Fig. 2 is a schematic structural diagram of a thermal management system according to an embodiment of the present invention. The embodiment of the utility model provides a thermal management system can be applied to in the hybrid vehicle to provide thermal management for the hybrid vehicle. As shown in fig. 2, an embodiment of the present invention provides a thermal management system 10, including: the device comprises a water storage kettle 11, a first gas-liquid separator 12, a first electric-driven water pump 13, a three-way ball valve 14, a water-cooled intercooler 15 and a high-low pressure converter 16.
