As an efficient heat dissipation technology, direct cooling battery pack liquid cooling plate is gradually emerging and becoming an important part of the thermal management system of new energy vehicles.
The basic principle of direct cooling battery pack liquid cooling plate is to use the principle of latent heat of refrigerant evaporation, install the evaporator of the air conditioning system in the battery system, and the refrigerant evaporates in the evaporator and quickly and efficiently takes away the heat of the battery system, thereby completing the cooling of the battery system. Compared with traditional air cooling and liquid cooling technologies, this cooling method has higher heat dissipation efficiency and more uniform temperature control.
In new energy vehicles, the application of direct cooling battery pack liquid cooling plate brings many advantages. First, during the fast charging process, the battery will generate a lot of heat. If the heat is not dissipated in time, it will cause the battery to overheat and affect the performance and life of the battery. Direct cooling battery pack liquid cooling plate can quickly take away the heat generated by the battery and discharge the heat through the cooling system to keep the battery temperature within a safe and ideal range. This not only improves the efficiency and safety of fast charging, but also helps to slow down the aging of the battery and extend the battery life.
Secondly, the application of direct cooling battery pack liquid cooling plate also improves the driving performance and range of new energy vehicles. Through effective temperature control, direct cooling battery pack liquid cooling plate makes the driving performance of electric vehicles more stable. In situations such as high-speed driving or climbing, electric vehicles can provide a smoother driving experience. At the same time, good temperature control can also improve battery efficiency and indirectly improve the endurance of electric vehicles.
In addition, direct cooling battery pack liquid cooling plate is also highly integrated, which can save space inside the battery pack and improve space utilization. This is of great significance for the lightweight design and energy density of new energy vehicles. At the same time, direct cooling technology also reduces the complexity and weight of the cooling system, further reduces the energy consumption and noise of the whole vehicle, and improves the performance and comfort of the whole vehicle.
In summary, the application of direct cooling battery pack liquid cooling plate in new energy vehicles has significant advantages, which can improve the thermal management efficiency of the battery, extend the battery life, and improve driving performance and cruising range.
