- Liquid Cooling Garments
Liquid cooling garments (LCGs) form a primary component of spacesuit thermal management. These garments circulate chilled water throughout a network of tubes embedded within the suit, absorbing metabolic heat generated by the astronaut. The heated water is then routed to a radiator, where heat is dissipated into space. LCGs are tailored to provide uniform cooling, preventing localized hotspots and ensuring astronaut comfort during strenuous tasks. For example, during extended spacewalks for space station maintenance, LCGs maintain a stable core body temperature, preventing heatstroke and allowing astronauts to maintain cognitive function and physical endurance.
- Radiators
Radiators are external heat exchangers that radiate excess heat into space. These panels are strategically positioned on the spacesuit or associated equipment to maximize heat dissipation. The efficiency of a radiator is influenced by factors such as surface area, emissivity, and orientation relative to the sun. Proper radiator design is crucial for maintaining thermal equilibrium within the system. In the context of lunar surface operations, radiators must be capable of rejecting heat even under conditions of direct sunlight, necessitating advanced coatings and thermal insulation.
- Thermal Insulation
Multi-layered insulation (MLI) blankets minimize heat transfer between the spacesuit and the surrounding environment. MLI consists of multiple layers of thin, reflective material separated by vacuum gaps, reducing both radiative and conductive heat transfer. This insulation is particularly important for preventing heat gain from solar radiation and heat loss to the cold vacuum of space.
