Basics of Loop Heat Pipe Temperature Control
Modern spacecraft are using Loop Heat Pipes (LHP) more frequently. However, there are no practical guidelines to help LHP users know how and when to use the active temperature control. Most spacecraft payloads and instruments must operate in a required, sometimes-narrow temperature range. Outside this temperature band the instruments either operate poorly or …

Air Handling Unit Basics: Components, Specifications & Types
6. Heat Pipe. Heat pipes are used to further improve the dehumidification capability of AHUs. They work passively to provide heating to the cold air thereby allowing the cooling coil to be at a lower temperature so that more water vapor can condense. To dehumidify more, the surface temperature of the AHUs cooling coil must be reduced.
