[0028] S130. When a component association instruction is received, an association relationship between components of the target model is constructed based on the component association instruction to obtain a target heat exchanger model.

[0029] The component association instruction may be an instruction for constructing a connection relationship between model components. The target heat exchanger model may be a model of the heat exchanger finally obtained. Specifically, according to the component association instruction, the corresponding target model components may be connected in series based on the corresponding connection relationship to obtain the target model components.

[0030] The technical solution provided by the embodiment of the present invention displays a model component list on a preset interface when a design trigger instruction is received; wherein the model component list includes at least: a pipe component, a pipeline component, a chamber component and a heat exchange module; when a component interaction instruction is received, multiple target model components are determined from the model component list based on the component interaction instruction; when a component association instruction is received, an association relationship between the target model components is constructed based on the component association instruction to obtain a target heat exchanger model.

The device can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0032] like Figure 2 As shown, the heat exchanger design method includes the following steps:

[0033] S210: When a design trigger instruction is received, a model component list is displayed on a preset interface.

[0034] Among them, the design trigger instruction can be a trigger instruction to start designing a heat exchanger model. The preset interface can be a preset interactive interface for designing a heat exchanger model. The interface can include a variety of interactive controls, and the user can click on the corresponding interactive controls to perform model design operations; accordingly, the preset interface can also display the corresponding heat exchanger model after the design operation is performed in real time. Exemplarily, there can be a design trigger control on the preset interface, and the user can click on the design trigger control so that the device receives the design trigger instruction. Furthermore, the model component list can include multiple model components. Specifically, the model component list includes at least: a connecting pipe component, a pipeline component, a connecting chamber component and a heat exchange module. Among them, the model component can be understood as a unit that constitutes a heat exchanger model. The user can select the required model components by himself, and then splice and combine the selected model components to obtain the corresponding heat exchanger simulation model. Exemplarily, a heat exchanger model can be constructed based on the Modelica language. Exemplarily, Figure 3 It is a structural schematic diagram of a heat exchanger provided in an embodiment of the present invention. Figure 4 Schematic diagram of a heat exchanger model provided by an embodiment of the present invention. Figure 4 As shown, in terms of expression, the heat exchanger model can be composed of connecting pipes, pipelines, connecting chambers and heat exchange modules.

[0035] S220. When a component selection instruction is received, determine a plurality of initial model components from the model component list according to the component selection instruction.

[0036] The component selection instruction may be a selection instruction for a model component. Exemplarily, the user may issue the component selection instruction by clicking and dragging. The initial model component may be an original model component without any parameter adjustment. Specifically, the corresponding model component may be determined from the model component list according to the component selection instruction, and the determined model component may be used as the initial model component.

[0037] S230. For each initial model component, based on the parameter adjustment instruction corresponding to the initial model component, adjust the component parameters in the initial model component to obtain the target model component.

[0038] Among them, the parameter adjustment instruction may be an instruction to adjust the component parameters of the initial model component. Exemplarily, the component parameters may include: the inner diameter of the tube-side heat exchange tube, the outer diameter of the tube-side heat exchange tube, the average length of the tube-side heat exchange tube, the number of tube-side heat exchange tubes, the arrangement of the U-shaped heat exchange tube bundle, the orientation of the U-shaped tube, the number of radial nodes on the tube wall, the heat transfer factor inside the tube, the roughness of the inner wall of the tube, the energy loss coefficient of the flow energy inside the tube, the heat transfer tube tube fouling thermal resistance, the tube sheet elevation of the tube bundle, the inlet cavity volume, the inlet cavity flow length, the outlet cavity volume, the outlet cavity flow length, the flow area, the hydraulic diameter, the percentage of the height of the arched baffle, the shell-side heat transfer factor, the number of sections in the non-heat exchange tube bundle area, the wall roughness, the local pressure drop loss coefficient, the heat transfer tube tube outer fouling thermal resistance, the radial node number, the radial thickness and other parameters. Exemplarily, Table 1 is a schematic diagram of the component parameters corresponding to the model components in the heat exchanger model.

[0042]

[0043]

[0044] Among them, the use of inlet and outlet connecting cavities makes it easier to connect the vertical U-type heat exchanger with external components. When the number of inlets and outlets of the external components is large, the connection between the pipes and the transmission of fluid data are more difficult. The inlet and outlet connecting cavities allow the fluid introduced from the external components to be first collected in the inlet connecting cavity and then distributed to the pipe pass. After flowing in the pipe pass, it is collected in the outlet connecting cavity and then flows out of the heat exchanger to be distributed to the external components.

[0045] Furthermore, the target model component may be a model component obtained after adjusting component parameters. Specifically, the component parameters of the initial model component may be adjusted based on the parameter adjustment instruction to obtain the target model component.

[0046] Optionally, based on the parameter adjustment instruction corresponding to the initial model component, the component parameters in the initial model component are adjusted to obtain the target model component, including: when an adjustment trigger instruction is received, a parameter interface corresponding to the initial model component is displayed; the parameter interface includes adjustable parameters corresponding to the initial model component; when a parameter adjustment instruction is received, at least one target parameter and a target parameter value corresponding to the target parameter are determined from the adjustable parameters according to the parameter adjustment instruction; for each target parameter, the parameter value of the target parameter is adjusted to the target parameter value.

