Heat Sink Calculator

Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions.

Heat sink calculator.

Multiple heat sources attached to the heat sink can be evaluated. This calculator and tutorial computes the junction temperature of a power electronics device given the maximum ambient temperature and the heat sink thermal resistance. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. How does the heat sink calculator work.

In our experience it generally estimates the overall heat sink volume within 15 of a final design. Multiple heat sources attached to the heat sink can be evaluated. A reference link has been placed below the calculator for further reading. 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.

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. The expected transient performance for three different pcm options suitable for your application is plotted. 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.

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.
