    Improved heater {An improved heater}
    [2] Conventionally, buildings are heated by sparsely provided radiators everywhere. The main hot water pipe is heated by the boiler and then the heated water is delivered to the individual radiators via the pipes. Water entering the auxiliary pipes provided in the radiator warms the radiator and releases heat to the surroundings by radiation, convection and heat conduction.
    [3] Such radiators may also be used to dry clothing or the like by lining articles on or near the radiator. Towel rails have also been formed in the water pipe, which forms a horizontal bar on which the water pipe can be rolled up and placed on it to be dried or aired. However, the total use of energy using these heaters is uneconomical and requires a very large amount of energy consumption to heat and maintain the temperature of the water and pump the water along the dried pipes housed around the building and inside the radiator. Pipes and radiators are also subject to pressure intensification, which in rare cases can lead to pipe rupture.
    [4] In addition, radiators are bulky and expensive. The main water pipes are provided with auxiliary pipes for delivering water to the radiator in the part where the radiators should be located in a particular building, so once installed in a particular area the radiators are difficult to move. Thus, the change in position of the radiator requires a substantial change to the piping of the system.
    [1] The present invention relates to an improved heater, and in particular is not limited to the form of heated rails for article drying.

    [29] 7 is a front elevational view of a heater showing another arrangement of FIG.
    [5] It is an object of the present invention to provide an improved heater aimed at overcoming the above mentioned drawbacks.
    [6] Accordingly, the present invention includes a first heat pipe in contact with or in fluid communication with at least one additional heat pipe extending therefrom, wherein at least one of the heat pipes is at least partially introduced and the working fluid An internal cavity for receiving, at least one of the heater pipes, provides a heater adapted to receive heat from an internal or external heat source.
    [7] Preferably, the heater has at least one vertical heat pipe in contact with or in fluid communication with a plurality of second heat pipes extending substantially horizontally therefrom. Preferably, both the first heat pipe and the second heat pipe are at least partially introduced and receive a small amount of working fluid. Each of the horizontal heatpipes may extend in the same direction, or may be spaced at regular intervals to provide a series of rails for hanging articles such as towels. Preferably, the lowest rail is positioned in contact with the heat source.
    [8] Alternatively, the first heat pipe may have a plurality of second heat pipes extending in a different direction from itself, for example, in a direction to form a star radiating outward from the central first heat pipe. Preferably, in use, the second heat pipes extend substantially perpendicularly from the first heat pipe. Preferably, the first heat pipe is housed inside the casing. Preferably, one or more brackets are provided around the first heat pipe, and each bracket may be rotated relative to the first heat pipe. The second heat pipe may be secured to the bracket or may be separated from it. The extension portion of the bracket may be hinged to allow the second heatpipe to be folded relative to the casing when not in use.
    [9] More preferably, the brackets and extension portions are dimensioned to have substantially the same size as the components respectively installed in the vertical or horizontal heatpipes. The brackets and / or extensions may be provided with compartments on each component or through which a slit or cut may be provided to receive each component. Suitable fastening means, such as Allen screws and keys, may be used across the gaps or grooves to clamp the components inside the brackets and extensions. Preferably, the bracket is provided with longitudinal slits along its length. The extending portion is preferably provided with at least one, more preferably two clearances perpendicular to the clearance in the bracket.
    [10] Preferably, the bracket is formed by mold molding.
    [11] Alternatively, the first and second heat pipes may be spiral, wherein the first heat pipe forms a vertical portion for contact with the heat source and the second heat pipe extends obliquely from itself. Or an upper portion forming a coil.
    [12] The heat source may be, for example, hot water delivered along a conduit, such as a traditional hot water pipe. The hot water may be heated by, for example, gas or electricity. In an embodiment in which the horizontal heat pipes extend in the same direction, the lowest heat pipe and the base portion of the vertical heat pipe are preferably positioned in contact with the hot water pipe. Preferably, the lower edge of the heat pipes in contact with the hot water pipe is provided with a concave surface corresponding to the ball neck surface of the hot water pipe. Alternatively, the heat pipes and hot water pipes may be surrounded by a bracket having a flat edge which enables the pedestal of the respective pipes. Preferably, the brackets are attached to each other. It is important that the brackets and pipes be made of a suitable heat conducting material such as aluminum or steel.
