Definitions

  • the invention concerns a heat exchanger tube package especially intended for domestic central heating installations.
  • the tubes of the heat-exchanging package are fitted in the sieve bottoms by welding. Because the sieve bottom is an element exposed to increased pressure and high temperature, it has to satisfy strict requirements. The point of connection between the sieve wall and the tube often loses its tightness or gets deformed during the welding process. Moreover, it frequently happens that the sieves burn through because they are insufficiently cooled. In addition, the sieve must be appropriately thick which increases its cost.
  • a heat exchanger tube package in which the tubes are arranged parallel to one another is characterised in that at least some of the tubes are bulged at one of their ends, where the rim of the bulged end of the tube is in a shape other than circular, and where the tubes are arranged within the package according to a pre-set pattern and the rims of the ends of all tubes on both sides of the package are permanently connected to one another.
  • the rim of the bulged end of the tube in a package is in the shape of a regular hexagon or equilateral triangle or square with concave sides, or its shape is convex and concave.
  • the rims of the tube ends are connected to one another with a weld.
  • the solution according to the invention makes it possible to eliminate sieve walls from a heat exchanger package.
  • the bulged ends of the tubes are connected to one another by melting their rims and welding them together directly, which results in a durable, very strong, and tight connection.
  • An embodiment of the heat exchanger tube package 1 incorporates the tubes 2 arranged parallel to one another, as shown in Fig. 1 .
  • the tubes 2 are bulged at their both ends, and the rim 2a of the bulged end of the tube 2 is in a shape other than circular.
  • the tubes 2 are arranged in the package 1 according to the pre-set pattern and their rims 2a are connected permanently to one another, for example by way of welding.
  • the rim 2a of the bulged end of each of the tubes 2 of the package 1 is in the shape of a regular hexagon, as shown in Fig. 2a, Fig 2b .
  • the package arrangement follows the pattern of a honeycomb, as shown in Fig. 2 .
  • the rim 2a of the bulged end of each tube 2 of the package 1 is in the shape of an equilateral triangle, as shown in Fig. 3a, Fig. 3b .
  • the two versions of arrangement of the tubes 2 in the package 1 are shown in Fig. 3 i Fig. 4 .
  • the rim 2a of the bulged end of each tube 2 of the package 1 is in the shape of a square, as shown in Fig 5a, Fig.5b .
  • the two versions of arrangement of the tubes 2 in the package 1 are shown in Fig. 5 and Fig. 6 .
  • the rim 2a of the bulged end of each tube 2 of the package 1 is in the concave and convex shape.
  • the two versions of the shape of the rim 2a of the tubes 2 shown in Fig. 7a, Fig. 7b and in Fig. 8a, Fig. 8b , and the pattern of their arrangement in the package 1 are shown in Fig. 7 and Fig. 8 , accordingly.
  • the rim 2a of the bulged end of some of the tubes 2 in the package is in the shape of a square with concave sides, as shown in Fig. 9a , Fig. 9b , while ends of some of the tubes 2 are not bulged.
  • the tubes are arranged following the pattern shown in Fig. 9 . In between the tubes with bulged ends there are tubes with no bulging at their ends.
