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