True liquid cooling? In a phone?

The latest concept showcase from OnePlus took one of our favourite PC technologies, and fitted it inside a conceptual handset that resembles the OnePlus 11.

Unveiled at MWC 2023, OnePlus called the technology Active CryoFlux and claimed it can reduce the phone's temperature by up to 2.1°c while gaming. This purportedly raises the phone's performance by 3-4FPS (frames per second).

OnePlus said it also help to keep the phone cooler while charging, reducing temperatures by 1.6°c. Thanks to this, the phone can charge up to 30-45 seconds faster.

It's not a lot, but gains are gains -- especially when you consider how small a smartphone is (relative to a liquid-cooled DIY PC) and the physics and engineering need to shrink a true water-cooling system down to size.

OnePlus says that an “industrial-grade piezoelectric ceramic micropump” circulates liquid throughout these glowing pipelines.

There were no details on how they could squeeze the whole thing into less than 0.2cm² of space. Did some other components have to be sacrificed or resized? That would have been interesting to know.

Of course, the system had to include futuristic lighting, because OnePlus wanted its fans to think about its fancy tech knocking about in such a tiny body. But the lighting isn’t just for show – the tubes are illuminated to represent exactly where the glowing blue liquid flows.

Unfortunately, as a conceptual phone feature, there’s no word on whether this Active Cryoflux tech will ever hit the streets. We’ll have to be content with accessories like the ROG Phone’s clip-on AeroActive cooler to keep our fingers cool and comfy during long mobile gaming sessions.
