Abstract

The invention discloses an efficient thermal management system for a new energy vehicle. The efficient thermal management system comprises an integrated heat exchange component, an electromagnetic thermal expansion valve, a battery pack, a compressor, a condenser and a battery low-temperature radiator which are arranged outside an HVAC assembly, wherein the integrated heat exchange component and the electromagnetic thermal expansion valve are closely attached to each other for heat exchange. The efficient thermal management system for the new energy vehicle is ingenious in design and easy to implement. When the ambient temperature is lower than the water temperature of the battery low-temperature radiator, a traditional cooling method of air cooling and water cooling is adopted to achievestability, reliability and extremely low energy consumption with almost no influence on the range of the new energy vehicle. When the ambient temperature is higher than the water temperature of the battery low-temperature radiator, a traditional air-conditioning refrigeration method is adopted to achieve extremely high heat exchange efficiency, eliminate the influence of the ambient temperature and enable a heat exchange process to be stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of automobile heat management, and in particular relates to a high-efficiency heat management system for a new energy automobile. Background technique [0002] New energy vehicles refer to vehicles powered by vehicle-mounted power supplies and driven by motors to drive wheels, which meet the requirements of road traffic and safety regulations. Since the impact on the environment is smaller than that of traditional vehicles, and with the increasingly stringent requirements for energy conservation and emission reduction, the development prospects of new energy vehicles are widely optimistic. [0003] The battery pack of new energy vehicles will generate a lot of heat during operation, and it is necessary to cool the high-temperature battery pack to ensure the normal operation of the battery pack. At present, there are two main cooling methods for new energy vehicle battery packs: one is to cool the battery pa...
