Miba Battery liquid cooling system FLEXcooler

    Thermal management is a key technology in the electric vehicle and chemical energy storage markets. Extending battery life, shortening charging time, obtaining higher energy density, and preventing thermal runaway are all directly related to efficient battery cooling systems.
Liquid cooling, with its high specific heat capacity and large heat transfer coefficient, is becoming the mainstream technology to replace traditional air cooling. The most widely used cold plate indirect cooling in liquid cooling technology is facing some application challenges while developing rapidly.

    Traditionally, the liquid cooling of battery cells uses serpentine or planar cold plates, which are usually rigid components made of aluminum extrusion or stamping. The coolant flows in the channel of the aluminum cooling plate, taking away the heat from the battery. Due to the rigid contact between the battery unit and the cooling plate, inevitable manufacturing and assembly tolerances always result in air gaps between the two, leading to poor thermal conductivity. Therefore, it is necessary to add thermal conductive paste to achieve good thermal coupling between the battery unit and the cold plate.

    FLEXcooler developed by Miba Battery Systems ® The flexible liquid cooling system brings a new design that overturns the rigid cooling plate and is suitable for battery cooling of all types, sizes, and shapes.

    For cylindrical batteries, the FLEXcooler flexible cooler can achieve direct thermal contact with the battery unit without the need for thermal paste. When the coolant flows through the flexible cooler inserted between the batteries, the pressure exerted by the coolant causes the FLEXcooler to expand, allowing them to fill the gap between the battery cells and tightly adhere to the battery surface. Therefore, it is possible to achieve double-sided cooling of cylindrical batteries in a simple design.

   The thermal management of batteries is crucial for the optimal performance of electric vehicles. To achieve good thermal coupling between battery modules/cells and the cooling system, Miba offers options including FLEXcooler ® Various battery cooling technologies including. The FLEXcooler, which is flexible, flexible, and lightweight, takes into account the three major advantages of flexible appearance, flexible size, and flexible flow field.
