Definitions

  • the invention relates to a heat exchanger, in particular for a motor vehicle, for heat transfer between a liquid and a gas, with the features of the preamble of claim 1.
  • Such a heat exchanger is known for example from DE-OS 14 51 216 known and has a plurality of tubes which are parallel to each other and spaced are arranged from each other.
  • the tubes are inside in the tube longitudinal direction permeable by the liquid and outside transversely to the tube longitudinal direction flowed around by the gas.
  • Between the tubes are in the gas flow path each arranged a plurality of ribs, the heat-transmitting connected to the pipes.
  • These ribs extend with their Longitudinal direction transverse to the tube longitudinal direction and serve as Spacer for the pipes.
  • all between two adjacent ribs arranged ribs combined into a ribbed band.
  • Each rib has several gills, one behind the other in the rib longitudinal direction and are arranged parallel to each other. These gills extend with its longitudinal direction approximately transversely to the tube longitudinal direction and across the Fin longitudinal direction. Furthermore, the gills are transverse to the gill longitudinal direction inclined relative to the rib longitudinal direction and can thereby at a gas admission of the heat exchanger, the gas flow of one rib side to the other rib side lead. These gills initially cause a constant rebuilding of thermal boundary layers, which are relatively thin on average due to the short start-up lengths and thereby a relatively good heat transfer between the gas and the Allow gills.
  • the gills of each rib are in one first rib longitudinal section inclined in the same direction to each other, while the Gills in a second rib longitudinal section in the same direction to each other and are inclined in opposite directions to the gills of the first rib longitudinal section. Furthermore, all are arranged side by side in the tube longitudinal direction Ribs arranged side by side in the tube longitudinal direction Gills inclined in the same direction. This construction results for the gas with the flow through the heat exchanger, a double deflection transverse to the tube longitudinal direction.
  • the tubes are each provided with a container for Collecting and / or distributing and / or diverting the liquid connected.
  • the deflection of the gas flow through the Gill inclination impeded.
  • the heat transfer performance of Ribs starting from a soldered to the respective tube foot up towards the middle of the rib, resulting in a corresponding on the gas side Temperature gradient forms.
  • the middle portion of the gas flow increases in heat transfer in only a small part.
  • To improve the rib efficiency is it possible to measure the distances between adjacent pipes and thus reducing the gill length or increasing the rib thickness. However, these measures increase the weight and the costs as well as the gas-side flow resistance of the heat exchanger.
  • the present invention deals with the problem, for a Heat exchanger of the type mentioned an improved embodiment specify, in particular, a relatively high heat transfer performance achieved at a relatively small pressure loss.
  • the invention is based on the general idea of designing the gills in such a way that that the inclination of the gill transverse direction relative to the Rib longitudinal direction along the longitudinal gill direction in adjacent Gill longitudinal sections reversed.
  • the gills thereby show respect their longitudinal direction a propeller-like distortion. That means each one Gill in the one gill longitudinal section the gas flow from the first Rib side leads to the second rib side and in the other gill longitudinal section from the second rib side to the first rib side. at a corresponding arrangement and distribution of these gill longitudinal sections may be the cross-flow components of the gas flow be enlarged, thereby increasing the heat transfer between gas and Gill or rib increased.
  • all gills a rib be arranged so that the one another in the rib longitudinal direction following gill longitudinal sections are inclined in the same direction.
  • the trained thereby Rib groups thus have alternating tilt directions or twisting directions in their gills, which is a low pressure loss System generate counter-rotating vortices.
  • This vortex system leads on the one hand to a gas exchange in the tube longitudinal direction and on the other hand in Fin longitudinal direction. This results in an improved turbulence the gas flow in the middle of the ribs. Overall, can thereby increasing the heat transfer between gas flow and ribs become.
  • the number of ribs in the rib groups be chosen so that the rib groups in the tube longitudinal direction extend as far as adjacent tubes transversely to the tube longitudinal direction spaced apart from each other. Due to this design can at the Flow through the heat exchanger essentially cylindrical vortex generated at relatively low pressure losses a particularly ensure favorable heat transfer.

  • the tubes 2 are in their interior in their by a double arrow symbolized pipe longitudinal direction 5 can be traversed by a liquid.
  • the containers 3 and 4 serve for collecting and / or distributing and / or Redirecting the fluid flow.
  • the heat exchanger 1 around the heat exchanger 1 of a motor vehicle.
  • the heat exchanger 1 is a so-called “Flat tube heat exchanger", in which the tubes 2 as flat tubes are trained; that is, the tubes 2 are transverse to their longitudinal direction 5 are significantly larger in the rib longitudinal direction 8 than in the rib transverse direction 9.
  • the flat tubes can also be soldered against each other Slices are built, it being on the inner structure of the slices or pipes 2 does not arrive here.
  • the tubes 2 are spaced from each other, they are transverse to the outside Tube longitudinal direction 5 and substantially perpendicular to the heat exchanger plane, ie perpendicular to the plane of the drawing, from a gas, e.g. Air, flow around.
