摘要:

随着国民经济的不断发展,汽车保有量逐年攀升,与此同时,环境、能源以及噪声等问题不断恶化,节能减排已成为我国汽车工业发展的市场和技术大势所趋。本文开发了一套平板式的汽车尾气温差发电装置,可回收汽车尾气的能量发电,以供汽车使用,从而可达到节约燃油的目的。装置由两个吸热气箱和三个冷却水箱相互层叠而成,吸热气箱和冷却水箱间夹装热电片组。将该装置与一辆实验皮卡车进行了集成,安装于三元催化器和消声器之间。实际道路的测试过程中,该发电模块的峰值功率可达300 W,可在一定程度上满足汽车正常行驶中的电力需求。

Under the great development of Chinese economy, the recent number of cars being sold and on road has increased year after year in China. Meanwhile, there are huge issues concerning the en-vironmental quality, the energy supply, and noise levels. To address the issues, this paper intro-duces a technology utilizing flat-plate model of the automobile tail-pipe energy harvesting (ATEH), which recovers energy from the automobile pipe exhaust gas. This technology can reduce a car’s gasoline consumption. The ATEH is designed, and is composed of two hot boxes and three cold boxes. The exhaust gas flows through the hot boxes, while the cooling water flows through the cold boxes. Thermoelectric units are assembled between one hot box and one cold box. To test its roadside performance, the ATEH was integrated with a pickup truck. The installed unit is located between the three-way catalyst and the muffler. Based on the automobile roadside test, maximum output power of the ETEG was 300 W per unit. To some extent, the ATEH can meet the normal electricity demand of a car.
