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.
- the problem with exhaust gas cooling is the high chemical aggressiveness of the exhaust gas and 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 follow-up costs due to the more complex machining operations.
- austenitic steels are usually poor heat conductors, so that heat exchangers of a given cooling capacity build relatively large and heavy.
- 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 a particular recirculated exhaust gas or exhaust-air mixture of the internal combustion engine, said Fluidtempe- in said first terminal portion when in normal operation and in particular is more temperature more than 300 0 C 500 0 C.
- the ferritic part of the heat exchanger essentially corresponds to the first connection region and is welded 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. Further preferably, an adjustable flap can be arranged in the connection region.
- 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. Corrosion of the Berippungsetti regularly brings due to the EJauart not the risk of breakage of coolant in the fluid area with it, 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. When a ribbing element is placed in both the - A -
- 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 disk elements may also preferably be made of ferritic steel, which serves for the heat conduction and thus the overall 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 correspond to the standard DIN EN 100 88-2, to which reference is made for all numbered material designations mentioned in the context of the present invention.
- the part made of ferritic steel with the part made of austenitic steel is directly bonded together by welding or soldering.
- a material connection in particular by a direct or autogenous welding or by a soldering, a particularly secure connection is ensured.
- at least the preferred for the heat exchanger ferritic and austenitic steels are usually easily cohesively connected to one another, in particular weldable or soldered or glued.
- the ferritic steel is a steel from the group 1.4006 and
- the ferritic steel may preferably be a steel from the group 1.1169, 1.0461, 1.0462 and 1.0463, which are low alloy steels and fine grain steels. Suitable higher alloyed ferritic steels with at least 12% Cr content are preferably from the group 1.4000, 1.4002, 1.4006 and 1.4113. Higher alloyed and stabilized steels (with titanium and niobium) 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, lower mechanical loads and temperature differences occur. Alternatively, however, the heat exchanger can also be arranged in a high pressure branch in front of an exhaust gas turbine.
- Fig. 1 shows a spatial, partially cutaway view of a first embodiment of a heat exchanger according to the invention.
- Fig. 2 shows a spatial exploded view of a second embodiment of a heat exchanger.
- the exhaust gas heat exchanger according to FIG. 1 is constructed according to the principle of a tube bundle exchanger. It has a first connection region 1 for supplying 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 discharging the exhaust gas.
- a valve 6 which can be driven by means of an actuator 4 via a mechanism 5 is rotatably mounted, by means of which the exhaust gas flow between a bypass channel 7 and a bundle of heat exchanger tubes 8 can be deflected in an adjustable manner.
- 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.
- At least the first connection region 1, which consists of a widening in the direction of the exchanger area 2 housing consists of a ferritic steel, in particular the steel 1.4006 according to DIN EN 100 27-2.
- the housing shell 10 made of this steel.
- the interchangeable tubes 8, the head elements 9 as well as the second connection region 3 can be made of 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 attachment parts such as holding plates, etc., can be made of ferritic steel, in particular from 1.1169, 1.0461, 1.0462 or 1.0463.
- 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 constructed from two disks 104a, 104b, wherein a ribbing element 108 is provided between the disk 104a, 104b.
- the respective upper disk 104a has a neck-like up-curvature 104c, which adjoins the edge of an opening in the lower disk of the following disk element.
- the individual sockets 104c of the disk elements are in alignment with each other and with the terminals 106, 107 of the cover 105.
- the disk element 104 farthest from the cover has a lower disk 104b which has no breaks.
- 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 thereby ensures an additionally improved heat exchange between the coolant and the discs, in particular turbulence of the coolant being generated.
- 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 on the inner wall of the housing 101 (see in particular FIG. 3).
- the largest possible possible welding or soldering of the disk elements 104 with the inner wall of the housing 101 so that the housing 101 experiences a sufficient cooling performance.
- 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.
- loading elements 109 can be arranged between the disk elements 104, which are surrounded by the exhaust gas and thus provide an enlarged exchanger surface.
- These berip- pung elements 109 may be made of ferritic steel.
