Same Sky (Formerly CUI Devices) Heat Sinks

Passive heat exchangers that transfer the heat generated by an electronic component to a fluid medium, often air or a liquid coolant, dissipating it away from the device to maintain an optimal operating temperature. They are designed to maximize the surface area in contact with the medium surrounding it. They are usually made out of copper or aluminum due to their high thermal conductivity.
