摘　　要：针对坦克车体红外辐射特征过于明显的问题,对温差发电技术用于坦克红外抑制的原理进行了分析,并应用在坦克排烟管表面进行不同转速条件下的试验测试,结果表明:温差发电器件能够输出足够的电能驱动风扇工作,经热电转换、风扇和散热器联合散热后,散热器外表温度较排烟管表面温度下降超过65.0%;发动机转速增加导致排烟管温度升高,从而引起温差发电器件冷热面温差的增大,驱动风扇的输出电压增大,对流换热增强,散热器外表温度降低更明显。Aiming at the fact that too much infrared radiation is generated by the tank′s body,the theory of applying thermoelectric generation technology to tank infrared restraint was analyzed,then thermoelectric generation technology was applied to tank′s drainpipe surface.Experimental tests were done at different revolving speeds.The results show that thermoelectric generators can produce sufficient electric power to drive fan.And the external surface temperature of the radiator is reduced by over 65.0% compared to the drainpipe′s temperature when combining the fan cooling and heat radiation;When the drainpipe′s temperature which is caused by engine′s revolving speed rises,the temperature difference of thermoelectric generators′ cold and hot sides increases.Then the outport voltage which is used to drive the fan rises,and heat transfer convection is enhanced,which causes radiator surface temperature to decrease more obviously.
