Description

L'invention concerne un dispositif de chauffage électrique destiné à être traversé par un flux d'air à réchauffer. L'invention s'applique plus particulièrement aux appareils de chauffage et/ou climatisation pour véhicules automobiles. Le document EP 2 056 036 montre l'état de la technique le plus proche de la revendication 1.The invention relates to an electric heating device intended to be traversed by a flow of air to be heated. The invention applies more particularly to heating and / or air conditioning apparatus for motor vehicles. The document EP 2,056,036 shows the state of the art closest to claim 1.

De façon habituelle, le réchauffage de l'air destiné au chauffage de l'habitacle d'un véhicule automobile, ainsi qu'au désembuage et au dégivrage est assuré par passage d'un flux d'air à travers un échangeur de chaleur, plus précisément par un échange de chaleur entre le flux d'air et un liquide, en général le liquide de refroidissement du moteur.In the usual way, the heating of the air for heating the passenger compartment of a motor vehicle, as well as demisting and defrosting is ensured by passing an air flow through a heat exchanger, plus precisely by a heat exchange between the air flow and a liquid, usually the engine coolant.

Cependant, ce mode de chauffage peut s'avérer inadapté ou insuffisant pour garantir un chauffage rapide et efficace de l'habitacle, notamment dans certaines situations telles que :

  • un préconditionnement avant démarrage du moteur pour assurer un réchauffement de l'habitacle, ainsi qu'un dégivrage ou désembuage, de façon télécommandée ou préprogrammée, avant utilisation du véhicule en environnement très froid,
  • une montée très rapide souhaitée de la température dans l'habitacle,
  • une incapacité de l'échangeur de chaleur à fournir les calories nécessaires à un réchauffage satisfaisant de l'air pour assurer les fonctions de chauffage ainsi que de dégivrage et désembuage éventuels, comme cela se produit pendant un certain temps après démarrage, avec certains types de moteurs à faible déperdition thermique.
However, this heating mode may be inadequate or insufficient to ensure a rapid and efficient heating of the passenger compartment, especially in certain situations such as:
  • preconditioning before starting the engine to ensure a warming of the passenger compartment, as well as defrosting or demisting, remotely or pre-programmed, before use of the vehicle in a very cold environment,
  • a very fast rise in the temperature inside the passenger compartment,
  • an inability of the heat exchanger to provide the necessary calories for a satisfactory reheat of the air to provide the heating functions as well as any defrosting and demisting, as happens for a while after start up, with certain types of engines with low heat loss.

Pour pallier ces inconvénients, une solution connue consiste à adjoindre à l'échangeur de chaleur un dispositif de chauffage électrique, autrement appelé radiateur électrique, disposé en aval de l'échangeur dans le conduit de circulation d'air à réchauffer.To overcome these drawbacks, a known solution consists in adding to the heat exchanger an electric heating device, otherwise known as an electric heater, disposed downstream of the exchanger in the air circulation duct to be heated.

Ce dispositif de chauffage électrique comporte des modules chauffants électriques disposés dans des logements d'un cadre du dispositif de chauffage de manière à être exposés directement à l'air traversant le dispositif de chauffage électrique pour réaliser un appoint de chaleur quasiment immédiat.This electric heating device comprises electric heating modules arranged in housings of a frame of the heating device so as to be exposed directly to the air passing through the electric heating device to achieve a quasi-immediate heat build-up.

Cependant, on a constaté que le cadre recevant les modules chauffants peut présenter une structure trop flexible pouvant altérer ou détériorer les modules chauffants.However, it has been found that the frame receiving the heating modules can have a structure that is too flexible to alter or damage the heating modules.

De plus, lors de l'assemblage des modules chauffants dans le cadre, on peut rencontrer des difficultés d'insertion des modules chauffants dans les logements associés du cadre.In addition, when assembling the heating modules in the frame, it may be difficult to insert the heating modules in the associated housing of the frame.

L'invention a donc pour objectif un dispositif de chauffage électrique permettant de pallier ces inconvénients de l'art antérieur.The invention therefore aims at an electric heating device to overcome these disadvantages of the prior art.

