The First Active Liquid Cooling For Smartphones
This goes beyond some vapor chambers that are sometimes referred to as “liquid cooling”. This solution actually is an active cooling system capable of handling way more heat than passive solutions. REDMAGIC did a good job of miniaturizing the components in the system. It built a piezoelectric ceramic micropump, which is the heart of the system. Multiple design iterations were needed before finding a good balance.
The brand used micron-level laser cutting to carve channels that carry the liquid between the pump and the fan. Channel membranes were designed for smooth, low-resistance flow. The liquid being pumped is an anti-freeze coolant. It remains effective between -40°C and 70°C. This liquid is used in AI servers, and it has excellent electrical insulation and heat transfer.
There were other challenges in developing a valid solution. The company also had to make this solution durable enough to withstand… drops. Yeah, while the chances of dropping a PC are minimal, this happens very often with smartphones.
REDMAGIC’s work has an ultra-low temperature bonding process and new anti-puncture membranes to ensure the phone can survive a hit. In fact, it went through multiple drop tests to determine its durability.
It’s Ready to Launch with Redmagic 11 Pro Series
The new models will come with the Turbo Fan 4.0 system. It has three core air-cooling approaches: independent, channel-based, and composite. It includes an active cooling fan, which can spin at up to 24,000 rpm. This fan comes with a large airflow duct and a dual-track heat dissipation system.
