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.
- the exhaust gas heat exchanger after Fig. 1 is built on the principle of a tube bundle exchanger. 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.
- two connecting pieces 11 are provided for the passage of the liquid coolant through the exchanger housing.
- 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).
- external attachments such as holding plates, etc.
- the heat exchanger of the second embodiment is designed as a disk heat exchanger.
- an outer housing 101 which has a first connection region 102 for connecting a feed for the exhaust gas and a second connection region 103 for connecting a discharge for the exhaust gas, a number of disk elements 104 are arranged.
- the housing 101 also includes a cover 105, on which there are connections 106, 107 for connection of supply lines and discharges of a coolant.
- the disk elements 104 and areas of the housing 101 and cover 105 together form the exchanger area of the heat exchanger.
- Each of the disk elements 104 is made up of two disks 104a, 104b, wherein a ribbing element 108 is provided between the disks 104a, 104b.
- the respective upper disk 104a has a nozzle-like bulge 104c, which adjoins the edge of an opening in the lower disk of the subsequent disk element.
- the individual sockets 104c of the disk elements are aligned with each other and with the terminals 106, 107 of the lid 105.
- the disk element 104 farthest from the cover has a lower disk 104b which has no apertures.
- a total of one of the liquid coolant flow-through cavity is formed by the amount of spaces between each upper plate 104a and lower plate 104b, edge boundaries of the cavities are formed by welding the bent edges 104d of the discs 104a, 104b with each other.
- the coolant flows in each of the disc elements between the one, the port 106 associated with the nozzle, and the other, the port 107 associated nozzle.
- the ribbing 108 flowed around by the coolant ensures additionally improved heat exchange between the coolant and the disks, in particular turbulence of the coolant being produced.
- the intermediate space between two adjacent disk elements 104 is open in each case to the terminal areas 102, 103 of the housing 101 of the heat exchanger at the front side of the disk elements.
- the exhaust gas flows through these intermediate spaces, wherein it is cooled at the large area cooled by the coolant disc elements 104.
- the longitudinal edge regions 104d of the disk elements 104 are bent over and lie partially flat against the inner wall of the housing 101 (see in particular FIG Fig. 3 ).

- the housing 101 is made of a ferritic steel. It may in particular be a cost-effective steel such as e.g. 1.1169, 1.0461, 1.0462 and 1.0463. In the case of corrosion of the housing part 101, there would be no leakage of liquid coolant into the exhaust gas, which is why the use of the cheaper material is made possible here in the interest of a cost-risk assessment.
- the disk stack 104 and also the lid 105 may consist of a ferritic steel. Since these elements provide a separation between the exhaust gas and the liquid coolant, the ferritic steel is preferably a particularly corrosion-resistant grade, such as 1.4000, 1.4002 or 1.4113 or even a high-grade ferritic steel such as 1.4513 or 1.4520.
