The invention discloses a thermal management system of a vehicle and the vehicle. The thermal management system consists of a cooling circuit, a constant temperature circuit, a heating circuit and an expansion pot. The cooling circuit, constant temperature circuit and heating circuit are connected to the expansion pot. The expansion pot is used for liquid filling and exhausting of the cooling circuit, constant temperature circuit and heating circuit . In the thermal management system of the vehicle in the above embodiment, an expansion kettle is used to connect the cooling circuit, the constant temperature circuit and the heating circuit, which can reduce the cost of the vehicle and improve the efficiency and production efficiency of filling the expansion kettle with coolant on the vehicle production line. Speed, and improve the efficiency of vehicle after-sales maintenance.
Description
technical field [0001] The present invention relates to the technical field of thermal management, and more specifically, to a thermal management system of a vehicle and the vehicle. Background technique [0002] At present, the electric vehicle thermal management system includes three circuits, namely the warm air heating circuit, the electric drive cooling circuit and the battery constant temperature circuit. These three circuits generally adopt a liquid circuit system and are independent of each other. Existing vehicles require three expansion pots as each circuit requires one expansion pot for coolant filling and venting. At the same time, three filling devices need to be installed on the vehicle production line to fill the three expansion pots with coolant at the same time, which makes the production cost of the vehicle higher, and the filling efficiency is low, and the waterway structure on the vehicle is complicated and the waterway layout is difficult. And limited,...
