Abstract

The rubber insert may have metal reinforcement and is placed inside the pipe over the whole length exposed to the risk of freezing. It has a section adapted to the pipe section, e.g. circular, rectangular, semi-circular, and it is compressible to prevent the production of too great internal pressures during freezing. The insert has a series of longitudinal channel sections allowing the free flow of liq. with walls between them which are compressed as the liq. freezes. If the insert (2) is to be used in a solar collector, it is positioned with the metal tube (1) under the glass sheet (3).

Description

DESCRIPTION
La présente invention concerne un dispositif de protection permettant d'éviter les dégâts dûs au gel de liquides dans des tuyauteries ou éléments d'appareils faisant office de tuyauteries.DESCRIPTION
The present invention relates to a protective device for preventing damage due to the freezing of liquids in pipes or elements of apparatus acting as pipes.

Actuellement lorsqu'il y a risques de gel on protège les tuyauteries entrtautre, soit en les vidangeant soit en faisant circuler un liquide "antigel".  Currently when there is a risk of frost protection piping intertother, either by draining or circulating a liquid "antifreeze".

La vidange ne peut être une solution retenue lorsque l'on demande à l'appareillage un service permanent. Drainage can not be a solution chosen when a permanent service is required.

La circulation d'un liquide "antigel" nécessite un entretien plus suivi et complique souvent les circuits. The circulation of an "antifreeze" liquid requires more frequent maintenance and often complicates the circuits.

C'est notamment le cas pour la majorité des installations de chauffage pal- panneaux solaires à fluide caloporteur où un échangeur intermédiaire est alors indispensable.This is particularly the case for the majority of heating installations solar panels with heat transfer fluid where an intermediate exchanger is then essential.

La présente invention peut permettre l'utilisation directe de tuyauteries exposées aux intempéries sans p > 4cau- tions particulières.  The present invention may allow the direct use of piping exposed to the weather without particular peculiarities.

Le dispositif objet de l'invention comporte la mise en place dans la tuyauterie d'corps mort" de section et de compressibilité adaptée et ceci sur toute la longueur exposée aux risques de gel. The device object of the invention comprises the implementation in the pipe dead body "section and compressibility adapted and this over the entire length exposed to the risk of freezing.

Ce corps peut être de construction homogène ou non. This body can be of homogeneous construction or not.

A titre d'exemple non limitatif il peut être de caoutchouc, de caoutchouc de qualité alimentaire, avec des armatures métalliques ou non.By way of non-limiting example it may be rubber, food grade rubber, with metal reinforcements or not.

Sur la planche A annexée sont représentées à titre d'exemple non limitatif, différentes sections de tuyauteries
Figure 1 circulaire, figure 2 rectangulaire, figure 3 elliptique figure 8 quelconque. Le"corps mort" figure en partie hachurée.On the attached plate A are shown by way of non-limiting example, different sections of pipework
Figure 1 circular, Figure 2 rectangular, Figure 3 elliptical figure 8 any. The "dead body" is partly hatched.

I1 laisse dans la tuyauterie un passage libre repéré "section libre sufrisant pour la circulation du liquide sans trop de perte de charge. I1 leaves in the piping a free passage marked "free section sufrisant for the circulation of the liquid without too much loss of load.

Par sa configuration il empêche que le liquide s'il y a gel, puisse former un seul bloc rigide. By its configuration it prevents that the liquid if there is frost, can form a single rigid block.

Sur le dessinssà titre d'exemple non limitatif, nous aur-ions ainsi 4 blocs en lieu et place des 4 portions de "section libre". In the drawings, by way of non-limiting example, we will thus have 4 blocks in place of the 4 portions of "free section".

Lops mort" par sa compiessibilité évite l!obtention de pressions internes trop zle;ées lors de gels avec augmentation de volume.  Lops mort "by its compsibility avoids the obtaining of internal pressures too zle ées during gels with increase in volume.

Nous allons décrire à titre d'exemple non limitatif un mode de réalisation de capteur solaire à fluide caloporteur utilisant le dispositif objet de l'invention. We will describe by way of non-limiting example an embodiment of solar collector with heat transfer fluid using the device of the invention.

Actuellement ces capteurs solaires sont - soit entièrement métalliques avec circulation interne de
liquide antigel. Ils imposent un échangeur intermédiaire qui
complique l'installation.Currently these solar collectors are - either entirely metallic with internal circulation of
antifreeze liquid. They impose an intermediate interchange
complicates the installation.

D'autre part leur surface est souvent limitée par la technologie et le coût. On the other hand their surface is often limited by technology and cost.

- soit formés de plaques eu feuilles métalliques accouplées à
des tuyauteries souples. Ils ne craignent pas le gel et peuvent
être fabriqués en grande longueur mais n'ont pas un aussi bon rendement au niveau de la transmission calorifique "métal tuyauterie souple."
Tous demandent des aménagements d'implantation importants (coffrets étanches1 vitreries sans grande résistance mécanique).- formed of sheets with metal sheets coupled to
flexible pipes. They do not fear frost and can
be made in great length but do not have as good a performance in terms of heat transfer "flexible metal piping."
All require major implementation arrangements (sealed boxes1 glass without strong mechanical resistance).

Ajoutons que tous n ont pas une très bonne tenue à la pression interne et que pour d'autres la protection contre la corrosion atmosphérique n'est pas absolue.  Let us add that not all have a very good resistance to internal pressure and that for others the protection against atmospheric corrosion is not absolute.

De nouveaux capteurs solaires peuvent être construits en utilisant le dispositif précédemment décrit. New solar collectors can be built using the device previously described.

La planche B représente la vue "coupe" d'un tel capteur. The board B represents the "cut" view of such a sensor.

- repère 1 - ossature métallique du capteur réalisée à l'aide d'un profilé ayant un très bon coefficient de conduc tibilité thermique. (aluminium ou ses alliages par exemple). - reference 1 - metal frame of the sensor made using a profile having a very good coefficient of thermal conductivity. (aluminum or its alloys for example).

- repère 2 - "corps mort" de section et de compressibilité adaptées. - reference 2 - "dead body" section and compressibility adapted.

- repère 3 - pavés de verre pour la protection contre les déperditions par convection naturelle, de bonne résistance mécanique coulissant pour mise en place rapide. - mark 3 - glass pavers for protection against loss by natural convection, good sliding mechanical resistance for quick installation.

- repère h - joints d'étanchéité et de serrage. - mark h - seals and clamps.

- repère 5 - calorifuge de la partie inerte du capteur. - reference 5 - insulation of the inert part of the sensor.

Les avantages sont alors les suivants
- Très bon échange thermique au niveau "zone de captage liquide caloporteur.The advantages are then as follows
- Very good heat exchange at "liquid coolant collection zone.

- Installation simplifiée c'est à dire sans circuit antigel ni échangeur intermédiaire, travaillant directement sur la réserve d'eau à chauffer. - Simplified installation ie without antifreeze circuit or intermediate exchanger, working directly on the water supply to be heated.

- Très bonne tenue à la corrosion atmosphérigue.  - Very good resistance to atmospheric corrosion.

- Très bonne tenue à la pression interne.  - Very good resistance to internal pressure.

- Possibilité de fabrication en grande longueur avec bonne résistance mécanique. - Possibility of manufacturing in great length with good mechanical resistance.
