Aiming at urgent need of temperature regulation for the cockpit of armor vehicles

temperature modulating devices for large space based on semiconductor refrigeration are tested.The large space test chamber

semiconductor refrigeration system and temperature monitoring system based on distributed temperature sensors are designed.Different types of cooling plate

which work in different currents working condition and heat radiation conditions

and then the data that reflects the variation of temperature difference between the cold junction and hot junction and the average temperature in the test chamber is got.The results show that the temperature monitoring system can collect and display the temperature of the monitoring point

the cooling plate and its work current should accord with the intensity of heat radiation of refrigeration system to achieve good cooling effect

and the adequate enhancement of the scattered cold ability at cold junction helps to reduce the temperature difference between cold junction and hot junction and improve the cooling effect.
