Description

Technical Field

[0001] This utility model belongs to the field of heat exchange equipment, specifically relating to a turbulence structure for plate heat exchangers. Background Technology

[0002] Plate heat exchangers, as highly efficient heat exchange devices, are widely used in industries such as chemical, petroleum, food, and pharmaceutical. Their core component is the heat exchange plate, through which heat is transferred via the flow of the medium between the plates. To improve heat exchange efficiency, turbulence structures are typically incorporated into the heat exchange plates to increase the degree of turbulence in the medium, thereby enhancing the heat exchange effect.

[0003] However, traditional turbulence structures have several shortcomings. First, their turbulence effect is limited, failing to adequately disrupt the laminar flow of the medium, resulting in only a slight improvement in heat exchange efficiency. This is because traditional turbulence structures are relatively simple in design and cannot effectively change the flow direction and velocity of the medium, thus failing to fully utilize the surface area of ​​the heat exchanger. Second, the strength of turbulence structures is low, making them prone to deformation or damage after long-term use, affecting the service life of the heat exchanger. This is mainly due to the inadequate material selection and structural design of traditional turbulence structures, which cannot withstand long-term high-temperature, high-pressure, and corrosive environments. Furthermore, traditional turbulence structures are prone to fouling, making cleaning difficult and increasing maintenance costs and workload. Fouling not only reduces heat exchange efficiency but can also lead to equipment corrosion, shortening its service life.

[0004] To address these issues, the industry has been seeking new turbulence-inducing structural designs. An ideal turbulence-inducing structure should significantly increase the turbulence effect while enhancing structural strength and facilitating the cleaning of scale buildup. Specifically, new turbulence-inducing structures need to meet the following requirements: First, they must effectively increase the turbulence of the medium, breaking the laminar flow state and fully utilizing the surface area of ​​the heat exchange plates; second, they must possess sufficient structural strength to withstand long-term high temperatures, high pressures, and corrosive environments; and finally, they must have good self-cleaning capabilities, reducing scale buildup and facilitating maintenance and cleaning.

[0005] However, designing such a flow-disrupting structure is no easy task. A balance must be struck between the flow-disrupting effect, structural strength, and ease of cleaning. For example, increasing the flow-disrupting effect may lead to a decrease in structural strength; while increasing structural strength may affect ease of cleaning. Therefore, innovative design concepts and meticulous engineering calculations are required to develop a novel flow-disrupting structure that meets these requirements. Utility Model Content

[0006] This invention provides a turbulence-disrupting structure for plate heat exchangers to solve at least one of the aforementioned technical problems.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A turbulence-inducing structure for a plate heat exchanger, the technical solution of which is as follows: includes a heat exchange plate, wherein both sides of the heat exchange plate are provided with flow guiding cavities for medium flow, and a plurality of sets of turbulence-inducing flanges are arranged at intervals along the medium flow direction in the flow guiding cavities, and a turbulence-inducing channel is formed between adjacent turbulence-inducing flanges, wherein the height of the turbulence-inducing flange is less than the depth of the tank, and the cross-section of the turbulence-inducing flange is trapezoidal.

[0009] Preferably, the turbulence flange has a symmetrical V-shaped structure.

[0010] Preferably, the adjacent turbulence flanges are respectively provided with a first turbulence port and a second turbulence port for connecting adjacent turbulence channels.

[0011] Preferably, both the first and second turbulence ports are provided with at least two at intervals.

[0012] Preferably, the first and second turbulence ports are diagonally distributed.

[0013] Preferably, the cross-sectional widths of the first and second turbulence ports along the medium flow direction first decrease and then increase.

[0014] Preferably, it also includes an inlet and an outlet for connecting the flow channel.

[0015] Preferably, the heat exchange plate is provided with a sealing ring.

[0016] Preferably, multiple sets of heat exchange plates are stacked so that the turbulence channels on adjacent end faces are connected to form a turbulence chamber, and the cross-sectional area of ​​the turbulence chamber along the medium flow direction first increases and then decreases.

[0017] Preferably, the heat exchange plate is made of one or more of stainless steel, titanium alloy, nickel alloy, and aluminum alloy.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0019] 1. The heat exchange plate has flow-guiding cavities on both sides, allowing for more efficient medium flow. Secondly, the trapezoidal cross-section of the turbulence-inducing flange generates a turbulence effect during flow. This design increases turbulence as the medium flows through the flow-guiding cavities, improving heat exchange efficiency. Furthermore, the height of the turbulence-inducing flange is designed to be less than the depth of the flow-guiding cavities, ensuring structural stability and strength. Optimizing the shape and layout of the turbulence-inducing flange significantly enhances the turbulence effect, and the materials and structural design improve overall strength and durability. In addition, the optimized design also alleviates fouling issues, reducing maintenance workload.

