摘要
Abstract
The thermal management systems for vehicular electronic devices often operate under vibrational conditions,and effective vibrational control can enhance convective heat transfer of the fluid.However,the current understanding of the influence of vibration on the heat transfer performance of single-phase spray cooling remains unclear.To investigate the thermal performance of single-phase spray cooling under various vibrational conditions,a closed-loop vibrating surface spray cooling system has been established in this work.Through experimental investigation,the study explores the influence mechanisms of Vibrational Reynolds Number(Rev),Dimensionless Acceleration Number(Ac),amplitude,and frequency on single-phase spray cooling performance.The findings indicate that an increase in Rev and amplitude results in a suppression of heat transfer coefficient and heat transfer enhancement factor;specifically,spray cooling is suppressed by 37%when the heating power is 200 W and Rev is 4 947.Conversely,higher Ac and frequency can improve the thermal performance of spray cooling,enhancing it by 17%when the heating power is 200 W and the Ac number is 3.6.The results from this study can be utilised for optimising spray cooling thermal management systems under vibrational conditions.关键词
