Description

technical field [0001] The invention relates to the technical field of automobile auxiliary equipment, in particular to a method and device for storing and converting automobile exhaust heat energy. Background technique [0002] At present, the efficiency of internal combustion engines used in automobiles is very low, only about 20% of the energy is converted into power, and the remaining 80% of the energy is discharged into the atmosphere through exhaust gas in the form of heat. The temperature of the exhaust gas of a car engine is above 500 degrees Celsius, and the temperature of a high-power engine is even higher. Collecting and storing the heat energy of automobile exhaust, converting it properly, and using it for food processing, heating, and power generation can not only increase the functions of automobiles, but also improve energy utilization and reduce fuel consumption and greenhouse gas emissions. [0003] As we all know, during the long-distance driving of the ca...
