Abstract: In connection with growing requirements for improving the environment, nowadays the world attaches importance to creation and enhancement of electric and hybrid airplanes, equipment of which is in need of effective cooling of its components heated by a passing current. The purpose of this work is to analyse the possibilities of using autonomous two-phase heat conductors (heat pipes, thermosyphons) and passive systems based on them for thermal control of equipment in electric and hybrid aircraft. The article discusses designs of heat pipes and thermosyphons, shows options for their use in electric and hybrid airplanes. The design and results of experimental studies of the kW-class loop thermosyphon with horizontal evaporator and condenser are presented. This thermosyphon has the right characteristics for use in thermal management systems: a high heat transfer capacity (up to 1.5 kW) and a short starting time.

Keywords: thermal management; passive cooling system; heat pipe; thermosyphon.
