  • At least one of the openings has a shape extending in a longitudinal direction and deviating from a circular shape.
  • 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 deviating from a circular shape of the openings is particularly in the given above surface conditioning or surface soldering.
  • An inventive plate element has a profiling, wherein the profiling is arranged in a flow path for influencing the flow of the medium.
  • the profiling is preferably formed by embossing or deformation of the bottom of the plate element.
  • the profiling is undulating, wherein there are a plurality of contact points of the profilings between the profiling of the plate member and the profiling of a structurally identical second plate member, which is fixed to the first plate member.

  • the shaping of the plate member from the metal plate of constant thickness can be done by means of known methods, such as by deep drawing, drop forging or other methods.
  • the material of the metal plate is preferably an aluminum alloy to allow a total of a lightweight construction of a plate cooler.
  • a plate cooler according to the invention comprises a plurality of identical plate elements according to claim 1. This provides the advantages of the shaping of the invention Plate element combined with a cost-effective mass production of a plate cooler.
  • the plate element according to Fig. 1 comprises a bottom plane 1 with two facing in the flow direction of a medium openings 2, 3 of a first type, both of which have a lying in the ground plane 1 edge 2a, 3a.
  • the two first openings 2, 3 are each elongate, with a longitudinal diameter of the openings 2, 3 a little more than 1.5 times a transverse diameter.
  • the flow of the medium is perpendicular to the longitudinal direction of the openings 2, 3.
  • the plate member 1 has in plan view a rectangular shape with strongly rounded corners.
  • the two first openings 2, 3 are both arranged on the same longitudinal side in the corner regions of the rectangle.
  • two openings 4, 5 of a second type are provided, which are similar in shape and opening width of the first openings 2.3.
  • the edges 4a, 5a of the second openings 4, 5 are not arranged at the level of the ground plane 1, but lie in a plane parallel to the ground plane 1 level.
  • the openings 4.5 each associated base surfaces 6, 7, of the plate member, which are arranged offset parallel to the ground plane 1, but in the direction of the vertical axis of the plate member.
  • the vertical axis is as in Fig. 6 defined perpendicular to the drawing plane.
  • the openings 4.5 are present as simple openings of the base surfaces 6, 7 formed. However, they can also have an overhang or other deviations from a simple cutout in the base surface.
  • the base surfaces 6, 7 are partially bounded by a respective rounded edge 6a, 7a of the bottom plane 1 and at the level of the base surfaces 6, 7 partially of a rounded shoulder 8b of a side wall surrounding the plate element 8.
  • the side wall 8 completely surrounds the plate element and has a completely in the same plane lying outer edge 8a.
  • This side wall 8 is also not arranged at right angles to the bottom plane 1, but slightly inclined outwards, which is why it has a conical overall arrangement.
  • a plurality of identical plate elements are stackable, wherein the outer edge 8a in each case bears against a certain height of the side wall 8 of the next plate member and is soldered at this point with this (see Fig. 4 ).
  • the base surfaces 6, 7 each extend from the projection 8b of the side wall 8 to the edge 4a, 5a of the second openings 4, 5.
  • the projection 8b is not in the region of the base surfaces 6, 7 at the same height as in the region of the bottom first why stages 8c occur during the course of the approach 8c.
  • the stacked representation according to Fig. 4 illustrates the surface contact of a base surface 6, 7 at the bottom 1 of the subsequent, rotated by 180 ° plate member results in a surface soldering, which is particularly stable and safe against leakage occurring during the operating period.
  • Fig. 4 illustrates, is formed by the alternating arrangement and sealing soldering a plurality of plate members, a part of a plate cooler comprising a first system A and a second system B of chambers.
  • a first heat-carrying medium for example water and / or glycol

  • the channels 9 are also positioned so that when stacking identical plate elements results in the largest possible number of crossings of channels 9 of a plate member with channels 9 of the other plate member. At these intersections, there are points of contact of the adjacent channels 9, which is ensured by a corresponding dimensioning of their embossing depth.
