Definitions

  • the present invention relates to a side plate for radiator, in particular for tube cooler, as used for example in vehicles with internal combustion engines.
  • Such coolers have a radiator body in which tubes extend in the longitudinal direction, heat exchange surfaces being formed between the tubes.
  • the cooler of at least one pair, located on both sides of the radiator body side plates is included.
  • the side plates extend longitudinally or transversely to the direction of extension of the tubes of the tube cooler.
  • they limit the heat exchange surfaces serve e.g. Mounting purposes and prevent, for example, the penetration of undesirable contaminants in the area between the heat exchange surfaces and thus a deterioration of the heat exchange performance of the heat exchanger.
  • the US 2002/029869 A1 discloses a side panel having the features of the preamble of claim 1, wherein an upstanding angled portion breaks at a relatively low tension.
  • the object of the invention is to provide a side plate which is designed such that the emergence of stresses due to different thermal expansion of side plate and tube cooler is avoided.
  • Such a side plate as may be used in particular for tube cooler, is intended to be used in radiator bodies in which tubes extend in the longitudinal direction and heat exchange surfaces are arranged between the tubes, wherein the side plates are intended to the radiator on at least one Complete pair of opposite sides.
  • the side plates are characterized in that they have a weakening region, in which region the material of the side plate is weakened such that a thermal expansion compensation is made possible in accordance with that of the heat sink.
  • This material weakening makes it possible to adapt the thermal expansion of the side panel to that of the heat sink and thus to allow a fixed mounting of the side panel on both sides of the radiator body. At the same time the occurrence of stresses in both the side plate and in the radiator body due to different thermal expansion is avoided.
  • the weakening of the weakened area is formed by openings in the material of the side plate.
  • the breakthroughs are designed so that a network of webs forms. By this measure it is achieved that a high mechanical flexibility of the side part is given, which can compensate for a different thermal expansion of the radiator body thermal expansion. It is particularly favorable if the apertures are designed in such a way that the web of webs forms diamonds standing on the tip in the longitudinal extent of the side plate, that is to say in the longitudinal direction.
  • the webs bounding the apertures each extend with a directional component in the longitudinal direction of the side plate, in which the different thermal expansion acts, and always in a directional component transversely thereto, so that nevertheless a certain rigidity and dimensional stability of the side plate remains ensured.
  • the honeycomb-shaped openings can be formed both by a hexagonal and by an octagonal shape of the openings.
  • Hexagonal honeycomb breakthroughs have the advantage that they can form a closed surface, while in octagonal honeycombs repeatedly arise diamond-shaped intermediate surfaces and thus no uniform continuous pattern.
  • octagonal honeycombs form again and again in the longitudinal direction and in the transverse direction of the side plate extending material areas, while hexagonal honeycombs have only either in the longitudinal direction or in the transverse direction of the side plate extending material webs. It may thus result in a different longitudinal stiffness in relation to the transverse stiffness of the side plate.
  • a weakened region is formed from a plurality of rows of apertures, wherein the rows of apertures are preferably offset from each other and the number of rows can be selected so that seen in the direction of extension of the side plate, the length of the apertures summed at each point transverse to Extending direction is at least 1.5 times, preferably at least two to three times the maximum length of an opening in the direction of extent. This measure ensures that over the entire width of the side plate away in the longitudinal direction seen a certain distance material is free, so that over the entire width of a certain defined minimum attenuation of the longitudinal stiffness of the side plate is achieved.
  • this is bent at least in the weakened area in cross-section, preferably formed U-shaped.
  • Such a cross-sectional design also in the region of the weakened area increases the connection stiffness of the side plate and guarantees dimensional stability.
  • FIG. 1 shows a radiator 10, wherein extending in the longitudinal direction of the radiator tubes, which are surrounded by heat exchange surfaces 11.
  • Two opposite sides of the radiator are bounded by side plates 12, which are fixedly held on other parts connected to the radiator and are also aligned in the longitudinal direction.
  • FIG. 2 shows an oblique view of such a side plate 12 with two weakening regions 13, wherein the weakening regions 13 are each formed by openings 14 in the material of the side plate.
  • FIG. 3 shows an enlarged view of such a weakening region 13.
  • the openings are formed side by side, that there is a network of webs 15 therebetween.
  • the webs 15 are formed so that they each limit diamond-shaped openings.
  • the openings 14 are arranged in several rows 16. In the illustrated embodiment, four rows of apertures 14 are formed one behind the other, forming the weakened region 13. The rows are offset from each other so that over the entire width of the side plate 12 away a material-free route is given, the total length is greater than twice the maximum length of an opening in the direction of extension.
  • the diamond-shaped form of the openings ensures that a compact, surface-covering arrangement of the openings can be realized.
  • a constant width of the webs 15 between two openings remains maintained throughout, so that the stiffness of the side plate in the region of the breakthrough is well determined.
  • the side plate 12 is formed in a U-shaped cross section, wherein the cross-sectional shape is maintained even in the weakening region 13. This ensures that a corresponding material weakening is also given in this edge region, at the same time a basic measure of torsional rigidity and dimensional stability of the side plate is ensured even in the weakened region 13.
