Description
- This invention relates to a fan and a ventilation unit comprising a fan and a corresponding shroud.
- The ventilation groups referred to in this specification are those generally formed by a fan and a support shroud of the fan, for cooling radiators in automotive applications.
- The fan is usually constituted by an electric motor, preferably of the closed type, for actuating a corresponding fan, of the axial type in the present case.
- The electric motor has a casing, a cap for closing the casing and an outlet shaft which is solidly constrained to the fan by means of a cup-shaped hub which at least partly houses the motor itself and from which a plurality of blades project.
- The shroud is provided for supporting the motor by means of a corresponding support ring and for at least partly housing the fan in such a way as to optimise heat removal from the radiator.
- The shrouds, in particular, generally comprise an external tubular member, having a substantially cylindrical end wall, to which the support ring is connected by means of a plurality of arms or spokes which project from the cylindrical wall internally of the tubular element.
- The support ring is coaxial with the cylindrical wall and the motor is mounted coaxially with the support ring.
- The prior art solutions have some drawbacks.
- The positioning and fixing of the fan in the shroud do not enable effective removal and evacuation of the heat generated by the electric motor in operation, i.e. an adequate cooling of the cap and the casing is not enabled.
- In general, the ring of the shroud for supporting the motor surrounds the motor itself and does not allow the circulation of an air flow suitable carrying of the heat generated in use.
- The hub of the fan is in general very closed on the motor and also prevents a circulation of air which cools down the casing and the cap of the electric motor by convection.
- Failure to cool the motor limits the operating temperature and therefore the performance.
- If, on the other hand, particular levels of performance are required, the duration over time of the motor is limited, should it not be properly cooled.
- In this context, the main aim of this invention is to obviate the above-mentioned drawbacks.
- The aim of the present invention is to provide a fan which contributes to generating a flow of air for cooling the electric motor, in particular both the cap and the casing.
- Another aim of the invention is to disclose a ventilation group which allows a better passage of air around the cap and the casing of the electric motor than the prior art solutions.
- The stated technical purpose and aims of the invention are substantially achieved by a fan according to claim 1 and a ventilation group according to
claim 10. - Further characteristics and advantages of the invention will become more apparent from the non-limiting description that follows of a preferred but non-limiting embodiment of a ventilation group as illustrated in the accompanying drawings, in which:
