Find or design the right heat sink for your application
Design a heat sink in minutes not hours
Find your optimum design with a single click
Automatically search and analyze off-the-shelf heat sinks
No special training necessary
Find off-the-shelf designs to meet your needs
Automatically search hundreds of off-the-shelf heat sinks from leading manufacturers to find the most appropriate and cost effective designs to meet your needs.
Specify the temperature and heat sink dimensional constraints and the HeatSinkCalculator will search the database of off-the-shelf heat sinks and display the products that meet those constraints

Analyze multiple flow conditions
The HeatSinkCalculator allows you to select either forced or natural convection flow based on your particular application.
Specify forced convection with an approach flow velocity, volumetric flow rate or input a fan curve.
Natural convection analysis can be conducted with the heat sink in the vertical or horizontal orientations.
Radiation effects can be included or excluded from the analysis.
Calculate optimum dimensions
No need to guess what heat sink dimensions will result in the lowest temperature. Using mathematical optimization the HeatSinkCalculator will determine the optimum fin thickness, base thickness and number of fins that produces the lowest heat source temperature
You can specify the maximum and minimum values of the dimensions being varied to suit your design constraints
Easily specify power source variables
Along with power source dimensions and value, you can specify the use of thermal interface materials and value of junction to case resistance for an encased power source
Flexible unit selection
Specify the units you are most comfortable using for input variables and results. You can choose from the most commonly used metric and imperial units
