Liquid Immersion Cooling for Passenger Aircraft | eVTOL

Aerospace Battery Cooling

Around 2.4% of global CO2 emissions come from the aviation industry and it is responsible for around 5% of global warming. This may not seem like a very big contribution, however, mile for mile, when it comes to the climate, flying is the most damaging way to travel. For example, a return flight from London to San Francisco emits around 5.5 tonnes of CO2 equivalent per person, this is more than twice the emissions produced by a family car in just one year.

When it comes to electrifying the aviation industry there are two main examples of progress – passenger aircraft (short haul) and electric vertical take-off and landing (eVTOL) aircraft. The latter is being developed to operate as an ‘air taxi’, carrying passengers on short journeys.

Of course, the aviation industry faces many challenges when it comes to electrification:

  • Battery technology

  • Range

  • Thermal management

  • Safety

Liquid immersion cooling can help the aviation industry to address these challenges. Batteries require a certain temperature to operate effectively, as do motors. Submerging these components in MIVOLT immersion cooling liquids ensures all areas are completely cooled to a set optimum temperature. This improves performance and safety – there is less risk of thermal propagation. Battery packs can also be denser, which means that less battery cells are necessary. This reduces the weight of the aircraft and lowers costs.
