Definitions
- Radiator in particular radiator for vehicles
- the present invention relates to a radiator, in particular a radiator as used in vehicles and is preferably integrated into the cooling circuit for an internal combustion engine.
- Such coolers are usually designed as so-called tube coolers, in which, between two preferably vertically aligned headers, cooling tubes extending parallel to one another extend in the longitudinal direction. In this case, a flow of a coolant from a manifold through the cooling tubes to the other manifold takes place.
- a heat exchange with a tube extending in the transverse direction of the extension, that is to say the width of the cooler, and flowing, preferably gaseous cooling medium, such as ambient air.
- the corrugated ribs are, in particular, a corrugated narrow sheet-metal strip whose ridgelines extend in the direction of the width of the radiator and which are held fixed alternately along the ridgelines on a lower or upper cooling tube, in particular by brazing connected to the cooling tubes.
- each corrugated fins there is known to provide above the uppermost and below the lowest cooling tube of the radiator also each corrugated fins.
- a side plate on at least one of the sides extending parallel to the cooling tubes and across the width of the radiator. It is known that side plates have the disadvantage that they are given a different thermal expansion in the longitudinal direction of the cooling tubes due to a different thermal expansion behavior and due to the fact that they are in a different temperature range than the cooling tube. Due to this different thermal expansion, strain loads occur, in particular on the outer cooling tubes, which can lead to leaks in the cooler over a number of thermal load cycles, in particular in the root area of the outer cooling tubes.
- the object of the invention is accordingly side plates in such a way that such damage to the radiator can be reliably avoided.
- a radiator as it serves in particular as a radiator for vehicles, has two extending in the vertical direction manifolds.
- the headers are fluidly connected to one another in the longitudinal direction via cooling tubes running parallel to one another.
- Wellen ⁇ ridges are arranged between the cooling tubes, the ridge lines extend in the direction of the width of the radiator and alternately abut each other on both sides of a cooling tube.
- at least one side plate is provided, which extends on the outside between the collecting tubes parallel to the cooling tubes and in its width corresponds substantially to the width of the corrugated ribs.
- the at least one side panel has areas weakening adjacent to the headers.
- the disadvantage can be compensated that due to Montagemanipulationen and manufacturing tolerances attaching the corrugated fins on the cooling tube or when attaching the side plate on the corrugated ribs in the region of the peripheral corrugated ribs, for example by pushing together the corrugated ribs and a slight excess of solder during soldering , a blocking of the corrugated fins is ent, so that in the region which is adjacent to the headers, an increased rigidity of the corrugated fins is given in terms of the longitudinal extent.
- the material weakening consists in a reduction of the width of the material of the side plate in the region adjacent to the collecting tube.
- the high flexibility and low rigidity of the side part is generated in particular in the area in which otherwise the highest load transfer from side plate to cooling tube via the corrugated fins takes place.
- the reduction of the width of the material is formed such that the side plate has on at least one side a continuous, linear side edge in the longitudinal direction of the radiator. By this side edge, for example, a straight, linear front or rear end of the radiator plate is created, which is not changed by a reduction of the cross section in its contour. This measure creates in particular a defined outer contour of the radiator, for example, in view.
- the side plate is formed in the region of the material weakening from a small number, for example up to five narrow material fingers.
- each of the material fingers is a narrow web of material, which protrudes from a base body of the side panel in the direction of the collecting pipe and extends as far as the collecting pipe, relative to the width of the side strip.
- the material finger towards the last crest of a wave rib.
- the formation of narrow material fingers enables a soft design of the side plate in the area of the fingers. In this case, it can be provided in particular that in each case a finger is formed marginally, so that an outwardly continuous side edge of the side plate is created.
- the number of material fingers must be determined according to the requirements of rigidity and flexibility.
- stiffeners which consist of an elevation in the profile formation in the vertical direction.
- carrier-like stiffeners are created, which mainly increase the power and load absorption in the vertical direction of the material weakening area.
- an intermediate region of the side plate is provided, which is opposite to the weakening surfaces in the longitudinal direction inwardly offset from the headers away.
- the intermediate region of the side plate consists in a deflection which has a ridge line extending in the width of the side plate.
- the at least one side plate is fastened exclusively to corrugated ribs, in particular connected thereto by brazing.
- the exclusive fastening of the side plate to the corrugated ribs avoids a connection of the side plate with the collecting tubes, so that in this area there is no stiff support from the side plate to the collecting tubes, which leads to stresses due to different thermal expansion. without the adjacent cooling tube leads, which are transmitted by a wave plate ü-.
- the corrugated sheet is so stored against the headers floating on the ridgelines of the corrugated ribs.
- the side plate does not extend directly to the headers, but is spaced from them by a gap.
- this gap serves as expansion space for the side panel in the longitudinal direction and, on the other hand, it prevents forces from the side panel from being introduced into the adjacent cooling tube via the last flanks of the corrugated fins and forces are introduced at the base of the header which could lead to leakages of the cooler.
- the gap has a gap width which extends over a number of periods of the corrugations of the corrugated sheet, that is, over a certain number of corrugations of the corrugated sheet.
- the number of ridge lines is preferably below 20 and in particular between 5 and 15.
- Figure 1 in a 3D view of an extract from a erfindungsge ⁇ according trained radiator

- Cooling tubes 12 extend in the longitudinal direction between two header tubes 11, with corrugated fins 13 each being arranged between two cooling tubes and having ridge lines 14 which run in the direction of the width B of the cooler.
