Definitions

  • the first rectilinear part extends over a portion of the first profile corresponding to a length, measured in a direction perpendicular to the direction of alignment of the ducts and to a longitudinal direction of the ducts, that is greater than or equal to 30 mm, preferably greater than or equal to 40 mm, and/or less than or equal to 50 mm;
  • the distance between the second rectilinear part of the first profile and the rectilinear part of the second profile is greater than or equal to 2 mm and/or less than or equal to 10 mm, preferably less than or equal to 5 mm;
  • the ventilation device further comprises a third tube, such that the second profile of the second tube faces the second profile of the third tube, the distance between the center of the geometric section of the second tube and the center of the geometric section of the third tube preferably being less than the distance between the center of the geometric section of the first tube and the center of the geometric section of the tube; and
  • FIG. 7 schematically depicts a superposition of views in section on planes A-A and B-B of FIG. 6 ;
  • the row of ventilation tubes 8 may be arranged at a distance less than or equal to 150 mm from the row of heat-transfer tubes 4 , preferably less than or equal to 100 mm This distance is preferably greater than or equal to 5 mm, preferably greater than 40 mm This is because too short a distance between the ventilation tubes 8 and the heat-transfer tubes 4 carries the risk of not allowing uniform mixing of the flow of air ejected from the ventilation tubes 8 with the induced flow of air.
  • the impeller 102 comprises a plurality of blades 110 (or vanes) distributed in stages 112 along the longitudinal axis L 102 of the impeller 102 .
  • the longitudinal axis L 102 of the impeller corresponds to its axis of rotation when driven by the motor of the fan 100 .
  • the impeller 102 comprises thirteen stages 112 of blades 110 . Of course, this number of stages 112 is nonlimiting.
  • the openings 16 consist of slots made in the wall 17 of the ventilation tube 8 , these slots 16 extending in the direction of elongation of the ventilation tube 8 .
  • This slotted shape makes it possible to form an air passage of large dimensions, while at the same time maintaining satisfactory structural integrity of the ventilation tubes 8 .
  • the openings 16 extend over a large proportion of the length of the ventilation tube 8 , preferably over a total length corresponding to at least 90% of the length of the ventilation tube 8 .
  • the aerodynamic tube 8 illustrated in FIGS. 10 to 12 also comprises at least one opening 40 for ejecting a flow of air passing along the aerodynamic tube 8 , outside the aerodynamic tube 8 and outside the air inlet header 12 , notably substantially toward the heat exchanger 1 .
  • the opening or each opening 40 is, for example, a slot in an external wall 41 of the aerodynamic tube 8 , the slot or slots extending for example in the direction of elongation of the aerodynamic tube 8 in which they are made.
  • the total length of the opening 40 or of the openings may be greater than 90% of the length of the aerodynamic tube.
  • Each opening 40 is distinct from the ends of the aerodynamic tube 8 , via which ends the aerodynamic tube 8 opens into an air header 12 .
  • Each opening 40 is also outside of the air inlet header 12 .
  • the slotted shape makes it possible to form a large-sized air passage toward the heat exchanger 1 without excessively reducing the mechanical strength of the aerodynamic tubes 8 .
  • the distance f separating the second rectilinear part 38 a of the first profile 42 and the portion 38 b of the rectilinear part 48 of the second profile 44 that faces it may, however, be less than the distance separating the first longitudinal wall and the second longitudinal wall of the heat-transfer tube facing which the aerodynamic tube 8 is positioned.
  • the openings 40 are analogous to those of the example of FIG. 12 .
  • the distance e separating the internal 40 b and external 40 a lips of each opening 40 can be greater than or equal to 0.3 mm, preferably greater than or equal to 0.5 mm, more preferably greater than or equal to 0.7 mm, and/or less than or equal to 2 mm, preferably less than or equal to 1.5 mm, more preferably less than or equal to 0.9 mm, and even more preferably less than or equal to 0.7 mm.
