Definitions
- the invention relates to a heat exchanger with a Finned tube block, at its two parallel to the tubes extending sides, each with a side part made of elastic deformable material is provided, which the outer ends the ribs overlap U-shaped and by as locking elements trained barbs arranged in alignment with each other Recesses of the ribs are held, whereby the the barbs connecting web of the side parts convex to the ribs arched is in the installed state under bias to the Ribs rests.
- a heat exchanger with side parts of this kind is from the DE 196 05 909 A1.
- the block clamping but by shaking solve, especially when upstanding edges the bridge serve to accommodate additional parts that are not should lie next to the finned tube block.
- Heat exchangers of similar design are also known (FR-A-26 14 688), where the side parts are firmly attached to the ribs anchored. There, however, the side parts are formed in two parts and let each other so on the ends of the Push ribs that protruding hooks into appropriate Recesses of the ribs intervene. Both components of the Side parts are then interlinked by the mesh secured by locking hooks in the mounting position.
- FR-A-26 14 688 Heat exchangers of similar design are also known (FR-A-26 14 688), where the side parts are firmly attached to the ribs anchored. There, however, the side parts are formed in two parts and let each other so on the ends of the Push ribs that protruding hooks into appropriate Recesses of the ribs intervene. Both components of the Side parts are then interlinked by the mesh secured by locking hooks in the mounting position.
- Such Designs are complicated.
- the present invention is therefore based on the object a side part for a heat exchanger of the aforementioned Kind, in which case the later on the ends of the ribs resting connecting web for the barbs before assembly convex to the ribs is arched, so that a better holding stability of the side parts is achieved without a two-part training and thus an increased Installation effort is necessary.
- the outer web of the hollow profile acts in the mounted state as a pressure strut, which is a loosening of Barbs safely prevented.
- the locking element as a locking element with two elastically interlocking Projections may be formed, wherein the projections advantageous are formed as strips, one of which is elastic laminatedschreibbaren locking edges for engaging behind Paragraphs on the other bar is provided.
- This embodiment lets on the one hand, the production of the hollow section Extruding to, on the other hand arises in this way too a continuous locking of the two webs against each other within the hollow profile.
- the second bridge in the area the side walls a smaller thickness than in the remaining area and he can also in the area of the locking bar be a little weaker.
- This embodiment leads to a kind of hinge effect in the narrower trained Areas, so that the second jetty on both sides of the Center off, where his locking bar is arranged, so kink can be as in the area of the locking bar and in the area of Sidewalls hinges present, whereas the intervening Area is stiff.
- This embodiment therefore brings the The advantage with it, that during assembly in the installed state approximately rectangular cross section having hollow profile has two mutually weggewölbte longitudinal sides, the Collapsing the side walls and the rib ends across Allows thighs with the barbs.
- the invention is to achieve such Swinging effect during assembly advantageous if the side walls and the adjoining, the ribs across Legs are formed as stiff as possible with the barb.
- Fig. 1 shows a heat exchanger with a side part 1, which is extruded from an elastic plastic and for adaptation to the length of the heat exchanger not shown in detail Can be cut to length.
- This side part 1 is in accordance with Fig. 1 in the direction of the arrow 2 on the ends 3a of Ribs 3 are placed, in a manner not shown in detail form the finned tube block of a heat exchanger, the off a plurality of pipes not shown in detail is constructed, the run transversely to the mutually parallel ribs 3 and at their open ends in collection boxes, not shown lead. Parallel to the tubes extend the side parts 1, of which only one is shown.
- This one off a finned tube block formed heat exchanger is of a Cooling medium flows through the collecting tanks and the pipes, while in between the ribs 3 in known Way, air flows when the heat exchanger is e.g. as a cooler is used for a motor vehicle engine.
- Fig. 1 shows that the ribs 3 at their two Outside edges have recesses 4, which are inclined Form edges 4a, which are engaged behind by barbs 5 can be at the end of thighs 6 inward which are approximately at a right angle go over into a bridge 7, the convex facing him Ends 3a of the ribs 3 is curved.
- the bridge 7 goes laterally in upwardly facing side walls 8, which in turn connected by a second web 9 with each other are, with the web 7 and the two side walls 8 together forms a hollow profile.
- the web 9 is in its central longitudinal plane 10 with a continuous bar 11 with a provided mushroom-shaped cross-section. This bar 11 is located in State of Fig. 1 a from the first web 7 also from in the interior 12 of the hollow profile inwardly extending bar 13 opposite, which consists of two latching hooks 14, at their the mushroom head of the bar 11 opposite side with a Insertion slope are provided.
- this side part 1 is pressed in the direction of the arrow 2 on the ends 3a of the ribs 3, wherein the legs 6 under another bulge of the web 9 bend laterally and elastically in the Snap recesses 4. Is this first assembly position reached, then continues in the direction of the arrow 15 of FIG. 2 pressed on the upper bridge 9 until this upper bridge 9 and the lower web 7 by resting on the ribs 3 in a move about parallel to each other running position, the Mushroom head of the bar 11 between the two locking hooks 14 is pressed is and of these latching hooks, as shown in Fig. 2, is engaged behind.
- the hollow profile of the side part 1 has Therefore, in the mounted position of FIG. 2 approximately rectangular shape on; the pre-assembly still existing bulge of the webs 7 and 9, which were arched in opposite directions, is no longer available.
- the second web 9 acts in the mounting position of FIG. 2 as a compression strut, the pivoting back of the legs 6 and the side walls 8 in the position of FIG. 1 prevented.
- the second web 9 each in the region of its center and the side walls 8 each has a thickness a or b, which is smaller as the thickness c of the web 9 respectively in the area between them Edge regions to the side walls 8 (thickness a) or to the Locking bar 11 (thickness b).
- the Hollow profiles for the side part 1 is also appropriate make sure that the wall thickness d of the side walls 8 and the wall thickness e of the legs 6 with the barbs 5 as possible is made large, so here if possible a Rebounding from the mounting position shown in FIG.
