Abstract
A Capillary Pump Loop (CPL) is a two-phase heat transfer device considered a useful solution for thermal control applications in spacecrafts, satellites and electronic components. Purpose of this paper is to study aspects of the working state of the Capillary Pump Loop. A two dimensions computational model was designed to analyze heat transfer and liquid saturation inside the wick. Different cases were studied by changing the saturation temperature of the working fluid, water in our case, the heat load applied to the evaporator external wall, the wick heated length and the inclination angle to the horizontal level. Temperature flow results, inside the wick and at the evaporator exit, are presented, giving a better understanding of the function under several circumstances which enables more efficient evaporator design, capable to transfer bigger amounts of heat.
