Cooling systems have traditionally depended on fixed infrastructure such as power outlets, ventilation and refrigeration. Hissy, Durvag and UGREEN are building thermal management into portable products: a jacket, a drinks dispenser and a power bank. Each brings temperature control closer to the person using it.
Samsung-backed wearable brand Hissy has developed a jacket with an internal tubular Air Path connected to a CO₂ cartridge. The cartridge vaporizes liquid carbon dioxide to produce airflow that reaches the skin at -30°C. The system replaces batteries and fans with cartridges that can be changed in seconds, pairing a reusable garment with a replaceable cooling component.
Czech beverage startup Durvag has launched a portable, battery-powered keg system that chills and pours draft beer and other drinks without an electrical outlet. It brings refrigerated draft service to campsites, gardens, outdoor events and other locations without fixed bar infrastructure.
UGREEN has released a Qi2 magnetic power bank with a visible liquid-cooling loop. The system is designed to manage the heat generated during fast charging and reduce performance throttling inside the compact device. By exposing the cooling mechanism, UGREEN turns thermal management into a visible part of the product.
