Description

Technical Field

[0001] The present invention relates to a pumping station heat dissipation system and a design method based on the Bio-TRIZ bionic theory, and is particularly applicable to the radiator technical field. Background Art

[0002] During the operation of a hydraulic system, pressure, volume, and mechanical losses will all cause energy losses in the hydraulic system, and these energy losses are converted into heat in various ways, causing the temperature of the hydraulic oil in the hydraulic system to rise. Therefore, heat dissipation is required during the long-term operation of a hydraulic pumping station. The cooling methods of a hydraulic pumping station generally include: natural cooling of the machine body, air cooling, water cooling, and cooling with a cooling agent. The cooling effect is one of the important indicators for measuring a heat dissipation device. If the heat dissipation device cannot cool the temperature of the hydraulic oil in the pumping station in time, the high temperature will change the physical properties of the hydraulic oil, increase the leakage amount, reduce the working efficiency of the pumping station, and the oil film at each sliding part of the hydraulic pumping station will be damaged, aggravating the wear of hydraulic components. Seriously, it will cause the operation of the hydraulic system of the pumping station to be unstable. Heat dissipation fins and water-cooling pipes are the main heat dissipation structures of the pumping station heat dissipation device. Due to the small heat dissipation area of traditional plate-shaped heat dissipation fins and S-shaped water-cooling pipes, and their distribution is extremely susceptible to the space of the heat dissipation device, they are not easy to clean and replace, and cannot cool the hydraulic oil in the pumping station hydraulic system in time. Therefore, the industry expects to obtain a high-performance pumping station heat dissipation device with more effective heat dissipation. Summary of the Invention

[0003] Aiming at the above technical deficiencies, a design method and system for a pumping station heat dissipation system based on the Bio-TRIZ bionic theory are provided. Combining the Bio-TRIZ bionics theory, the mapping from a biological model to an engineering model is realized to solve the problem of poor heat dissipation of the pumping station in practical engineering applications. By matching the optimized biological cases of pumping station heat dissipation through the Bio-TRIZ bionics theory, the honeycomb and vein feature structures are used to improve the heat dissipation performance of the pumping station heat dissipation device. By analyzing the honeycomb and vein structures and characteristic curves, they are applied to the optimized design of the pumping station heat dissipation device. In the pumping station heat dissipation structure, a bionic honeycomb heat dissipation fin structure is designed to effectively increase the heat dissipation area, save the internal space of the heat dissipation mechanism, and improve the overall structural stability. During the heat dissipation and transfer process, a bionic spiral heat dissipation pin column is designed to improve the heat transfer efficiency and accelerate the environmental heat transfer. At the same time, a bionic dicotyledonous water-cooling channel and transpiration water circulation system are designed to realize a circulating use system that integrates evaporation-condensation-collection of cooling water, which can timely take away the heat in the pumping station heat dissipation device, effectively solve the problem of poor heat dissipation effect of the existing pumping station heat dissipation device, and thus ensure the overall performance of the equipment and the operation efficiency of the system.

[0004] A pump station heat dissipation system includes an air-cooled heat dissipation system and a water-cooled heat dissipation system.

Compared with traditional heat dissipation fins, the heat dissipation area is greatly increased. The heat in the pump station environment is further absorbed by the spiral heat conduction pin columns (4), transferred to the external environment through the rectangular heat dissipation fins (2), and finally the hot air at the top of the pump station after circulation is discharged from the air-cooling outlet pipe (31).

[0005] The water-cooled heat dissipation system includes a cooling water inlet pipe (17), a bionic leaf vein water-cooled pipe (19), transpiration holes (20), a cooling water outlet pipe (21), a mounting fixing plate (22), a hydraulic oil collection cross pipe (23), a condensation plate (24), drainage holes (25), and a collecting pipe (26); the cooling water flows into the bionic leaf vein water-cooled pipe (19) through the inlet pipe (17), flows through 20 branch paths, evaporates through the transpiration holes (20) due to heat in the branch paths, flows through the air guide holes (11) on the bionic honeycomb fins, reaches the condensation plate (24), re-condenses, passes through the drainage holes (25), reaches the collecting pipe (26), and then flows out through the return pipe (9) from the outlet pipe (21); a water cooling circulation system that integrates water evaporation-condensation-collection is realized.

