Definitions

  • the present invention relates to a heating radiator comprising at least two radiant elements for the passage of a heat transfer fluid, in which the two radiant elements consist in tubes.
  • radiant elements will be defined as "elements" in the description below.
  • Traditional radiators, in particular heating radiators, according to the known technology comprise more than one element.
  • each radiator element is typically connected to the delivery and return conduit.
  • the elements are fed in parallel with heat transfer fluid from the delivery conduit, meaning that the hot fluid, typically water, fed by the delivery conduit and coming from the heating system, simultaneously passes through all the radiator elements, which are fed in parallel with heat transfer fluid.
  • the heat transfer fluid is then conveyed from the elements into the return conduit, which in turns conveys the heat transfer fluid back into the installation.
  • the delivery conduit is provided on top of the radiator and the return conduit is provided on the bottom of the radiator.
  • the height of the delivery and return conduits is basically equal to the vertical dimension of the radiator and are normally positioned on the right and left-hand side of the radiator, respectively.
  • radiator limits the number of possible configurations of radiator to be realised, being always necessary to foresee two conduits, one for feeding and one for discharge, e.g. delivery and return conduits.
  • the purpose of the present invention is to realise a radiator able to provide a simple, inexpensive solution to the drawbacks of known radiators.
  • a heating radiator comprising at least two elements provided with a passage for a heat transfer fluid, in which the two elements are installed in series with respect to the delivery of the heat transfer fluid.
  • the elements are fed in parallel with the heat transfer fluid from the delivery conduit, meaning that the hot fluid, typically water, fed by the delivery conduit and coming from the heating system, consecutively passes through the radiator elements, which are fed in series with heat transfer fluid.
  • the heat transfer fluid enters the delivery conduit, passes through the heating elements and is finally conveyed from the last element into the return conduit that directs it back to the installation.
  • a first advantage consists in the fact that the delivery and return conduits do not necessarily have the same length as the radiator and are extremely reduced in size, possibly consisting in a simple union that connects the radiator to the heating system.
  • the various elements of the radiator are connected with simple unions that connect each element to the following or preceding one, thus ensuring the continuous passage of the heat transfer fluid.
  • a further advantage of the present invention consists in the fact that the feeding in series of the elements allows to produce a large number of configurations, without being limited by the presence of a delivery and a return conduits with basically the same length as the radiator.
  • radiator according to the present invention has a light-weighted and inexpensive structure, because of the extreme compactness of the delivery and return conduits.
  • Fig. 1 relates to a preferred embodiment of the said radiator according to the present invention.
  • Fig. 1 illustrates a radiator (1), in particular a heating radiator, comprising three elements (2), obtained according to the present invention.
  • the elements (2) are vertical elements.
  • the elements (2) have a cylindrical tubular shape, although any type of shape is possible.
  • the elements (2) are connected by means of unions (3) that allow for the passage of the heat transfer fluid between the elements.
  • the union (3) has a cylindrical tubular shape.
  • Figs. 2 and 3 show a longitudinal cross-section view and a detail of the longitudinal cross-sectional view of the embodiment shown in fig. 1 .
  • the elements (2) are divided into two chambers, a first (6) and a second chamber (6A), for example by means of a partition (4). Nevertheless, the two chambers may be obtained in different ways, as illustrated below.
  • the two chambers (6, 6A) are communicating chambers.
  • the partition (4) has a rectangular shape, the length of the longer side being lower than the length of the longitudinal cross-section of the element (2), such as to create communication between the first chamber (6) and the second chamber (6A) in the proximity of the end opposite to the union (3), as shown in fig. 2 .
  • the union (3) connects all the elements (2).
  • the union (3) is advantageously obtained as a single tube that passes through all the elements and communicates with them by means of suitable openings, it being also provided with walls (5) that divide the union (3) into different sections, thus fractioning the tube of the union.
  • the union (3) is provided with walls (5) in the partitions (4), which separate the tube of the union (3) in different areas, each area being comprised between each pair of elements (2).
  • This type of union which consists in a tube provided with walls, is especially advantageous because it allows for easy installation of the union on the elements with a lower cost, if compared with individual unions installed between each pair of elements.
