Multiple heat sources attached to the heat sink can be evaluated.
Aluminum plate heat sink calculator.
Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
Heat sink thermal resistance delta t for each component part of the heat sink.
Heat sink calculator this heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base.
To estimate the dimensions of the flat plate heat sink you need to determine the path of heat flowing to the surroundings and the magnitude to which that path resists the flow of heat.
In our experience it generally estimates the overall heat sink volume within 15 of a final design.

Flat plate heat sink dimensions.
The heat sink can be a simple plate or the metal wall of the enclosure housing the component as shown in figure 1.
The heatsinkcalculator offers online heat sink analysis software that allows you to analyze plate fins heat sinks cooled via radiation and natural or forced convection.
