Passive Cooling

Passive cooling is a technique used in space and astronautical engineering to regulate the temperature of a spacecraft or satellite without using any external power source. It involves the use of materials and design features that allow for the dissipation of heat through radiation, convection, and conduction. Passive cooling systems can include radiators, heat pipes, thermal blankets, and coatings that reflect sunlight. These systems are designed to maintain a stable temperature range for sensitive equipment and electronics, prevent overheating, and extend the lifespan of the spacecraft or satellite. Passive cooling is particularly important for long-duration missions where power consumption is a critical factor and where active cooling systems may not be feasible.
