Definitions

  • the invention relates to a plate heat exchanger, in particular an oil cooler, with several nested flow troughs, the same distance apart one above the other, one heat exchanger plate between each two heat-exchanging media as well as deep-drawn control devices made of two form intersecting groups of parallel ribs, the height of which is half mutual distance between the floors corresponds.
  • the arrangement is such that the between two neighboring Trough bottoms, parallel ribs protruding in pairs against each other touch along their backs so that they protrude in pairs against each other Ribs between the adjacent tub floors form partitions that are used for the media passage only in the intersection area with the transverse, ribs projecting on the other bottom side are interrupted.
  • There is also a elaborate floor shape because the floor areas between the intersecting Ribbed coulters additionally shaped to different degrees from the ground level are provided with beads, which make high demands on the deep-drawing behavior of the Material of the flow troughs.
  • a plate heat exchanger with nested Flow troughs to be provided the bottoms of which are each a coulter have parallel ribs.
  • the arrangement is such that the ribs neighboring flow troughs cross each other, between the two floors Distribute the guided medium over the floor area accordingly.
  • two options are proposed. While after one Possibility of crosses of parallel ribs on each other facing sides of the heat exchanger plates are provided, protrude after the another possibility, the ribs from the tub floor against the one above Tub floor on.
  • This disadvantage does not apply to the rib formation only on one side of the tub floor, but then the ribs must be at the mutual ground clearance have the appropriate height, which is a special deep-drawing behavior of the material which requires flow troughs.
  • the flow troughs are made up of droves of crossing ribs aiming for a guiding device for the two heat-exchanging media.
  • the invention is therefore based on the object of a plate heat exchanger, in particular an oil cooler of the type described so that for one of the two heat exchanging media, the flow distribution in the Flow troughs forced by turbulence plates, but for the other medium advantageously by the deep-drawn guide devices of the tub floors is ensured.
  • the invention solves this problem in that the bottoms of the flow troughs each have only a set of parallel ribs and that the each other crossing sets of parallel ribs of immediately adjacent heat exchanger plates either on the side facing each other or on the side facing each other opposite side of the heat exchanger plates are provided and exclusively protrude into the flow paths for one of the two media.
  • the rib height is only half mutual spacing of the floors of directly interlinked flow troughs corresponds and the ribs only on one side of the otherwise projecting flat floor can make considerably less demands on the Thermoforming properties of the tub material are made, what use also higher strength aluminum alloys for the manufacture of such heat exchangers allowed, especially if the deep-drawn approaches to the management of Media between the individual flow troughs in the immediate area protrude into each other in pairs and have a height corresponding to the ribs.
  • These trough floors 2 face each other Passages 5 and 6 assigned in pairs for the heat exchangers Media, such as oil and water.
  • the arrangement is there made so that the passage openings 5 and 6 in the area of deep-drawn Approaches 7 are located, the height of which is half the distance a between the adjacent ones Tub floors 2 corresponds.
  • the openings 5 and 6 are smaller than the bottom of these approaches 7, there is between the bottoms of mutually projecting approaches 7 of adjacent heat exchanger plates 2 a flat system supporting the tight connection of the approaches 7 the respective opening edge.
  • the Approaches 7 in the area of aligned passage openings 5 and 6 alternately opposite plate sides are provided so that the approaches 7th in each case a liquid-tight passage through every second flow trough 1 results.
  • the approaches 7 for the passage of one medium compared to approaches 7 for the passage of the other medium on opposite Sides of the plate.
  • the oil to be cooled through the openings 5 and the water absorbing the oil heat is passed through the passage openings 6, the oil from the inlet 8 to the outlet 9 and the water in countercurrent flow through the flow troughs 1 from the inlet 10 to the outlet 11, so results for the oil by the arrows 12 and one for the water by the Arrows 13 in Fig. 2 indicated flow, with regard to their distribution on the heat exchanger plates from the arrangement of appropriate control devices depends in the individual flow troughs 1. While for the oil flow usual turbulence plates 14 are used, the guide device in the flow troughs 1 in between by deep-drawn ribs 15 formed in the tub bottoms 2.
  • the arrangement is such that the parallel ribs 15 of a flow trough 1 also the coulter parallel ribs 15 of the immediately adjacent flow trough preferably Cross at an angle of 90 °, as shown in FIG. 1 can be.
  • the ribs 15 each in the flow path for the cooling water protrude and have a height h which is half the distance a Trough bottoms 2, the mutually projecting ribs 15 in the area of the crossing points. This is related with the continuous course of the ribs between the crossing points advantageous swirling of the cooling water with it, which probably no closer Explanation needed.
  • the surface of the Heat exchanger plate enlarged, so that overall advantageous heat exchange conditions can be ensured.
  • the invention is of course not based on the illustrated embodiment limited.
  • the cooling oil could also pass through the flow troughs 1 with that formed from the crossing rib coulters Guide device to be directed.
  • the design of the Flow troughs 1 largely free, because the only thing that matters is that Trough bottoms 2 to be provided with parallel coulters, which alternate protrude on opposite sides of the tub bottoms 2 to within each second flow trough 1 a corresponding guide for this To receive flow trough 1 flowing medium.
