This paper presents an experimental investigation of an open loop pulsating heat pipe (OLPHP), where several issues related to its performance were evaluated. Tests were conducted with different working fluids for the OLPHP operating at both vertical and horizontal orientations. The experimental results show that the system presented better performance when operating at horizontal orientation, as lower evaporation section temperatures were achieved. Regarding the working fluids used, the system showed better performance when acetone was used on vertical orientation and methanol on horizontal orientation.
