Definitions
- the invention relates to a plate heat exchanger consisting of several stacked trough-shaped heat exchanger plates with stepped, circumferential, outer edge, the edges connected by joining, in particular are soldered.
- Plate heat exchangers of this type are known for example from EP 0250439 and 0258236 known.
- the plate heat exchangers are made of individual trough-shaped heat exchanger plates different design, especially different Edge design composed. Such heat exchanger plates are through suitable forming processes, for example deep drawing, are produced. The batch way is designed so that the heat exchanger plates with simply graduated Border design with those with double-tiered border design alternate.
- the heat exchanger plates also differ in their other design in such a way that they are suitable, stacked on top of one another and joined technically connected to form separate flow channels through which the heat-exchanging fluids can flow.
- the edge design is unsatisfactory for a quality soldering process. Since they also do not ensure sufficient rigidity of the heat exchanger plates can, the positioning and fixation of the stacked Plates can often be faulty.
- the object of the invention is a plate heat exchanger of the type described at the outset so that its manufacture becomes easier and in particular a higher quality of the soldering process enables.
- the plate heat exchanger is provided according to the invention to be equipped with the features of claim 1.
- the horizontal gradation of the edge is done by moving the material leads to a higher work hardening. This will make every heat exchanger plate a higher stiffness is given, the accurate stacking and positioning before the soldering process.
- the pressing force is only vertical according to the invention via the horizontal gradation and transferred to the vertical edge so that the heat exchanger plates can not slip during the soldering process, but their target position to keep.
- connection surface main connection surface
- the channel-like depression in the bottom of the heat exchanger plates improves the sharpest possible training of the right-angled outer edge. This is also a contribution to correct positioning and to increase the connection area. By also in this Area of material shift is the rigidity of the heat exchanger plates further increased and crack formation inhibited.
- One particularly too additional effect of the channel-like depression mentioned is that the vertical force F on the edge area or the main connecting surface is concentrated because that between the heat exchanger plates usually arranged slats in the channel-like circumferential recess are pressed and consequently reduce their resistance to the force F.
- the non-functional outer radii in the area of the horizontal gradation have been chosen relatively large to counteract the risk of cracking.
- the invention provides heat exchanger plates with uniformly graded Edge design available, leading to manufacturing advantages to lead.
- the feature of claim 7 causes a more stable design against mechanical Effects, for example rockfall, which occurs relatively frequently, when the plate heat exchanger according to the invention installed in motor vehicles is.
- Claims 10 to 13 additionally lead to a lower overall height of the heat exchanger and less material. Furthermore, the Arrangement of the horizontal gradation in different heights, in connection with the turbulence-generating embossed in the bottom of the heat exchanger plates Surveys a better adaptation of the plate heat exchanger to different Cooling performance parameters. In known plate heat exchangers, at which the individual heat exchanger plates always with the same vertical distances the cooling capacity can be determined by the number of heat exchanger plates, measures to improve the heat transfer etc. can be varied. The invention provides an additional possibility of adapting the cooling capacity to disposal.
- the water side of the heat exchanger is the lower one vertical distance. Due to the narrowing of the flow channel on the water side it affects the flow velocity of the medium and therefore also on the performance.
- all heat exchanger plates are inventive features formed in their bottom with turbulence-generating elevations, these provided in different numbers, design, arrangement and height could be. The height extension within a heat exchanger plate however, should be the same. These features also allow a favorable cooling performance Adaptation.
- the turbulence-generating surveys, their elevation corresponds to the height of the horizontal gradation of the edge also a distance-generating and stability-improving one Function, because each elevation with its upper end at the bottom of the above arranged heat exchanger plate is connected. The compactness of one such heat exchanger has thus been improved

- the plate heat exchanger 1 consists of six heat exchanger plates 2, which are stacked and with a vertical Force F are applied by the weight of a metal block placed on it is produced. Fins 13 are arranged between the heat exchanger plates 2, which serve to improve the heat transfer.
- a quality Soldering all parts of the plate heat exchanger 1 as in Fig.1 is shown is the application of a force F to the stack and in particular of great importance to the marginal area.
- the slats 13 are in Edge area pressed into the channel-like recess 6 worked into the base 5.
- the Main connecting surface 3 between the heat exchanger plates 2 is through the lower edge of the respective upper heat exchanger plate 2a and the horizontal Gradation 4 in the edge of the heat exchanger plate located below it 2b formed. On this surface 3, pressure soldering is possible, the one better quality of the solder joint guaranteed.
- the main interface 3 is due to the vertical connecting surface between the legs 12 has been expanded or enlarged, in which the solder runs and ensures an additional seal.
- Each heat exchanger plate 2 has the same edge formation, as can be seen particularly from FIGS. 1 and 2. 2 shows further important details. As a convenient dimension for the width b of the circumferential channel-like depression 6 2mm determined and provided.
- the outer radius 7 of the lower outer edge 8 could be minimized, which had a positive effect on the enlargement of the main connecting area 3 affects.
- the horizontal one created by material shift Gradation 4 has a sharp edge 41 on the inside and outside a rounding 42 with a correspondingly large radius.
- the edge design also has a distance from the horizontal gradation 4 a kink outwards.
- Figure 3 shows a further gradation 10 of the edge with a vertical edge finish 11.
- training already mentioned such as channel-like deepening 6, horizontal gradation 4 with the inner edge 41 and the rounding 42 from this figure.
- the Fig.4 shows a plate heat exchanger 1, which is already by brazing is connected to a finished block.
- existing slats 13 were not drawn.
- the separation of the Flow channels 14 for example oil and water is in this embodiment this has been ensured that the attachments for the Ein and The fluids run out in opposite directions from a horizontal plane are trained.
- the flow channels 14 thus sealed off from one another then lead into viewed in the vertical direction, alternating e.g. Oil or water.
- the area of the heat exchanger 1 is included the coolant inlet side (water).
- the water flows through the Plate heat exchanger 1 according to the arrows 15 shown.
- the flow channels 16; 17 have different cross-sectional areas.
