Definitions
- Heat exchangers in particular for a motor vehicle
- the invention relates to a heat exchanger, in particular for a motor vehicle, according to the preamble of claim 1.
- a heat exchanger which has fins with inclined gills, which cause the air passing over the fins to be deflected.
- the parallel gills are each arranged between two tubes arranged at a height in the form of rectangular blocks. The gills increase the air-side heat transfer.
- the object of the invention is to improve such a heat exchanger, in particular to improve the heat transfer.
- a heat exchanger is provided for heat exchange between a first and a second medium, in which the first medium can flow through a plurality of tubes arranged in parallel and the second medium between the tubes and fins arranged transversely to the tubes.
- the first medium can be a coolant for cooling an internal combustion engine and the second medium can be air.
- the heat exchanger can also be used for any other media.
- the object of the invention is advantageously achieved in that the gills are adapted to the flow path of the second medium.
- This increases the heat exchange between the first and the second medium and thus improves the performance of the heat exchanger, as a result of which the structural depth can be reduced and thus the costs and the weight are reduced.
- the gills running perpendicular to the direction of flow of the second medium and parallel to one another preferably project substantially up to the tubes, as a result of which gill arrays are formed with boundary lines corresponding approximately to the shape of the tubes, which optimize the distribution of the second medium.
- the gill arrays have a circular arc-shaped boundary line in some areas and in the case of elliptical tubes an approximately elliptical boundary line in some areas.
- At least one gill field in particular in a peripheral region, is provided between two adjacent tubes arranged at the same height in the flow direction of the second medium, in particular in a peripheral region.
- An area without gills is preferably provided between two tubes which are adjacent in the flow direction of the second medium.
- the flow resistance in the elongated gill fields pushes the second medium into the non-gilled areas after the pipes, in which there is good heat conduction in the fin, and the heat transfer is increased in these low-flow areas.
- the heat conduction thus takes place not only transversely, but also along the direction of flow of the second medium.
- an area without gills is preferably provided in the middle of a rib. This increases the stability of the fin and at the same time improves the heat conduction transversely to the direction of flow of the second medium, as a result of which the fin efficiency is increased.
- the outermost tubes are surrounded on three sides by gills, i.e. the gill fields between the two edges (seen in the direction of flow of the second medium at the front and back) are not interrupted.
- 1A is a perspective, partial representation of the
- FIG. 1B shows a top view of FIG. 1A, showing the heat conduction in the flow direction
- Fig. 4 shows a third variant
- FIG. 5 shows a perspective, partial illustration of the heat exchanger from FIG. 1A.
- a heat exchanger 1 according to the invention in the present case a radiator of a motor vehicle, has a plurality of tubes 2 arranged in parallel, through which a coolant flows, which dissipates heat to the air, and a plurality of ribs 3 arranged in parallel to one another, which in regions 4 are provided with gills 5, which gill fields 6 bil. the.
- the round tubes 2 according to the present embodiment penetrate the ribs 3 vertically.
- the gill fields 6 cause a deflection of the air sweeping over the ribs 3 (see FIG. 1), the direction of flow of which is indicated by two arrows in FIG. 5 and which is essentially perpendicular to the gills 5.
- the gill panels 6 are designed such that they are designed to be continuous from the outside in the edge regions 10 of the heat exchanger 1 between two adjacent tubes 2 of the first row 11 lying at the same height in the flow direction of the air, as shown in FIG. 1A and 1 B can be seen.
- the gill panel 6 surrounds a tube 2 of the second row 12 from the outside on three sides.
- no gills 5 are provided between two adjacent tubes 2 as seen in the flow direction, as can be seen in FIGS. 1A and 1B, reference being made to this gill-free region as region 7.
- This area 7 improves the heat conduction in the fin in the flow direction in the low-flow area, namely, seen in the flow direction of the air behind a tube 2.
- a continuous area 7 ′ without gills 5 is also provided between two middle rows 13 of tubes 2, which are viewed at the same height, but offset from one another, in the direction of flow of the air. This interruption ensures the stability of the fins 3. Since only four rows 14 of tubes 2 are provided in the present exemplary embodiment, the middle rows 13 are identical to the second rows 12.
- the gill panels 6 are each as close as possible to the tubes 2, namely as far as is technically feasible from a production point of view, so that there are circular arc-shaped boundary lines of the gill panels 6 in the corresponding areas.
- the gill panels 106 with their gills 105 are configured continuously between two adjacent tubes 102, viewed at the same height in the flow direction of the air, as can be seen from FIG. 2.
- the gill fields 106 end viewed in the flow direction of the air, before a pipe 102 arranged offset to this ends. is sufficient so that rows 114 are formed in each case, in which tubes 102 and gill panels 106 alternate and which are interrupted by regions 107 '.
- these areas 107 ′ correspond to the area of the exemplary embodiment described above. The interruption ensures the stability of the ribs 103 and improves the heat conduction in this area 107 ', so that the rib efficiency increases.
- the gill panels 106 are brought as close as possible to the pipes 102, so that regions of the gill panels 106 which are circular in shape in some areas result.
- this second variant is in principle a combination of the arrangement of the gill fields 6 according to the exemplary embodiment and the arrangement of the gill fields 106 according to the first variant, the regions 7 and 107 'in which none Gill fields 6, 106 are provided, both the exemplary embodiment and the first variant can be combined with one another.
- a first row 211 is provided in the edge area 210 of the ribs 203, in which tubes 202 and gill panels 206 alternate, from the second row 212 tubes 202 with two gill panels 206 and an area 207 arranged in between without gills alternate 205 from. Areas 207 'without gills 205 are also provided between the individual rows 214.
- the third variant of the exemplary embodiment is described below with reference to FIG. 4.
- identical or functionally identical parts are provided with reference numerals 300 higher than in the exemplary embodiment described first.
- two rows 314 of tubes 302 are provided, with two tubes 302 each being aligned with one another when viewed in the direction of flow of the air.
- the ribs 303 have gill panels 306, the gill panels 306 being brought as far as possible to the tubes 302 and thus having a boundary line corresponding approximately to the tube shape.
- regions 307 viewed in the flow direction of the air, are arranged between two tubes 302, in which no gills 305 are provided.
- a region 307 'without gills is provided between the two rows 314. Instead of the 'broken through this area 307 gilled panels ⁇ ⁇ 306 air through gills fields are also seen in the flow direction possible (according to the first variant).
- Heat exchanger 102, 202, 302 tube, 103, 203, 303 rib area, 105, 205, 305 gill, 106, 206, 306 gill panels, 7 ', 107', 207, 207 ', 307, 307' area 0, 210 Border area 1,211 first row 2, 212 second row 3 middle row 4, 114, 214, 314 row