    [13] Alternatively, the heat source may be electricity, in which case the heatpipes are heated by an electric coil wound around all or part of the pipes or by a heating electrode arranged in one or more pipes.
    [14] The heater may be provided with an integrated heat source providing separate heater heating means, whereby the heater can be heated by or take heat from an external heat source. Where an integrated heat source is provided, it is preferred to have an electrical heating electrode arranged on at least one of the heat pipes. Preferably it is disposed in a vertical heat pipe. When an integrated heat source is provided, the heater does not rely on having one of the heat pipes adapted to receive heat from an external heat source.
    [15] Alternatively, the internal heat source may be provided by a heat transfer pipe extending to the inner end of the first heat pipe, the heat transfer pipe transporting a heat transfer medium such as water. Preferably, the heat transfer pipe is open at an end to transfer a heat transfer medium to the first heat pipe, and the first heat pipe is sealed at both ends but for transferring the heat transfer medium away from the heater. Has an outlet port. In this embodiment, only the second heat pipes are self-contained units which may be introduced in part. Also, a large number of second heat pipes may extend from the first heat pipe, and the second heat pipes are secured therein or rotated.
    [16] Alternatively, the internal heat source may extend through one or more horizontal heat pipes. Preferably, the hot water pipe passes through the interior of the lowest heat pipe, which is a sealed and partially introduced self-contained unit.
    [17] The heater of the present invention is provided for changing the heat transfer direction. Preferably, in use, the horizontal heatpipes are inclined slightly upwards from the vertical heatpipe, for example from +0.1 to 5 ° from the horizon.
    [18] For example, it should be appreciated that all introduced heat pipes are sealed at the free end to provide a self-contained unit that may be partially introduced by a valve provided on one or more heat pipes.
    [19] The heater of the present invention may be provided with a cover to provide a traditional radiator. Preferably, the cover is removable.
    [20] In addition, the heater may be provided with a buffer to prevent any pot function. Preferably, the buffer is in the form of a wire mesh, such as a stainless steel mesh provided on or around the heat source.
    [21] In a preferred embodiment of the present invention, there is provided a heater having a vertical first heat pipe rotatably installed and spaced apart and positioned in a series of substantially horizontal heat pipes. The vertical heatpipe may be secured to the wall or other surface, for example by providing a suitable wall bracket attached to the wall and all horizontal heatpipes may be adjusted to be positioned against the wall in a ladder shape. Preferably, additional stabilizing bars are provided parallel to the vertical heat pipes for receiving the free ends of the horizontal heat pipes. In a ladder shape, retaining means such as clips may be provided at appropriate locations on the stabilizing rods for receiving and retaining the horizontal heat pipes. The horizontal heatpipes may be discharged from their retainers and may be rotated outward from the wall if necessary. External and / or internal heat sources may be provided in contact or fluid communication with the vertical heat pipe and / or the lowest horizontal heat pipe.
    [30] Referring to FIG. 1 of the accompanying drawings, a heater 2 according to a first embodiment of the invention is shown. The heater has a vertical heat pipe 4 in fluid communication with a plurality of horizontal heat pipes 6a, 6b, 6c, 6d, 6e, 6f, 6g extending substantially perpendicularly from it. The horizontal pipes are slightly upwards away from the vertical pipes, for example, at an approximately + 2 ° inclination from the horizontal plane. Both vertical and horizontal pipes are partially introduced and emptied both at the free end to receive a small amount of working fluid, such as water, and to draw up a self-contained unit. One or more pipes are provided with a valve 8 to enable its own introduction and to allow the introduction of a working fluid. The inner wall of the heat pipes must be protected against the effects of corrosion due to the presence of the working fluid.
    [31] The bottom of the vertical pipe 4 and the lowest horizontal pipe 6a is installed in contact with a heat source in the form of a pipe 10 carrying a heat transfer medium such as, for example, water heated by a gas boiler. The pipe is a traditional pipe with a heat transfer material. 2 of the accompanying drawings shows one mechanism for attaching the lowest horizontal pipe to the heat source, it is important that other installation forms may be used for the heater of the present invention. Both the hot water pipe 10 and the horizontal heat pipe 6a are partially surrounded by a delivery bracket 12 with flat edges 14. Each flat edge of the brackets is sealed to each other using an adhesive that helps to efficiently transfer heat from the hot water pipe to the heat pipe.
