Abstract

The invention relates to a device enabling electric current to be produced from a heat source, in particular solar radiation, through the creation and use of a thermostatic bimetallic strip whose most expandable face is a compound of carbon fibres with high elasticity. The device consists of a solar reflector 1 heating a thermostatic bimetallic strip 3 whose sudden deflection entrains a piece of ferromagnetic metal 9 whose movement gives rise to an electric current in the coils 10 which is collected via an end-use apparatus 11. The device according to the invention is particularly intended for saving energy in all areas of industry and for reducing the cost of electricity generating systems.

utilisation d'un déflecteur conuenseur du rayonnement solaire sur un @@@ame
thermique .Device for the direct transformation of solar energy into electricity by

thermal.

L'énergie solaire est rarement utilisé dans le grand public pour produire directement de l'électricité, et quand cela est le coût est prohibitif.Solar energy is rarely used by the general public to generate electricity directly, and when this is the cost is prohibitive.

En ltétat actuel de la technique dans ce domaine les procédés connus font
appels à deux grandes catégories , l'une se basant sur les phenoménes de
thermo-couples à rondement infime servant essentiellement à la régulation d'
engins , liautre se basant sur les effets photo électriques dits voltaïques d'un bon rendement mais d'un coût trés élevé au watt fourni : Le prisent dis- positif à pour but d'étre d'un rendement moyen et de construction économique,
il se décompose en trois parties: -Le ou les condenseurs d'énergie solaire ou réflecteur.In the current state of the art in this field, the known methods make
calls to two main categories, one based on the phenomena of
thermo-couples with very small roundness mainly used for the regulation of
gear, the other based on the so-called voltaic photoelectric effects of good performance but of a very high cost per watt supplied: The device is designed to be of average efficiency and economical construction,
it breaks down into three parts: -The solar energy condenser or reflector.

Description of the three constituent sets.

Le réflecteur condenseur . figures 1 et 2 I1 est constitué par une surface mince (1) et réfléchissante d'allure verticale bombée de haut en bas et de droite à gauche. C'est approximativement la coupe verticale d'un paraboloïde, coupe paralléle à l'axe du paraboloi1de à une certaine distance de cet axe . I1 est fixé sur un socle (25 suffisament
lourd pour résister aux effets du vent .Le miroir ainsi constitué est orienté
sa concavité vers le sud ou la course du soleil .The condenser reflector. Figures 1 and 2 I1 is constituted by a thin surface (1) and reflective vertical appearance curved from top to bottom and from right to left. It is approximately the vertical section of a paraboloid, section parallel to the axis of the paraboloid at a certain distance from this axis. I1 is fixed on a base (25 sufficient
heavy to withstand the effects of wind. The mirror thus formed is oriented
its concavity towards the south or the course of the sun.

Les rayons du soleil convergent en un foyer dont la position varie avec la
course du soleil ,mais ce dispositif permet le dit déplacement du foyer sans
que ce dernier ne quitte la cible bilame (3) compte tenue de la surface imp
ortante et de la forme du bilame qui enveloppe le lieu géométrique du foyer mobile . Le bilame est fixé sur une ou plusieurs consoles (4).The rays of the sun converge in a focus whose position varies with the
course of the sun, but this device allows the said displacement of the hearth without
the latter leaves the bimetal target (3) taking into account the imp
ortante and the shape of the bimetallic strip which envelops the geometrical place of the mobile hearth. The bimetallic strip is fixed on one or more consoles (4).

Le bilame thermique de conversion chaleur en travail mécanique .figures 1 et 2
Le bilame est constitué par deux ou plusieurs couches de matgriaux à corffi-
cient de dilatation thermiques différents ,le plus dilatable (5à sa face
libre tourné vers la face concave du miroir et reçoit le rayonnement solaire
condensé le moins dilatable (6) constitue l'autre face. Le bilame est munie
d'une tige (7) vers son centre . Lorsqu'il est chauffé par la chaleur solair, condensée par le miroir il subit un déplacement,au bout d'un certain temps,qui
tire sur son centre (7) vers le miroir et provoqsle un retournement brutal du bilame.The thermal bimetal for converting heat into mechanical work. Figures 1 and 2
The bimetal strip is made up of two or more layers of material with corffi
different thermal expansion cient, the most expandable (5 on its face
free turned towards the concave face of the mirror and receives solar radiation
the least expandable condensate (6) constitutes the other face. The bimetallic strip is provided
a rod (7) towards its center. When it is heated by solar heat, condensed by the mirror, it undergoes a displacement, after a certain time, which
pulls on its center (7) towards the mirror and provokes a sudden reversal of the bimetallic strip.

