摘　　要：针对船舶柴油机废气余热的特点,建立了空冷式柴油机废气余热驱动两级热电发电装置的有限时间热力学模型,获得了热阻分布和温度分布特征,在变温热源条件下,分析了热源参数、模块系数等对装置单位面积发电量、热电转换效率的影响。结果表明:对于350°C的柴油机废气,利用热电发电技术处理后下降约30℃/m,单位面积最大发电量为0.65k W。For the characteristics of waste gas heat of marine Diesel engine,a finite time thermodynamic model of two-stage thermoelectric generator with air-cooling device driven by waste gas heat of marine Diesel engine is established.Thermal resistance distribution and temperature variations along the flow passage are obtained.In the case of the temperatures of heat reservoirs change over flow passage,the effects of heat source parameters and module parameters on the power output per-area and efficiency are derived.The results show that waste gas temperature drops 30℃ per meter and the maximum power-per-area of are available for waste gas heat of marine diesel engine of 350℃.
