  • the end platev 18- is. fixed. to a pair; of studs 20: which; extend to andarerfixed to the side wall. 17,1and1-the end. plate 19 is located within the impeller 1.
  • This impeller 1 is coaxial with the cylinder in which the guides are located, and the blades of the impeller are carried by a pair of rings 21 and 222 which areslidable on the peripheriesof the end plates 19 and 18, respectively, so that these end plates form bearings for the impeller.
  • the ring 21 is in the form of an annular flange integral with a plate 23 fixed .to a shaft 24 which extends through side wall 16 of the casing 15 and which is turnably supported by the side wall, a pulley 25 or the like being fixed to the shaft 24 so that in this way impeller 1 may be driven.
  • Fig. 2. shows a fan identical with that of Fig. 1 except that the interior of the space surrounded by the impeller is provided, in addition to the guide 3, with a single guide and a plurality of stationary vanes 11, as indicated in Fig. '2, the guides of Fig. 2 operating in the same way as the guides of Fig. 1 to direct the air across the space surrounded by the impeller.
  • Figs. 4-6 show a preferred construction of a fan in accordance with the present invention.
  • the fan disclosed therein includes a casing 30 in which the impeller 31 is supported for'rotation.
  • the impeller 31 is carried for rotation by the side walls 32 of the casing 30.
  • the impeller includes a pair of circular, coaxial, end plates 33 each of which is fixed to a shaft 34 extending outwardly through an opening in a side wall 32 to be turnably supported by the casing 30.
  • the casing 30 is provided with an inlet 37 which converges as it approaches the impeller 31 and with an outlet 38 which diverges as it leaves the impeller 31. Furthermore, it'will be noted that, as was the case with the embodiment of Fig. l, the angle through which the inlet 37 extends about the axis 39 of the impeller is larger than the angle through which the outlet 38 extends about this axis.
  • the inlet and outlet ducts each communicates with the rotor at the periphery thereof over an angle of at least 90, as is evident from Fig. 4.
  • Fig. 4 shows a fan where the outlet 38 extends in general along a direction, taken at random, parallel to the plane 40 passing through the axis of the impeller, and the inlet 37 extends in a direction parallel to the horizontal plane 41 shown in Fig. 4.
  • Fig. 4 shows a fan where the outlet 38 extends in general along a direction, taken at random, parallel to the plane 40 passing through the axis of the impeller, and the inlet 37 extends in a direction parallel to the horizontal plane 41 shown in Fig. 4.
  • each of the blades 42 itself forms part of a cylinder. It is preferred to provide 36 blades on the impeller so that the blades are spaced from each other by 10, and the cylinder of which each blade forms a part has a radius 43 which is approximately as long as the distance between each pair of adjacent blades, the center of radius 43 being located between the inner and outer cylinders 44 and 45 in which the inner side edges and outer side edges of the blade 42 are respectively located.
  • each blade 42 is curved in the direction of rotation of the impeller.
  • each blade 3 42 may make an angle of between 25 and 40 with a tangent to the cylinder 45, as shown in Fig. 4.
  • the particular angle made by the outer side edge of each blade with the outer cylinder 45 is not particularly critical as long as it is somewherebetween 25 and 40.
  • actual fans constructed in accordance with the present invention and operating very successfully have had angles at the outer side edges of the blades, respectively with the cylinder 45 of 26 and also of 38.
  • the angle of the inner side edge of each blade with a tangentto the cylinder 44 is always 70' or very close thereto.
  • the casing 30 includes a wall portion 46 extending from the inlet to the outlet and an opposite wall portion 48 extending from the inlet to the outlet.
  • the wall portion 46 is located closely adjacent to and corresponds closely to the curvature of the cylinder. 45. It has been found best to terminate the wall portion 46 at its inlet end at a distance of 0.9 from the plane 40, as indicated in Fig. 4, and the wall portion 46 merges beyond this point with the part of the casing 30 which forms the inlet 37.
  • the opposite end of the wall portion 46 is preferably formed along a curve having aradius of approximately 2.4, the center of this radius being located at a distance of approximately 0.9 from plane 47 which is normal to the plane 40 and at a distance of-0.5 from the plane 40, as shown in Fig. 4. Furthermore, it will be noted that the top wall of the outlet 38, as viewed in Fig. 4, is located in a plane which is perpendicular to the axis 47.
  • a particular feature of the invention resides in the configuration of the wall 48 of the casing 30.
  • This wall 48 has a radius of curvature slightly less than 1, such as, for example, 0.9. Furthermore, this radius has its center spaced by 0.2 from plane 40 and 0.6 from plane 47, as shown in Fig. 4. It will be noted that wall portion 48 thus has its end portion next to the inlet 37 located nearer to the axis 39 than its end portion next to the outlet 38, and as a result the wall portion 48 forms with a cylinder 45 a gap which converges as it approaches the inlet 37.
  • the impeller 31 when driven in a clockwise direction, as viewed in Fig. 4, creates a whirling body of air 49 indicated in dot-dash lines in Fig. 4.
  • This whirling body of air acts in the same way as a solid guide of thetype shown in Figs. 1 and 2 so that it is possible to eliminate such solid guides with the construction shown in Fig. 4.
  • the whirling body of air 49 which moves continuously in a clockwise direction, as the impeller itself rotates in a clockwise direction, does not in any way interfere with the air passing through the fan and serves to guide this air in the same way as the solid guide would.
  • the radius of the inner cylinder 44 may be 1', or 6", or 2', or any other desired dim'ension depending upon the conditions tobe met by thefarn- It-is-on1yimportanf that the several parts of the fan have the relationshipsindicated in'Fig. 4 and described above, and evenhereall' of these relationships are approximate.
  • theradius-of curvature of the wall portion 48 should be' -equal to the dist-ance between the plane 47 and-the'center of the. radius of curvature of the-endportiomof wan: 30 next td the outlet 38.

  • Figs. 7-9 further show diagrammatically the motor 15 which drives the impeller through the belt 51. Any suitable means may be provided to adjust the tension of the belt 51.
  • the walls of the casing 30 which are next to the impeller conform to the above requirements.
  • Fig. 10 shows an arrangement where the casing 30! is shaped so as to direct the air issuing from the fan at an angle of 45 with the air entering the fan.
  • Fig. 11 shows an arrangement where the casing 300 is shaped to direct the air leaving the fan in a direction which makes an angle of 0 with the air entering the fan, and
  • Fig. 12 shows an arrangement similar to that of Figs. 7-9 in that the air is deflected through 90 by the casing 30d after passing through the fan. However, it will be noted that the air enters and leaves the casing 30d at an angle of 45 with respect to a horizontal plane.
  • the fan of the invention which may be called a cross flow fan, produces far less noise at a given speed of rotation than either a radial oraxial flow conventional fan operating at the same speed of rotation.
  • the fan of the invention may have its impeller located directly within a duct, so that very little space is required for the fan of the invention.
  • the impeller may be made of any desired length, since the length of the impeller in no way influences the operation of the fan of the invention.
  • it is only necessary to change the speed of rotation of the impeller accordingly.
  • the fan of the invention there are no operating characteristics which change suddenly at two speeds of operation which are close to each other. In other words, when increasing or decreasing the speed of rotation of the fan of the invention there is no danger of passing through certain critical speeds as is the case with known fans.
