Definitions

  • the invention relates to a plate heat exchanger, in particular Oil cooler, consisting of several nested, each from a heat exchanger plate flow troughs formed with peripheral edge web, which alternate with each other via openings for the heat-exchanging media are connected.
  • 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 with each other connected flow troughs alternating flow channels for the two heat-exchanging media, such as oil and water.
  • the heat-exchanging media become one flow trough through the immediately following into the next but one flow trough passed, and that over deep-drawn approaches of the tub floors.
  • the two media can thus each from one of their flow troughs through the deep-drawn approach of the subsequent flow trough for the each flow different medium into the next but one flow trough.
  • With help of turbulence plates inserted in the individual flow troughs can be used for a corresponding flow distribution within the flow troughs be taken care of.
  • the invention is therefore based on the object of a plate heat exchanger of the type described at the beginning with simple constructive means such that the risk of media mixing is reduced, the efficiency improved and a variety of installation options can be achieved.
  • the invention solves the problem in that the passage openings at least the flow troughs for one of the heat exchanging media lie in the area of the edge webs and with each other via at least one outside connected to the edge webs of the nested flow troughs Connection box for the supply and discharge of the medium are connected.
  • the Elimination of the deep-drawn approaches at least for one of the heat-exchanging ones Media also brings an increase in the effective heat exchange area of the heat exchanger plates formed by the trough bottoms itself, so that overall there are favorable construction conditions, especially due to the parallel media flows through the associated flow troughs the flow resistances between the junction box for the Reduce the supply and discharge of the medium.
  • the connection of the junction box on the outside of the edge webs of the nested flow troughs is of course also media-tight. This can be done in the usual way Way, a soldered or welded connection may be provided. A leak Position in the area of such a box connection can, however, only to one Leakage of the medium, but not lead to mixing of the media.
  • connection box for the supply or Derivation of a medium connected flow troughs can be done through the local assignment of the connection box can be determined.
  • connection box for the supply and discharge of a medium on each other provided opposite sides of the flow troughs, so that flows Medium essentially from one side of the flow troughs to the opposite Page.
  • junction box for the feed and Deriving a medium through a common one using a partition in two-compartment subdivided housing formed on one side of the flow troughs is connected, a circulating flow of the medium inside the flow troughs are forced, especially when the over the housing interconnected flow troughs a the partition of the housing continuing guide device for the medium flow.
  • This guiding device which continues the partition of the housing prevents namely a flow short circuit between the parallel side by side the housing connected to the flow troughs for the supply or Derivation of the medium.
  • the plate heat exchanger according to FIGS. 1 to 3 is made of individual, nested Flow troughs 1, each consisting of a Trough base forming heat exchanger plate 2 with a raised, circumferential edge web 3 are formed.
  • the flow troughs 1 are with alternately projecting, deep-drawn approaches 4, have the passage openings 5. Because the area in the area of the front side adjoining lugs 4 are connected to one another in a liquid-tight manner, there are liquid-tight passages through each of the approaches 4 second flow trough 1, as can be seen in FIG. 2.
  • the top flow trough 1 is covered with a cover plate 6, the one Connection 7 for the supply line and a connection 8 for the discharge of one of the two heat-exchanging media, for example oil.
  • the above Oil to be cooled supplied to the connection 7 therefore flows through every second flow trough 1 of the tub stack forming the plate heat exchanger in order can be removed cooled via the port 8.
  • the coolant, z. B. water flows through the flow troughs 1 between the flow troughs 1 for the oil guide.
  • Water is connected to the junction box 3 on the outside 9 for a feed line 10 and a discharge line 11, the connection between the junction box 9 and the flow troughs 1 for the Water flow through passage openings 12 in the area of the edge webs 3.
  • the passage openings 12 can be easily by appropriate slot-shaped recesses of the edge webs 3 are formed.
  • the edge webs 3 in the area of the passage openings 12 between Edge-side incisions to bend outwards to the passage openings Get 12. That via the feed line 10 in the serving as a distributor Junction box 9 pumped water flows through the passage openings 12 into the flow troughs 1 and occurs on the opposite side of the trough via the passage openings 12 in the junction box serving as a collector 9 from where it is discharged via the derivative 11.
  • the oil is accordingly according to the illustrated embodiment in counterflow with the cooling water cooled.
  • the flow distribution within the flow troughs 1 can by guiding devices, for example by turbulence plates 13 in be influenced in a known manner.
  • the plate heat exchanger according to the exemplary embodiment according to FIG. 4 has a common for the supply line 10 and the discharge line 11 of the coolant Housing 14 on by a partition 15 in two chambers 16th is divided, which form the connection box.
  • This housing 14 is on one Attached to the outside of the plate heat exchanger, which like the plate heat exchanger 1 to 3 of nested flow troughs 1 is constructed.
  • Partition 15 continuing guiding devices 17 may be provided.
  • the oil supply takes place again across the flow troughs 1 via connections 7 and 8 for the Supply and discharge.
  • connection box 9 for the Supply and discharge 10 is not only the coolant via junction box 9 for the Supply and discharge 10, 11 fed to the flow troughs 1, but also the oil to be cooled.
  • the connection box 18 with the connection 7 for the supply line and the port 8 for the discharge of the oil are on each other arranged opposite narrow sides of the plate heat exchanger, while the connection box 9 for the coolant on the opposite Long sides of the plate heat exchanger lie, and against each other added.
  • the junction boxes 9 and 18 are each through passage openings in the region of the edge webs 3 of the flow troughs 1 with the flow troughs 1 connected so that the media flows not through deep-drawn Approaches are hindered. The tub bottoms therefore do not form such partially drawn approaches interrupted heat exchanger plates 2.
  • the invention is of course not based on the illustrated embodiments limited, but which already show that the mutual arrangement the junction box for the inlet and outlet 10, 11 of one of the two heat-exchanging media and connections 7 and 8 for the feed and Derivation of the other medium according to the respective conditions can be varied in many ways. Since also the layout of the flow troughs 1 is largely freely selectable, plate heat exchangers can be used for very different space requirements available in a simple manner be put, with an advantageous efficiency, because on the one hand the flow resistances reduced and on the other hand those due to the floor plan of the Flow troughs given the possible heat exchanger surfaces better used can be.
