TAIPEI (Taiwan News) — New Taipei–based Aewin is stepping up its sustainability push by introducing Taiwan’s first two-phase direct liquid cooling system, aiming to support kilowatt-class heat loads in AI servers.

Founded in 2000, Aewin traditionally focused on industrial computers and cybersecurity systems, per CNA. Spotting massive opportunities in cooling for the AI era, it has ramped up investment in next-generation cooling solutions.

In 2023, Aewin, alongside Industrial Technology Research Institute and other Taiwanese partners, developed kilowatt-class two-phase immersion cooling that submerges servers in coolant, evaporates heat, and cycles condensation to cut energy use. ITRI data suggests that if deployed worldwide, such systems could save 100 billion kWh of electricity annually and slash 50 million tonnes of carbon emissions.

Aewin went further at Computex this year, unveiling an upgraded two-phase immersion solution, capable of handling up to 100 kW of heat load. The system includes gas recovery and AI management features to predict server loads and adjust cooling.

“You simply can’t cool Nvidia’s newest GPUs with air,” Aewin CEO Lin Chang-an said (林章安). He said the strategy is to lead with technology rather than price, working with global partners to fine-tune cold plate specifications for client needs.

Expanding into cooling was not easy, Lin admitted, with worries that it might dilute Aewin’s core strengths. However, through cooperation with ITRI and other industry players, the company brought in external talent and filed multiple patents to secure a foothold.

Lin believes their two-phase direct liquid cooling will hit the market first, with manufacturers testing proof-of-concept systems. Immersion cooling designs are nearly finalized as well, with only final liquid testing left.

In the long term, Lin envisions developing servers tailor-made for two-phase immersion cooling. “This will take time and resources, but I think this step must be taken,” he added.
