Abstract

The device consists of a cylindrical body (1) whose ends may be connected to the ends of respective sections of an exhaust gas conduit by a simple push fit. A series of perforated fins (2) are stacked around the cylindrical body to diffuse heat from the body into an air flow passing around them.The cylindrical body and fins are enclosed in a cylindrical casing (3) to define a forced air flow over the fins. An inlet opening (5) is associated with a closed end plate of the casing for connection to a hot air extraction system. Air enters the other end of the casing via a filter element (4).

Description

Ma présente invention concerne un dispositif pour récupérer la chaleur d'un tuyau d'évacuation des fumes d'un appareil de chauffage à combustion de bois,fioul ou gaz. My present invention relates to a device for recovering the heat from a smoke evacuation pipe from a wood, oil or gas combustion heater.

Les différents récupérateurs de chaleur sont mis en place uniquement sur des appareils à combustion de bois. The various heat recuperators are installed only on wood combustion appliances.

La présente invention permet de recupérer la chaleur sur tous les tuyaux d'évacuation des gaz bruts quelque soit la nature du combustible. The present invention makes it possible to recover the heat on all the raw gas discharge pipes whatever the nature of the fuel.

Les récupérateurs de chaleur nctuels récuperent la chaleur sur les parois du foyer en fonte de l'appareil de chauffage donc leur installation nécessite le remplacement de l'appa reil existant par un appareil avec récupérateur de chaleur incorpore avec toute l'installation et le cout que cela implique. The current heat recuperators recover the heat on the walls of the cast iron hearth of the heating appliance, therefore their installation requires the replacement of the existing appliance by an appliance with heat recovery incorporated with all the installation and the cost that that implies.

La présente invention permet,par simple remplacement d'une partie du tuyau d'évacuation déa fumées,d'adapter immédiate- ment un récupérateur de chaleur sur toutes sortes de poule,
lie dispositif selon l'invention comporte un corps cylindrique principal adaptable aux deux extrémités,par emboite- ment,au tuyau d'évacuation des fumees de l'appareil existant
Tout le long de ce corps cylindrique sont empiles ou certies des ailettes perforées permettant de diffuser la chaleur du corps cylindrique du dispositif,chauffé par les gaz brules,à l'air ambiant circulant à travers ces ailettes perforées.The present invention makes it possible, by simply replacing part of the smoke evacuation pipe, to immediately adapt a heat recovery unit to all kinds of hens,
The device according to the invention comprises a main cylindrical body adaptable at the two ends, by interlocking, to the smoke evacuation pipe of the existing device
All along this cylindrical body are stacked or certified perforated fins making it possible to diffuse the heat of the cylindrical body of the device, heated by the burnt gases, to the ambient air circulating through these perforated fins.

L'ensemble corps cylindrique-ailettes étant lui même entouré par un carter ajusté oblige l'air ambiant,aspiré par un extracteur d'air externe au dispositif,de circuler à travers toutes les ailettes perforées. The whole cylindrical body-fins being itself surrounded by an adjusted casing forces the ambient air, sucked in by an air extractor external to the device, to circulate through all the perforated fins.

lie carter a sur sa partie haute une embouchure qui lui permet d'être raccordé à une gaine d'aspiration d'air chaud afin d'envoyer celui-ci dans une autre pièce de la maison. The housing has on its upper part a mouth which allows it to be connected to a hot air suction duct in order to send it to another room in the house.

La base du carter aspirant l'air ambiant est équipée d'un filtre 9 air afin de retenir les poussières. The base of the ambient air suction housing is fitted with an air filter 9 to retain dust.

L'ensemble du dispositif selon l'invention peut être entre autre réalisé par matriçage,poinçonnage ou ajustage de pièces m8talliues galvanisées ou émaillées,ou bien par moulage en différents alliages à des cotes permettant un montage serré de l'ensemble. The entire device according to the invention can be produced, among other things, by stamping, punching or adjusting galvanized or enamelled metal parts, or else by molding in different alloys at dimensions allowing tight assembly of the assembly.
