Résumé
Heat pipe devices, for their typical working mechanisms, are particularly suitable for zero gravity applications (satellites). This work reports the results of experimental tests carried out on a heat pipe facility designed to investigate the thermal-hydraulic performance of a water heat pipe. The device layout makes it possible to simulate a heat pipe working in space applications. The evaporating section, completely lined by wicks (sintered stainless steel), and nearly plane shaped, is housed in a cylindrical container. Two test series were performed with reference to different heater sizes obtaining for the evaporating heat flux a value of 13 W.cm-2 in the first series and of 20 W.cm-2 in the second one, using a smaller heater size. This result means that it is potentialy possible to use more compact evaporators and to work at higher system operating pressure values.
