Abstract
In some implementations, a thermal management system includes a heat source and a heat pipe connected to the heat source and configured to transfer thermal energy from the heat source to a plurality of condensers, each of the plurality of condensers branching off from a main pipe of the heat pipe. The heat pipe can be a variable conductance heat pipe containing a working fluid vapor. Each condenser contains a reservoir of non-condensable gas (NCG). At least one of the condensers can be controlled by heating/cooling the respective reservoir of NCG, by reservoir volume changing via bellows, and/or by NCG amount changing via NCG insertion/extraction.
