In order to improve the battlefield survivability of the targets, the electro-thermal technology was applied in the infrared dynamic camouflage of the targets. Reducing the power consumption is one of the key technologies of the electro-thermal camouflage. By analyzing the composition and basic unit structure of infrared dynamic camouflage system, the thermal conduction model at each working level of the basic unit was established. Then the driving power of the thermo electric cooler and the fans active heat dissipation was calculated. The influence of temperature difference setting and ambient wind speed on power consumption was analyzed with simulation calculation. The results can provide theoretical reference for the demonstration, design and optimization of the power consumption index of the infrared dynamic camouflage system.
