Heat Sink Fins Calculation

Fins are used to increase heat transfer area and provide a cooling effect.

Heat sink fins calculation. However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow. Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions. The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink. Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance.

P perimeter of the fins. A reference link has been placed below the calculator for further reading. In our experience it generally estimates the overall heat sink volume within 15 of a final design. Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.

H air film convective coefficient a exposed surface area of the fins. The heat sink size calculator is based on a well established equation for estimating heat sink volume during the early stages of heat sink design.
