Definitions
- the invention relates to a radiator for space heating with extruded Profiles made of aluminum and its alloys according to the preamble of claim 1.
- Each upper connection piece is screwed in on both sides upper screw sleeve with left-right thread formed by the lower horizontal member facing end of the associated vertical member is rotatable here.
- the lower connection piece of each vertical link is in contrast from a screw sleeve screwed into this with a unidirectional Thread formed, the projecting head of the lower horizontal link clamped against the vertical link.
- radiators according to this prior art have the particular disadvantage on that at each junction of the connecting piece between the Vertical links and the upper and lower horizontal link threads both can be cut into the vertical links as well as the horizontal links must, which are essential for bracing the individual parts.
- FR A-2298076 which forms the closest prior art, describes the modular construction of a radiator using annular seals to seal the connection between the finned tubes and the cross-pieces as well as the use of tie rods to ensure the cohesion of those to be connected Elements.
- annular sealing elements are not suitable for sealing elongated profile cross-sections of vertical and horizontal profiles with different flow cross-sections.
- the present invention is therefore based on the object of a radiator to create the type of radiant heat improved, i.e. high surface temperatures equal to the heating medium on the entire radiation surface, its manufacture and Assembly is very simple and its outer surfaces before assembly are surface treated.
- An advantageous embodiment of the invention is characterized by the features of claim 2 reached.
- FIG.1 is a section of a single-row radiator shown, which consists of a number of vertical members 1.
- the Vertical members 1 are essentially of the same width and each have a radiator exactly the same length.
- the vertical members 1 consist of an extruded profile Made of aluminum or a light metal alloy with over their entire Length of constant dimensions.
- the vertical member 1 has at least one in its interior Wall of the vertical member formed heating channel 2, which is preferably is separated by a web 3 (Fig. 3) into two equal channel parts.
- the channel parts form an elongated cross section and are semicircular Rounding on both sides.
- a recess 4 is provided, which is of the same shape on the other end face Projection 5 is arranged opposite.
- ribs 7 serve on the one hand the vertical stability of the vertical members 1 and on the other hand as a secondary heating surface.
- a Horizontal member 8 arranged, which is provided with a horizontal channel 9 is.
- In the area of the vertical heating channels 2 of the respective lined up Vertical links 1 are 8 vertical channels 10 in the horizontal link introduced that a connection between the horizontal channel 9 and the Form heating channels 2.
- At the respective contact surfaces of the horizontal link 8 and the vertical members 1 are seals 11 with through openings 12 arranged partially in the vertical channel 10 and partially plug in heating channel 2 and adapted to the shape of channels 2 and 10 are.
- each seal 11 Approximately in the middle of each seal 11 is a collar 13 as an assembly aid and additional sealing surface between each profile tube member 1 and the Profile body 8 provided.
- the horizontal member 8 has on its vertical members 1 facing Side with a recess 14 extending in the axial direction a front wall 15 and a rear wall 16.
- the recess 14 is designed to match the thickness of the body of the vertical links 1 and overlaps it in such a way that sufficient clamping bracket of the horizontal member 8 is ensured.
- the recess 14 is arranged so that the drawing lower openings of the vertical channels 10 in the middle of their groove bottom come to lie.
- the horizontal link is made by means of a pin connection 18 8 with the aid of the seals 11 with the number of vertical links 1 attached to the respective end faces.
- a free cut 19 of the ribs 7 ensures that the rear wall 16 the recess 14 is exposed along the horizontal member 8 (see FIG. 3).
- the seals have 11 has a number of through holes 12, from seal to seal have different diameters.
- Standard fittings and sealing plugs are used to complete the radiators to the provided as flow or return for the heating medium Connections on the horizontal member 8 provided by appropriate Threaded connections are attached.
- Such constructed radiators offer in terms of their application several positive effects, such as the high proportion of radiant heat in the total amount of heat given off by the radiator, the high thermodynamic Efficiency through the uniform surface temperature, as well as a high flexibility of the radiators in terms of architecture favorable design and execution.
- the high Heat radiation share very cheap solutions, for example for find targeted heating of workplaces, bathrooms, stairwells.
