Definitions
- the invention relates to a housing ring of an axial fan, which is often referred to in technology as a wall ring.
- Housing rings of this type enclose the impeller of the axial fan and are used in particular for mounting the axial fans.
- the invention is based on the object of making the housing ring easy to assemble and developing it for further possible uses in which further components can be mounted on the housing ring radially on the outside.
- a housing ring of an axial fan formed from at least two ring segments, with a radially outwardly facing jacket surface is proposed, on whose jacket surface at least one fastening rail is integrally formed, which forms a fastening channel for inserting and fixing fastening elements.
- the fastening elements for fixing the ring segments to one another can be introduced in order to connect the ring segments to one another and thus to form the housing ring.
- the mounting rail can also be used to attach external components, e.g. cables, electrical components, covers or other housing parts.
- the fastening of the ring segments at the joints can be achieved mechanically, for example by means of slot nuts, rivets or screws or also by welding.
- the housing ring is characterized in that the fastening channel is designed to be radially outwardly open and has a flinter grip. External components can therefore be pushed into the fastening channel from the radial outside and fixed using the flinter grip.
- the at least one fastening rail runs around the housing ring in the assembled state in the circumferential direction, preferably completely and continuously.
- the housing ring is preferably composed of several ring segments, so that the space requirement is reduced in the non-assembled state.
- the sub-segments of the housing ring can be placed one inside the other to save space before assembly.
- An embodiment of the housing ring that is advantageous with regard to the production provides that it is made from an extrusion that can be bent into a circular or ring shape. on is manufactured.
- the housing ring is characterized in that the at least one fastening rail is formed by two legs which, starting from the jacket surface, first extend radially and then axially towards one another in order to create the fastening channel. The legs do not meet, so that the fastening rail remains open radially.
- the rear grip is determined in this embodiment by the axial sections of the legs.
- the housing ring it should be ensured with the housing ring that it can be used variably and that it meets different customer specifications.
- One of the fastening rails can be used, for example, to connect the ring segments, and the other fastening rail (s) to connect components.
- an embodiment of the housing ring provides that in each case at least one fastening rail in a first axial half of the housing ring and at least one fastening rail in a second axial half of the
- housing rings are formed.
- the fastening rails also each have a fastening channel with a different one
- the housing ring is also characterized in that the housing ring forms a tab extending in the radial direction with a cavity on at least one of its axial end edges, the at least one tab forming an axial bearing surface. It is preferred that geometrically identical tabs are formed on both axial front edges of the housing ring.
- the invention also comprises an axial fan with a motor, an impeller and a housing ring enclosing the impeller as described above.
- FIG. 1 shows a perspective view of a housing ring
- FIG. 2 shows a side view of the housing ring from FIG. 1
- FIG. 3 is a sectional view of the housing ring from FIG. 1.
- FIGS. 1-3 show an exemplary embodiment of the housing ring 1 of an axial fan, which is formed from two ring segments that are joined together at the interface 6.
- the housing ring 1 comprises an annular body with a radially outwardly facing jacket surface 2 and an inner jacket surface 8 that points radially inwards towards the impeller of the axial fan (not shown)
- fastening rails 3 completely encircling the housing ring 1 in the circumferential direction, each of which has a radially open fastening channel 9 for introducing and fixing fastening Forming elements (not shown).
- the mounting rails 3 are axi al spaced and on two different axial halves of the
- Each of the fastening rails 3 is formed by two axially spaced legs 11, which extend with their section 11 'starting from the lateral surface 2 first radially outward and then with their section 11 ′′ axially towards one another, but without meeting one another.
- the fastening channels 9 remain open radially outward.
- the fastening rails 3 each have a fastening channel 9 with a different geometric cross-sectional shape, since the sections 11 'of the lower fastening rail 3 in FIG. 3 are longer than those of the upper fastening rail 3 shown that the housing ring 1 forms the tabs 14 extending in the radial direction, each with a cavity 12, on both of its axial end edges 5, 7.
- the tabs 14 provide axial contact surfaces or contact surfaces, for example, for mounting the housing ring 1 on a wall.
- the tabs 14 are geometrically identically shaped and with their cavities 12 each form a receiving space, e.g. for screws.
