Definitions

  • This invention refers to a manufactrance process for heating panels, as well as the panels obtained from the implementation of said process, contributing basic novel characteristics and important advantages compared with systems known and used in the current state of the art.
  • the invention develops a process to obtain a heating panel from a board based on an insulating and fireproof material, over which a series of components are applied, such as various strips of a conducting material, an insulating material such as glass fiber over the former for its protection and electrical insulation and one or more electroconducting paint films, heat generator, applied throughout prviously determined areas or sectors of the board.
  • a second optional board equal to the first, applied over the mentioned components, determines the formation of a heating panel constructed in a sandwich form.
  • the field of application of this invention obviously includes the industry dedicated to the manufacture of heating components and, especially, heating panels.
  • U.S. Patent No. 5.391.861 describes a heater comprising an electrically insulating board in which two transversally separate electrically conducting strips have been incorporated and connected by means of plurality of longitudinally separated resistors, these constituting the generating heat elements when they are electrically fed.
  • British Patent No. GB-1 354 703 describes a method and device for producing of electrically conducting coatings intended for to provide a coating on a wall by using an electrically conducting coating material expended between electrodes attached to the wall.
  • French Patent No. FR-2 484 180 describe a radiating heating device which includes an active surface in a radiant panel, whose active surface has been arranged in a sandwich manner between a reflecting layer formed by the forward face of a rear panel and a radiant frontal panel, said active surface being obtained by means of a homogeneous layer formed with a material deposited in flowing state, as a painting manner.
  • This invention proposes as the main purpose the development of a process for constructing a heating panel that may be executed simply and rapidly, and by means of which, as the end product, a panel is obtained, which is light, manageable, of reasonable cost and especially guarantees the user an electrical insulation permitting its handling, installation and operation without any risk of electric discharge.
  • the characteristics distinguishing said process basically consist of the arrangement of a base board made of an insulating material like, for example, micanite, in a further layer a coating that is a good electricity conductor, for example, one based on copper, forming longitudinal strips, after which in the following stage a coating material is applied to protect and insulate said strips, of an insulating material, like, for example, one based on glass fiber or a similar material, applying it at least over the areas surrounding the mentioned conducting strips; then, in the following stage, an electroconducting paint is applied on different previously determined surface areas and on the strips of conducting material and the areas of insulating material covering the former, in electrical contact with the conducting strips; the last stage of panel construction consists of the arrangement of a second base board of insulating and fireproof material, preferably of the same material as the former, attached to its face over which the coatings have been made, which it hides or houses sandwichwise, to protect them against any manipulation or external agent.
  • the obtained panel therefore has some sectors coated with electroconducting paint, transmitters of heat when an electric current is made circulate through the same, due to the characteristic of electrical resistance of said paint, joined near the end of the respective conducting strips (of copper), through which a supply voltage of a predetermined level is applied, preferably from the mains, said sectors advantageously consisting of superficial parts, generally rectangular, arranged parallel to each other, separated by a certain distance and distributed preferably uniformly throughout the surface of the base board.
  • the supply strips will be arranged as demanded by the type of connection to be established between following sectors of electroconducting material, that is, due to the fact that according to the invention the mentioned sectors may be electrically connected to each other in series, each one of the strips will consecutively be connected to the alternate ends of each two consecutive sectors in the second case.
  • the supply of each panel will be executed at a voltage of 220 V, so that the heat generating paint sectors will be calculated to support said voltage.
  • the second micanite (or other non-conducting fireproof material) board has been installed over the first, only those openings necessary to execute the electric connections corresponding to the electricity mains will be visible.
  • the panel obtained in this way may be installed directly over any surface to be heated, without having to carry out any works or conditioning of said surface.
  • the perfected heating panel purpose of the invention, is constructed from a substrate, generally micanite or any other type of fireproof material, which does not conduct electricity, over which an electroconducting paint is applied over a predetermined area, specifically covering the pre-delimited areas of the substrate.
  • thermostats and adjustment components may be incorporated, so that once the temperature predetermined by the user has been reached, the passage of energy to the electroconducting areas is stopped and the latter, on not receiving energy, cut their action.
  • the external areas of the substrate are provided with a suitable coating, such as fine strips or panels of wood or similar, or another material permitting the extrapolation of the heat generated towards the exterior.
  • the conducting strips manufactured with copper will be duly insulated and protected by means of a glass or mineral wool coating, it being possible to use the insulating materials considered best for the application in question.
  • FIG 1 a board 1, represented in a schematic way, supports on one of its sides the different coatings incorporated to obtain the final panel.
  • the process has foreseen the preparation of a base board 1, manufactured in a suitable insulating and fireproof material, such as micanite or any other of similar characteristics, as has been mentioned previously, on which areas are selected for the application of an electricity conducting material in the following stage, like, for example, copper, forming the strips 4, 5, to conduct electricity when connected to a power source, such as the electricity mains, and then being applied a coating of suitable insulating material, such as, for example, glass fiber, covering said strips and extended to areas 2,3 which widely surround the mentioned electricity conductor strips 4,5.
  • a suitable insulating and fireproof material such as micanite or any other of similar characteristics, as has been mentioned previously
  • the following stage consists of the formation of a predetermined number of sectors 6, using an electroconducting paint, capable of generating heat due to its resistance when a current of electricity is passed through it, and in a way that the parts corresponding to the end edges of said sectors lean on (and also are in electric contact with) the mentioned electricity conducting strips 4,5.
  • both areas 2,3 of glass fiber and the conducting strips 4,5 have been arranged near the larger sides of a base board 1, which has a rectangular shape, parallel to said edges.
  • the sectors 6 of heat generating electroconducting paint are arranged in the transverse direction of board 1, parallel to each other, and separated by a certain distance.
  • sectors 6 receive electricity supply in parallel from the copper strips 4,5, that is, the ends of a same side receive supply from the corresponding strip 4 and the ends of the opposite side receive it from strip 5, once both strips are connected to the electricity supply, preferably to the electricity mains.
  • the second board (not represented), of the same fireproof material as the first, once connected to the described assembly, hides all the conducting and heat generating parts, so that the assembly may be handled completely normally and fitted on the surface to which it is desired to transmit the generated heat.
  • the base is a substrate 1 of micanite or any other suitable material such as ceramic or any fireproof and non-electricity conducting material, a coating of electroconducting paint, forming determined areas 7, which are interconnected by copper strips 8, duly insulated with an appropriate material 9, obtaining that the copper strips 8 generate the communication of the areas 7 coated with electroconducting paint obtaining as a result of the connection of the strips 8, to the mains, by means of the connections 10 with or without the collaboration of a thermostat or suitable adjuster, that the paint acts as a resistance generating heat towards the exterior, and finally the two faces of the substrate 1 being externally covered with wooden panels or strips, which decorate the perfected heating panel 1 allowing its suitable attachment on a surface, it likewise being possible to omit the incorporation on one of the external wooden panel faces, only covering the seen face, permitting the incorpor
