Description

The loop heat pipe (LHP) is a passive two-phase heat transport device that is gaining importance as a part of spacecraft thermal control systems and also in applications such as in avionics cooling and submarines. A major advantage of a loop heat pipe is that the porous wick structure is confined to the evaporator section, and connection between the evaporator and condenser sections is by smooth tubes, thus minimizing pressure drop. LHPs can transfer heat efficiently up to several meters at any orientation in the gravity field. When placed horizontally, this distance can extend to several tens of meters. Loop Heat Pipes are a low-mass solution that can solve complex and far-reaching geometries that traditional heat pipe solutions cannot solve standalone
