FR2849497A1 - Water-filled radiator has rotary tubes with valves across two main tubes to give variable heating area - Google Patents

Abstract

The radiator consists of two parallel main tubes (1) linked by a series of transverse rotary tubes (2) with closed ends and valves formed by three holes (8, 9) at 90 degrees to one another inside the main tubes. The radiator consists of two parallel main tubes (1) linked by a series of transverse rotary tubes (2) with closed ends and valves formed by three holes (8, 9) at 90 degrees to one another inside the main tubes. The transverse tubes have projecting ends (11) for rotating them and setting their positions, and their outer surfaces between the two main tubes have radiating fins (10) that can be V-shaped or in spirals, and they have seals (5) round their joints. By rotating the transverse tubes the heating surface of the radiator can be increased or reduced.

Description

The present invention relates to a surface heating device

variable heating.

  The conventional radiator offers no possibility of modifying the quantity of heated water. It only allows to regulate the flow rate thanks to the stop valve, which can cause a thermal conflict between the arrival and the exit of water to the boiler, which consequently must provide a considerable quantity of energy to balance the difference in temperatures.

  The device according to the invention overcomes this drawback.

  It consists of two parallel mother tubes (1) through which transversely fixed tubular elements (2) are fixed transversely. The tubes and the elements have the same inside diameter and very thick walls. The outside diameter of the tubes is proportionately larger, allowing the elements to fit together.

  The elements are minced (3) over the length corresponding to the diameter 5 of the tube $ mèrd'afin allow the attachment of the assembly by nuts (4).

  The sealing between the elements and the mother tubes (5) can be done using silicone seals stored between metal washers.

  The tubes "have on one side the inlet and for the other the water outlet and for the first on the other side a drain (6) and for the other on the other 20 side, a drain valve or plug (7). The cut of the mother tubes can be round, rectangular or rectangular.

  The elements are drilled at the intersection with the mother tubes by three holes (8) of the same diameter as the inside diameter of all the tues and closed at the end. The angular spacing of the holes is 90 "for the first, 25 then 900 between the first and the second and 1800 between the first and the third.

  Thus the elements form valves Y of the tower. A simple version can have only two holes (9) with an angular spacing of 1800 usable only on the last elements so as not to completely cut off the circulation of the fluid in the radiator.

  This arrangement of the orifices allows the transit of the liquid or the reduction of the circulation individually by each of the elements and thus makes it possible to adjust the temperature of the room by varying the heat exchange surface of the radiator by selecting the number of the heating elements.

  Thanks to this possibility, the quantity of heated water is reduced at the same time, which saves energy.

  As the circulating water temperature is constant, this reduces the heating time and provides additional energy savings.

  To increase the heating surface, the through elements (2) can be equipped with a surround defined by one or more fins in the form of a spiral or chevron (104) (4oi).

  According to the selected mode elements (2) pres ent extensions (11) which protrude on one or both sides the mother tubes (1) thus serve as rotating handles acting as closing-opening thanks to a polygonal section, for example , to facilitate handling allowing the rotation of the L4 5 elements with locating means (14) or indexing making it possible to display or locate the opening or closing positions i4A "(4i S). In the case o the elements do not protrude from the tubes & meter: this is the interior part located between the two "mèrê" tubes, the outside diameter of which allows the luiseul already a good grip which can alternatively be increased if necessary by a polygonal shape for example and also comprising means element, which serves as a handle.

  By way of nonlimiting example, the inside diameter (12) of the mother tubes (1) ft the inside diameter (13) of the elements (2) will be 15 mm and the outside diameters respectively of 45 mm for the elements and 90 mm for the "l" mother tubes will preferably be made of cast aluminum.

  The device according to the invention is particularly intended for central heating. The accompanying drawings represent: - fig. 1 a front view of the radiator according to the invention.

  fig.2 a horizontal sectional view along A - A at the axis of the hole in the upper tube. - Fig.3A and 3B views in horizontal section along B - B transverse to a tubular element showing two types of exchange fins - Fig.4 a top view along arrow F of the upper extension of a tubular element serving as a rotary operating handle making it possible to adjust the angular position of the interior openings of the tubular element allowing the passage of the fluid longitudinally to supply the following elements and / or transversely in the direction from top to bottom which can short-circuit the following elements.

  With reference to FIG. 1 o only two elements at the final end of the radiator are represented with orifices defining one — a valve with two aligned orifices and the second. A valve with three orifices arranged perpendicularly to each other, it is understood that all of the tubular elements have such holes in the upper and lower parts.

  The device according to the invention can make it possible to use the radiator without a normal or thermostatic flow control valve.
