    The present invention relates to a cooler arrangement of a hybrid vehicle (1) powered by a supercharged combustion engine (5) and an electric power unit (6). The cooler arrangement is arranged at a front portion of the v ehicle. The cooler arrangement comprises a radiator (10) of a first cooling system which cools the combustion engine (5), a radiator fan (18) creating an air flow through the radiator (10), a charged air cooler (11) arranged in a position upstream of the radiator (10) with respect to the intended air flow direction through the radiator (10) and a cooler unit (12, 13, 21) of a second cooling system which cools an electric energy storage (8) and the power electronics (9) of the electric power unit (6), The cooler unit (12. 13, 21) comprises a cool er (12) arranged in a position upstream of the radiator (10) with respect to the intended air flow direction through the radiator (10) and at least one fan (13) configured to create an air flow through the cooler (12).(Fig. 2)
