Focusing on the concern of predicting the LHP thermal performance, this paper presents an experimental investigation of a LHP. The experimental performance of the LHP is analyzed, which used acetone as the working fluid, operating in a range of heat to be dissipated form 2 to 70 W. The LHP presented reliable operation during both startup and power cycles applied to it. The experimental results were then compared to a mathematical model, which was able to predict the LHP operation temperature. This comparison presented good agreement between the experimental and calculated results using the model. The results gathered from this experimental investigation are intended to be used in future LHP application in both ground and space projects.
