The liquid-liquid heat exchanger is connected with the warm air core body and the high-temperature radiator through pipelines, and the warm air core body and the high-temperature radiator are connected with the liquid-liquid heat exchanger in parallel. According to the invention, efficient matching of the electric pile and the whole vehicle thermal management system can be realized from the angles of waste heat recovery of multiple components and multi-medium heat conversion.
