Definitions

  • the invention relates to a cooler, in particular for Motor vehicles with one of a medium to be cooled flowed through pipe that is to be arranged in a cooling air flow is determined.
  • coolers are often used in motor vehicles, which consist of pipe loops arranged in a cooling air flow consist.
  • These pipe loops can be made from one smooth round tube or to increase the cooling capacity given length consist of finned tube, the finned tube made using a smooth round tube is attached to the radially projecting, thin-walled ribs or are molded to form the tube as an individual Rings or in the form of a spiral.
  • the production such finned tubes and the bending of the finned tubes in is the appropriate loop shape for the respective cooler consuming.
  • the invention has for its object a cooler to create the kind mentioned above, the more cost-effective can be manufactured as one using finned tubes manufactured cooler, which on a pipe length unit related cooling capacity is significantly higher than the cooling capacity smooth pipes of comparable dimensions.
  • this object is achieved in that the Tube of the cooler a variety of upset, annular Has waves extending radially from the pipe wall extend outside and have a distance from each other.
  • the individual waves are preferably designed so that between their radially extending wall sections one related to the interior of the pipe Space is provided.
  • the design of the cooler according to the invention stands out due to low manufacturing costs and good cooling performance.
  • the upset waves cause an increase in surface area of up to 50% compared to a straight pipe.
  • the generated when compressing the waves Inner contour of the tube is swirling through the tube conducted medium achieved, resulting in a better heat transfer and a higher cooling capacity results.
  • the waves on the tube can be arranged in any position. This is a flexible adaptation to the installation conditions for the Cooler easily possible.
  • Corrugated pipe sections can also provide smooth pipe sections be subsequently formed or with holders can be provided.
  • Aluminum tubes can be used for the cooler.
  • the drawing shows a section of a tube 1 cooler according to the invention, partially cut.
  • the pipe 1 has annular shafts 2 at regular intervals, which extend radially outwards and through axial Compression of a previously smooth, cylindrical tube as a semi-finished product have been generated. Between the waves 2 there are smooth cylindrical tube sections 3, the Diameter essentially corresponds to that of the starting semi-finished product.
  • the individual shafts 2 have one another parallel wall sections 4 in the form of circular washers, which are arranged radially to the pipe axis and which on their Edges merge into wall sections 5, 6, which have approximately the shape of partial torus surfaces. Between the wall sections 4 and 6 of each shaft 2 is an annular space 7 provided that in connection with the interior 8 of the tube 1 stands.
  • the shafts 2 have an outer diameter which is approximately that 1.3 to 1.5 times the outside diameter of the pipe sections 3 is.
  • the width of the gap 7 is essentially equal to the wall thickness of the pipe sections 3, but can also be smaller. Especially in the radially outer Area is a smaller width or insufficient specification of the space 7 without disadvantage for the function.
  • the center distance between the individual shafts can be any to get voted. A center distance has proven to be particularly favorable proven to be about the outside diameter of the Pipe sections 3 corresponds.
  • the tube 1 from a liquid medium to be cooled e.g. the oil an internal combustion engine or a motor vehicle transmission flows through and on the outside with a cooling air flow applied.
  • a liquid medium to be cooled e.g. the oil an internal combustion engine or a motor vehicle transmission
  • this is ensured by Formation of waves 2 by up to 50% enlarged surface of tube 1 for one compared to a smooth one Pipe greater heat transfer.
