Heat Sink Calculator

In our experience it generally estimates the overall heat sink volume within 15 of a final design.

Heat sink calculator.

Act s phase change material heat sink calculator provides initial scoping estimates for your thermal storage requirements including approximate volume weight and temperature profile. Multiple heat sources attached to the heat sink can be evaluated. The heatsinkcalculator offers online heat sink analysis software that allows you to analyze plate fins heat sinks cooled via radiation and natural or forced convection. Advanced plate fin heat sink calculator myheatsinks advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.

How does the heat sink calculator work. Heat sink convection with fins calculator heat transfer design and engineering heat transfer by convection of a heat sink with fins calculator and equations fins are used to increase heat transfer area and provide a cooling effect. The calculator will let you know if the maximum junction temperature could be exceeded for a given power and likewise will tell you the maximum power that the device can handle for a given maximum power. Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance.

The expected transient performance for three different pcm options suitable for your application is plotted. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. A reference link has been placed below the calculator for further reading.

Multiple heat sources attached to the heat sink can be evaluated. 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.