[0047] Among them, the adjustment trigger instruction can be a trigger instruction for starting to adjust the component parameters. Exemplarily, there can be an adjustment trigger control on the preset interface, and the user can click on the initial model component that needs to adjust the parameters, and then click on the adjustment trigger control to issue the adjustment trigger instruction. Furthermore, when the device receives the adjustment trigger instruction, it can display the parameter interface of the initial model component corresponding to the instruction. The parameter interface can include adjustable parameters corresponding to the initial model component and parameter bars corresponding to the adjustable parameters.

[0048] Among them, the adjustable parameter may be a component parameter that can be adjusted corresponding to the initial model component. Further, the parameter adjustment instruction may be an adjustment instruction for the component parameter. The target parameter may be a component parameter that needs to be adjusted. The target parameter value may be a target value corresponding to the target parameter. Specifically, the component parameter selected by the parameter adjustment instruction may be used as the target parameter, and then the parameter value of the target parameter in the parameter adjustment instruction may be used as the target parameter value, and finally, for each target parameter, the parameter value corresponding to the target parameter may be adjusted to the target parameter value.

[0049] Optionally, for each initial model component, the component parameters in the initial model component are adjusted based on the parameter adjustment instructions corresponding to the initial model component, including: when the initial model component is a heat exchange module, determining the percentage of the arched baffle height and the tube bundle arrangement corresponding to the heat exchange module based on the parameter adjustment instructions; determining the target in-tube heat transfer coefficient corresponding to the heat exchange module based on the percentage of the arched baffle height and the tube bundle arrangement, and adjusting the in-tube heat transfer coefficient of the heat exchange module to the target in-tube heat transfer coefficient.

[0050] Among them, the percentage of the height of the arcuate baffle without a circle can be a parameter used to represent the fluid disturbance effect produced by the baffle in the shell side. Among them, the fluid disturbance will increase the heat transfer coefficient between the shell side fluid and the U-tube. Further, the tube bundle arrangement method can be the arrangement method of the tube bundle in the heat exchanger. Specifically, the tube bundle arrangement method includes an equilateral triangle arrangement and a square arrangement. The target tube heat transfer coefficient can be a coefficient for correcting the heat transfer relationship in the heat exchange tube. Exemplarily, based on the percentage of the height of the arcuate baffle without a circle and the tube bundle arrangement method, the formula for determining the target tube heat transfer coefficient J is as follows:

[0051] Tube bundle equilateral triangle or rotated equilateral triangle arrangement:

[0052] Re<=200J=0.641*Re 0.46*(Z-15) / 10 +0.713*Re 0.473*(25-Z) / 10

[0053] 200 <Re<5000J=0.491*Re 0.51*(Z-15) / 10 +0.673*Re 0.49*(25-Z) / 10

[0054] Re>5000J=0.35*Re 0.55*(Z-15) / 10 +0.539*Re 0.539*(25-Z) / 10

[0055] Tube bundles are arranged in a square or a square with a 45° tilt:

[0056] Re<=200J=0.641*Re 0.46*(Z-15) / 10 +0.713*Re 0.473*(25-Z) / 10

[0057] 200 <Re<1000J=0.491*Re 0.51*(Z-15) / 10 +0.673*Re 0.49*(25-Z) / 10

[0058] Re>1000J=0.378*Re 0.554*(Z-15) / 10 +0.41*Re 0.5634*(25-Z) / 10

[0059] Where Re is the Reynolds number, Z is the percentage of the arcuate baffle's height, and J is the heat transfer coefficient in the target tube.

[0060] S240. When a component association instruction is received, corresponding target model components are connected in series based on the component association instruction to obtain a regional model.

[0061] Among them, the component association instruction can be an instruction for constructing a connection relationship between model components. Exemplarily, the user can issue a component association instruction on the preset interface by dragging, parameter input or connecting lines. The regional model can be a model of a sub-region in a heat exchanger. Specifically, the heat exchanger may include multiple model areas such as inlet and outlet areas, inlet and outlet pipe heat exchange areas, and non-heat exchange areas. Accordingly, the regional model may include: at least one of an inlet and outlet area model, an inlet and outlet pipe heat exchange area model, and a non-heat exchange area model. Furthermore, according to the component association instruction, the corresponding target model components can be connected in series based on the corresponding connection relationship, thereby obtaining multiple regional models.

[0062] S250. When a region association instruction is received, corresponding region models are connected in series based on the component association instruction to obtain the target heat exchanger model.

[0063] The regional association designation may be an instruction for establishing a connection relationship between regional models. For example, the user may issue a regional association instruction by dragging, inputting parameters, and connecting lines on a preset interface. The target heat exchanger model may be a model of the heat exchanger finally obtained. Specifically, the regional models may be connected in series based on corresponding connection relationships according to the regional association instruction, thereby obtaining the target heat exchanger model.

