| Abstract: |
| According to the thermal load requirements of a model of vehicle-mounted power supply,thermal simulation analysis of each power module and chassis in the power supply chassis is carried out. Establish the physical 3D model according to the physical vehicle power supply. Determine the meshing parameters and the parameters of each component of the power supply chassis. Calculate the thermal stacking of the internal components of the vehicle power supply and the overall surface heat dissipation performance of the chassis under air-cooling conditions. Perform finite element thermal simulation analysis by ANSYS Icepak software. Verify the chassis design conditions,temperature rise magnitude. To optimize and improve the appearance design,heat dissipation form,internal component arrangement,internal component power selection for the reference of this model of vehicle power supply chassis. |
