the inlet manifold being correspondingly arranged at one end of the heat exchange pipes, and the outlet manifold being correspondingly arranged at the other end of the heat exchange pipes.

[0006] Preferably, the device further includes an inlet tube sheet and an outlet tube sheet. The inlet tube sheet is fixedly installed on the side of the inlet manifold facing the heat exchange tube, and the outlet tube sheet is fixedly installed on the side of the outlet manifold facing the heat exchange tube. One end of the heat exchange tube is fixedly connected to the inlet tube sheet, and the other end of the heat exchange tube is fixedly connected to the outlet tube sheet.

[0007] Preferably, it further includes a fluid inlet and an inlet straight pipe, one end of which is fixedly connected to the fluid inlet, and the other end of which is fixedly connected to the inlet collecting cavity. The fluid inlet is located at the top of the inlet collecting cavity and is vertically upward.

[0008] Preferably, it further includes a fluid outlet and an outlet straight pipe, one end of which is fixedly connected to the fluid outlet, and the other end of which is fixedly connected to the outlet collecting cavity. The fluid outlet is located at the top of the outlet collecting cavity and is vertically upward.

[0009] Preferably, it also includes a plurality of seal whisker-like bristle-shaped bristle-shaped bristle-shaped columns, which are arranged in an axial array along the inner wall of the heat exchange tube. The bristle-like bristle-shaped bristle-shaped columns extend toward the center of the heat exchange tube. The cross-section of the bristle-like bristle-shaped columns is elliptical, and the elliptical cross-section undergoes periodic phase twisting along the height of the column to form a wave-like surface.

[0010] Preferably, the ratio of the height H of the seal whisker-like turbulence column to the inner radius R of the heat exchange tube is 0.3 to 0.5.

[0011] Preferably, the ratio of the height H of the seal whisker-like turbulence column to the inner radius R of the heat exchange tube is 0.4.

[0012] Preferably, it further includes a plurality of hollow imitation wheat grain connecting tubes, wherein the hollow imitation wheat grain connecting tubes are connected between two adjacent heat exchange tubes, wherein the hollow imitation wheat grain connecting tubes enable the internal flow channels of adjacent heat exchange tubes to communicate with each other, and the hollow imitation wheat grain connecting tubes are arranged in a staggered pattern among the tube bundles composed of heat exchange tubes.

[0013] Preferably, a smooth tube transition section is provided at the connection between both ends of the heat exchange tube and the inlet tube sheet and the outlet tube sheet. The surface of the smooth tube transition section has no biomimetic structure and remains smooth. The length of the smooth tube transition section is 10mm to 20mm.

[0014] Preferably, both the inlet manifold and the outlet manifold are large-volume rectangular box structures. The inlet manifold is fastened to the side of the inlet tube sheet away from the heat exchange tubes, and the outlet manifold is fastened to the side of the outlet tube sheet away from the heat exchange tubes.

[0015] This invention provides a biomimetic heat exchanger based on a seal whisker-like turbulence and a wheat grain-like interconnected configuration. It possesses the following beneficial effects: 1. This invention induces hairpin vortex generation through the wave-shaped torsion structure of the seal whisker-like turbulence column inside the tube, which efficiently destroys the thermal boundary layer and promotes heat exchange inside the fluid. At the same time, it constructs a three-dimensional networked flow channel by using hollow wheat grain-like connecting tubes between the tubes to achieve lateral fluid mixing between the tube bundles. The synergistic effect of the two structures completely eliminates local heat accumulation and flow dead zones, and significantly enhances the overall heat transfer performance.

[0016] 2. This invention effectively suppresses the periodic shedding of the Karman vortex street and reduces flow-induced vibration and form resistance by using a streamlined elliptical cross-section and periodic torsion design of a seal whisker-like flow-disrupting column. Combined with the hollow, grain-like connecting pipes arranged in a staggered pattern between the pipes, it avoids excessive obstruction of the flow channel when guiding the three-dimensional flow of the fluid. With the static pressure equalization design of the flow collection cavity, it achieves an optimized balance between efficient heat exchange and low flow resistance.

[0017] 3. This invention forms a truss-like support system between tube bundles by densely arranged hollow, grain-like connecting tubes, which significantly enhances the overall structural strength and pressure resistance of the heat exchanger core. The smooth tube transition sections at both ends of the heat exchange tubes solve the sealing connection problem between the irregular tubes and the tube sheet and alleviate welding stress. The top-inlet and top-outlet structure of the flow collection cavity realizes the natural exhaust function, avoiding the effects of air pockets and cavitation, making the overall structure compact and adaptable to various engineering application scenarios.

