An object of the invention is to provide a heat exchanger (radiator) or a cooling module having the radiator and a condenser, which has a higher rigidity against vibration in the vertical direction. To the end, the radiator or the cooling module is mounted to a vehicle by mounting brackets, which are fixed to the radiator tanks at their vertical ends. The mounting brackets have mounting pins, with which the radiator or the cooling module is mounted to the vehicle.