  • the heat transfer fluid is conveyed from the union (3) into the first chamber (6) of the first element.
  • the heat transfer fluid flows in the first chamber (6) of the first element along the partition (4), reaches the end of the partition (4) and passes into the second chamber (6A) of the first element.
  • the heat transfer fluid After passing through the second chamber (6A) of the first element, the heat transfer fluid flows into the union (3) and is conveyed into the first chamber (6) of the second element.
  • the heat transfer fluid flows in the first chamber (6) of the second element along the partition (4), reaches the end of the partition (4) and passes into the second chamber (6A) of the second element.
  • the heat transfer fluid After passing through the second chamber (6A) of the second element, the heat transfer fluid flows into the union (3) and is conveyed into the first chamber (6) of the following element.
  • the heat transfer fluid After passing through the second chamber (6A) of the last element, the heat transfer fluid flows into the union (3) and is conveyed into the heating system.
  • First element means the element that is fed first
  • second element means the element that is fed second
  • the division of the element (2) in two chambers is obtained by means of systems with an external and an internal tube, that is to say of the so-called “tube-in-tube” type.
  • Figs. 4 and 5 show a second preferred embodiment of the present invention in which the elements are installed in series relative to the feeding direction of the heat transfer fluid.
  • the elements (20) are horizontal elements and are connected by the union (30).
  • the union (30) is obtained as a single tube with square cross-section.
  • the union (30) is connected to a free end of the elements (20).
  • the elements (20) and the union (30) have a parallepiped shape with polygonal cross-section, specifically a square shape according to this embodiment.
  • the elements (20) are divided into two chambers, a first chamber (60) and a second chamber (60A) by means of a partition (40).
  • the partition (40) protrudes in the area of the element to be mated with the union (30) with respect to the walls of the same element (20), at a distance and with a shape basically complementary to the ones of the internal volume of the union (30) in the mounting area, such that the partition (40) acts as divider between the first chamber (60) and the second chamber (60A) of the element (20) and also as wall for the union (30).
  • the length of the partition (40) is lower than the longitudinal cross-section of the element (20) such as to put in communication the first chamber (60) with the second chamber (60A), as illustrated for figs. 2 and 3 .
  • Figs. 6 and 7 illustrate an additional embodiment of the present invention in which the elements (200) of the radiator (100) are installed in series with respect to the delivery of the heat transfer fluid.
  • the union (300) is positioned on the body of the elements (200), and not at the ends, such in the previously illustrated embodiments.
  • the heat transfer fluid passes through one element (200) at a time.
  • the heat transfer fluid is conveyed by the union (300) into the first chamber (600) of the first element.
  • the union (300) is positioned on the body, or in intermediate position, of the elements (200), the heat transfer fluid passes through the first chamber (600) of the first element in both directions.
  • the length of the partition (400) is lower than the length of the longitudinal cross-section of the element (200) and provides communication between the first (600) and the second (600A) chamber in the proximity of the two ends of the said elements (200).
  • the flow of the first chamber (600) passes into the second chamber (600A) and is then conveyed in the union (300).
  • the flow passes into the first chamber (600) of the second element. Basically, half of the fluid passes through the first chamber in one direction and the other half of the fluid passes in the opposite direction.
  • the heat transfer fluid After it reaches the ends of the element (200) in the proximity of the communication passages with the second chamber (600A), the heat transfer fluid passes into the second chamber (600A) and is conveyed again in the union.
  • the elements can be arranged as desired, since the arrangement is not constrained by the presence of the two conduits - the delivery and return conduits - thus permitting the construction of radiators of any shape.
  • each element (2, 20, 200) can be divided into the first and second chamber (6, 60, 600, 6A, 60A, 600A) by placing two separate elements with one chamber only in adjacent position, and not by means of a partition.
  • the union (3, 30, 300) can be obtained on the same side of the elements (2, 20, 200) or, alternatively, for instance on one side, on the opposite side or according to any arrangement, being possible to obtain circular radiators composed of a series of elements installed in series according to a circular, spiral, square, cubic, parallelepiped or similar shape.
