Definitions

  • the present invention refers to an electric heater or heating radiator.
  • the object of the invention is to simplify the constructive structure of radiators by achieving that this is implemented in a simple and modular manner and the manufacture of which is easy. It is based on assembling aluminium profiles made to engage on each other by simply applying pressure, without screws, and it has an internal heating system which transmits the heat by conduction to the aluminium profiles which in turn release it into the surroundings by radiation and by convention.
  • radiators built in aluminium, one with ingress and egress of water and another with a closed chamber containing a thermal liquid (oil).
  • a thermal liquid oil
  • previously heated water usually flows through the radiators.
  • the oil is heated by means of an electric resistance with which the radiator is equipped.
  • the radiators employed up to now are formed from injected aluminium elements which are joined to each other, by means of left-hand and righthand thread couplings, the constitution of the radiators being quite complicated for this reason.
  • radiators which work with water
  • a pipe system and a boiler which together with the radiators themselves constitute an interconnected and also interdependent installation.
  • the patent US-6 205 290 describes an electric heater including a receiving chamber farmed by heat sinks members.
  • the modular electric radiator which constitutes the object of this invention is built in aluminium in accordance with a particular structural design, has an alternative form of heating and offers safe operation with electric protection similar to that of the insulated resistance elements, without chambers under pressure and without fluid, with significantly improved characteristics in comparison with the radiators cited in the previous section.
  • the radiator of the invention has been conceived to avoid or resolve the problem which a receptacle under pressure and with oil or water signifies. They also provide enhanced electrical safety, within costs below those of radiators with conventional resistance elements.
  • the radiator is constituted from a profile of extruded aluminium, which has a series of parallel fins, the configuration of which allows good dissipation and emission of the heat, and also it can be assembled to the following profile and successively to all those that constitute the radiator.
  • the fins have on their ends a kind of confronting hooks which facilitate their coming together by displacement on inclined planes until they interlock on reaching the anchor point impeding their return and leaving the radiator mounted.
  • the modular radiator object of the invention also has the particularity that it has at least one housing into which is inserted, transversally to the profiles, a heating plate, which constitutes one of the essential features of the invention and which, due to the special configuration thereof, achieves an effective transmission of heat by conduction with maximum electrical safety.
  • the incorporation of two or more housings at different heights in the structure constituting the radiator allows the incorporation of two or more heating plates which can be located strategically to achieve a more uniform diffusion of the heat and obtain homogeneity of the temperatures in the surroundings.
  • the heating plate incorporates one or more resistances of resistance wire wound on some base boards of insulating material, usually Micanite, which are mounted, in sandwich form, between two sheets of the same insulating material and of such dimensions that they surpass the external boundary of the resistances with the object of obtaining perfect electrical isolation in all directions.
  • Some base boards of insulating material usually Micanite, which are mounted, in sandwich form, between two sheets of the same insulating material and of such dimensions that they surpass the external boundary of the resistances with the object of obtaining perfect electrical isolation in all directions.
  • the emergence of the insulated cables from the interior allows an entirely safe electrical connection.
  • This "sandwich” is inside an external enclosure of aluminium sheet which through a stamping process is constituted in a closed, hollow and elastically compressible profile provided with prominent sectors alternating with recesses which define cavities of different size.
  • the wider cavities define a total thickness of the enclosure somewhat greater than the width of the housing foreseen in the extruded aluminium profiles and the less wide cavities are somewhat larger than the thickness of the Micanite "sandwich".
  • the narrower and more rigid cavity in the enclosure forces the entire enclosure to be compressed elastically, assuring a constant pressure between the resistance wire and the Micanite sheets, which pressure is transmitted from the sheets to the aluminium enclosure and, finally from the enclosure to the extruded profiles, achieving thereby an effective chain for transmission of heat by conduction from the interior to the body of the radiator.
  • the heating plate consists of a closed, hollow, elastically compressible profile, which conforms an aluminium enclosure obtained by a stamping or rolling process which incorporates a central tubular receptacle in which is held a straight shielded tubular resistance element which has electric terminals on each end for their connection to the electricity mains.
  • the closed profile alternates two prominent sectors of preferably trapezoidal configuration with a recess of the same configuration in which the tubular receptacle is defined.
  • the width of the closed profile, defined between its prominent sectors, is greater in size that the foreseen width of the housing defined between the fins, so that in the tubular receptacle the resistance is mounted with play, in such a way that on introducing the heating plate in the housing defined between fins, the enclosure is forced into elastic compression and remains adapted in said position, and also the tubular resistance is subjected to pressure in the tubular receptacle, achieving in this way an effective chain of transmission of heat by conduction from the resistance to the fins.
