Thanks to liquid cooling, the PotisBank-L3.7 provides rapid heat exchange and efficient cooling of the system. Meanwhile, due to the high specific heat capacity of the liquid, its own temperature does not change significantly after absorbing a large amount of heat, allowing it to maintain a very small temperature differential. Compared to air cooling, the specific heat capacity of the liquid is less sensitive to altitude and atmospheric pressure, enabling it to maintain high cooling efficiency. The system's energy consumption is reduced by 20%, and the battery lifespan is increased by 10%, effectively lowering the energy consumption ratio.
