Definitions

  • the present invention relates to an arrangement for supporting a fan housing which houses a fan impeller or fan wheel, wherein the exhaust end of the housing opens adjacent an opening in a wall of the space or room to be air-cooled.
  • the invention primarily relates to fan housings having a size which is normal with computer cooling fans and whose weight, including the electric motor incorporated in the fan, is about 70 grams for instance. Externally, the fan housing has a four-sided configuration, measur ⁇ ing 60 x 60 mm. The fan housings, however, may be larger in the case of larger computers with larger cooling re ⁇ quirements.
  • a housing of this kind is normally secured to a wall in the vicinity of a fan-housing opening with the aid of four screws which are screwed into screw-threaded holes provided in the wall.
  • the four screws represent a cer ⁇ tain material expenditure and a certain amount of time is also consumed in threading the screw holes and also in tightening the screws in said holes.
  • the most serious drawback with this known arrangement is that vibrations from the fan impeller and the electric motor propagate to the wall, via the screws, and therewith create disturbing vibration noise.
  • An object of the present invention is therefore to reduce these drawbacks to the greatest possible extent. This object is achieved with an arrangement having the characteristic features set forth in Claim 1.
  • the inventive arrangement is also cost-saving.
  • Figure 1 is a perspective view of a known fan housing positioned above an opening provided in the housing wall, prior to fitting the housing.
  • Figure 2 is a sectional view taken on a broken plane along the line 2-2 in Figure 1.
  • Figure 3 is a perspective view of a second embodiment of the housing with the housing shown in position above the wall opening.
  • Figure 4 is a sectional view taken on the line 4-4 in Figure 3.
  • FIG. 1 illustrates a known fan 10 having a cylin ⁇ drical fan housing with two end flanges 12, 14 which form lugs at the corners, which are connected through cylinders 16 for fastener screws (not shown) .
  • the impel ⁇ ler 18 of the blower or fan 10 is driven by a motor incorporated in the fan assembly.
  • the flanges impart a square shape to the fan components.
  • the corner parts 12A, 14A of the flanges 12, 14 form lugs or shoulders which extend radially in relation to the cylinders 16.
  • a wall 20, for instance a computer housing wall, is provided with a square opening which is sufficiently large to accommodate the fan housing with a given clear ⁇ ance.
  • a tongue or like element in the form of a hook 24 or some other like element is provided at each side edge of the opening.
  • the housing together with the flanges, fits in the opening and between the hooks 24 with a predetermined clearance 26.
  • FIG. 1 Shown in Figure 1 is a first elastic ring 28 which has a cylindrical cross-section, similar to the case of an O- ring, although it may also have a rectangular cross- section.
  • the ring 28 is shown stretched around the housing. In the illustrated embodiment, the ring bears against the cylinders 29 on the known housing.
  • FIG. 1 Also shown in Figure 1 is a second elastic ring 30 which is stretched and hooked around the hooks 24.
  • the rings can be fitted quickly and easily.
  • the second ring 30 is first hooked around the hooks 24, wherein those parts 32 of the ring that extend between the hooks will form an elastic support for the exhaust end of the housing when the housing is inserted down between the hooks.
  • the first ring 28 is then stretched out at four points and hooked on the hooks 24 so as to lie on the second ring 30 at the hooks, as shown in Figure 2, where the first ring is moved into abutment with the lugs or shoulders 14A so as to hold the housing pressed against the aforesaid parts 30 of the second ring.
  • the housing is therewith supported securely by the two rings 28, 30 in a position which is coaxial with the opening 22 and in a manner which will prevent axial movement of the housing in relation to the rings. Because the rings are chosen to produce a sufficiently strong holding force, the housing will remain in the position desired, even should the housing be subjected to axially directed forces, for instance as a result of bangs and knocks.
  • a highly simplified embodiment may consist of a cylindrical housing which is secured elastically between the two parts of an elastic ring stretched onto two diametrically opposed hooks. Although this embodiment functions satisfactorily, it is not normally sufficiently secure against shifting of the housing when, for instance, the housing is subjected to axial impact.
  • One important advantage afforded by the invention is that it can be applied immediately to generally existing fan housings without requiring changes to be made. The only modification required is the provision of the hooks adjacent the wall opening. Relatively inexpensive O- rings are conveniently used as the aforesaid elastic rings.
  • a fan can be provided at the exhaust end of the fan, or a pair of flanges to form a groove for coaction with the elastic rings.
