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 sink fins calculation.
The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.
H air film convective coefficient a exposed surface area of the fins.
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.
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.
Fins are used to increase heat transfer area and provide a cooling effect.
A reference link has been placed below the calculator for further reading.
P perimeter of the fins.
Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
The heat source is assumed to cover the entire base of the heat sink.
