Definitions

  • the invention relates to ade endlesskeitkühler for motor vehicles with a brazed cooling system of flat tubes and ribs, made of very thin aluminum sheets, and arranged at the ends of the flat tubes Sammet - or deflection boxes for flowing in the flat tubes coolant, by means of cooling air flowing through the Ribs flows, is cooled.
  • the cooling liquid cooler described in the introduction represents the standard which has been valid for years in such heat exchangers. With the invention described below, this standard is not to be fundamentally changed, but rather optimized in various respects.
  • Compact heat exchangers made of flat tubes and Venetian blind slats are known from the prior art for cooling the drive train of vehicles with internal combustion engines. These are able to achieve the highest cooling performance in the smallest space. In addition to a high volume-related power density but also the lowest possible pressure loss on the coolant side and a low weight are the goal of optimization. At the same time, for reasons of strength, in particular due to thermomechanical loads and by the loads of the cooling network by pressure from the cooling system of the vehicle, the minimum wall thicknesses, especially the flat tubes must be chosen so that the other destinations, such. As the weight reduction and the smallest possible cross-sectional constrictions on the coolant side and the cooling air side (compactness) with low pressure drop, not significantly counteract.
  • the flat tubes often have no or only 1 to 2 inner supports.
  • the pipe heights are in the range of 1.3 mm to 2.0 mm.
  • wall thicknesses greater than 0.20 mm are currently used.
  • the hydraulic diameter (4 x flow area / wetted circumference) is a characteristic variable for the hydraulic behavior. With the mentioned parameters of the pipes without internal use, hydraulic diameters of 1.3 mm to 3.0 mm typically arise on the coolant side.
  • Adeckentechnikkühler which has all but one feature all other features of the preamble of claim 1 is known from US 4,332,293 known.
  • the flat tubes are made of brass and the ribs of copper. Thisdeckenkeitkühler is therefore too heavy and too expensive.
  • the US 5,329,988 is known.
  • Another cooling liquid cooler is off US 4,693,307 known. In it, a solution is presented, which limits the cooling air-side pressure loss by special design of the ribs.
  • the object of the invention is to provide a cost-effectivechenkeitskühlers for motor vehicles whose properties such as in particular high heat transfer performance at comparatively low weight future needs of users should be able to cope in several ways.
  • Each flat tube consists of at least two formed sheet metal strips, wherein at least one of the sheet metal strips forms the wall of the flat tube and another sheet metal strip forms a corrugated, inner channels forming channels therein.
  • the ratio of the constriction factor on the coolant side to the constriction factor on the cooling air side is approximately in the range between 0.20 to 0.44.
  • the hydraulic diameter on the coolant side is approximately in the range between 0.8 to 1.5 mm.
  • each flat tube consists of three formed sheet metal strips, wherein two metal strips form the wall of the flat tube and the third sheet metal strip represents the corrugated, channels forming inner insert in the same.
  • the wall thickness of the flat tube is in the range of 0.10-0.20 mm.
  • the thickness of the inner insert is in the range of 0.03 - 0.10 mm. Because the inner liner can be made from thinner sheet metal, the possibility of weight reduction is extended without neglecting the strength.
  • the constriction factor On the coolant side, the constriction factor is in a range between 0.15 and 0.28. On the cooling air side, however, the constriction factor is in a range between 0.63 and 0.76.
  • the constriction factor is calculated as the ratio of the area through which flows through to the entire end face F of the respective media side.
  • A is the area flowed through.
  • U is the wetted circumference of the area through which it flows.
  • the Fig. 1 shows a view of a cooling liquid cooler according to the invention.
  • the Fig. 2 shows a cross section through a flat tube of the cooling liquid cooler according to the invention.
  • the 3 and 4 show sections of the cooling network of the inventiondeckenkeitskühlers.
  • Fig. 5 - 11 show diagrams showing the difference between the flat tubes of the inventiondeckenkeitskühlers and flat tubes of conventionaldeckenkeitskühlern in several respects.
  • the Fig. 12 shows another flat tube of another cooling liquid cooler according to the invention.
  • Fig. 5 presents evaluations of extensive FEM investigations carried out by the inventors
  • Fig. 5 illustrates that the flat tubes 101 of the inventiondeinstallkeitskühlers because of its inner insert c, the is made of a metal strip which is about 0.03 - 0.10 mm thick is much lighter (ordinate) than conventional flat tubes ordeckenkeitkühler. At the same time, they can withstand higher internal pressures (abscissa). With regard to the internal pressure stability, the overlapping of the metal strips a, b, in the narrow sides S of the flat tubes 101 proves to be, which will be discussed in more detail below.