À cet effet, l'invention a pour objet un dispositif de chauffage électrique pour réchauffer un flux d'air comportant un cadre de forme générale sensiblement parallélépipédique avec une face d'entrée d'air et une face opposée de sortie d'air, le cadre recevant un nombre prédéterminé de modules chauffants électriques dans des logements associés du cadre destinés à être traversés par le flux d'air à réchauffer, caractérisé en ce que le cadre comporte sur les faces d'entrée et de sortie d'air du cadre une pluralité de nervures de renfort structurel et de guidage desdits modules chauffants dans les logements associés du cadre, lesdites nervures étant orientées selon une direction oblique par rapport à la direction d'insertion desdits modules chauffants dans lesdits logements.For this purpose, the subject of the invention is an electric heating device for heating an air flow comprising a frame of generally parallelepipedal shape with an air inlet face and an opposite air outlet face, the frame receiving a predetermined number of electric heating modules in associated housing of the frame to be traversed by the flow of air to be heated, characterized in that the frame has on the air inlet and outlet faces of the frame a plurality of structural reinforcing ribs and guiding said heating modules in the associated housing frame, said ribs being oriented in a direction oblique to the direction of insertion of said heating modules in said housing.

La direction oblique des nervures permet d'éviter que les modules chauffants butent contre les nervures pendant la phases d'insertion/translation desdits modules, contrairement à des nervures perpendiculaires par rapport à la direction d'insertion des modules chauffants, ce qui facilite l'assemblage du dispositif de chauffage.The oblique direction of the ribs prevents the heating modules abut against the ribs during the insertion / translation phases of said modules, unlike ribs perpendicular to the direction of insertion of the heating modules, which facilitates the assembly of the heater.

En outre, ces nervures obliques permettent également un renfort structurel du cadre en améliorant le comportement en torsion du cadre.In addition, these oblique ribs also allow a structural reinforcement of the frame by improving the torsional behavior of the frame.

Ledit dispositif de chauffage peut en outre comporter une ou plusieurs caractéristiques suivantes, prises séparément ou en combinaison :

  • lesdites nervures présentent respectivement une forme générale sensiblement en « X »,
  • deux nervures de renfort et de guidage consécutives sont respectivement disposées sur la face d'entrée d'air et sur la face de sortie d'air du cadre,
  • la distance entre deux nervures de renfort et de guidage consécutives est choisie de manière à assurer un guidage continu desdits modules chauffants,
  • lesdites nervures sont agencées de façon sensiblement symétriques par rapport à un axe de symétrie du cadre,
  • lesdites nervures forment un angle compris entre 2 et 88° avec ladite direction d'insertion.
Said heater may further comprise one or more of the following features, taken separately or in combination:
  • said ribs respectively have a general shape substantially in "X",
  • two consecutive reinforcing and guiding ribs are respectively disposed on the air intake face and on the air outlet face of the frame,
  • the distance between two consecutive reinforcing and guiding ribs is chosen from in order to ensure continuous guidance of said heating modules,
  • said ribs are arranged substantially symmetrically with respect to an axis of symmetry of the frame,
  • said ribs form an angle of between 2 and 88 ° with said direction of insertion.

L'invention concerne également un appareil de chauffage et/ou climatisation pour véhicule automobile, caractérisé en ce qu'il comporte un dispositif de chauffage électrique tel que défini précédemment.The invention also relates to a heating and / or air conditioning device for a motor vehicle, characterized in that it comprises an electric heating device as defined above.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante, donnée à titre d'exemple illustratif et non limitatif, et des dessins annexés parmi lesquels :

  • la figure 1 est une vue partielle schématique d'un appareil de chauffage pour véhicule automobile,

  • la figure 4 illustre un exemple de cadre pour maintenir les modules chauffants du dispositif de chauffage de la figure 2, et
  • la figure 5 est une vue en perspective partielle du cadre de la figure 4.
Other features and advantages of the invention will emerge more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings among which:
  • the figure 1 is a schematic partial view of a heating apparatus for a motor vehicle,
  • the figure 2 illustrates an electric heater device of the figure 1 ,
  • the figure 3 represents an embodiment of a heating module of the heating device of the figure 2 ,
  • the figure 4 illustrates an example of a frame to hold the heating modules of the heater of the figure 2 , and
  • the figure 5 is a partial perspective view of the frame of the figure 4 .

Dans ces figures, les éléments sensiblement identiques portent les mêmes références.In these figures, the substantially identical elements bear the same references.