- the ridge lines 14 of the corrugated fins are each in contact with a cooling tube 12 arranged above and below and connected thereto by soldering.
- the side plate 40 is attached to the upper side, this being connected in particular by soldering to the ridgelines of the corrugated ribs 13.
- the side plate has a width b which essentially corresponds to the width B of the cooler and the corrugated ribs 13.
- the embodiment of Figure 1 shows an embodiment in which in a region 49 which is adjacent to the manifold 11, the side plate is weakened in its rigidity that the So ⁇ sheet only consists of two material fingers 43, which extends up to the in ⁇ nenindustrial edge of the manifold 11, which is in particular designed as a tube bottom 15, reaching.
- the two material fingers 43 are arranged so that they are offset inwardly with respect to the outer side edge 42 of the side plate.
- FIGS. 2a to 6b show in schematic diagrams different embodiments of side plates according to the invention, wherein in each case the FIGS. 2a, 3a, 4a, 5a and 6a show a schematic side view, while the following FIGS. 2b, ... 2e, 3b, 6b each show corresponding views on accordingly designed side panels.
- FIG. 2a shows the tube plate 15 of a collecting tube 11 of a cooler 10 and a cooling tube 12 held in the tubesheet, wherein the cooling tube 12 is the uppermost cooling tube.
- the corrugated fins 13 are arranged.
- a weakening region 49 is formed by the fact that the Side of the corrugated fins 13 held side plate 40 does not extend up to the tube sheet 15, but a portion 49 is formed, in which no side plate is provided. In this case, the region 49 extends over several periods of waves of the corrugated fins 13.
- FIG. 2b shows a plan view of the embodiment of FIG. 2a.
- the see ⁇ plate 40 extends only to a region 49 which extends between the side plate 40 and the tube plate 15 of the manifold 11.
- a plurality of ridgelines 14 of the corrugated fins 13, which are not covered by the side panel 40, can be seen in the plan view in the area 49.
- the side plate is connected in each case exclusively by soldering to adjoining ridgelines 14 of the shaft ribs 13, just as the corrugated ribs 13 are connected to the cooling tube 12 underneath by soldering in the lower ridgelines 14 ,
- the embodiments according to FIGS. 2c to 2e show corresponding configurations which differ only in the design of the side plate 40 from the embodiment according to FIGS. 2a and 2b.
- the side plate according to the figures 2c to 2e each designed so that it extends almost to the tube plate 15 and thus to the manifold 11 and a total of at most a small number, spielnem one or two ridge lines 14 of the corrugated fins not with the side plate 40 communicate. All three embodiments have in common that in the region 49 a tapering of the side plate takes place in its width b.
- FIG. 2c tapers to an acute angle, wherein the tip is formed in the middle of the width B of the cooler 10, wherein in FIG. 2d the tip of the side plate 40 lies in the region of a side edge 42, so that the Side edge 42 at least on one side of the radiator at least to almost to the tube sheet 15 er ⁇ extends over the entire length of the radiator away.
- FIG. 2e shows an embodiment wherein the width b of the side plate is continuously tapered on both sides, the closer the weakening region 49 is to the tubesheet 15. There is almost a transition to a finger-shaped portion of the side plate 40 instead. Due to the rejuvenation gene of the side plate 40, the transmission of forces on the corrugated fins 13 is distributed over a larger area in this area. As a result of the corrugated fins 13 in the tapering region, the force introduction takes place in a larger region of the cooling tube 12, so that no peak loads occur locally which can result in stress regions in the root region of the cooling tube 12 at the tube bottom 15.
- FIGS. 3 a and 3 b as well as FIGS. 4 a and 4 b also show an embodiment of a side panel according to the invention with a weakening area in the vicinity of the collecting tube 11 in a schematically sectioned side view or top view.

- the side part 40 is in each case connected to the corrugated ribs 13, wherein the side part 40 is only slightly close to the tube plate 15 and is spaced therefrom by a narrow gap 47.
- a stiffener 44 is formed in a weakened region 49 of the side panel 40, which extends in the longitudinal direction of the side panel 40 but is raised in the vertical direction over the remaining course of the side panel 40 is.
- FIGS. 3 a and 3 b show an exemplary embodiment wherein, adjacent to the weakened region 49, the side panel 40 has a deflection 45 which has a comb line 46 extending in the direction of the width b of the side panel.
- This deflection 45 ensures a high flexibility of the weakening region 49, which is given in particular by bending the side plate in the region of the deflection 45 and a high extensibility in the longitudinal direction of the side plate 40.
- the embodiment according to FIGS. 4 a and 4 b shows - like FIG. 1 - a design in which the weakened region 49 is formed by fingers 43, wherein the stiffeners 44 extend over the fingers into the unattenuated region of the side panel 40.
- the fingers 43 are thus protected against bending in the vertical direction, namely the vertical direction by the stiffeners 44. Only because the side plate 40 does not extend over the entire width B of the cooler in the region of the fingers 43 ensures that there is no excessive stiffening in the foot region of the cooling tubes 12 on the tubesheet 15.
- FIGS. 5a and 5b show an embodiment in which recesses 48 in the material of the side panel 40 are provided as a weakening.
- a deflection 45 is formed in the transition region between the weakening region 49 and the remaining portion of the side panel 40, wherein in the region of the deflection 45 and a weakening of the side plate 40 is given by the fact that in this area the side plate 40 is not over the full width B of the radiator 10 extends.
- the recesses 48 are formed, in particular, as punched-out sections in the material of the side plate 40, so that a largely closed contour of the side plate is provided.
