Definitions

  • the invention relates to a heat exchanger, in particular for swimming pools, comprising a substantially cylindrical housing, which is flowed through substantially axially by a first medium, wherein the housing has at its axial end faces connections for connection to adjacent line sections for the first medium, while a second Medium flows through two separate radially extending to the housing connections a laid in the housing and designed as a helix line whose helical axis is parallel to or identical to the housing axis, wherein the helical line for the second medium consists of a corrugated tube, extending in the radial direction end portions which are connected and fixed to the separate terminals for the second medium, and wherein the separate terminals for the second medium extend from the outside while traversing the housing to the inside of the housing.
  • Such swimming pool heat exchangers are used to heat the bath water as the first medium by means of a heating water as the second medium, wherein the ratio of the volume flows of bathing water and heating water is of the order of about 5 to 1. Accordingly, the bath water flows through the heat exchanger in the axial direction and in this case flows around the Edelwassertechnisch, which is laid to increase the heat exchange surfaces helically in the heat exchanger housing.
  • a cylindrical displacement body is usually arranged within the helix, which directs the bathing water flow around the heating water line.
  • Such heat exchanger designs are also known for other applications and so z. B. also in fuel coolers, as in the DE-A 34 40 060 is disclosed.
  • a major problem in mounting the heat exchanger is that the helical pipe must be welded from the inside, so under very tight conditions against a housing opening in alignment with the on the outside radially extending separate terminals.
  • the helical heating water line is just as stainless as the housing;
  • the components are also made of titanium.
  • the design with helical pipe and with a usually additionally arranged within the coil displacement body inevitably leads to a relatively large volume of construction with a correspondingly large weight, this large volume due to the high quality materials consistently used also correspondingly large production costs.
  • the present invention seeks to provide a heat exchanger, in particular for swimming pools available, which is characterized by a simplified mounting and cheaper manufacturability.
  • This object is achieved in that the extending in the radial direction end portions of the corrugated hose corrugated and connected inside the housing to said separate connections for the second medium via a plug connection and fixed there in the region of their corrugations.
  • the main advantage of the inward routing of the connection between the corrugated hose coil and the separate connections for the second medium is that the corrugated hose can be fixed by simple plug-in mounting on these inwardly projecting separate terminals, without the need for a welded connection or a similarly complicated connection method What would be in the cramped installation space inside the housing would be very difficult or would accomplish only an additional division of the housing.
  • the end portions of the corrugated hose are inserted into the separate connections for the second medium and fixed there, for example, by pins which engage positively in troughs of the corrugated hose.
  • the determination of the corrugated hose in the separate terminals on other fixing means such as form-fitting the corrugated hose acting on staples, locking or clamping elements and the like is possible, as long as they meet the demands and requirements, as they exist in the present exemplary application of a swimming pool heat exchanger.
  • the separate connections for the second medium are formed separately from the housing and inserted through the housing openings, so that during assembly of the heat exchanger first given the corrugated hose coil in the housing and only then separate connections are inserted from the outside into the radial housing openings and finally the plug connection between corrugated hose and separate terminals when inserting the separate terminals is made in the housing.
  • the corrugated hose can be fixed by the said fixing pins on the separate connections.
  • various embodiments are conceivable, such as a screw connection.
  • This plug-in assembly can against withdrawal of the separate connections from the housing - similar to the case of the corrugated hose connector - are secured by fixing means in the form of fixing pins on the inside of the housing act on the separate connections and this form-fitting on the housing wall set by the fixing pins on create the housing inner wall.
  • the said and demanded rotation of the separate terminals relative to the housing can be achieved in a simple manner by a hexagonal shape, by knurling, polygonal or other polygonal shape, wherein the separate terminal may have a shoulder or a collar in said hexagonal shape, while the Housing opening should have at least in some areas this form-fitting collar.
