Definitions

  • the invention relates to a cooling device, in particular exhaust gas cooling device, for an internal combustion engine with an outer shell, in which at least one heat transfer unit is arranged, which has a coolant inlet and a coolant outlet and which has an outer housing such that a formed between the outer shell and the heat transfer unit, from A jacket through which a coolant flows is separated from a channel which is formed in the heat transfer unit and through which the fluid to be cooled flows.
  • Such cooling devices are used, for example, in internal combustion engines as exhaust gas cooling devices for reducing pollutant emissions, in which the exhaust gas is cooled, mixed with the freshly drawn air and fed to the cylinders. This temperature reduction of the cylinder filling reduces pollutant emissions.
  • Such a cooling device is for example from the DE 10 2005 045 103 B3 known.
  • This cooling device is supplied with coolant via a coolant inlet, in which case the coolant is distributed over the entire circumference of the heat transfer unit in order to leave the coolant device via the coolant outlet after heat exchange with the medium to be cooled, in this case exhaust gas.
  • At least one guide bar is arranged between the outer shell and the heat transfer unit, wherein the next closest to the coolant inlet guide has two sections, the second section extends angled to the first section, such that the first section is parallel to the natural flow and the second subsection has an orientation that is substantially away from the flow direction.
  • the second section is angled at an angle a of at least 20 °, preferably at least 30 ° to the first section.
  • the angle enclosed between the first section and the second section on the windward side can be ⁇ > 90 °, particularly preferably> 110 °. In this way, the flow losses can be minimized.
  • the guide ribs or the guide webs may be arranged on the outside of the heat transfer unit in order to ensure the simplest possible production.
  • a cooling device 1 which is used in particular as an exhaust gas cooling device of an internal combustion engine, is shown.
  • the cooling device 1 consists essentially of a cup-shaped outer shell 2, in which a known heat transfer unit 3 is used.
  • the heat transfer unit 3 has both a coolant inlet 4 and a coolant outlet 5.
  • 4, 5 are in the present illustration, only the positions at which the coolant enters the cooling device or emerges from this, so the coolant flows at position 4 in the cup-shaped outer shell 2 and flows around the heat transfer unit 3 shell-shaped, then at position 5 leave the outer shell 2 again.
  • the heat transfer unit 3 is shown only schematically in the present drawing. However, it should be clear that in this heat transfer unit 3, a channel through which exhaust gas flows is formed, and an exhaust gas inlet 6 and an exhaust gas outlet 7 are provided correspondingly.
  • a guide bar 8, 9 is arranged which allow positive guidance of the coolant in a jacket 9 formed between the outside of the heat transfer unit 3 and the outer shell 2.
  • the coolant inlet 4 nearest guide web 8 consists essentially of two sections 10, 11, wherein the first section 10 is parallel to the natural flow of the coolant and the second section 11 has a direction away from the flow direction of the coolant orientation.
  • the natural flow of the coolant is essentially dependent on the arrangement of coolant inlet 4 and coolant outlet 5 relative to one another, the flow angle of the coolant with respect to the coolant inlet 4 and the flow rate of the coolant.
  • a course of characterized flow is schematically represented by flow lines.
  • 5 Leitorgane 12 are provided in the vicinity of thedeffenauslasses, which lead to a uniform, executed toméstoffauslassstoffddling inflow of the coolant. Since these guide members 12 are in the present view on the underside of the heat transfer unit 3, they are also shown only in dashed lines.
