Heat Sink Design Calculator

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. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. How does the heat sink calculator work. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance.
Heat sink thermal resistance delta t for each component part of the heat sink. The user can choose between natural or forced convection and or radiation for the modes of heat transfer. Heat transfer design and engineering. The variables ε is the surface emissivity of the heat sink.
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. Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions. A reference link has been placed below the calculator for further reading.
Heat sink convection with fins calculator. 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 transfer by convection of a heat sink with fins calculator and equations. Advanced tool to calculate thermal resistance pressure drop and base temperature of plate fin heat sinks with flow bypass and base spreading effects.
The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.
