Applied Research on Infrared Camouflage Based on Heat Pipe Temperature Control Technology

为实现针对高温机动目标的红外伪装难题,试图利用热管温控组件设计高效导热散热结构,以降低机车发动机排气管的温度而实现红外伪装。首先进行了热管传热的理论计算,在此基础上建立了高温排气管热管温控红外抑制结构模型,并且搭建了模拟验证试验装置,试验结果表明采用热管温控结构可使发动机排气管的热抑制效能达到62.9%,具有明显的红外伪装效果。

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.
