Definitions
- the invention relates to a shell and tube heat exchanger, in particular for forming an evaporator for an exhaust heat recovery device.
- Heat exchangers are known in different configurations.
- a heat exchanger can be charged with a hot exhaust gas flow in order to transfer a working medium from the liquid phase into the vapor phase, which subsequently relaxes in an expander while performing mechanical work.
- Heat exchangers serving as evaporators may be in the form of a plate stack in which flow channels for the heating medium,
- Heat transfer medium in the form of interruptions in the individual plates of the stacking sequence are created.
- Typical designs provide heat exchangers according to the countercurrent or cross-countercurrent principle. For this purpose, reference is made by way of example to DE 10 2008 029 096 AI.
- Internal combustion engines are such tube bundle heat exchangers, for example, from DE 41 41 051 AI, EP 1 321 644 Bl and DE 10 2009 011 847 AI known.
- GB 501 202 describes a relatively densely packed shell and tube heat exchanger having tubes extending in two vertical planes, a first group of tube arcs each extending in a horizontal plane and a second group of tube arcs extending diagonally between two horizontal planes superimposed one on top of the other. The angles between the pipe bends are therefore 45 °.
- Pipe pieces run in three juxtaposed vertical planes.
- the invention is based on the object, a heat exchanger in
- Evaporator an exhaust heat recovery device usable and have easy to produce, stackable tube windings.
- Evaporator an exhaust heat recovery device usable and have easy to produce, stackable tube windings.
- the holder of the tube bundle heat exchanger should be connected to existing components of an exhaust system with a low design effort. Furthermore, the stacking sequence of the tube windings should allow geometrically simple inlet and outlet tubes for the heat medium.
- the heat exchanger according to the invention despite the possibility of very dense packing and thus the low space required for the
- stackable tube windings in a serpentine design form the basis of the invention.
- the tube windings forming a tube bundle of the heat exchanger which extend between a common inlet space and a common outlet space for the supply and removal of the heat medium, have an alternating sequence of tube pieces and tube bends.
- the pipe bends cause a deflection of the heat medium substantially by 180 ° with respect to an associated arc axis and have the same bending radii.
- Preference is given to a cohesive connection of separately produced pipe sections and pipe bends for the formation of the pipe windings.
- a cohesive connection of separately produced pipe sections and pipe bends for the formation of the pipe windings.
- Tube winding are created in one piece, the pipe bends are produced by a suitable forming process.
- the pipe sections are arranged alternately in two mutually parallel planes, in particular vertical planes.
- only these two levels are provided with pipe sections and no other parallel plane with pipe sections.
- the pipe bends connect the
- each pipe bend advantageously has a first end in the first plane and a second end in the second plane to connect two pipe sections positioned in different levels.
- the pipe bends are in particular obliquely or diagonally on the two planes, advantageously they extend within a pipe arc plane which is approximately or exactly at an angle of 45 ° on the two planes. By approximately, for example, an angular range of 35 ° - 55 °, in particular 40 ° - 50 ° to understand. It is favorable, however, if the angle is 45 °.
- the invention is characterized by thus formed pipe bends for connecting pipe sections of each individual pipe windings, whose
- Arc axes for adjacent pipe bends are in angular position to each other and are designed to extend parallel pipe elbows in next but one neighborhood.
- the angular position of the arc axes of adjacent pipe bends takes an angle in the range of 85 ° - 95 °, preferably of 90 °.
- the tube windings are preferably designed such that each tube piece for the respective tube winding is assigned to a first tube piece group or a second tube piece group.
- a projection direction can be defined, for which the projections of all belonging to a pipe section group of pipe sections are congruent.
- straight pipe sections are preferably used, since these are advantageously easy to manufacture and can be handled to form pipe windings.
- geometrically matching, stackable tube windings can thus be produced in a simple manner, which according to the invention form a zigzag pattern for a cutting plane running perpendicular to the straight pipe sections due to the alternating angular position of the arc axes of the pipe bends.
- an improved stackability of the tube windings is achieved, resulting in a tube bundle heat exchanger with an increased proportion of parallel flow paths.
- These parallel flow paths are then to Realization of the cross-countercurrent principle of the heat-carrying fluid flow with respect to an average flow direction applied substantially perpendicular.
- the inlet for the heat medium is provided at the bottom in the stack and the outlet at the top in the stack, and the medium introducing the heat, in particular an exhaust gas flow, flows vertically or essentially vertically from top to bottom through the stack between the pipe sections or these flows around.
- the pipe bends preferably have a matching geometry, wherein particularly preferably the pipe bends are formed as easy to be produced semicircular arches with a plane extending central line. Deviations from a straight design of the pipe sections and a

In this direction, the main flow direction is effected by the thermal fluid, which occurs in the heat exchange with the guided in the tube winding 1 heat medium. This will be explained in more detail below.

- the bend 7 is a flat semicircular arc, so that the bow axis 17 is defined by the normal vector through the center of the associated semicircle. Nevertheless, they are
- Radial vectors 22.1, 22.2 which extend from a center point 21 to the circular arc section 20, can be determined for sufficiently small circular arc sections 20 along the threading line 18.
- a vector is determined, which determines the contribution to the sheet axis 17, which is associated with the considered circular arc section 20.
- the entire pipe bend 7 associated sheet axis 17 then results from a weighted averaging of the above contributions. The weighting takes place over the circular arc lengths of the circular arc sections 20 used for the determination.
- Figure 4 shows an enlarged view of Figure lb. Sketched are in the transverse direction truncated pipe sections 6.1, 6.2, 6.3, 6.4, 6.5 with
