Abstract    The enhancement of operating life cycle of electronic devices necessitates the development of efficient cooling techniques. Therefore, in the present work the effects of employment of Phase Change Material, in the adiabatic section of heat pipe for electronic cooling applications were experimentally and numerically investigated. Tricosane (100 ml) is chosen as PCM in this study, where Al2O3 nanoparticles were dispersed in PCM by an ultrasound mechanism with volume fractions of 0.5, 1 and 2%. Transient thermal behavior of the evaporator, energy storage materials and condenser were studied during the charging process with heating powers of 13, 18 and 23W. The performance of system with Tricosane and nanoparticles improved for 1% concentration and reduced for 2% concentration; which concludes for the optimized doping of nanoparticles. In addition, CFD simulation of heat pipe is carried out for the above mentioned opertating conditions. The experimental and simulation results were compared at various operating conditions to establish correlation between them. The numerical results observed to match closely with experimental results. Finally, the thermal performance of heat pipe-PCM module is predicted through CFD simulation for the filling volumes of 115 cc and 130 cc at 13 W, 18 W and 23 W.

چکیده    افزایش چرخه عمر عملیاتی دستگاه های الکترونیکی، توسعه تکنیک های خنک کننده کارآمد سیتم خنک کننده را ضروری می سازد. بنابراين، در اثر حاضر، اثرات كاربرد مواد تغيير فاز در بخش آدئيوباتيک لوله گرمايي براي كاربردهاي خنك كننده هاي الكتريكي به صورت آزمايشگاهي و عددي مورد بررسي قرار گرفته است. در این مطالعه به عنوان PCM در نظر گرفته شده است که در آن، نانوذرات آلومینیوم در PCM با استفاده از دستگاه همرن مافوق صوت با کسر حجمی 0.5، 1 و ٪2 پراکنده شده اند. رفتار حرارتی گذرا تبخیر کننده، مواد ذخیره سازی انرژی و کندانسور در طول فرایند شارژ با توان های 13، 18 و W23 مورد مطالعه قرار گرفت. عملکرد سیستم با تریکوسن و نانوذرات اکسید الومینیوم با غلظت 1٪ بهبود یافته و برای غلظت 2٪ کاهش داشته است، که نتیجه برای دوپینگ نانوذرات بهینه شده است. علاوه بر این، شبیه سازی CFD لوله گرما برای شرایط ذکر شده فوق انجام گردید. نتایج آزمایش و شبیه سازی در شرایط عملیاتی مختلف برای ایجاد همبستگی بین آنها مقایسه گردید. نتایج عددی مشاهده شده است که با نتایج تجربی انطباف دارد. در نهایت، عملکرد حرارتی ماژول گرما لوله-PCM از طریق شبیه سازی CFD برای حجم پر شدن 115 و 130 میلی لیتر در 13 و 18 و 23 وات است.
