The operational characteristics of a VCHP in the various operation conditions were investigated. A water heat pipe including nitrogen gas as a non-condensable gas was designed and manufactured using a copper tube with 12.7㎜ diameter and 480㎜ length. Experimental data showed that the length of non-active zone mostly depend on the temperature of the vapor and the non-condensable gas. And the heat flow rate was negligible parameter at the same vapor temperature in the range of the experiment. As the vapor temperature increase and the non-condensable gas temperature decrease, the non active zone was increased. The calculated data by using the flat front model and the experimental results showed same tendency.
