Elaboration of thermal control systems on heat pipes for microsatellites Magion 4, 5 and BIRD

Inverse thermal analysis of the drying zone of the evaporator of an axially grooved heat pipe

“…In order to overcome increasing heat dissipation requirements, heat pipe design improvements have been performed to enhance heat transfer ability for the needed operating conditions. In particular, thermal control of telecommunication satellites is mainly based on axially grooved heat pipes [1,2]. The performance improvement of the heat transport versus the mass is an essential parameter of such a heat transfer device.…”

Equivalent thermal conductivity of heat pipes

“…Heat pipes have the advantages of high thermal transportation capability, excellent isothermal performance, alterable thermal flux density, and constant temperature characteristics. Thus, they have many applications, such as in spaceflights [1,2], reclaiming heat from waste smoke in plants [3,4], and computers [5,6], with a few of them used in mechanics [7,8].…”

Analysis of heat spreading performance of acetone-filled heat pipe at low temperatures for using in satellite honeycomb panels

“…INPE adopted a research program CONTER, which includes the development of two-phase technology employing low-pressure and low hazardous acetone as an alternative working fluid. Acetone heat pipes already have been used in thermal control of the Mageon 4 and 5 satellites, being in operation for more than 4 years (Baturkin et al, 2002). Acetone-filled heat pipe radiator assemblies present very competitive design mass characteristics against ammonia for the same HP heat transport capability (Vlassov et al, 2006).…”
