Heat transfer by convection of a heat sink with fins calculator and equations.
Heat sink fins calculation.
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.
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.
A reference link has been placed below the calculator for further reading.
Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance.
H air film convective coefficient a exposed surface area of the fins.
P perimeter of the fins.
The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.
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.
