Definitions

  • This invention relates to an electric convection heater in the Preamble of claim 1 mentioned type.
  • Electric convection heaters eliminate the disadvantages of electric ones Radiant heaters that radiate heat directly and tubular or Use helical electrical resistors. Reach radiant heaters high temperatures (> 200 ° C) that cause severe burns to people or nearby materials can catch fire, resulting in fire can have serious consequences; they exhibit great sluggishness in the Heating up the environment on what is disadvantageous for convenience or they are to avoid this, oversized and require higher manufacturing costs and greater power consumption. After all, they require emitting devices complicated and costly form to make maximum use of the heat generated.
  • Electric convection heaters which have a tubular Use resistance that is soldered or welded to a plate.
  • disadvantages in terms of security because along the soldering or Welded joints can cause overheating that is similar to burns or in the case of the electric radiant heaters mentioned above can cause ignition of neighboring materials.
  • comfort disadvantages due to poor heat distribution, with increased Temperatures are generated in the vicinity of the overheated soldering or welding lines, which results in significant radiant heat emission being generated. This leads to excessive drying of the ambient air, especially for people with breathing difficulties is noticeable and disadvantageous.
  • Also arise serious aesthetic disadvantages because near the overheated solder or Welded joints a combustion of floating organisms and Suspended particles caused black discoloration on the walls leads in which these devices are installed themselves.
  • the amount of oil also leads to difficult environmentally friendly disposal, which requires that the oil is emptied and disposed of so that the device is melted down and empty can be processed, with the resulting significant consequences for the logistical and economic measures, for the manufacturer and / or for the Institutions and / or for the user.
  • the invention has for its object an electric convection heater to create the type mentioned, since with a simple and compact structure has fast and uniform heat emission at low operating temperatures.
  • an electrical convection device which by a layered structure is formed, which has a flexible laminar core an electrical resistance circuit is printed, which uniformly over extends the entire extension of the core, the laminar core with the printed resistance circuit with its two side faces over its entire surface is in contact with respective flat heat-conducting plates on the other hand, the respective heat-conducting, profiled heat-conducting plates are welded on or are soldered to the outside, a uniform sequence of vertical Form half waves such that between each of these vertical half waves and the flat plate with which this is welded or soldered, a corresponding vertical Channel is formed, which is open at its upper and lower ends.
  • the applied to the laminar or film-like core or in the form of a printed circuit printed circuit largely covers the entire surface of the flat heat-conducting plates, so that with a compact structure achieves a high heat output even when the heater temperature is low can be.
  • the profiled heat-conducting plates preferably form vertical half-waves polygonal profile (trapezoidal, rectangular, square, triangular ...) or with curved (circular, parabolic) profile. Functionally form the vertical Channels convection air flow paths in which by heating the flat and air currents are generated from the profiled plates.
  • the construction according to the invention combines a great simplicity Number of key benefits, of which the following should be highlighted: the Heating takes place much faster due to the low mass in the Order of magnitude of two minutes; cooling is somewhat slower and takes place in about five minutes, but in any case much faster than oil-based devices, which are around 30 minutes each.
  • the laminar and flexible resistance circuit enables a uniform surface distribution of the heat-generating element and thus the heat generated, so that there are no noticeable temperature differences between different points of the device. It follows that it at this thermal uniformity is not necessary, so high temperatures to achieve as before, whereby you can work below 70 ° C, which is the danger of burns and inflammation continues to decrease, and it results in a Greater comfort because less drying of the ambient air is caused and the heat is distributed more evenly in the room.
  • the convection heater according to the invention results in a large reduction in Volume and weight compared to the previously known convectors what it allows devices with very light weight and greatly reduced size at one great simplicity and economy of construction.
  • Figure 1 is a perspective view showing part of an electrical Convection device according to the invention shows, in which the profiled thermally conductive Plates (3) are trapezoidal polygons. As an additional example, this figure closes Parts of two profiled heat-conducting plates (3), one of which is rectangular Polygons and the other has a curved shape.
  • FIG. 2 shows a plan view on a larger scale and in an orthogonal projection to an electric heater according to the invention, the embodiment according to the Main representation in Figure 1 corresponds.
  • This figure 2 contains a detail that a vertical cross section along the median plane of the opposite vertical channels (5) corresponds.
  • an electrical shown in the drawing Convection device assigns, as this from the perspective view of Figure 1 is recognizable, a construction in the manner of a laminate, which has a flexible Laminar or film-like core (1) on which an electrical Resistor circuit is printed, which is uniform across the entire Extension of the core extends, the laminar core (1) with the printed Resistor circuit with its two side faces over its entire surface electrically insulated, but good thermal conductivity with respective flat heat-conducting Plates (2) is in contact, on the other hand on the respective profiled thermally conductive Plates (3) are soldered or welded on, which are uniform towards the outside Form a series of vertical half-waves (4) such that between each of these vertical Half waves and the flat plate (2) with which it is soldered or welded corresponding vertical channel (5) is formed, the upper and lower Ends is open.
  • this new type of convector is very simple, both in terms of its components and its overall assembly ( Figures 1 and 2). Its functionality is both simple and effective: the heat-conducting ones profiled plates (3), which are soldered to the heat-conducting flat plates (2) or are welded, form vertical channels (5) through the vertical half-waves (4) through which the convection flow of the air heated by these plates (2, 3) is caused, this heating uniform due to the design of the printed circuit on the flexible laminar core (1) and its complete Contact with the flat heat-conducting plates (2) is caused.
  • these heat-conducting profiled plates (3) form vertical Half waves (4) with a polygonal profile; in Figure 1 are two examples, viz trapezoidal and square or rectangular, shown. In the same way you can these profiled heat-conducting plates (3) with vertical half-waves (4) Form curved profile, the figure (1) shows an example in this regard.
  • These profiled plates (3) can be seen in particular from FIG Only via relatively narrow connection areas with the flat plates (2) be thermally connected.
  • connection of the flat and the profiled heat-conducting plates (2, 3) for Formation of the vertical channels (5) can be by welding or soldering or by other good heat-conducting connection techniques are used.
  • These plates (2, 3) are preferably made of good heat-conducting metal, but can also consist of other well thermally conductive materials are known to those skilled in the art are.
