Erbslöh Aluminum is an aluminium extrusion company, with a strong focus on light weight profiles with tight tolerances fulfilling high surface demands. One of several major columns of the product portfolio are multiport microtubings for heat exchangers, i.e. condenser and evaporator applications.
Since battery electric vehicles become an alternative to internal combustion engines, wide and flat tubes for battery cooling have been developed. Add-ons like electrically isolating coatings are under development as well as integrated concepts of Li-ion cells joined with cooling tubes. Any kind of medium can be used, classical refrigerants like R1234yf, water-glycol as well as CO2.
Erbslöh is holding several patents on battery cooling and is continuously applying for new patents. Erbslöh is european market leader for battery cooling tubes – a small but quickly evolving market.
