Abstract

The invention discloses a distributed drive intelligent heat management system for a new energy automobile. The system comprises a motor heat dissipation unit, a cabin air conditioning unit and a battery temperature control unit, wherein the motor heat dissipation unit comprises a first radiator and a first liquid pump which are connected with a motor heat dissipation loop, the cabin air conditioning unit comprises a cabin air conditioner, a compressor, a second radiator and a heat exchanger; the battery temperature control unit comprises a battery heat dissipation loop used for supplying cooling liquid to a power battery and a battery heating loop, wherein the power battery is heated by a battery heating loop at a low temperature environment to make the power battery be started and run ata control temperature; the heat exchanger is further connected in the motor heat dissipation loop and / or the battery heat dissipation circuit / the battery heating loop. According to the management system, the heat energy distribution can be optimized, the heat energy loss can be reduced, the electricity can be saved, and the battery life is rather prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a thermal management system. Background technique [0002] With the development of electric vehicles, a new type of electric vehicles with distributed drive has emerged. For electric vehicles, the motor is prone to heat and needs to be cooled in time. In addition, the temperature control requirements of the battery are very strict. In order for the car to run normally, we need to reasonably design the motor heat dissipation unit and the battery temperature control unit so that the motor and The battery is in normal working condition. [0003] The existing motor heat dissipation system and battery temperature management system are mainly aimed at electric vehicles with central transmission, and are not suitable for distributed drive. There is a lack of a complete and reasonable vehicle thermal management system suitable for distributed drive vehicles. Contents of th...
