Definitions

  • the invention relates to a protective device against impinging particles for a radiator in a motor vehicle according to the preamble of claim 1.
  • Radiators in motor vehicles generally consist of a plurality of cooling tubes, which are arranged in parallel at intervals as web tubes and which are connected to one another by selected heat dissipation plates. Round tubes or flat tubes are used as media-carrying cooling tubes. Such coolers are used, for example, as heat exchangers in the engine cooling circuit or as condensers in an air conditioning system in the vehicle.
  • coolers are usually arranged in the front area of the vehicle at a location that can be easily flowed through by the wind.
  • a cooling air flow can particles such. B. small gravel, with it, especially when overtaking, oncoming traffic and convoys on roads with insufficiently paved ground.
  • the cooling tube walls are dimensioned as thin as possible, so that the coolant-carrying web tubes can be mechanically damaged by such particles. Less critical damage to the surface coating can occur, but the thin-walled standpipes can also be leaked. This leads to a failure of the engine cooling system and the vehicle stopping in connection with costly repairs.
  • Known generic protective devices for a motor vehicle radiator against impinging particles consist of differently designed protective grids which are arranged at a distance from a radiator.
  • simple protective grilles as a grille
  • special protective grille designs are known.
  • a fine-mesh, flat wire mesh in an interchangeable frame in front of a vehicle cooler is known (DE 36 29 880 A1), with which contaminants in particular are to be kept away from the radiator fins.
  • a fine-mesh wire mesh however, clogs itself up with impurities and then disadvantageously hinders the air throughput through the cooler and considerably reduces the cooling capacity.
  • radiators in particular for insects, consists of a grid-like arrangement of vertical, parallel metal strips which are attached at an angle of 45 ° with respect to the longitudinal direction of the vehicle. This means that impinging particles should no longer hit the radiator block directly, but should be deflected according to the angle of attack of the metal strips. However, the cooling air flow is deflected and reduced accordingly. This arrangement is therefore also complex and leads to a reduction in the cooling capacity.
  • a spiral wound from a flat metal strip is used (DE-OS 1 755 802).
  • an embodiment of a radiator grille from a flexible band is known (DE 44 25 196 A1), which can be wound up and unwound automatically and cleaned in the process. This represents a very complex design, which is particularly ineligible for passenger cars for reasons of cost.
  • radiator grilles have the common disadvantage that they are intended to protect the radiator surface, which is at risk from a particle impact, overall and globally. This requires a small mesh size for good protection, however, which leads to an unfavorable reduction in the cooling air flow.
  • protective grids arranged separately at a distance from a radiator are complex to manufacture, require space and weight due to their required stability and brackets.
  • Protective grids are also known at air inlet openings of housings and encapsulations, in particular engine compartment encapsulations (DE 37 03 716 A1; DE 40 15 304 A1), the cross-sections of which contain cross-sectional profile shapes with undercuts and / or combinations of different materials in order to allow particles and Reduce foreign bodies.
  • a spatial assignment to a vehicle radiator is not available here.
  • the object of the invention is to provide a protective device against impinging particles for a radiator in a motor vehicle, which does not or only slightly influences the cooling air flow with a good protective function and is simple and inexpensive to produce in a space-saving and weight-saving arrangement.
  • the previous principle of global protection of the entire radiator surface loaded by impinging particles is abandoned.
  • This is based on the knowledge that the areas between the web tubes in any case represent throughflow openings and the end edges of heat dissipation plates oriented in the direction of flow, which point here in the direction of flow, are relatively insensitive to impinging particles.
  • even more severe damage in the intermediate areas of web tubes cannot lead to a malfunction of the cooler, since cooling medium only flows in the web tubes.
  • the web tubes, which are sensitive to damage are provided with armor directly and without spacing directly in vulnerable areas, which ensures mechanical protection against impinging particles.
  • this armor directly touches the endangered tube walls is assigned and for a good protective function only has to have the same or only a slightly larger width than the endangered web tube areas, the cooling air throughput is advantageously not or only slightly reduced by the protective device.
