finnedcoil
A finned coil is a heat exchanger component that uses metal fins attached to a core tube or plate to increase its surface area for heat transfer. The fins are typically made of aluminum, copper or stainless steel, chosen for thermal conductivity, corrosion resistance and cost. The core tube or plate carries the fluid, while the fins provide a large area for heat exchange with a secondary medium such as air, water or another fluid.
In heating, ventilation, and air‑conditioning (HVAC) systems, finned coils are commonly found in air‑source heat pumps,
Design considerations include the fin geometry (length, thickness, spacing), the material and its thickness, and the
Finned coils offer advantages such as high heat transfer efficiency, compact size and relatively low manufacturing
