Definitions
- the invention relates to a radial fan according to the preamble of claim 1; such a radial fan is generally known
- a distribution housing adjoining a radial fan with a surrounding spiral housing, through which the air is to be brought into a specific blow-out direction, as low as possible with simple means.
- the measure according to the invention allows the air particles emerging from the spiral housing surrounding the impeller of the radial fan to flow through the air distribution housing in a targeted direction with little loss, largely avoiding eddies and dead areas.
- the air distribution housing is essentially composed of straight or possibly circular wall parts in order to achieve the simplest possible manufacturing and assembly engineering construction
- air baffle plates in the form of logarithmic spirals are arranged in the air distribution housing, which ensure low-loss flow of the air allow air particles emerging from the volute surrounding the impeller of the radial fan;
- the air baffles in the form of logarithmic spirals can be dispensed with in whole or in part if the shape of the air distribution housing itself essentially corresponds to that of a logarithmic spiral, which enables a low-loss flow and thus deflected by a few flow-restricting resistors.
- an air distribution housing 3 adjoins the outlet side of a spiral housing 2, which surrounds an impeller 1 of a radial fan, which is only indicated schematically.
- the construction of the housing wall parts forming the air distribution housing 3 is characterized by the simplest possible manufacturing and assembly technology, in which the wall parts are assembled from only flat or at most circular sheet metal parts.
- the air distribution housing 3 which is designed to be as simple as possible in terms of production and assembly technology, three air baffles 31, 32, 33 are arranged in logarithmic form in such a way that the flow particles emerging from the outlet side of the spiral housing 2 surrounding the impeller 1 pass through the air baffles 31, 32, 33 formed guiding device can flow in a targeted manner with as little loss as possible to the outlet side of the air distribution housing 3.
- FIG. 2 shows a radial fan in which the air distribution housing 4, which adjoins the outlet side of the spiral-shaped housing 2 surrounding the impeller, is itself in the form of a logarithmic spiral; This is achieved in that the walls 41, 42 run similarly according to a logarithmic spiral as the air guide plates 31, 32, 33 in FIG. 1.
- An air nozzle 43 with an outlet liner 44 is arranged on the outlet side of the air guide housing 4.
