Modeling and Simulation of Heat Pipe Radiator Based on Modelica

In order to verify the design of heat pipe type radiation radiators, and evaluate whether the performance of the radiator can meet the requirments of engineering application indicators, this paper establishes a radiator collector ring model, a heat pipe thermal resistance network model, a pseudo wick thermal conduction model, and a fin and radiation unit model. A radiator simulation code using the Modelica language was developed based on the MWORKS platform, and simulation were conducted on different diversion schemes of a two-stage heat pipe type radiator. The research results indicate that the radiator simulation code can perform reasonable caculations on different design schemes. Therefore, the models and modeling methods used in this paper can be used for radiator design and optimization analysis.
