International ClassF25B 021/02Foreign Application Priority Data1992-11-05 SUAbstractA method of cooling an object with a thermoelectric battery cascade which is based on carrying heat from the object and further from stage to stage with an adjustable regulated direct current applied to the terminals of the battery until a steady-state operation mode is obtained corresponding to the required temperature of the object being cooled. In accordance with the invention transfer of heat removed from the object is effected successively in time in portions from stage to stage with intermediate heat storage on heat accumulators. In order to effect this, the operation of each stage is carried out in active heat removal and thermal switch modes, wherein the duration of the time intervals and values of currents flowing through the stages of the thermobattery for those modes is adjusted in the process of bringing it to the steady-state mode of operation with required values of temperatures of the object being cooled and heat accumulators and with minimum value of electric power consumption. In accordance with the invention the number of thermopiles in all of the battery stages is taken to be identical, due to which substantial reduction of the consumption of scarce expensive semiconductor thermoelectric materials is attained, and this means a reduction in the specific costs of the thermoelectric battery.Other References
