Abstract :

The closed-loop pulsating heat pipe is a small heat transfer device with a very high thermal conductivity. It can transfer sufficient heat for heat dissipation applications in modern electronic devices. The objective of this work is to study thermal performance of closed loop pulsating heat pipe with methanol as working fluid. Copper has been selected as material for heat pipe due to compatibility of copper with methanol as working fluid. Filling ratio of the working fluid significantly influence on the performance closed loop pulsating heat pipe. From the past studies it was observed that filling ratio of 30-75 % provides the best results. For this work 60 % filling ratio has been selected for this filing ratio the thermal performance of closed loop pulsating heat pipe with methanol as working fluid is investigated.
