Heat Sink Design Calculator

Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.

Heat sink design calculator.

The thermal resistance of the heat sink and temperature of the power source is calculated. 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. Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions.

Heat transfer design and engineering. As with the natural convection heat sink calculations the radiation heat dissipation q r1 from the area a 1 is calculated using equation 9. A reference link has been placed below the calculator for further reading. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance.

However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow. Heat sink convection with fins calculator. How does the heat sink calculator work. Heat transfer by convection of a heat sink with fins calculator and equations.

The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. The variables ε is the surface emissivity 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. Heat sink thermal resistance delta t for each component part of the heat sink.

This heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base.
