AIRCRAFT/SPACECRAFT FLUID COOLING SYSTEM AND AIRCRAFT/SPACECRAFT FLUID COOLING DEVICE

摘要

Provided are an aircraft/spacecraft fluid cooling system and an aircraft/spacecraft fluid cooling method in which a fluid in a pipe installed in aircraft or spacecraft can be cooled efficiently so that the amount of fluid required for cooling the fluid can be reduced. A fluid cooling system (1) includes a feed line (6) that feeds a fluid from a storage tank (4) to a pump (8), and a cooling section (26) that expands a propellant having traveled through the pump (8), feeds the propellant to the outer periphery of the feed line (6) so as to cool the propellant in the feed line (6), and discharges the expanded propellant outside.
