IMMERSION COOLING
Ensures safety and durability of the battery system
Immersion cooling
There are different types of cooling concepts used for battery systems. One possible, technically sophisticated concept is immersion cooling. In contrast to indirect contact cooling, the battery cells are cooled directly by a liquid. A dielectric fluid is usually guided along the surface of the battery cell in order to absorb and remove as much heat as possible. An immersion-cooled battery is equipped at the system level with a secondary cooling circuit, which in turn cools the cooling liquid. Immersion cooling ensures a longer battery service life and increases safety. The aim is to delay or prevent undesirable events such as thermal runaway and thermal propagation. The requirements apply both to the design of the seal and to the hydraulic conditions in the system.
