Definitions

  • the invention relates to a plate heat exchanger, in particular Oil cooler, with several nested, each from a heat exchanger plate a circumferential edge web existing flow troughs, which to the Adjacent flow trough close-fitting approaches in the area of aligned, the flow troughs alternately connecting passage openings have, the aligned through openings two each Flow channels with inlets and outlets running transversely to the flow troughs for the heat exchanging media.
  • Known plate heat exchangers of this type have the Advantage of a simple structure, because between the heat exchanger plates effective floors of the nested and liquid-tight interconnected Flow troughs alternately flow channels for the two heat exchanging Media, such as oil and water, result.
  • the heat exchanging Media are fed through an inlet the aligned openings formed across the flow troughs running flow channel alternately fed to every second flow trough, around another, also formed by ventilating passage openings Flow channel withdrawn from the flow troughs and a drain to be fed.
  • Turbulence sheets can be used for a corresponding flow distribution within the Flow troughs are taken care of.
  • the heat transfer mainly depends on the flow rate of the heat exchanging media. Because the flow cross section between the flow channels for the supply and discharge by the sum of Design flow cross sections of the flow troughs for the individual media the heat transfer depends on otherwise identical parameters only depends on the throughput of the heat exchanging media. In the event of of oil coolers, this means that the cooling capacity for a given size may not be sufficient for the maximum oil throughput.
  • the invention is therefore based on the object of designing a plate heat exchanger, in particular an oil cooler of the type described at the outset, that with the same size and the same media throughput, the heat transfer performance can be increased in a simple manner.
  • the invention solves the problem in that at least the inlet side Flow channel for one of the heat exchanging media through at least a partition is divided into axial sections.
  • the flow path for this medium becomes that Flow troughs limited to the section shortened by the partition of the flow channel.
  • This means that the flow cross-section for this medium is extended at the same time the flow path with the same size of the plate heat exchanger decreases and thereby increases the flow rate, which increases the required increase in heat transfer performance.
  • two or more partitions can be used a corresponding flow distribution to the individual flow troughs to force. These partitions are corresponding to the two flow channels for one of the heat exchanging media.
  • the plate heat exchanger according to the illustrated embodiment is composed of individual, nested flow troughs 1, the in each case from a heat exchanger plate 2 forming the trough bottom with a hoisted, peripheral edge 3 are formed, with an extension overlaps the edge 3 of the adjacent heat exchanger plate 2.
  • the flow troughs 1 are with alternating protruding, deep-drawn Provided approaches 4, which have through openings 5. Because the two are flat Approaches 4 are connected to each other in a liquid-tight manner Via the approaches 4 each liquid-tight passages through every second flow trough 1, the aligned openings 5 interacting in pairs Flow channels 6, 7 and 8, 9 for the heat-exchanging media, in the exemplary embodiment form oil and water.
  • the flow troughs 1 are provided between two cover plates 10 and 11, the arrangement so is taken that the cover plate 10 an inlet 12 of the flow channel 6 for carries the oil to be cooled, but the other flow channels 7, 8 and 9 at the end closes.
  • the cover plate 11 supports next to that connected to the flow channel 6 Drain 13 for the cooled oil connected to the flow channel 8 Inlet 14 and the outlet 15 connected to the flow channel 9 for the coolant water. Since the flow channel 6 for the oil in the middle through a partition 16 is divided into two axial sections, as shown in FIG. 2 can be used, the associated, both ends through the cover plates 10 and 11th closed flow channel 7 only as a deflection guide for the oil through the schematic flow arrows is indicated.
  • the invention is not limited to the illustrated embodiment. So they can Flow troughs 1 with conventional turbulence plates or with other guide devices provided for flow distribution within the individual flow troughs 1 his. It would also be possible to further reduce the flow area by additional partition walls 16 in the flow channels 6 and 7 bring about. Naturally, an analog increase can also be made for the coolant the flow velocity through partitions in the flow channels 8 or 9 are provided.
