Abstract
(EN)
This fan (10) comprises: a centrifugal fan (20); and a casing (40) having the centrifugal fan housed therein. The fan (10) comprises: an intake-side partition (50) which partitions a fluid suction passage (41) into a first suction passage (411) and a second suction passage (412); and an outlet-side partition (60) which partitions a fluid blowing passage (42) into a first blowing passage (421) and a second blowing passage (422). The casing includes a shroud-facing portion (44) which faces a shroud (24) of the centrifugal fan with a predetermined interval therebetween, and which forms a reverse flow passage (46) through which a first fluid and a second fluid flow from the fluid blowing passage between the shroud, towards the fluid suction passage. The reverse flow passage has a structure which curbs one of either the first fluid which flows through the first blowing passage or the second fluid which flows through the second blowing passage from flowing into the suction passage into which the other fluid is sucked, that being the other of the first suction passage and the second suction passage.

Le présent ventilateur (10) comprend : un ventilateur centrifuge (20) ; et un boîtier (40) ayant le ventilateur centrifuge logé à l'intérieur. Le ventilateur (10) comprend : une cloison côté admission (50) qui sépare un passage d'aspiration de fluide (41) en un premier passage d'aspiration (411) et un second passage d'aspiration (412) ; et une cloison côté sortie (60) qui sépare un passage de soufflage de fluide (42) en un premier passage de soufflage (421) et un second passage de soufflage (422). Le boîtier comprend une partie en vis-à-vis de l'enveloppe (44) qui fait face à une enveloppe (24) du ventilateur centrifuge avec un intervalle prédéterminé entre-deux, et qui forme un passage d'écoulement inverse (46) à travers lequel un premier fluide et un second écoulement de fluide provenant du passage de soufflage de fluide entre l'enveloppe, vers le passage d'aspiration de fluide. Le passage d'écoulement inverse a une structure qui arrête l'un ou l'autre du premier fluide qui s'écoule à travers le premier passage de soufflage ou du second fluide qui s'écoule à travers le second passage de soufflage de s'écouler dans le passage d'aspiration dans lequel l'autre fluide est aspiré, qui est l'autre parmi le premier passage d'aspiration et le second passage d'aspiration.
(JA)
送風機(10)は、遠心ファン(20)と、遠心ファンが内部に収容されるケーシング(40)と、を備える。送風機(10)は、流体吸込通路(41)を第1吸込通路(411)と第2吸込通路(412)とに仕切る入口側仕切部(50)と、流体吹出通路(42)を第1吹出通路(421)と第2吹出通路(422)とに仕切る出口側仕切部(60)と、を備える。ケーシングは、遠心ファンのシュラウド(24)に対して所定の隙間をあけて対向するとともに、シュラウドとの間に流体吹出通路から流体吸込通路に向けて第1流体および第2流体が流れる逆流通路(46)を形成するシュラウド対向部(44)を含んでいる。逆流通路は、第1吹出通路を流れる第1流体および第2吹出通路を流れる第2流体のうち一方の流体が、第1吸込通路および第2吸込通路のうち他方の流体が吸い込まれる吸込通路に流れることが抑制される構造になっている。
