Question

To manage heat in the vacuum of space, which specific component is used to move thermal energy away from extraction equipment to external radiators?

Accepted Answer

The component used to transport thermal energy from equipment to external radiators is called a fluid thermal loop, or more specifically, a pumped fluid loop. Because there is no air in the vacuum of space to carry heat away through convection, spacecraft rely on a closed system of pipes filled with a circulating liquid, such as water or ammonia. This coolant absorbs heat from electronic components and transfers it to the radiators, which are large panels that dissipate the energy into space as infrared radiation. Think of this system like the cooling system in a car, where a pump continuously circulates liquid to carry engine heat to the radiator so it does not overheat.
