The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:
Skiving machine producing copper heat sink fins. Skiving is also used for the manufacturing of heat sinks for PC cooling products. A PC cooler created by skiving has the benefit that the heat sink base and fins are created from a single piece of material (copper or aluminum), providing improved heat dissipation and heat transfer from base to fins.
Hydro Extruded Solutions is a manufacturer of extruded aluminium profiles. Hydro has the largest global aluminium extrusion-based operation in the world, counting 100 production sites in more than 40 countries, and has 22,400 employees. [1] Hydro's head office is located in Oslo, Norway.
Thus, adding a fin to an object, increases the surface area and can sometimes be an economical solution to heat transfer problems. One-piece finned heat sinks are produced by extrusion, casting, skiving, or milling.
Aluminum is also much lighter than copper, offering less mechanical stress on delicate electronic components. Some heat sinks made from aluminum have a copper core as a trade off. The heat sink's contact surface (the base) must be flat and smooth to ensure the best thermal contact with the object needing cooling.
