Abstract: A high efficient heat radiating structure with heat pipe is designed for an infrared camouflage of high temperature target. The temperature of engine exhaust pipe in a mobile equipment is decreased to achieve the infrared camouflage. The heat transfer of heat pipe is theoretically caculated at first, an inhibition model of high-temperature exhaust pipe is established based on the temperature control of heat pipe, and the experiment equipment is developed. The result shows that the heat inhibition effectiveness of temperature control construction of heat pipe can be up to 62.9%, and the effect of infrared camouflage is apparent.

Key words: optics, active target, infrared camouflage, heat pipe, high-temperature exhaust pipe
