Our research deals with the simulation and analysis of temperature rising of equipment. By comparing to temperature analysis, the module, we derived the temperature rising of for different Aspect was more suited for transfer, and the studies that was better suit for herd distribution. The current method of combining the finite element method will actually experiments derives the temperature rise more comprehensively.
The biggest challenger is to make the simulation results compatible with the experiment and to reduce the error. Currently, the simulation error is mainly reduced by solving the problem multiple times. Our protocol reduce the error or a single solution model that cannot satisfy the temperature rising program or It can provide a multifaceted solution to a problem of temperature rising or electrical equipment, combined with the variety of finite element method for interpretation.
In the future, we will devote ourselves to the analysis and the research of thermal stress and string electrical equipment passed by temperature rising programs, and we will also focus on the temperature rising program of multiple operating conditions in the future. Begin the protocol by setting up the ice pack model. To do so, right click on the selected component, click Edit, and then go to Properties"to set the material for both the surface and solid materials.
First, set the material properties by designating all circuit solid materials with surfaces using copper polished surface as copper pure. For the panel components, select aluminum 6061T6 material with a surface coating of paint AL surface, having an emissivity of 0.35. Select the model and click on Set"in the edit menu.
Then choose multi-level meshing level to adjust the mesh settings. Set the external cabinet and all boundaries to a mesh level of two. For all other components, set the mesh level to three.
Finally, open Mesh control"and click Generate"to create the mesh. Import the geometric model of the temperature field enclosure, established using the design software for meshing. Determine the grid size to balance efficiency and accuracy.
For solution setup, set the directions of the solution domain cabinet to Opening. In the software, select Problem step. Under basic parameters, check the surface-to-surface radiation model.
Choose Zero equation"for turbulent flow regime. Select the gravity option for natural convection and set the ambient temperature to 20 degrees Celsius. In the file settings, choose Volumetric heat losses"for EM Mapping and select All objects shown"to complete the loss settings.
To set up the steady state thermal model, maintain the displayed material properties in the material settings. By clicking on Thermal load generation, generate the ohmic losses resulting from the eddy current field simulation analysis in the steady state thermal module. Click on the convective temperature value and set it to 20 degrees Celsius with a convective coefficient of five watt per square meter Celsius, applied to the inner walls of the cabinet, components, and external cabinet.
Apply the settings and click on the generate option to generate a cloud map of the temperature distribution. Set the output to solve for temperature by clicking on Solve and output results. Compare the temperature values obtained from the steady state thermal temperature field solving module with those from the ice pack temperature field solution module.
