Abstract

UNDERFLOOR OR WALL SURFACES HEATING APPLIANCE. IT INCLUDES PAIRS OF PLATES 6 IN POLYAMIDE REINFORCED WITH FIBERGLASS OR CERAMIC. THESE PLATES ARE OFFSET WITH RESPECT TO ONE ANOTHER IN THE DIRECTION OF THE DUCTS AND PERPENDICULARLY THEREFORE AND HAVE GORGES 7 OF SEMI-CIRCULAR CROSS SECTION HOLLOWED ON ONE OF THE SIDES TO LODGE A COPPER TUBE COIL, OF APPROXIMATELY 6MM OF EXTERIOR DIAMETER, NOT INTERRUPTED BY CONNECTION ELEMENTS, IN WHICH ONE TO TWO LITERS CIRCULATES PER MINUTE OF PRE-HEATED HEATING LIQUID.

Description

1 2470344

  The invention relates to an underfloor heating apparatus or to wall surfaces which is distinguished by a small thickness, the absence of any risk of corrosion as well as

only by a great reliability.

  It is known to use for heating underfloor iron or plastic coils of large internal diameter, which are assembled from individual elements and are traversed by previously heated water. The connecting pieces required for this purpose require so much space that their incorporation into

  old buildings is not possible.

  The object of the invention is to provide a heating device by the floor or by the wall surfaces which is only about 12 mm thick and which can be used

  without difficulty to replace the existing heater by oven.

  This object is achieved in accordance with the invention by pairs of plates offset relative to one another in the direction of the ducts and transversely to this direction, comprising

  on one side of the excavated gorge having a transverse section

  dirty semicircular to house a double coil of copper tube, about 6 mm in outer diameter, uninterrupted by connecting pieces and in which circulate one to two liters per minute of heating liquid previously heated.

  An exemplary embodiment of the invention is described below.

  after in conjunction with the accompanying drawing, in which: - Figure 1 shows two plates according to the invention, having grooves cut in one side, of semicircular cross section; these plates are staggered one

  compared to the other in the direction of the orientation of

  as well as transversely to this direction, of a given value, at a scale of about 1:10; - Figure 2 is a section along the line II-II of Figure 3 size; and - Figure 3 shows a wall surface realized

  according to the invention, at 1:10 scale.

  A long copper tube 1 with a diameter of 6 mm and a wall thickness of 1 mm is bent to form a double coil 2, one end of which leaves the boiler in 3. changes direction by forming a short arc and returns to the

  In new constructions, these double copper tube coils can be fixed on a bottom wall provided with a thin insulating layer and can then be applied a protective layer not attacking the copper. It is assumed in the exemplary embodiment

  the heater is to be

  on a wall; according to the invention, 6 mm thick fiberglass-reinforced polyamide plates 6 having a thickness on one side are affixed to the wall.

  grooves 7 of semicircular section.

  The grooves 7 are offset relative to the middle of the plates 6 transversely to their orientation, such

  so that when one places the sides

  the gorges, these firmly surround the cooking tube.

  6, and that the plates have a transverse overhang

  badly to the tubes. This results in forces of

  tion on the plates do not cause any constraint

  These are transversal on the copper tubes, which would otherwise be feared for underfloor heating. For the return elbows 9 and 10, special plates 11 to 14 are required, compared to those provided for straight pipe parts. As heating fluid, hydraulic oil

gave the best results.

Claims (2)

  1. Underfloor or wall-type heating apparatus, characterized by pairs of glass-fiber-reinforced or ceramic-reinforced polyamide plates (6, 11 to 14), these plates being offset relative to one another other in the direction of the ducts and perpendicular to that direction and   having grooves (7) of semi-transverse cross-section   rounded on one side to house a serene   tin of copper tube, about 6 mm in outer diameter, uninterrupted by connecting elements, in which circulate one to two liters per minute of heating liquid previously heated.   Floor heating apparatus or wall surfaces according to claim 1, characterized in that the copper coil (2) is designed as a double coil, and that the inlet and outlet pipes are provided in one area of the surface heating. -.
