Abstract
The purpose of this paper is to study the effect of CTAB on the heat transfer performance of pulsating heat pipe.For this reason,a copper PHP experimental device platform was built,and the effects of different mass fractions(0～0.072%)of CTAB aqueous solution on the heat transfer performance of PHP were investigated through experiments when the liquid filling rate was 50%.The experimental results indicates that the addition of CTAB to water can enhance the pulsation frequency and heat transfer performance of the plugs within the PHP.PHP heat transfer resistance is related to heating power and CTAB concentration and decreases with increasing heating power and CTAB concentration.Specifically,at a heating power of 20 W,the CTAB aqueous solution with a mass fractions of 0.072%has the maximum enhancement efficiency(31.6%)compared to pure water PHP.However,when the heating power reaches 90 W,the heat transfer enhancement effect of adding CTAB to water for PHP is relatively weak.The study indicates that CTAB can effectively improve the heat transfer performance of PHP and increase its heat transfer efficiency.关键词
