目前国内外许多学者对汽车温差发电技术进行了研究,主要利用汽车尾气余热体现在以下方面:(1)改善温差电材料特性,如增大无量纲优值系数、改善热电材料结构等;(2)增大温差,如增强冷端散热;(3)改善汽车尾气结构。但汽车上的其他余热资源并没有有效利用。汽车中冷器在冷却增压器的高温气体时会释放大量的热,若利用这些余热进行温差发电,不仅变废为宝,同时也降低了中冷器气体温度,使发动机的进气量更充分,燃烧更彻底,达到汽车节能高效的目的。汽车中冷器是在增压器出口和发动机入口之间的空气冷却器,使增
At present, many scholars at home and abroad have made research on the thermoelectric power generation technology of the automobile. The main use of the automobile exhaust heat is as follows: (1) to improve the characteristics of the thermoelectric material such as increasing the dimensionless merit coefficient and improving the structure of the thermoelectric material; (2) ) Increase the temperature difference, such as enhancing cold-end cooling; (3) improve the vehicle exhaust structure. But other waste heat resources on the car are not used effectively. The intercooler in the car will release a large amount of heat when it cools the high-temperature gas of the supercharger. If the temperature difference power is used to generate power, the temperature of the intercooler will not only become waste, but also reduce the temperature of the intercooler and make the intake of the engine more Full, more thorough combustion, energy-saving car to achieve the purpose. The intercooler is the air cooler between the supercharger outlet and the engine inlet, making the increase
