Definitions
- the invention relates to a heat exchanger for motor vehicles, for example a
- Intercooler or adeckenkeitkühler consisting of tubes, which are each formed of two plates having two opposite longitudinal sides and two opposite narrow sides, wherein one of the longitudinal sides of the
- cooling air represents, and arranged between the tubes heat exchange fins or the like, through which the cooling air flows freely, and from collecting spaces, at the ends of the pipes or the
- the invention relates to a cooling module for motor vehicles.
- the heat exchanger described is known from DE 30 17 701.
- the plates are formed there approximately rectangular.
- the collection spaces are formed by means disposed in the plates breakthroughs which are formed at the opposite ends of the plates.
- Each forming a tube two plates are stacked with their breakthroughs aligned.
- the heat exchange fins are inserted in the spaces between the tubes. There then the cooling air flows freely through.
- the collecting tanks require installation space that is not available for heat exchange. However, in the heat exchanger from DE 30 17 701 also no effective heat exchange takes place in the area of the collecting spaces.
- This heat exchanger belongs to the type in which cooling air can flow freely through the heat exchange fins. There, the ends of flat tubes were bent and placed directly against each other. Collecting boxes can be connected at the ends. The bending area or the connection area of the collecting tanks is also not available there for heat exchange.
- the object of the invention is to provide comparatively larger heat exchanging surfaces in a heat exchanger of the type described above.
- both ends of the tubes preferably open in the longitudinal side remote from the inflow side, which is therefore remote from the inflowing cooling air, it is possible to form the entire or at least a larger surface of the heat exchanger that flows against the cooling air as a heat exchanging surface, whereby the heat exchanging surface comparatively so enlarged.
- the enlargement of the heat exchanging surfaces could be realized.
- the very last ends of the plates or tubes are slightly enlarged in cross-section and lie with their narrow sides against each other. Therefore, the headers can be installed without the provision of a tube bottom.
- tube sheets must be attached to the ends of the pipes to which the collection boxes are to be attached. It is of course possible to open only one end of the tubes in the longitudinal side remote from the upstream side and to provide the other end of the tubes at the narrow side remote from the mouth.
- the geometry or the shape of the plates is therefore not rectangular, as in the prior art, but for example L-shaped, U-shaped or Z-shaped.
- Another embodiment similar to the embodiment with U-shaped plates has plates or tubes whose shape has a convex contour.
- the contour is curved in the direction of the inflow side.
- Two plates each are placed with their edges together to form a tube.
- the plates can be identical. Both plates then have a raised edge on which the two plates abut each other to form the tube and are connected.
- the ends of the tubes or of the plates each have an angled contour in order to be able to open into a corresponding longitudinal side.
- the angled contour piece can be kept quite short - just long enough to connect collection boxes.
- the tubes heat exchange ribs or other heat exchange promoting elements are inserted. Also in the area with the angled or curved contour such elements are arranged. When used as an intercooler, there are inserts in the pipes to promote turbulence formation. However, other formations acting in the same direction, such as deformations or the like, may also be provided here.
- the mentioned connection of the plates and the connection of the plates or The tubes with the heat exchange ribs is preferably carried out by means of soldering.
- the collection boxes can be made of plastic or metal.
- FIG. 1 perspective view of a heat exchanger according to a preferred embodiment
- Fig. 2 view of a pipe section
- Fig. 3 view of a plate piece
- FIGS. 4 - 6 other views of the heat exchanger of FIG. 1;
- FIGS. 7 and 8 are views of a cooling module with a heat exchanger;
- FIGS. 9-11 are structural illustrations of heat exchangers in other embodiments (top or bottom views);
- the heat exchanger shown in the embodiments is used in a motor vehicle. It can be either a cooling liquid cooler exposed to cooling air or else a charge air cooler. Other uses, for example as applied with cooling air oil cooler, are also very well conceivable.
- the heat exchanger shown in a perspective view in FIG. 1 is arranged in front of the motor vehicle. He has a comparatively large inflow area A, which is acted upon by cooling air.
