Reliability control of a thermoelectric cooler with changes in ambient temperature

The paper presents the development of method thermoelectric system reliability indexes control for providing thermal modesof radio electronic equipment, based on coolers medium temperature variation. A mathematical model investigating influence environment variation performance a single-cascade cooler at given level cooling, load, geometry thermoelement branches different characteristiccurrent operating modes is considered. results calculations basic parameters, indices, dynamic characteristicsand analysis dependences are revealing peculiarities processes. It shown that decreasing chiller design decreases current, increases cold-productivity, and time reaching steady-state mode various characteristic current modes. to operation from minimum failure rate maximum cooling capacity fixed temperature. ensured in mode. Reduction such significant indices as amountof consumed energy modes, required heat dissipation radiator, noted. Analysis research has it possible indicators single-stage by changing value current. change due an external supporting device makes vary find compromise between reliability, dynamics support system.
