Definitions

  • the present invention relates to a linear ventilation unit, in particular for a technical compartment.
  • the invention is aimed at any closed compartment, containing material capable of dissipating calories.
  • the present invention aims to remedy these drawbacks.
  • a ventilation unit in particular for a technical compartment, characterized in that it comprises two ventilation turbines with double tangential flow, arranged in parallel on the same plane inside a flat casing whose height roughly corresponds to the diameter of the turbines and which has air inlet and outlet openings formed longitudinally on its opposite faces.
  • Such a unit not only has the advantage of being compact but also of offering greater ventilation power than the various small fans usually used, but for a reduced size and excellent accommodation.
  • the ventilation unit designated as a whole by the reference 1 comprises a flat casing 2, generally parallelepipedic in which are housed two linear ventilation turbines called tangential flow 3 and 4.
  • the ventilation turbines are arranged parallel on the same plane, side by side, inside the flat casing 2.
  • the height H of the latter corresponds substantially to the diameter of the turbines 3 and 4.
  • the height H of the casing 2 is 43 mm.
  • the casing has a width L of 119 mm and the turbines 3 and 4 housed inside are symmetrically spaced at a center distance E of 60 mm.
  • the air intake A into the casing 2 takes place under the combined effect of the linear turbines 3 and 4 by a central longitudinal opening 5, formed on a lower face 6 of said casing 2.
  • the lateral edges 7, 8 respectively constitute one of the ends of two tangential linear deflectors 9, 10 in the form of scrolls, arranged laterally in the casing 2 on either side of said central opening 5 and partially enveloping the linear turbines 3, 4, to direct the air flow generated by each of them towards two spaced air outlet openings 11 and 12 in the form of rectangular longitudinal slots formed on an upper face 13 of the casing 2.
  • the mouths 11 and 12 are parallel to each other.
  • Their respective external lateral edges 14 and 15 constitute the other ends of the tangential volutes 9 and 10.
  • the turbines 3, 4 are driven by a ventilation unit thus formed by means of two electric motors 16, 17 connected by electric wires 18, 19 to a power supply.
  • the motors 16, 17 are of the same power and controlled in the same direction of rotation and form with the turbines 3, 4 independent and identical self-driving assemblies.
  • the electric motors 16, 17 of the linear turbines 3, 4 are arranged outside the casing 2, on two end walls 20, 21 thereof, each of these walls being perpendicular both to the plane in which the turbines 3, 4 are located and to their longitudinal axis.
  • Each of the walls 20, 21 comprises a coupling and a bearing (not visible).
  • the coupling is intended for one of the drive motors 16 or 17 of one of the turbines 3 or 4 and the opposite bearing is intended for the free end 22 or 23 of a support shaft of the other turbine 3 or 4, mounted opposite the first.
  • the walls 20, 21 forming a bearing are produced in two offset planes 24, 25 parallel to each other to form a re-entrant shoulder 26, capable of constituting a housing for each motor 16, 17 so that they fit into a substantially parallelepiped volume.
  • the air outlet vents 11, 12, produced on the upper face 13 of the casing 2 are offset longitudinally with respect to one another to be located at the vertical to the turbines 3, 4 mounted head to tail and facing only these.
  • the casing 2 is extended at its ends by two transverse tabs 27, 28 perforated by fixing holes 29, 30, 31, 32 executed at their respective angles to allow it to be placed in two parallel bars or slides 33, 34 of a compartment located in the lower part of a semi-closed enclosure.
  • the air outlet vents 11 and 12 are bordered longitudinally, each on the side opposite that of the upper limit of each volute, by a linear shape 35, 36 projecting downward, for example in the manner of a gutter, intended to avoid turbulence in the air flow.
  • the compartment is a cabinet 37 having a lower part 38 in which is housed the ventilation unit according to the invention in an approximate central position.
  • This cabinet has superimposed shelves such as 39 supporting drawers 40 or baskets 41 furnished with cards such as 42 or 43 representing as many electronic circuits formed of active components dissipating calories that must be removed.
  • the ventilation unit according to the invention represents the ideal solution for this type of assembly.
