Definitions

  • the invention relates to an electric heater comprising, inter alia, at least two glass panels, as well as a method of manufacturing such a radiator.
  • the circuit electric is aluminum based and arranged between two polyethylene terephthalate (PET) films, which induces a relatively high cost price compared to the power obtained. PET films are relatively thermally insulating, which affects performance energy consumption of the radiator.
  • PET films are relatively thermally insulating, which affects performance energy consumption of the radiator.
  • resistance in aluminum cannot be soldered on wires copper supply and, in case of condensation, a such resistance may be the place of primers or breakdowns, especially in the junction area with the supply films, to the point where the radiator becomes unusable.
  • the invention relates to a radiator comprising at least two glass panels between two of which a resistive circuit is arranged, characterized in that that this resistive circuit is based on glass and silver and deposited by screen printing on a side face of a first panel facing a second panel.
  • the invention it is not necessary to have use of PET films to position a circuit resistive compared to glass panels, because the screen printing, which is a technique known in others areas, allows both the formation of the resistive circuit and its positioning on one of the panels.
  • Use of silver mixed with glass, in particular sintered glass, allows to build a circuit with good electrical properties, mechanical resistance satisfactory and an ability to be soldered onto the wires in supply copper from the mains.
  • This process can be implemented in a way industrial with a high degree of reliability and reproducibility and allows economical manufacturing of electric heaters.
  • the radiator 1 shown in Figures 1 to 3 is intended to be mounted on a vertical partition C. It includes three glass panels, namely a panel intermediate 2 disposed between a front panel 3 and a rear panel 4.
  • the three panels 2, 3 and 4 are made of tempered glass and are assembled into a multi-layered structure as well as appears from the explanations which follow.
  • a baguette upper 5 and lower rod 6, respectively provided with end caps 51 and 61 are provided to be mounted in the upper and lower parts of the radiator 1 by receiving panels 2, 3 and 4 in grooves 52, respectively 62, of adapted geometry.
  • uprights 7 and 8 are provided to connect the strips 5 and 6 on the rear of the radiator 1 and allow the fixing of the radiator 1 on partition C, while stiffening all
  • angles unrepresented metal can be used for immobilize the panels 2, 3 and 4 in the grooves 52 and 62.
  • the upright 8 supports an electronic unit of regulation of the operation of radiator 1, this unit being supplied with current from the mains, as represented by wire 91.
  • Unit 9 is also connected to panel 2 by a current supply wire 92 of a resistive circuit 10 affixed on the face 21 of the panel 2 facing the rear panel 4.
  • the circuit 10 is formed on the face 21 of the panel 2 by means of a device 101 for depositing, by screen printing, a bead 10 'formed by a mixture or ink based on sintered glass, silver and an organic binder. such as, for example, ethylcellulose. Sintered glass is loaded with lead to lower its melting temperature.
  • the geometry of the circuit 10 is obtained by a displacement of the device 101, in space, as represented by the arrows F 1 , F 2 and F 3 in FIG. 4.
  • the bead 10 ′ is formed by screen printing on a blank 2 ′ of glass panel not yet tempered.
  • the blank 2' is conveyed, for example by a conveyor 102, to an oven 103 which comprises a first part 103 a in which the blank 2 'is brought to a temperature between approximately 700 and approximately 800 ° C., before the blank is cooled in a portion 103 b , during a quenching operation of the panel 2, which can take place by any known technique, in particular by blowing air fresh.
  • the glass used in the ink for forming the cord 10 ' is selected such that its melting temperature is lower than the heating temperature of the blanks 2' in part 103 of the furnace 103.
  • the glass melts during transit of the blanks 2 ′ in the furnace 103, which leads to the formation of the circuit 10.
  • the organic binder of the cord 10 'affixed to the blank 2' is removed by evaporation, combustion or other physical phenomenon, so that remains on the panel 2 as the mixture of molten glass and silver which then constitutes circuit 10.
  • the panel 2 can be moved onto a cart 104.
  • the panel 2 disposed on the carriage 104 can then be routed to a next workstation in which it is assembled with a panel 3 and a panel 4 to form a multi-layer structure 234 on which elements 5 to 9 are then mounted.
  • the face 31 of the panel 3 facing the panel 2 and the side 41 of panel 4 facing panel 2 are each coated with an adhesive layer 32, respectively 42, allowing the formation of structure 234 independently the use of sticks 5 and 6.
  • the face 43 of the panel 4 opposite the panel 2 is, meanwhile, coated with a metallization layer 44 to reflect the thermal radiation from of circuit 10 during operation.
  • the panel 3 can be provided with a decoration allowing personalization the appearance of the radiator 1 and to hide the circuit 10.
  • Unit 9 includes a thermostat 93, a button setting 94 and an on / off switch 95.
  • Unit 9 is also associated, by a wire electric 96, to a temperature sensor 97 affixed to the rear face 43 of panel 4.
  • the output signal from sensor 97 is used by a logic part 98 of unit 9 to maintain the temperature of structure 234 to a value below a predetermined threshold value, for example equal to 90 ° C.
  • a predetermined threshold value for example equal to 90 ° C.
  • the sensor 97 can be of any known type, for example bi-metallic example.
  • the invention has been represented with a radiator comprising a single resistive circuit. It applies however to a multi-circuit radiator which can be distributed on both sides of the intermediate panel when a front panel is used.
