Abstract: A vehicle includes a thermal management system. The thermal management system of the vehicle comprises an engine cooling system, an air conditioning system, and a low-temperature cooling system. The engine cooling system comprises an engine, an intercooler, a first heat dissipation device, and a first fan. An air outlet end of the intercooler is in communication with an air inlet manifold, and an air inlet end of the intercooler is in communication with a supercharger. The first fan is used for dissipating heat for the intercooler and the first heat dissipation device. The low-temperature cooling system comprises a second heat dissipation device and a second fan, and the second fan is used for dissipating heat for the second heat dissipation device and a condenser.

Abstract: An engine includes an engine water jacket, a water pump and a thermostat assembly. The engine water jacket, the thermostat assembly and the water pump are connected to form a circulation passage. The thermostat assembly is connected between the engine water jacket and the water pump. The engine water jacket includes a cylinder head water jacket and a cylinder block water jacket. The thermostat assembly is configured to enable the coolant to enter the cylinder head water jacket of the cylinder head water jacket and the cylinder block water jacket upon cold start.