  • the 6 and 7 represent the evaluation of extensive thermo-hydraulic calculations.
  • the Fig. 6 makes it clear that cooling liquid cooler according to the invention with such flat tubes 101, at approximately identical pressure loss have a significantly higher specific cooling capacity than the prior art.
  • the upper cloud results represents thedefactkeitkühler invention, including the prior art.
  • the Fig. 7 allows for an identical statement, in contrast to Fig. 6 in the Fig. 7 on the abscissa the pressure loss in the cooling air was considered.
  • the cooling capacity is related to the inlet temperature difference ETD and to the mass of the cooling network.
  • the operating point was a coolant flow of 160kg / (m 2 s) and a cooling air flow of 8.0 kg / (m 2 s).
  • the investigated cooling grid dimensions were 600 mm flat tube length, 445 mm net width and 32 mm net depth.
  • Fig. 8 is the hydraulic diameter on the coolant side, ie the flat tubes 1, on the abscissa, the constriction factor on the coolant side, on the ordinate, faced.
  • coolant was given, which means the cooling liquid in this case.
  • the left cloud with results shows the invention and the right-hand cloud of results represents examinations from the prior art. It can be concluded from the illustration that the hydraulic diameters in the flat tubes 101 of the inventive coolant radiator are generally smaller than in conventional coolant radiators.
  • thermo-hydraulic optimization calculation that in the shown flat tubes 101 with internal insert c with hydraulic diameters in the range between 0.8 mm and 1.5 mm and with a restriction factor on the coolant side in the range of 0.15, 0.28 can achieve the highest weight-specific and also volume-specific cooling performance with simultaneously low coolant-side pressure loss.
  • the advantageous limits were entered by dashed lines.
  • the Fig. 11 is intended to show that flat tubes 11 whose inner inserts c have a pitch T ( Fig. 2 ) between 1, 2 and 3, 5 mm, have occurred particularly frequently at a tube height h in the range between 1.1 mm and about 2.0 mm with respect to the advantageous properties described above.
  • the Fig. 1 shows a front view of the cooling liquid cooler according to the invention.
  • This area F is the end face which is used to determine the constriction factor on the cooling air side.
  • the counter is then the sum of the areas which are traversed by the cooling air, which are directed to the cooling air surfaces of all ribs 102, in other words, the end face F minus the areas occupied by the narrow sides of all flat tubes 101 of the cooling network.
  • the flat tube Fig. 2 was one of the flat tubes 1 of the cooling liquid cooler shown in cross section.
  • the flat tube Fig. 2 is made of three endless metal strips. Two rolled with arcuate edges wall parts are identical, but arranged "reversed", wherein the one edge of one part surrounds one edge of the other part and the other edge of one part is encompassed by the other edge of the other part.
  • the inner insert is inserted between the two wall parts.
  • the 3 and 4 show a section of the cooling network 1, consisting of flat tubes 101 and ribs 102.
  • the ribs 102 are so-called blind ribs 102, which have cuts in the rib edges.
  • the cuts are in 3 and 4 indicated by the numerous parallel line.
  • the rib height H was set between 3 and 8 mm, whereby for inserts in the car range 3 - 5.2 mm are cheaper. For commercial vehicles, for example, rib heights of up to 8 mm can be used.
  • the area F was indicated by a dashed line, which is used to determine the refrigerant flow constriction factor. This surface F corresponds approximately to the area which is encompassed by the collecting box 3 on the outside.
  • the sum of the areas occupied by the flat tube sections is set in relation to the area F and gives the constriction factor on the coolant side.
  • the Fig. 12 shows another flat tube of the cooling liquid cooler according to the invention, which is made of only two metal strips a, c.
  • the figure also shows some manufacturing steps and at the bottom of the finished flat tube 101.
  • the one endless metal strip a which is the wall of the flat tube.
  • a fold is incorporated.
  • a bend B is performed leading to the one narrow side S.
  • This metal strip a has a thickness of 0.12 mm.
  • the inner strip c forming sheet metal strip c is about 0.09 mm thick. It is wavy and created with its one longitudinal edge in the aforementioned bend B inside.
  • the flat tube is closed, wherein the second narrow side S is formed by nesting the formed longitudinal edges of a sheet metal strip a. All flat tubes have the advantage that their narrow sides S are very stable despite the low sheet thickness, as the two Figures 2 and 12 demonstrate.
