Heat Sink Design 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 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. This heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. The variables ε is the surface emissivity of the heat sink.
Heat sink thermal resistance delta t for each component part of the heat sink. In our experience it generally estimates the overall heat sink volume within 15 of a final design. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow.
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. How does the heat sink calculator work. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance.
