SDBS对铜-水脉动热管启动及传热性能影响
Influence of SDBS on start time and heat transfer performance of pulsating heat pipe
摘要
Abstract
Surface tension is one of the important factors that influences the behaviors of the working fluid bubbles, such as generation, pulsation split and merge. Furthermore, the heat transfer performance of pulsating heat pipe (PHP) is affected. Three concentration solutions 0.001%, 0.005% and 0.009% were configured using sodium dodecyl benzene sulfonate (SDBS) as solute and deionized water as base fluid. The surface tension of water was decreased by 42.2% after addition of 0.005% SDBS, while little change of the specific heat, density and viscosity. Both the start-up and heat transfer performance of PHP were test with the concentration solutions under different heating power input. The experimental results indicated that SDBS can reduce the start-up time of the pulsating heat pipe. Start-up time of 0.001% solution was the shortest with the heating power input no more than 90 W. Differently, the addition of SDBS has little effect on the start-up time under high heating power input. At steady working station, the heat transfer performance of PHP was improved by adding SDBS.关键词