  • a sealing element in the overlapping area between corrugated hose and separate connection which can most easily consist of at least one O-ring which is attached to the associated corrugated hose end section is positively engages in at least one wave trough and with its the radial portion of the separate Occurs for the second medium acting on the outside of the inside of the radial portion.
  • Said radial sections of the separate connections for the second medium are expediently made smooth cylindrical in order to produce the required tight connection with the sealing element (that is, preferably the O-ring).
  • At least one of the corrugated tube end sections can cooperate with a different fixing means than the fixation pin, in particular in the case of larger pressure differences between the first and second medium.
  • This fixing means can produce a latching connection, for example, by a barb-like configuration.
  • Another fixing means may be formed in that, in addition to the sealing element, it is plugged onto the corrugated hose and inserted together with it into the separate connection, wherein the fixing means should be dimensioned in its diameter relative to the diameter of the separate connection in such a way that it is prestressed the inside of which rests, wherein the fixing means beyond should also engage positively in the corrugated tube.
  • the corrugated tube end portion may consist of a corrugated tube formed by simply cutting to length.
  • the corrugated hose end section is calibrated by stretching and somewhat reduced in its flexibility so as not to give way when compressed in the separate connection by upsetting in the axial direction.
  • spacers are provided between the corrugated hose coil and the inner surface of the casing jacket, through which the first medium, in particular the swimming pool water, can also flow through this gap region between the housing and the corrugated hose.
  • the spacers should be designed so that they favor the aforementioned plug-in assembly.
  • the spacers mentioned have the further advantage that the corrugated hose is supported by them in order to be able to prevent flow-induced noise emissions.
  • it can be recommended not only to improve the flow around, but also to prevent flow-induced noise, one or more Anström emotions in the form of baffles in the housing and the corrugated hose coil to use.
  • a particular advantage of the simplified mounting of the heat exchanger according to the invention and also the fact that the separate connections are not integrally connected to the housing, but are formed separately from this, is that only responsible for the heat exchange surfaces, so the corrugated hose from Stainless steel must be made, while the housing may consist of corrosion-resistant plastic, which can reduce the cost of the heat exchanger according to the invention again drastically.
  • the helical line had to be welded to the housing in the region of the radial openings and brought into connection with the radial ports, so that also a weldable corrosion-resistant material, ie in particular stainless steel was required for the housing.
  • connection of corrugated hose and separate connection can be made by plug-in assembly and without welding; And if you wanted to make the separate connection also made of stainless steel, so could still consist of the entire plastic housing and still allow a significant cost reduction.
  • the first medium usually consists of the swimming pool water, while the second medium is formed by the heating medium or the heating water.
  • the present heat exchanger can also be used for cooling fluids, with the second medium then having to have a temperature reduced relative to the fluid temperature.
  • the heat exchanger for other media combinations, for example for domestic water heating in gas heating, fuel cells and the like, for waste heat recovery and more generally for a variety of industrial applications, in the automotive sector, etc. - just where usually heat exchangers Cooling or heating coil design can be used.
  • the present subject invention has the advantage that in a heat exchanger housing, the front side only have connections for a medium due to the required volume flow rate, the second medium is guided via radial ports in the heat exchanger and there can be transported over a corrugated hose coil with maximum length and thus maximum responsible for the heat exchange surface. That is, there are no transition areas such as manifolds or the like required to make the connection between the corrugated hose and arranged on the outside of the housing connections and usually due abprupter changes in the flow direction, a large pressure drop and because of their own not beendanziehiehenden for heat length cause a reduced heat exchanger performance.
  • results in the subject invention in which the corrugated tube merges directly into the separate connections for the second medium, in comparison with heat exchanger designs of comparable dimensions, a significantly reduced pressure loss or improved heat exchanger performance.
  • the omission of welding of the metallic components with respect to the connection of the corrugated hose to the separate connections to apply a simplistic connection technique, and with respect to the connection between the heat exchanger housing and the separate terminals to be able to produce both objects made of different materials, so that now the Housing may consist of inexpensive plastic.
