Definitions
- the invention relates to a heat exchanger, in particular an exhaust gas heat exchanger for motor vehicles according to the preamble of claim 1 - known from DE-A 199 07 163.
- the well-known exhaust gas heat exchanger is a welded construction made of stainless steel and has a Housing jacket, a tube bundle with exhaust pipes and tube sheets on.
- the Tubes are with their tube ends in punched openings of the tubesheets welded, and the tubesheets are in turn with the housing shell welded.
- hot exhaust gas flows around the pipes and inside the housing shell flows a liquid cooling medium, d. H. one Coolant, which removed the coolant circuit of the motor vehicle becomes.
- the known exhaust gas cooler is alternately charged with hot exhaust gases, depending on whether an exhaust gas recirculation valve in an exhaust gas recirculation line is open or closed.
- the pipes take the temperature of the hot exhaust gases, while the housing shell the coolant temperature which is much lower than the exhaust gas temperature.
- the pipes are firmly on both sides in the housing shell clamped, d. H. the system is statically indefinite.
- the pipes stretch more than the housing shell and thus cause thermal Tensions, especially in the area of Pipe / tube sheet joints.
- the tube sheets due to buckle the pipe stretches, d. H. deform elastically so that the Tubes are subjected to bending.
- the tubesheets are production-related only a maximum thickness of the order of 1 to 2 mm, because the hole punching for the production of the openings at thicker tube sheets Poses problems. Due to the changing bending stress of the Pipes it comes to fatigue of the pipe material in the area the tubesheets and sometimes to cracks in the pipes.
- the tube sheet several layers, d. H. built up of several sheets that are firmly together are connected, advantageously by welding or soldering.
- a so-called laminate floor is created, which is resistant to bending stresses, d. H. yourself no longer buckles under the pressure of pipe expansion.
- the pipes are thus no longer subjected to bending stress, but only one manageable Pressure.
- the stress of the heat exchanger This significantly reduces the risk of material damage.
- the laminate floor by punching (Punching) can be made by punching the layers individually become. Each layer thus has a maximum sheet thickness, the punching the openings for receiving the pipe ends readily permits.
- Fig. 1 shows a single pipe / floor connection 1 between a tube sheet 2 and an exhaust pipe 3.
- the tube sheet 2 consists of two layers, an upper layer 4 and a lower layer 5, which are firmly connected to each other in a manner not shown, so they do not can slip against each other.
- the exhaust pipe 3 only partially shown has a pipe end 3a, which is flush with the upper layer 4 and connected by a laser weld 6 all around tight and tight with the upper layer 4.
- This pipe / floor connection 1 is part of a Abgastageübertragers, as described in the aforementioned DE-A 199 07 163.
- the exhaust gas heat exchanger according to the invention can be used in particular for exhaust gas recirculation in motor vehicles, ie the pipes 3 are traversed by hot exhaust gases of the internal combustion engine and cooled outside by the coolant of the cooling circuit.
- Tubes and tubesheets are made of stainless steel.
- FIG. 2 shows a perspective view of a tube plate 7 according to the invention, ie a so-called laminate floor, which is constructed from four layers or layers 7.1, 7.2, 7.3., 7.4. All four layers 7.1. to 7.4 are identical, ie they have the same contour and the same hole pattern, ie a tube matrix 8. Each individual layer preferably has a sheet thickness of approximately 1.5 mm, ie the entire tube sheet 7 has a thickness of 6 mm.
- the tube matrix 8 is produced individually for each individual layer 7.1, 7.2, 7.3, 7.4 by punching. Thus, the critical for punching plate thickness is not exceeded. All layers are made of stainless steel, are stacked after punching each other and preferably welded together, for. B. by resistance or cold welding.
- the tubes 3 described in FIG. 1 are inserted into the tube matrix 8 of the tube bottom 7 and welded to the front side.
- the laminate floor 7 is inserted with the tube bundle in a manner not shown in a housing shell and peripherally welded to the housing shell.
- the tubes 3 set their thrust on the tubesheet 2 or 7, which is held by the housing.
- the tube sheet 2 or 7 will not deform under this load, ie not buckle, so that the tubes maintain their straight alignment and are not bent. A bending stress of the tubes thus essentially does not occur.
- Fig. 1 shows an example of a tube sheet with two layers
- Fig. 2 a tube sheet with four layers.
- the number and thickness of the changed individual layers and adapted to the respective stress become.
- a tube sheet according to FIG. 2, d. H. with a thickness of about 6 mm and the illustrated tube matrix of a thick sheet not produced by punching - it would have a more complex manufacturing method choose, for. B. Eroding or milling.
