Heat Sink Calculator

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.

Heat sink calculator.

This calculator and tutorial computes the junction temperature of a power electronics device given the maximum ambient temperature and the heat sink thermal resistance. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. 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. A reference link has been placed below the calculator for further reading.

The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. 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. How does the heat sink calculator work. The expected transient performance for three different pcm options suitable for your application is plotted.

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. Multiple heat sources attached to the heat sink can be evaluated. Act s phase change material heat sink calculator provides initial scoping estimates for your thermal storage requirements including approximate volume weight and temperature profile. In our experience it generally estimates the overall heat sink volume within 15 of a final design.

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