全球首个全温区固态制冷材料发现，有望革新冰箱制冷技术

Core Insights - Researchers from the Institute of Metal Research, Chinese Academy of Sciences, have discovered a new cooling material called potassium hexafluorophosphate, which can achieve cooling effects across a temperature range from room temperature to near absolute zero, making it the only solid-state phase change cooling material effective across the entire temperature range [1] Group 1 - The new material exhibits a "full temperature range pressure card effect," allowing it to maintain cooling from room temperature to liquid nitrogen, liquid hydrogen, and even liquid helium by applying pressure [1] - This discovery opens new avenues for developing a new generation of efficient and environmentally friendly all-solid-state cooling technologies [1] - The findings have the potential to revolutionize the design concepts of refrigeration devices, such as refrigerators [1]
