Definitions

  • the present invention relates to an ultraflat heating assembly having application in air conditioning industry, and more specifically in the field of dry heat electric radiators, being constituted as a heat source, mainly, in domestic heaters, subject to other uses or applications.
  • the object of the invention has a simple, low-cost construction, not requiring an outer enclosure, being highly reliable and safe, in addition to being able to be easily integrated in the already existing radiator apparatuses.
  • Such resistances transmit heat that they produce by any method, i.e., either by radiation, convection, or conduction.
  • Resistors which transmit heat by conduction have always had an electrically insulated enclosure which also served for transmitting heat, as is described, for example, in the European Patent no. EP-1574803-B1 , the Spanish validation of which is published with the no. ES-2338575-T3 , in which a dry heat modular electric radiator comprising a heating plate having a base plate, a resistance wire and an external enclosure to insert it tightly into a housing of the radiator is described.
  • the present invention relates to an ultraflat heating assembly allowing a simple, low-cost construction, in which the common outer enclosure is eliminated, being at the same time highly reliable and safe, in addition to being able to be easily integrated in dry heat electric radiator apparatuses, such as for example the radiator described in the European Patent no. EP-1574803-B1 .
  • the heating assembly proposes by the invention comprises an electroresistant conductor wire also called electric resistance, preferably made of chromium-nickel alloy, wound around a support body or core made of heat resistant and insulating material having a flat and elongated configuration, preferably made of micanite, an insulating matter formed by thin mica sheets attached to one another by means of a suitable adhesive.
  • an electroresistant conductor wire also called electric resistance, preferably made of chromium-nickel alloy, wound around a support body or core made of heat resistant and insulating material having a flat and elongated configuration, preferably made of micanite, an insulating matter formed by thin mica sheets attached to one another by means of a suitable adhesive.
  • the conductor wire transmits heat by conduction when electric current flows through said conductor wire.
  • at least one insulation plate made of heat resistant and insulating material, preferably micanite, is attached to each face of the support body.
  • the assembly comprises connectors made of steel, coupleable to the ends of the support body and connectable to each end of the conductor wire at a connection point, the support body and a coupling area of the connectors being located between at least one insulation plate, all of this forming a sandwich attached by means of pins, a cap made of elastic and insulating material closing and insulating the heating assembly from the outside is coupled to the sandwich thereof at both ends.
  • the insulation plates, as well as the support plate have an elongated configuration, meaning they are preferably rectangular plates, it is understood that their smaller sides are their ends, such that the width of the insulation plates, i.e. the dimensions of their smaller side, is greater than the width of the support plate, for the purpose of providing the resistance with an insulation equivalent to the ends not covered by the sheets.
  • the assembly comprises a cap or elastic cover element made of insulating material, such as rubber, arranged at each end of the sandwich, wherein said caps protect the connectors, since according to a preferred embodiment of the invention they are housed in said caps.
  • the assembly thus formed is to replace the heating assembly described in the aforementioned European Patent no. EP-1574803-B1 , in which the resistance and the plates were located inside a flexible outer enclosure which was press-fitted into the radiator.
  • the ultraflat heating assembly proposed by the present invention is designed to transmit heat by conduction, and has as an outstanding feature that the outer enclosure has been eliminated in its construction simplifying and limiting its construction to a very few parts and processes.
  • the possibility of alternatively using a printed circuit with conductive ink is contemplated.
  • the cap is entrusted with the following functions:
  • each face of the support body is attached to a fist insulation plate made of heat resistant and insulating material, which is in turn attached by an opposite face to a second insulation plate made of heat resistant and insulating material is contemplated.
  • first heat resistant insulation plate at each side and additionally a second insulation plate at each side allows providing the assembly with class II electric insulation.
  • the number of insulation plates incorporated by the assembly will depend on the type of insulation desired, either class I or class II. If the resistance is to be incorporated to a class II radiator, it is necessary that it comprises two insulation plates per face.
  • each end of the support body has a hole, for example made by die-cutting.
  • This hole has a geometry equivalent to that of the coupling area of the connectors, so that said connectors can be fitted in the mentioned holes of the support body.
