Abstract
Description
La présente invention concerne un dispositif de protection active contre le gel par apport de calories souterraines. Le domaine d'application concerne particulierement les petits volumes pleins d'eau tels que robinets de puisage aériens, vannes, compteurs, pompes, installés ou non. The present invention relates to a device for active protection against freezing by supplying underground calories. The field of application particularly concerns small volumes full of water such as overhead taps, valves, meters, pumps, installed or not.
Traditionnellement la protection contre le gel se fait par apport de cale- ries d'origine électrique, ou vidange des volumes exposés, ou isolation thermique. Dans les deux derniers cas l'utilisation des appareils protégés est retardée par des manipulations supplémentaires, parfois conpliquées et astreignantes. Traditionally, frost protection is provided by the addition of electrical heating blocks, or emptying exposed volumes, or thermal insulation. In the last two cases, the use of protected devices is delayed by additional manipulations, sometimes complicated and exacting.
La protection par vidange impose une autre vidange. la protection par iso- lation thermique impose un déshabillage de certaines parties pour en avoir l'acces. Dans la version aérienne des robinets de puisage seul le rapport entre l'iner- tie thermique du matériel employé et la qualité de l'isolation permet de présumer de la protectio#btenue. Ceci explique que les longues périodes de gel viennent à bout de ce te de protection. Les limites de ce tyoe de protection reculent avec l'emploi de matériels semi enterrés ou enterres. The drain protection requires another drain. protection by thermal insulation requires undressing of certain parts in order to have access to them. In the aerial version of draw-off taps, only the relationship between the thermal inertia of the equipment used and the quality of the insulation makes it possible to presume the protection provided. This explains that the long periods of frost overcome this protective te. The limits of this type of protection go back with the use of semi buried or buried materials.
La p résente invention a pour objet de remédier à ces poblèmes tout en permettant une utilisation immédiate quelles que soient les conditions climatiques. The object of the present invention is to remedy these problems while allowing immediate use whatever the climatic conditions.
Elle consiste à utiliser des tubes de chaleur appelés aussi caloducs pour prélever la chaleur souterraine toujours disponible et la transmettre aux parties exposées. Le fonctionnement du caloduc est spontané et provoque un transfert de calories vers tous ses élé@ments de surface plus froids que le bousilleur. La quantité de c@aleur transportée est proportionnelle aux différences de température,
Dans une forme préférentielle, la présente invention consiste, à la fabrication, à incorporer un tube de chaleur, muni d'un système de répartition de ruissellement des condensats, à une colonne montante desservant un robinet de puisage.It consists in using heat tubes also called heat pipes to take the always available underground heat and transmit it to the exposed parts. The operation of the heat pipe is spontaneous and causes a transfer of calories to all of its cooler surface elements than the boiler. The quantity of heat transported is proportional to the temperature differences,
In a preferred form, the present invention consists, during manufacture, in incorporating a heat tube, provided with a system for distributing the drainage of condensates, into a riser serving a tap.
L'extrémité supérieure du cal due est immergée et le plus près possible de la cham- bre d'eau du robinet. la parte inférieure du caloduc traverse la pièce de raccoz- dement de la colonne à la ligne d'alimentationet s'enfonce dans le sol à une profondeur où la température est toujours régulière et positive la protection se fait par conduction thermique dens l'eau et les autres mat@riaux en présence. Les dimensions de l'ens@mble sont tributaires de la zone climatique, de la température et de la nature du sol, une gamme de matériel étant prévue pour différents degrés de protection. The upper end of the cal due is submerged and as close as possible to the chamber of tap water. the lower part of the heat pipe crosses the connection piece from the column to the supply line and sinks into the ground at a depth where the temperature is always regular and positive the protection is done by thermal conduction in water and the other materials involved. The dimensions of the set are dependent on the climatic zone, the temperature and the nature of the soil, a range of equipment being provided for different degrees of protection.
Dans une forme moins courante destinée à la protection de matériels déjà implantés, le dispositif se présente sus la forme d'un raccord supérieur destiné à remplacer le coude existent, ce coude étant venu d fonderie et comportant un logement prévu pour recevoir l'extrémité supérieure du caloduc. La colonne d'ali
tentation est alors protégée par contact thermique avec le caloduc qui s' enfonce ensuite sous terre. Ce contact est obtenu par l'emploi de pâtes thermiques du commerce et par enroulement serré d'un feuillard de cuivre autour du caloduc et de la colonne montante. In a less common form intended for the protection of materials already implanted, the device comes in the form of an upper connector intended to replace the existing elbow, this elbow having come from the foundry and comprising a housing provided for receiving the upper end of the heat pipe. Ali's column
temptation is then protected by thermal contact with the heat pipe which then sinks underground. This contact is obtained by the use of commercial thermal pastes and by tight winding of a copper strip around the heat pipe and the riser.
Le prototype réalisé se présente sous la forme d'une colonne montante en tube cuivre de 2 cm de diamètre utile et 120 cm de longueur. la ligne d'ali- mentation est à 40 cm de profondeur. Le caloduc traverse la pièce de raccordement inférieure et s'enfonce de 160 cm sous la ligne d'alimentation. La partie supérieure du caloduc dépasse le coude d'arrivée au robinet de 2 cm. Le caloduc est formé d'un tube de cuivre recuit de 1cm de diamètre utile contenant 20 ini de fluide fluorocarboné à hante tension de vapeur. Une hélice en fil d'acier plaquée sur la paroi intérieure est destinée à mouiller toute la surface enterrée. The prototype produced is in the form of a riser made of copper tube with a useful diameter of 2 cm and a length of 120 cm. the supply line is 40 cm deep. The heat pipe crosses the lower connection piece and sinks 160 cm below the supply line. The upper part of the heat pipe exceeds the inlet elbow at the tap by 2 cm. The heat pipe is made of an annealed copper tube 1 cm in useful diameter containing 20 ini of fluorocarbon fluid with haunting vapor pressure. A steel wire propeller pressed against the interior wall is intended to wet the entire buried surface.
Le trou où est enfoncé le caloduc est percé avec une tige métallique, puis apres introduction du caloduc est rempli à refus d'un mélange capillaire composé de deux parties égales, l'une de charbon de bois finement pilé au mor- tier et mélangée à l'autre, de sable fin de rivière ou de mer. Le tout est arrosé d'eau pour obtenir un tassement définitif. Un congélateur domestique dont le fona est percé est enfilé autour de l'ensemble. The hole where the heat pipe is inserted is drilled with a metal rod, then after introduction of the heat pipe is filled with refusal of a capillary mixture composed of two equal parts, one of charcoal finely pounded in the mortar and mixed with the other, of fine river or sea sand. The whole is watered to obtain a final settlement. A domestic freezer whose fona is pierced is threaded around the whole.
L'essai fait constater une température au robinet de +6,20c, l'ambiance du congélateur variant entre -24 et -32 C. The test shows a temperature at the tap of + 6.20c, the atmosphere of the freezer varying between -24 and -32 C.
