Thermavant Technologies, L.L.C. SBIR Phase I Award, July 2022

In response to NASA SBIR Topic S16.07, ThermAvant Technologies, LLC proposes to develop highnbsp;conductance cryogenic oscillating heat pipes for space applications. Working fluids will be investigated at temperatures between 77 Knbsp;and 230 K. The oscillating heat pipes will be developed in a range of geometries to demonstrate high effective thermal conductivities innbsp;complex 3D geometries and small form factors, and demonstrate ambient storage conditions. Specifically, ThermAvant aims to develop oscillating heat pipes that can handle heatnbsp;fluxes up to and above 5 W/cm2 with power levels up to 100 W over distances of up to 1 m. nbsp;