[0006] The described pump station heat dissipation system further includes an outer shell (5). The outer shell (5) with a rectangular frame structure is filled with bionic honeycomb heat dissipation fins (10). Between the bionic honeycomb heat dissipation fins (10) and the bottom of the outer shell (5), there is a bionic leaf vein water-cooled pipe (19) with a rectangular contour and simulating the leaf structure. Between the bionic leaf vein water-cooled pipe (19) and the bottom of the outer shell (5), there is an installation fixing plate (22). Among them, in front of the outer shell (5), there is a heat dissipation plate (1) through an air-cooled heat conduction plate (3).

Through the air ducts formed by the honeycomb-shaped hollow parts of the evenly arranged air cooling air holes (28) on the air distribution plate (27), heat exchange is carried out on the bionic honeycomb heat dissipation fins (10), and the heat of the bionic honeycomb heat dissipation fins (10) is transferred to the air-cooled fin heat dissipation plate (1).

[0007] In the described pump station heat dissipation system, the hydraulic oil flow channel (16) is connected to the hydraulic oil distribution cross pipe (12). Oil enters through the hydraulic oil inlet pipe (14). The hydraulic oil in the inlet pipe is evenly distributed to the hydraulic oil flow channel (16) with 18 branches through the hydraulic oil distribution cross pipe (12). Among them, the connection method between the support column (13) and the pipe clamp (15) is welding, which plays a role in supporting the entire hydraulic oil supply pipeline, used to support the hydraulic oil distribution cross pipe (12), the hydraulic oil flow channel (16), and the inlet pipe (14) for oil inlet to ensure its stable operation.

[0008] The described bionic leaf vein water-cooled pipe (19) of the pump station heat dissipation system includes an evaporation plate main body. At both ends of the evaporation plate main body, there are respectively a cooling water inlet pipe (17) and a cooling water outlet pipe (21). The evaporation plate has a leaf vein hollow structure. The evaporation plate is hollow and communicated with the cooling water inlet pipe (17) and the cooling water outlet pipe (21). On the evaporation plate, there are a plurality of transpiration holes (20) arranged according to the leaf veins. The bionic leaf vein water-cooled pipe (19) has cooling water flowing in from one main pipeline. There are 20 branch pipelines on the main pipeline. The cooling water flows into the bionic leaf vein water-cooled pipe (19) from the inlet pipe (17) and then flows out through the outlet pipe (21). The bionic leaf vein water-cooled pipe (19) is fixedly connected to the installation fixing plate (22) through fixing bolts (18).

[0009] The described pump station cooling system. The bionic leaf vein water-cooled pipe (19) adopts a dicotyledon leaf vein type water-cooled pipe distribution. There are 20 branch roads on the main pipeline. Cooling water flows into the bionic leaf vein water-cooled pipe (19) from the cooling water inlet pipe (17) and flows out through the outlet pipe (21). The transpiration holes are connected to the cooling water of the 20 branch roads. The cooling water evaporates when heated and passes through the transpiration holes (20), the air guide holes (11) on the bionic honeycomb fins, the condensation plate (24), the drainage holes (25), the collecting pipe (26) and the return pipeline (9) to realize a water cooling circulation system integrating water evaporation-condensation-collection.

[0010] The described pump station cooling system. The rectangular heat dissipation fins (2) are connected to the heat dissipation plate (1), and the connection method is welding. The outer shell (5) is connected to the air-cooled heat conduction plate (3), and the connection method is bolt connection. A water-cooled water outlet connection hole (6) and a water-cooled water inlet connection hole (33) are arranged on the outer shell (5). The bionic leaf vein water-cooled pipe (19) is connected to the installation fixing plate (22). The heat conduction pin column (4) is connected to the heat conduction plate (3).

The air cooling air holes (28) are evenly distributed on the air distribution plate (27). The air cooling air outlet pipe (31) is fixed on the rear shell (32).

