Definitions

  • Panel heater for heating a room comprising an inlay of thermal resistant and electric insulating material, mainly to be used as a distance holder.
  • a heater for heating a room, with electric heating element is defined by the preamble of patent claim 1.
  • the temperature will vary rapidly upon connecting and disconnecting the heating element, and the heater will be chilled rapidly when disconnected, for example in a saving interval.
  • the main object of the invention is therefore to create a heater having a surface temperature as even as possible, on contact surfaces. Another object is to increase the average surface temperature, and thereby providing higher efficiency for a given heater dimension.
  • a particular object is to reduce or convert noise generated in the beater, so that it does not bother users.
  • Figure 1 shows a vertical cross section of a heater according to the invention
  • Figure 2 shows a plan view of the heater in Figure 1.
  • a heater with a plate formed heating element 11 which may be manufactured by on known techniques.
  • the heating element 11 is encapsulated in a housing 13 comprising a front cover 14, a back cover 15 with a cooling element 16 that is fastened to the wall with two carrying brackets 12 with known shape.
  • the heating element 11 may in principle have a any known shape.
  • it may be made of glass with a layer that may function as a resistance element This offers the advantage of a higher heating capacity and better capability to emit heat during disconnection. This may be a features of interest in some areas with capacity problems in the power system.
  • the front cover 14 has the shape of a low rectangular bowl with corrugations 17 shaped as corrugated iron, with tops and bottoms stretching vertically, as the depth of the bottoms may be about 3-7 mm.
  • the low side edges 18 stretching all around this element, are designed for joining the back cover 15.
  • the back cover 15 in the example has a corresponding rectangular bowl form like the front cover, but without corrugations.
  • the back cover 15 has an even surface, and is provided with side edges 19 fitting with the side edges 18 of the front cover 14, so that they may be locked together with screws (not shown) or squeezed, welded or adhered permanently together.
  • the cooling element 16 is provided with large corrugations increasing the surface area for this part. This part is outside the contact area, and may therefore have higher surface temperature.
  • the heating element 11 is placed on an inlay 20 shaped as a plate or mat of mineral wool, preferably glass wool, that entirely covers the front of the heating element 11, and covers a narrow area at the upper and lower edge of the back side of the heating element In this way, the heating element 11 is fastened in mineral wool. It will not be necessary with distance holders to hold the heating element in place, as the mineral wool inlay 20 will give sufficient firm and lasting support. Most of the back side of the heating element will be open to thermal radiation towards the back cover 15, and extra transfer of heat to the cooling element 16.
  • the inlay of mineral wool in the front has proven to result in strong evening out of the temperature across the front panel 14. This provides a better temperature distribution and means that the average temperature of the front cover 14 can be closer to the maximum surface temperature.
  • the heating element 11 is preferably placed on glass wool or ceramic "wool", which is electrically insulating and not hygroscopic.
  • the inlay 20 may be compressed from a relatively loose glass wool mat, or made as a compressed mat from the manufacturer. Eventually, synthetic fibre material may be used with sufficient thermal resistance and electrical insulating properties, and composite materials with corresponding structure and material characteristics.
  • the inlay 20 may be completely plate formed, or provided with perforations, or have the shape of a grid with holes. It is not necessary to be continuous between the heating element and the front, as long as it is close to the front panel, and provides for evening out of the temperature on this.
  • An alternative to the illustrated beating element may be a heating element based on steel bars with cooler flanges, for example of aluminium or another metallic, generally plate formed element.