[0020] Specifically, the trapezoidal cross-section design and height control of the turbulence flange generate stronger turbulence as the medium flows through it, thereby improving heat exchange efficiency. This design also enhances the structural strength and durability while reducing fouling. Overall, this technical solution improves heat exchange efficiency, reduces maintenance costs, and extends the service life of the plate heat exchanger.

[0021] 2. By designing a symmetrical V-shaped turbulence flange, the aim is to further optimize the turbulence effect. The V-shaped structure can better guide the flow of the medium, break the laminar flow state, increase the degree of turbulence, and thus improve heat exchange efficiency. This structural design can also enhance the mechanical strength of the turbulence flange, reduce the risk of deformation, and extend its service life.

[0022] 3. By setting a first turbulence port and a second turbulence port on adjacent turbulence flanges, the connection between adjacent turbulence channels is achieved, effectively enhancing the turbulence effect of the medium and increasing the complexity of the flow path, thereby improving heat exchange efficiency. Specifically, the setting of the first and second turbulence ports allows the medium to flow alternately between different channels when flowing through the turbulence channels, breaking the laminar flow state of the medium and increasing the degree of turbulence. By setting multiple turbulence ports on adjacent turbulence flanges, the degree of turbulence of the fluid medium in the turbulence channels can be enhanced, thereby improving heat exchange efficiency. The spacing of these turbulence ports not only helps to improve the uniformity of fluid flow but also effectively reduces flow resistance, thereby improving the overall performance of the heat exchanger.

[0023] Furthermore, the first and second turbulence inlets are diagonally distributed to further enhance the turbulence effect by adjusting the fluid flow path. This design not only optimizes the fluid flow direction but also effectively reduces local fluid stagnation and avoids non-uniformity of flow velocity, thereby improving the overall turbulence performance and enhancing heat exchange efficiency.

[0024] 4. The cross-sectional widths of the first and second turbulence orifices decrease and then increase along the direction of medium flow. This design helps to further enhance the turbulence effect. Through this structure, the medium undergoes a cross-sectional change as it flows through the turbulence orifices, thereby increasing the complexity and turbulence of the flow and thus improving heat exchange efficiency. Furthermore, this cross-sectional change design helps prevent fouling at the turbulence orifices, facilitating subsequent cleaning and maintenance. Attached Figure Description

[0038] Reference Figures 1-5 A turbulence-dissipating structure for plate heat exchangers is of great significance in the field of heat exchange technology. Plate heat exchangers, as highly efficient heat exchange devices, are widely used in various industries. Their core component is the heat exchange plate 1, which transfers heat through the flow of the medium. However, traditional turbulence-dissipating structures suffer from limited turbulence effects, insufficient structural strength, and susceptibility to fouling. These problems result in limited improvement in heat exchange efficiency and increased maintenance costs. The solution proposed in this application significantly improves these shortcomings through optimized design.

[0039] Those skilled in the art will understand that in plate heat exchangers, the laminar flow state of the medium limits the improvement of heat exchange efficiency. To overcome this limitation, enhancing the degree of turbulence is crucial. By considering how to improve the turbulence effect without increasing structural complexity, this application proposes a novel turbulence structure design. The core of this design lies in the fact that both sides of the heat exchange plate 1 are provided with flow guiding cavities, and several sets of turbulence flanges 3 are spaced apart within the cavities along the medium flow direction. Through this design, the path of medium flow is optimized, thereby improving heat exchange efficiency.

[0040] The heat exchange plate 1 is a key component for heat transfer, with the flow guiding cavity and the turbulence-inducing flange 3 being the main elements of this design. The flow guiding cavity serves as a channel for the medium flow, while the turbulence-inducing flange 3 is used to break the laminar flow and increase the degree of turbulence. Specifically, the cross-section of the turbulence-inducing flange 3 is trapezoidal, and its height is less than the depth of the flow guiding cavity. This design can form an effective turbulence-inducing channel 2 between adjacent turbulence-inducing flanges 3. In addition, the choice of materials such as stainless steel and titanium alloy for the turbulence-inducing flange 3 ensures the strength and durability of the structure.

