Definitions

  • the invention relates to a device for fastening an additional part, in particular a fan cover to a heat exchanger according to the preamble of claim 1.
  • Heat exchangers for motor vehicles, in particular coolant radiators often have a fan cover, which is held on the coolant radiator by means of fastening means and with its frame encases a fan, which promotes ambient air through the radiator.
  • the fastening means are often designed as latching, snap or clip connections, the parts of which are molded onto the fan cover and to manifolds of the heat exchanger, d. H. are integrally formed with these parts made of plastic.
  • a coolant radiator has been known with a fan cowl, which is connected to the coolant radiator by latching means.
  • the latter are molded partly in one piece on the fan cowl made of plastic and molded in part on the likewise formed in plastic water tanks of the radiator.
  • the fan cover is attached to the rear of the radiator during assembly and pressed until the locking means lock together and form a latching connection.
  • the release of the fan guard takes place in the reverse direction, ie when installed in the motor vehicle Coolant cooler - in the direction of the engine. For this purpose, appropriate space is required, which is not always available.
  • the applicant has been known a cooling unit for an internal combustion engine, in particular in a motor vehicle, wherein a fan cowl with a coolant radiator is connected by molded onto the water boxes or the fan cover fastening means. On the fan cover laterally projecting support arms are molded, which are hooked into hook-shaped suspension lugs on the water tanks.
  • the fan guard can thus be mounted from top to bottom, ie attached to the coolant radiator and dismantled in the reverse direction. Problems can arise if, with laterally arranged coolant or water tanks, inlet or outlet nozzles and / or coolant hoses are arranged in such a way that they obstruct or make impossible the removal of the suspended fan shroud.
  • the fastening means are at least partially formed as a releasable holder.
  • the advantage is achieved that bulky fastening means that impede disassembly of the fan cover can be removed before removing the fan cover, so that the dimensions of the fan cover, in particular in the width are reduced so that the part to be removed also between coolant nozzle and / or coolant hoses or similar obstacles can be passed and removed.
  • This also results in the advantage that existing fan cowls, ie, the corresponding injection molds can be maintained, with only the bulky molded fasteners are replaced by the releasable holder according to the invention.
  • the fan cowl or another accessory can be attached directly to the coolant radiator or its coolant boxes by means of the detachable holder or - indirectly - on so-called Modulträgem which receive the heat exchanger or coolant radiator and supported against the vehicle. Except with detachable holders advantages with movable, preferably displaceable and / or pivotally arranged holders can be achieved.
  • the releasable holder are arranged in pockets, which are preferably located laterally on the fan guard.
  • the holder in this case have a flat plug part, which is inserted into the correspondingly formed pocket and fixed there, for example by means of a self-tapping screw.
  • the releasable holder on a support arm, which is supported in a cooler-side tab, d. H. is hung from top to bottom.
  • the detachable holder thus have the same function as the known molded, integrally formed with the fan cover holder, but can be easily removed, if necessary, insbesondre during disassembly of the fan cover.
  • the releasable holder are also designed as plastic pointed parts and thus inexpensive to produce.
  • one or two holders according to the invention are provided on each side of the fan cowling at laterally arranged coolant boxes (cross-flow coolers).
  • the upper and lower sides of the fan cowl can be connected to the coolant radiator with conventional fasteners.
  • Fig. 1 shows a coolant radiator 1 with a laterally, ie, approximately vertically arranged coolant box 2 and attached to the coolant radiator 1 fan cover 3.
  • the coolant radiator 1 is formed as a cross-flow cooler and has a second coolant box, not shown.
  • the left coolant box 2 is preferably made of plastic and has in its upper region on a coolant inlet nozzle 4, to which a coolant hose 5 is connected.
  • a hook-shaped, upwardly open suspension lug 6 is provided on the coolant box 2, which serves for fastening the fan cowl 3.
  • a tongue-shaped locking element 6a is provided on the suspension lug 6.
  • the fan cowl 3 is attached to the radiator 1 by means of a detachable holder 7, which is hooked on the one hand into the suspension lug 6 and on the other hand is inserted in a pocket (not visible here) in the fan cowl 3.
  • An analog attachment of the fan cover 3 on the radiator 1 is provided on the other side, not shown.
  • the fan cover 3 has a frame 3a, within which a fan 8 rotates.
  • the latter is part of a fan 9, which is connected via struts 9a with the fan cowl 3, in particular its frame 3a.
  • the fan cover 3 carries the entire fan 9 including fan 8.
  • the fan cover 3 is preferably connected via other not shown conventional fastening means on its upper and its lower side with the coolant radiator 1, preferably its side parts, not shown - corresponding fasteners are from the aforementioned Known in the art.
  • Fig. 2 shows the releasable holder 7 Fig. 1 in the assembled state with the fan cover 3 - without the Ein distresslasche 6.
  • the fan cover 3 has a pocket 10, in which the holder 7 is inserted and fixed by means of a screw 11 with self-tapping thread.
  • the holder 7 has a protruding from the pocket 10 holding arm 7a with a stop 7b, which is hooked into the hanger 6, not shown here.
  • Fig. 3a shows the holder 7 as a single part, ie in a state prior to assembly or after its removal from the pocket 10 (see. Fig. 3b ).
  • the holder 7 has a relative to the support arm 7a widened, flat plug part 7c with several in the insertion direction approximately parallel extending ribs 7d on.
  • the middle rib 7d has an eye 7e which serves to receive the securing screw 11.
  • the holder 7 is produced in one piece as a plastic injection molded part.
  • Fig. 3b shows the bag 10 with locking screw 11, wherein an inlet opening 10a can be seen, which is adapted to the cross section of the plug part 7c of the holder 7 and also has ribs 10b, which are arranged offset laterally relative to the ribs 7d of the plug part 7c.
  • Fig. 4a shows the holder 7 in a view from the rear, ie from the opposite side, as in Fig. 3a shown.
  • the illustrated side of the plug part 7c is smooth - in contrast to the ribbing in Fig. 3a
  • the stop 7b is formed as a flange which extends over a narrow and a longitudinal side and the fixation of the fan cover 3 relative to the in Fig. 1 illustrated hanger 6 serves.
  • Fig. 4b shows the insertion opening 10a of the bag 10 with two extending in the direction of insertion ribs 10b, which are in the assembled state of the holder 7 between the ribs 7d.
  • the holder 7 are inserted with their plug-in parts 7c in the pockets 10 of the fan cover 3 and fixed by means of the locking screw 11. They are thus form-fitting and rattle-free attached to the fan cover 3 and act as retaining arms or fasteners.
  • the fan cover 3 is then - from top to bottom - used in the suspension lugs 6, wherein a fuse is effected by the locking element 6a, which blocks a movement of the retaining arm 7a upwards.
  • the stops 7b cause a fixation of the fan cover 3 in the lateral direction.
  • the locking screw 11 is released, the locking element 6a pushed back to release the retaining arm 7a and the holder 7 removed from the bag 10.
  • the fan cover 3 can be removed upwards.
  • pulling out the fan cover 3 upwards would not be possible since the holder would be blocked by the coolant connection 4 or the hose connection.
  • the invention is not limited to the above-described plug-in holder, but is also a movable, d. H. displaceable or pivotally mounted on the fan guard holder in the invention.
