Description
Title: A heating panel The present invention relates to a heating panel, comprising a frame in which a heating module is positioned, the heating module comprising a rigid, plate -like, electrically insulating carrier provided with a CNT (Carbon Nano Tube) coating comprising carbon nano tubes on the carrier, an electrical connection in contact with the CNT coating to apply a voltage over the CNT coating, the panel further comprising a back plate, an insulation plate, and a ceramic front plate. In addition, the present invention also relates to a building provided with means for heating the interior of the building.
Conventional heating in the home works by warming up the air around someone; for instance a radiator does most of its heating through convection currents (it also gives off small amounts of infrared radiation). When the radiator warms up, it heats the air directly around it, which then expands and rises. As the hot air rises, it creates a vacuum behind it, which pulls colder air into contact with the radiator, causing it to heat up. As the hot air begins to cool down it drops down back to floor level. This cold air gets heated again and this process keeps repeating itself — this is known as convection heating.
Most conventional heating systems do emit some infrared waves. Infrared heating is an addition to the domestic and commercial heating scene. It is emitted from the heater, which then travels unimpeded through the air until it hits an object. The object absorbs the radiation, causing molecules within it to vibrate, producing heat.
If the waves come into contact with humans, they will travel into the body providing a feeling of deep heat, but even if a person is not directly in the way of the waves, any solid body will vibrate when the waves hit them, causing them to radiate heat back towards that person.
A benefit of using electric infrared panels in the home, is that there is no need to integrate any pipe work or fuel storage facilities when installing the panels. There are also no direct emissions associated with using the electrical panels and by using them in conjunction with solar panels there is 100% emission free heating. In addition electric infrared panels can be placed high up on the walls or the ceiling, so they will be easy to keep away from pets and children. Infrared heating thus works by heating the surface area of a room, rather than the volume (as is the case the traditional convection heaters), which means they are heating considerably less to provide the same amount of heat.
Electric infrared panels also only take a short time to reach full operating temperature and therefore are much more efficient at heating a space than conventional space heating heaters. The heat is also contained in the thermal mass of the room surfaces, as opposed to the heat. This means that it stays warmer for longer and draughts do not play as large a part when compared with convection heaters.
In addition, conventional heaters warm the room by convection currents that circulate dust particles continuously around the home, however these convection currents do not occur with infrared heating, so for people who suffer from asthma, infrared panels can be the ideal solution.
Such infrared heating module is known from International application WO2017213495. That document discloses a heating element, comprising a rigid, plate like, electrically insulating carrier having a low thermal expansion coefficient in a predetermined temperature range, a CNT coating on the carrier, comprising carbon nano tubes, and an electrical connection in contact with the CNT coating to apply a voltage over the CNT coating. The electrical connection comprises at least one electrically conductive, elongate member in the form of a strip of copper paint, applied on and extending over the CNT coating.
In addition, KR20120032080 teaches a portable cooling and heating device wherein a CNT discharge plate is provided to prevent unnecessary power consumption by cooling and heating only desired spaces. Such a portable cooling and heating device using a CNT discharge plate comprises a base panel, a case, a discharge unit, and a power supply unit. The power supply unit is installed in one side of the inner top end of the case and supplies power to the discharge unit.
US 2016/001632 relates to automotive sheet heater comprising: a stacked structure of a far-infrared radiating layer, a metal layer, a metal wire-containing carbon nanotube heating layer, and an electrode layer, which is electrically connected to the carbon nanotube heating layer and induces heat emission of the carbon nanotube heating layer when power is applied thereto, wherein the far-infrared radiating layer emits radiant heat due to heat emission of the carbon nanotube heating layer.
CN 207569971 relates to a graphene heat dissipation floor, comprising a substrate, a nano carbon film heating layer and an upper panel from bottom to top, wherein in the middle of the nano carbon film heating layer and the upper panel a metal thermal conductive layer is arranged, wherein the upper panel is provided with aplurality of blind heat dissipation holes along the thickness direction, and the opening of the blind heat dissipation holes is downward.
CN 108912119 relates to a graphene infrared heating plate comprising a base, a heat insulation layer, a far-infrared reflective layer, a graphene heating layer, a heat dissipation layer, and a heat gathering layer.
WO2009079890 relates to a nano far-infrared carbon crystal electric room heater comprising a heating unit, a radiating unit and a heat-conducting insulating layer, wherein the heat-conducting insulating layer and the radiating unit are installed in one side of the heating unit and a thermal insulating layer and a rear cover plate are installed in the other side of the heating unit. The radiating unit includes a base plate and some aluminum radiating fins located on the base plate, and the thermal insulating layer includes an insulating thermal insulating layer and a far-infrared reflective thermal insulating layer, wherein a metal frame can be added to the periphery of the electric room heater.
An aspect of the existing infrared heating panel is the maximization of the radiant heat output. The input energy is electricity and that electricity is transferred to radiant heat.
Another aspect of the existing infrared heating panel is that the panel as such is fragile. This means that the panel is prone to breakage, scratches and damage, which will reduce the user's enjoyment. And the construction of the existing infrared heating panels is that they cannot withstand water vapor, i.e. the panels are not splash- proofed.
An object of the present invention is to provide a far infrared flat plate heating panel that maximizes the radiant heat output.
Another object of the present invention is to provide a far infrared flat plate heating panel that is resistant to mechanical shocks and possible damage.
Another object of the present invention is to provide a far infrared flat plate heating panel that can be used in wet rooms, such as bath rooms.
Another object of the present invention is to provide a far infrared flat plate heating panel that maximizes its far infrared radiation in a uniform way across the surface of the panel.
The present invention thus relates to a heating panel, comprising a frame in which a heating module is positioned, said heating module comprising a rigid, plate- like, electrically insulating carrier provided with a CNT coating comprising carbon nano tubes on said carrier, an electrical connection in contact with the CNT coating to apply a voltage over the CNT coating, said panel further comprising a back plate, an insulation plate, and a ceramic front plate, wherein the heating module is positioned between the ceramic front plate and the insulation plate, characterized in that between the ceramic front plate and the insulation plate a heat distribution plate is positioned.
On basis of such a heating panel one or more objects are achieved.
The present inventor found that the presence of such a heat distribution plate ensures a uniform distribution of heat thereby spreading the radiant heat at the edges of the front plate smoothly and hence maximizing the far infrared equality.
The present inventor found lower temperatures at the edges of the front plate of an infrared heat panel than at the center part of the front plate of an infrared heat panel.
This disadvantage has been successfully eliminated by the insert of the present heat distribution plate between the ceramic front plate and the insulation plate.
The present heat distribution plate is a plate that is in close contact with the heating module.
During operation of the heating panel, the present heat distribution plate warms up and ensures a better temperature distribution over the entire front panel of the heating panel.
An essential property of the material used for the present heat distribution plate is the heat conductivity.
In addition, the material itself should be dimensional stable when manufacturing the heating panel.
Examples of suitable materials for the present heat distribution plate are chosen from the group aluminum, brass, bronze, copper, gold and silver and its alloys.
A preferred embodiment of a heat distribution plate is an aluminum foil having a thickness in a range of 0,1 mm - 5 mm.

The function of the insulation plate is to prevent the build-up of heat at the back plate.
In an embodiment of the present heating panel an elastic strip is provided between the frame and the ceramic front plate. The presence of such an elastic strip provides a close fit of the ceramic front plate and the frame itself.
In an embodiment of the present heating panel an elastic strip is also provided between the insulation plate and the back plate. The presence of such an elastic strip provides a close fit of the insulation plate and the back plate in the frame itself.