Detailed Implementation

[0020] The technical solutions in 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.

[0021] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a biomimetic heat exchanger based on the configuration of seal whisker turbulence and wheat grain connectivity, including an inlet collector cavity 3, an outlet collector cavity 9 and a plurality of heat exchange tubes 5. The heat exchange tubes 5 are arranged in a horizontal array, with the inlet collector cavity 3 correspondingly disposed at one end of the heat exchange tube 5 and the outlet collector cavity 9 correspondingly disposed at the other end of the heat exchange tube 5.

[0022] Specifically, by arranging several heat exchange tubes 5 in a horizontal array, a regular and dense heat exchange core area is formed. At the same time, the inlet manifold 3 and the outlet manifold 9 are respectively set at both ends of the heat exchange tubes 5, constructing a basic fluid flow path of inlet manifold - tube bundle heat exchange - outlet confluence. The inlet manifold 3 can buffer and evenly distribute the incoming working fluid, ensuring that the fluid can flow smoothly and evenly into the interior of each heat exchange tube 5 to participate in the heat exchange process. The outlet manifold 9 can collect and guide the fluid after heat exchange, so that the fluid is discharged in an orderly manner. Through this core structural layout, the foundation is laid for subsequent integration with the seal whisker-like turbulence column 6 to achieve enhanced heat exchange within the tube and for constructing three-dimensional flow between tubes with the help of the hollow grain-like connecting tube 7, ensuring the stability of fluid flow and the improvement of heat exchange efficiency during the heat exchange process.

[0023] It also includes an inlet tube sheet 4 and an outlet tube sheet 8. The inlet tube sheet 4 is fixedly installed on the side of the inlet manifold 3 facing the heat exchange tube 5, and the outlet tube sheet 8 is fixedly installed on the side of the outlet manifold 9 facing the heat exchange tube 5. One end of the heat exchange tube 5 is fixedly connected to the inlet tube sheet 4, and the other end of the heat exchange tube 5 is fixedly connected to the outlet tube sheet 8.

[0024] Specifically, by fixing the inlet tube sheet 4 to the side of the inlet manifold 3 facing the heat exchange tube 5 and the outlet tube sheet 8 to the side of the outlet manifold 9 facing the heat exchange tube 5, and fixing both ends of the heat exchange tube 5 to the inlet tube sheet 4 and the outlet tube sheet 8 respectively, on the one hand, the inlet tube sheet 4 and the outlet tube sheet 8 achieve a sealed connection between the inlet manifold 3, the outlet manifold 9 and the heat exchange tube 5, preventing fluid leakage during flow. On the other hand, the tube sheets position and support the horizontally arrayed heat exchange tubes 5, ensuring the regularity of the heat exchange tube layout and the structural stability of the heat exchange tubes 5. At the same time, they provide a precise flow channel for the fluid to be smoothly introduced into each heat exchange tube 5 from the inlet manifold 3 and then orderly merged into the outlet manifold 9 from each heat exchange tube 5, further improving the fluid path of collection-heat exchange-merging, and creating a reliable structural foundation for the synergistic effect of enhanced turbulence inside the tubes and three-dimensional flow between the tubes.

[0025] It also includes a fluid inlet 1 and an inlet straight pipe 2. One end of the inlet straight pipe 2 is fixedly connected to the fluid inlet 1, and the other end of the inlet straight pipe 2 is fixedly connected to the inlet manifold 3. The fluid inlet 1 is located at the top of the inlet manifold 3 and is vertically upward. It also includes a fluid outlet 10 and an outlet straight pipe 11. One end of the outlet straight pipe 11 is fixedly connected to the fluid outlet 10, and the other end of the outlet straight pipe 11 is fixedly connected to the outlet manifold 9. The fluid outlet 10 is located at the top of the outlet manifold 9 and is vertically upward.

[0026] Specifically, by fixing the two ends of the inlet straight pipe 2 to the fluid inlet 1 and the inlet manifold 3 respectively, and fixing the two ends of the outlet straight pipe 11 to the fluid outlet 10 and the outlet manifold 9 respectively, a complete flow channel for the fluid to enter and exit the heat exchanger is constructed. At the same time, the fluid inlet 1 and the fluid outlet 10 are both set at the top of the corresponding manifold and arranged vertically upwards. With the large volume structure of the manifold, the fluid can be guided smoothly into and out of the manifold by the inlet straight pipe 2 and the outlet straight pipe 11, avoiding the flow turbulence caused by fluid impact. It can also use buoyancy to achieve natural exhaust, effectively expelling the gas entrained in the fluid, preventing the formation of air pockets and cavitation from interfering with the heat exchange process. At the same time, it ensures the stability of the fluid static pressure in the inlet manifold 3, providing a guarantee for the uniform distribution of fluid to each heat exchange tube 5. It also allows the fluid that has completed heat exchange in the outlet manifold 9 to flow out in an orderly manner. This further optimizes the stability of the fluid flow throughout the entire process of inlet-manifold-heat exchange-manifold-outlet, providing support for improving heat exchange efficiency.

