Definitions

  • the invention relates to a device for heating hot water, consisting of a hot water tank and a heat exchanger arranged in the hot water tank, which has at least one coil with a plurality of windings for a heating medium, which extends in a surface that extends over the bottom of the hot water tank lie.
  • E Ring area are bent in spiral turns.
  • the flow channels which are formed between the sheet metal walls and are connected in parallel in terms of flow technology therefore lie one above the other, which, in connection with the vertical flow paths for the liquid to be heated, which results between the individual turns of the sheet metal walls, supports a vertical flow of this liquid and thus, in the case of hot water heating, the desired Stratification of the process water destroyed.
  • due to the height of the heat exchanger, which is determined from the multilayered flow channels it is not possible to use the storage volume of the domestic hot water storage tank as the usable volume.
  • the process water in the area of the upper flow channels for the heating medium is already at a higher temperature, so that the heat transfer from the heating medium to the process water is impaired in this area.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a device for heating domestic water of the type described in such a way that essentially the entire storage volume of the domestic water storage is available as the usable volume and good heat transfer from the heating medium to the Industrial water is ensured.
  • the invention achieves the object in that the windings of the pipe coil, which are distributed at least substantially over the entire floor surface and preferably form a spiral, form only one winding layer in height.
  • the overall height of the heat exchanger can be restricted essentially to the cross-sectional dimensions of the tube forming the coil, so that with an arrangement of the heat exchanger immediately above the bottom of the domestic hot water tank, the usable volume essentially corresponds to the storage volume of the domestic hot water tank.
  • the heat exchanger can always lie in the area of the cold water in a surface extending over the bottom of the domestic water storage tank.
  • the turns of the pipe coil distributed over the bottom surface also enable a more uniform process water heating over the cross-section of the process water storage compared to helically coiled pipe coils, which in turn results in an optimal stratification of the process water within the process water store.
  • windings of the pipe coil Since it is important to arrange the windings of the pipe coil in a single layer in a surface that extends over the floor, it is not absolutely necessary to lay these windings in the form of a spiral, although particularly simple constructional conditions result from spiral-shaped laying, especially with regard to set for a uniform winding distribution over the floor area.
  • the area formed by the coils of the coil does not need to be a cross-sectional plane parallel to the ground.
  • the spiral from the individual coil windings could also lie on a flat cone surface for better emptying.
  • the pipe coil can be formed from a pipe constricted with respect to its cross section from two opposite sides and laid upright.
  • This "dragonfly-like" cross-sectional shape increases the heat exchange surface in relation to the volume of the heating medium and, due to the edgewise arrangement of these tubes, requires a water flow between the tube turns which is advantageous for heat transfer.
  • the laying of the pipe coil in the form of a spiral can lead to undesirable displacements of the individual turns against one another due to thermal expansion or external influences.
  • the turns of the spiral pipe coil can be held in a holder with star-shaped holder arms, which can be connected directly to the process water tank, for example by welding.
  • the subject matter of the invention is shown in the drawing, for example. 1 shows a device according to the invention for heating domestic water in a cross section through the domestic hot water tank, and FIG. 2 shows this device in a section along the line II-II of FIG. 1.
  • the device for heating used water shown essentially consists of a used water tank 1, which is only shown in the floor area for reasons of clarity, and a heat exchanger 2 arranged in this used water tank, which is arranged directly above the bottom 4 of the used water tank 1 connected to an emptying line 3.
  • This heat exchanger 2 is formed by a tube coil 5 which is laid in several windings 6 in the form of a single-layer spiral which lies in a cross-sectional plane extending over the base 4.
  • These turns 6 are received by a holder 7, which consists of star-shaped holding arms 8, in which slots 9 are provided for receiving the individual turns 6.
  • the slots 9 which are open on one side for inserting the windings 6 are closed by webs 10 connected to the holding arms 8, so that the windings 6 are fixed radially immovably in the holder 7.
  • the pipe coil 5 was produced from an initially round pipe, which was compressed in the area of the windings 6 from opposite sides in order to obtain a dragonfly-like cross-sectional shape, as can be seen in particular in FIG. 2.
  • This cross-sectional shape of the coil 5 not only brings about a simpler bending of the spiral because of the upright orientation, but also leads to a considerably more favorable heat transfer, because first the cross-sectional area is reduced compared to the cross-sectional circumference and between the individual turns 6 advantageous flow channels for this result in warming water which flows via a cold water line 11 into the domestic water storage tank 1, which opens above a baffle plate 12 covering the drain line 3.
  • FIG. 1 As can be seen in FIG.
  • the invention is of course not limited to the illustrated embodiment.
  • the windings 6 of the coil 5 would not have to lie in a cross-sectional plane, but could also be laid along a flat conical surface in order to ensure independent ventilation upwards, although the risk of air accumulation in the apex region of the tube also with horizontal ver ⁇ is low.
  • the spiral could have multiple threads.

Abstract

Un dispositif de chauffage d'eau sanitaire comprend un réservoir (1) d'eau sanitaire et un échangeur de chaleur (2) monté dans le réservoir (1) d'eau sanitaire (1). L'échangeur de chaleur (2) comprend au moins un serpentin (5) à spires multiples qui contient le milieu de chauffage. Les spires du serpentin (5) se situent dans une surface qui s'étend au-dessus du fond (4) du réservoir (1) d'eau sanitaire. Afin d'assurer des conditions avantageuses d'échauffement, les spires (6) du serpentin (5), qui forment de préférence une spirale et qui sont distribuées au moins pratiquement sur toute la surface du fond du réservoir, ne forment qu'une seule couche dans le sens vertical.
