Modeling and Simulation of Dynamic Heat Dissipation Based on S-Function under MATLAB Simulink Environment

Abstract

This paper discusses a model implementation of dynamic heat dissipation simulation based on S-Function under MATLAB Simulink Environment. The subtle changes in heat dissipation process can be simulated through this model and the model can be easily used to build thermal control system. A multiloop thermal system, including two payloads and fluid loop system, has been built to test this model. From the simulation results we can analyze the efficiency of heat dissipation in different payload distributions and different flow rate allocations. This model is possibly used for high accuracy temperature control and complex multiloop thermal system analysis.