- both ends 4a and 4b of the plates 1a, 1b and the tubes 1 are located on the longitudinal side L2 of the plates 1a, 1b and the tubes 1, respectively, remote from the upstream side A. Therefore, in the preferred embodiment, too U - shaped plates 1a, 1b are spoken, which are used there.
- the collecting boxes 30 are either made of plastic and are mechanically attached They are attached to the ends 4a and 4b or, like the tubes 1 and the metal heat exchange ribs 2 arranged between the tubes 1, aluminum or a suitable aluminum alloy is the preferred choice.
- the plates 1a, 1b have a raised edge 10 and are each assembled into a tube 1 to (later) at their soldered up edges to be soldered.
- Fig. 2 shows a piece of the tube with one end 4
- Fig. 3 shows a piece of a plate 1a.
- the plates 1a and 1b are identical.
- the tubes 1 are assembled in a conventional manner with the heat exchange ribs 2.
- heat exchange ribs 2 or other heat exchanging improvements training in the plate areas 5 are used or arranged, which are angled and lead to the headers 30.
- the resulting heat exchanger block is subjected to a brazing process and thereby combined into a compact block.
- inserts 20 are also located inside the tubes 1.
- the inner inserts 20 do not have to go over the entire tube length. You can also have a distance to the narrow sides S.
- the aforementioned longitudinal sides L1, L2 preferably extend in the transverse direction of the motor vehicle, not shown. However, they could also run in the vertical direction of the motor vehicle.
- FIG. 9 has approximately Z-shaped plates 1 a and 1 b, which each form a tube 1.
- the left-hand end 4a of the plates 1a, 1b or the tubes 1 opens into the longitudinal side L2 remote from the inflow side A.
- the other in the image right end 4b opens in the inflow side A and in the longitudinal side L1.
- FIG. 10 could be considered as an embodiment having somewhat larger heat exchanging surfaces than that shown in FIG. 9.
- L-shaped plates 1a, 1b or tubes 1 are used.
- the left end of the image 4a is located as in the Fig. 9 in the remote from the upstream side A longitudinal side L2.
- the other end 4b is located in the narrow side S remote from the left end 4a.
- the collecting box 30 arranged there is designed to be particularly flat in order not to have to significantly limit the size of the inflow side A.
- a not shown further embodiment has a not on the remote narrow side S, but arranged on the nearby narrow side S collection box 30.
- the tubes 1 have a Flus Separation in the longitudinal direction, so that it flows, for example, charge air to the remote narrow side S and from there back flow.
- the embodiment according to FIG. 11 is similar to that according to FIGS. 1-6. In contrast, however, it shows a convex contour of the longitudinal sides L1 and L2. Again, the entire surface of the plates 1a, 1b can be formed as a heat exchanging surface.
- annular coolers in which the flat tubes are bent over their narrow sides S, which is still difficult to manufacture, especially when inserts are in the flat tubes, the manufacturability was improved or facilitated by the proposal.
- FIG. 1 shows a convex contour of the longitudinal sides L1 and L2.
- the longitudinal sides L1, L2 run slightly apart towards the ends 4a, 4b and seemingly increase the cross section thereof. This is not preferred, but is due to the representation by means of "autoforming.”
- the longitudinal sides L1 and L2 provided with the convex contour run parallel to one another, ie also at the ends 4a, 4b.
- FIG. 7 now shows a view of the inflow side of a cooling module in which the heat exchanger from FIGS. 1 to 6 is located.
- the heat exchanger is a charge air cooler LLK.
- the inflow side of the cooling module is also the upstream side of the heat exchanger.
- the heat exchanger was placed in the lower part of the cooling module. Above this there is, for example, a cooling liquid cooler and other components belonging to the cooling module.
- FIG. 7 makes the enlarged heat exchanging surface of the charge air cooler LLK particularly clear in comparison to the cooling liquid cooler arranged above it.
- Fig. 8 shows the cooling module from the back.
- the intake and exhaust ports of the intercooler LLK can be seen on the left and right, below.
- the total area is bordered by a fan hood V, on which a fan is arranged to suck cooling air through the cooling module.
