| Abstract: | With varied thermopile number n and varied dimensionless current j,the performance of a two-stage thermoelectric cooler was analyzed under different hot-side temperature.The parameters of n and j were then optimized through analysing the expression of maximum temperature difference between hot-side and cool-side,net cooling capacity,and refrigeration coefficient,under different hot-side temperature conditions.The corresponding optimal ranges of n and j were given out. |

| Keywords: | two-stage thermoelectric refrigerator hot side temperature refrigeration coefficient cooling capacity |
