基于弹簧-质量-阻尼模型的单环闭式脉动热管传热特性
Heat transfer characteristics of single-loop closed pulsating heat pipe based on spring-mass-damper model
摘要
Abstract
In order to explore the heat transfer performance of single-ring closed pulsating heat pipe,the forced damped oscillation equation of two liquid columns in pulsating heat pipe was obtained by theoretical deduction.A spring-mass-damper model of liquid column oscillating motion of single-ring closed pulsating heat pipe considering gas-liquid phase transition was established.Based on this model,the heat transfer characteristics of single-ring closed pulsating heat pipe considering the nonlinear changes of elastic coefficient and mass were obtained.Experimental studies were carried out to verify the correctness of the mathematical model.The results show that when the filling rate is 60%and the heating power is 60 W,the heat transfer performance of the pulsating heat pipe is the best.The start-up time of the pulsating heat pipe is positively correlated with the chaotic characteristics and the chaotic characteristics are positively correlated with the heat transfer characteristics.关键词
