Abstract: The objective of the present work is to investigate the heat transport limitations and overall heat transfer coefficient for a Copper – Acetone heat at different vapor temperatures. A dimensional analysis has been made to the overall heat transfer coefficient in the heat pipe, A new correlation for the overall heat transfer coefficient has been obtained . It has been found that latent heat vaporization , the pipe diameter and Reynolds number are the parameter affects the overall heat transfer coefficient. A computer program was used to calculate heat pipe limits theoretical and correlated overall heat transfer coefficients using the data of (6). The sonic, capillary, and entrainment limits are increased with increasing the vapor temperature but the boiling limit is decreased with the increasing of vapor temperature. The correlated function that relates overall heat transfer coefficient and vapor temperature is very close to the theoretical overall heat transfer coefficient.