[0011] The described pump station cooling system. The hollow bionic honeycomb heat dissipation fins (10) are vertically arranged with the air distribution plate (27). The hollow bionic honeycomb heat dissipation fins (10) are directly cooled by the air cooling air holes (28) evenly arranged on the air distribution plate (27). The heat retained in the hollow bionic honeycomb heat dissipation fins is timely conducted to the spiral heat conduction pin column (4) on the heat conduction plate (3), so that the heat in the radiator is further transferred through the rectangular heat dissipation fins (2), improving the heat exchange efficiency in the cooling device system.

[0012] The described pump station cooling system. The rectangular heat dissipation fins (2) are vertically arranged with the external fan. The cold air flow of the external fan directly acts on the rectangular heat dissipation fins (2). Since the rectangular heat dissipation fins (2) adopt a rectangular structure, on the one hand, it avoids the blocking of the cold air flow by the traditional plate-shaped fins, increasing the heat and cold convection heat exchange efficiency. On the other hand, the structure of the rectangular heat dissipation fins (2) increases the contact area with the air, further improving the heat dissipation capacity.

[0013] The design method of the pump station heat dissipation system based on the Bio-TRIZ bionic theory uses Bio-TRIZ to describe the problem of poor heat dissipation of the pump station, and expresses the pump station heat dissipation design problem through operation domains such as structure, substance, and space. First, determine the improvement energy and conflicts existing in the pump station heat dissipation design, establish a conflict matrix, and determine the specific solutions of Bio-TRIZ. At the same time, combine the Bio-TRIZ biological example library based on the invention principle, match the biological specific solutions of the Bio-TRIZ specific solutions, and find relevant biological specific solutions through the biological example library to support this bionic design. Then, verify from aspects such as functional similarity, structural similarity, and boundary condition similarity, and select the biological example with the highest bionic value. Finally, analyze the biological specific solutions, use the method of geometric feature reconstruction for modeling, and apply the bionic model to the optimization of the pump station heat dissipation device to solve the problem of poor heat dissipation performance.

[0014] Among them, through the Bio-TRIZ specific solutions, match and combine the Bio-TRIZ biological example library based on the invention principle to increase the heat dissipation performance of the pump station heat dissipation device. It is necessary to improve the pump station heat dissipation structure. The conflict in this optimization process is to increase the structural complexity and improve the heat dissipation performance. Use the Bio-TRIZ theory to describe the conflict in the operation domain. The conflict in the process of improving the problem is: improving the energy and deteriorating the structure. Use the Bio-TRIZ specific solutions combined with the biological example library to search for bionic examples. In order to ensure that the biological examples can indeed play the corresponding bionic role in the design process, perform similarity analysis on the bionic examples and the design objectives in terms of functional similarity, structural similarity, and boundary condition similarity. Through similarity analysis and consistency verification, finally use the honeycomb structure as the biological model for optimizing the pump station heat dissipation flow channel, and use the vein structure as the biological model for optimizing the pump station cold heat dissipation flow channel structure.

[0015] Among them, design a hollow bionic honeycomb heat dissipation fin (10). Using the honeycomb structure as a biological example, obtain a three-dimensional numerical model using reverse engineering technology. Perform non-contact scanning on the honeycomb to obtain point cloud data, and use the reverse engineering software Geomagic Studio to simplify and denoise the data in sequence, construct NURBS surfaces, and complete the reverse reconstruction of the three-dimensional honeycomb solid model. According to the biological characteristics of the honeycomb, extract the honeycomb structure characteristic parameters, use the least squares method to fit the structure parameters, obtain the curve characteristic equation and characteristic curve, and use this to optimize the honeycomb structure parameters and establish a three-dimensional bionic honeycomb heat dissipation structure for the pump station. On the one hand, utilize the self-adaptive heat transfer and dissipation function of organisms to enhance heat transfer and reduce local thermal gradients, greatly increasing the wind speed inside the honeycomb, thereby achieving a higher heat dissipation effect. On the other hand, the unique regular hexagonal structure of the honeycomb structure is relatively stable, saving space and providing a stable support for the internal structure.

