The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.
Multiple heat sources attached to the heat sink can be evaluated.
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.
Enter the thermal conductivity of your material w m k.
This heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base.
Heat sink thermal resistance delta t for each component part of the heat sink.
The formula to find the required thermal resistance of the heat sink given by jluciani is basically correct but is missing a term for the ambient temperature ta.
This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters.
In our experience it generally estimates the overall heat sink volume within 15 of a final design.
