Definitions

the invention relates to a device for conveying a gaseous medium in a device with high flow resistance.
the device with high flow resistance can be, for example, a ceramic surface burner, which has recently been used in gas boilers.
gas boilers with ceramic surface burners are known (magazine: HLH, heating, ventilation / air conditioning, house technology; magazine of the Association of German Engineers for Technical Building Equipment; June 1989, page 308). They have a relatively high flow resistance, which is on the order of 200 Pascal and more.
the medium to be pumped can either be air or a combustible gas mixture.
the invention is therefore based on the technical problem of creating a device for conveying a gaseous medium in a device with a high flow resistance, in which on the one hand the conveyed medium has a relatively high back pressure and on the other hand has a steep pressure-volume flow characteristic, i.e. in the device, major changes in the pressure generated should only be accompanied by minor changes in the volume flow.
the inherent noise of the device must not exceed the inherent noise of known devices for conveying a gaseous medium.
a radial fan the housing of which has a spiral inner contour and which has a closed fan wheel with backward-curved blades, the diameter of which is very much larger than its flow outlet width.
the pumped gaseous medium has a pressure of 415 Pascals and a volume flow of 6.9 l / s at the intended operating point.
the speed of the fan wheel was about 3800 revolutions per minute.
the housing 1 of the radial fan is closed with the cover 2.
the housing 1 and cover are made of aluminum injection molding.
the cover 2 is screwed to the housing 1 at the edge with the interposition of a seal 3.
the drive motor 4 is flanged, the output shaft 5 of which projects into the housing 1.
the drive motor 4 shown is an electronically commutated DC motor. However, an AC motor can also be used.
the impeller 6 is fastened in a non-positive and / or positive manner.
the flow exit width of the impeller 6 is designated c.
the impeller 6 consists of the lower part 7 with the blades 8 integrally attached to it and the cover 9
the embodiment shown is the length of the blade 8 at the lower end, ie at the lower part 7, longer than at the upper end, ie close to the cover 9.
the impeller 6 can be made of metal or plastic.
the gaseous medium is axially, i.e. through opening 10 in the cover 2, sucked in and blown out radially (into the image plane in FIG. 1).
the blow-out opening is present as a rectangular aperture in the circular flange 11.
the effective shape of the radial fan according to the invention is illustrated in FIG.
the housing 1 has the spiral-shaped inner contour 12.
the dimensions a and b in the exemplary embodiment shown are 156 mm.
the blades 8 are curved backwards, as can be seen from the comparison with the direction of rotation of the impeller 6 illustrated by the arrow 13.
the shape of the blades 8 corresponds essentially to circular arcs. They are arranged in such a way on the lower part 7 that the entry angle ⁇ 1 has almost the same value as the exit angle ⁇ 2. In the exemplary embodiment shown, they have the value of 47 angular degrees.
the tongue region 15 the gap between the impeller 6 and the inner contour 12 of the housing near the blow-out opening 14 is referred to as the tongue region 15.
the tongue area is wedge-shaped.
Fig. 3 shows the impeller 6 from the suction side.
the blades 8 on the lower part 7 can be seen through the opening 10 in the cover 2.
Fig. 4 again shows that the blades are 8 circular sections.
the base points of the radius of all circular sections lie on the circle 16.
the diameter of the circle 16 is 98 mm.
