Thermal management system and vehicle

Abstract

The invention provides a thermal management system and a vehicle. The heat management system comprises a kettle assembly, a pump assembly and a valve unit, the kettle assembly comprises a shell and a cover plate, the cover plate is covered with the shell, the shell and the cover plate jointly form a containing cavity, and the pump assembly and the valve unit are installed on the shell; the containing cavity is internally provided with a plurality of pipelines for liquid circulation, the shell is provided with a plurality of connectors communicated with the containing cavity, the first ends of the pipelines are communicated with the connectors in a one-to-one correspondence mode, and the second ends of the pipelines and part of the pipelines are located outside the containing cavity; the valve unit is provided with a plurality of valve ports, the valve ports communicate with the connectors in a one-to-one correspondence mode, and the valve unit is used for controlling disconnection or communication of the connectors and the valve ports corresponding to the connectors, so that disconnection or communication between the pipelines is controlled. According to the thermal management system, the total length of the pipeline can be shortened, the flow resistance in the pipeline is reduced, and the working efficiency of the system is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a heat management system and a vehicle. Background technique [0002] With the popularity of new energy vehicles, the importance of vehicle thermal management systems has become increasingly prominent. Compared with traditional fuel vehicles, the thermal management system of new energy vehicles has become more complex and has higher requirements. [0003] At present, pure electric vehicles usually need to install many thermal management components according to the thermal management requirements of the whole vehicle, such as: water pumps, heat exchangers, water-cooled condensers, two-way solenoid valves, two-way proportional valves, cooling pipelines, etc. In order to improve the cruising range of electric vehicles, there are more and more requirements for the design of the thermal management of the vehicle, and the number of components required in the thermal management system...
