xMEMS, a leading innovator in MEMS technology, has unveiled its groundbreaking XMC-2400 µCooling (microcooling) chip. This state-of-the-art chip, inspired by the thinness and efficiency of solid-state speaker drivers, aims to revolutionize cooling systems in extremely slim devices like smartphones and tablets. By actively cooling these devices, xMEMS' microcooling chip addresses overheating concerns and ensures enhanced performance.

The XMC-2400 chip is a mere 1mm tall and is built on the same MEMS technology that powers xMEMS' upcoming ultrasonic driver technology for headphones. This cutting-edge microcooling chip has the potential to introduce sleeker and more heat-resistant gadgets, guaranteeing improved sustained performance.

Imagine a fanless MacBook Air or gaming controller packed with xMEMS' XMC-2400 chips. Such devices would remain cool even under extreme conditions, offering users a seamless and uninterrupted experience. Tablets would also benefit from this technology, delivering enhanced speed and performance even during intensive tasks.

xMEMS' solid-state drivers, exemplified in products like Creative's Aurvana Ace, have already proven their ability to reproduce mid- and high-range frequencies with remarkable precision. The company's next-generation solid-state driver, known as Cypress, offers exceptional sound across all frequency ranges. These same air-pushing capabilities have been harnessed in the new microcooling chip.

According to Mike Housholder, Vice President of Marketing and Business Development at xMEMS, the XMC-2400 chip utilizes ultrasonic modulation to generate pressure pulses for air movement. Weighing less than 150 milligrams, this chip can move an impressive 39 cubic centimeters of air per second while withstanding 1,000 Pascals of back pressure. Thanks to its solid-state design, the XMC-2400 chip eliminates the need for traditional moving parts, such as rotors and fins, ensuring durability and longevity. Its compact form enables easy placement directly on top of heat-generating components like APUs and GPUs. Additionally, the chip boasts an IP58 rating, making it resistant to dust and water damage.

While xMEMS is not the only company exploring solid-state cooling technology, its XMC-2400 chip offers a distinct advantage. Competitors like Frore's AirJet Mini and Mini Slim can generate similar back pressure but are bulkier, measuring 2.8mm and 2.5mm thick, respectively. Frore demonstrated its technology by incorporating it into a MacBook Air, resulting in enhanced sustained performance. However, xMEMS' chip surpasses them in thickness, flexibility, and ventilation options, making it the preferred choice for manufacturers.

Housholder anticipates that the XMC-2400 chip will have a price tag of under $10 per unit. By the end of the year, xMEMS plans to distribute the chip to four or five existing partners, with other manufacturers gaining access in the first quarter of 2025. The fabrication partners, TSMC and Bosch, can easily transition from producing speakers to manufacturing microcooling chips without the need for equipment or production line modifications.

As devices like the iPad Pro continue to prioritize slimness without compromising on performance, the demand for ultra-thin cooling solutions becomes evident. The xMEMS microcooling chip offers a glimmer of hope, potentially becoming an indispensable component in future devices. Although further testing and real-world applications are necessary to provide a comprehensive assessment, xMEMS' microcooling chip paves the way for improved thermal management and optimized performance in thin gadgets.
