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