[0041] The turbulence-inducing structure of this application achieves efficient heat exchange through a series of design features. First, the heat exchange plate 1 has flow-guiding cavities on both sides, allowing the medium to flow more effectively. Second, the cross-section of the turbulence-inducing flange 3 is trapezoidal, which generates a turbulence effect during flow. Through this design, the turbulence level increases as the medium flows through the flow-guiding cavities, thereby improving heat exchange efficiency. In addition, the height of the turbulence-inducing flange 3 is designed to be less than the depth of the flow-guiding cavities, ensuring the stability and strength of the structure.

[0042] Compared with traditional technologies, the turbulence structure in this application has advantages in several aspects. Traditional turbulence structures are usually difficult to effectively break laminar flow and are prone to fouling, increasing maintenance difficulty. The design in this application, by optimizing the shape and layout of the turbulence flange 3, significantly enhances the turbulence effect, and the materials and structural design used improve overall strength and durability. Furthermore, the optimized design also alleviates the fouling problem, reducing maintenance workload.

[0043] The technical solution of this application effectively solves the shortcomings of traditional turbulence structures by setting a flow guiding cavity and a turbulence-inducing flange 3 on the heat exchange plate 1. The trapezoidal cross-section design and height control of the turbulence-inducing flange 3 generate a stronger turbulence effect when the medium flows through it, thereby improving heat exchange efficiency. Through this design, the strength and durability of the structure are enhanced, while reducing the formation of fouling deposits. Overall, this technical solution improves heat exchange efficiency, reduces maintenance costs, and extends the service life of the plate heat exchanger.

[0044] As a preferred example of the turbulence flange 3, refer to Figures 1-3 The turbulence flange 3 has a symmetrical V-shaped structure.

[0045] This application aims to further optimize the turbulence effect by designing a symmetrical V-shaped turbulence flange 3. The V-shaped structure can better guide the flow of the medium, break the laminar flow state, increase the degree of turbulence, and thus improve the heat exchange efficiency. This structural design can also enhance the mechanical strength of the turbulence flange 3, reduce the risk of deformation, and extend its service life.

[0046] Specifically, the symmetrical V-shaped spoiler flange 3 can be achieved through different manufacturing processes, such as stamping or casting. The angle and dimensions of the V-shape can be adjusted according to specific application requirements to achieve optimal spoilage effect and structural strength. As a preferred embodiment, the angle of the V-shaped spoiler flange 3 can be set between 30 and 60 degrees to ensure optimal turbulence effect and strength balance.

[0047] Therefore, by adopting a symmetrical V-shaped turbulence flange 3 design, this application further enhances the turbulence effect of the medium, improves the heat exchange efficiency, and also enhances the structural strength and extends the service life of the heat exchanger compared to the traditional turbulence structure.

[0048] As a preferred embodiment of this application, refer to Figures 1-3 The adjacent turbulence flanges 3 are respectively provided with a first turbulence port 4 and a second turbulence port 5 for connecting the adjacent turbulence channels 2.

[0049] By setting a first turbulence port 4 and a second turbulence port 5 on adjacent turbulence flanges 3, the connection between adjacent turbulence channels 2 is achieved. This design can effectively enhance the turbulence effect of the medium, increase the complexity of the flow path, and thus improve the heat exchange efficiency. Specifically, the setting of the first turbulence port 4 and the second turbulence port 5 allows the medium to flow alternately between different channels when flowing through the turbulence channels 2, breaking the laminar flow state of the medium and increasing the degree of turbulence.

[0050] Various structures can be used to implement the first and second flow deflectors 4 and 5. For example, the flow deflectors can be designed as circular, elliptical, or other suitable geometries to adapt to different fluid characteristics and flow requirements. Furthermore, the location and number of flow deflectors can be adjusted according to specific application needs to optimize the flow deflection effect and flow resistance.

[0051] By providing a first turbulence port 4 and a second turbulence port 5 on adjacent turbulence flanges 3, this application significantly improves the turbulence effect of the plate heat exchanger. This structure not only increases the flow path and turbulence level of the medium but also effectively improves the heat exchange efficiency. Furthermore, this design reduces medium deposition on the surface of the heat exchange plate 1, lowers the difficulty of cleaning and maintenance, and thus extends the service life of the heat exchanger.

[0052] Furthermore, at least two of each of the first and second turbulence ports 4 and 5 are spaced apart. By providing multiple turbulence ports on adjacent turbulence flanges 3, the turbulence of the fluid medium within the turbulence channel 2 can be enhanced, thereby improving heat exchange efficiency. The spacing of these turbulence ports not only helps improve the uniformity of fluid flow but also effectively reduces flow resistance, thus improving the overall performance of the heat exchanger.