[0016] Among them, a bionic leaf vein water-cooling pipe (19) is designed, taking the dicotyledon leaf vein structure as a biological example, extracting the leaf vein structure parameters according to the dicotyledon leaf vein structure; according to the distribution characteristics of the leaf veins, drawing the characteristic curve of the leaf veins in a three-dimensional rectangular coordinate system, importing the contour map into the Getdata software, extracting 300 points on the curve, using the Origin software to fit the upper curve to obtain the curve characteristic equation; using the least squares method to fit the structure parameters, optimizing the flow pattern and structure parameters of the water-cooling pipe; considering the processing complexity and cost, simplifying the bionic water-cooling channel structure, and establishing a three-dimensional bionic leaf vein type water-cooling and heat-dissipating structure for the pump station. On the one hand, through the rapid heat conduction and heat dissipation characteristics of water, the heat dissipation effect of the pump station is enhanced, and the heat dissipation speed and efficiency of the water-cooling device are greatly improved; on the other hand, a transpiration heat dissipation hole (20) is included in the structure of the leaf vein type water-cooling pipe (19). When the temperature in the pump station is too high, most of the heat in the pump station is taken away by the evaporation heat dissipation of the liquid in the leaf vein type water-cooling pipe. After the liquid evaporates, it is collected by the condensation plate (24) to realize the evaporation and recycling of the cooling water.

[0017] The described design method specifically includes the following steps:

[0018] Step 1: Explore the air-cooled bionic optimization model and water-cooled bionic optimization model suitable for the pump station radiator based on the Bio-TRIZ bionic theory; First, determine the improvement energy and conflicts existing in the pump station heat dissipation design, establish a conflict matrix, and determine the Bio-TRIZ special solution; By solving the Bio-TRIZ special solution and matching and combining the Bio-TRIZ biological example library based on the invention principle, to improve the heat dissipation performance of the pump station heat dissipation device, it is necessary to optimize the pump station heat dissipation structure. The conflict in this optimization process is to increase the structural complexity and improve the heat dissipation performance; Use the Bio-TRIZ theory to describe the operation domain of the conflict: improve the energy and deteriorate the structure; Use the Bio-TRIZ special solution to combine with the biological example library to search for bionic examples. In order to ensure that the biological examples can indeed play the corresponding bionic role in the design process, similarity analysis is carried out on the three aspects of functional similarity, structural similarity, and boundary condition similarity between the bionic examples and the design objectives. Through similarity analysis and consistency test, finally, the honeycomb structure is used as the bionic model for optimizing the pump station heat dissipation channel, and the leaf vein structure is used as the bionic model for optimizing the pump station water-cooled channel structure;

[0019] The design of the hollow bionic honeycomb heat dissipation fin and the evaporation water cooling circulation system is based on the bionic innovation method of Bio-TRIZ. A similarity comparison between the hollow bionic honeycomb heat dissipation fin and the evaporation water cooling circulation system and the pump station heat dissipation system is carried out, and the consistency is calculated and analyzed from the three aspects of functional similarity, structural similarity, and boundary condition similarity. The calculation formula is as follows:

[0020] (1)

[0021] Solve the judgment matrix P for the largest eigenvalue λ max and the eigenvector corresponding to the largest eigenvalue , and further conduct a consistency test, using the random consistency ratio CR to conduct a consistency test on the judgment matrix P :

[0022] (2)

[0023] (3)

[0024] Select the evaluation factor set of the weight coefficient as , then the similarity Q between the bionic organism and the design goal can be calculated by the following formula:

[0025] (4)

[0026] Calculated according to formula (4) Q , when Q > 0.9, it indicates that the two have high consistency in terms of structural, functional, and boundary condition similarity and can be used as a bionic optimization model; the similarity Q 1 and Q 2 of the hollow bionic honeycomb heat dissipation fin and the evaporative water cooling circulation system and the pumping station heat dissipation system are 0.9235 and 0.9536 respectively; it proves the feasibility of the two biological models of honeycomb and leaf vein;