La figure 1 montre une partie d'un appareil de chauffage et/ou climatisation 1 de véhicule automobile, comprenant un boîtier 3 délimitant un canal 5 pour le passage du flux d'air à réchauffer. Le canal 5 amène l'air vers des bouches de chauffage et de désembuage/dégivrage 7,9 pour être distribué sélectivement dans l'habitacle selon les positions de volets de mixage et de distribution 11. Le débit d'air dans le canal 5 est produit par un ventilateur 13, ou pulseur, recevant de l'air extérieur ou de l'air de circulation en provenance de l'habitacle. Le réchauffage de l'air, lorsqu'il est nécessaire, est assuré par un échangeur de chaleur à liquide éventuel 15, utilisant le liquide de refroidissement du moteur comme liquide caloporteur et par un dispositif de chauffage électrique 17, autrement appelé radiateur électrique. L'échangeur 15 et le radiateur électrique 17 sont disposés dans le canal 5, le premier étant situé en amont du second. En l'absence d'échangeur 15, le chauffage de l'air est assuré par le seul dispositif de chauffage électrique 17.The figure 1 shows a part of a heater and / or air conditioning 1 of a motor vehicle, comprising a housing 3 defining a channel 5 for the passage of the flow of air to be heated. The channel 5 brings the air to the heating and defogging / defrosting ports 7,9 to be selectively distributed in the passenger compartment according to the mixing and distribution flaps positions 11. The air flow in the channel 5 is produced by a fan 13, or blower, receiving outside air or circulating air from the passenger compartment. The reheating of the air, when necessary, is provided by an optional liquid heat exchanger 15, using the engine coolant as heat transfer liquid and by a heating device electrical 17, otherwise called electric heater. The exchanger 15 and the electric heater 17 are arranged in the channel 5, the first being located upstream of the second. In the absence of exchanger 15, the heating of the air is provided by the single electric heating device 17.

En référence à la figure 2, un tel dispositif de chauffage électrique 17 traversé par le flux d'air à réchauffer comprend un bloc de chauffage 19 comprenant un cadre 21 de forme générale sensiblement parallélépipédique avec deux faces opposées d'entrée et de sortie d'air, un boîtier de commande 23 du bloc de chauffage 19, autrement appelé « driver », fixé sur un côté du cadre 21, et par exemple un talon 25 formé d'une seule pièce avec le cadre 21 par moulage sur le côté du cadre 21 opposé au côté portant le boîtier de commande 23.With reference to the figure 2 such an electric heating device 17 traversed by the flow of air to be heated comprises a heating block 19 comprising a frame 21 of generally parallelepipedal shape with two opposite faces of inlet and air outlet, a control box 23 of the heating block 19, otherwise called "driver", fixed on one side of the frame 21, and for example a heel 25 formed integrally with the frame 21 by molding on the side of the frame 21 opposite the side bearing the control box 23.

Un tel dispositif de chauffage électrique 17 pouvant atteindre en fonctionnement des températures élevées, par exemple de l'ordre de 150°C, le cadre 21 est réalisé en un matériau, par exemple plastique, capable de supporter ces températures élevées atteintes en fonctionnement.Such an electric heater 17 can reach high temperatures in operation, for example of the order of 150 ° C, the frame 21 is made of a material, for example plastic, capable of withstanding these high temperatures reached in operation.

Ce dispositif de chauffage électrique 17 peut être dans un appareil 1 mono-zone, c'est à dire qu'il permet de réchauffer l'ensemble de l'habitacle, ou encore multi-zones pour réchauffer plusieurs zones distinctes de l'habitacle, afin de séparer par exemple le côté conducteur du côté passager ou encore le désembuage et le chauffage des pieds.This electric heating device 17 can be in a single-zone apparatus 1, that is to say it can heat the entire cabin, or multi-zone to warm several different areas of the cabin, to separate for example the driver side of the passenger side or the demisting and heating feet.

Pour cela, on peut prévoir dans l'appareil 1, une séparation agencée par exemple sensiblement au milieu du cadre 21 en s'étendant parallèlement à un côté longitudinal du cadre 21 au niveau de l'axe A1 et éventuellement une autre séparation agencée par exemple sensiblement au milieu du cadre 21 en s'étendant parallèlement à un côté latéral du cadre 21 au niveau de l'axe A2, pour diviser le cadre 21 par exemple en quatre portions distinctes avant gauche, avant droit, arrière gauche et arrière droit, réchauffant respectivement une zone distincte associée de l'habitacle.For this, provision can be made in the apparatus 1, a separation arranged for example substantially in the middle of the frame 21 extending parallel to a longitudinal side of the frame 21 at the axis A1 and optionally another separation arranged for example substantially in the middle of the frame 21 extending parallel to a lateral side of the frame 21 at the axis A2, to divide the frame 21 for example into four distinct portions front left, right front, left rear and right rear, warming respectively a separate zone associated with the passenger compartment.

Le réchauffage du flux d'air est assuré par des modules chauffants 27 agencés dans des logements 29 du cadre 21 de façon à être traversés par le flux d'air à réchauffer, ces logements 29 étant délimités dans l'exemple illustré, par des parois longitudinales du cadre 21 et peuvent être intercalés entre des zones ajourées 30 du cadre 21 pour réguler le débit d'air.Heating of the air flow is ensured by heating modules 27 arranged in housings 29 of the frame 21 so as to be traversed by the flow of air to be heated, these housings 29 being delimited in the example illustrated by walls longitudinally of the frame 21 and may be interposed between perforated zones 30 of the frame 21 to regulate the air flow.

