Frore Systems unveiled its new AirJet Mini Slim at CES 2024 this week, a thinner and lighter version of its existing cooling solution that follows what the company calls “Frore’s Law.”
Frore’s Law, a playful reference to Moore’s Law, is a promise to double the company’s cooling performance every two years without changing the Z-height. Or, the company could shrink the height of its AirJet cooling solution, while keeping its cooling performance the same.
The second option is what Frore did with the AirJet Mini Slim, which can produce the same 1750 pascals of air pressure at only 21 dBA of noise while reducing its thickness from 2.8mm to 2.5mm. The weight has also been cut down to just 8 grams.
Frore’s new cooling solution has a clever self-cleaning feature, which is similar to how a ShopVac works. The Mini Slim can switch its airflow and blow air out from its input filters, a feature that can be set to happen at regular intervals.
It also has a thermal sensor, which can trigger the cooling solution to turn on at a certain temperature without needing another microcontroller or CPU to control it.
The cooling capabilities of the Frore’s AirJet Mini Slim are the same as before: 5.25W. This means that the company’s MEMS membrane moves air heated from a laptop’s CPU or other parts by vibrating.
It cools down enough heat at 25 degrees, which lets the chip run at an extra 5.25W of power in the same thermal limit. This improves the laptop’s performance, as PCWorld reported earlier on Frore.
At its booth, Frore displayed examples of everything from Apple MacBooks to SSDs that used the Frore Airjet instead of a conventional heat sink. How does “Frore’s Law” work? According to Frore engineers at the company’s booth, it’s quite simple.
Frore’s MEMS-activated membrane creates suction by vibrating and the company can increase it by adding more membranes, making the membrane bigger, making the vibration stronger, or by doing all of them together.
Also, the company’s first AirJet chips had enough engineering flexibility that it can keep shrinking the z-height or thickness, they said.
Frore executives said that the company has drawn a line between the cooling performance and thickness of its AirJet chips.
