Thermal - Heat Sinks

The 782653B01000G is a thermal exchange device typically placed between a heated surface, like a processor, and an external environment, like air, in order to prevent overheating. It is an example of a "heat sink."

Application Field

Heat sinks are used in a wide variety of applications. They are commonly found in computers, laser printers, and TVs, where their function is to cool a processor or electronic component. Heat sinks are also used in electric vehicles to spread heat away from the motor and battery, allowing the car’s performance and range to be improved. Heat sinks are also found in the automotive industry, avionics, hydroelectric generators, and more.

Working Principle

A heat sink works by increasing the surface area for heat transfer between a hot source and a cooler environment using the principle of conduction. Heat sink designs may also utilize convection or radiation to improve cooling, but these are secondary to the conduction cooling method.

When a heat sink is in contact with a hot surface, such as a processor, the heat sink devices absorbs and dissipates the heat away from the component and into its surroundings. Heat sink can come in a variety of shapes, sizes, and materials depending on the application. These materials and designs can help to provide better cooling and better protection from the environment.

Once containing the heat, the heat is then quickly dissipated by conduction. This is done by transferring heat away from the heat sink device and into its environment. The efficiency of the heat transfer is determined by both the surface area available for the transfer as well as the material of the heat sink.

The application of a 782653B01000G heat sink increases the surface area for heat transfer between the hot source and its cooler environment. By providing increased contact over the heat source surface, it allows for a greater amount of heat to be dissipated quickly and safely. Additionally, the 782653B01000G also allows for more control over the temperature of the hot surface.
