This HeatSink Designer Online tool is designed to calculate the optimal dimensions and performance metrics of a rectangular heatsink with fins for natural convection and radiation cooling. It allows users to input key parameters such as heatsink dimensions, material properties, and environmental conditions.

These calculations aim to maintain the heatsink surface temperature under a given power dissipation and ambient temperature.
