Definitions

  • the invention relates to a hot water tank according to the preamble of the main claim.
  • Such hot water storage tanks are generally known and are placed either vertically or horizontally with respect to their longitudinal axis.
  • the heat for heating the process water is provided by a built-in heat exchanger in the tank space in the form of a helical pipe that forms the flow channel for the heat-supplying medium, the supply and return connections being led out of the tank.
  • a venting of the heat exchanger of the type mentioned at the outset would also not be possible with a horizontal arrangement of the container, since gas or air bubbles would catch in the upper regions of the passages of the heat exchanger or the coil.
  • the same applies to vertically arranged containers with regard to the temperature stratifications mentioned and poor utilization of the volume with regard to the application of heat to the usable volume available per se.
  • the invention is therefore based on the object to improve a hot water tank of the type mentioned with regard to the arrangement and design of its heat exchanger and to ensure that on the one hand the usable volume is used as optimally as possible while avoiding temperature stratification and this is associated with the requirement that there is no possibility in the heat exchanger for dirt accumulation and for catching gas bubbles.
  • the lower region of the reservoir is fully used for accommodating the heat exchanger, the basket shape being adapted to the radius of the container. Temperature stratifications do not occur in this configuration, since the heat exchanger seen in the projection covers and covers practically the entire horizontal and central cross-sectional area of the container. Since the pipe forming the coil and preferably also the supply and return connection pieces have a continuous gradient, no dirt can accumulate, and free ventilation to the top is also readily possible.
  • a cylindrical helical spiral region can additionally be arranged above the spiral, also with the proviso that there is a slope at each point of such a basket-like spiral.
  • This embodiment is preferred, and advantageously in connection with a specially designed cold water inlet connection in the sense of sub-claim 5, which ensures a wide-area distribution of the incoming cold water with respect to the basket-like heat exchanger.
  • a cold water supply can of course also be provided when the container is arranged horizontally.
  • the enclosure is only indicated by dashed lines, and it can be seen that the heat exchanger 1 is housed in the lower half 2 of the container 4 horizontally oriented with its longitudinal axis 3, the individual strands 5 of the helix 6 at least with respect to the cylindrical wall 7 of the container 4, the course of which is adapted, and thus the helix 6 is tapered and arranged to be approximately basket-shaped from top to bottom.
  • the short parts of the strands 5, which can be seen in FIG. 2 could also be shaped in such a way that they likewise extend into the region of the container end bottoms 7 'and run in an adapted manner to them. Seen in projection (see arrow 10 in FIG. 2), the heat exchanger thus covers almost the entire central cross-sectional area 14, as a result of which any temperature stratification is largely avoided.
  • FIGS. 1, 2 the whole, including the coil 6 forming tube train the supply / return connection piece 8, 9 are designed to run continuously with a slope, which on the one hand prevents the accumulation of dirt and on the other hand allows perfect ventilation upwards.
  • the supply and return connection pieces 8, 9 are arranged on the same side of the container 4, which is considered to be advantageous for a possible stacked arrangement of such hot water storage tanks and the associated connection assembly.
  • FIG. 3 shows a vertically standing container designed according to the same principle.
  • the basket-like course of the tube train of the helix 6, i.e., following the imaginary circumferential surface course of a flat truncated cone or a flat curved shell, is indicated by dashed lines in Fig. 3 with the lowest possible assignment to the bottom 7 'of the container 4.
  • the projection surface as seen in the direction of the arrow 10, is almost completely covered by the heat exchanger 1.
  • a further cylindrical helical course connection of the gears 5 is preferred of the pipe pull above the bottom spiral, as shown in solid lines in Fig. 3, with the proviso that the gears 5 have a slope at every point.
  • the cold water inlet connection stub is advantageous and also within the meaning of the stipulation of avoiding temperature stratification.
  • Fig. 4 provided in its container-side end with an upwardly shielded manifold 12 with side openings 13, which thus ensures that the incoming cold water is largely evenly distributed over the entire container cross-section.
  • a distributor connector 12 can also be provided when the container 4 is arranged horizontally according to FIG. 1.
