Abstract
A stator device for an axial flow fan has a plurality of first stator elements and a corresponding plurality of second stator elements, the first stator elements being disposed axially rearwardly of the second stator elements so as to define an air flow slot therebetween.
Claims24
A stator device for an axial flow fan comprising a plurality of stator members depending from a peripheral wall defining an opening for air flow from the fan, said stator members extending radially inwardly to a fan motor support member, wherein the stator device has an axially rearward extremity and an axially forward extremity, the rearward extremity, in use, being disposed more remote from the fan, and the forward extremity being disposed closer to the fan, the plurality of stator members comprising a plurality of first stator elements and a corresponding plurality of second stator elements, the first stator elements being disposed axially rearwardly of the second stator elements wherein a forward edge region of the first stator elements and a rearward edge of the second stator elements defines a slot therebetween, the slot having a circumferential extent wider than an axial extent the axial extent, disposed substantially parallel to the direction of the air flow.
An axial flow fan device comprising an axial flow fan disposed in a fan shroud in spaced relationship to a vehicle heat exchanger, the fan shroud having an internal peripheral wall defining an opening for air flow from the fan and a fan motor being secured to a fan support portion, the system further comprising a stator device depending from said wall and extending to said support portion, the stator device comprising a plurality of first stator elements and a corresponding plurality of second stator elements, the first stator elements being disposed axially rearwardly of the second stator elements wherein a forward edge of the first stator element and a rearward edge of the second stator elements defines a slot therebetween, the slot having a circumferential extent wider than an axial extent, the axial extent disposed substantially parallel to the direction of the air flow.
A stator device for an axial flow fan, having an axially rearward and an axially forward extremity, the rearward extremity, in use, being disposed more remote from the fan and the forward extremity being disposed closer to the fan, the stator device comprising a plurality of first stator elements, a plurality of second stator elements, and a plurality of third stator elements, wherein the first stator elements are disposed axially rearwardly of the second stator elements and the third stator elements are disposed axially forwardly of the second stator elements wherein a slot is provided between each of the first and second, and the second and third stator elements, each slot having a circumferential extent wider than an axial extent, the axial extent disposed substantially parallel to the direction of the air flow.
An axial flow fan, comprising:
- a first stator element having a first edge and a second stator element having a second edge, the first stator element being disposed axially rearwardly of the second stator element where the fist edge and the second edge defining a slot, the slot having a circumferential extent substantially greater than an axial extent, the axial extent disposed substantially parallel to a direction of air flow through the fan.
