Definitions
- the right-hand heat protection areas can be designed approximately in accordance with the left-hand heat protection areas.
- the cross-flow fans according to these exemplary embodiments of FIGS. 3-5 can correspond to the cross-flow fan 40 according to FIG. 2, with the exception of the differences explained below which only concern the heat protection means.
- the intermediate disk 53 'of the impeller 46 delimited on the left side by the conveying area 52 of the cross-flow fan is a gas-impermeable disk, which therefore has no air passage openings .
- a labyrinth seal 74 is also provided which encompasses the circumference of the impeller 46 at the transition region from the conveying region 52 to the relevant extension region 48 'of the impeller 46, which, in addition to the outer circumferential region of the intermediate disk 53', also through the outer circumferential region of one arranged close to it formed as a gas-impermeable washer 75 and formed by arranged on the inner periphery of the housing 41 washers 76, one washer 76 engages in the space between the two washers 53 ', 75 and the other washer 76 is arranged on the left side of the washer 75 near it .
- FIG. 5 shows a variant of the section of the cross-flow fan according to FIG. 4.
- the interior of the cup-shaped bulge 45 ' is divided by additional sealing rings 80, 81 on the housing and on the impeller, as shown, into two chambers 82, 83, essentially sealed off from one another, arranged axially one behind the other, of which the left end Cooling air can flow through chamber 83, which is conveyed by the section 50 ′ of the blade ring of the impeller 46 located in this chamber, in that this section 50 ′ sucks in cooling air like a radial impeller and conveys it radially outward, thereby providing additional heat protection for the left-hand plain bearing bush 65 shown is effected.
- a corresponding air cooling can also be provided in the other cup-shaped housing bulge on the right-hand side.
- the cooling air described is not a conveying gas in the sense of the invention, since it only serves to cool the fan and is not the conveying gas to be conveyed by the fan from the suction opening 42 to the exhaust opening 43.
