L'appareil illustré sur les dessins com
porte une coque -enveloppe formée par deux demi-coques 1
et 2 assemblées. L'assemblage peut etre effectué par clip
sage , grâce à des reliefs périphériques , respectivement
3 et 4 ( figure 4) . Cette coque 1 , 2 est en matière mou
lée , et elle comporte
- à une extrémité , un raccord d'arrivée 5 , pour un li
quide , tel que de l'eau , du gazole , etc.. ;
- à l'autre extrémité , un raccord de sortie 6 .Entre
les deux extrémités , elle comporte un certain nombre de
cloisons intérieures transversales 7 , dans lesquelles
sont découpées , alternativement en haut , puis en bas ,
des encoches de passage 8 . L'empilage des cloisons 7
est traversé dans toute sa longueur , par un alésage
longitudinal 9 , dans lequel vient se loger le tube enve
loppe 13 , d'un ensemble chauffant . Une fois le disposi
tif assemblé ( figures 1 , 3 , 5 , 7 ) , on voit que les
cloisons 7 et les encoches alternées 8 , forment des chi
canes , grâce auxquelles la circula-.on du liquide admis
suivant la direction de la flèche 10 par le raccord 5 (fi
gures 5 et 7) se développe selon le trajet sinueux défini
par les flèches 11 , avant de parvenir à l'autre extrémi
té , où ltécbulement sort par le raccord 6 , comme indi diqué par la flèche 12
Le tube-enveloppe 13 est préférablement un tube en métal filé ,dont la section transversale comporte un méplat intérieur longitudinal 14.The apparatus illustrated in the drawings com
carries a shell -envelope formed by two half-shells 1
and 2 assemblies. Assembly can be done by clip
wise, thanks to peripheral reliefs, respectively
3 and 4 (Figure 4). This shell 1, 2 is made of soft material
and it has
- at one end, an inlet connector 5, for a li
what, such as water, diesel, etc .;
- at the other end, an outlet fitting 6.
both ends it has a number of
transverse interior partitions 7, in which
are cut, alternately at the top, then at the bottom,
passage slots 8. Stacking partitions 7
is traversed in its entire length by a bore
longitudinal 9, in which the inverted tube is housed
lope 13, of a heating assembly. Once the disposi
tif assembled (Figures 1, 3, 5, 7), we see that the
partitions 7 and alternating notches 8, form chi
canes, thanks to which the circulation of the admitted liquid
in the direction of arrow 10 through connection 5 (fi
gures 5 and 7) develops along the defined winding path
by arrows 11, before reaching the other extremi
tee, where the fog comes out through fitting 6, as indicated by arrow 12
The envelope tube 13 is preferably a spun metal tube, the cross section of which has a longitudinal internal flat 14.
Sur ce méplat 14 , on pose une plaquette 15 , en matière isolante , dans laquelle sont découpés des alvéoles 16
Chacun de ces alvéoles reçoit une pastille de céramique 17 d'un profil correspondant . L'épaisseur 18 de la plaquette 15 est préférablement légèrement inférieure à lté- paisseur 19 de chaque pastille 17 , ceci pour assurer un bon contact électrique , comme on le verra plus loin.On this flat 14, a plate 15 is placed, made of insulating material, from which are cut cells 16
Each of these cells receives a ceramic pellet 17 of a corresponding profile. The thickness 18 of the wafer 15 is preferably slightly less than the thickness 19 of each pad 17, this to ensure good electrical contact, as will be seen below.
Les alvéoles 16 et les pastilles 17 peuvent être , par exemple , de contour rectangulaire. The cells 16 and the pellets 17 can be, for example, of rectangular outline.
Chaque pastille de céramique 17 constitue une thermo-résistance à fonctionnement autorégulateur . Autrement dit , la résistivité de chaque pastille 17 augmente lorsque sa température augmente également . Cela permet d'utiliser les pastilles 17 comme des éléments chauffants auto-régulateurs , sans qu'il soit besoin d'y adjoindre un thermostat. Each ceramic chip 17 constitutes a heat resistance with self-regulating operation. In other words, the resistivity of each pellet 17 increases when its temperature also increases. This allows the pellets 17 to be used as self-regulating heating elements, without the need to add a thermostat.
