Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
Heat sink fins calculation.
Fins are used to increase heat transfer area and provide a cooling effect.
The heat source is assumed to cover the entire base of the heat sink.
A reference link has been placed below the calculator for further reading.
The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.
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.
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.
In our experience it generally estimates the overall heat sink volume within 15 of a final design.
However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow.
