Current Mechanically Pumped Two-Phase Thermal Control Loop Developments

Thermal control techniques for infrared imaging on nanosatellites

“…However, employing the same system for small satellites and nanosatellites ranging from 10 kg to 100 kg increases the risk to a higher degree. Conventional mechanically pumped thermal control fluid loop systems are single-phase [Delil, 2004b], relying on the heat capacity of the working fluid.…”

“…MPFL with freon-11 was chosen for MPF's HRS due to its following attractive features. [Delil, 2004b]: 1) Ease of integration with the spacecraft, 2) No orientation constraints, 3) Control temperatures of remotely located components, 4) Modulate the system's temperature with changing environmental conditions and equipment power, 5) Versatile thermal control system for future missions (Smaller in size, cheaper, and lighter). Since then, MPFL has been used in various space exploration missions.…”
