This paper firstly introduces the principle of thermoelectric cooler. Based on Peltier effect, when the current passes through the thermoelectric leg, the carriers in the material will bring heat and move from one side to the other side, which would lead to the phenomenon of cooling. Thermoelectric cooler has many advantages, such as no noise, no pollution, cooling rapidly, simple operation, strong reliability and accurate temperature control. With the miniaturization development of power electronics and higher demand of sensitivity for infrared detection, it is required to fabricate smaller and better thermoelectric cooler. Thus, the study of miniaturization of thermoelectric cooler has attracted many attentions in recent years. Then the paper describes the applications of thermoelectric cooler in the fields of power electronics, military, space exploration, commercial and scientific research. Thermoelectric cooler can realize the temperature control for power electronic devices, instruments and so on. At last, the key problems of thermoelectric cooler and the development directions are summarized, which provides an idea for the further study of thermoelectric cooler.