[0053] The spacing between the first turbulence port 4 and the second turbulence port 5 can be achieved in various ways. For example, they can be evenly distributed, ensuring that the distance between each turbulence port is equal, thus guaranteeing a smoother and more uniform fluid flow within the channel. Alternatively, as a preferred embodiment, they can be designed with an irregular distribution to adapt to different application scenarios, based on specific fluid characteristics and heat exchange requirements. Furthermore, the size and shape of these turbulence ports can be adjusted according to actual needs to further optimize the fluid turbulence effect.

[0054] In summary, this application significantly improves the turbulence effect of the plate heat exchanger by setting multiple turbulence ports at intervals on the turbulence flange 3. This not only improves the heat exchange efficiency but also enhances the adaptability and flexibility of the structure, helping to meet diverse application needs.

[0055] Furthermore, the first spoiler 4 and the second spoiler 5 are diagonally distributed.

[0056] The technical solution of this application mainly enhances the turbulence effect by optimizing the arrangement of the turbulence inlets. Specifically, the first turbulence inlet 4 and the second turbulence inlet 5 are diagonally distributed, aiming to adjust the flow path of the fluid. This design not only optimizes the flow direction of the fluid but also effectively reduces local fluid stagnation and avoids non-uniformity of flow velocity, thereby improving the overall turbulence performance and enhancing the heat exchange effect.

[0057] The first and second turbulence ports 4 and 5 can be formed through precise machining of the heat exchange plate 1 using precision molds or stamping techniques to ensure accurate control of the size, position, and distribution angle of the turbulence ports. Furthermore, this arrangement can enhance the corrosion resistance and strength of the heat exchange plate 1 by selecting different materials and thicknesses, ensuring its stability during long-term use.

[0058] By designing the diagonal distribution of the turbulence inlets, the problem of fluid stagnation in the turbulence structure of traditional heat exchangers can be effectively solved, improving heat exchange efficiency and structurally enhancing the strength and service life of the plate heat exchanger. This solution not only improves the medium flow state but also contributes to the long-term stable operation and maintenance of the heat exchanger, reducing maintenance workload caused by scaling.

[0059] The cross-sectional widths of the first turbulence port 4 and the second turbulence port 5 decrease and then increase along the direction of medium flow. This design helps to further enhance the turbulence effect. Through this structure, the medium undergoes a cross-sectional change as it flows through the turbulence port, thereby increasing the complexity and turbulence of the flow and thus improving heat exchange efficiency. In addition, this cross-sectional change design also helps to prevent fouling at the turbulence port, facilitating later cleaning and maintenance.

[0060] The cross-sectional width variation of the first spoiler 4 and the second spoiler 5 can be achieved in various ways for the newly added technical features. For example, the cross-sectional width variation effect can be achieved by changing the geometry or size of the spoiler. As a preferred embodiment, the inlet and outlet of the spoiler can be designed with different widths, or a transition section can be set in the middle part of the spoiler to achieve dynamic variation of the cross-sectional width.

[0061] By employing this cross-sectional width variation design, this application effectively addresses the problem of insufficient turbulence in traditional turbulence structures, further enhancing the turbulence of the medium and heat exchange efficiency. Simultaneously, this design reduces the risk of fouling, simplifies subsequent cleaning, and extends the service life of the heat exchanger. Compared to existing technologies, this application offers significant advantages in improving heat exchange efficiency and reducing maintenance costs.

[0062] As one specific embodiment of the heat exchange plate 1 in this application, refer to Figures 1-3 It also includes an inlet 11 and an outlet 12 for connecting the flow guide cavity. The technical solution of this application achieves the connection of the flow guide cavity by setting an inlet 11 and an outlet 12 on the heat exchange plate 1. This design ensures smooth flow of the medium within the flow guide cavity, effectively improving heat exchange efficiency. The inlet 11 and outlet 12 allow the medium to quickly enter and exit the flow guide cavity, further optimizing the flow path of the medium, reducing flow resistance and residence time, thereby improving overall heat exchange performance.

[0063] Specifically, the inlet 11 and outlet 12 can be located at different positions on the heat exchange plate 1 to ensure that the medium is evenly distributed within the flow guiding cavity. For example, the inlet 11 can be located at one end of the heat exchange plate 1, while the outlet 12 is located at the other end, forming a complete flow loop. As a preferred embodiment, the diameters of the inlet 11 and outlet 12 can be adjusted according to actual needs to accommodate media with different flow rates, thereby further optimizing the heat exchange effect.

[0064] By adding a sealing ring 13 to the heat exchange plate 1, the sealing performance of the plate heat exchanger can be effectively improved, preventing media leakage. This design ensures stable media flow within the guide cavity during the use of the plate heat exchanger, especially under high pressure or high temperature environments, thereby improving heat exchange efficiency and extending the service life of the equipment.

