چکیده

Heat pipes are heat transfer devices which are widely used due to their higher effective thermal conductivity in comparison with conductive metals such as copper and aluminum. Several kinds of heat pipes exist such as pulsating heat pipe, rotating heat pipe, wick heat pipe, vapor chamber and thermosiphons. Heat pipes contain a fluid which evaporates by receiving heat at evaporator and then the vapor converts into liquid by heat dissipation in the condenser. Different types of heat pipes are categorized based on the returning mechanism of condensed fluid from the condenser to the evaporator. Nanotechnology is widely used in recent years in order to enhance heat transfer in several mediums as well as heat pipes in the form of nano-fluids or nano-surfaces. This paper gives a comprehensive review on the most recent applications of nanotechnology to enhance the performance of these heat pipes.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