  • a protective device is simple and inexpensive to manufacture and can be installed in a small space.
  • such armor is to be attached directly to the bridge tube walls and therefore does not require any additional, separate, separate brackets from the cooler.
  • the armor consists of a thickening of the material of the endangered tube walls compared to other tube walls.
  • Previous manufacturing processes for web tubes, in particular continuous casting processes, can continue to be used, as can previous assembly processes. Due to the material thickening that is only used in a targeted manner at the endangered tube wall areas, the weight of the cooler is increased only slightly and is less than the weight of an arrangement consisting of a weight-optimized, thin-walled cooler with a separate protective grille device.
  • the thickening of the material provides effective protection against denting and leakage due to impacting particles and also increases the stability of the standpipes and thus the entire cooler.
  • An alternative embodiment of armor which can optionally be used in addition to the material thickening described above, consists of a caterpillar of elastic material applied to the web tube walls which are at risk of particle flight. This application is advantageously carried out automatically in the manufacture of the web tubes. Silicone, polyurethane or other similar materials can be used as the elastic material. An applied caterpillar can also protrude somewhat over an area at risk of impact, so that this area is not only covered but somewhat overlapped for very secure particle impact protection. With this measure, the cooler flow is influenced only slightly.
  • a thickening of material on only one side of a web tube may be difficult to recognize when installing a cooler.
  • the armor consists of covering tube rails arranged on and covered by the particle tube walls which are loaded and endangered by particle flight.
  • These cover rails are expediently connected to form a lattice part, the cover rails being arranged in the lattice network at a distance from the web tube walls to be covered.
  • the cover rails or the grid part can be clipped directly onto the web tubes or clipped into the spaces between them.
  • the required clips can be molded directly onto the cover rails or the grid part or can be designed as separate clip pieces.
  • the cover rails, or the lattice part and the clips can be made from sheet metal or preferably from plastic as plastic injection molded parts.
  • the cover rails used here can also have a somewhat larger width than the web tube wall areas to be covered. Since the tube wall areas to be covered have only a small expansion, in particular in the case of flat tubes, in comparison to the entire cooler surface, an increase in the width of the cover rails by 20% to 30% compared to the width of the vulnerable tube walls only has an insignificant influence on the cooling air throughput.
  • the web tubes as flat tubes have an elongated, narrow and rectangular cross section, each with two opposite narrow sides and broad sides.
  • cooling medium-carrying longitudinal chambers are formed by several parallel webs lying between the broad sides.
  • the narrow sides of the web tubes are the areas at risk of impact due to particle flight and are formed by the outer webs that support the armor.
  • the armoring of these lateral outer webs consists, according to the above statements, of a material thickening and / or an applied bead of elastic material and / or of a direct covering by a cover rail or by a corresponding grid part.
  • the outlay for the protective device according to the invention can advantageously be reduced, if necessary, in that only heavily endangered cooler areas or web tube areas are covered by armor according to the invention.

Abstract

Ce dispositif protège le radiateur (1) d'un véhicule à moteur contre l'impact de particules. Le radiateur (1) comprend des tuyaux à nervures (2 à 6) mutuellement espacés, servant à l'écoulement du milieu de refroidissement. Selon l'invention, les parois des tuyaux à nervures, qui à l'état monté du radiateur (1) sont orientées dans la direction de l'impact des particules (flèche 19) et soumises à des contraintes mécaniques, présentent, comme seule protection contre l'impact des particules, un blindage qui les recouvre directement et y est mécaniquement relié sans aucun écartement. Ce blindage est de préférence obtenu par un simple épaississement (18) du matériau dont sont constitués les tuyaux à nervures, par application d'une chenille (21) en un matériau élastique sur les tuyaux à nervures et/ou par des barres (23) accrochées par des clips sur les tuyaux à nervures, plusieurs rails de couverture (23) formant de manière appropriée une grille (22) sur les tuyaux à nervures.
