Description

Dispositif d'évacuation de reau de condensation formée dans une
enceinte fermée non pressue# et enceinte pourvue d'un tel dispositif
La présente invention concerne un dispositif d'évacuation de l'eau de condensation formée dans une enceinte fermée, non pressurisée, renfermant de l'air ambiant chargé d'humidité.
Device for discharging condensed water formed in a
closed enclosure not pressed # and enclosure provided with such a device
The present invention relates to a device for discharging the condensation water formed in a closed, non-pressurized enclosure, containing ambient air charged with humidity.

L'invention s'applique très avantageusement, bien que de façon non limitative, au domaine des antennes et des radars, notamment aux enceintes pour balises, joints tournants d'antenne, etc. The invention applies very advantageously, although in a nonlimiting manner, to the field of antennas and radars, in particular to enclosures for beacons, rotating antenna joints, etc.

En effet, ces enceintes, lorsqu'elles sont refermées, contiennent un air ambiant chargé d'humidité qui, sous l'effet des variations de température va provoquer au-dessous du point de rosée une condensation d'eau liquide sur les parois intérieures, froides, de l'enceinte. In fact, these enclosures, when they are closed, contain ambient air charged with humidity which, under the effect of temperature variations will cause condensation of liquid water on the interior walls below the dew point, cold, from the enclosure.

Le ruissellement de l'eau condensée va provoquer en partie basse de l'enceinte une accumulation de liquide, pouvant représenter dans certains cas plusieurs litres d'eau, susceptible de détruire ou d'endommager le matériel installé à l'intérieur de l'enceinte. The runoff of condensed water will cause in the lower part of the enclosure an accumulation of liquid, which can represent in some cases several liters of water, capable of destroying or damaging the equipment installed inside the enclosure .

Pour éviter ces inconvénients, plusieurs solutions ont déjà été proposées, mais aucune ne s'est révélée pleinement satisfaisante. To avoid these drawbacks, several solutions have already been proposed, but none has proven fully satisfactory.

Une première possibilité consiste à utiliser, de façon bien connue, des sacs de déshydratant placés à l'intérieur de l'enceinte. Ces sacs sont certes très efficaces, mais leur volume est toujours relativement important si l'on souhaite pouvoir absorber une quantité d'eau relativement élevée. En outre, à saturation, ces sacs doivent être remplacés, et ce d'autant plus souvent qu'ils sont de petit volume. En variante, pour faciliter le remplacement, on peut utiliser des bouchons déshydrateurs, qui ont un effet identique à celui des sacs déshydratants, mais sont de volume plus réduit et de coût plus élevé. A first possibility consists in using, in a well known manner, bags of desiccant placed inside the enclosure. These bags are certainly very effective, but their volume is always relatively large if one wishes to be able to absorb a relatively large amount of water. In addition, when saturated, these bags must be replaced, all the more often as they are small. As a variant, to facilitate replacement, it is possible to use dehydrating plugs, which have an effect identical to that of desiccant bags, but are of smaller volume and of higher cost.

On notera que le remplacement des sacs ou bouchons déshydratants est souvent assez malcommode, les matériels tels que les boîtiers d'antennes ou radars secondaires étant souvent situés en hauteur et très peu accessibles. It will be noted that the replacement of desiccant bags or plugs is often rather inconvenient, equipment such as antenna boxes or secondary radars often being located high up and very inaccessible.

Une autre solution consiste à prévoir, de façon très simple, des trous de mise à l'air libre. Ce procédé est bien sûr le moins coûteux, mais a l'inconvient de ne pas protéger l'enceinte à l'encontre de l'introduction d'insectes et de poussières. Another solution is to provide, in a very simple way, air vent holes. This process is of course the least expensive, but has the drawback of not protecting the enclosure against the introduction of insects and dust.

La présente invention permet de pallier ces inconvénients et de supprimer le risque d'accumulation d'eau dans les parties basses des enceintes fermées non pressurisées.  The present invention overcomes these drawbacks and eliminates the risk of water accumulation in the lower parts of closed non-pressurized enclosures.

A cet effet, selon l'invention, le dispositif d'évacuation de l'eau de condensation comprend, au point le plus bas de l'enceinte, un orifice tourné vers le bas faisant communiquer le volume intérieur de l'enceinte
avec l'environnement extérieur et fermé par un obturateur en matériau capillaire, de manière à drainer hors de l'enceinte l'eau de condensation recueillie en partie basse de celle-ci.
To this end, according to the invention, the device for discharging the condensation water comprises, at the lowest point of the enclosure, an orifice facing downwards making the interior volume of the enclosure communicate.
with the external environment and closed by a shutter of capillary material, so as to drain out of the enclosure the condensation water collected in the lower part thereof.

Par "matériau capillaire", on entendra un matériau qui, quelle que soit sa texture, soit perméable à l'eau et draine celle-ci par capillarité (effet de mèche), et qui d'autre part ait une texture suffisamment serrée pour empêcher les insectes et les poussières de pénétrer à l'intérieur de l enceinte (effet de filtrage). By "capillary material" is meant a material which, whatever its texture, is permeable to water and drains it by capillarity (wicking effect), and which on the other hand has a sufficiently tight texture to prevent insects and dust from entering the interior of the enclosure (filtering effect).

Ce matériau capillaire peut être par exemple constitué d'un tissu ou
d'un feutre un peu épais #(pour des raisons de solidité mécanique).
This capillary material can for example consist of a fabric or
a slightly thick felt # (for reasons of mechanical strength).

