New energy battery liquid cold plate applications

  Thermal cooling  is very important for new energy vehicles, because its heating power is very large, which requires high-quality high-power heatsinks, while the traditional air-cooled heatsink generally can not meet their heat dissipation needs, especially the heat dissipation of new energy vehicle power battery pack, which has the characteristics of sealing. 

      The design  requires that the electric vehicle can operate efficiently and stably under various weather conditions throughout the year, and the vehicle battery pack directly affects the acceleration and endurance distance of the vehicle, so its stability is a key technology of the whole vehicle, and the key technology to ensure the stable development of the battery pack lies in its heat dissipation.The battery heat dissipation of electric vehicles generally adopts the liquid cooling  system. The excellent liquid cold plate and related pipeline connection technology ensure that it operates at an appropriate temperature. 

   An excellent thermal management system of power battery pack needs to ensure that the temperature of each single battery is constant throughout the year. Even if the battery is used in hot weather, it can ensure timely heat dissipation and prevent the weakening of battery life or expansion and explosion. In addition, the battery is used  in extremely cold weather to ensure that the interior of the battery is warm enough, Performance and life will not be affected. The heat dissipation of the battery is that the liquid coolant flows through the water-cooling plate at the bottom of the battery pack, and then the cooling plate with excellent thermal conductivity is in direct contact with the single battery, so as to quickly cool the battery.

   The cooling system and heating system constitute the overall thermal management system of electric vehicles. Charging in extreme environments is a technical difficulty in the development of new energy vehicles. At the initial stage of charging, whether the heating system can automatically start heating to ensure the temperature of the battery is very critical, which has high requirements for the sealing of the power battery pack shell, Good sealing performance to ensure temperature storage.
