Abstract
An optically transparent electrically heated convection heater for use as a space heater in homes, offices, shops. Typically, said convection heater consists of a transparent layer 1 upon which is deposited a layer of a transparent electrically conductive material 2 such as indium-tin-oxide, electrodes 3 and 3a are formed on opposite edges of the transparent electrically conductive layer 2 and electrical wires 4 and 4a are connected to the electrodes. The transparent electrically conductive layer 2 is sandwiched between layer 1 and another transparent layer 1a. The passage of an electrical current through the optically transparent conductive layer 2 causes it to be heated according to the Joule effect, thereby heating the transparent panels 1 and 1a and the surrounding air by convection.
Description
2361990 Transparent Electric Convection Heater This invention relates to
an electrically heated optically transparent convection heater for use as a space heater.
Space heaters in the form of electrically heated radiators and convection heaters are well known and find application in the domestic environment as well as in offices, shops and the like.
Existing electrically heated radiators are predominately of the oil filled variety and typically consist of a hollow metal fin filled with oil attached to a tube containing a heating element. When an electrical current is passed through the heating element it is heated according to the Joule effect and subsequently heats the oil in the fin. Convection currents within the oil then cause the oil to move within the fin distributing the heat throughout the fin. Existing electrically heated convection heaters typically consists of a metallic-wire heating-element suspended within an otherwise hollow metal case. The top and bottom of the case are open to the air so that air has a free passage through the case and over the element. When an electrical current is passed through the heating element it is heated according to the Joule effect and thence heats the surrounding air, which removes the heat to its surroundings by convection. Such examples of the prior art are opaque and consequentially have diminished aesthetic appeal.
An object of the present invention is to provide an optically transparent electrically heated convection heater for use as a space heater in homes, offices, shops and the like, comprising a transparent layer made of glass, temperature-resistant transparent rigid or flexible plastic or the like which has been coated on one or on both sides with an optically transparent electrically conductive material, for example but not limited to, Indium-Tin-Oxide.
A second object of the present invention is to provide a space heater in the form of an optically transparent, electrically heated convection heater with increased aesthetic appeal over existing electrically heated opaque radiators and convection heaters.
A third object of the present invention is to provide a generic optical display platform for use as a basis for optical effects and/or displays, for use in homes, shops, offices and the like for aesthetic, entertainment, promotional, advertisement and similar purposes.
According to the present invention there is provided an optically transparent electrically heated convection heater for use as a space heater in homes, offices, shops and the like.
The essence of the present invention is a heating element made from an optically transparent, electrically conductive material, for example but not limited to, Indium-Tin-Oxide. The optically transparent, electrically conductive material is formed upon one or both sides of a transparent substrate such as glass, temperature-resistant transparent rigid or flexible plastic or the like and is heated according to the Joule effect by the passage of an electrical current. The substrate carrying the optically transparent, electrically conductive material is then formed into 2 a convection heater suitable for use in homes, offices, shops and the like by attachment to a further sheet or sheets of glass, temperatureresistant transparent rigid or flexible plastic or the like and/or a suitable supporting structure and/or mounting.
According to the second aspect of the present invention there is provided an optically transparent electrically heated convection heater made of glass, temperature-resistant transparent rigid or flexible plastic or the like with provision for either wall or floor mounting which may be illuminated with coloured lamps, light-emitting diodes and the like to provide optical effects and/or displays, for use in homes, shops, offices and the like for aesthetic, entertainment, promotional, advertisement and similar purposes.
According to the third aspect of the present invention there is provided an optically transparent electrically heated convection heater made of glass, temperature-resistant transparent rigid or flexible plastic or the like with provision for either wall or floor mounting which may be decorated with pictures, company logos, trade marks, coats of arms, other graphic designs and the like to provide optical effects and/or displays, for use in homes, shops, offices and the like for aesthetic, entertainment, promotional, advertisement and similar purposes.
