Definitions
- the invention relates to a heat exchanger having an inner guide for guiding a fluid and having a planteabloomianus for dissipating heat of the fluid, wherein the abcountryianu has a longitudinally extending cavity within which extends at least one end of the inner guide, wherein the tail has an orifice comprising, facing a bottom surface of the cavity for introducing the fluid into a bottom region of the cavity, wherein between a outer surface of the inner guide and an inner surface of the abgradifiess a longitudinally extending flow space for guiding the fluid away from the bottom region is formed ,
- the invention also relates to a method for producing a heat exchanger.
- the heat exchanger is used in an exhaust system of a motor vehicle in order to dissipate as much of the heat as possible of the hot exhaust gas generated in the engine of the motor vehicle, for example by transfer to a heat transfer fluid. A possible overheating of the exhaust system can be avoided.
- the heat taken from the exhaust gas can be used for heating purposes, for example for heating a passenger compartment of the vehicle.
- the heat exchanger is part of a heater or it is connected to a heater, for example in a vehicle.
- the possible uses of the heat exchanger described in this application are not limited to the vehicle sector. Rather, the heat exchanger is in principle suitable for any application in which a fluid, that is, a liquid or gaseous medium, heat withdrawn or supplied. It is an object of the invention to provide a heat exchanger, which is as simple as possible structured and accordingly easy to manufacture and on the other hand, a high efficiency, that is, the highest possible heat transfer rate. This object is achieved with the characterizing feature of claim 1.
- the heat exchanger according to the invention builds on the prior art in that the inner circumferential surface of the sauab fertilianus has a first and a second portion, wherein the first portion has at least two transversely offset ribs and wherein the second portion has at least two transversely offset ribs and wherein at least one rib of the second portion is transversely offset relative to each rib of the first portion, or at least one rib of the second portion is transversely offset relative to each rib of the first portion.
- At least two, three, four, five or six ribs of the first or second section are transversely offset relative to each rib of the second and first sections, respectively.
- each rib of the first section is transversely offset relative to each rib of the second section.
- a rib of a heat exchanger is arranged in the flow region of the heat exchanger component, which increases the effective area of the heat exchanger and thus improves the efficiency of the heat exchanger.
- Each section may, for example, be wavy or rippled. In this case, each ridge or ridge formation forms a rib.
- the ribs of any section may extend parallel to each other and be equidistant. This can promote the most uniform possible flow through the cavity with the fluid.
- the ribs can be elongated.
- the length of each rib may be more than three times or even more than ten times the maximum dimension of the rib across the flowpath.
- a direction transverse to the longitudinal direction is also referred to as a transverse direction.
- the ribs of the two sections are transversely offset relative to one another.
- the inner lateral surface of the heat dissipation body is thus discontinuous at the boundary between the two sections. This promotes the formation of turbulence at the boundary between the sections and thus promotes a mixing of near-surface parts of the fluid with surface-distant parts of the fluid at the transition between the first section and the second section.
- Each rib of the first section may have an end face facing the second section.
- Each rib of the second section may have an end face facing the first section.
- a rib of the first portion is considered transversely offset to a rib of the second portion (second rib) just when the projection of the end face of the first rib on a transverse plane (first projection) and the projection of the end face of the second rib on the same transverse plane (second projection) are offset in the sense that neither of the two projections completely covers the other.
- a transversal plane or transversal plane is a plane perpendicular to the longitudinal direction, ie a plane with a normal vector which is parallel to the longitudinal direction.
- a projection is an orthogonal projection. For example, it may be provided that the first projection covers less than 70 percent, less than 20 percent, or even less than 10 percent of the area of the second projection.
- the second projection covers less than 70 percent, less than 20 percent, or even less than 10 percent of the area of the first projection.
- the two projections do not overlap. The least possible overlap of the two projections is considered advantageous for the generation of turbulence.
- the heat dissipation body may comprise a molded or extruded first segment having the first portion and a cast or extruded second segment having the second portion.
- the heat dissipation body can thus be produced in a straightforward manner, by first producing the first segment and the second segment separately and then joining them together. The abrupt transition from the first section to the second section described above can thus be realized in a straightforward manner.
- the two individual segments can be manufactured, for example, with the help of already designed or existing machines.
- the first segment and the second segment may be identical. In this case, the need to produce different segments is eliminated and a particular That's a cheap manufacturing process.
- the cherriesab Bloommaschine may have more than two identical segments.
- the first and second portions may be arranged such that each rib of the first portion extends to a channel extending between two adjacent ribs of the second portion. In this case, each rib of the first section then merges into a channel of the second section. At the transition from the rib to the channel, vortices may form in the fluid. It can be provided that the rib completely or partially obscures the channel to which it extends. That is, a channel facing end surface of the rib and a transverse cross-sectional area of the channel at its abutting the rib channel beginning or channel end completely or partially overlap. For example, it may be provided that the rib obscures the cross-sectional area of the channel to which it extends more than 20 percent, more than 50 percent, more than 80 percent, or even 100 percent.
- a respective channel extending to a rib of the second section is provided between each two adjacent ribs of the first section.
- the channel formed between the adjacent ribs of the first section thus merges into a rib of the second section at the boundary between the two sections.
- the abrupt transition from the channel to the rib favors the mixing of the fluid.
- the rib completely or partially obscures the channel that extends to it. That is, a channel facing end surface of the rib and a transverse cross-sectional area of the channel at its abutting the rib channel beginning or channel end completely or partially overlap.
- the rib will obscure the cross-sectional area of the channel that extends to it to more than 20 percent, more than 50 percent, more than 80 percent, or even 100 percent.
- the heat dissipation body or at least its inner circumferential surface may have a rotation symmetry axis. This means that the heat dissipation body or at least its inner circumferential surface are converted into themselves in a hypothetical rotation about the rotational axis of symmetry, that is, are invariant under the rotation in question. Such symmetry can bring a high degree of efficiency and also facilitate the production of the cherriesabloom stressess.
- the ribs of the first section and the ribs of the second section may each be elongated and extend in the longitudinal direction.
- the ribs may each be aligned substantially parallel to the longitudinal direction.
- Such a rib structure can be particularly easy to manufacture.
- each of the ribs may have a substantially constant transverse cross section. This means that the transverse cross-section of the rib is substantially constant at least on a portion along the longitudinal direction. This section is referred to as a "constant section ribbed section".
- the length of the constant section rib section may be greater than 50 percent, greater than 80 percent, or even greater than 90 percent of the length of the rib.
- a transversal cross section is a cross section perpendicular to the longitudinal direction.
- the transversal cross section of the rib may be substantially constant in the sense that on the constant sectioned rib section all changes in the transverse section are small compared to the dimensions of the section, for example compared to the width and / or height of the section ,
- the rib portion with constant cross-section substantially has the shape of a finite portion of a geometric body which is invariant under infinitesimal translations in the longitudinal direction.
- a set of geometric points is invariant under infinitesimal translations when an infinitesimal translation translates each of the points to a different point of the same set.
- the rib section with constant cross section or even the entire rib may have the shape of a cylinder. ben.
- the cross-sectional area of the cylinder may have any shape, for example, substantially the shape of a rectangle.
- the ribs of the first section and the ribs of the second section may also be advantageous for the ribs of the first section and the ribs of the second section to extend in the longitudinal direction over the entire relevant section.
- Such a heat dissipation body can be comparatively easy to manufacture.
- the inner guide can contain a combustion chamber or communicate with a combustion chamber. A portion of the heat generated during combustion can thus be dissipated via the heat dissipation body and fed to a destination, for example a passenger compartment of a motor vehicle.
- the inner jacket surface of the heat dissipation body has a third section adjoining the second section with at least two mutually transversely offset ribs, wherein at least one rib of the third section is offset transversely relative to each rib of the second section or at least a rib of the second portion is transversely offset relative to each rib of the third portion.
- Transversal as explained above, means "transverse to the longitudinal direction”.
- a further swirling zone is created, namely at the boundary between the second and the third section.
- the inner circumferential surface of the heat dissipation body has further sections with the features described with respect to the first and the second section.
- the heat exchanger may be manufactured in a process comprising the steps of: preparing a first segment having the first portion; Producing a second segment having the second portion; and joining the first segment and the second segment.
- This method can be particularly uncomplicated to carry out, since the inner lateral surfaces of the two individual segments are structured simpler than the composite inner circumferential surface.
- the heat sink is made in one piece, for example, by a salt core method.
- the first and second segments may be manufactured separately by casting or extrusion molding.
- the segments can also be composed of individual components, for example by welding. If the two segments are identical, they can be successively manufactured using a common manufacturing device. If a casting process is chosen, it can be cast in succession in the same casting mold. The mold can thus be used twice.
- the first segment and the second segment can be joined together by welding, for example. This is a cohesive connection. In this way, at the same time a seal of the cavity at the junction between see see the two segments succeed.

