SUBDOMAINS:

1. Heat Pipes: Covers all technologies related to heat pipes, e.g. constant conductance, variable conductance and heat pipe diodes.
2. Capillary-Driven Loops: Covers all technologies related to capillary-driven two-phase heat transport loops, including Capillary Pumped Loops (CPLs) and Loop Heat Pipes (LHPs).
3. Mechanically-Pumped Two-Phase Loops: Covers all elements and associated technologies for mechanically pumped two-phase heat transport loops.
4. Mechanically-Pumped Single-Phase Loops: Covers all elements and associated technologies for mechanically pumped single-phase heat transport loops.
5. Heat Switches: Covers all elements and technologies for heat switches, e.g. based on LHPs or mechanically driven.
