Optimized Design And Experimental Research Of J-T Cryocooler

J-T Cooling is one of the main cooling methods for cooling military infrared chips. This kind of cooler has been widely used in the infrared seeking system of air-bome optical radar,nightvision and missile infrared guiding. In this paper,first we gave a brief introduction about cryogenics,research and development of J-T cryocooler. Then we emphasis on the principle and system of J-T cryocooler,especially the design process of the cryocooler. The optimal design concepts and realization process were systematically introduced. Combining with the optimal design process of the representative Su-xx optical radar the feasibility and practicality of this system theory was proved.. The system development may help researchers to optimize structure specifications of J-T cryocooler in practice and make the development period shorter. Finally scientifically modernized the process.
