Definitions

  • the invention relates to a device for separating water from the combustion air to be supplied to an internal combustion engine according to the preamble of claim 1.
  • a water separator which serves to separate water from an air stream in a flow channel, which is supplied to an internal combustion engine.
  • the water separator has in a housing a plurality of parallel Abscheidellamellen between which flow channels are formed.
  • the separator lamellae In order to redirect the air flow, the separator lamellae have a section offset in parallel, so that the inflowing, moisture-laden air impinges on the lamella wall at an angle and water droplets can accumulate on the wall.
  • the separated water is discharged via a collecting channel in the lower part of the water separator.
  • the object of the invention is to carry out, with simple design measures, a device for separating water from the air to be supplied to an internal combustion engine efficiently.
  • the device according to the invention is an air inlet device, via which combustion air is supplied to an internal combustion engine in a vehicle and which is designed to carry water, which is carried along in the approaching air is going to leave.
  • the device has in a housing a plurality of parallel Abscheidelamellen, between which flow channels for the air are formed. Furthermore, it is provided that the Abscheidellamellen are held at a pitch or opening angle in the housing.
  • the Anstell- or opening angle determines the size of the opening between adjacent Abscheidelamellen and thus the cross section of the running between adjacent Abscheidellamellen flow channels. Due to the Anstell- or opening angle, the fin surface of the inflowing air faces, so that the deposition is improved at the fins.
  • the pitch or opening angle refers to the housing level in which the Abscheidellamellen are stored or held.
  • the housing plane coincides with a vertical plane in which the vertical or perpendicular is located, with respect to which the separation lamellae are arranged below the angle of inclination.
  • the Abscheidelamellen are kept at a pitch or opening angle and fall on the upstream side to the outside, so that inflowing air between adjacent Abscheidellamellen under the Anstellt. Opening angle must flow upwards. Water droplets deposited on the lamellae partly flow directly over the lamellar surface, which improves the separation efficiency.
  • the Abscheidelamellen are preferably arranged obliquely in the housing and include an angle of inclination relative to the vertical or vertical, so that water, which attaches to the Abscheidelamellen, can flow through the inclined position Shen.
  • the Abscheidelamellen thus have a double inclination or inclination, on the one hand, the inclination with the inclination angle relative to the vertical and on the other hand, the pitch or opening angle relative to the housing level. Both angles support the deposition, wherein the Anstell- or opening angle increases the impact surface for zoom introduced, laden with moisture combustion air and the angle of inclination supports the discharge of the separated water from the Abscheidelamellen.
  • a version with vertical or horizontal standing Abscheidellamellen ie with an inclination angle equal to 0 ° or 90 °.
  • the Abscheidellamellen are expediently designed as in itself flat plates. Such Abscheidellamellen can be easily manufactured and mounted in the housing, on the other hand, the flow resistance for the zoomed-in air is not increased by deflections.
  • the inflow surface of the separation louvers may be expedient to make the inflow surface of the separation louvers curved in order to improve the dripping off of the separated water. In principle, however, a flat inflow area is sufficient.
  • the Anstellg. Opening angle of Abscheidelamellen is variably adjustable.
  • the Abscheidelamellen are pivotally mounted in the housing for this purpose, so that the pitch or opening angle is changed by an actuation about the pivot axis.
  • the adjustment of the setting or opening angle is expediently carried out with the aid of an actuator, for example an electromagnetic actuator, which adjusts the separating lamellae about the pivot axis in order to achieve the desired setting or opening angle.
  • all Abscheidelamellen are provided in the housing with the same angle of inclination, which is relative to the vertical, in particular in an angular range between 30 ° and 60 °, and preferably at least approximately 45 °.
  • the setting or opening angle can be in an angular range between 30 ° and 60 °.
  • the Abscheidelamellen can all have the same Anstell- or opening angle, with in principle also come into consideration, in which at least a portion of the Abscheidellamellen a different Anstellt. Have opening angle.
  • drainage channels are provided on the separation blades which extend parallel to the longitudinal extension of the separation blades and serve to drain off separated water.
  • the water discharge channels ensure safe removal of separated water droplets and prevent entrained water droplets are again entrained by the air flow and guided in the direction of the internal combustion engine.
  • the water drainage channels are preferably adjacent to the rear edge of the separation fins in the flow direction of the air and are formed, for example, as half-open channels which rise above the top of the separation fins.
  • the top of the separator louvers forms the impact surface on which the water is separated.
  • the separated water passes over the top of the slats to the rear water discharge channels and is discharged laterally in these. Due to the inclination of the Abscheidellamellen in the housing and the drainage channels are at the same inclination angle as the Abscheidellamellen, which has the advantage that the water flows through the gutters by its weight.
  • an at least substantially vertically extending water discharge duct is arranged on the housing laterally adjacent to the separation louvers.
  • This water discharge channel the water is supplied from the water discharge channels to the Abscheidellamellen.
  • the front end of the water discharge channels opens into the vertical water outlet channel or is in the immediate vicinity of the water discharge channel.
  • FIG. 1 is a perspective view of an air inlet device for the separation of water from the air to be supplied to an internal combustion engine, with a plurality of Abscheidellamellen in a housing of the device, which extend obliquely with respect to the vertical and are additionally held at a Anstell- or opening angle in the housing,
  • an air inlet device 1 is shown, is passed through the ambient air in an intake tract of an internal combustion engine.
  • the air inlet device 1 is located on a vehicle, for example in the lateral area of a commercial vehicle.
  • the direction of travel is marked "F.”
  • the air inlet device 1 has a plurality of deposition louvers 3 arranged one above the other in a housing 2, between which flow channels for bringing the combustion air in.
  • Part of the housing 2 is a rectangular frame 4, in which the separation louvers 3, the separation lamellae, as shown in FIG.
  • the separating lamellae 3 are additionally held at a setting or opening angle ⁇ in the frame 4 of the housing 2 and drop off on the inflow side to the outside.
  • the setting or opening angle ß refers to the plane 6 of the frame 4 of the housing 2, in which the Abscheidelamellen 3 are added.
  • the vertical 5 lies in the plane 6 or parallel to the plane 6.
  • the peripheral frame 4 has longitudinal sides which are at least approximately parallel to the vertical 5.
  • the frame 4 may have slightly curved sides and may have longitudinal sides and thus deviate from the vertical 5.
  • the inclination angle a under which the Abscheidellamellen are held in the housing is fixed and can not be changed.
  • the setting or opening angle ß may optionally be made adjustable by the Abscheidelamellen are pivotable along an axis which is parallel to the lamella longitudinal axis.
  • actuators may be provided, wherein optionally a common actuator for the common adjustment of the opening or angle of attack of all Abscheidellamellen is sufficient.
  • the upper side 8 (FIGS. 3, 4) of the separation lamellae 3 forms the inflow surface and faces the supplied air flow.
  • the water particles contained in the air stream are deposited on the upper side 8 of the Abscheidellamellen.
  • the water-discharge channel 7 is made in one piece with the respective Abscheidelamelle.
  • the water flow profile is shown in Fig. 4.
