Heat Sink Design Tool

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.

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. Analysis demonstrated that the design with heat pipes running above the components kept junction temperatures within 2 c of the original. One with heat pipes that stopped at the edge of the components and the other with heat pipes that ran above the components. Simple but powerful tool for designing and selecting heat sinks.

Heat sink design goals may vary but in this report optimization of the vertical heat sink is the main objective. Sign up now. Heat sink designer is a product of mechanical solutions a industry respected thermal consulting firm since 1991. In this article we ll walk you through the basics of heat sinks and heat sink design including the calculations involved in defining the proper heat sink for your application.

Heat sink simulation tool. 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. 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. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance.

Based on this definition anything from a rectangular sheet of metal to a complex finned copper or aluminum extrusion can be used as a heat sink. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. In this report both parts are considered separately. 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.

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. Ats engineers used analytical modeling and cfd simulations to examine the thermal performance of two aluminum heat sink designs. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. The user can choose between natural or forced convection and or radiation for the modes of heat transfer.

Cooling management with thermal analysis. 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. 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.
