ABSTRACT:
In an assembly of a heat exchanger, such as a motor vehicle engine cooling radiator, with a motorised fan unit for directing a forced flow of air through the heat exchanger, the motor of the fan unit has a base plate which bears on one of the major faces of the matrix of the heat exchanger, which consists of tubes and fins fitted over the tubes. The base plate has lugs extending radially outwardly and formed with holes. In order to fasten the motorized fan unit to the heat exchanger, the matrix of the latter is clamped between the motor base plate and a securing plate which is applied on the opposite major face of the matrix, by means of screws through the respective holes in the lugs. Each screw is surrounded by a spacing sleeve fixed to the securing plate and abutting endwise on the corresponding lug of the motor base plate. The spacers and associated screws extend through apertures formed by cutting portions out of appropriate fins, to form voids through the whole thickness of the matrix.
