This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters.
How does the heat transfer conduction calculator works.
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.
Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions.
Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance.
The heat transfer conduction calculator below is simple to use.
The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.
Heat sink thermal resistance delta t for each component part of the heat sink.
A reference link has been placed below the calculator for further reading.
The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink.
How does the heat sink calculator work.
Multiple heat sources attached to the heat sink can be evaluated.
This heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base.
Tj rjc rcs rsa pd ta where tj is the maximum target temperature of the junction.
Enter the thermal conductivity of your material w m k.
The heat sink size calculator is based on a well established equation for estimating heat sink volume during the early stages of heat sink design.
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.
The heat source is assumed to cover the entire base of the heat sink.
