Abstract ：We describe a single level quantum dot driven by an external stochastic force which works as a nano-thermoelectric refrigerator. Based on the model, expressions for the cooling rate, power input, and coefficient of performance (COP) are derived. The effects of the energy level and energy space on the refrigerator are revealed. The optimal performance characteristics are analyzed by numerical calculation. Furthermore, the practical operating regions of the refrigerator are determined.
