What is an air fin cooler?

   An air fin cooler, also known as an air-cooled heat exchanger or fin fan cooler, is a type of heat exchanger used to cool fluids by exchanging heat with ambient air. It consists of finned tubes through which a hot fluid flows, and air is forced over the fins to remove heat from the fluid. Air fin coolers are commonly used in industrial applications where water scarcity or contamination concerns make water-based cooling impractical.
