69 Study on Heat Emission Numerical Simulation and Layout Optimization Concerning Components of Electronic Equipment Available to Purchase

In this paper, the lumped parameter mathematical model is established based on the heat transmission process of electronic component inside the sealed electronic components. The heat analysis software SINDA/FLUINT is used to make comparison of the layout of electronic components of the same quantities and conduct the analysis on optimized numerical simulation to design parameters in order to obtain the most optimized design plan concerning component. The heat equation is used to establish heat balance equations and calculate the temperature of node. In addition, the computer-aided design is utilized to accomplish a reasonable, economical, and feasible heat design to meet the indicated temperature control of electronic equipment.
