What is a stamped or plate fin?

A stamped fin (also known as a plate fin) refers to a type of heat transfer component used in heat exchangers. These fins are thin metal plates attached to a conductor (such as a heat sink or metal block) to dissipate heat from sensitive components or devices. Acting as a thermal bridge between the component and the ambient air, plate fins accelerate heat dissipation, typically featuring 1 to 2...