[0064] Optionally, after obtaining the target heat exchanger model, when receiving a simulation model building instruction, a list of auxiliary components can be displayed on a preset interface; when receiving an auxiliary component interaction instruction, multiple target auxiliary components can be determined based on the auxiliary component interaction instruction; when receiving an auxiliary component splicing instruction, the target auxiliary component and the target heat exchanger model can be spliced ​​based on the auxiliary component splicing instruction to obtain the target simulation model.

[0065] Among them, the simulation model construction instruction can be a trigger instruction for building a total simulation model. Exemplarily, the user can click the corresponding simulation model construction control in the preset interface to issue a simulation model construction instruction. Further, the auxiliary component can be a component that assists the heat exchanger model in building a total simulation model. The auxiliary component list can include auxiliary components such as tube flow inlet components, tube pressure outlet components, shell flow inlet components, shell pressure outlet components and pipeline components. The auxiliary component interaction instruction can be an interaction instruction for the auxiliary component. Exemplarily, the user can issue the auxiliary component interaction instruction by clicking, dragging, manual input, etc. The target auxiliary component can be an auxiliary component for the user to subsequently build a simulation model. Specifically, multiple target auxiliary components can be determined from the auxiliary component list based on the auxiliary component interaction instruction. The target simulation model can be the simulation model of the heat exchanger that is finally determined. Specifically, the user can select the auxiliary components he needs, and then splice and combine the selected auxiliary components with the target heat exchanger model to obtain the corresponding target simulation model.

[0066] Optionally, when an auxiliary component interaction instruction is received, multiple target auxiliary components are determined based on the auxiliary component interaction instruction, including: when an auxiliary component selection instruction is received, multiple initial auxiliary components are determined from an auxiliary component list according to the auxiliary component selection instruction; for each initial auxiliary component, based on a parameter adjustment instruction corresponding to the initial auxiliary component, component parameters in the initial auxiliary component are adjusted to obtain the target auxiliary component.

[0067] Among them, the auxiliary component selection instruction may be a selection instruction for an auxiliary component. Exemplarily, the user may issue an auxiliary component selection instruction by clicking and dragging. The initial auxiliary component may be an original auxiliary component that has not undergone parameter adjustment. Specifically, the corresponding auxiliary component may be determined from the auxiliary component list according to the auxiliary component selection instruction, and the determined auxiliary component may be used as the initial auxiliary component. Among them, the parameter adjustment instruction may be an instruction to adjust the component parameters of the initial auxiliary component. Further, the target auxiliary component may be the auxiliary component obtained after adjusting the auxiliary component parameters. Specifically, the auxiliary component parameters of the initial auxiliary component may be adjusted based on the parameter adjustment instruction to obtain the target auxiliary component.

[0068] For example, in order to better understand the technical solution provided by the present invention, a specific embodiment is introduced below:

[0069] 1. Build a U-type heat exchanger model test example. The test model diagram is as follows Figure 5 As shown, the test model includes a flow inlet component, a vertical U-type heat exchanger model component, a pressure outlet component, and a conventional pipeline component.

[0070] 2. Set the initial boundary conditions: conventional pipeline diameter 0.02m, pipeline length 1m, tube side mass flow inlet 2kg / s, inlet temperature 26.85℃, tube side pressure outlet pressure 1.68MPa. Shell side mass flow inlet 2kg / s, inlet temperature 96.85℃, shell side pressure outlet pressure 1.68MPa.

[0071] Structural parameters: The inner diameter of the heat exchanger tube is 0.02m, the outer diameter is 0.022m, the average length is 2m, there are 10 heat exchange tube bundles arranged in a square, the heat exchange tube bundles face upward, the inlet and outlet cavity volume is 0.01m3, the cavity flow length is 0.5m, the shell flow area is 0.1m2, the hydraulic diameter is 0.05m, the flow length is 2.5m, and the arcuate baffle has a height percentage of 25% of the roundness.

[0072] 3. Simulation settings: simulation time 300s, output time step 0.01s, Dassl algorithm, calculation accuracy 0.0001.

[0073] 4 Simulation results: The results of the calculations of the system model based on the two-phase flow pipeline constructed by Modelica are compared with those of other commercial thermal hydraulic software under the same boundary conditions. The results show that the simulation results of the system model based on the two-phase flow pipeline constructed by Modelica are almost consistent with those of other commercial thermal hydraulic software, with an error range of less than 5%. This shows that the content of the present invention can be well applied to industrial simulation modeling projects, and can achieve model reuse and expansion by taking advantage of the modular modeling advantages of the Modelica language.

[0074] The technical solution provided by the embodiment of the present invention is as follows: when a design trigger instruction is received, a model component list is displayed on a preset interface; when a component selection instruction is received, multiple initial model components are determined from the model component list according to the component selection instruction; for each initial model component, based on the parameter adjustment instruction corresponding to the initial model component, the component parameters in the initial model component are adjusted to obtain the target model component; when a component association instruction is received, the corresponding target model components are connected in series based on the component association instruction to obtain a regional model; when a regional association instruction is received, the corresponding regional models are connected in series based on the component association instruction to obtain the target heat exchanger model.
