Aluminium Heat Sink Calculator

The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.

Aluminium heat sink calculator. 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. 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. How does the heat sink calculator work.

Or select a value from our material database. Heat sink thermal resistance delta t for each component part of the heat sink. The equation should be. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters.

Enter the thermal conductivity of your material w m k. A reference link has been placed below the calculator for further reading. 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. In our experience it generally estimates the overall heat sink volume within 15 of a final design.

Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects. Input the cross sectional area m 2 add your materials thickness m enter the hot side temperature c enter the cold side temperature c. The heat transfer conduction calculator below is simple to use. How does the heat transfer conduction calculator works.

Multiple heat sources attached to the heat sink can be evaluated. The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink. 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.
