Definitions

  • the invention relates to radiators, in particular plate, panel or flat radiators, with at least one plate-shaped heating surface and with at least one convector attached to the room and facing it, which has an essentially flat cladding surface.
  • the convector or the convector surface In known flat radiators, it is common for the convector or the convector surface to be arranged on the back of the plate-shaped heating surface or in the case of radiators with a plurality of plate-shaped heating surfaces between them. Because of the particularly favorable power / weight ratio W / kg, the version with a convector surface on each side of a plate-shaped heating surface is particularly cheap. However, since the surface of the plate-shaped heating surface, which is embossed due to the water channels, is in some cases disturbing, radiators with additional strongly structured convector surfaces on the visible side cannot prevail.
  • Retrofitted or factory-fitted cladding especially on the visible side of flat radiators, as also specified in G 87 15 122.7, always leads to a performance reduction of between 3 and 6%. If one also takes into account the additional material weight of the cladding, the performance weight deteriorates many times over.
  • the front or visible side of a plate-shaped heating surface of an embossed flat radiator is clad with a glued-on plate, which also reduces the visible side involved in convective heat transfer through the cladding.
  • a plate arranged on the front side serves in particular to keep the amount of convection heat as low as possible.
  • German utility model 19 72 230 this is achieved by means of a plate heater with a convector, which has a plate that covers the entire front side of the heater and can be detachably attached to it.
  • this does not ensure sufficient heat transfer between the convector and the front panel, because a panel that is only hung up only touches the convector at a few points and is therefore only supplied with heat by insufficient heat conduction.
  • noises can occur at the points of contact between the convector and the front panel.
  • the object of the invention was therefore to improve the heat transfer between the convector and the plate arranged on the front side, in order to heat the air rising in the convection channels not lying against the heating plate better.
  • the panel-shaped cladding surface in the power output of the panel radiator.
  • additional surfaces that are exposed to air and heated by the heating medium are created.
  • the geometric dimensions of the flow channels are chosen so that, given the thermal conductivity of the material, on the one hand enough air can be guided in the flow channels and on the other hand the cooling of the cladding surface still ensures a sufficiently high proportion of radiant heat.
  • the convector surface must have a good heat-conducting connection to the plate-shaped heating surface in order to obtain the smallest possible temperature difference between the convector and the heating surface. This can generally be achieved by a good welded joint.
  • a good connection between the cladding surface and the convector surface is of crucial importance in order to obtain a high convection performance with good steeling performance.
  • this connection is made by an adhesive layer, which remains elastic, particularly after it has hardened.
  • the adhesive layer is advantageously applied over the entire length of the visible surface of the convector.
  • the visible surfaces of the convector are the surfaces of the folded convector sheet that face a viewer and run approximately parallel to the plane of the heating plates.
  • Suitable adhesives are available that can withstand the reduced temperature on the visible surface opposite the heating plate due to the heat being released to the air flowing through it.
  • material which is a good conductor of heat preferably in the form of metallic particles, to the adhesive layer.
  • an adhesive is expediently used which has an increase in volume when it is hardened, as a result of which the manufacturing tolerances of the convector surface are compensated for and between the visible surfaces of the Convector surface and the cladding surface a largely continuous contact is made.
  • the mechanical stability of the two components is also increased by an adhesive bond between the covering surface and the convector. At the same time, the adhesive layer ensures that cracking noises are avoided.
  • the gluing of the cladding surface and the convector also enables the use of materials for the cladding panel that cannot be welded to the convector, which is generally made of sheet steel. As a result, light materials such as. B. aluminum or plastic can be used.
  • z. B. steel sheet for the cladding surface is avoided by the adhesive instead of a weld, the formation of welding spots that appear on the cladding surface.
  • the bonding of the cladding surface and the convector according to the invention can compensate for the manufacturing tolerances that occur in the production of both the heating plate and the convector, the radiator and the convector being produced in an optimized manner only in accordance with thermal requirements. Due to the bonding with an optionally also thicker adhesive layer, the shape of the cladding surface is independent of the shape of the radiator or of the shape of the convector and heating plate. In particular, structured cladding surfaces or converter plates with a low surface quality can also be used.
  • cladding elements for covering the further top, side and bottom surface of the plate heating element can also be attached to the cladding surface. This was previously z. B. not possible during welding because the parts to be welded can no longer be reached or can only be reached with great difficulty with the welding electrodes. Compact units can now be manufactured.
  • the bonding can be done with thermosetting glue before painting, with moisture-curing glue during final assembly, with separately painted or coated individual parts.
  • Mechanical fixation is also required for gluing finished coated components with moisture-curing adhesives with a long curing time.
  • a depression for receiving the adhesive can be formed in the visible surfaces of the convector surface.
  • the cladding surface is preferably essentially flat and deformed only at the edges, in particular for fastening and connecting to other cladding parts.
  • Your surface can be painted and / or designed in a suitable manner decorative.
  • these can be deformed at their edges to such an extent that completely covered radiators are produced by the attachment of side and top covers.
  • the side covers and the top cover can also be molded directly onto the cladding surface.
  • convector surfaces with cladding surfaces are attached on both visible sides.
  • FIG. 1 shows a perspective view of a plate heater 4 with front cladding surfaces 3, 30, rear cladding surface 3, 16, side cladding surfaces 13, 18 and upper cladding surfaces 14, 17.
  • the upper cladding surfaces have openings 15 for the passage of air.
  • the section planes A-A and D-D are also indicated.
  • the plate heater shows a section AA through the upper part of a single-layer plate heater.
  • the plate heater consists of a heating surface 1, which is composed of two half-shells 5. Horizontal water channels 6 and vertical water channels 7 are formed on the half-shells 5.
  • a convector surface 2 is welded onto the heating surface 1, on the visible surfaces 10 of which adhesive layers 9 are applied for bonding to a covering surface 3.
  • the cladding surface 3 has an approximately Z-shaped bend 20 on its upper edge, which is used to fix the cladding surface 3 on the convector surface 2 with a clamp 19.
  • the approximately Z-shaped bend 20 can also be designed as an angle mounted on the cladding surface 3.
  • a section A-A through the lower section of a single-layer plate heater is shown.
  • an approximately U-shaped bend 21 which serves for mechanical fixing in the area of the lower edge of the cladding surface 3.
  • the U-shaped bend 21 can also be designed as a bracket mounted on the cladding surface 3.
  • the cladding surfaces 3 have approximately Z-shaped bends 22 on their lateral edges, onto which lateral covers 18 are attached. If the installation of such a radiator in front of a wall is provided, a preferably flat and only deformed at the edges cladding surface 3 on the side facing the room is sufficient.
  • a chamber (not shown in the drawing) for attachment to the heating plate 1 is provided on the side cover 18 in addition to the bend 22.
  • the second cladding surface 3 which is only indicated by dashed lines, is provided.
  • FIG. 5 shows a section D-D through a two-layer plate heater.
  • the side cover 13 is integrally formed on the cladding surface 30 with an angled portion 131 which extends over the rear heating plate 1. Between the heating plates 1, a supply 8 for heating water is indicated.
  • the cladding surface 30 has an integrally formed upper cover 14 with an angle 141, which extends over the approximately Z-shaped angle 20 of the upper edge of the cladding surface.
  • a bracket 23 is used for mechanical fixation of the Cladding surface 16 opposite the convector surface 2.
  • FIG. 7 shows a detail of a convector surface 2 in a section D-D.
  • a recess 11 for receiving an adhesive layer 9 is formed in the visible surface 10 of the convector surface 2.
  • a gap 12 remains between the visible surface 10 and the cladding surface 3, 16, 30.