[0027] Step 2: Design a hollow bionic honeycomb heat dissipation fin structure. Taking the honeycomb structure as a biological example, use reverse engineering technology to obtain a three-dimensional numerical model; conduct a non-contact scan of the honeycomb to obtain point cloud data, and use the reverse engineering software Geomagic Studio to simplify and denoise the data in turn, construct NURBS surfaces, and complete the reverse reconstruction of the three-dimensional honeycomb solid model; according to the biological characteristics of the honeycomb, extract the honeycomb structure characteristic parameters, use the least squares method to fit the structure parameters, obtain the curve characteristic equation and characteristic curve, and use this to optimize the honeycomb structure parameters and establish a three-dimensional bionic honeycomb heat dissipation structure for the pumping station; on the one hand. Utilize the self-adaptive heat transfer and dissipation function of organisms to enhance heat transfer and reduce local thermal gradients, and greatly increase the wind speed inside the honeycomb, so as to achieve a higher heat dissipation effect; on the other hand, the unique regular hexagonal structure of the honeycomb structure is relatively stable, which not only saves space but also provides a stable support for the internal structure;

[0028] Taking the maximum heat dissipation effect as the optimization goal, a topological optimization design of the bionic honeycomb heat dissipation structure is carried out. The mathematical model of the bionic honeycomb design is as follows:

[0029] (5)

[0030] In the formula, λ is the design parameter of each bionic honeycomb unit, that is, the side length of the regular hexagon of the honeycomb; is the design domain; l * is the dimensionless heat generation coefficient; T * is the dimensionless temperature of the unit; A Ω is the total area of the design domain; Q is the maximum heat exchange objective function; Γ is the inlet geometric boundary; V f is the volume fraction occupied by the fluid channel; p * is the dimensionless fluid inlet pressure; u * is the dimensionless flow velocity;

[0031] According to the conjugate heat transfer analysis of fluid-solid under steady laminar flow state, optimization iteration calculation is carried out to obtain the λ value of each unit. Thus, through optimization, the original 3.6 mm heat dissipation fins of the pumping station air-cooling structure are optimized into 2.0 mm bionic honeycomb units, and the optimized distribution of the bionic honeycomb air-cooling heat dissipation structure is obtained;

[0032] Step 3: Design a leaf vein type water-cooling heat dissipation structure. Taking the dicotyledon leaf vein structure as a biological example, extract the leaf vein structure parameters according to the dicotyledon leaf vein structure; according to the distribution characteristics of the leaf veins, draw the characteristic curve of the leaf veins in the three-dimensional rectangular coordinate system, import the contour map into the Getdata software, extract 300 points on the curve, use the Origin software to fit the upper curve, and obtain the curve characteristic equation; use the least square method to fit the structure parameters, optimize the water-cooling pipe flow pattern and structure parameters; considering the processing complexity and cost, simplify the bionic water-cooling channel structure, and establish a three-dimensional bionic leaf vein type water-cooling heat dissipation structure of the pumping station; on the one hand, through the fast heat conduction and heat dissipation characteristics of water, strengthen the heat dissipation effect of the pumping station, and greatly improve the heat dissipation speed and efficiency of the water-cooling device; on the other hand, a transpiration heat dissipation hole is included in the leaf vein type water-cooling pipe structure. When the temperature in the pumping station is too high, most of the heat in the pumping station is taken away by the evaporation of the liquid in the leaf vein type water-cooling pipe, and the evaporated liquid is collected by the condensation plate to realize the evaporation recycling of the cooling water;

[0033] Normalize the geometric line type of the bionic leaf vein water-cooling pipe to generate a normalized mapping spline curve. After normalization, the geometric line type can be expressed as:

[0034] (6)

[0035] Among them, X ij is the abscissa after the geometric line type is unitized, i is the arc length segment number, j is the line type label, h a is the arc length of the a-th bionic leaf vein, h j is the line type of the j th bionic leaf vein; after optimization, the original pipe diameter in the pump station is φ 16 mm is optimized to a rectangular water-cooled pipe with a main pipe diameter of 18 mm × 12 mm and each branch pipe diameter of 12 mm × 12 mm, and bionic leaf vein transpiration holes with a pore diameter of 3 mm are set on the water-cooled pipe;

[0036] Step 4: Reconstruct the bionic heat dissipation system of the pump station, and apply the hollow bionic honeycomb heat dissipation fin structure and the leaf vein type water-cooled heat dissipation structure to the overall design of the pump station. Beneficial effects

[0037] (1) The hydraulic oil heat dissipation fins adopt the bionic honeycomb hollow structure heat dissipation fins, the heat dissipation area is greatly increased, and air guide holes are distributed on the bionic honeycomb heat dissipation fins, which can quickly transfer the internal heat. Secondly, the regular hexagon geometric structure of the honeycomb is stable and effectively supports.

