ABSTRACT

Low-temperature aluminum profiled heat pipes (HPs) with axially grooved internal walls are considered in this paper. They are mainly applied to space vehicles' thermal control systems. Longitudinal axial grooves are made as an effective capillary structure instead of traditional wicks in order to create maximal capillary head inside the HPs at minimal hydrodynamic resistance. They are manufactured while the HPs' containers are extruded from rods made of aluminum alloy. Experimental results on thermal performances of the above-mentioned HPs filled with ammonia as a cooling agent are presented. A study of the issue of the bends' affects on the performances of specially shaped aluminum axially grooved HPs is given. Aluminum axially grooved HPs built in honeycomb panels applied to space engineering have been developed by the authors. Some results on thermal engineering tests of HPs and honeycomb panels with them that have been developed by the order of the National Space Agency of Ukraine for AMPOS-SM-KF (2001-2006), Cyclon-4 (launched in 2006) Ukrainian-Russian, and other international space projects are given. Original software for simulation and prediction of thermal modes for profiled HPs (COUNT-HP) and honeycomb panels with built-in HPs (PSTAT) have been created on the basis of the developed mathematical models. Computed thermal modes for created HPs and honeycomb panels containing them in accordance with developed mathematical simulators are adduced in this paper. Long-term flight experiments proved the adequacy of the developed simulators and technical solutions for the developed HP and honeycomb panels prototypes.
