Definitions
- the invention relates to a flow channel of a heat exchanger through which a medium can flow in a flow direction.
- the invention also relates to a heat exchanger with flow channels according to the preamble of claim 40.
- Flow channels for heat exchangers are from a first medium, for. B. flows through an exhaust gas or a liquid coolant and delimit this first medium from a second medium to which the heat of the ⁇ first medium is to be transferred.
- Flow channels of this type can be tubes with a round cross section, rectangular tubes, flat tubes or pairs of disks in which two plates or disks are connected at the edge.
- the media that are in heat exchange with each other are different, e.g. B. flows in the tubes a hot, soot-laden exhaust gas, and on the outside the exhaust pipes are flowed around by a liquid coolant, which results in different heat transfer conditions on the inside and the outside of the pipes.
- a heat exchanger in particular a coolant / air cooler with flat tubes and corrugated fins, in which the flat sides of the flat tubes have a structure consisting of structural elements.
- the structural elements are elongated, arranged in a V-shape in rows transversely to the coolant flow direction or transversely to the longitudinal axis of the tubes and act as eddies to increase the heat transfer on the coolant side.
- the vortex generators are embossed in both opposite pipe walls and protrude inwards into the coolant flow.
- the rows of vortex generators on one flat tube side are offset in the flow direction compared to the rows on the other flat tube side. This also makes it possible to dimension the inwardly projecting height of the vortex generators to be greater than half the inside width of the flat tube cross section.
- EP-A 1 061 319 has disclosed a flat tube for a motor vehicle radiator, which has a structure on its flat sides which consists of individual elongate structural elements arranged in rows.
- the structural elements which are arranged in rows in particular, are essentially opposite one another on the one and the other side of the flow channel, that is to say seen in the flow direction, are each arranged approximately at the same height.
- the opposing structural elements or rows can also be offset from one another in the direction of flow, but only to the extent that there is still an overlap.
- Structural elements that protrude from one and the other heat exchanger surface and protrude into the flow channel thus simultaneously intervene in the flow and cause a swirling of the flow, which results in an improvement in the heat transfer on the inside of the flow channel.
- a soot deposits prevented.
- the pressure loss is kept within reasonable limits.
- the flow within the flow channel is thus disturbed from both sides at the same time, ie both boundary layers are detached at the same time, which leads to a particularly strong turbulence.
- the opposing structural elements or rows of structural elements can also be located on the outside of the flow channel - on the coolant side in the case of an exhaust gas cooler.
- a row with structural elements is formed by one or more structural elements which are arranged essentially next to one another in the direction of flow P.
- a row can also be formed by a single structural element, next to which, for example, no further structural elements are arranged.
- the structural elements can be straight or curved, ie with a constant or variable outflow angle to the flow direction.
- the change in the outflow angle from a relatively large inflow angle to the outflow angle results in a “gentle” deflection of the flow and thus a somewhat reduced pressure loss.
- the structural elements can be arranged offset within a row, ie the Although structural elements are arranged in a row running transversely to the flow direction, they are staggered in the flow direction, which also results in the advantage of a lower pressure loss.
- opposite rows ie one or the other side of the flat tube
- can be staggered in the flow direction but there is always an overlap between the two rows. direction, there is less pressure loss. If the opposite structures touch and are connected by welding or soldering, the strength can be increased.
- the structural elements are not arranged in a row at uniform intervals; rather, these rows have gaps which are opposite structural elements on the opposite side and thus “fill” these gaps - in plan view. This also gives the advantage achieved a lower pressure drop.
- knobs and / or webs can also be stamped outwards or inwards (viewed in flow direction P) in order to achieve a "support” and thus an increase in strength.
- the structures that produce vortices can also assume this function in whole or in part.
- the essentially opposite heat transfer surfaces and in particular the structural elements arranged thereon are curved.
- the advantages according to the invention are achieved in particular in the case of tubes with a circular or oval cross section.
- the essentially opposite heat transfer surfaces are primary thermal surfaces.
- the heat transfer surfaces are thermal secondary surfaces, which are formed in particular by ribs, webs or the like, preferably soldered, welded or clamped to the flow channel.
- the height h of the structural elements is in the range from 2 mm to 10 mm, in particular in the range from 3 mm to 4 mm, preferably around 3.7 mm.
- the flow channel is rectangular and has a width b which is in particular in the range from 5 mm to 120 mm, preferably in the range from 10 mm to 50 mm.
- a hydraulic diameter of the flow channel is in the range from 3 mm to 26 mm, in particular in the range from 3 mm to 10 mm.
- At least one, in particular each row of structural elements comprises a plurality of structural elements.
- the aforementioned flow channels are provided as flat, round, oval or rectangular tubes of a heat exchanger, advantageously an exhaust gas heat exchanger.
- the arrangement of the structural elements according to the invention that is to say advantageously their embossing into the inner tube walls, results in an increase in the performance of the heat exchanger.
- the structural elements arranged in rows for exhaust gas heat exchangers are particularly advantageous because soot deposits are also avoided in the interior of the flat tubes.
- a coolant flows around the outside of the exhaust gas pipes, which coolant circuit is taken from the coolant circuit of the internal combustion engine emitting the exhaust gases. It is also possible for the structures to be embossed in plates or disks in order to use them to produce heat exchangers.

- the structural element 44 which is likewise flowed toward in the direction of the apex 44c in accordance with the arrow P, initially causes a slight flow deflection, which is then reinforced due to the legs 44a, 44b that are curved into the flow.
- the elements according to FIGS. 12a and 12b can be used in all the arrangements shown above, where two structures arranged in a V-shape can be found again.
