Cooling significantly impacts the performance and longevity of various products, including batteries, electronic devices, and motors. In fact, it is estimated that by 2030 approximately 6% of the world's total energy consumption will be dedicated to cooling electronic devices. Consequently, there is a pressing need to introduce more efficient cooling solutions to the market.
Apheros has developed an innovative metal foam that stands out for its exceptional heat dissipation capabilities thanks to its unique structure. This groundbreaking technology allows for an impressive five-fold increase in passive air cooling while weighing only a third of existing solutions.
The outstanding performance of Apheros' metal foam is achieved through an innovative manufacturing process that produces open-pore structures with a surface area a thousand time greater than conventional metal foams. This increased surface area not only enhances cooling but also creates exciting possibilities for various applications, for instance substrates for catalysis. The open-pore structure facilitates wetting and infiltration, making Apheros’ foams the perfect fit for applications such as grease reservoirs in drills and gears.


The team at ETHZ has demonstrated the strong mechanical and thermal properties of Apheros’ metal foams as well as an open-pore structure and exceptional wetting. This project will enable proof of concept studies in thermal management and lubrication to validate our technology with customers, test long term reliability and performance, and set-up market entry. It will also support the upscaling of Apheros’ production from lab-scale (30 parts/month) to more than 300 parts/month, allowing us to meet our customers’ demands.
