In our experience it generally estimates the overall heat sink volume within 15 of a final design.
Heat sink design calculator.
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.
As with the natural convection heat sink calculations the radiation heat dissipation q r1 from the area a 1 is calculated using equation 9.
The variables ε is the surface emissivity of the heat sink.
A reference link has been placed below the calculator for further reading.
Heat transfer design and engineering.
Heat transfer by convection of a heat sink with fins calculator and equations.
Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions.
How does the heat sink calculator work.
Typical values are listed in the article the importance of radiation in heat sink design.
This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters.
The user can choose between natural or forced convection and or radiation for the modes of heat transfer.
Fins are used to increase heat transfer area and provide a cooling effect.
The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.
This heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base.
Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow.
