Frore Unveils Waterproof AirJet Mini Sport for Smartphones

Author: AnandTech

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.”
