Heat Pipe Technology for Current Spacecraft and High Power Thermal Management

The application of conventional axially grooved heat pipes to the thermal control of attached shuttle payloads, instruments on free flyers, communications satellites and body mounted radiators for space station common modules is discussed. Also presented is the evolution of an advanced axially grooved design for application to the space station's space erectible radiators (SERS). Capillary Pumped Loop (CPL) development status and its application to high power thermal management for space station applications are also included.
