A cooling system for cooling the electrical or electronic equipment on board an aircraft is equipped with a main closed circuit. A pump circulates a heat transfer medium through the main closed circuit. A main heat exchanger is thermally coupled with the heat transfer medium. A secondary heat exchanger allows direct thermal coupling of the heat transfer medium to air on the outside of the aircraft. A bypass valve located upstream from the secondary heat exchanger allows to block, at least partially, the circulation of the heat transfer medium towards the secondary heat exchanger. A bypass duct connects the bypass valve to a point on the main closed cooling circuit downstream from the secondary heat exchanger to bypass, at least partially, the heat transfer medium towards the main heat exchanger as a function of a setting of the bypass valve.
