Abstract
The goal of this study is to study the heat transfer in a single loop pulsating heat pipe with a stainless steel evaporator and the rest of its body made of Nylon®, using R134a as refrigerant fluid and only thermocouples to measure the average temperatures in the pulsating heat pipe. Through a simple formulation the thermal resistance of the system was calculated. It has been found that the thermal resistance varies from near 0.2 K/W down to near 0.06 K/W depending on the filling ratio and heat input in the system. The result was compared with another in the literature, indicating consistency and a satisfactory performance.
