Definitions

  • the present inventin relates to an installation for the cooling of internal combustion engines, with a fan driven by the internal combustion engine possibly by way of an engageable and disengageable coupling, especially by way of a coupling controlled in dependence on the temperature, which is arranged between the radiator and the internal combustion engine.
  • the cooling fan is arranged almost always directly in front of the entire engine block since normally little space is avaiable in the engine space. This has as a consequence with the customarily utilized axial fans that the engine block prevents a free discharge or flowing off of the supplied cooling air.
  • the fan therefore practically supplies only within the area of its blade tips whereas further inwardly hardly an air flow is produced for the reasons described above. Consequently, the en tire radiator surface which exists is utilized only very incompletely.
  • the present invention is concerned with the task to solve this problem.
  • the present invention solves the underlying problem with the arrangement of the aforementioned type by the use of a s'o-called halfor semiaxial fan with a conical hub strongly increasing in the direction toward the engine and with essentially straight blades, which rotates within an outer casing ring or shroud secured at a conventional radiator or radiator mounting.
  • the installation according to, the present invention offers the advantage that on the discharge side the supplied cooling air is now supplied by means of the fan shape as proposed by the present invention into that portion of the engine space, which is kept free from the engine itself. As a result thereof, a considerably improved discharge or outflow and consequently alsoa better efficiency of the fan will result.
  • the radiator will therefore be utilized considerably more efficiently in its entire cooling surface.
  • the hub of the fan rotor has an inclination of about 45 which remains constant over the entire axial blade width. Furthermore, itis proposed in accordance with the present invention that the outer casing ring overlaps or covers the blades in their axial extension to about 60 to 70 percent.
  • the casing ring itself can therefore-as customary-be constructed cylindrically; however, the present invention prefers a solution according to which the casing ring, as seen in the axial cross section, is conically enlarged like the hub in the same direction though more weakly.
  • a further feature of the present invention resides in that the hub is bent back bulge-shaped at its side facing the radiator, as viewed in cross section, and passes over into a securing flange; With the aid of this securing flange, the hub is then connected with its drive, i.e., possibly with the driven side of the fan coupling. It is additionally proposed that the fan rotor includes approximately 12 blades which-as viewed in the axial direction-partially overlap one another.
  • Another object of the present invention resides in an installation for cooling motor vehicle internal combustion engines which increases the cooling efficiency as well as makes possible an efficient use of the entire radiator.
  • a further object of the present invention resides in an installation for cooling motor vehicle internal combustion engines which renders more effective the discharge of the cooling air from the cooling fan.
  • FIG. 1 is a schematic side view of the over-all arrangement of the cooling installation according to the present invention
  • FIG. 2 is a side elevational view, partially in cross section, of the fan rotor
  • FIG. 3 is a partial end elevational view of the fan rotor indicating the blade form.
  • a fan coupling generally designated by reference numeral 11 of any conventional construction is secured at the engine block 10, which is driven in a conventional manner by the engine by way of a V-belt 12.
  • a fan rotor 13 is mounted on the driven side of the fan coupling 11, which rotates within a casing ring 14 that is secured at the radiator 15 or at the radiator mounting.
  • the fan rotor 13 is constructed as semi-axial fan so that the air flow takes place approximately along the steamlines l6, i.e., correspondingly displaced toward the outside. Consequently, the engine can no longer impair the free discharge of the cooling air so that, viewed from an over-all point of view, a better flow and, consequently, a better and more effective cooling can be achieved.
  • the fan rotor 13 has a relatively large spacing from the casing ring 14 in order that its blade tips do not strike the casing ring 14 when the engine carries out relative movements with respect to the radiator.
  • the fan rotor includes a strongly conical hub 17 whose diameter increases in the direction toward the engine and which has a constant inclination of about 45 over the entire width of the blades 18.
  • this hub 17 passes over bulge-shaped into an annular flange 19 by means of which it is connected at the fan drive, i.e., with the output of the fan coupling 11.
  • the blades 18 which number altogether 12, are constructed essentially rectilinearly.
  • the blades 18 are extended along the front edge 20 thereof toward the tips in the direction toward the radiator.
  • the outer contour of the blades 18 is constructed approximately angularlyshaped whereby the blade tip 21 is disposed in front of the center of the entire blade width, i.e., therefore in a direction toward the radiator.
  • the blades l8-as viewed from the fan overlap one another to an extent which is not insignificant.
  • the casing ring 14 I does not cover the blades 18' over the full width thereof but rather approximately to an extent of about 60 to percent in order that the outlet or discharge of the channels formed between the hub and the casing ring as well as the blades does not become excessively narrow in the direction toward the discharge
  • the casing ring 14 it is also possible to construct the casing ring 14 not cylindrical but possibly conical and more particularly with the same tendency as the hub 17 through with a considerably weaker or lesser inclination.
  • outer casing means covers the blade means in their axial dimension approximately to about 60 to 70 percent.
