Definitions

  • the present invention relates to a plate element for a plate cooler and a plate cooler, comprising a plurality of identical plate elements.
  • Plate coolers are known from the prior art, in which a number of mostly identical, alternately arranged plate elements are arranged one above the other, two separate systems being formed by chambers, a first heat-transferring medium through one chamber system and a second medium through the other chamber system flows.
  • a first heat-transferring medium through one chamber system
  • a second medium through the other chamber system flows.
  • DE 199 39 264 A1 describes a plate-type heat exchanger in a stacked design, in which a plurality of identical plate elements are fixed to one another and soldered to one another along a conical outer edge.
  • the plate elements each have four substantially circular openings within a base region of the plate element, two of the circular openings each having a protruding edge.
  • Each of the cantilevered edges is spaced from the outer edge.
  • This shape in particular the base surface running between the side wall and the second opening edge, makes it easy to ensure that a particularly small proportion of heat-carrying medium is present in a low-flow area of a plate cooler. Areas between the outer edge of the plate cooler and media openings which are particularly unfavorable with regard to the media flow are reduced or eliminated, so that the media mainly between the
  • Openings and thus in its main flow areas is present. Overall, the same exchanger performance can be achieved with a smaller media volume in the plate cooler. As a result, a plate cooler can be made lighter and smaller overall.
  • the plate element can be connected to a second, identical plate element, the connected arrangement being essentially flat against the base surface of the plate element of the second plate element.
  • the structurally identical design of the second plate element enables a particularly economical production of a plate cooler.
  • the plate element is preferably soldered flat to the second plate element at least in the area of the flat system.
  • essentially linear soldering known from the prior art, which is provided by the one-dimensional design of the edges in principle, a much larger contact area of adjacent plate elements of a plate cooler can be soldered in a plate element according to the invention, so that overall a particularly large one Strength and a particularly large long-term stability against cracks and occurring leaks is given.
  • the openings have a shape which extends in a longitudinal direction and deviates from a circular shape.
  • the medium it is easily possible for the medium to flow through a plate cooler consisting of plate elements according to the invention in a particularly wide area.
  • a secure connection of plate elements with a shape of the openings deviating from a circular shape is given, in particular, in the case of the aforementioned flat contact or flat soldering.
  • a plate element according to the invention has a profile, the profile being arranged in a flow path to influence the flow of the medium.
  • a profiling can improve the distribution of the medium flow over the plate element for the purpose of optimizing the exchanger performance.
  • the profiling is preferably formed by embossing or deforming the base of the plate element.
  • the profiling is undulating, with a plurality of contact points of the profilings being present between the profiling of the plate element and the profiling of an identical second plate element which is fixed to the first plate element. This allows a particularly targeted guidance of the medium flow through the profiling.
  • the plate element can be produced overall from a metal plate of constant thickness.
  • the plate element can be formed from the metal plate of constant thickness by methods known per se, for example by deep drawing, drop forging or other methods.
  • the material of the metal plate is preferably an aluminum alloy, in order to enable a lightweight design of a plate cooler.
  • a plate cooler according to the invention comprises a plurality of plate elements of identical construction according to claim 1. This combines the advantages of the shape of the plate element according to the invention with an inexpensive series production of a plate cooler.
  • the plate element according to Fig. 1 comprises a floor level 1 with two openings 2, 3 of a first type opposite each other in the direction of flow of a medium, both of which have an edge 2a, 3a lying in the floor level 1.
  • the first two openings 2, 3 are each elongated, with a longitudinal diameter of the openings 2, 3 being slightly more than 1.5 times a transverse diameter.
  • the flow of the medium takes place perpendicular to the longitudinal direction of the openings 2, 3.
  • the top view of the plate element 1 has a rectangular shape with strongly rounded corners.
  • the two first openings 2, 3 are both arranged on the same long side in the corner regions of the rectangle.
  • two openings 4, 5 of a second type are provided, which have the same shape and opening width as the first openings 2, 3.
  • the edges 4a, 5a of the second openings 4, 5 are not arranged at the level of the floor level 1, but lie in a plane parallel to the floor level 1.
  • base surfaces 6, 7 of the plate element each assigned to the openings 4, 5, which are arranged parallel to the floor plane 1 but offset in the direction of the vertical axis of the plate element.
  • the vertical axis is as in Fig. 6 defined perpendicular to the plane of the drawing.
  • the openings 4, 5 are formed as simple openings in the base surfaces 6, 7. However, they can also have a projection or other deviations from a simple cutout in the base surface.
  • the base surfaces 6, 7 are partially delimited by a respective rounded edge 6a, 7a of the floor level 1 and at the level of the base surfaces 6, 7 partially by a rounded extension 8b of a side wall 8 surrounding the plate element.
  • the side wall 8 completely surrounds the plate element and has one outer edge 8a lying completely in the same plane.
  • This side wall 8 is also not arranged at right angles to the floor level 1, but is inclined slightly outwards, which is why it has an overall conical arrangement. In this way, several plate elements of identical construction can be stacked one inside the other, the outer edge 8a in each case resting against a certain height of the side wall 8 of the next plate element and being soldered to it at this point (see Fig. 4 ).
  • the base surfaces 6, 7 each extend from the extension 8b of the side wall 8 to the edge 4a, 5a of the second openings 4, 5.
  • the extension 8b is not at the same height in the region of the base surfaces 6, 7 as in the region of the base 1 , which is why stages 8c occur in the course of approach 8c.
  • the flat contact of a base surface 6, 7 on the bottom 1 of the subsequent plate element rotated by 180 ° results in a flat soldering which is particularly stable and safe against leakages occurring during the operating time.
  • a plate cooler which comprises a first system A and a second system B of chambers.
  • a first heat-carrying medium for example water and / or glycol, flows through the first system A from one plate opening to the other perpendicular to the plane of the drawing in Fig. 4
  • a second heat-carrying medium for example engine oil, flows through the second system B from one plate opening to the other perpendicular to the plane of the drawing in Fig. 4 .
  • the production of the plate element according to the invention can be done by a conventional forming process, wherein a blank is a simple plate of constant thickness made of an aluminum alloy.
  • the preferred plate element according to 1 to 5 also has a profile 9 of the floor level 1.
  • This profiling essentially comprises a plurality of zigzag or wave-shaped depressions, each of which represents a continuous channel and are embossed into the bottom 1 of the plate element from below.
  • Each of the zigzag channels 9 crosses an imaginary flow path of the medium, which runs from a short side of the plate element to the opposite short side of the plate element.
  • the channels 9 are also positioned so that when stacking identical plate elements there is a large number of crossings of channels 9 of one plate element with channels 9 of the other plate element. At these intersections there are contact points between the adjacent channels 9, which is ensured by appropriate dimensioning of their embossing depth.
  • the plates are preferably soldered to one another at the points of contact.
  • Such turbulence inserts 10 for improving the thermal exchanger performance are known per se from the prior art.
