The primary goal of this program is to develop the significant weight-saving potential of phase change material (PCM) microtube heat exchangers for NASA spacecraft thermal management. Mezzo will utilize microtube heat exchanger technology along with topography optimization and 3D printing to allow for cutting-edge performance and weight savings.
PCM heat exchangers assist in the smoothing out of thermal energy during part pulse or cyclic operation and allow for short-term thermal storage. This ability allows for thermal systems to be designed around non-peak operating conditions which allows for a smaller thermal system.
One market is the quickly growing directed energy market, which could greatly benefit from the load-leveling capabilities of microtube PCM heat exchangers. The directed energy weapon market was valued at $4.3 billion in 2021 and is projected to reach $10.1 billion by 2026.
