Definitions
- the present invention relates to a plate heat exchanger, in particular an oil cooler for an internal combustion engine, with a plurality of stacked, wave-shaped heat exchanger plates according to the preamble of claim 1.
- a cover plate which has at least one point a downwardly directed bulge or molding and engages with this formation in an opening of a heat exchanger plate arranged thereunder.
- a disadvantage of the cited prior art is that the cover plate in itself and in particular the formations have only a comparatively low stability.
- the present invention therefore deals with the problem of providing a plate heat exchanger of the generic type, an improved or at least one alternative embodiment, which is characterized in particular by an increased stability with respect to a cover plate.
- the present invention is based on the general idea, downwardly directed bulges or formations on a cover plate of a Plate heat exchanger to provide a crossed embossed geometry, so that the cover plate, in particular in the region of their downwardly directed formations which may be formed complementary to openings of a heat exchanger plate arranged underneath, have a significantly increased rigidity or stability.
- the plate heat exchanger according to the invention which may for example be designed as an oil cooler for an internal combustion engine, has in a known manner a plurality of stacked, trough-shaped heat exchanger plates, each having a plurality of openings for a first and second fluid separated therefrom, for example, oil and cooling water ,
- the upper cover plate now has the inventively crossed embossed formations, which are preferably complementary to the openings of the below
- dome-shaped shape have a significantly increased stability, since the crossed embossed shape in addition to curved in different directions forms also kinks or edges that increase the rigidity of the molding, similar to body parts for a motor vehicle.
- the crossed embossed formations can be as well as the previously known dome-shaped formations by means of a stamping or
- thermoforming cost-effective and technically simple but give the cover plate and thus the entire plate heat exchanger, the desired higher rigidity.
- the heat exchanger plates are formed as deep-drawn sheet metal parts and have a wall thickness of about 0.5 mm.
- Deep-drawing refers to a train-pressure-forming a sheet metal blank in a hollow body open on one side, wherein generally a deep drawing with tool and deep drawing with active media, eg. by means of water.
- the deep-drawn heat exchanger plate shows in particular mutually shifted molecules, resulting in
- the crossed embossed formations in the cover plate have a slot-shaped shape with an orthogonal thereto extending short web.
- a geometric design provides a particularly high rigidity, wherein the shape of the formations is of course adapted to the underlying openings. It is also conceivable here, of course, that the length of the web extending to the slot-like shape of the molding corresponds approximately to the width of the oblong hole or slightly more.
- Fig. 2 shows a cover plate according to the invention with crossed embossed
- FIG. 3 is a view as in Fig. 2, but in a view obliquely from below,
- Fig. 4 is a representation as in Fig. 2, but in another
- Fig. 5 is a representation as in Fig. 4, but in a view obliquely from below.
- an inventive plate heat exchanger in particular in the manner of an oil cooler for an internal combustion engine, a plurality of stacked, trough-shaped and joining technically tightly interconnected heat exchanger plates 2.
- a cover plate 3 is provided.
- the individual heat exchanger plates 2 each have a plurality of openings, not shown, and for a first and a second fluid separated therefrom, wherein the first fluid, for example. Oil and the second fluid, for example. Coolant, in particular cooling water, may be.
- the upper cover plate 3 is now embossed with crossed
- Moldings 4 provided (see also Fig. 2 and 3), which formed complementary to the openings of the heat exchanger plate 2 arranged underneath and joining technical tightly connected to this, in particular can be soldered.
- the cross-shaped formed formations 4 these have a significantly increased stability or rigidity in comparison to previously known, in particular dome-shaped formations, as a result of which the cover plate 3 and with it the entire plate heat exchanger 1 can be made significantly stiffer.
- the heat exchanger plates 2 are usually formed as deep-drawn sheet metal parts and have a wall thickness of about 0.5 mm, whereas the
- Cover plate 3 is also formed as a deep-drawn sheet metal part, but usually has an at least slightly thicker wall thickness in the range of about 0.8 mm.
- the provided in the heat exchanger plates 2 openings are usually used as oil or coolant passages between the individual heat exchanger plates 2.
- a total of four provided openings are two of them for the first fluid, eg. Oil , And two of them for the second fluid, for example, coolant, reserved.
- the individual heat exchanger plates are not only in the region of their openings, but in addition also connected to an outer edge 5 joining technology tightly connected to each other, in particular soldered together.
- FIGS. 2 and 3 As shown in FIGS. 2 and 3 can be seen, have the crossed embossed
- the web 6 may have approximately the width of the elongated hole of the molding 4 or slightly be shorter or longer. By the web 6, it comes in the region of the formation 4 to an edge formation, which increases the stiffness of the cover plate 3 in the region of the crossed embossed formations 4 similar to the body in motor vehicles.
- the cover plate 3 may have drainage holes 7, which ensure a higher reliability.
- FIGS. 4 and 5 embodiments are shown in which the crossed embossed formations 4 of the cover plate 3 are complementary to
- Coolant openings 8 of the underlying heat exchange plate 2 are formed and joined by joining technology, in particular soldered, are. At the same time, at least one of the cooling liquid openings 8, in this case the cooling liquid opening 8 ', is surrounded by a first bead 9 and a second bead 10, which effect a separation of the two media in the plate heat exchanger 1. At the same time a nozzle 1 1 is formed at certain drainage holes, which also unintentional mixing of the two in the
- Plate heat exchanger 1 used media, such as water and oil prevented.
