Heat Sinks are disarmingly simple. Extruded, stamped or forged, aluminum or copper, heat sinks are vital to the best operation of our hot computing systems. Most times, the choice of the best heat sink solution is a matter of considering only its total device power dissipation. While a heatsink may appear structurally simple, the fluid flow through its fin field and thermal coupling with its surrounding create a more complex problem. Actually, the most important characteristic of a heat sink is its thermal resistance value.
Our free White Paper, “Heat Sink Thermal Resistance Changes with Length and Width” will give our readers all the necessary tools to calculate a heat sink’s thermal resistance value so you can make the best choice.
