Heat Sink for Processor

A heat sink is a term for a part or assembly that transfers heat generated within a solid material to a liquid medium, such as air or a liquid.

 Approach air velocity, choice of material, fin (or other protrusion) design and surface treatment are numerous the design factors which influence the thermal resistance, i.e. thermal performance, of a heat sink. engineering application of heat sinks is in the thermal management of electronics, often computer central processing unit (CPU) or graphics processors. For these, heat sink attachment methods and thermal interface materials also influence the temperature of the processor. Thermal adhesive(also called thermal grease) is added to the base of the heatsink to help its thermal performance. Theoretical, experimental and numerical methods can be used to select a heat sink's thermal performance.
