Abstract: Dry ice cooling systems and methods of making dry ice cooling systems are disclosed. According to embodiments, dry ice cooling systems include a compression container including compressed liquid carbon dioxide. The dry ice cooling systems include a dry ice container coupled to the compression container to receive the liquid carbon dioxide and house dry ice as it forms. The dry ice container includes a liquid coolant. Further, the dry ice cooling system includes a heat exchanger to couple a heat-generating source to the dry ice container.

Abstract: An apparatus includes a thermal battery, which includes a housing and one or more battery cells within the housing. Each battery cell includes an anode, a cathode, and an electrolyte. The electrolyte in each battery cell is configured to be in a solid state when the battery cell is inactive. The apparatus also includes a phase change material around at least part of the housing. The phase change material is configured to conduct external heat into the housing in order to melt the electrolyte in each battery cell and activate the battery cell. The phase change material is also configured to change phase in order to reduce conduction of the external heat into the housing.

Abstract: Thermal control of powered systems on-board a flight vehicle is achieved by leveraging the latent heat storage capacity of Phase Change Materials (PCMs) to maintain the operating temperature at or slightly above the melting temperature of the PCM. The invention is particularly well suited for use with powered systems such as laser, microwave emitters, RF sensors and high-density power electronics that must operate at a desired operating temperature while generating considerable waste heat in a confined packaging volume of smaller flight vehicles such as missiles, rockets, guided projectiles, drones or other such platforms.
