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
Design the right heat sink for your application
The HeatSinkCalculator is the perfect software tool for engineers and designers to quickly and easily design and analyze a heat sink. Air and liquid cooling, optimized for temperature, weight or pressure drop.
Used by companies around the world
Effortlessly find your optimum design
No need to guess what heat sink dimensions produce the best design. The calculator will automatically find the dimensions that give the lowest temperature, the lightest heat sink or the lowest pressure drop, while keeping your power sources below a temperature limit.
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.
Quickly determine the best cooling method for your design
Analyze natural convection cooled heat sinks in multiple orientations for your application. Are you using a fan for high power components? Evaluate the fan cooled heat sink's performance by entering the fan curve data points. Select among impinging, ducted and bypass flow based on your application. Using liquid cooling? Analyze liquid-cooled heat sinks with water or ethylene/propylene glycol mixtures in ducted or bypass flow.
