  2. Spacecraft thermal control - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_thermal_control

    The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).

  3. Heat pipe - Wikipedia

    en.wikipedia.org/wiki/Heat_pipe

    This allows spacecraft heat pipes to be several meters long, in contrast to the roughly 25 cm maximum length for a water heat pipe operating on Earth. Ammonia is the most common working fluid for spacecraft heat pipes. Ethane is used when the heat pipe must operate at temperatures below the ammonia freezing temperature.

  4. Liquid droplet radiator - Wikipedia

    en.wikipedia.org/wiki/Liquid_Droplet_Radiator

    Such space systems require advanced high-temperature thermal control systems. Liquid metal heat pipes with conventional radiators are considered ideally suited for such applications. [5] However, the required radiator surface area is huge, hence, the system mass is very large. The liquid droplet radiator (LDR) has an advantage in terms of the ...

  5. External Active Thermal Control System - Wikipedia

    en.wikipedia.org/wiki/External_Active_Thermal...

    The International Space Station (ISS) External Active Thermal Control System (EATCS) [1] maintains an equilibrium when the ISS environment or heat loads exceed the capabilities of the Passive Thermal Control System (PTCS). Note Elements of the PTCS are external surface materials, insulation such as Multi-Layer Insulation (MLI), or Heat Pipes.

  6. Multi-layer insulation - Wikipedia

    en.wikipedia.org/wiki/Multi-layer_insulation

    The golden areas are MLI blankets on the Mars Reconnaissance Orbiter. The principle behind MLI is radiation balance. To see why it works, start with a concrete example - imagine a square meter of a surface in outer space, held at a fixed temperature of 300 K (27 °C; 80 °F), with an emissivity of 1, facing away from the sun or other heat sources.

  7. Loop heat pipe - Wikipedia

    en.wikipedia.org/wiki/Loop_heat_pipe

    A loop heat pipe (LHP) is a two-phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator. LHPs are similar to heat pipes but have the advantage of being able to provide reliable operation over long distance and the ability to operate against gravity. They can transport a ...
