two-phase heat transport technology

The satellite telecommunications industry is currently undergoing significant evolutions. Future communication satellites need to accommodate a rapidly growing demand in data transfer, combined with more flexibility. For example, there is a strong need for Very High Throughput Satellites capable of delivering up to Tb/s over wide coverage areas and an active phased array antenna is a powerful...

two-phase heat transport technology

Carbon fibre reinforced polymer (CFRP) composite sandwich panels are becoming commonplace in satellite designs due to their high strength and low mass. While excellent for the mechanical engineer they create difficulties for the thermal engineer due to their poor thermal conductance. This presents problems for a traditional satellite architecture where units are mounted on a panel and the...

two-phase heat transport technology

The increasing demand in image quality provided by forthcoming observation missions requires both the need to use very low-CTE materials for focal planes, such as Silicon Carbide (SiC), and the need to accommodate electronics as close as possible to the detector. Such a highly integrated focal plane thus implies an efficient Thermal Control to drain the dissipated power and ensure a high...