[0027] It also includes several seal whisker-shaped baffle columns 6, which are axially arrayed along the inner wall of the heat exchange tube 5. The seal whisker-shaped baffle columns 6 extend towards the center of the heat exchange tube 5. The cross-section of the seal whisker-shaped baffle columns 6 is elliptical, and the elliptical cross-section undergoes periodic phase torsion along the height of the column to form a wave-like surface.

[0028] Specifically, by arranging several seal whisker-like flow-disrupting columns 6 extending towards the center along the axial direction on the inner wall of the heat exchange tube 5, and using an elliptical cross-section with periodic phase twisting along the height of the column to form a wave-like surface, the biomimetic structure induces hairpin vortices when the fluid flows through the heat exchange tube 5, effectively disrupting the thermal boundary layer near the tube wall and promoting heat exchange between the fluid core region and the near-wall region. At the same time, the synergistic effect of the streamlined elliptical cross-section and the wave-like surface suppresses the periodic shedding of the Karman vortex street, reduces flow-induced vibration and flow resistance, and enhances the convective heat transfer effect inside the tube without increasing excessive energy consumption, providing a core tube-in-tube enhancement mechanism for improving the overall heat exchange efficiency of the heat exchanger.

[0029] The ratio of the height H of the seal whisker-like baffle column 6 to the inner radius R of the heat exchange tube 5 is 0.3 to 0.5. The ratio of the height H of the seal whisker-like baffle column 6 to the inner radius R of the heat exchange tube 5 is 0.4.

[0030] Specifically, by setting the ratio of the height H of the seal whisker-like turbulence column 6 to the inner radius R of the heat exchange tube 5 to 0.3 to 0.5, with a preferred ratio of 0.4, it ensures that the seal whisker-like turbulence column 6 can effectively penetrate the thermal boundary layer near the tube wall of the heat exchange tube 5 and reach deep into the mainstream fluid region, fully leveraging the enhanced heat transfer effect of inducing eddies and disrupting the thermal boundary layer. At the same time, it can retain a sufficient straight flow channel in the center of the heat exchange tube 5, avoiding excessive narrowing of the flow channel and resulting in a surge in flow resistance. This achieves a precise balance between enhanced heat transfer effect and flow resistance control within the tube, ensuring that the heat exchanger maintains low pumping power consumption while achieving efficient heat transfer, and further optimizing the overall heat transfer performance.

[0031] It also includes several hollow imitation wheat grain connecting pipes 7, which are connected between two adjacent heat exchange tubes 5. The hollow imitation wheat grain connecting pipes 7 enable the internal flow channels of adjacent heat exchange tubes 5 to communicate with each other. The hollow imitation wheat grain connecting pipes 7 are arranged in a staggered pattern between the tube bundles composed of heat exchange tubes 5.

[0032] Specifically, by connecting several hollow, grain-like connecting pipes 7 between two adjacent heat exchange tubes 5, the internal flow channels of adjacent heat exchange tubes 5 are interconnected. The hollow, grain-like connecting pipes 7 are arranged in a staggered pattern between the tube bundles composed of heat exchange tubes 5. On the one hand, this breaks the traditional state of fluid isolation between heat exchanger tubes, constructs a transverse fluid channel between tubes, and enables the fluid to form a three-dimensional networked flow pattern of "axial flow + transverse flow". This strengthens the turbulent mixing and heat exchange between tube bundles, and completely eliminates local heat accumulation and flow dead zones. On the other hand, the staggered arrangement causes the fluid flow path to change continuously, further enhancing fluid disturbance. While improving the heat exchange uniformity between tubes and the overall heat exchange effect, the synergistic effect of the hollow structure and staggered layout avoids excessive obstruction to fluid flow, maintains low flow resistance, and works in synergy with the enhanced heat exchange mechanism of the seal whisker-like turbulence columns 6 inside the tubes to jointly improve the comprehensive heat exchange performance of the heat exchanger.

