Definitions

  • the invention relates to a cooling device with an axial fan in a capsule design.
  • the object of the invention is to provide a cooling device with an axial fan in a capsule or apron design, in particular for a vehicle engine in which a backflow of part of the conveyed air in the axial fan is avoided with the aid of simple structural means.
  • the object on which the invention is based is achieved by a fixed baffle plate on the outlet side of the axial fan in the area of the fan hub.
  • the baffle plate expediently has a capsule or apron-fixed fastening device which can be adjusted in the axial direction of the fan, and the baffle plate is preferably divided into two or more parts, for example in segment form.
  • the circumference of the baffle plate can have at least one flat and / or a conical or dome-shaped cross section.
  • a planar section is expediently combined with a conical or dome-shaped section in such a way that the planar section lies at the radially inner point of the baffle plate and the conical or dome-shaped section practically adjoins at the radially outer point.
  • the baffle plate is preferably circular on the outer peripheral edge, it can also have a polygonal or polygonal shape.
  • any suitable material with sufficient dimensional stability and temperature resistance can be used as the material of the baffle plate.
  • baffle plate that is basically the same structure can be used for different fans.
  • the most favorable flow conditions are determined by practical experiment.
  • the invention therefore fixes the baffle plate to a fixed part of the capsule, the apron, the fan or the motor, preferably by means of a holder which enables the baffle plate to be set as close as possible to the fan edge.
  • the stationary or stationary baffle plate does not cause any additional forces on the fan drive (dead weight, unbalance, inertia when accelerating or decelerating).
  • the plate can be built comparatively lightweight, since no centrifugal forces act on it during operation. Strict rotational symmetry of the baffle plate is not necessary according to the invention since the unbalance is not important.
  • a divisible baffle plate advantageously enables retrofitting without changing the actual fan.
  • the cooling device 1 of a motor vehicle engine which is of no further interest is encapsulated or shortened in a manner of no further interest for reasons of noise reduction and essentially consists of a cooler 6 and an axial fan 2 arranged downstream in the flow direction, the cooler 6 and the axial fan 2 being circumferentially provided by a conical one Connection shaft 7 are interconnected.
  • the axial fan 2 is driven by a drive shaft 5, the end of which faces the cooler is connected to the fan hub 4 in a rotationally fixed manner.
  • a non-rotatable baffle plate 3 which in the exemplary embodiment of the drawing is designed as a flat circular disk with a central opening through which the drive shaft 5 extends without contact.
  • the radial extent of the baffle plate 3 is such that a backflow of the conveyed air in the area of the blade roots of the axial fan 2 is largely avoided, with the aid of a simply constructed fixed part, which does not necessarily have to have rotational symmetry and can also be retrofitted in cooling systems , especially if it is made up of several parts.
