Since the size of electronic components keeps on decreasing, the need for improved heat dissipation on these components keeps increasing. This dichotomy presents thermal engineers with a formidable challenge: how to design smaller coolers that dissipate more heat. Adding to the challenge, the fast-paced evolution of electronics means that the development time for the new cooler designs is shorter and shorter. This publication explores the combination of generative design and advanced two-phase cooling simulation techniques to efficiently create two-phase electronics cooling devices.


  • Generative design can be used to design a two-phase evaporator cooling system with minimal human input or interaction.
  • A fully three-dimensional solid and fluid domain model, and an advanced interface heat transfer model based on a two-phase multiplier concept are presented.
  • A case study demonstrated that the cooling can be improved up to 15% without affecting pressure drop, manufacturing or cost of the device.
