Definitions

  • the invention relates to a radiator according to the Preamble of claim 1.
  • Radiators are known from DE-A1-24 40 184, where a number of fluid-filled channels side by side is arranged. These channels are between the two plates or half-shells of a radiator link formed, with the plates between the trained channels abut each other and one Have weld seam around the channels carrying the heating fluid or welded together on the outer circumference are. In the perimeter of that of the two member formed plate-shaped elements is one Welded seam, which prevents the Prevents heating fluids from the radiator sections.
  • a radiator is known from FR-PS 1,394,844, which consists of a plurality of links, in an electric heating element is used in the middle area is.
  • This one-piece plate-shaped Limbs have their height or length a number of openings on the one hand, the convection should improve and on the other hand heat transport from the central heating element to the Limit the size of the slabs to the areas or bridges, that exist between the openings are. In this way, the heat transfer from Radiator interior limited to the circumference of the radiator.
  • the from the turns of the radiator panels formed outer wall offers due to the outside the chosen shape of the turns essentially one smooth surface.
  • the formation of such turns requires a considerable amount of machine Effort and special precautions to the Execute weld seam, which the fluid-filled Space from the turns in the peripheral area of the Link separates.
  • the channel-shaped space of this radiator allows convection of air inside or is intended to form a chimney, in which the air passes from the bottom to the bottom is heated up.
  • This channel is neither below nor closed at the top; that delimit the channel-shaped space Flange parts are in their outer end areas or in the outermost edge area of the respective Radiator link not connected.
  • This and also the radiator according to the invention correspond to the tendency, e.g. B. at room temperature of 25 ° C, a surface temperature of the hottest Zones of the radiator members of e.g. B. 110 ° C to achieve what a (currently specified according to EC standard) Temperature difference of 85 ° C corresponds.
  • the aim of the invention is to provide the same heat output reduce the number of radiator links to be able to get what material savings, acquisition costs lowers and the manipulability of Devices improved in an advantageous manner. Furthermore, the Optics and surface design of such devices improved be without the material consumption or the Increase manufacturing costs.
  • the invention has set itself the goal of on simple, technologically economical, and existing manufacturing processes only marginally changing way, with increased temperature difference working electric radiators with oil filling to create, its manipulability, resemblance and safety in use compared to devices previous design is not reduced, the outside temperature reduced to an acceptable level that has no gaping gaps between adjacent ones Structure shows and has a stable structure.
  • edge zones mentioned in claim 7 are kept free of heating oil, a relatively uniform and low contour temperature of the radiators will be achieved. Furthermore, in the corner or edge positions of the radiators, which are extreme with respect to body contact, particularly favorable, low temperatures can be achieved despite increased heating fluid temperatures.
  • Preferred boundary zone-width ratios for example for mobile 1000 to 3500 watt space heaters, are given in claim 8, wherein, expressed in absolute values, the edge widths for such appliances can have approximately the preferred minimum values.
  • edge zone may be at the bottom running together of the inner and outer weld seam according to claim 9 , which is also the edge zone width is reduced there ,
  • edge zones brings alongside one advantageous stabilization of the rib body in the area from their heat transfer openings the advantage of particularly widened and thus "cooler” Marginal zones in the area of the outer contour edges of the radiator, which have already been mentioned above.
  • the formation or arrangement of a channel in widened edge area causes another on the one hand Reduction of the outer contour temperatures of the Radiators in the operating state, or enables the same Outer contour temperatures higher oil temperatures and thus improved heating performance of the other radiator body zones and on the other hand contributes to the mechanical Solidification of the widened edges of the ribs at.
  • the bottom of the radiator elements associated with the channel extensions of the individual ribs according to claim 11 there protect the lower edge zones of the radiator, which may foot contacts can be made with people. In addition, they also cause further mechanical stiffening.
  • An arrangement is simplifying production of the channel in the vicinity of the external bond zone the edges of the radiator ribs.
  • an opening for heat conduction inhibition in the widened edges or edge zones of the radiator members is provided according to claim 12.
  • An arrangement of the openings mentioned is immediate Accompanying neighborhood to the inner bond zone of the widened edges in terms of heat, strength and production technology, or the location of the openings is particularly advantageous in terms of security.
  • a certain stiffening edge zone can also abandoning the openings, for example in the region of the upper side of the rib edges, bring according to claim. 13
  • a hood is provided on one side, in which, among other things, the temperature control and switching device, the connection for the heating cartridge, the power supply cable with plug and the like are accommodated.
  • These functions can of course be assigned to one or both of the protective hoods according to claim 14 .
