Definitions

  • the invention relates to a heat exchanger, preferably made of plastic, which can be used in particular for heat exchange between gaseous media and which has flow channels separated from one another by plates, the flow channels of the primary side and the secondary side alternatingly following one another.
  • Heat exchangers of this type - especially in the plastic version - are being used more and more frequently to save energy. They are primarily used to utilize the heat content of gases emerging from a technological process, which is primarily air. A special area of application is, for example, air conditioning technology, in which the heat content of the exiting, used air is often used to preheat the fresh air.
  • a heat exchanger of the type mentioned at the outset is described, for example, in US Pat. No. 3,847,211.
  • This heat exchanger is formed by corrugated plastic plates arranged between horizontal plastic plates, the flow channels formed between the plates forming the primary and secondary channels.
  • a disadvantage of this solution is that the essential parts of this heat exchanger can only be produced economically by vacuum forming.
  • the possibility of selecting the materials or plastics that are suitable for the present purpose is very limited, since only a few plastics are suitable for vacuum forming, although they would be suitable for the present purpose, namely as a material for heat exchangers.
  • pressing the parts or heat exchanger elements requires too much material and is also extremely time-consuming, since the corresponding manufacturing processes work too slowly.
  • a disadvantage of the known heat exchanger is that it has too high an air resistance.
  • the known plastic heat exchangers also have the disadvantage that they cannot be disassembled, or only with difficulty. In addition, they usually have flow channels with a small cross section, so that they clog quickly. The latter is particularly favored by the ability of the plastics to charge themselves electrostatically. If a heat exchanger cannot be disassembled, it is very difficult to clean it afterwards. However, if the heat exchanger is not cleaned from time to time, the efficiency of heat transfer deteriorates.
  • the aim of the invention is therefore to eliminate the disadvantages of the heat exchangers mentioned and to create a heat exchanger which can be mass-produced at low cost, can be assembled into units of any size and can be dismantled at any time.
  • the invention is also intended to enable the plastic that corresponds optimally to the temperature occurring to be used for any purpose.
  • the heat exchangers according to the invention should also be able to be used to assemble heat exchanger systems which meet the requirements for size and capacity.
  • the invention accordingly relates to a heat exchanger which has flow channels which are separated from one another by plates, the flow channels of the primary side and the secondary side alternatingly following one another.
  • the primary-side and / or the secondary-side flow channels at least the side separating an entire primary and secondary channels (forming a coherent surface) and the sides determining the height of the flow channel are formed by an element which is extruded or pressed as one piece or at least three of the outer sides of each second flow channel, that is to say all primary-side or all secondary-side flow channels, consist of an integrally extruded plastic part or pressed metal part.
  • the heat exchanger element is made of plastic in the width of an entire flow channel in one piece.
  • the manufacturing-technical advantages of this type of production do not require any explicit explanations.
  • the elements formed in the manner described can be assembled by simply assembling the heat exchangers in accordance with the required or desired size.
  • the heat exchanger according to the invention can be dismantled by simply lifting off the elements, can then be cleaned and then easily reassembled.
  • the invention further enables that - if the requirements change - the heat exchanger can be adapted to the new conditions without difficulty by enlarging or reducing its contact areas.
  • both the primary-side and the secondary-side flow channels are formed by elements of identical design arranged one above the other.
  • Another solution can of course also be advantageous, for example if only all primary channels or only all secondary channels are formed by an element delimited on four sides, extruded or pressed over its entire width from one piece, and the flow channels between these channels are formed by the mentioned elements and spacers are formed.
  • the elements forming the flow channels are simply placed one above the other and arranged in a corresponding box, as a result of which a finished heat exchanger is produced without the use of binding elements. This can be broken down into its elements for cleaning, then cleaned and reassembled after cleaning.
  • This embodiment of the invention has a one-piece extruded or pressed elements forming the flow channels in bundles and holding them in position, separating the input and output sides of the primary-side and secondary-side flow channels, on the box for the primary side and for the secondary side. and outlet openings are provided.
  • the heat exchanger according to the invention can also be equipped with a housing which accommodates the bundle of several superimposed elements, the primary and secondary sides of the individual bundles being separated from one another and mixing spaces being formed between the primary and the secondary sides.
  • three sides of the primary and the secondary flow channels that is to say the side 3 separating the flow channels and the two sides 4 determining the height of the flow channels, are formed by an integrally extruded plastic element 5 .
  • These elements 5 are stacked on top of one another and, accordingly, form the heat exchanger shown in FIG. 2.
  • the arrows P indicate the course of the primary-side flow channels 1 of the heat exchanger, while the arrows S indicate the course of the secondary-side flow channels, which here form a right angle with the primary-side flow channels.
  • the elements 5 shown in FIG. 1 are essentially plates which have a smooth surface 3 and a surface 4 provided with projecting ribs, which run parallel and at a distance from one another.