[0033] At the connection points between the heat exchange tube 5 and the inlet tube sheet 4 and the outlet tube sheet 8, a smooth tube transition section is provided. The surface of the smooth tube transition section has no biomimetic structure and remains smooth. The length of the smooth tube transition section is 10mm to 20mm.

[0034] Specifically, by setting smooth, 10mm-20mm long smooth tube transition sections with no biomimetic structure at the connection points between the heat exchange tube 5 and the inlet tube sheet 4 and outlet tube sheet 8, the smooth surface reduces the welding difficulty at the connection points between the tube sheet and the heat exchange tube 5, ensuring the reliability of the sealed connection. At the same time, the transition section can alleviate the stress concentration generated during the welding process, avoiding insufficient connection strength or stress cracking caused by the presence of biomimetic structures. It also provides a smooth transition flow channel for the fluid to enter and exit the heat exchange tube 5, reducing abrupt changes in fluid flow and resistance loss at the connection points, ensuring the continuity and stability of fluid flow, and providing support for the synergistic optimization of the heat exchanger's structural safety and heat exchange efficiency.

[0035] Both the inlet manifold 3 and the outlet manifold 9 are large-volume rectangular box structures. The inlet manifold 3 is fastened to the side of the inlet tube sheet 4 away from the heat exchange tube 5, and the outlet manifold 9 is fastened to the side of the outlet tube sheet 8 away from the heat exchange tube 5.

[0036] Specifically, by designing the inlet manifold 3 and outlet manifold 9 as large-volume rectangular box structures, and fastening them to the side of the inlet tube sheet 4 and outlet tube sheet 8 away from the heat exchange tubes 5 respectively, the large-volume cavities provide ample buffer space for the fluid, enabling the fluid entering the inlet manifold 3 to establish a stable static pressure and achieve uniform distribution to each heat exchange tube 5. At the same time, the outlet manifold 9 can smoothly collect the fluid discharged from each heat exchange tube 5, avoiding flow turbulence caused by sudden changes in local flow velocity. On the other hand, the fastening installation ensures the sealing of the connection between the manifold and the tube sheet, preventing fluid leakage. Furthermore, the rectangular box structure is compatible with the horizontal array layout of the tube sheet and heat exchange tubes 5, maximizing space utilization and providing a structural basis for natural exhaust and fluid equalization of the top-inlet and top-outlet structure, further ensuring the overall flow field stability of the heat exchanger and the efficient and orderly operation of the heat exchange process.

[0037] Working Principle: The working fluid enters the inlet straight pipe 2 through the vertically upward-facing fluid inlet 1. After being guided by the inlet straight pipe 2, it flows into the inlet manifold 3. The inlet manifold 3 adopts a large-volume rectangular box structure, which enables the fluid to establish a stable static pressure within the cavity, achieving uniform fluid distribution. Simultaneously, the "top-in, top-out" structural design utilizes buoyancy to naturally expel entrained gases in the fluid, preventing air pocket formation and cavitation. After being uniformly distributed through the inlet manifold 3, the fluid enters the horizontally arrayed heat exchange tubes 5 through corresponding channels on the inlet tube sheet 4. During the flow of the fluid within the heat exchange tubes 5, it is affected by the seal whisker-like turbulence columns 6 axially arrayed on the inner wall of the tube. The elliptical cross-section and periodic phase torsion structure along the height of the columns 6 induce hairpin vortices in the fluid. These vortices efficiently disrupt the thermal boundary layer near the tube wall, promoting rapid heat exchange between the fluid core region and the near-wall region, while simultaneously suppressing the periodic shedding of the Karman vortex street, reducing flow resistance and flow-induced vibration. Meanwhile, some fluid flows laterally through hollow grain-like connecting pipes 7 connected between adjacent heat exchange tubes 5. The staggered arrangement of the hollow grain-like connecting pipes 7 between the tube bundles creates a "Z"-shaped or wavy flow path for the fluid between the tubes, continuously changing the fluid direction, enhancing turbulent mixing and mass exchange between the tube bundles, completely eliminating local heat accumulation and flow dead zones, and forming a three-dimensional networked composite flow mode of "axial flow + lateral flow", which greatly improves the overall heat exchange effect. The fluid that has completed the heat exchange process is collected by the outlet tube sheet 8 and flows to the outlet manifold 9. The outlet manifold 9 also has the functions of large-volume static pressure equalization and natural venting. Finally, the fluid is discharged from the vertically upward fluid outlet 10 through the outlet straight pipe 11, completing the entire heat exchange cycle.