[0038] (2) The needle-type heat conduction pin columns are inserted into the heat conduction plate, and the heat in the heat dissipation device is timely diffused to the heat conduction plate through the heat conduction pin columns. Through the strong heat exchange effect of the heat conduction plate, the temperature in the heat dissipation device is quickly reduced, and the heat dissipation efficiency of the radiator is improved.

Use the specific solutions of Bio-TRIZ combined with the biological example library to search for bionic examples. In order to ensure that the biological examples can indeed play the corresponding bionic role in the design process, similarity analysis is carried out on the bionic examples and design objectives in terms of functional similarity, structural similarity, and boundary condition similarity.

After the liquid evaporates, it is collected by the condensation plate (24) to realize the evaporation and recycling of the cooling water.

[0070] Specifically, it includes the following steps:

[0071] Step 1: Explore the air-cooled bionic optimization model and water-cooled bionic optimization model suitable for the pumping station radiator based on the Bio-TRIZ bionic theory. First, determine the improvement energy and conflicts existing in the pumping station heat dissipation design, establish a conflict matrix, and determine the Bio-TRIZ specific solution.

Use the Bio-TRIZ theory to describe the operation domain of the conflict: improve the energy and deteriorate the structure. Use the Bio-TRIZ specific solution to combine with the biological example library to conduct bionic example search. In order to ensure that the biological example can indeed play the corresponding bionic role in the design process, similarity analysis is carried out on the three aspects of functional similarity, structural similarity, and boundary condition similarity between the bionic example and the design goal. Through similarity analysis and consistency test, finally, the honeycomb structure is used as the bionic model for optimizing the heat dissipation channel of the pumping station, and the leaf vein structure is used as the bionic model for optimizing the water-cooled channel structure of the pumping station.

[0079] According to formula (4), it is calculated that Q , when Q > 0.9, it indicates that the two have high consistency in terms of structural, functional, and boundary condition similarity, and can be used as a bionic optimization model. Through the above formula, the similarity between the hollow bionic honeycomb heat dissipation fin and the evaporation water cooling circulation system and the pump station heat dissipation system Q 1 and Q 2 are 0.9235 and 0.9536 respectively. This proves the feasibility of the two biological models of honeycomb and leaf vein.

[0080] Step 2: Design a hollow bionic honeycomb heat dissipation fin structure.

Use the least squares method to fit the structure parameters to optimize the water-cooling pipe flow pattern and structure parameters; considering the processing complexity and cost, simplify the bionic water-cooling channel structure to establish a three-dimensional bionic leaf vein type water-cooling heat dissipation structure of the pump station. On the one hand, through the fast heat conduction and heat dissipation characteristics of water, the heat dissipation effect of the pump station is strengthened, and the heat dissipation speed and efficiency of the water-cooling device are greatly improved. On the other hand, a transpiration heat dissipation hole is included in the leaf vein type water-cooling pipe structure. When the temperature in the pump station is too high, most of the heat in the pump station is taken away by the evaporation of the liquid in the leaf vein type water-cooling pipe, and the evaporated liquid is collected by the condensation plate to realize the evaporation recycling of the cooling water.

[0086] Normalize the geometric line type of the bionic leaf vein water-cooling pipe to generate a normalized mapped spline curve. After normalization, the geometric line type can be expressed as:

[0089] Step 4: Reconstruct the bionic heat dissipation system of the pump station, and apply the hollow bionic honeycomb heat dissipation fin structure and the leaf vein type water-cooled heat dissipation structure to the overall design of the pump station. The overall design of the pump station includes an outer shell (5) with a rectangular frame structure. The outer shell (5) is filled with bionic honeycomb heat dissipation fins (10). Between the bionic honeycomb heat dissipation fins (10) and the bottom of the outer shell (5), there is a bionic leaf vein water-cooled pipe (19) with a rectangular contour and simulating the leaf structure. Between the bionic leaf vein water-cooled pipe (19) and the bottom of the outer shell (5), there is a mounting fixed plate (22).
