New energy vehicles use power batteries as drivers, because the battery will produce a lot of heat during the operation of the vehicle, therefore, having a good cooling system and reasonable heat dissipation has an important impact on the safety of electric vehicles and the life of the battery. Power battery heat dissipation has many ways, and water-cooled heat dissipation, as a new force and future trend in the field of heat dissipation, is playing an important role in the electric vehicle industry. The battery cooling system of new energy vehicles mainly includes important components such as batteries, battery coolers and water cooling plates, which are important components of the thermal management system of new energy vehicles.
New energy automobile liquid cooling plate with aluminum alloy composite material 3003/4343 water cooled plate by the base plate composite plate and the runner plate after brazing processing, the base plate composite plate and the runner plate formed a coolant flow channel to achieve the function of battery heat dissipation, so for the water-cooled plate with aluminum alloy material need to have coolant corrosion resistance, high stamping formability.3003 aluminum plate is an aluminum-manganese alloy, and the material properties meet the requirements of corrosion resistance, processability, etc., and meet the design and application requirements of water-cooled plate.
Introduction of the advantages of new energy vehicles water cooling heat dissipation:
1, good compatibility. The modular design allows the water-cooled cooling system to solve the heat dissipation problem of different power and different environment, which is more fine and more standard and professional.
2, high heat dissipation coefficient. Water cooling cooling rate is fast, good temperature equalization, fluid (temperature and flow) control is simple. The liquid medium has high heat transfer coefficient, large heat capacity and fast cooling speed, which has remarkable effect on reducing high temperature and improving the consistency of temperature field of battery pack.
3, water-cooled heat dissipation has the characteristics of quiet green, is the main way of current electric vehicle heat dissipation.
