The EEATCS collects heat from the Interface Heat Exchangers (IFHX) located on the U.S. Laboratory module, circulates the working fluid, anhydrous ammonia, via the Pump and Flow Control Subassembly (PFCS), and rejects heat to space …
International Space Station's Cooling System: How It Works ...
2013年5月10日 · The International Space Station’s active thermal control systems (ATCS) pump fluids through closed-loop pipes. A liquid-ammonia coolant loop along the station’s main truss keeps the station ...
Spacecraft thermal control - Wikipedia
Excess waste heat created on the spacecraft is rejected to space by the use of radiators. Radiators come in several different forms, such as spacecraft structural panels, flat-plate radiators mounted to the side of the spacecraft, and panels deployed after the …
7.0 Thermal Control - NASA
2010年7月2日 · A radiator is a dedicated surface for dissipating excess heat via radiative heat transfer and has a high IR emissivity and low solar absorptivity, an optical property combination typically referred to as “radiator properties.”
thermal radiators are derived from the International Space Station (ISS) design utilizing a honeycomb core and embedded flow paths with slightly thicker face-sheets.

A radiator circuit on the ISS is leaking - CNN
2023年10月9日 · A backup radiator circuit on the Nauka module of the Russian-controlled portion of the ISS has sprung a leak. The crew is not in any danger, according to Roscosmos.
The External Active Thermal Control System (EATCS) is a closed loop single phase system that mechanically pumps liquid ammonia to cool the avionics, payloads and electronic equipment onboard the International Space Station (ISS).
Integrated Truss Structure - NASA
2023年9月27日 · The Integrated Truss Structure (ITS) is made up of 11 segments plus a separate component called Z1 that are attachment points for the solar arrays, thermal control radiators and external payloads on the space station. The solar arrays were also delivered with the S3/S4 and P3/P4 trusses.
