Definitions
- This invention relates to a system for conveying the air flow generated by a fan and directed against a cooling radiator, such as the cooling radiator of an internal combustion engine.
- the fan is positioned generally downstream of or behind the radiator with reference to the vehicle running direction, in order to enhance the air flow spontaneously generated by the vehicle movement.
- fans which draw air through the radiator are of poor efficiency, this being remedied by encasing them and at least partly tube-enveloping them by providing a cylindrical tube portion fixed to the ends of the fan blades.
- the fan draws peripheral external air through the space defined between the edge of the channel and the edge of the tube rigid with the fan blades, this air obviously not having passed through the radiator so that not only is the noise reduced, but also the fan efficiency.
- An air conveying system is shown in EP-A-0543694, comprising a radiator, a casing connecting the edge of this latter to a circular hole and a tube-enveloped fan partly inserted into said hole, its direction of rotation being such that it generates an air flow directed towards the radiator, and the edge of the fan-surrounding tube which is distant from the radiator extending into a portion not containing blades.
- the object of the present invention is to provide a conveying system for the fan-generated cooling air of a radiator, which has high efficiency and noiseless operation.
- a tube-enveloped and encased fan directing its air flow towards the radiator, its blades being rigid with an outer tube having that edge on the suction side of the fan contained in a stationary circular channel of U cross-section facing the fan.
- Figure 1 is a partial vertical section through the invention.
- Figure 2 shows an enlarged detail of Figure 1.
- the figures show a normal radiator 1 of the type used in internal combustion engines, its peripheral edge being provided with a casing 2 which converges in usual manner, not shown, into a hole 3.
- a fan 4 the blades 5 of which are fixed to a hub 6, is partly inserted into the hole 3.
- the outer edge of the channel 8 is conveniently spaced from the edge of the hole 3 of the casing 2 to create a cylindrical aperture 9.
- the direction of rotation of the blades 5 is such that they convey air towards the radiator 1.
- the air conveyed by the blades is drawn partly from the central space of the channel in accordance with the arrows 10, and partly through the cylindrical aperture 9 in accordance with the arrows 11.