In the preferred embodiments of the present invention the present invention will be operated by connection to the mains electricity supply. As this may present a potential safety hazard in the preferred embodiments access to the heating element or elements, the mains wiring and all electrodes electrically connected to the mains wiring will be restricted. This can be achieved by one or more of the following non- restrictive exemplary methods: attaching the transparent conductive layer complete with its substrate to a sheet of glass or temperature-resistant transparent plastic or the like such that the transparent conductive layer is sandwiched between its substrate and the glass or temperatureresistant transparent plastic or the like, where the substrate can be glass, temperature-resistant transparent plastic or the like; sandwiching the transparent conductive layer complete with its substrate between a layer of glass or temperature-resistant transparent plastic or the like and another layer of glass or temperatureresistant transparent plastic or the like; providing a margin around the edge of the sheet of glass, transparent plastic or the like which is free of the transparent conductive layerl bonding of the glass and or temperature-resistant transparent plastic or the like sheet or sheets to each other so as to preclude access to the transparent conductive layer; placing of the sheet of glass, transparent plastic or the like coated with the transparent conductive layer upon or adjacent to an electrically insulating surface such that access to the transparent conductive layer is restricted; or any combination of the above thereof The power dissipated by a single electrically conductive layer, for example a transparent conductive layer, may be formulated in accordance with Equation I as follows:
V2 H P = - - (1) Rsh L where P is the power dissipated in the film; V is the supply voltage; R,h is the sheet resistance of the film in Q/square; 3 H is the height of the film as defined in Figure 1; L is the length of the film as defined in Figure 1.
Equation I can be transposed and used to calculate the sheet resistance of the transparent conductive layer required for any given power-supply voltage and dimensions of the said layer.
For example, a transparent conductive film designed to dissipate I kW of dimensions H = 0.5m and L = I in, connected to an electricity supply with V=240V, would have R,h = 28Q/square. Such a sheet resistance is well within the bounds of sheet resistivities that can be obtained by such processes as DC sputtering, DC magnetron sputtering, RF sputtering, RF magnetron sputtering, evaporation, spray coating, dipping and the like; for indium-tin-oxide films and other transparent conductive films and any of the aforementioned processes or others can be used to apply the transparent conductive film to the substrate layer.
In practicing the present invention the power dissipation per square metre of surface area (the power dissipation density) of the convection heater will be adjusted such that the ultimate surface temperature of the convection heater will be in the approximate temperature range 50'C to I OO'C with a preferred temperature of typically, though not exclusively, 70'C. Operating the convection heater in the above temperature range ensures that a significant proportion of the heat is removed from the convection heater by convection rather than by radiation. The surface temperature of the convection heater will be a function of the thermal conductivity of the material from which the panels that constitute the body of the convection heater are made and consequently the said surface temperature will be dependent on the material from which the said panels are made. The preferred power dissipation density is approximately, though not limited to, I kWM-2.

A first embodiment of the present invention will now be described by way of a non-restrictive example with reference to Figure 2. Layer 1, made of glass or of a temperature-resistant 4 transparent plastic or the like, is coated with transparent conductive layer, for example but not limited to indium-tin-oxide, on one side only leaving a margin around the edge of the layer I uncoated. The margin is of sufficient width to allow the layers I and I a to be bonded together and prevent the transparent conductive layer 2 from being accessed from the edge. Electrodes 3 and 3a made from a metallic material such as, but not limited to, copper, tin, gold or the like are placed upon opposite edges of the transparent conductive layer so that they make a low resistance electrical contact to the transparent conductive layer. Layer I a, of the same dimensions as layer 1, is left uncoated. Layer I a is assembled adjacent to layer I such that the transparent conductive layer 2 on layer I is sandwiched between layers I and Ia. Electrical wires 4 and 4a make contact with the electrodes 3 and 3a to allow an electrical current to pass into and out of the transparent conductive layer. An electrical current is passed through the film, which heats it according to the Joule effect, and the power dissipated by the film is formulated by Equation 1.
