U.S. researchers invent portable cooling devices in the future or can go out with air conditioners

[China Instrument Network Instrument Research and Development] On September 17, according to foreign media reports, US researchers recently invented a solid-state cooling instrument that can be made into a small refrigerator, carried in a pocket, and used for mobile phones, computers, and wearables. Electronic products and other effective cooling, to extend their useful life.

The researchers pointed out that with this technology, people can wear cold cooling bandages instead of ice packs in the wound in the future, small air conditioning and thermal management systems can be placed on the desk or integrated into the seat for local temperature control.

The research project leader, Qi Qibing, a professor at the University of California, Los Angeles, pointed out that the research team used polymer materials to create a thin film that can convert electrical and thermal energy. The film's cooling power per gram is as high as 2.8 watts, and the coefficient of performance exceeds that of existing vapor compression refrigeration technology, which means that the same amount of heat will be used to transfer less energy.

He said tests have shown that the temperature-reducing instrument made with this technology has reduced the temperature of a Samsung smartphone battery by eight degrees Celsius in five seconds. In contrast, air cooling technology only reduces three degrees Celsius in 50 seconds.

He said: "It can be used to make a small refrigerator, carry it in a pocket, adjust the temperature of different parts of the body according to individual needs, and consumes little power. It can also give mobile phones, computers and wearable electronic products, etc. Effectively reduce the temperature and extend their useful life."
