摘　　要：分析了目前汽车余热利用技术的现状和余热回收系统的特征,展示了各种余热回收系统的基本结构。分别对余热制冷技术和余热发电技术的系统参数和结构特征进行了对比。根据两种技术存在的共同问题,提出了推动余热利用发展的关键技术。The existing situation of the techniques used in vehicles about recycling the exhaust energy is analyzed. The paper introduces the characteristics of waste heat recovery systems, and shows the basic structure of waste heat recovery system. For waste heat refrigeration technology and waste heat electric-power generation technology, their parameters and characteristics of the systems are compared respectively. According to two kinds of technologies in a common problem, the key technologies of waste heat recovery are put forward.
