What is a heat sink in nature?
Under natural convection cooling, the temperature of the air within the heat sink’s fins increases due to heat from the heat source. The higher temperature air is less dense than the surrounding air and rises our of the heat sink.
What is considered a heat sink?
A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device’s temperature.
What is the difference between active and passive heat sinks?
A passive heat sink is one with no moving parts. An active heat sink has moving parts.
Who are the manufacturers of Mouser heat sinks?

What is the length of a heat sink?
Heat Sinks Extrusion Cut to Length, 11.81 Inch, 4.429″. Wide, High Aspect Heatsink 17080-11.81, 0.59 Thermal Resistance Degree Celsius w/3 Inch Length.
What happens when there is no air flow around a heat sink?
The inlet air temperature of the heat sink is therefore higher, which also results in a higher heat-sink base temperature. If there is no air flow around the heat sink, energy cannot be transferred. A heat sink is not a device with the “magical ability to absorb heat like a sponge and send it off to a parallel universe”.