En particulier, le feutre est avantageux pour plusieurs raisons:
- il a la propriété de faire mèche, ce qui permet de capter l'eau de
condensation et de l'évacuer au goutte à goutte vers l'extérieur,
- il conserve cette propriété même si, dans le temps, un dépôt gras
venait à se réaliser sur l'une ou l'autre de ses faces,
- il permet à l'air d'être filtré efficacement des poussières et des
insectes,
~il est d'un prix extrêmement faible et peut être changé très
facilement,
- il est facile à emboutir et les rondelles obtenues présentent un
maintien mécanique satisfaisant, ce qui permet de monter
directement la rondelle dans le logement qui lui est réservé sur la
paroi de l'enceinte, sans besoin d'un support intermédiaire.
In particular, felt is advantageous for several reasons:
- it has the property of wicking, which makes it possible to collect water from
condensation and drip it to the outside,
- it retains this property even if, over time, a fatty deposit
came to be realized on one or the other of its faces,
- it allows air to be effectively filtered from dust and
insects,
~ it is extremely low cost and can be changed very
easily,
- it is easy to stamp and the resulting washers have a
satisfactory mechanical support, which allows mounting
the washer directly into the housing reserved for it on the
enclosure wall, without the need for an intermediate support.

On va maintenant donner deux exemples de réalisation du dispositif selon la présente invention, en référence aux dessins annexés sur lesquels
- la figure 1 montre un premier mode de réalisation du dispositif de la
présente invention, et
- la figure 2 montre un second mode de réalisation du dispositif de la
présente invention.
We will now give two embodiments of the device according to the present invention, with reference to the accompanying drawings in which
- Figure 1 shows a first embodiment of the device of the
present invention, and
- Figure 2 shows a second embodiment of the device of the
present invention.

Sur la figure 1, la référence 1 désigne la paroi latérale de l'enceinte fermée (par exemple un boîtier de joint tournant d'antenne), cette enceinte étant close en partie inférieure par un carter 2. In FIG. 1, the reference 1 designates the side wall of the closed enclosure (for example an antenna rotating joint housing), this enclosure being closed in the lower part by a casing 2.

Le point le plus bas de ce carter 2 est percé d'un orifice 3 débouchant vers l'extérieur et assurant la mise en communication du volume intérieur de l'enceinte I avec l'environnement extérieur ambiant. The lowest point of this casing 2 is pierced with an orifice 3 opening towards the outside and ensuring the communication of the interior volume of the enclosure I with the ambient external environment.

Cet orifice 3 est obturé par une rondelle en feutre 4 reposant contre un épaulement 5 et serrée contre celui-ci par un bouchon de fermeture 6, par exemple vissé dans la paroi du carter 2. Le bouchon 6 est pourvu d'un trou traversant 7 permettant d'évacuer vers l'extérieur l'eau de condensation ayant traversé la rondelle 4 ; de préférence, la paroi 8 qui aboutit à cet orifice 7 est conique pour faciliter l'écoulement de cet eau de ruissellement. This orifice 3 is closed by a felt washer 4 resting against a shoulder 5 and tightened against the latter by a closure plug 6, for example screwed into the wall of the casing 2. The plug 6 is provided with a through hole 7 allowing the condensed water having passed through the washer 4 to be removed to the outside; preferably, the wall 8 which terminates at this orifice 7 is conical to facilitate the flow of this runoff water.

Une autre variante, moins coûteuse à mettre en oeuvre mais tout aussi efficace, est illustrée figure 2. Another variant, less costly to implement but just as effective, is illustrated in FIG. 2.

Dans ce mode de réalisation, l'orifice 3 présente une paroi intérieure 9 rétrécie vers le bas, par exemple conique, de manière à former cône de serrage pour la rondelle de feutre 4, dont l'épaisseur est choisie de manière à lui assurer un maintien propre. In this embodiment, the orifice 3 has an inner wall 9 narrowed downwards, for example conical, so as to form a tightening cone for the felt washer 4, the thickness of which is chosen so as to provide it with a keeping clean.

Une fois mise en place, la rondelle 3 est immobilisée par un congé ou par des points de colle 10, par exemple une colle époxy ou polyuréthane, ou un mastic polymérisable. Once in place, the washer 3 is immobilized by a leave or by dots of adhesive 10, for example an epoxy or polyurethane adhesive, or a polymerizable mastic.

Les dimensions (épaisseur, diamètre) ainsi que la texture de la rondelle de feutre ne sont pas des paramètres critiques pour la mise en oeuvre de l'invention ; en ce qui concerne l'épaisseur, la dimension dépend essentiellement de la rigidité mécanique voulue (plus élevée dans le mode de réalisation de la figure 2 que dans celui de la figure 1, et plus élevée pour un diamètre important), tandis que le diamètre de la rondelle dépend principalement de l'encombrement voulu pour le dispositif d'évacuation et, subsidiairement, de la quantité d'eau à évacuer.  The dimensions (thickness, diameter) as well as the texture of the felt washer are not critical parameters for the implementation of the invention; as regards the thickness, the dimension essentially depends on the desired mechanical rigidity (higher in the embodiment of FIG. 2 than in that of FIG. 1, and higher for a large diameter), while the diameter of the washer depends mainly on the size desired for the evacuation device and, alternatively, on the amount of water to be evacuated.
