Spacecraft multi-directional loop heat pipe thermal systems

摘要

Multi-directional (reversible and parallel) loop heat pipe thermal systems for use on a spacecraft. The multi-directional loop heat pipe thermal systems may comprise reversible or parallel loop heat pipes that provide efficient thermal pathways that are directionally independent between any combination of equipment mounting panels and radiator panels. Loop heat pipes of the reversible loop heat pipe thermal system are coupled between opposite ends of respective evaporator/condenser flanges. The evaporator/condenser flanges each comprise a condenser and an evaporator. The parallel loop heat pipe thermal system comprises pairs or sets of parallel heat pipes that are respectively coupled between a condenser flange and an evaporator flange. The reversible or parallel loop heat pipes may be routed to a multiple number of radiator panels in order to optimize the use of a radiator panel by always transporting heat to the coolest radiator panel.
