Embodiment Construction

[0019] figure 1 For a schematic structural diagram of a vehicle thermal management system provided by an embodiment of the present invention, see figure 1 , the vehicle thermal management system includes: a refrigerant circulation system 1, a battery circulation system 2 and a motor circulation system 3;

[0020] Refrigerant circulation system 1 and battery circulation system 2 exchange heat through the battery heat exchanger. A section of pipeline at the return air end of the refrigerant circulation system and a section of pipeline of the battery circulation system are coaxial, that is, the refrigerant pipeline passes through the battery circulation pipeline , to ensure that the return air temperature of the refrigerant is similar to the temperature of the battery circulating fluid; the battery circulation system 2 and the motor circulation system 3 are connected according to heating needs;

[0021] When the battery circulation system 2 and the cab are in a cooling state, th...

Abstract

The invention provides a thermal management system for a vehicle, which improves the heating efficiency under normal working conditions by exchanging heat with the outside air, absorbing waste heat of a motor and keeping warm. Even at extremely low temperatures, such as -40°C, compared with existing technologies, it still has higher heating efficiency, thereby improving the energy utilization efficiency of new energy vehicles.

Description

technical field [0001] The invention relates to new energy vehicle technology, in particular to a vehicle thermal management system. Background technique [0002] Hybrid and pure electric vehicles will be the development trend of the future automotive industry. Compared with traditional fuel vehicles, the powertrain structure of new energy vehicles (pure electric and hybrid) has undergone tremendous changes. After using the electric motor to replace the fuel engine in the traditional car, its thermal management system has also undergone fundamental changes. The thermal management system of the new energy vehicle mainly includes the thermal management of the battery, the thermal management of the control unit and the thermal management of the cockpit. [0003] Among the existing patents and technologies, the more common thermal management systems of electric vehicles use PTC, HIC and other resistance heating, and the heating efficiency is low.
