### EXPERIMENTAL INVESTIGATION AND CFD ANALYSIS OF A AIR COOLED CONDENSER HEAT PIPE

**ABSTRACT**

In the present work a heat pipe of one meter length and 0.031m outer diameter was constructed and the experiments are conducted to determine the surface and vapour temperature at steady and transient conditions for two different input power in the evaporator section and cooling the condenser section by air. A CFD analysis was also carried and the results under steady state conditions are compared with the results obtained from the experiments and reported in this paper.
