70 Numerical Simulation and Experiment for Structure Optimization of Small Gravity Heat Pipe Radiators

Heat pipe radiator is a heat recovery unit of high efficiency. It is widely applied to the electronic equipment systems for its high heat transfer efficiency, small transfer temperature drop, simple structure, easy control and no energy consumption. This paper applied professional heat analysis software SINDA/FLUINT to study on the performance of radiator, and established a radiator bench to test the performance of radiator. The simulated result and testing measurements were compared for argument. It deeply analyzed the application of heat pipe technology in improvement of heat dissipation in electronic industry, which offered theoretical basis for wide application of the technology.
