A Design of Thermoelectric Cooler and Optimization

Design, analysis and optimization of a thermoelectric refrigerator was carried out in this work the systems use thermoelectric "peltier" refrigerators (thermoelectric modules) to produce cooling or heating. The design calculation are find the performance curve of the thermoelectric module with the purpose of is find by simulation. Simulation results were compared with the practical data. The system simulation shows that exist a cheapest heat sink used for the thermoelectric refrigerator. the thermoelectric refrigerator with an air-cooled heat sink with thermal resistance 0.2515°C/W. Comparison was done between Bismuth telluride (Bi2Te3) and Antimony telluride(Sb2Te3) for the thermoelectric module. It was found that the bismuth telluride (Bi2Te3) due to its low thermal conductivity and high See back coefficient at room temperature has higher figure of merit (Z) and thus performed better as compared to Antimony telluride. The design be capable of be ready either on basis of the highest value of the cooling capacity, or on the basis of the most excellent heat sink technology existing.
