Definitions

  • the invention concerns a radiator for a motor vehicle.
  • the radiator has a block formed from several parallel tubes, through which flows a coolant.
  • a radiator for a motor vehicle having a plurality of individual parallel tubes running between two end plates.
  • the end plates have oblong depressions to receive the individual tube ends.
  • Coolant box parts are secured to the end plates, which cover the tube ends and serve to divert the cool water flowing through the individual tubes.
  • the block depth of the radiator is defined in terms of the width of the individual tubes used in the tube sheet with the cooling fins (ribs) running in between. The block depth in one region of the radiator can be less than that in another region, thanks to tubes of different depth, so that the radiator can be adapted to the circumstances of the chassis.
  • a radiator is also presented in published, French patent application FR 2 771 481 A, whose block depth in one region of the radiator is less than that in another region, so that the radiator can be adapted to the factors of the chassis.
  • radiators having different block depths in order to adapt them to the conditions of the chassis. However, in each segment, only uniform block depths are utilized.
  • radiator In vehicles with different motorization, it is customary today to adapt the cooling performance within a vehicle platform by modification of the radiator, or rather the block depth, to the particular cooling demand.
  • the initial basis is always the largest radiator, i.e., the greatest required block depth.
  • the radiator is then joined to add-on elements at the air intake and outlet sides, being for the most part identical for all variants (e.g., coolant condenser or fan frame).
  • a radiator for a motor vehicle contains a block having several parallel tubes through which flows a coolant and the tubes have at least two different depths. At least two spaced-apart ones of the tubes have a first depth being greater than a second depth of the tubes lying in between.
  • the tubes having the first depth function as support tubes.
  • the inventive radiator contains a block formed from several parallel tubes, through which flows a coolant, while two or more spaced-apart tubes have a depth greater than the depth of the tubes lying in between and are configured as support tubes.
  • the tubes with greater depth bring about a stiffening of the tube sheet, which improves the fatigue strength of the radiator.
  • the first and the last tube have a depth that is greater than the depth of the tubes lying in between, and are configured as support tubes. This configuration gives the radiator improved stability when using not very many tubes.
  • the radiator is provided with support tubes at the ends and in the middle region that have a depth which is greater than the depth of the other tubes. This configuration is used when a greater stability is needed.
  • a number of the support tubes is greater than two and between the support tubes are disposed shorter tubes of the tubes, and a spacing between neighboring the support tubes is regular.
  • cooling fins run between the tubes.
  • the block has a tube sheet and the tubes and the support tubes are disposed centrally in the tube sheet.
  • the tubes and the support tubes are disposed displaced to one side of the block.
  • the block has a tube sheet with a constant depth over an entire height of the block for the support tubes.
  • FIG. 1 is a diagrammatic, perspective view of a radiator according to the prior art
  • FIG. 2A is a diagrammatic, sectional view through the radiator of the prior art
  • FIG. 2B is a diagrammatic, sectional view through another radiator of the prior art
  • FIG. 2C is a diagrammatic, cross-sectional view through a radiator according to a first embodiment of the invention.
  • FIG. 2D is a diagrammatic, cross-sectional view through a radiator according to a second embodiment of the invention.
  • FIG. 1 there is shown a radiator 1 for a motor vehicle according to the prior art.
  • the radiator 1 serves to lower the temperature of the coolant flowing in.
  • a non-illustrated coolant pump pumps the heated coolant through an inlet opening 2 and through a plurality of parallel tubes 3 in the radiator. Between the tubes 3 there are cooling fins or ribs. By thermal conduction, the heat is transported to the outer surfaces of the tubes 3 , where it is surrendered via the cooling fins to the air flowing through the radiator 1 .
  • the tubes 3 with the cooling fins running between them together form one block 4 of the radiator 1 .
  • End plates (or tube sheets) 5 , 6 have oblong passages 7 (see FIG. 2A ), which receive the ends of the individual tubes.
  • Coolant box parts 8 , 9 are attached to the end plates, which cover the tube ends and serve to divert or distribute or collect the coolant flowing through the individual tubes 3 .
  • FIG. 2A shows a schematic cross section through a radiator 1 identical to the radiator 1 shown in FIG. 1 . Only one of the tube sheets 5 is shown. A depth 10 of the tubes 3 is shown by the direction of an arrow. As can be seen from FIG. 2A , the depth 10 of the tubes 3 basically corresponds to the depth of the tube sheet 5 . The depth 10 corresponds to the direction of flow of the air through the radiator 1 .
  • the radiators 1 are built with a definite block depth for different vehicles. It may happen that only short blocks 4 will be used in a large tube sheet 5 , as can be seen in FIG. 2B . It can be seen from FIGS. 2A and 2B that the passages 7 for the individual tubes 3 are larger when using a large block ( FIG. 2A ) than when using a small block ( FIG. 2B ). But the size of the tube sheet 5 is always the same. This necessarily causes fatigue strength problems, since the unequal supporting effect of the block in FIG. 2B on occasion causes warping due to the heating process. It makes no difference whether the tubes 3 are disposed in the middle of the tube sheet 5 or shifted to one side (as in FIG. 2B ).
  • support tubes 15 when using small block dimensions ( FIG. 2B ), two or more tubes from a rather large block are used as supports at the critical sites. These tubes are hereafter called support tubes 15 .
  • FIG. 2C shows a preferred embodiment of the invented radiator 1 .
  • a small block dimension with a large tube sheet 5 is used here.
  • Three tubes 3 are replaced by three larger support tubes 15 .
  • the support tubes 15 are situated at the ends and in the middle region of the block 4 , but a different configuration is possible.
  • the support tubes 15 make it possible to improve the fatigue strength of the radiator 1 , because large stresses can be avoided.
  • FIG. 2D demonstrates another embodiment of the invented radiator 1 .
  • a small block dimension is used with a large tube sheet 5 .
  • Five tubes 3 are replaced by five deeper support tubes 15 .
  • This configuration is particularly suited to radiators 1 with rather long sheet parts 5 , 6 , while a larger number of support tubes 15 is advantageous.
  • the support tubes 15 are distributed preferably uniformly over the radiator block 4 .
  • the number of support tubes 15 depends on the size of the radiator block 4 . Longer radiator blocks 4 require more support tubes 15 than short radiator blocks 4 .
  • the number of support tubes 15 also depends on the ratio between the depth 17 of the tube sheet (or the depth of the support tubes 15 ) and the depth 16 of the smaller block dimension.
  • the depth 16 of the smaller block dimension is very small in comparison to the depth 17 of the tube sheet 5 , this leads to intensified fatigue strength problems.
  • the use of several support tubes 15 is desirable.
  • first two tubes and the last two tubes in the block can be configured as support tubes 15 , which provides increased fatigue strength.
