A helicopter with an improved cooling system, wherein the helicopter comprises a main rotor (3) coupled to an internal combustion engine (4) by means of transmission means (5) and wherein the cooling system (1) comprises a coolant circuit (15) of the engine (4) and a lubricating oil circuit. The cooling system (1) comprises first liquid cooling means (15), second oil cooling means (16), a radiator (22) and a fan (17) housed in an air conveyor (20) arranged in an inner compartment of the helicopter. The fan (17) is located at the inlet of the air conveyor (20) and is not visible from the outside. The cooling system (1) comprises a single radiator (22) located downstream of the fan (17). The first cooling means (15) comprise the single radiator (22), the second oil cooling means (16) comprise a heat exchanger (40) separate from the single radiator (22) and located below the same, the heat exchanger (40) being configured to use as an exchange fluid the coolant exiting the single radiator (22) and having a coolant liquid outlet fluidically connected to the engine (4).
