Definitions

  • the invention relates to a rubber-elastic mounting frame for fastening an axial fan on the wall of a device housing with the features specified in the preamble of claim 1.
  • DE 32 10 164 02 discloses a holding frame made of elastic plastic material for mounting an axial fan in an opening in a housing wall, with the aid of which an electrical circuit accommodated in the housing is cooled.
  • This rectangular mounting frame has locking lugs projecting outwards on opposite sides, with the aid of which it locks on the opposite edges of the wall cutout.
  • the rectangular fan housing sits within this frame and is held there with resilient locking fingers.
  • a rectangular rubber frame for fastening an axial fan in a housing wall which has on one side a flange-like peripheral edge protruding in the axial direction, which surrounds its mounting flange when the fan is inserted, and engages around it at individual points with nose-like projections.
  • this rubber frame has a circumferential groove, which receives the edges of the mounting opening provided in the housing wall.
  • the invention has for its object to provide an easy to manufacture and assemble rubber-elastic mounting frame for an axial fan, which the transmission of Vibrations during operation of the fan on the housing wall of the device to be cooled effectively dampens and thus prevents disruptive sound radiation from the housing walls.
  • Figure 1 is a perspective view of a mounting frame according to an embodiment of the invention seen from the fan side.
  • Figure 2 is a perspective view of the frame of Figure 1 seen from the housing side.
  • FIG. 3 shows a cross section through the frame according to FIGS. 1 and 2 inserted into a housing wall with a protective grille attached;
  • FIGS. 1 and 2 shows a bottom view of the frame according to FIGS. 1 and 2;
  • Fig. 5 is a section along the line A-A through the frame of Fig. 4;
  • Fig. 6 is a section along the line B-B through the frame of Fig. 4;
  • FIG. 7 shows a detail of the part from FIG. 6 encircled by dashed lines.
  • the frame according to the invention preferably consists of a rubber material of suitable strength on the one hand in order to To ensure re mounting of the axial fan in the housing wall, but on the other hand sufficient softness to prevent vibration transmission from the fan to the housing wall.
  • the frame has a peripheral edge 2, on one side of which bearing segments 4 are formed in the area of the corners and on the other side a holding edge 6 is formed.
  • An axial fan not shown here, sits with its mounting flange within the peripheral edge, the inside width of which corresponds to the thickness of the mounting flange, so that the contact segments 4 and the holding edge 6 abut the mounting flange on both sides and hold the fan in this way.
  • a mushroom-shaped projection 10 which is used to fasten the frame to a housing wall, which for this purpose is provided with corresponding openings which are arranged outside the main opening for the air flow generated by the fan and if desired, can pass into this in the form of a slot in order to facilitate the insertion of the projections 10.
  • Each projection 10 has a foot 12, the length of which is dimensioned in accordance with the thickness of the housing wall to which the fan is to be attached.
  • the head 14 of the mushroom-shaped projection 10 is frustoconical in order to be more easily brought through a fastening hole.
  • the diameter of the Fastening hole corresponds to the diameter of the foot 12 to exclude displacements of the frame relative to the housing wall.
  • the projections 10 are penetrated by axially extending bores 16, which serve to fasten a cover grille, as will be explained in connection with FIG. 3.
  • peripheral edge 2 continues in the form of mounting brackets 18, which make it easier to pull the frame over the mounting flange of the axial fan.
  • FIGS. 1 and 2 it can also be seen in FIGS. 1 and 2 that the sides of the essentially square mounting frame — in the unassembled state — are curved outwards somewhat in a barrel shape and accordingly the air opening 20 does not have a circular circumference, but rather in the area of the four corners of the frame. has potential sections 22.
  • the frame is pulled onto the mounting flange of the fan, the corners are pulled outwards and the material is stretched so that the frame takes on the square shape of the mounting flange in the assembled state and the above-mentioned bulges on the sides disappear.
  • the air opening 20 is then approximated to the circular shape. The effort of the material to return to its original shape further improves the hold of the fan.
  • part of the housing wall 24 is shown to illustrate the fastening of the mounting frame.
  • its mounting flange is seated in the groove 28, which is formed by the contact segments 4, the inner wall of the peripheral edge 2 and the holding edge 6. With its surface facing the housing, the fastening flange rests on the knobs 8 instead of touching the contact segments 4.
  • a protective grid 30 is also shown, which is inserted with pins 32 in the bores 16 of the mushroom-shaped projections 10 and is fixed in the elastic rubber material of the frame due to a barbed surface of the pins 32.
  • FIGS. 4, 5 and 6 show the design of the parts explained in connection with FIGS. 1 to 3 even more clearly.
  • FIG. 7 illustrates the design of the mushroom-shaped projection 10 projecting away from the contact segment 4 with its base 12, the frustoconical head 14 and the bore 16.
  • the flat shape of the knobs 8 can also be seen more clearly here.
