The invention can efficiently dissipate heat of the battery and realize effective protection of the battery at the same time.

Description

technical field [0001] The invention belongs to the technical field of automobile supporting devices, in particular to a new energy automobile power battery cooling system. Background technique [0002] At present, electric vehicles have the advantages of low pollution, low noise, and use of new energy, and have become an important part of the urban transportation system. Judging from the current situation of use, electric vehicles have broad prospects. However, there are still some deficiencies in current electric vehicles: for example, the main power source of electric vehicles, the power battery, must be at a suitable temperature to exert its best performance, and its suitable temperature is usually 10-35 ° C. If there is no corresponding The temperature of the power battery will soon exceed 35°C when the car is running. Once the power battery is overheated, it will not only affect the performance of the battery itself, shorten its service life, but also affect the safet...

However, there are still some deficiencies in current electric vehicles: for example, the main power source of electric vehicles, the power battery, must be at a suitable temperature to exert its best performance, and its suitable temperature is usually 10-35 ° C. If there is no corresponding The temperature of the power battery will soon exceed 35°C when the car is running. Once the power battery is overheated, it will not only affect the performance of the battery itself, shorten its service life, but also affect the safety of electric vehicles.

[0003] At present, the air cooling method adopted by the electric vehicle power battery has insufficient sealing and poor battery protection ability, and it is easy for debris to enter the battery box
