Forced Convection

Specify forced convection with an approach flow velocity, volumetric flow rate or input a fan curve

Natural Convection

Natural convection analysis with the heat sink in the in the vertical or horizontal configurations

Radiation

The ability to include or exclude the effects of radiation and adjust the surface emissivity

Material Properties

The option to select from a list of predefined materials or input custom material properties

Below is the demo version of the Heat Sink Calculator with the length fixed at 50mm and the height at 25mm. You can try it out for free. The full version allows to you to vary all the parameters shown in the demo version. Sign up for the full version here.
