Over the past couple of years, Frore Systems has demonstrated several ways that its AirJet solid-state active cooling systems can be used to improve cooling in fanless devices like laptops, tablets, SSDs, and edge computing devices. But there are a subset of those applications that need their cooling options to also be waterproof, and Frore is looking to address those as well. To that end, this week Frore introduced its AirJet Mini Sport, a waterproof, IP68-rated solid-state cooling device that is aimed at use in smartphones and action cameras.

Introduced at MWC Shanghai to attract attention of China-based handset vendors, edge and industrial computing devices, and action cameras, the AirJet Mini Sport is an enhanced version of Frore's AirJet Mini Slim. This version has been fully waterproofed, offering IP68-level protection that allows it to work while being submerged in over 1.5 meters of water for up to 30 minutes. Internally, the AirJet Mini Sport can effectively dissipate 5.25 Watts of heat by generating 1750 Pascals of back pressure, while consuming 1 Watt of energy itself.

Elsewhere, Frore claims that the AirJet Mini Sport can be used to provide 2.5 Watts of cooling capacity to smartphones. Which, although not enough to cover the complete power consumption/heat dissipation of a high-end SoC, would have a significant impact on both burst and steady-state performance by allowing those chips to run at peak clocks and power for longer periods of time.

To ensure consistent performance of Frore's AirJet Mini Sport in diverse environments, the cooling device includes features such as dust resistance and self-cleaning. In addition, just like AirJet Mini Slim, the Sport-badged version its own thermal sensor to control its own operation and maintain optimal performance. As a result, Frore claims that smartphones and action cameras with the AirJet Mini Sport can achieve up to 80% better performance.

"We are excited to announce the waterproof AirJet Mini Sport," said Dr. Seshu Madhavapeddy, founder and CEO of Frore Systems. "Consumers demand increased performance in compact devices they can use anywhere, on land or in water. AirJet unleashes device performance, now enabling users to do more with their IP68 dustproof and waterproof devices."

    If the smartphone requires an enlarged camera bulge, then it would be nice if the maker enlarge the battery. Reply

    Yeah, just make the whole thing thicker and more ergonomic instead of having any silly hump at all. Reply

    I totally agree with you. Just maklethe whole thing thicker. I really don't like the camera bumps we already have today.
    I do wonder with the rate at which manufacturing is moving to new advance process nodes will we need them below 2nm

    Also make them out of grippier material. Half the reason why my phones are cased is because leather is easier to hold onto than glass or smoothly polished metal. Reply

    One thing that's important to point out, though, is that it can't cool under water.

    So while it is certified not to die unless you exeed the under water period and it will also eject the water that made it inside to recover from immersion, while it's inside, it's outside operational specs.

    I order to recover it evidently must be able to more (or even vaporize) the first droplets towards the exit and then work backward, but it's not exactly pumping water and might actually shut down while immersed to avoid damage.

    Not sure if salt crystals will count as dust, should you try this in the great outdoors.

    Could somebody else please go first?

    A shame, a compact low/moderate flow very low noise water pump wold be a really nice option for liquid cooling.

    Though I suppose this could be a case of "nope, can't pump water, definitely not, no silent pumping here, absolutely no big deliveries to General Dynamics Electric Boat, nope".

    Need edit so badly...


    In order to recover...

    Hey everyone! Check out my Super Sport Sport Utility Vehicle with Sport Steering, Sport Spoiler, and Sport Tyres!

    Really, slapping the word sport on something makes it faster, better, and more amazing-er as demonstrated by sport SUVs. Or at any rate, people are stupid enough not to question it and just assume the marketing injected into our brains that sport = good is not to be questioned.

    That rant aside, its interesting to see the ongoing development of the underlying technology even if the people behind said technology are absolute imbeciles when it comes to giving it a name.

    If the technology becomes as revolutionary as they claim (benefiting from further improvements, including node shrinks!), then it could become semi-ubiquitous in premium and thin devices. No consumer will need to know about the "Frore AirJet Mini Sport" name because it's a component sold to OEMs.

    The reviews of the Zotac i3-N300 box using these were not too kind. Hopefully it can be made to dissipate more heat after further revisions.

    I assume they called this one "sport" because people carry their phones in a sweaty pocket while they are doing a sport.
    so it's aptly named.
