Heat Sink Simulation Tool

Cooling Management with Thermal Analysis

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.


Heat sinks have long been used when it comes to the cooling of electronic components in order to maintain them under the maximum allowed operating temperature. Thermal management for these electronic components raises several challenges for heat sink designers and engineers. The challenges can be related to the heat sink material such as thermal resistance and conductivity. One example is the decision of whether to use pin fin, staggered or flared heat sink for specific cooling requirements. To asses their cooling efficiency, the classical approach of Design – Build – Test – Redesign is time-consuming and expensive. Designers are now turning to an effective method to virtually evaluate, test and optimize designs for maximum cooling efficiency before they are build, saving production time and cost. Thermal simulations is the computerized method to study the heat dissipation efficiency of a heat sink both in conceptual and detailed design stages. SimScale allows engineers to quickly analyze the heat sink design for thermal resistance and conductivity. Moreover, they can also compare various types that may include active, passive, stamped, single fin, forged and more.

Thermal Resistance

Determine the required air flow around a heat sink to enhance the thermal resistance for satisfying components’ thermal criteria.

Thermal Conductivity

Using SimScale, you can compare the performance of a heat sink with different materials to ensure better thermal conductivity for faster cooling.

Energy Efficiency

Energy efficiency is essential for an environment-friendly product. SimScale CAE enables you to compare different design versions to obtain better results.

Cooling Management

Ensure proper cooling of the design and determine if the ventilation is sufficient to safeguard and protect the components from overheating.

Heat Dissipation

Decide whether passive cooling is sufficient to safeguard and protect the components from overheating or active cooling is required.

Thermal Management

Studying heat transfer in solids (FEA), fluids (CFD) and the interaction between them (CHT) is necessary in thermal management processes.



Heat Sink LED Packages Simulation

Studying the heat sink cooling performance for different LED packages

This heat transfer analysis was performed on 3 different Light Emitting Diode (LED) packages used in consumer electronics. The focus of this simulation was to evaluate the cooling performance for different LEDs array placement. The highest temperature for the LED packages were compared with experimental data and the results showed that the heat sink design needs to be optimized.

Conjugate Heat Transfer Analysis on a Raspberry Pi

Thermal Analysis of a Raspberry Pi Heat Sink under Passive Cooling Environment

This conjugate heat transfer analysis is performed on a Raspberry Pi enclosure having a processor with a mounted heat sink over it. The focus of this simulation is to study the cooling performance to determine if it meets the cooling requirement of the Raspberry Pi. This study clearly shows that the cooling is still quite effective under passive environment with the use of designated heat sink.

I have used a lot of simulation packages over the past 25 years, including Nastran, Ansys, SolidWorks, and a whole host of others. I have been using SimScale for about nine months now and it has become my goto simulation tool. It allows me to run models larger than I have ever conceived on my own workstation.