[0065] The material of the sealing ring 13 can be selected according to the specific application environment, such as rubber, silicone, or other high-temperature and corrosion-resistant materials. The installation position and method of the sealing ring 13 can be varied; for example, the sealing ring 13 can be embedded in the groove of the heat exchange plate 1, or fixed to the surface of the heat exchange plate 1 by adhesive. Its shape and size can also be adjusted according to the structure of the heat exchange plate 1 to ensure optimal sealing performance.

[0066] By setting a sealing ring 13 on the heat exchange plate 1, the technical solution of this application effectively solves the shortcomings of traditional plate heat exchangers in terms of sealing performance. This not only improves the sealing effect but also reduces the risk of media leakage, thereby enhancing the safety and reliability of the equipment. Therefore, this solution has significant application value in plate heat exchangers.

[0067] As another specific embodiment of this application, refer to Figure 3 , Figure 4 and Figure 5 Multiple heat exchange plates 1 are stacked to connect the turbulence channels 2 on adjacent end faces to form turbulence chambers. The cross-sectional area of ​​the turbulence chambers along the medium flow direction first increases and then decreases. By optimizing the design of the turbulence structure, the turbulence effect of the plate heat exchanger is significantly improved, the structural strength is enhanced, and it is easier to clean scale buildup.

[0068] Specifically, this application involves providing flow guiding cavities on both the front and back sides of the heat exchange plate 1, and then arranging several sets of turbulence-inducing flanges 3 at intervals along the medium flow direction within these cavities. These turbulence-inducing flanges 3 have trapezoidal cross-sections and their height is less than the depth of the flow guiding cavities, thereby forming turbulence channels 2 between adjacent turbulence-inducing flanges 3. Furthermore, first turbulence-inducing ports 4 and second turbulence-inducing ports 5 are respectively provided on adjacent turbulence-inducing flanges 3 to connect adjacent turbulence-inducing channels 2. These turbulence-inducing ports are diagonally distributed, and their cross-sectional width along the medium flow direction first decreases and then increases.

[0069] Regarding the newly added technical feature, namely, the stacking of multiple heat exchange plates 1 to connect the turbulence channels 2 on adjacent end faces to form turbulence chambers, where the cross-sectional area of ​​the turbulence chambers along the medium flow direction first increases and then decreases, this design can be implemented in various ways. For example, the heat exchange plates 1 can be stacked in a specific manner so that the turbulence channels 2 on adjacent end faces naturally connect after stacking, forming continuous turbulence chambers. By controlling the density of the stacking and the design of the heat exchange plates 1, the cross-sectional area of ​​the turbulence chambers can be varied, thereby further enhancing the turbulence effect.

[0070] Therefore, this application optimizes the stacking method of the heat exchange plates 1, connecting the turbulence channels 2 on adjacent end faces to form a turbulence chamber with varying cross-sectional area, further enhancing the turbulence of the medium and the heat exchange efficiency. Compared with the prior art, the design of this application not only improves the heat exchange efficiency but also enhances the structural strength, facilitates the cleaning of scale buildup, and extends the service life of the heat exchanger.

[0071] In addition, as a preferred option, the heat exchange plate 1 is made of one or more of stainless steel, titanium alloy, nickel alloy, and aluminum alloy.

[0072] The technical solution of this application aims to solve the technical problems of traditional turbulence structures, such as limited turbulence effect, low strength, and easy fouling. By using materials such as stainless steel, titanium alloy, nickel alloy, and aluminum alloy, the corrosion resistance and mechanical strength of the heat exchange plate 1 can be significantly improved, extending the service life of the heat exchanger. In addition, these materials have good processing performance and thermal conductivity, which helps to further improve heat exchange efficiency.

[0073] Specifically, stainless steel offers excellent corrosion resistance and strength, making it suitable for various media environments; titanium alloys possess high strength and corrosion resistance, making them particularly suitable for use in high-temperature and high-pressure environments; nickel alloys exhibit excellent corrosion resistance and thermal conductivity, making them suitable for harsh chemical environments; and aluminum alloys are lightweight and have good thermal conductivity, making them suitable for applications requiring reduced equipment weight. Therefore, by selecting appropriate materials, the performance of plate heat exchangers can be optimized according to different operating environments and requirements.

[0074] In summary, by employing one or more materials such as stainless steel, titanium alloy, nickel alloy, and aluminum alloy, this application not only solves the technical problems of traditional turbulence structures, but also provides a variety of material options to meet different application needs, further enhancing the performance and service life of plate heat exchangers.
