AirJet ultrasonic cooler for mobile processors

AirJet – ultrasonic cooler for mobile processors

Frore Systems has introduced AirJet, a fanless active cooling system for laptops, tablets and handheld consoles, which in the future can also be used in smartphones, virtual reality headsets, desktop computers and even data centers. Instead of a fan, air is blown in by ultrasonic vibrations of special membranes – jet engines on aircraft are cooled in the same way.

AirJet is a compact rectangular block that is installed on top of the processor, chipset or other heating element. The device offers mobile computer designs with minimal thickness and silent operation and promises a small revolution in this segment. A stream of air is used for cooling, only it is not pumped by rotating fan blades, but by membranes vibrating at ultrasonic frequency. The technology is based on the well-known effect of jet leakage in aviation, which is used in the cooling of jet engines.

Air is drawn in through slots on the top of the AirJet block, directed to the processor, absorbing heat from it, and expelled through the back of the computer. The thickness of the block is 2.8mm, which is almost half the thickness of typical laptop fans, which is 5mm. At the same time, AirJet offers a pressure more than 10 times higher: 1750 Pa versus 140 Pa. Frore also claims that the smaller AirJets dissipate heat better, so computers can’t limit their performance to avoid overheating.

The developer calls these cooling units “chips” – they do not contain any computing components, but similar technologies are used in production. The first generation systems are available in two versions: the AirJet Mini, which is slightly smaller than a business card (28x42mm, 5.25W power) and is intended for mid-range tablets and laptops, and the larger AirJet Pro (32x72mm, 5 .25W output) 10.5W) for high performance laptops. Four Mini-type units can handle a 13-inch Arm-based laptop, while three Pro-type units can handle a more powerful 15-inch model.

The first generation AirJets have some limitations so far: three or four units can cool a computer with a processor with a TDP of up to 28 watts, but they still won’t pull a gaming laptop with 100 watts of discrete graphics. Maybe this problem will be solved in future AirJet models, the very first generation is supposed to make mobile computers even thinner. AirJet coolers consume up to 1.75 W, weigh up to 22 g and generate no more than 24 dB of noise.

Prices for the AirJet Mini or AirJet Pro have not yet been announced, but it is known that they will be launched in the first quarter of next year. Frore added that they have already enlisted the support of Qualcomm and Intel – and work is already underway to integrate new systems into the Intel Evo platform.