  • Such an element 5 is produced in a simple manner, for example, in that the plastic mass rolled into a strand is passed through calender rolls, one of which has a smooth surface and the other has a surface which has several evenly on its circumference has spaced axially parallel grooves.
  • the profile strand thus embossed with ribs running transversely to the rolling direction is then cut to length in accordance with the desired element size and the plates or elements 5 thus obtained are installed in accordance with the arrangement shown in FIGS. 1 and 2.
  • the element 5 has only two ribs spaced apart from one another.
  • the invention is a heat exchanger in which plates are arranged at a distance from one another and stacked parallel one above the other, between which flow channels provided for a primary medium or a secondary medium are used in a sequence that varies from one space to another are, wherein the plates are designed as one-piece extruded or pressed parts 5, which have a smooth surface and a surface with parallel spaced projecting ribs.
  • the plates 5 designed in this way are stacked to form flow channels in such a way that the free ends of the ribs come to lie sealingly on the smooth surface of the following plate.
  • the successive plates can be stacked on top of one another in such a way that the flow channels of successive plates run transversely to one another, that is to say form acute angles to one another.
  • the spacers 7 are expediently produced in the same way by extrusion as the elements 6 and then simply cut to length. 4, 5 and 6 show different possibilities for the cross section of the individual elements of the heat exchanger.
  • the elements forming the heat exchanger are provided with surface-enlarging ribs 15 which are extruded together with the element in order to increase the heat transfer.
  • FIG. 8 shows a basic circuit of the heat exchanger according to the invention, in which the heat exchange takes place in cross flow.
  • the direction of flow of the medium introduced on the primary side is indicated by the arrows P and the direction of flow of the medium flowing on the secondary side is indicated by the arrows S.
  • a heat exchanger which essentially consists of three stacked plate packs, which are constructed so that the medium entering on the primary side according to the arrow P straight - in the drawing (see Fig. 9) from right to left - flows through the three plate packs 25, 26, 27.
  • the medium flowing in on the secondary side, the direction of flow of which is indicated by the arrow S on the other hand, first enters the plate pack 27 in a cross-flow to the primary-side medium, then passes in counterflow through the plate pack 26 and cross-flows to the primary side entering medium from the disk package 25 again.
  • the heat exchanger which can be seen in principle from FIG. 9 can also be composed of the elements 5 which can be seen from FIG. 10. A particularly good heat transfer between the two media is achieved by this flow guidance.
  • one of the elements 5 forming the heat exchanger is designed in such a way that the ribs 24 forming the flow channels become continuously shorter in the direction of the longitudinal sides of the element 5 and 5 end walls 20 on the two end faces of the element 5 are formed, which have the same height as the ribs 24.
  • entry and exit take place from the side, offset by 90 ° to the flow into the Flow channels of the other element, the inlet and outlet of the media being separated.
  • the flow paths of the medium flowing in on the primary side are identified here, for example, by the arrows P 1 (inlet) and P2 (outlet) and by the arrows S 11 S 11 (inlet) and S 2 , S 22 (outlet).
  • the extruded plastic elements 5 are accommodated in the manner shown in FIG. 11 as a bundle 17 in a housing 8 designed as a box. Due to the special design of the housing 8 according to the invention, the bundle 17 is centered in its position and at the same time fixed. In addition, due to the special position of the bundle 17 in the housing 8, the inlet and outlet openings of Primary and secondary side separated. An inlet opening 11 and an outlet opening 12 for the primary side as well as an inlet opening 13 and an outlet opening 14 for the secondary side are provided in the wall of the housing.
  • This embodiment enables a particularly compact design of the heat exchanger according to the invention.
  • the elements of the bundle 17 can be taken apart, cleaned in a simple manner and then reinserted into the housing 8.
  • the housing 8 is of course closed from above by means of a cover, not shown.
  • FIG. 12 An embodiment is shown in FIG. 12, in which a bundle 17 is arranged in a housing 16 in the form of plates 17 which are to be viewed as plate stacks and are arranged in the form of plates which are spaced apart from one another and stacked parallel to one another in such a way that mixing spaces 18 are formed between the primary sides and between the secondary sides. These mixing rooms enable an even heat transfer.
  • the flow paths of the media entering on the primary side and of the media entering on the secondary side are identified by arrows P and S, respectively.
  • the heat exchanger according to the invention can be produced both from plastic and from metal very simply and economically in inexpensive mass production.
  • the heat exchangers according to the invention can easily be put together on site by assembling the elements made in appropriate dimensions.
  • the wall thickness can be kept small, which brings significant thermal and economic advantages. Because it is easy to assemble, the prerequisites for regular cleaning and maintenance are given, and the exchanger surface can be enlarged depending on the requirements or be reduced.
  • the individual units can also be assembled into units of any size. These can be removed at any time, can be easily cleaned and reassembled, and there is also the option of subsequently increasing or reducing the heat transfer area according to the respective requirements.
