Patent No. EP4022711 (titled "Arrangement Consisting Of A Battery And A Cooling System, Comprising A Filler Element For Heat Transfer From The Battery To The Cooling System") was filed by GKD Gebr Kufferath on Feb 3, 2021. The application was issued on Jul 31, 2024.
A battery cooling system with improved thermal interface, comprising a battery, a cooling system, and a filling element with a three-dimensionally deformed layer for enhanced heat transfer between the battery and cooling system. The deformed layer provides increased contact surface area and thermal conductivity, while a thermal paste or adhesive can be applied to further enhance heat transfer between the filling element and adjacent components.
