At the CEC/ICMC 2025 Conference, held in the United States from May 18 to 22, Dr.Prof. Wei Dai, Chief Scientist of Lihan Cryogenics and professor at the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, was awarded a Fellow of the Cryogenic Society of America (CSA) in recognition of his outstanding contributions to the field of cryogenics. Haibing Li, General Manager of Lihan Cryogenics, attended the conference and accepted the award on behalf of Prof. Dai.
 

The Cryogenic Society of America (CSA) is one of the world’s leading organizations dedicated to cryogenic science and engineering, with members from 47 countries. Since 2000, the CSA Fellow has been awarded about once every two years, with only one or two individuals selected each time. Fellows are chosen based on their sustained and exceptional contributions to the field of cryogenics.With this year’s selection, only 19 individuals worldwide have received the honor-and Prof. Dai is the first Chinese scholar to be awarded.
 

Official Citation From CSA:
Dr. Prof. Wei Dai is recognized for his outstanding and sustained contributions to cryogenics, particularly in the development of electrically /thermoacoustically-driven pulse tube coolers, sub-Kelvin refrigeration technologies and in the related fundamental research. He has led cutting-edge cooler research at the Chinese Academy of Sciences, producing high-efficiency systems and innovations. The research on the pulse tube cooler has also translated into numerous industry applications through the collaboration with Lihan Cryogenics. In addition to his technical achievements, he has shown strong commitment to the cryogenics community through mentorship, international collaboration, and active roles in major conferences.
