Heat Sink Design Tool

Aavid genie is a streamlined interface of our aavid smartcfd thermal simulation software for users to try out different heat sink configurations use multiple heat sources.

Heat sink design tool.

This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. Heat sink designer is a product of mechanical solutions a industry respected thermal consulting firm since 1991. Heat sink design goals may vary but in this report optimization of the vertical heat sink is the main objective. A heat sink is a part that conducts heat from a heat generating component to a larger surface area to dissipate the heat to the surroundings thus reducing the temperature of the component.

The user can choose between natural or forced convection and or radiation for the modes of heat transfer. Heat transfer from the heat sink consists of radiation and convection from both the intra fin passages and the unshielded surfaces of two outer fins. Simple but powerful tool for designing and selecting heat sinks. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.

In our example of proper heat sink design we ll use the common l298 multiwatt15 full bridge driver as this chip can get very hot when operating at the upper limit. Sign up now. In this report both parts are considered separately. The simulation results aid in reducing design time and increasing the reliability of the finished heat sink product all before the first prototype is even built.

Cooling management with thermal analysis. One with heat pipes that stopped at the edge of the components and the other with heat pipes that ran above the components. Download a free trial now. Analysis demonstrated that the design with heat pipes running above the components kept junction temperatures within 2 c of the original.

Ats engineers used analytical modeling and cfd simulations to examine the thermal performance of two aluminum heat sink designs. Aavid genie is an online heat sink design tool that allows for rapid thermal modeling and comparison of multiple heat sink constructions and manufacturable heat sink design. Heat sink simulation tool. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance.

Simscale is a 100 cloud based cae software for heat sink design simulation that lets you test validate and optimize your designs through cfd fea and thermal analysis. R tools is a no charge on line simulation software that allows users to model the optimum air cooled heat sink solution tailored to their project requirements. The thermal resistance of the heat sink and temperature of the power source is calculated.
