Abstract

The invention provides a vehicle heat exchange system. The battery heat exchanger in the system exchanges heat with the battery pack through the phase change of the refrigerant to realize heating, cooling, temperature balance and the like for the battery pack. The low-pressure gaseous refrigerant is compressed into high-pressure gaseous refrigerant by the compressor, and then transported to the position where heat exchange is required. Moreover, when heat insulation from the external environment is required, only a thin gaseous refrigerant exists in the battery heat exchanger. At this time, the battery heat exchanger realizes thermal barrier capability, blocks heat conduction between battery cells, and prevents The phenomenon of thermal runaway spreads between battery cells. When the temperature of the battery pack is close to or reaches the critical temperature of thermal runaway, the high-pressure and low-temperature liquid refrigerant in the refrigerant storage tank is sprayed from the refrigerant spray device to cool down the battery heat exchanger and battery cells to realize the protection of the battery pack. thermal safety management.

Description

technical field [0001] The invention belongs to the technical field of heat exchange of new energy vehicles, in particular to a vehicle heat exchange system. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle control and drive. Among them, new energy vehicles include pure electric vehicles, hybrid vehicles and so on. [0003] For new energy vehicles that use batteries (or battery packs) as energy storage power, the heat exchange effect of the battery pack directly determines its performance, life and safety. When the temperature of the battery pack is too low, its internal resistance is large, and charging at low temperature will affect the safety of the battery. When the temperature of the battery pack is too high, harmful reactions such as electrode and electrolyte decomposition may occur, causing permanent damage to the internal structure of the batter...
