Title
(EN) JET FAN AND VEHICLE COMPRISING SUCH A FAN
(FR) VENTILATEUR À JET ET VÉHICULE DOTÉ D'UN TEL VENTILATEUR
Abstract
(EN)
A fan (10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h) is described with a first conveying element (11), fluidly connectable with a source (120, 121, 123, 203, 405, 410, 412) of a primary air flow (F1) and defining a first passage (12) for the primary air flow (F1); a first mouth (19) receiving a first aliquot of the primary air flow (F1) from the first passage (12); a first Coanda surface (20) onto which the first mouth (19) directs the first aliquot; and a first opening (14) fluidly connected with the first mouth (19) and crossable by the first aliquot coming of the first mouth (19) and a secondary air flow (F2); the fan (10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h) comprises a second conveying element (30), fluidly connected with the first conveying element (11) and defining internally a second passage (32) for a second aliquot of the primary air flow (F1), and comprises: a second mouth (35) receiving the second aliquot from the second passage (32) and a second Coanda surface (36) onto which the second mouth (35) directs the second aliquot.
(FR)
L'invention concerne un ventilateur (10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h) comprenant un premier élément de transport (11), pouvant être relié de manière fluidique à une source (120, 121, 123, 203, 405, 410, 412) d'un écoulement d'air primaire (F1) et définissant un premier passage (12) pour l'écoulement d'air primaire (F1) ; un premier orifice (19) destiné à recevoir une première aliquote de l'écoulement d'air primaire (F1) à partir du premier passage (12) ; une première surface à effet Coanda (20) sur laquelle le premier orifice (19) dirige la première aliquote ; et une première ouverture (14) en liaison fluidique avec le premier orifice (19) et pouvant être croisée par la première aliquote en provenance du premier orifice (19) et par un écoulement d'air secondaire (F2). Le ventilateur (10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h) comprend un second élément de transport (30) relié de manière fluidique au premier élément de transport (11) et définissant intérieurement un second passage (32) pour une seconde aliquote de l'écoulement d'air primaire (F1). Ledit ventilateur comprend également : un second orifice (35) destiné à recevoir la seconde aliquote à partir du second passage (32), et une seconde surface à effet Coanda (36) sur laquelle le seconde orifice (35) dirige la seconde aliquote.
