Definitions

  • the invention relates to a plate heat exchanger for heat-exchanging media in separate circuits, consisting of individual heat exchanger plates stacked one inside the other and metallically connected and having openings, which form a package which is formed vertically by flow channels for the heating or cooling medium formed by the openings and of flow channels for the / the is pierced other / s medium / media, which are separated from one another and starting from which the heating or cooling medium and / the other / propagates n medium / media formed by two heat exchanger plates channels, of which at least some have an inner insert.
  • a plate heat exchanger of this type is known for example from EP 819 907 B1.
  • This Plate heat exchangers are in the heat exchanger plates, which are the horizontal channels for heating or form cooling medium, knobs or similar projections have been impressed.
  • the knobs of neighboring Heat exchanger plates touch and are soldered together to ensure the strength of the plate heat exchanger to raise.
  • Such knobs have generally proven themselves and will continue to do so very often because they cause practically no noticeable loss of pressure. It has it turned out, however, that the durability of such a design for extreme loads, due to temperature shocks as well as extreme operational vibrations, not always is sufficient.
  • the object of the invention is to improve the durability of the plate heat exchanger inside, without significantly increasing the pressure loss of the medium flowing through the channels.
  • the inner insert is an additional plate, the guide channels with at least one inlet and one outlet, that of a flow channel of one medium lead to the other flow channel of the same medium, the guide channels free sections of the additional plate with an adjacent heat exchanger plate and the guide channels with the other adjacent heat exchanger plate of the same channel metallic are connected.
  • the plate heat exchanger according to the invention leads to the following advantages.
  • the durability against temperature shocks and extreme Changes in temperature and mechanical stress are significantly improved because the additional plate is connected on both sides, that is, to both heat exchanger plates.
  • the connection areas are much larger than in the prior art, which means for durability, for example of soldered connections.
  • the majority of the guide channels should be from one Flow channel of one medium directed to the other flow channel of the same medium his.
  • the additional plates of the plate heat exchanger according to the invention can be in all of its Channels.
  • the additional plate has four openings, which are in relation to their position with the flow channels openings in the heat exchanger plates. Regarding their function, they are two openings in the additional plate connected by means of the guide channels are larger than the corresponding ones Openings in the heat exchanger plates and with one on the arrangement of the guide channels adapted form. It has been determined through extensive testing that this measure played a significant part in the fact that the pressure loss could be reduced further.
  • the shape of the openings mentioned and the arrangement of the guide channels should be adapted to one another his. In a preferred exemplary embodiment, these openings have a shape that deviates from the circular shape Shape up. In particular, the openings have bulges in the direction of the indentations. or exits of selected guide channels.
  • the other two openings in the additional plate, which are intended for another medium and which are not connected by means of guide channels are identical in shape to the openings in the heat exchanger plates.
  • the claim 4 provides that the additional plate in at least one of the channels for heating - or cooling medium. It has been shown in practice that mainly the channels for the Heating or cooling medium against extreme temperature shocks and temperature changes were problematic in terms of durability. Claim 4 counteracts this.
  • Claim 5 provides that at least the channels in plate heat exchangers for more than two media for the heating or cooling medium connected to a channel of one medium on one side and on the other border on the other side to a channel of the other medium equipped with an additional plate are. This is advantageous because in the transition areas from one medium to another the temperature differences and thus the stresses are greatest.
  • some guide channels have branches and others Guide channels are formed without branches. This allows the arrangement of the guide channels be adapted and optimized to the respective application.
  • the branches can be between the edge of the heat exchanger plate and the flow channels are located.
  • the corner regions are in the case of essentially rectangular heat exchanger plates of the heat exchanger is intensively involved in the heat exchange, which increases the performance of the same is improved.
  • Investigations carried out by the applicant show a very homogeneous distribution heat exchange over all areas of the heat exchanger plates and the additional plates.
  • Claim 8 describes an advantageous arrangement of the guide channels, which consists in that some Guide channels formed continuously from one flow channel to the other flow channel and other leadership channels are significantly shorter, with their exit and entry away from the flow channels is arranged.
  • Claim 9 represents an advantageous additional measure and stipulates that the additional plate knobs or similar projections should have the same height as the guide channels and which are connected to the adjacent heat exchanger plate.
  • the knobs are near the Flow channels or arranged in surfaces of the additional plate not so closely occupied with guide channels and therefore support these areas additionally.
  • the additional plate according to the invention can be much thinner than the heat exchanger plates and thus be designed to save material and weight.
  • the thickness is Heat exchanger plates 0.5 mm and those of the additional plates only 0.3 mm.
  • the additional plate is in a channel 5 of the plate heat exchanger 1st Of the two heat exchanger plates 2, which form the channel 5, 1, the lower plate 2 can be seen in Fig..
  • the top plate 2 was not drawn in this view in order to be able to see the details of the additional plate 6 .
  • the additional design of the additional plate 6 corresponds approximately to that of the heat exchanger plates 2 .
  • the heat exchanger plates 2 have a raised edge 13 , while the edge 7 of the additional plate 6 in the exemplary embodiment is smooth and the additional plate 6 is dimensioned such that it fits straight into between two heat exchanger plates 2 .

  • the arrows 21 indicate that it is assumed that the heating or cooling medium K enters the channel 5 , in which the additional plate 6 shown in FIG. 1 is located, from the opening 15 or the corresponding flow channel 4 .
  • the heating or cooling medium K leaves the channel 5 again in order to flow through the plate heat exchanger 1 further.
  • the openings 17 and 18 arranged in the other two corner areas 23 and 25 in the heat exchanger plates 2 and 33 and 35 in the additional plate 6 are intended for another medium which is in heat exchange with the heating or cooling medium K.
  • These openings 17 and 18 ( 33 and 35 ), which in turn form flow channels 4 each have a ring 20 in the exemplary embodiment, which is connected to the openings 17 and 18 in adjacent heat exchanger plates 2 , so that the channels 5 are separated from one another for different media are. (Fig. 4)
