two-phase heat transport equipment (TPHTE)


ECSS-E-ST-31-02C Rev.1


hermetically closed system filled with a working fluid and transporting thermal energy by a continuous evaporation and condensation process using the latent heat of the fluid


  • NOTE 1 A fluid evaporates in the heat input zone (evaporator) and condenses in the heat output zone (condenser).
  • NOTE 2 This is in contrast to a single-phase loop where the sensible heat of a liquid is transported (a liquid heats up in the heat input zone and cools down in the heat output zone).
