H air film convective coefficient a exposed surface area of the fins.
Heat sink fins calculation.
P perimeter of the fins.
Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance.
The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink.
A reference link has been placed below the calculator for further reading.
Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions.
However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow.
Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
Heat transfer by convection of a heat sink with fins calculator and equations.
The heat source is assumed to cover the entire base of the heat sink.
Fins are used to increase heat transfer area and provide a cooling effect.
