The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.
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.
H air film convective coefficient a exposed surface area of the fins.
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.
In our experience it generally estimates the overall heat sink volume within 15 of a final design.

Heat transfer by convection of a heat sink with fins calculator and equations.
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.
Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
