Abstract

See full text

Systems and methods for embedding a thermal management system in an electric propulsion (EP) system is presented. According to one aspect, one or more oscillating heat pipes (OHPs) are provided within functional elements of the EP system. Each OHP includes channel segments that include a sealed working fluid. The channel segments are joined to form a continuous serpentine channel with a channel path that alternates between hot and cold regions of the EP system. According to another aspect, the functional elements of the EP system are reduced to a single monolithic structure with an embedded OHP. The single monolithic structure may be a single material or a multi material. According to yet another aspect, the functional elements are elements of a magnetic circuit of the EP system, including one or more of a backplate, an outer pole, an inner pole, or a center pole.
