Next-generation Peltier cooling technology
Peltier devices achieve cooling via the Peltier effect, in which applying an electric current to a semiconductor causes one side to cool and the other to heat. As it requires no refrigerants, this method is gaining traction as a next-generation alternative to refrigerants that offer a lower-impact solution.
The thin-film Peltier refrigerator surpasses the cooling efficiency of traditional vapor compression refrigerators, creating the potential for the commercialization of next-generation refrigerators without refrigerants. Peltier cooling enables fast and precise temperature control with a simple configuration, making it applicable to various industrial fields, including home appliances, semiconductors, medical devices, automotive electronics, and data centers.
Samsung and the APL research teams have achieved superior cooling efficiency in Peltier semiconductor devices by improving the efficiency of Peltier devices by nearly 75% through the use of new thin-film semiconductor materials as well as miniaturization and lightweight design.
The newly developed Peltier device demonstrated significant advantages in terms of resource efficiency and mass production. The research team confirmed that the new manufacturing process not only drastically reduced the amount of Peltier materials required down to about 1/1,000 of the material typically required but also simplified the production steps.
