Definitions

  • the invention relates to a heat exchanger for an internal combustion engine according to the preamble of claim 1.
  • Heat exchangers for cooling recirculated exhaust gas are known from the prior art.
  • exhaust gas cooling involves the problem of the high chemical aggressiveness of the exhaust gas and of the low pH of its condensates.
  • only exhaust gas heat exchangers made of austenitic steels with high corrosion resistance existed so far.
  • Such steels generate high material costs and often further consequential costs due to the more complexerieserie-
  • austenitic steels are usually poor heat conductors, so that heat exchangers of a given cooling capacity relatively large and heavy build.
  • JP 2003 222498 A discloses a shell-and-tube heat exchanger with heat transfer elements made from super-ferritic stainless steel.
  • the publication DE 103 28 846 A discloses a gas cooler with domes made of stainless steel.
  • the regularly better thermal performance of ferritic steels is used to a particular extent compared to austenitic steels in that the ferritic part of the heat exchanger is in contact with the fluid. Due to the higher thermal conductivity of the ferritic steel thus a total of a small-sized, material, weight and cost-saving design of a heat exchanger for exhaust gas cooling is possible.
  • the fluid is particularly preferably a recirculated exhaust gas or exhaust gas / air mixture of the internal combustion engine, the fluid temperature in the first connection region being more than 300 ° C., in particular more than 500 ° C., under normal operation. As a result, the risk of condensation of acidic condensate from the exhaust gas in the region of the entire heat exchanger is reduced.
  • the ferritic part of the heat exchanger essentially corresponds to the first connection region and is adhesively bonded to the exchanger region.
  • the temperatures are particularly high, which is why ferritic steels can be used relatively easily.
  • ferritic steels usually have a lower coefficient of thermal expansion than austenitic steels, which is why the combination of a ferritic connection region with a subsequent austenitic exchange region is particularly favorable in terms of strain-induced material stresses.
  • the first connection region preferably has a widening of a passage cross-section in the direction of the exchanger region.
  • an adjustable flap can be arranged in the connection region. By way of example, a distribution of the exhaust gas to a cooled region or a bypass channel can take place through the flap.
  • the exchanger region has a plurality of exchanger tubes.
  • Tube coolers are mechanically very stable and are particularly suitable in connection with a liquid coolant.
  • the exchanger area expediently has an exchanger housing through which the liquid coolant can flow. Since the exchanger housing is not regularly in contact with the exhaust gas, it is particularly appropriate that the exchanger housing is made of ferritic steel, since even in the event of rust through, no liquid coolant gets into the combustion chambers of the engine.
  • a further part of the heat exchanger consists of a further ferritic steel.
  • ferritic steels with different corrosion resistance and mechanical properties, which is reflected regularly in the material price.
  • the various parts of a heat exchanger may consist of different ferritic steels to optimize costs.
  • the heat exchanger comprises a plurality of disc-like interconnected disc elements.
  • a heat exchanger is particularly suitable as exhaust gas heat exchanger.
  • a Berippungselement is arranged between the disc elements, which consists of the ferritic steel. Due to the type of construction, corrosion of the ribbing elements does not regularly entail the risk of a breakthrough of coolant into the fluid area, which would otherwise lead to engine damage due to water hammer. Therefore, in particular separable applicable Berippungsetti for training of ferritic steel are particularly predestined.
  • Such a ribbing element can be arranged in the fluid to be cooled and / or in the coolant. If a ribbing element in both the fluid is arranged as well as in the coolant, so these Berippungseiemente regularly differ in their training.
  • a housing which surrounds the disk elements and which consists of the ferritic steel is particularly preferably provided.
  • a high-life corrosion of the housing would not lead to a connection between the coolant and the exhaust gas, whereby the risk of engine damage is reduced.
  • Such a housing is a component of considerable size, in which considerable costs can be saved by using ferritic steel.
  • the disc elements when using a sufficiently corrosion-resistant ferritic steel, it is also preferable for the disc elements to be made of ferritic steel, which serves for the heat conduction and thus the total heat exchanger performance for a given size.
  • another part of the heat exchanger is made of an austenitic steel, whereby a material with a high corrosion resistance is used at least at critical points.
  • the austenitic steel is preferably a steel from the group 1.4301 and 1.4404. These material designations comply with the standard DIN EN 100 88-2, to which reference is made for all the numbered material designations mentioned in the context of the present invention.
  • the part made of ferritic steel with the austenitic steel part is glued directly to one another in a materially bonded manner.
  • a particularly secure connection is guaranteed.
  • at least the preferred for the heat exchanger ferritic and austenitic steels are usually easily bonded together cohesively.
  • the ferritic steel is a steel from the group 1.4016.
  • Suitable higher-alloyed ferritic steels with at least 12% Cr content are preferably from the group 1.4000, 1.4002 and 1.4113.
  • Higher alloyed and stabilized steels are preferred from the group 1.4509, 1.4513, 1.4512 and 1.4520.
  • the coolant is gaseous, in particular air.
  • Such exchangers do not harbor the risk of water hammering in the event of corrosion and have particularly high requirements with regard to the heat conduction of the materials in order to achieve a suitable cooling performance.
  • the use of ferritic steels is suitable.
  • a heat exchanger according to the invention can be arranged in a low-pressure branch after an exhaust gas turbine (low-pressure EGR). In this arrangement occur lower mechanical loads and temperature differences.
  • the heat exchanger can also be arranged in a high pressure branch in front of an exhaust gas turbine.
  • the fluid is a particular recirculated exhaust gas or exhaust-air mixture of the internal combustion engine, wherein the fluid temperature in the section in the usual mode of operation is more than 300 ° C, in particular more than 500 ° C.
  • the first connection region has a widening of a passage cross-section in the direction of the exchanger region.
  • an adjustable flap is arranged in the connection area.
  • the exchanger area has a plurality of exchanger tubes.
  • the exchanger region has an exchanger housing through which the coolant can flow.
  • the Berippungselement is arranged in the fluid to be cooled.
  • the austenitic steel is a steel from the group 1.4301 and 1.4404, designations according to DIN EN 100 88-2.
  • the coolant is gaseous, in particular air.
  • the heat exchanger is arranged in a low pressure branch after an exhaust gas turbine.
  • the heat exchanger is arranged in a high-pressure branch in front of an exhaust gas turbine.

He has a first connection area 1 to the feeder of the exhaust gas (or exhaust-air mixture), an exchanger region 2, in which the main part of the heat exchange takes place, and a second connection region 3 for the discharge of the exhaust gas.
  • a controllable by means of an actuator 4 via a mechanism 5 adjustable flap 6 is rotatably supported, by means of which the exhaust gas flow between a bypass channel 7 and a bundle of heat exchanger tubes 8 can be deflected adjustable.
  • the bypass channel 7 and the exchanger tubes 8 are welded together by means of head elements 9, wherein in addition by a housing shell 10 by welding with the head elements 9 a through-flow of liquid coolant exchanger housing is formed.
  • a housing shell 10 by welding with the head elements 9 a through-flow of liquid coolant exchanger housing is formed.

  • the housing shell 10 made of this steel.
  • the exchanger tubes 8, the head elements 9 as well as the second connection region 3 may consist of a ferritic steel. Due to the higher risk of condensation in the relatively cool region of the gas outlet, the second connection region 3 is preferably made of a ferritic steel of stainless and stabilized quality, in particular 1.4512 or 1.4509.
  • the exchanger tubes 8 and / or the bypass channel 7 and / or the head elements 9 are in the case in which they are made of ferritic steel, preferably made of stainless and stabilized quality (in particular 1.4512 and / or 1.4509).
