Definitions

  • the invention relates to a standing heat exchanger for the Hot water preparation for pressure washers, being in one essentially cylindrical housing two coaxially one inside the other and a radial one Are arranged at a distance from each other heat exchanger coils, wherein also in the inner heat exchanger coil a downward heating flame which a flow deflection at a lower, below the Heat exchanger coils arranged baffle experiences, and also that Heating gas first flows along the inner heat exchanger and by means of Flow deflection means then flows through the outer heat exchanger, which is then followed by a Chimney escapes.
  • the invention is therefore based on the object, the exchange efficiency to improve such heat exchanger even further.
  • An essential feature of the invention is that in the space between the inner heat exchanger coil and the outer heat exchanger coil one further spiral helical winding is wound, which the gap fills between the inner and outer heat exchanger and / or that in Outside, an oblique winding is wound onto the outer heat exchanger which is the space between the outer heat exchanger and the Fills the housing wall accordingly.
  • the inner helical winding slants has helical gradients at the top, which are optimal Ensure flow guidance, and the residence time of the exhaust gas in the Increase the heat exchanger 4 to 5 times.
  • the inner helical winding the annular space between the Outer circumference of the inner heat exchanger and the inner circumference of the outer Fills the heat exchanger approximately, so that the heating gas does not flow directly upwards can, but is forced to flow upwards on the inclined windings and consequently is diverted through the helical windings.
  • a Double effect achieved because the helical windings serve on the one hand Flow diversion and, on the other hand, are optimal over their entire length flows around from the heating gas. This leads to an optimal one Heat transfer of the heating gas to the diagonal windings around which the water flows.
  • the arrangement of the inclined pipes also ensures that everyone Pipe coils of the inner and outer heat exchangers (which correspond to the state of the Technology belonging coaxially one inside the other) is also optimal from the Heating gases are flowed through. So it comes through alongside optimal guidance the slanted pipes provided also for better guidance of the Heating gases on the inner and outer heat exchangers.
  • the invention is not based on the presence of two such Oblique windings limited.
  • One of the helical windings can also be omitted; for example, only the inner helical winding or only the outer one There is a bias winding.
  • Another essential feature of the invention is that the inner helical winding with the outer diagonal winding via an easy-to-install screw connection connected is. Therefore, easy manufacture can be ensured the two oblique windings do not have to be made in one piece from one another getting produced.
  • the screw connection is preferably designed as an angle screw connection, the one represents very simple connection. This is a major advantage over that State of the art, because so far a screw with hollow screw training as Connection between the inner and outer heat exchanger provided was. Because of this simple screw connection, it is therefore possible to use the inner and the outer helical winding separately and only at the location of Assembly to connect with each other via this screw connection.
  • Such a system can therefore also be easily cleaned because simply loosen the screw connection, the outer helical winding from the inner and can then be separated, for example, the outer Be pulled out, which then the outer jacket of the external heat exchanger is easily accessible.
  • An essential feature of the invention is that the spiral helical winding in Space between the inner coil and the outer Heat exchanger coil for the flow of the water to be heated together are connected. The same applies to those outside on the outside Heat exchanger applied oblique winding, which the space between fills the outer heat exchanger and the housing wall accordingly.
  • the helical windings that exist between the inner and outer Heat exchanger coil or the outer heat exchanger coil and the Housing wall are arranged are designed as structural internals that the perform the same function for heating gas flow as the respective one Heat exchanger coil.
  • These structural fittings are in this case as Sheet metal spiral executed and correspond in their radial and axial geometry approximately in the form of the inner or outer Heat exchanger coil.
  • the structural internals are provided by using square tubes or round materials. Also in the geometries correspond to these embodiments as far as possible Geometries of the above-mentioned oblique windings in tube form. It is about Again, only a few, relatively few windings of coils, each on the inner heat exchanger and wound on the outer heat exchanger are, with respect to a height of a heat exchanger of e.g. 500 mm only 3 to a maximum of 10 helical windings are wound, so that these Windings have a considerable distance from each other.
  • the function this alternatively to the diagonal windings as sheet metal, square or round material trained coils also consists in the efficiency improve and the flow time of the heating gas through the heat exchanger extend.
  • Inner heat exchanger In the interior 24 of the housing there are two coaxially inserted into one another arranged a different diameter heat exchanger.
  • Inner heat exchanger On Inner heat exchanger has inner heating coils 11 that are tight and tight be wrapped next to each other, so that practically only a minimal There is a gap between these heating coils 11.
  • Flame funnel 6 which has an opening, an upper, horizontal wall 27 breaks through.
  • this flame funnel 6 are those for generating the heating flame necessary parts arranged.
  • An inner jacket 3 is at a radial distance from the aforementioned outer jacket 33 provided which forms an annular casing 34 in connection with the outer casing 33, through which the heating gases in the direction of arrow 4 up towards a chimney 25 stream.
  • the two heating coils 11, 12 are connected to one another.
  • At the cold water inlet 20 flows the cold water in the direction of arrow 22 upwards and first enters the inner heat exchanger with the heating coils 11 into it. These turns are connected to the outer heating coils 12 in a liquid-conducting manner.
  • An important feature of the invention is that two different ones Inclined windings 30, 31 are present, which make optimal use of the Ensure heating gases.
  • a series of oblique windings 31 is arranged, which are directed obliquely upwards and thus ensure optimal guidance of the heating gases along these oblique windings.
  • the heating gas is accordingly guided along in the relatively large dimensioned guiding space between the oblique windings and is thus guided spirally along the outer circumference of the inner heating coils 11 and on the other hand along the inner circumference of the outer heating coils 12.
  • the helical windings 31 are arranged in the inner ring gap 15 as far as possible in such a way that they close it as much as possible, so that the heating gases are forced to flow upward along the helical windings 31, so as to ensure a spiral path of the heating gases upwards.
  • the heating gases emerge at the top and are deflected on the underside of the wall 27 and led outward via the chimney 25 in the direction of arrow 26.
  • the heating gases in the direction of the arrow 10 from the baffle 8 after rise above also passed into the outer ring gap 16, where they are connected to the outer Flow out oblique windings 30 obliquely upwards and also on the described, relatively large volume and spirally directed upwards Flow path along the outer periphery of the outer heat exchanger 12 be guided along.
  • the inner helical windings 31 via an elbow 19 with the outer Inclined windings 30 are releasably connected, which generally Advantages described in the description can be achieved.
  • a Hood 28 is arranged in which the corresponding installation parts for the Generation of the flame (ignition device and the like) are arranged.
  • the flame funnel 6 from a burner cylinder 32nd is coaxially surrounded, which is at a radial distance from the flame funnel 6 is arranged and intended to guide the air.
  • the burner cylinder 32 is open on the end face at the bottom.