Au-dessus des pastilles 17 , on place une barrette métallique 20 , par exemple à profil en U
Enfin , serré entre la barrette 20 , et la partie intérieure du tube 13 opposée au méplat 14 , on glisse légèrement à force un noyau de serrage 21 , réalisé en matière isolante . Préférablement ,il s'agit d'une pièce allongée plate en matière plastique , le long de laquelle sont prévus des découpages transversaux 22 ,et des bossages de poussée 23 .A son extrémité libre , le noyau de serrage 21 comporte préférablement un double crochet d'ancrage 24 , susceptible de venir s'encliqueter à force entre les griffes 25 prévues à cet effet sur la partie intérieure d'un bouchon d'extrémité 26
A son extrémité opposée , le noyau de serrage 21 se termine par un culot 27 en matière isolante , pourvue , à l'avant , alun siège d'étanchéité 28 , susceptible de venir s'ajuster sur la partie correspondante du tube-enveloppe 13 . Latéralement , dépasse de ce culot 27 , un bornier 29 , susceptible de traverser de façon étanche , grâce à un point 30 , une cheminée latérale 31 ( figures 4 et 5) , équipant la coque 1 , 2
Du bornier 29 , dépassent deux cosses d'alimentation 32 et 33 .Noyées dans la matière isolante du bornier 29 et du culot 27 , ces cosses 32 et 33 se prolongent respectivement par
- une languette haute 34 , orientée suivant la direction axiale du tube-enveloppe 13 , pour venir s'appliquer élastiquement contre sa paroi intérieure
- une languette basse 35 , orientée suivant la même direction , pour venir s'appliquer élastiquement contre la barrette métallique 20 après assemblage.Above the pellets 17, a metal bar 20, for example with a U-shaped profile, is placed
Finally, clamped between the bar 20 and the inner part of the tube 13 opposite the flat 14, a clamping core 21 is made to slide slightly by force, made of insulating material. Preferably, it is an elongated flat plastic part, along which transverse cutouts 22 are provided, and thrust bosses 23. At its free end, the clamping core 21 preferably comprises a double hook d anchor 24, capable of being snapped into place between the claws 25 provided for this purpose on the inner part of an end plug 26
At its opposite end, the clamping core 21 ends in a base 27 made of insulating material, provided, at the front, with a sealing seat 28, capable of fitting onto the corresponding part of the tube-shell 13. Laterally, protrudes from this base 27, a terminal block 29, capable of passing tightly, through a point 30, a lateral chimney 31 (Figures 4 and 5), fitted to the shell 1, 2
Terminal block 29, protrude two supply terminals 32 and 33. Embedded in the insulating material of terminal block 29 and base 27, these terminals 32 and 33 are extended respectively by
- A high tongue 34, oriented in the axial direction of the tube-envelope 13, to come to apply elastically against its inner wall
- A low tongue 35, oriented in the same direction, to be applied elastically against the metal bar 20 after assembly.
Le fonctionnement est le suivant:
L'assemblage des pièces illustrées
sur la figure 2 s'effectue de façon très simple , comme montré sur les figures 8 et 9 . En effet , il suffit d'enfiler légèrement à force dans le tube-enveloppe 13 , l'empilage des pièces montrées sur la figure 2 , pour que le noyau 21 soit soumis , par l'action de ses bossages 23 r un serrage transversal . Ce serrage maintient fermement le contact électrique de part et d'autre des pastilles 17 serrées entre le méplat métallique 14 et la barrette métallique 20 . En fin de course d'introduction , les languettes 34 et 35 assurent le raccordement élactrique ,d' une part du tube-enveloppe 13 , d'autre part , de la bar rette intérieure 20 . L'étanchéité de l'assemblage est assuré par clipsage du bouchon 26 sur les crochets d'extrémité 24 du noyau 21
L'ensemble chauffant 13 , 26 , 27 forme alors un bloc étanche ( figures 1 et 5) , autour duquel on resserre de façon étanche la coque-enveloppe 1 Ainsi , on voit que le liquide circulant dans la coque-enveloppe 1 , 2 , n'est en contact qu'avec un seul des deux pâles de la connexion électrique , à savoir uniquement avec le tube-enveloppe 13.The operation is as follows:
The assembly of the illustrated parts
in FIG. 2 is carried out in a very simple manner, as shown in FIGS. 8 and 9. Indeed, it suffices to thread slightly by force into the tube-envelope 13, the stacking of the parts shown in FIG. 2, so that the core 21 is subjected, by the action of its bosses 23 r, to a transverse tightening. This tightening firmly maintains the electrical contact on either side of the pads 17 clamped between the metal flat 14 and the metal bar 20. At the end of the introductory stroke, the tongues 34 and 35 ensure the electrical connection, on the one hand of the casing tube 13, and on the other hand, of the inner bar bar 20. The tightness of the assembly is ensured by clipping the plug 26 onto the end hooks 24 of the core 21
The heating assembly 13, 26, 27 then forms a sealed block (FIGS. 1 and 5), around which the shell-envelope 1 is tightly tightened. Thus, it can be seen that the liquid circulating in the shell-envelope 1, 2, is in contact with only one of the two blades of the electrical connection, namely only with the tube-envelope 13.
On est donc sûr qu'aucun risque n'apparait
- ni de court-circuit ( cas par exemple d'un courant alternatif en 220 volts)
- ni d'un phénomène d'électrolyse ( par exemple si les cosses 32 , 33 sont reliées à un courant continu de 12 volts ou de 24 volts)
En particulier, le liquide ne parvient jamais à l'intérieur du tube-enveloppe 13 We are therefore sure that no risk appears
- no short-circuit (case for example of an alternating current in 220 volts)
- neither of an electrolysis phenomenon (for example if the terminals 32, 33 are connected to a direct current of 12 volts or 24 volts)
In particular, the liquid never reaches the interior of the tube-envelope 13