The electromagnetic circuit for converting the mechanical work of the bimetallic strip into electrical energy. figure; 1.2.

Le circuit électrique est constitué par un circuit fermé de forme appropriée en métal ferromagnétique à haute perméabilité )(8). The electrical circuit consists of a closed circuit of suitable shape made of ferromagnetic metal with high permeability) (8).

Ce circuit cependant posséde une partie amovible (95 solidaire de la tige(75 du bilame
Le circuit ferromagnétique est entouré par un ou plusieurs bobinages électri- ques (10). This circuit however has a removable part (95 integral with the rod (75 of the bimetallic strip
The ferromagnetic circuit is surrounded by one or more electrical windings (10).

L'aimantation est obtenue par une alimentation -en courant continu d'une des bobines ,elle peut également étre obtenue par l'adjonction d'aimants permanents magnétisants le noyaux ferromagnetique$ (8!.ou également ce dernier peut étre à aimantation permanente
Principe de fonctionnement de ltensemble entier. figure t.2. The magnetization is obtained by a DC power supply from one of the coils, it can also be obtained by the addition of permanent magnets magnetizing the ferromagnetic cores $ (8!. Or also the latter can be with permanent magnetization
Principle of operation of the whole assembly. figure t.2.

temps d'échauf!ement: figure 1.  warm-up time: Figure 1.

L'électro-aimant est alimenté, le bilame Subit à Urle température donnée we déflexion qui ouvre le circuit ferromagnétique (8) la déflexion du bilame coupe le circuit aimanté ,elle engendre ainsi un courant d'utilisation qui est pris par un appareils d'utilisation ou par le relais d'un accumulateur électrique (11).The electromagnet is supplied, the bimetallic strip is subjected to the url given temperature we deflection which opens the ferromagnetic circuit (8) the deflection of the bimetallic strip cuts off the magnetic circuit, it thus generates a current of use which is taken by an apparatus of use or by the relay of an electric accumulator (11).

La déflexion du bilame consomme une anergie mécanique pour la déflexions et également pour l'accumulateur (11).Deflection of the bimetallic strip consumes mechanical anergy for deflection and also for the accumulator (11).

Temps de refroidissemnts . figure 2.Cooling times. figure 2.

Le bilan énergétique montre qu'il y a refroidissement du bilame (3) au à la déflexion décrite ci-dessus et à la consommation électrique Le réglage du bilame est fait de façon à ce que sa course et son refroidissement soient tels qu'il subit alors une déflexion en sens inverse ,dûe à son refroidissementet à l'attraction du circuit aimanté. The energy balance shows that there is cooling of the bimetallic strip (3) at the deflection described above and at the electrical consumption. The adjustment of the bimetallic strip is done so that its stroke and its cooling are such that it undergoes then a deflection in the opposite direction, due to its cooling and to the attraction of the magnetic circuit.

Le dispositif est alors remis en phase d'échauffement et ainsi de suite
Si le circuit d'utilisation est ouvert ,c'est à dire n'est pas en marche,il y a moins d'énergie cédée par le bilame lors de sa déflexion il ne se refroidi donc pas assez pour étre rappellé en phase avant échauffement
Le bilame n'étant pas assez froid ne reviendra pas pour réamorcer le dispositif lors de l'utilisation (11) il faut que la mise en marche de ce dernier comporte une augmentation de l'alimentation de l'électro-aimant juste pendant la premiére phase de démarrage
Si le soleil vient à baisser ou à disparaitre ,la déflexion du bilame ne peut plus se produire par manque d'rchauffement, le dispositif se coupe de lui-meme. The device is then returned to the heating phase and so on.
If the operating circuit is open, i.e. is not in operation, there is less energy given up by the bimetallic strip during its deflection so it does not cool down enough to be called back in phase before heating up
The bimetallic strip not being cold enough will not return to re-prime the device during use (11) it is necessary that the starting of the latter involves an increase in the supply of the electromagnet just during the first Beginning phase
If the sun goes down or disappears, the deflection of the bimetallic strip can no longer occur due to lack of heating, the device cuts itself off.