    [32] In this way, the hot water pipe can heat not only the base portion of the vertical heat pipe 4 but also all lengths of the lowest horizontal pipe, thus evaporating below the standard boiling point according to the vacuum present inside the heat pipes. The working fluid is heated by the heater 2. The reduced pressure inside the heater allows the fluid to move quickly therein and, of course, is condensed to release the latent heat of condensation to transfer heat to the wall of pipes and thus to the ambient atmosphere. The fluid is recirculated to provide a continuous source of heat to the area provided with the heater. The horizontal arms 6a-6g of the heater are adapted to be particularly suitable for drying and airing articles such as towels that do not need to provide a rolled pipe that requires a continuous flow of hot water to be pumped into it. It is a heater.
    [33] The actual volume of fluid contained in the internal cavity of the heater will depend on the specific dimensions of the unit. Similarly, the volume of vacuum present inside the heater is important for its efficient operation. The volume will depend on the size of the pipes, the temperature required and the volume of the working fluid and may be obtained by the laws of thermodynamics.
    [34] The heater according to the invention enables heat to be transferred in the horizontal direction as well as in the vertical direction through the partially introduced pies. The lowest pipe is heated by the hot water pipe causing evaporation of the working fluid therein. This is due to a slight inclination which flows backwards along the pipe and is re-evaporated by the heat which has been conducted to the vertical pipe ends. This process makes it possible to heat the heater very quickly and efficiently.
    [35] It is important that the heater may be provided with an alternative heat source such as electricity. In this embodiment, energy may be supplied via the main power source. This enables the heater to be provided as a standalone unit, so that it can be located anywhere, assuming that the heater can be connected to the mains power supply. Alternatively, the lowest horizontal heat pipe may be provided to the internal heat source. For example, a heat transfer pipe may extend through the lowest heat pipe. The heat pipe is self-contained, partially introduced and a working fluid is provided. The sealed heatpipe is completely separated from the heat transfer pipe extending therefrom and transfers a heat transfer medium, such as gas or water, to affect the heating of the heat pipe.
    [36] A buffer in the form of a wire mesh or metal mesh, for example a wire mesh or a metal mesh, is used to dissipate and destroy molecules within the system but to prevent any undesirable unwanted pot activity occurring inside the heater. It may be provided on or around. The size of the mesh or net depends on the actual size of the heater unit and the number of watts of the heating electrode.
    [37] The unit may also be enclosed in a cover that provides a radiator. This cover may be removable so that the heater can be used as a towel rail if necessary.
    [38] The heater has many advantages over those of the prior art. First, the heater does not require internal piping to flow water around. Since there is no need to pump water around the rolled pipes of a traditional radiator or tower rail, this can reduce the pressure on the pump of the main heating system that delivers hot water around the building. The heater may be fixed to a hot water pipe or other heat source at any suitable location, thus significantly increasing the flexibility of the heater location, and in fact may be provided as a self-contained unit. In addition, the heater will normally operate up to approximately 100 ° C. at negative pressure depending on the fluid inside the heat pipes. Thus, the unit will have to withstand low pressure even at high temperatures. In contrast, prior art radiators always have a positive pressure that increases when the temperature of the medium in the radiator rises. Not only does this result in the heater of the present invention being safer to use, but also because of the reduced pressure inside the unit caused by partial vacuum, the heater may be made of a lighter and thinner material. The reduced volume of water must also be heated and delivered around the building, providing a much more efficient heating system. The heater may eliminate plumbing present in buildings.
