Description

Pavillon pour ventilateurPavilion for fan

L’invention concerne un pavillon pour un ventilateur qui comprend une canalisation d’entrée sensiblement cylindrique selon un premier axe. Ce pavillon est destiné à être disposé devant la canalisation d’entrée pour optimiser le flux d’air entrant dans le ventilateur.The invention relates to a bell for a fan which comprises a substantially cylindrical inlet channel along a first axis. This pavilion is intended to be placed in front of the inlet duct to optimize the flow of air entering the fan.

Il est connu d’utiliser un tel pavillon en entrée d’un ventilateur. Un tel pavillon comprend classiquement une bague sensiblement de révolution autour d’un deuxième axe confondu avec le premier axe lorsque le pavillon est en place en entrée du ventilateur.It is known to use such a horn at the inlet of a fan. Such a horn conventionally comprises a ring substantially of revolution around a second axis coinciding with the first axis when the horn is in place at the inlet of the fan.

Un tel pavillon présente préférentiellement une section transverse s’évasant à mesure que l’on s’éloigne du ventilateur. Ainsi le pavillon forme un entonnoir concentrant le flux d’air entrant dans la canalisation d’entrée. La section transverse est généralement continue. Elle peut être courbe, préférentiellement circulaire encore préférentiellement selon un quart de cercle. Selon un mode de réalisation, elle est parallèle au deuxième axe en partie proximale, à savoir au plus près du ventilateur et de sa canalisation d’entrée et perpendiculaire au deuxième axe en partie distale, à savoir au plus loin du ventilateur. Ainsi la partie proximale forme une première lèvre, sensiblement cylindrique selon le deuxième axe, de diamètre légèrement inférieur au diamètre de la canalisation d’entrée. Ainsi, lorsque le pavillon est en place à l’entrée du ventilateur, la première lèvre s’insère dans la canalisation d’entrée.Such a pavilion preferably has a cross section that widens as one moves away from the fan. Thus the pavilion forms a funnel concentrating the flow of air entering the inlet duct. The cross section is generally continuous. It can be curved, preferably circular, more preferably according to a quarter circle. According to one embodiment, it is parallel to the second axis in the proximal part, namely as close as possible to the fan and its inlet pipe and perpendicular to the second axis in the distal part, namely furthest from the fan. Thus the proximal part forms a first lip, substantially cylindrical along the second axis, with a diameter slightly smaller than the diameter of the inlet pipe. Thus, when the pavilion is in place at the inlet of the fan, the first lip is inserted into the inlet channel.

Il apparaît à l’étude, qu’une circulation parasite peut s’établir à l’interface entre le pavillon et la conduite d’entrée du ventilateur. Cette circulation parasite perturbe la circulation nominale tel que souhaitée, à savoir du pavillon vers la canalisation d’entrée du ventilateur, en laissant apparaître une circulation dérivée créée par une ré-aspiration de l’air en sortie du ventilateur et revenant à l’entrée du ventilateur en traversant l’interface entre le pavillon et la canalisation d’entrée.It appears from the study that parasitic circulation can be established at the interface between the roof and the fan inlet duct. This parasitic circulation disrupts the nominal circulation as desired, namely from the roof to the fan inlet pipe, by revealing a derivative circulation created by a re-suction of the air at the fan outlet and returning to the inlet. of the fan by crossing the interface between the pavilion and the inlet pipe.

Cette circulation parasite perturbe la circulation nominale et en réduit d’autant le débit utile.This parasitic circulation disrupts the nominal circulation and reduces the useful flow accordingly.

Aussi, il convient de pallier cette circulation parasite.Also, it is necessary to overcome this parasitic circulation.

Pour cela, l’invention a pour objet un pavillon, pour un ventilateur qui comprend une canalisation d’entrée sensiblement cylindrique selon un premier axe, lequel pavillon comprendFor this, the subject of the invention is a horn, for a fan which comprises a substantially cylindrical inlet duct along a first axis, which horn comprises

- une première bague sensiblement de révolution autour d’un deuxième axe sensiblement confondu avec le premier axe et présentant une section transverse courbe s’évasant en s’éloignant du ventilateur, sensiblement parallèle au deuxième axe en partie proximale et sensiblement perpendiculaire au deuxième axe en partie distale, la partie proximale formant une première lèvre sensiblement cylindrique selon le deuxième axe, de diamètre légèrement inférieur au diamètre de la canalisation d’entrée afin de pouvoir s’insérer dans la canalisation d’entrée, et- a first ring substantially of revolution around a second axis substantially coincident with the first axis and having a curved transverse section widening away from the fan, substantially parallel to the second axis in the proximal part and substantially perpendicular to the second axis in distal part, the proximal part forming a first substantially cylindrical lip along the second axis, of diameter slightly smaller than the diameter of the inlet pipe in order to be able to be inserted into the inlet pipe, and

- une deuxième bague sensiblement de révolution autour du deuxième axe, assemblée à la première bague de manière étanche, et formant une deuxième lèvre, sensiblement parallèle à la première lèvre, de diamètre légèrement supérieur au diamètre de la canalisation d’entrée afin de pouvoir coiffer la canalisation d’entrée.- a second ring substantially of revolution around the second axis, assembled to the first ring in a sealed manner, and forming a second lip, substantially parallel to the first lip, of diameter slightly greater than the diameter of the inlet pipe in order to be able to cover the inlet pipe.

Avantageusement, la première bague présente une section transverse circulaire, de préférence selon un quart de cercle.Advantageously, the first ring has a circular transverse section, preferably according to a quarter circle.

Avantageusement encore, la deuxième bague est cylindrique.Advantageously, the second ring is cylindrical.

Selon un deuxième aspect, l’invention concerne un ventilateur dont la canalisation d’entrée sensiblement cylindrique est associée à un pavillon tel que décrit précédemment.According to a second aspect, the invention relates to a fan whose substantially cylindrical inlet pipe is associated with a roof as described above.

Selon un troisième objet, l’invention concerne un dispositif d’épuration d’air, de préférence par plasma à froid, comprenant au moins un ventilateur et un tel pavillon, disposé sur la canalisation d’entrée dudit au moins un ventilateur.According to a third object, the invention relates to an air purification device, preferably by cold plasma, comprising at least one fan and such a horn, arranged on the inlet pipe of said at least one fan.

L’invention sera mieux comprise à la lecture de la description qui suit, faite uniquement à titre d’exemple, et en référence aux figures en annexe dans lesquelles:The invention will be better understood on reading the following description, given solely by way of example, and with reference to the appended figures in which:
