Definitions

  • the invention relates to a radiator with two vertical, mutually parallel pipes, which can be connected at the lower end to a fixed flow or return and are connected to each other by a plurality of horizontal, also parallel pipes, the interior of which in the openings formed in the welded tubes are connected to the interior of the vertical tubes.
  • Such radiators are known. They have the horizontal, straight pipes welded directly to the front of the vertical pipes.
  • This known construction has the disadvantage that the heat exchanger surface of the radiator can only be increased at a certain distance of the vertical pipes, which is predetermined in particular by the distance of the fixed flow and return, that the radiator overall has a greater height and thus receives more horizontal pipes. If the straight, horizontal pipes were to be extended beyond their fastening point with the vertical pipes, there would be no circulation in the projecting pipe areas and therefore no significant heat exchange.
  • the heat exchange surface can be adapted to the respective requirements without the number of these horizontal pipes or the length of the vertical pipes, i.e. the height of the radiator must be increased.
  • Due to the C-shaped design of the horizontal pipes there is the possibility of arranging the pipe bends at a more or less large distance from one another, which increases the length of the pipe center piece and thus the heat exchange surface of the radiator. Since the pipes with their ends behind the pipe bends are connected to the vertical pipes, regardless of their length, there is always a circulation through the full pipe length, which is why the horizontal pipes always participate in heat exchange over their entire length.
  • the vertical tubes can be connected to one another by a panel-like covering which at least partially covers the space between the tubes.
  • a panel-like covering which at least partially covers the space between the tubes.
  • a cladding which is preferably also made of metal, increases the heat exchanger area heated by heat conduction from the heating medium.
  • the connections and valves of the radiator can be covered with such a covering.
  • this panel-like cladding represents a further element for the optical variation of the radiator according to the invention.
  • FIGS. 1 and 2 the end pieces 3a of the horizontal pipes 3 are connected to the rear of the vertical pipes 1 and 2. This makes it possible to make this connection by means of cross-hole pressure welding, which can be produced particularly easily and with high reliability.
  • FIG. 4 shows that the end pieces 3a can of course also be connected to the front of the tubes 1 and 2 and that it can be advantageous to cover the lower part of the vertically extending tubes 1 and 2 containing the connections by a covering 4 which is simply placed on the vertical tubes 1 and 2.
  • the vertical tubes 1 and 2 are provided over their entire length with a panel-like covering 5, which in turn is placed on the front of the tubes 1 and 2 and optionally welded to them or connected in some other suitable manner.
  • This panel-like covering 5 increases the surface participating in the heat exchange. Since the panel 5 is heated by heat conduction, not only an optical change of the radiator, but an increase in its heat output is possible in this way.
  • FIGS. 5 to 8 show four further design options for radiators according to the invention.
  • the difference between the radiators according to FIGS. 5 and 6 lies in the length of the horizontal pipes 3; in the exemplary embodiment according to FIG. 7, a total of three groups of pipes 3 of the same length are arranged, which are at different distances from one another.
  • FIG. 8 shows an embodiment with two groups of horizontal tubes 3. While the tubes 3 are of the same length within one group, the length of the tubes 3 in the two groups is different.
  • FIGS. 9 to 12 also show other possible embodiments.
  • the radiator according to Figure 9 has the largest possible heat exchange area; 10 uses tubes 3 with three different tube lengths, which are arranged at a constant distance from one another.
  • FIGS. 11 and 12 show that the pipes 3 can not only be designed in groups with different lengths, from which it can also be seen that the use of pipes 3 of different lengths can greatly change the appearance of the radiators.
