Definitions

  • the invention relates to a heat exchanger, in particular for a gas-fired boiler manufactured by casting with a lost shape, according to the preamble of claim 1.
  • Generic heat exchangers made of aluminum materials are used in boilers for used the heat exchange between the hot gases and the boiler water.
  • she consist of at least one heating medium flow channel with at least two delimiting walls, wherein at least one wall a Schugasbermult, preferably provided with surface enlarging elements wall side, as well as a water-wetted Has wall side.
  • center member In an enclosed by end members center member are the Projections arranged on both sides. They each extend evenly over the entire area on one side.
  • the invention is based on the object, the design of a heat exchanger especially to optimize that casting with a lost shape even with smaller ones Quantities with reasonable effort is possible.
  • the heat exchanger is characterized by an intermediate member with a longitudinal axis mirror-symmetrical design and / or arrangement of the projections on both sides.
  • the design and / or arrangement of the projections on both sides in each case approximately divided along the longitudinal axis in two halves.
  • the heights of the projections on the two differ by the longitudinal axis divided halves in rows. This will alternate those between them standing front ends of the protrusions resulting column, so are in rows shifted to one or the other boiler member out.
  • the heights of the projections can on the two divided by the longitudinal axis halves also by combining distinguish several identically designed rows. There are always two or more adjacent rows are the same height. In addition, it is possible that the heights of the projections (3) are each designed differently in each row, with each individual or blockwise adjacent projections (3) have different heights.
  • An inventive heat exchanger consists of several cast Kesselgliedem 1, 1 '.
  • each boiler member 1, 1 ' is in each case at least one heating medium flowed through Channel 2, the flow of hot gases around the channel wall surface enlarging Has projections 3.
  • the projections 3 are arranged on both sides. Not shown are end members, which delimit the hot gas flues of the middle links 1, 1 'on both sides.
  • Each central element 1,1 ' has a mirror-symmetrical design to the longitudinal axis and / or arrangement of the projections 3 on both sides.
  • the design and / or arrangement of the projections 3 on both sides in each case approximately along the longitudinal axis split into two halves.
  • At the separation point now access two associated Center members 1, 1 'and their projections 3 into each other, because the heights of the projections 3 on the two halves of a heat exchanger surface divided by the longitudinal axis differ.
  • FIGS. 2 to 4 show that same model halves of preferably with lost Mold cast central link 1, 1 'are produced.
  • 5 Wasserleitrippen and webs 6 are removed to breakthroughs 7, connections 8 or the corresponding contours of the heating medium flowed channel. 2 train. Only here do the differences arise between a right or left half of the model according to FIGS. 2 and 4.
