A custom microchannel design that meets 3D printing manufacturing requirements requires a sophisticated solution. These problems limit the freedom to manufacture and design cooling/thermal management devices. Generative design through topology optimization, taking DfAM (Design for Addictive Manufacturing) rules into account, offers the solution.

Phase change is the process by which a substance changes from one state of matter to another. The most common phase changes include the transition from solid to liquid (melting), liquid to solid (freezing), liquid to gas (evaporation), and gas to liquid (condensation). The laws of thermodynamics govern these changes, which are caused by changes in temperature and pressure.

Simulating fluid flow and heat transfer phenomena with satisfying accuracy is an incredibly complex task generally achieved using CFD. ColdStream is not an exception to this rule and runs all simulations and optimizations through CFD calculations. But solving physical equations simultaneously for millions or even hundreds of millions of small discrete portions of space is a task of complexity well beyond what an average computer can do.

How does generative design of heat sink topology increase thermal performance? Imagine what it would be like to not be limited by your brain. We are all influenced by our education and life experiences, making our brain not only biased, but also limited. In heat sink design, this notion makes innovation harder than it needs to be.

Thermal design has always been a cornerstone for innovation. Today, that innovation has resulted in size conscious products that deliver more, faster, to maintain their competitive edge. This has resulted in more power being packed in today‘s smaller gadgets, which means that they generate more heat than their predecessors did. The increase in heat generation demands more robust and efficient cooling to ensure product reliability and efficiency.
