Definitions

  • the present invention relates to an exhaust gas cooler for a motor vehicle powered by an internal combustion engine, comprising an exhaust gas inlet, an exhaust gas outlet and a plurality of channels through which exhaust gas flows extend between the exhaust gas inlet and the exhaust gas outlet and can be flowed around by cooling air.
  • the exhaust gas cooler at least one Has cooling air baffle through which the pass through exhaust gas-flowing channels, the Cooling air baffle (s) obliquely to the longitudinal direction of the Exhaust-flow channels is / are arranged.
  • the exhaust gas cooler at least one Has cooling air baffle through which the pass through exhaust gas-flowing channels, the Cooling air baffle (s) obliquely to the longitudinal direction of the Exhaust-flow channels is / are arranged.
  • the exhaust gas cooler at least one Has cooling air baffle through which the pass through exhaust gas-flowing channels, the Cooling air baffle (s) obliquely to the longitudinal direction of the Exhaust-flow channels is / are arranged.
  • the cooling air guide plates in a blade-like manner in at least one of its edge regions are bent. This contributes to a further improvement Actuation of the channels through which the exhaust gas flows Cooling air at. This applies in particular if the Cooling air baffles in the area of their leading edges are curved like a scoop for the cooling air.
  • the exhaust gas cooler To manufacture the exhaust gas cooler according to the present In principle, various inventions are suitable Method. So it is basically possible that from the exhaust gas flow channels and the cooling air baffle plates formed cooling area from a plurality of prefabricated, Breakthroughs for the exhaust gas Channels having cooling air baffles on the one hand and a plurality of channels through which exhaust gas flows assemble, in particular the exhaust gas Channels through the corresponding breakthroughs the cooling air guide plates passed and the Components then firmly connected can be.
  • the present invention stands out characterized in that the cooling air guide plates from a A plurality of cooling air baffle segments are joined together are, in turn, in one piece with an exhaust gas flow channel or a bundle of channels through which exhaust gas is produced.
  • Cooling air baffle segments are particularly suitable the procedure below: First, be using the deep-drawing technique from flat Flat material made of profiled sheets, each a half-shell of the channel through which the exhaust gas flows or Bundle of exhaust gas flow channels with at least a half of a Form the cooling air baffle segment.
  • the deep-drawn sheet metal on the one hand at least one over trough-like extending the entire length of the sheet Depression, preferably a plurality of parallel, extending over the entire length of the sheet trough-like depressions after joining two mirrored profiled sheets flowed between them Channel / channels defined / define, as well as further at least one at an angle to - by the extension of the trough-like recess (s) defined - Longitudinal bead or rib that the allocated half of the at least one Cooling air baffle segment of the concerned exhaust duct or bundle of exhaust gas Channels forms on.
  • the exhaust gas cooler As for the installation of the exhaust gas cooler according to the invention in a motor vehicle powered by an internal combustion engine is particularly preferred in the direction of travel the exhaust gas cooler an air guide component arranged, the Air leads into the work area of the exhaust gas cooler.
  • an air guide component it can in particular is a NACA nozzle. This in turn carries to improve the inflow of cooling air the channels through which the exhaust gas flows
  • the exhaust gas cooler according to the invention particularly preferably arranged in an exhaust main line, wherein an exhaust gas bypass line bypassing the exhaust gas cooler can be provided. That way bypassed the exhaust gas cooler in such operating conditions in which exhaust gas cooling is to be avoided, for example in the warm-up phase.
  • an adjustable or convertible Flow throttle can be provided to control the Distribution of the exhaust gas flow to the exhaust gas cooler on the one hand and the bypass line on the other hand either in the bypass line or in the Main line.
  • an adjustable or convertible Flow throttle can be provided to control the Distribution of the exhaust gas flow to the exhaust gas cooler on the one hand and the bypass line on the other hand either in the bypass line or in the Main line.
  • an adjustable or convertible Flow throttle can be provided.
  • Additive or alternatively, to the function of the Exhaust gas cooler to influence the supply of cooling air to the exhaust gas cooler by means of an adjustable Flow restrictor can be changed.
  • the drawing shows a perspective view of a cooling segment of an exhaust gas cooler according to the present invention.
  • Cooling section of an exhaust gas cooler comprises six exhaust gas-carrying Channels 1, in the form of two bundles of three exhaust channels. Every bundle of exhaust gas-carrying The channel is formed by two profiled sheets 2, 3.
  • the two sheets 2 and 3 are mirror images profiled to each other in such a way that they mutually between two adjacent exhaust gas flows Touch channels 1 in a line.
  • the two sheets 2 and 3 each in a manner known as such (e.g. by means of Spot welding). in the rest of the two profiled sheets 2, 3 are longitudinal their common longitudinal edges 8 gas-tight with each other welded.
  • Cooling air baffle segments 5 Two adjacent bundles of exhaust gas channels are each connected by connecting each other opposite, arranged in the same plane Cooling air baffle segments 5 by means of the front arranged welds 11 connected to each other.
  • the concept of "Cooling air baffles" do not necessarily require that the individual cooling air baffle segments with each other are firmly connected. Rather, between these there are also air gaps. However, it is Connection of the cooling air baffle segments to one another a cheap way, the bundles of exhaust gas Connect channels.
  • Each of the cooling air baffles faces in the entry area a shovel-shaped curved entry plate 6.
  • the Size of the entrance panels 6 increases in the direction of travel Motor vehicle seen from the front to the rear, so that with an exhaust gas cooler installed parallel to the underbody the individual baffles 6 in the direction of travel considered increasingly sticking out to this way an optimal cooling air supply in the individual cooling segments and thus over the entire Exhaust gas cooler to cause.
