Abstract
(EN) A waste heat energy conversion system. The system comprises: a thermoelectric conversion apparatus having a hot end and a cold end, the hot end and the cold end being used for obtaining a temperature difference, and the thermoelectric conversion apparatus realizing thermoelectric conversion according to the temperature difference; a fluid pipeline, which allows a working fluid that absorbs and releases heat energy to flow through, the fluid pipeline comprising a first fluid pipeline, and the first fluid pipeline allowing working fluid that has heat source heat energy to flow to the hot end of the thermoelectric conversion apparatus; a fluid pressurization apparatus, which pressurizes the working fluid in the first fluid pipeline so that the temperature rises; and a first heat exchanger, which is connected to the hot end of the thermoelectric conversion apparatus and performs heat exchange with the working fluid, the temperature of which has risen after same has been pressurized by the fluid pressurization apparatus, so that the temperature of the hot end rises. The waste heat energy conversion system can increase the temperature difference between two ends of a thermoelectric conversion apparatus, such that the waste heat conversion utilization efficiency is effectively improved.
(FR) Système de conversion d'énergie thermique perdue.
