Definitions

  • the invention relates to a plate heat exchanger for heat-exchanging media in separate Circuits, consisting of stacked and soldered individual heat exchanger plates, the form a package that is vertical of connections for the inlet and outlet flow channels for the heating or cooling medium and is interspersed with flow channels for other media, which are mutually exclusive are separated and from which the heating or cooling medium and the others Spread media in separate horizontal channels, which preferably alternate.
  • a plate heat exchanger of this type is known, for example, from WO 94/29659, IPC F28D 9/00, known. With this plate heat exchanger there are only two separate circuits, one for water and one intended for oil.
  • the adapter element is connected to a mounting plate.
  • the Adapter element which has a connecting channel, the oil by appropriate positioning and / or the design of the adapter element can be routed to any location.
  • the Adapter element can also accommodate a pressure relief valve, which with a corresponding differential pressure of the oil connects the upstream side to the downstream side.
  • the adapter element of the described Plate heat exchanger consists of a thick plate in which the connection channel is incorporated. This is disadvantageous in terms of weight and cost for the plate heat exchanger.
  • the plate heat exchanger unsuitable for more than two media involved in heat exchange.
  • their media such as retarder oil, hydraulic oil and gear oil, require cooling.
  • To the heat exchanger described is not suitable or intended. Often in such In cases where several individual heat exchangers are designed and installed. In addition to higher costs also the disadvantage that a larger space is required.
  • Figures 12 to 16 of GB-A-2 052 722 show a liquid-liquid plate heat exchanger and described, with which also three different liquids, water, gear oil and engine oil, can be subjected to heat exchange.
  • 17 to 20 occurs fourth heat exchange medium is added, which is cooling air through a part of the heat exchanger flows.
  • the cooling air is not a medium that circulates through the plate heat exchanger becomes. Therefore, there are no flow channels for the cooling air that break through the heat exchanger plates intended.
  • 21 shows a further exemplary embodiment, in which a total of five Media are involved in heat exchange. One of them is the cooling air again.
  • the one shown there and The plate heat exchanger described has a separating plate approximately in the middle, so that the flow channels not the entire stack of heat exchanger plates for the liquid cooling or heating medium break through.
  • the cooling air through sections of both heat exchanger parts flows.
  • the separating plate dividing the entire heat exchanger which is usually quite stable, leads to higher weight and higher costs.
  • the object of the invention is that Plate heat exchanger from the generic term so that it can be divided into two parts without are suitable for heat exchange between more than three circulating media and requires a smaller total number of openings in the heat exchanger plates, which makes manufacturing technology advantages and improve reliability.
  • the plate heat exchanger then has, in addition to the flow channels for the cooling or heating medium three further separate flow channels for other media.
  • the separation of the flow channels takes place in that in the flow channels for the first heat-exchanging Medium a partition, which is preferably designed as a partition, is used is soldered and completely blocks these flow channels.
  • a partition which is preferably designed as a partition, is used is soldered and completely blocks these flow channels.
  • the flow channel for that third heat-exchanging medium is therefore due to the smaller diameter of the tubular Flow element that used in the flow channel for the first heat exchanging medium is formed between these two parts, which are arranged coaxially to one another. Further is the flow channel via the side connection channel of the adapter element with the inlet or outlet Outlet connected to the third heat exchange medium.
  • the size of the individual sections of the heat exchanger for the heat exchanging media will by positioning the various separators in connection with the formation of the Flow element, in particular determines its length protruding into the flow channel, the is carried out as required for the respective application with regard to the desired cooling capacity, etc. is.
  • the flow channels for the cooling or heating medium penetrate the entire heat exchanger and are in fluidic connection with the horizontal channels, which are in contact with the horizontal Alternate channels for the other media.
  • the supply or discharge of the cooling or heating medium is from one side as well as from the other side of the plate heat exchanger possible. Again, the decision for one or the other the other variant depends on the operating conditions. For this are on the plate heat exchanger make no changes themselves, except that the connecting flanges and the other Closing plates blocking the flow channel side can be exchanged.
  • the plate heat exchanger according to the invention for the total heat exchange at least four media is suitable, only four openings are required in the heat exchanger plates, whereby the number of connection points causing leaks compared to the status of the Technology has been significantly reduced. Furthermore, there are essentially only two types of heat exchanger plates necessary.
  • the plate heat exchanger according to the invention is also characterized by its compact size Construction and its versatile use wherever cooling or heat exchange of several media to be kept separately in a confined space.
  • a retarder oil-water heat exchanger is shown. It should be sent ahead are that Fig. 1 is not a scale section through Fig. 2. Like the comparison of these two figures to the person skilled in the art is the middle part of the plate heat exchanger 1 in FIG. 2 shown approximately to scale. The middle part was shown in Fig. 1 very shortened to the essential Highlight parts.
  • the plate heat exchanger 1 of the exemplary embodiment according to FIG. 1 consists of 26 stacked one inside the other Heat exchanger plates 2a; 2b, which are identical in their outer dimensions. Both forms of heat exchanger plates 2a: 2b have only four openings 29, around which the flow channels 3 forming openings 29 for the cooling or heating medium A, in this case cooling water, one each Collar 30 is formed. that on the heat exchanger plate 2a upwards and on the heat exchanger plate 2b is directed downwards. so that the collar 30 form a suitable soldering edge.
  • the heat exchanger plates 2a; 2b otherwise differ in that the other two. the flow channels 4 forming openings 29.
  • connection of the heat exchanger plates is very good 2a; 2b around the flow channel 3, likewise with inserted annular disks 28, as for the flow channel 4 could be carried out without departing from the main ideas of the invention.
  • the same thing applies if you have the flow channel 4 as the flow channel 3 in the peripheral connection area want to train.
  • the flow channel 4 serves the medium B, in this case retarder oil.
  • the cutting disc 17 in the flow channel 4 is in the embodiment between the fourth and fifth heat exchanger plate 2a; 2b, counted from below. This cutting disc 17 separates one from the flow channel 4 lower flow channel 5, which is provided for the medium C, in this case gear oil.
