Abstract: In order to solve the design problem of semiconductor refrigerators with large space, the semiconductor refrigeration system and temperature monitoring system were designed. The distributed temperature sensors based on DS18B20 were used to realize the function of intelligent control and modulation. The data condition that reflects the variation of temperature difference between the cold junction and hot junction and the average temperature in the test chamber were got. The test results show that temperature monitoring system have the traits of real-time measuring and accurate controlling. It provides data evidence for analyzing the performance of thermoelectric cooling chip and lays the foundations of theory and experiment for researching and designing the semiconductor refrigerator for the cockpit of armor vehicles.
