ABSTRACT:
Water coolant circulating in a closed loop may be cooled by passing it through a heat exchanger coil embedded within a block of heavy water ice. The ice will maintain the water, passing through the coil, at a temperature approximately 39.degree. F. Maintenance of the working fluid at this temperature prevents it from freezing in coolant tubes. The system is particularly adapted for a liquid cooling space garment which must effectively conduct away heat from an astronaut's body when an astronaut exerts himself during physical activity.
