Used by companies around the world

Get to your final design faster

Iterate though multiple heat sink design analyses in a few minutes to find the best design for your application and avoid building multiple costly prototypes

Dimensions/Optimization Image

Effortlessly find your optimum design

No need to guess what heat sink dimensions produce the lowest temperature design. The calculator will automatically determine them for you.

Power Source Image

You don't need to be a thermal expert

Simple and straight forward inputs make it easy to run your analysis. Enter your heat sink dimensions, power(heat) source values and flow conditions, and immediately get results.