- the end face of the rib 22 facing the second section 20 ' completely overlaps the cross-sectional area of the channel 26' at its channel beginning or channel end facing the first section 20, while the channel 26 'has its cross-sectional area at its channel end or channel end facing the first section 20 Section 20 'facing end face of the rib 22 overlaps only incompletely.
- a channel 26 'of the second portion 20' and a rib 22 of the first portion 20 overlap each other transversely completely.

- the first portion 20 may include at least one rib 22 that is at least 10 percent, at least 20 percent, at least 50 percent, or even at least 100 percent higher than each rib 22 'of the second portion 20'.

- the features explained with reference to FIG. 12 can be analogously transferred to each of the embodiments according to FIGS. 1 to 10.
- the ribs 22 of the first section 20 have a greater height, that is, a larger radial dimension than the ribs 22 'of the second section 20'.
- the distance from the rotational symmetry axis 16 to a rib 22 of the first section is less than the distance from the rotational symmetry axis 16 'to a rib 22'.
- the ribs extend transversely within the cavity 14, 14 'but not necessarily to an opposite surface of the cavity.
- each of the ribs 22 or 22 'in the transverse direction into the cavity 14, 14' protrudes, without hitting another solid structural element.
- Each of the ribs thus has only one continuous surface, not a plurality, which can flow around the fluid.
- the ribs can therefore also be referred to as fins.
- the entire cavity 14, 14 ' is a coherent spatial area. This allows the formation of relatively large-scale turbulence patterns and good heat transfer within the flowing fluid.
