ABSTRACT:
A control box is mounted on an external wall of a heat exchanger, such as a motor vehicle engine cooling radiator, adapted for the air cooling of a coolant fluid. The control box contains a temperature sensor for detecting the temperature of the coolant fluid. The control box projects from the outside of the heat exchanger, with the temperature sensor projecting from the main body of the control box into the interior of the heat exchanger. The control box is arranged to switch a motorized fan unit for giving a forced circulation to the cooling air which cools the coolant fluid itself, and is electrically connected directly to an electrical supply source and to the power input terminals of the fan motor.
