Sink

In space and astronautical engineering, a sink refers to a device or system that is used to absorb or dissipate heat generated by electronic components or other equipment. In the microgravity environment of space, heat dissipation becomes a critical issue as there is no natural convection to carry away the heat. Sinks are typically made of materials with high thermal conductivity, such as copper or aluminum, and are designed to maximize the surface area in contact with the equipment to be cooled. They may also incorporate fins or other features to increase the surface area further. Sinks are commonly used in spacecraft, satellites, and other space-based systems to prevent overheating and ensure reliable operation of electronic components.
