This paper describes the results of Engineering Development Unit (EDU) testing of a graded-groove Variable Conductance Heat Pipe (VCHP). This EDU pipe contains all the essential design features of an end-item unit, including multiple bends, flex sections, stainless steel transport section and high heat flux evaporator.Testing covered a wide range of environments including hot and cold condenser temperatures, hot and cold reservoir sink temperatures, and varying evaporator powers.A control algorithm was also developed which was designed to minimize warm-up time of the evaporator, minimize overshoot of the evaporator temperature, and maintain a stable evaporator temperature after warm-up.Testing was performed to determine whether the VCHP reservoir needed to be cooled during testing in an ambient environment. Results of the model correlation are also presented.