  • the coupling area of the connectors comprises an opening to house the joint rivet which permanently attaches the support body, the insulating plates and the connector itself, to form a sandwich.
  • the coupling area of the connectors has a point to be welded to the electroresistant wire.
  • the ultraflat heating assembly proposed by the invention comprises a conductor wire (6) wound around a support body (1) made of micanite having a flat and elongated configuration can be observed.
  • the conductor wire (6) transmits heat by conduction when electric current flows through said conductor wire (6).
  • the assembly comprises connectors (4) made of steel, coupleable to the ends of the support body (1) and connectable to each end of the conductor wire (6) at a connection point (9), preferably a welding point, the support body (1) and a coupling area (4a) of the connectors (4) being located between at least one insulation plate (2,3), all of this forming a sandwich attached by means of pins (7), a cap (5) made of elastic and insulating material closing and insulating the heating assembly from the outside is coupled to the sandwich thereof at both ends.
  • the insulation plates (2, 3), as well as the support plate (1) have an elongated configuration, meaning that they are preferably rectangular plates, it is understood that their smaller sides are their ends, such that the width of the insulation plates (2, 3), i.e. the dimensions of their smaller side, is greater than the width of the support plate (1) to achieve a sufficient side insulation at the ends of the sandwich.
  • connection area (4a) of each connector (4) has a hole (1a) in which the connection area (4a) of each connector (4) will be tightly fitted.
  • the two connectors (4) are thus coupleable to the support body (1) for which said connectors (4) have a connection area (4a) with a geometry substantially equivalent to that of the holes (1 a) of the support body (1), said connection area (4a) of the connector also having an opening to house the joint rivet (7) made of brass or another material.
  • the connector (4) is a multifunction part which complies with these four tasks:
  • each connector (4) can be connected to the connection cable (8) at an end opposite to the connection area (4a).
  • the other end of the connector (4) made up a male faston terminal/connector arranged to receive the connection cable with its corresponding output connector or female faston.
  • the caps (5) are made of elastic material, allowing their fit insertion and immobilization at the ends of the support body (1), whereby the height of each cap (5) is less than the width of the insulating insulation plates (2, 3) in which said cap (5) is inserted. Rubber-silicone is considered suitable to perfectly comply with these requirements, without excluding other possible materials. To insert and immobilize it in its housing, making use of its elastic characteristics has been contemplated by making the height of the cap (5) less than the height of the insulation plates (2, 3) where it is to be fitted.
  • each cap (5) comprises at least one protuberance (5a), located inside, preferably one lower and another upper, corresponding with an upper release flange (5b).
  • said protuberances (5a) are configured to fit the cap (5) by elastic deformation in a notch (2a, 3a) of the insulation plates (2, 3) have, said cap (5) thus being fitted in the insulation plates (2, 3).
  • the insulation plates (2, 3) have notches (2a, 3a) above and below each end.
  • the cap (5) in turn has corresponding protuberances (5a) provided to be fitted in the aforementioned notches (2a, 3a), although the previously mentioned height difference, and taking into account the special form of a preferred embodiment of the cap (5), it being wider in the center and being narrow towards the upper and lower ends.
  • the cap (5) is first inserted at the lower portion, the cap (5) is at the same time stretched upwards using to that end the tongue or flange (5b) to insert the cap (5).
  • Next what left to be done is to move it until the notches (2a, 3a) and protuberances (5a) are coupled.
  • the cap (5) is thus perfectly immobilized and completely functional.
  • the cap fits tightly to the insulating plates, as shown in section B-B of Figure 2 .
  • the invention contemplates the use of a deflector visor provided to place the resistance in vertical position. To place it in a horizontal or inclined position, the deflector visor must be placed along the dimension exposed to the eventual drips of water.
  • each cap (5) has a lower opening (5c) for connecting the output connector (8) with the connector (4) housed in the cap (5), which allows the connectors (4) housed in the cap (5) to be connected to the electric power system through an faston output connector (8), which facilitates and expedites the installation thereof in a radiator protecting it from water and insulating the current.
