Definitions

  • the invention relates to panel heaters. More particularly, the invention relates to a panel heater with enhanced safety means.
  • US 4728780 discloses panel heaters which are used as room heaters, disposed on walls, ceiling or floors.
  • the panel heater is incorporated with a heating pipe, an electric heating wire running through it and aluminum granules stuffed between the two. Because spherical aluminum granules are closely packed; the heat conductivity of such panel heater is very good, which minimizes the heat loss and reduces the time to heat up a room.
  • An automatic o ⁇ -off switch is generally provided to control room temperature.
  • panel heaters used as room heaters disposed on wall ceiling or floor. These heaters have electrical heating element incorporated in oil which heats up the panel and the panel radiates heat into surrounding medium.
  • electrical heating element embedded in resindus electrical insulants that are thermally conducive arid embedded in between covered metal or non-metallic panels facing sheets are also made.
  • Such panel heaters when used at heights less than 6'ft from floor level are provided with safety precautions not to cover the panels as this can elevate temperatures and result in fire hazards.
  • IEC 60335-2, and UL 2021 respectively stipulates that when the heater is covered with 25-mm felt, the temperature of such coverings should not exceed 150 deg centigrade, and that when covered with specified materials they should not get ignited glow or emit embers.
  • each of the top front faces and the bottom front faces of the panel are provided with at least one .
  • protrusion extending between 6mm to 25mm by maintaining higher thickness at the protrude portion. Width of the protrusions can be selected as is convenient.
  • Protrusions can be integrally, configured during manufacturing of the panel covering, or could be provided with separate protrusion fixed to panel covering subsequently.
  • the protrusion members can either be configured as a continuous member or can be provided at specific intervals across the length of the top and bottom edge of the panel.
  • the protrusion members can be shaped to add to presentable look of the heater. Further projection at the center of the panel can be added depending on size of panel.
  • Such a construction ensures creation of an air gap between the panel's surface and the covering material, (1) This riot only avoids direct contact but will also provide some heat transfer due to air gap during test for a possible abnormal or erroneous operating.(The gap thus can be fixed relation to surface temperature of panels and allowed raise of temperature of any covering). By adjusting the dimension of the air gap, the temperature of the covering material can be controlled.
  • Figure 1 (a) Shows a prior art single-wall mounting panel heater.
  • Figure 1 (b) Shows a single-wall mounted panel heater according to the Invention.
  • Figure 1 (c) Shows a panel heater with protrusions according to the invention.
  • Figure 1 (d) Shows both sides of a panel heater according to the present invention.
  • a panel heater (B) As shown in figure l(a), a panel heater (B) according to prior art is mounted on a wall (A) via its mounting legs (E). When the heater is covered with material such as felt (C). The covering (C) touches the panel (B), thereby reaching instantaneously with switching on of the heater nearer to the surface temperature of the panel (B). .
  • Fig 1 (b) shows the effect of protrusion members (D) provided at bottom and top according to the invention, which creates air gap between the panel surface (B) and the covering material (C) and the panel (B).
  • the edge projection (D) should be used on both sides of the panel (B) as shown in fig. l(d).
  • This invention is applicable for all panel heaters whether fixed or movable and electrical or oil filled of any material and where a possibility exists for abnormal operation by covering the heater.
  • data of typical experiment shows distinctive advantage of this improved construction with protrusions of 15mm and 20mm.
  • the panel is covered by felt 50% thicker than 25mm specified in test standard to demonstrate its effectiveness.
  • safety can be greatly enhanced against fire hazard, when the surface is covered for any reason where no temperature limit or cut off control is used and- also where such device fails.

Abstract

L'invention porte sur un panneau chauffant doté d'un moyen de sécurité amélioré et pouvant être utilisé comme radiateur, et étant dans ce cas disposé sur les murs ou sur le sol, et incluant : - un panneau chauffant plat (B) rempli d'huile et utilisant l'énergie électrique ou, en variante, un panneau chauffant dans lequel un fil chauffé est recouvert d'un matériau électriquement isolant abrité à l'intérieur d'un panneau de revêtement plat, alimenté en électricité depuis une source classique, et monté sur un mur ou sur un sol ; - pourvu d'au moins une protubérance sur la partie supérieure du panneau, ou, en variante, d'une protubérance sur la partie supérieure et d'une autre sur la partie inférieure, de manière à ce que, lorsque le panneau est recouvert d'étoffe ou de feutre, soit créé un intervalle d'air permettant de diminuer significativement les températures atteintes à la surface du panneau et sur l'étoffe, et ainsi d'améliorer les niveaux de sécurité en matière de prévention du risque d'incendie.
