Definitions

  • the invention relates to a plate-shaped element provided with holes for the passage of air having a curved course in cross-section, thus forming two edges, and a corrugated course in longitudinal section, the element being intended to rest with its edges on the floor of a building so as to form an air duct.
  • Such elements usually placed on the floor in a storage room, in such a manner that several such ducts, which can be built up from sections, are thereby arranged at some distance of and parallel to each other.
  • Products to be dried, cooled and/or ventilated can then be brought into the storage room such, that said products are deposited in a heap above and between the air ducts.
  • air can be supplied to the air ducts continuously or intermittently, which air, whether or not heated, can escape from the air duct via the passages in the plate-shaped element and stream along the products to be treated.
  • the plate-shaped element is characterized in, that the holes are slotted holes, which are provided only in the tops of the corrugations in those portions of the plate-shaped element which join the edges of said plate-shaped element.
  • Fig. 1 illustrates a few air ducts 2 located adjacent to each other on a bottom 1, which ducts have been arranged parallel to each other.
  • the air ducts have, in cross section, curved, usually semicircular shape, whilst seen in longitudinal section an air duct has a corrugated course.
  • the ducts are thereby made of metal sheet, but of course it will be conceivable to use other materials for this purpose, such as e.g. plastic material.
  • An air duct can be made of a single plate-shaped part, but in particular with longer air ducts a duct will usually be built up from sections which overlap each other at their ends.
  • Such an air duct or a section of an air duct can be formed by bending a corrugated sheet 3 as illustrated in figs. 3 and 4 around its longitudinal axis extending parallel to its boundary edges 4 and 5.
  • slotted holes 7 have been provided in the tops 6 of the corrugations in the portions of the corrugated sheet joining the boundary edges 4 and 5 in such a manner that the longitudinal axes of said slotted holes coincide with the longitudinal axes of the corrugations and are therefore perpendicular to the boundary edges 4 and 5.
  • no holes have been provided, as will be apparent from figs. 3 and 4.
  • the slotted holes 7 located nearest to the boundary edges 4 and 5 lie in a line in the corrugation tops 6 located adjacent to each other, whilst the slotted holes located further away from the boundary edges 4 and 5 in a pair of adjacent corrugation tops 6, seen in the longitudinal direction of the boundary edges 4 and 5, are staggered relatively to each other. As a result of this a better spreading of the air coming out of the air duct via the slotted holes is achieved as well as a better resistance of the air duct to collapsing.
  • the centre distance between a pair of rectangular slotted holes located in a corrugation top 6 will preferably be ⁇ 130 mm, except for those slotted holes which have been arranged comparatively, closely together near the secondary edges 4 and 5 as is illustrated in the figures and whereby the centre distance between said slotted holes is 65 mm.
  • Fig. 5 shows a development of a plate-shaped portion, which can be used for making air ducts with smaller diameters e.g. between ⁇ 630 mm and 1025 mm.
  • the centre distance between the slotted holes which for the rest have the same. length as in the first mentioned embodiment, has thereby been chosen smaller and is preferbaly 90 mm here.
  • the centre distance between the slotted holes arranged closely together near the boundary lines 4 and 5 has thereby been kept equal to that of the embodiment discussed first.
  • the width of the strip of the sheet joining a boundary edge 4 or 5 measured in the direction of the corrugations is preferably less than 1/20 of the width of the developed sheet illustrated in figs. 3 and 5 measured between the boundary edges 4 and 5.