    [39] 3 and 4 of the accompanying drawings show an alternative embodiment of a heater according to the invention. The heater 20 has a vertical sealed heat pipe 40 extending from the vertical heat pipe 40 and wrapped by a cylindrical casing 42 having a large number of horizontal sealed heat pipes 44. do. The base portion of the heat pipe 40 is in contact with a heat source 50 that transfers heat to the heat pipe to heat the horizontal heat pipe 44. The horizontal heat pipes 44 are attached to the casing 42 by one or more brackets 46a and 46b provided sparingly on the casing. The bracket is fixed in the vertical direction because of the presence of the flange 48 but can rotate around the central heatpipe 40 because of the presence of the slot 52 in the casing 42 (see arrow B in FIG. 4). The heat pipes 44 may be temporarily drilled into the socket formed by the branch pipe 46b of the bracket or may be welded there forever by a heat transfer pool. In addition, the branch pipe 46b of the bracket is rotatably installed on the main body 46a of the bracket to enable the horizontal pipes to be folded about the casing 42 (arrow A direction shown in FIG. 4). ).
    [40] In this manner, the heater may be provided as a self-contained heater with horizontal pipes 42 extending out therefrom to act as a rail for supporting clothing such as a towel or the like. The rails may be rotated relative to the vertical pipe or may be folded against the casing for easy storage when not in use. Each bracket may be provided with a large number of branch pipes extending therefrom to accommodate horizontal heat pipes, which results in extending the rails outward around the periphery of the casing. In addition, a plurality of brackets may be provided spaced apart to provide a rail layer on the vertical pipe.
    [41] The bracket may be dimensioned substantially in the same size as the components installed therein, ie the vertical or horizontal heatpipes. The bracket and its extension portion for receiving the horizontal heat pipe may be provided with a groove or a gap therethrough so that the portion is provided on each component or can accommodate each component. To clamp the parts inside the bracket, suitable fastening means such as allen screws or keys may be used across the grooves or gaps. In one embodiment, the bracket provided on the vertical heat pipe is provided with a vertical slit along its longitudinal direction and the extension portion accommodating the horizontal heat pipe is perpendicular to a slit in a bracket (not shown). Two slits are provided. The bracket may be formed by mold molding.
    [42] Alternatively, the heater may be provided with an internal heat source as either a standalone unit or a traditional heating system. 5 of the accompanying drawings shows a heater according to one embodiment of the present invention, the vertical pipe 100 is provided with an internal heat source 104 for heating the horizontal heat pipes 102. In this embodiment, only the horizontal heatpipes forming the rails of the heater are partially introduced and receive a small amount of working fluid. For example, the vertical pipe 100 having a diameter of 28 mm is not introduced and a stopper is formed at one end and opened at the other end. For example, a small pipe 104 having a diameter of 15 mm is placed in the center of the pipe and a disc 106 is provided around the inner pipe near the base portion of the outer pipe to seal the faces of the inner and outer pipes. Therefore, the flow of the open end of the outer pipe is prevented. One end of the inner pipe inside the outer pipe is open and the other end is in fluid communication with a standard hot water pipe (not shown). The outer pipe 100 is provided with an outlet port 108 proximate its base portion.
    [43] In this manner, hot water may be delivered to the end of the inner pipe 104. At the top of the pipe, the water heats the outer pipe because it flows into the outer pipe. The self-contained, partially introduced heat pipe 102, which is attached by the bracket 110 and extends horizontally or obliquely from the vertical pipe, is heated by the vertical pipe. The water then exits from the vertical pipe, for example by an outlet 108 which will be reheated by a traditional boiler system.
    [44] It should be appreciated that the heat pipes may be secured to a vertical pipe, as described above with respect to FIGS. 3 and 4, and may be secured there rotatably. A large number of heatpipes may extend from the central vertical pipe to form rails for hanging the article.
    [45] In another embodiment of the present invention, a heated towel rail is provided that is compatible between a ladder towel rail and a swinging towel rail, as shown in FIGS. 6 and 7 of the accompanying drawings. The vertical heat pipe 200 is secured to a wall bracket (not shown) installed on the wall (W). A parallel metal fastening bar 208 with spaced retaining clips 210 is provided at a distance from the vertical heatpipe. The horizontal heat pipes 202 are rotatably installed with respect to the vertical heat pipe by the bracket 206. The horizontal heatpipes may be secured to the retainers 210 in the fixed bar 208 so that they can function as a ladder towel rail by placing against the wall (see FIG. 6). Alternatively, one or more horizontal heatpipes may be withdrawn from each retainer and rotated outwards (as shown in FIG. 7).