  • the radiator is finished in the upper part with a piece which closes each profile favouring the diffusion of the heat which rises by convection, as well as protecting the edges produced in the operation of obtaining the profile by cutting, achieving at the same time an aesthetically very attractive finish.
  • This finishing piece is inserted by simple pressure inside each aluminium profile, having fins which allow its insertion but impede its extraction.
  • the radiator so constituted offers a high efficiency for its special configuration, and also allows power consumption to be controlled by means of electric devices and programmers which are incorporated therein, and requires no type of installation or building work, nor boilers, gas flues, pipes, etc., and needs no type of maintenance.
  • the heat which the disclosed modular electric radiator delivers is healthy, free from odours and with a uniform distribution of the heat, it being possible to program each of them independently and even displace them with no problem from one location to another.
  • the modular electric radiator implemented in accordance with the object of the invention comprises two or more profiles (1, 1'), preferably of aluminium which are assembled to each other and are equipped with parallel heat dissipating fins (2, 2', 2") forming a modular assembly which incorporates at least one electric heating plate (4, 4') inserted in at least one housing (5) defined between the heat dissipating fins (2, 2', 2").
  • the heating plate (4, 4') has an external enclosure (11, 11') which can be of aluminium obtained by stamping, consisting of an elastically compressible closed symmetrical profile of width slightly greater than the width of the housing (5) for the press-fitting thereof into said housing (5).
  • the housing (5) in which the electric heating plate (4, 4') is inserted will usually be defined between two central dissipating fins (2") and its width will correspond to the spacing between those two central dissipating fins (2").
  • the heating plate (4) comprises one or more base plates (7) of Micanite, on which a resistance wire (8) is wound, which are located between a pair of sheets (9), also of Micanite, configuring a sandwich (10) which is completed with the external enclosure (11) which has prominent sectors (12) alternating with recesses (13), which recesses (13) define in their interior a cavity of width slightly greater than the thickness of the sandwich (10), which is compressed elastically on inserting the heating plate (4) in the housing (5) assuring a constant pressure between the resistance wire (8) and the Micanite sheets (9) and between these and the external enclosure (11) of aluminium.
  • an effective transmission of heat is achieved by conduction from the resistance wires (8) to the outermost sector of the profiles (1, 1'), and from these to the surroundings.
  • the radiator incorporates at least a second electric heating plate (4'), as is represented in figure 8 , which comprises a hollow, elastically compressible enclosure (11'), which incorporates a central tubular receptacle (7) which houses a straight, shielded and tubular resistance (15) which has electric terminals on each end for its connection to the electric mains.
  • a second electric heating plate (4') as is represented in figure 8 , which comprises a hollow, elastically compressible enclosure (11'), which incorporates a central tubular receptacle (7) which houses a straight, shielded and tubular resistance (15) which has electric terminals on each end for its connection to the electric mains.
  • the enclosure (11') is formed on its sides by prominent sectors (12'), of configuration preferably trapezoidal, alternating with a recess in which there is a tubular receptacle (7) of slightly greater diameter than the diameter of the resistance (15) which is fixed to the enclosure (11') by elastic deformation of this on being inserted into the housing (5).
  • each profile (1) has some internal fins (2') of greater length than the rest of the fins (2, 2") provided with means of engagement on their ends (3) for their anchoring with complementary other means of engagement (3) defined on the internal fins (2') of the contiguous profile, the central fins (2") and side fins (2) remaining with their edges at scant distance from those corresponding on the contiguous profile (1') to guarantee transmission of the heat.
  • the means of engagement (3) of each of the profiles (1, 1') consist of some latches (3) by way of opposing hooks provided with inclined planes which facilitate their approximation until reaching an anchoring point in which they latch impeding their return so that the profiles (1, 1') are coupled and the radiator is mounted.
  • the heating plate (4, 4') can be retained in a lower housing (5) by means of a closing cover (6), as is observed in figure 4 , said closing cover (6) being coupled underneath between the central dissipating fins (2").
  • the profiles (1, 1') with the heating plate (4) can be enclosed in an external casing, the radiator being thereby suitable for locating anywhere with no need for building work nor installations of any type, including appropriate means for the control of power and temperature.
  • the radiator incorporates a finishing piece (14) on its top part which is fitted by simple pressure on each of the profiles (1, 1') favouring the diffusion of heat which rises by convection and protecting the edges of the profile.
