Definitions

  • the invention relates to a heat exchanger composed of a plurality of individual tubes, the individual heat exchanger tubes being connected to one another at their free ends in a liquid-tight and gas-tight manner, keeping flow paths clear, and the outer tube layer being encircled by an edge flange all around.
  • a generic heat exchanger is known from DE 89 15 322.7 U1.
  • the cross-flow heat exchanger described there is constructed from plastic pipe elements, i.e. a plurality of plastic heat exchanger tubes are assembled in such a way that their polygonal end pieces are added in straight rows to form a closed surface. Due to the fact that the middle parts in the addable in rows have the same extent as the cross-sectional area of the end pieces, the middle parts collide tightly in the added tube bundle and form a closed surface. However, since the cross-sectional areas of the central parts are smaller overall than the cross-sectional areas of the end pieces, free spaces remain between adjacent rows of tubes, which add up to spaces through which flow can pass.
  • the heat exchanger tubes of the known prior art can be added to a cross-flow heat exchanger and welded according to the procedure known from EP-A 0 315 052.
  • an edge flange can be attached to the outer pipe layer during the connection process, via which individual heat exchanger elements can be joined together to form a corresponding large element.
  • This edge flange can be welded, glued or cast. This is also an additional step that increases the cost of the end product.
  • the invention is based on the principle of a simple plug connection between pipe ends and connecting elements.
  • the connecting element here is the cover part, which is placed on both free ends of the heat exchanger tubes.
  • This cover part can be made, for example, from polymeric materials by injection molding. Its large number of receiving openings corresponds to the large number of individual tubes to be used for the special heat exchanger structure.
  • These individual tubes can consist of polymer material, but they can also be made of metallic material or inorganic material such as glass etc.
  • the receiving openings of the cover parts are kept up to 15% smaller in diameter than the tube circumference of the plug ends of the heat exchanger tubes.
  • the permissible expansion of the materials used must be taken into account for both the cover parts and the individual heat exchanger tubes.
  • the receiving opening in the cover parts is expanded and the inserted pipe end is compressed.
  • the cover parts are made of polypropylene and the heat exchanger tubes are also made of polypropylene - it can be assumed that the deformation occurs at approximately the same height with both connecting partners.
  • the cover parts are advantageously provided with an insertion bevel in the direction of insertion of the tube ends.
  • a lining made of soft polymer material is introduced into the receiving openings of the cover parts.
  • These special sealing materials can be manufactured in one tool with a single shot using two-component injection molding. With such a structure Deformation work when inserting the pipe ends into the receiving openings while increasing the sealing effect is reduced. The same advantage can be achieved if sealing lips which can be produced in the same way protrude all the way into the receiving openings.
  • the advantage of the heat exchanger according to the invention over those from the prior art is the simple, inexpensive construction by joining the individual parts together by means of a plug connection.
  • the large number of individual heat exchanger tubes can be inserted into the large number of receiving openings in the cover parts by means of an automatic assembly process.
  • the heat exchanger according to the invention can be used for many areas of application. Its use in tumble dryers is just as conceivable as in air conditioning systems for automobiles and other industrial applications, e.g. Flue gas scrubbing, etc. A limitation of the areas of application is not seen.
  • Fig. 1 shows the cover parts 11, 12 of the heat exchanger 1 (Fig. 2).
  • the cover parts 11, 12 are designed symmetrically in this case, so that the description of the cover part 11 can also be read on the cover part 12.
  • a symmetry of the cover parts 11, 12 is not essential to the invention.
  • the cover part 11 is made by injection molding and has a peripheral edge 111, which can be given an elastic seal to seal the connection parts.
  • the cover part 11 is designed in the form of a rectangle with long broad sides 1111, 1112 and shorter narrow sides 1113, 1114.
  • a groove-like shape 1115 is formed on the narrow side 1114 and can be used for connection to further heat exchanger elements.
  • the groove-like shape 1115 can also be formed in a mirror image on the other narrow side 1113 of the cover part 11.
  • the surface of the cover part 11 is littered with dome-like through openings 1116, which are distributed in rows over the surface of the cover part 11.
  • the dome-like feedthrough openings are each self-contained and separated from one another by parts of the cover part 11 that have remained standing, as can be seen from the representation of the back of the cover part 12 in the exploded view shown.
  • the number of dome-like receiving openings 1116 depends on the number of individual heat exchanger tubes 2, which are arranged between the two cover parts 11, 12 in the exploded view shown.
  • the heat exchanger tubes 2 are simple round tubes, which have not been machined at their free ends by sleeves or similar cross-sectional changes.
  • the distance between the dome-like receiving openings 1116 in the cover parts 11, 12 also determines the distance between the individual heat exchanger tubes 2 after the insertion process has been carried out. This distance defines the free spaces between the adjacent rows of heat exchanger tubes, which add up to the cross-flow spaces of the heat exchanger 1. This distance is therefore crucial for the efficiency of the heat exchanger 1.
  • FIG. 2 shows the heat exchanger 1 as it is formed from the individual parts of FIG. 1, namely the two cover parts 11, 12 with the heat exchanger tubes 2.
  • FIG 3 shows various options for the design of the dome-like receiving openings 1116 of the cover parts 11, 12.
  • 3 a shows a detail from the cover part 11 with the receiving opening 1116, into which a soft component made of plastic is inserted.
  • the soft component can have been injected into the receiving opening by means of the two-component injection molding process in the production of the cover part 11.
  • the soft component 1117 can also subsequently introduced into the lumen of the receiving opening 1116 and fixed there, for example by welding, gluing or the like. With its circumferential tip 11171, the soft component reduces the passage cross section of the receiving opening 1116 and thus creates the interference fit for the plug end of the heat exchanger tube 2.
  • Fig. 3 b shows the same structure as Fig. 3 a), but with a different design of the soft component 1117.
  • the soft component 1117 forms the entire boundary 1116 in the illustration shown and thus creates the seal between the cover part 11 and Plug end of the heat exchanger tube 2.
  • FIG. 3 c) shows a structure similar to FIG. 3 a), but without a soft component in the passage area of the receiving opening 1116.
  • the dome-like receiving opening 1116 is delimited by the hard plastic material of the cover part 11. This possibility of construction can also create the gas- and liquid-tight seal between the components end of the heat exchanger tube 2 - dome-shaped receiving openings 1116 of the cover part 11 with a corresponding selection of the materials.
  • FIG. 3 The sealing elements shown in FIG. 3 are only given as examples.
  • the invention also encompasses other cross-sectional shapes which can form the required gas and liquid-tight seals between the components.
