What is a quiet ``solid state active cooling'' that cools the CPU and GPU more than a conventional fan even though it is a card size?
In order to discharge the heat that is inevitable when running a computer, computers are equipped with an air-cooling system that turns a large fan to lower the temperature, and a water-cooling system that lowers the temperature by running a pipe around it and passing a coolant through it. increase. American startup Frore Systems has developed ` ` Solid State Active Cooling '' , a palm-sized technology that is quieter and more efficient than before, and will be held from May 30 to June 2, 2023. It was released at

The new cooling technology 'Solid State Active Cooling' developed by Frere Systems can be seen in the following movie.

This is 'AirJet Mini' which put solid state active cooling into practical use. The size is 41.5 mm long x 27.5 mm wide x 2.8 mm, which is slightly larger than the SD card. According to Frore Systems, it delivers higher air pressure than traditional fans while reducing noise and doubling cooling performance.
There is also an AirJet Pro (left) that has the performance of two AirJet Minis (right).
Solid-state active cooling features a special internal membrane that vibrates at ultrasonic frequencies to create airflow that passes through a heat spreader at the base, picks up heat, and exhausts it. Frore Systems does not disclose the specific technology as a 'trade secret', but the special membrane resonates with what it calls 'structural resonance' and is devised to generate maximum vibration with minimum power. It seems that there is
Intake air from the four slits on the top of the AirJet Mini and exhaust from the sides.
According to Frore Systems, the AirJet Mini has an operating power of 1W and exhausts the equivalent of 5.25W of heat. The strength of the airflow is quite strong, and at the COMPUTEX TAIPEI 2023 booth, a demonstration was exhibited that floated a ping-pong ball with the exhaust of AirJet Pro.
According to Frore Systems, the AirJet Mini and AirJet Pro are capable of pumping air at 10 times more pressure than typical laptop fans, and the operating noise level is below 21-24dBA. matter. This noise level of 21 to 24dBA is about
Also, laptops with a fan on the bottom tend to trap heat when placed on a bed or carpet. Frore Systems says that it can solve the problem of exhaust heat from the notebook PC depending on where it is placed.
However, it is unknown how high the manufacturing cost of AirJet Mini and AirJet Pro that put solid-state active cooling to practical use is. “We are partnering with multiple OEMs and expect to see products on the market in 2023,” said Frore Systems. In addition, semiconductor maker Intel is helping to bring solid-state active cooling to market.
