Definitions

  • the invention relates to a cooling element according to the preamble of claim 1.
  • Such cooling elements usually several connected to a cooling ceiling, used for the air conditioning of rooms.
  • GB 2 155 170 A shows a generic cooling or actually ventilation element with an approximately cuboid housing, which is completed against the room by a perforated plate with 28% hole portion and the interior of which forms an air chamber into which air is introduced through a pipe. Since the whole underside is used for the supply of air, it is not available for other purposes such as noise attenuation or only with severe restrictions resulting from the primary cooling function.
  • a cooling element is known, the housing of which is an air chamber, into which air is introduced via a pre-chamber cooling air that is permeable to air.
  • the air chamber is terminated by a micro-aperture cooling wall engaging the entire underside of the housing. Again, so the entire bottom is used for the supply of air.
  • a cooling element which comprises on carriers suspended parallel lines for cooling fluid, each with a rail, on the flat bottom magnetic strips are arranged, which hold a forming the underside of the cooling element plate, which is thermally coupled to the lines. Supply of air is not provided.
  • the invention is based on the object to provide a cooling element that both the air conditioning of a room, especially by supplying cooling air, serves as well as for other purposes such. Noise attenuation can be used.
  • cooling element In the cooling element according to the invention, only a part of the underside delimited as a cooling region is connected to an air chamber and is used to supply cooling air. This is usually sufficient for an adequate supply of fresh air, especially if several cooling elements form a cooling ceiling occupying the entire ceiling.
  • the cooling requirement can be covered in many cases solely by the cooling air supply, especially since the remaining portion of the cooling element down final hole plate can be cooled by thermally conductive coupling to the air chamber or in addition by cooling liquid leading lines, so he mainly by radiation exchange with the underlying Space contributes to its cooling.
  • the remaining area of the perforated plate which is separated from the air chamber substantially airtight, so that there is no cooling air flows, can be used without restriction for other purposes.
  • the perforated plate can there be covered with a sound-insulating mat made of fiber material or open-cell foam or other sound-absorbing material. But it can also be e.g. Loudspeaker can be arranged above the perforated plate.
  • the division between the cooling area and the remaining area can be adjusted according to the given needs.
  • the cooling element according to the invention comprises an approximately cuboid housing suspended at a small distance below a ceiling 1 with a downwardly open central part 2, on each side of which a side part 3a, b connects, which is also open at the bottom.
  • the upper part of the middle part 2 forms a flat horizontal ceiling 4, to which perpendicular to the bottom bending side walls 5a, b connect.
  • Each of the side parts 3a, b likewise has a ceiling with a planar ceiling area 6 adjoining the ceiling 4 in the same plane, on the inner edge of which a side wall 7 resting against the side wall 5a, b is bent vertically downwards, and an edge area adjoining the outer edge 8 u-shaped cross-section, which in a vertically upstanding edge strip 9, which does not quite reach the height of the ceiling 4, expires.
  • the side walls 5a, b of the middle part 2 are with the adjacent side walls 7 of the side parts 3a, b, each slightly above the lower edges of the side walls 5a, b turn outwards and form there horizontal anchor strips 10, screwed.
  • the anchor strips 10 are each bent downwards at the edge.
  • the middle part 2 and the side parts 3a, b are profiles made of sheet steel with over the length of substantially constant cross-section.
  • a pan 11 made of sheet steel comprises a flat perforated plate 12, which forms its bottom. It is provided with, for example, in a regular square 5mm grid arranged round holes 13 (Fig. 4, 5) with a diameter of about 2.5mm and has a hole content of about 20%.
  • the tub 11 also includes from the perforated plate 12 vertically upwardly bent side walls 14, to the upper edge connect inwardly projecting retaining strips 15, which rest for fastening the trough 11 on the edges of the edge strips 9 of the side parts 3a, b.
  • the trough 11 also has end walls 16, which may be interrupted substantially continuously or by an opening 17 located between the side walls 5a, b of the central part 2 for connection to a subsequent further cooling element.
  • each have a longitudinally continuous magnetic strip 18 is arranged rectangular cross section, which is in contact with the underside of one as with the top of the other and with little play between an adjoining the lower edge edge strip on the outside the side wall 5a, b of the middle part 2 and a corresponding edge strip of the anchor bar 10 is located.
  • a cooling wall 19 is arranged directly above the perforated plate 12, which fills the entire lying between the side walls 5 a, b and the end walls 16 rectangular area.
  • the cooling wall 19, which may rest directly on the perforated plate 12 or may be slightly spaced from it, consists of powder-coated steel sheet of, for example, 0.62 mm thickness with high heat conductivity at the underside to achieve a high absorption coefficient. It has micro-openings 20 (Fig. 4, 5) of at most 0.8 mm, preferably at most 0.6 mm and a total hole proportion of at most 2%, preferably at most 1% and is thus limited permeable to air.
  • the micro-openings 20 are arranged so that each of them lies above one of the holes 13 of the underlying perforated plate 12 and is not covered.
  • the top 4 of the air chamber 21 closing blanket 4 has a plurality of central, in the longitudinal direction at a distance successive air outlets 22, through which some air exits. It produces a laterally over the ceiling 4 and further on the top of the cooling element grazing flow, which prevents dust deposits and also causes a convective cooling of the ceiling 1.
  • the continuous magnetic strip 18 in each case firmly adheres to the anchor strip 10 and the side wall 5a, b and pulls the perforated plate 12 firmly against its underside and the lower edges of the side wall 5a, b, since the components involved consist entirely of ferromagnetic material.
  • the conduit 26 is thermally coupled by thermal conduction closely with the corresponding side part 3a, b and indirectly also with the perforated plate 12 so that they both for cooling the ceiling 1 - especially by radiation exchange - as well as on the perforated plate 12, especially the remaining area 25th the same contributes to the radiation cooling of the room.
  • the side chambers 23a, b are partially covered with fiberboard 29 or other sound deadening material, e.g. Mats made of open-pored foam filled. It can also be provided directly resting on the perforated plate 12 acoustic fleece.
  • fiberboard 29 or other sound deadening material e.g. Mats made of open-pored foam filled. It can also be provided directly resting on the perforated plate 12 acoustic fleece.
  • the cooling air flows from the air chamber 21 only through the cooling wall 19 to the cooling region 24 of the perforated plate 12 and through the same in the underlying space. This flow is controlled and limited by the cooling wall 19 with its relatively small free cross-section, so that no disturbing compact cold air flows and turbulence occur.
  • the perforated plate can also have a larger or smaller hole portion than described, but a hole proportion of at least 10% is preferred.
  • the hole portion of the cooling wall 19 can also be chosen differently than specified in the circumstances also, the cooling wall can be replaced by an air-permeable wall other types such as a fabric or non-woven or other air flow-restricting means.
  • the partitions may be connected in other ways with the perforated plate 12, but is given a magnetic connection before, for example, an adhesive compound preference.
  • individual magnets can be used and the airtight seal can be made in other ways, for example by seals made of rubber or plastic.
  • the use of magnetic strips facilitates installation and ensures high reliability and durability.
