The hybrid cooler on the basis of extruded samples Bi_(85)Sb_(15) solid solutions

摘要

It has been developed hybrid cooler, consists of two blocks, and operating on the basis of Peltier and magneto-Peltier effects. The first block, operating on the basis of Peltier effects consists of four stage with 24 W power supply and 250 mW cold productivity, and second block - of one cascade of one thermoelement, operating on the basis of magneto-Peltier effects in a magnetic field (～ 0,3 T). It hase been shown, that at use of the specified materials temperature of the heat-adsorbing surface of the hybrid cooler falls up to 150 K. Designed hybrid cooler with ～24,5 W power supply and 20 mW cold productivity can be applied to cooling elements with ～15-20 mW thermal loading.
