  • a fourth radiator is primarily used to cool coolant for cooling of the combustion engine. All radiators are arranged in a common air flow passage in the vehicle. Since the first radiator and the second radiator are arranged in positions upstream of the third radiator and the fourth radiator it is possible to cool the energy storage and the power electronics with coolant of a lower temperature than the coolant cooling the condenser and the combustion engine.

It is, for example, possible to use other kinds of valves and connecting lines for creating primary coolant flow paths and alternative coolant flow paths between the respective radiators and the components to be cooled.
  • the coolant circuits ci_ 4 may be used to cool more objects than the above indicated.
  • the second circuit c 2 may, for example, also be used to cool the electric machine 2a.