Le nombre de modules chauffants 27 est déterminé en fonction de la puissance calorifique totale requise suivant l'application. Ces modules chauffants 27 sont disposés parallèlement les uns aux autres et s'étendent sur toute la longueur du cadre 21 du bloc de chauffage 19, de manière à être exposés directement au flux d'air traversant le bloc de chauffage 19.The number of heating modules 27 is determined as a function of the total heat output required according to the application. These heating modules 27 are arranged parallel to each other and extend over the entire length of the frame 21 of the heating block 19, so as to be exposed directly to the air flow passing through the heating block 19.

Un module chauffant 27 peut comporter des éléments résistifs de type à coefficient de température positif (CTP). Ces éléments sont protégés contre des échauffements excessifs ou contre une surintensité.A heating module 27 may comprise resistive elements of positive temperature coefficient (PTC) type. These elements are protected against overheating or overcurrent.

Selon une variante de réalisation illustrée sur la figure 3, un module chauffant 27 comporte deux électrodes 31 qui s'étendent longitudinalement, chacune enserrant un dissipateur thermique 33 formé par exemple d'un ruban métallique plissé ou ondulé et venant en appui contre les éléments résistifs ou pierres CTP 35. Pour plus de clarté, le dissipateur thermique 33 n'est pas représenté dans son intégralité sur la figure 3. Bien entendu, le dissipateur thermique 33 s'étend sur toute la longueur dans l'électrode 31.According to an embodiment variant illustrated on the figure 3 , a heating module 27 comprises two electrodes 31 which extend longitudinally, each enclosing a heat sink 33 formed for example of a pleated or corrugated metal strip and bearing against the resistive elements or CTP stones 35. For the sake of clarity, the heatsink 33 is not represented in its entirety on the figure 3 . Of course, the heat sink 33 extends over the entire length in the electrode 31.

Selon une autre variante de réalisation du module chauffant 27 (non représentée), les électrodes prennent en sandwich les éléments résistifs alors que les dissipateurs thermiques formés par le ruban métallique sont placés contre les faces extérieures libres desdites électrodes. En d'autres termes, le module chauffant 27 comporte deux dissipateurs thermiques qui enserrent deux électrodes entre lesquelles sont placées des pierres CTP ou éléments résistifs.According to another alternative embodiment of the heating module 27 (not shown), the electrodes sandwich the resistive elements while the heat sinks formed by the metal ribbon are placed against the free outer faces of said electrodes. In other words, the heating module 27 comprises two heat sinks which enclose two electrodes between which are placed CTP stones or resistive elements.

Les deux électrodes 31 d'un module chauffant 27 sont parcourues par l'intermédiaire de deux terminaux 37 par des potentiels électriques différents, par exemple un premier potentiel disponible dans le véhicule, tel que la tension de batterie, et un second potentiel, tel que la masse.The two electrodes 31 of a heating module 27 are traversed via two terminals 37 by different electrical potentials, for example a first potential available in the vehicle, such as the battery voltage, and a second potential, such as the mass.

Dans l'exemple illustré sur la figure 2, lorsque trois modules chauffants 27 sont prévus, on a alors une rangée de six terminaux 37 à alimenter en énergie électrique.In the example shown on the figure 2 when three heating modules 27 are provided, there is then a row of six terminals 37 to supply electrical energy.

En se référant aux figures 2, 4 et 5, on constate que le cadre 21 comporte des moyens de guidage et éventuellement des moyens de maintien des modules chauffants 27 dans les logements 29 du cadre 21.Referring to figures 2 , 4 and 5 , it is found that the frame 21 comprises guide means and possibly means for holding the heating modules 27 in the housing 29 of the frame 21.

Concernant les moyens de guidage, le cadre 21 comporte sur ses faces d'entrée A et de sortie B d'air une pluralité de nervures de guidage 39 par exemple de forme générale en « X », orientées selon une direction oblique par rapport à la direction d'insertion D des modules chauffants dans les logements 29 du cadre 21 représentée par la flèche, en formant par exemple un angle compris entre 2 et 88°.Regarding the guiding means, the frame 21 comprises on its inlet faces A and air outlet B a plurality of guide ribs 39, for example of generally "X" shape, oriented in a direction oblique to the direction of insertion D of the heating modules in the housing 29 of the frame 21 shown by the arrow, for example forming an angle of between 2 and 88 °.

Avec une telle orientation, le guidage des modules chauffants 27 lors de leur insertion dans le cadre 21 est facilité.With such an orientation, the guidance of the heating modules 27 during their insertion in the frame 21 is facilitated.

De plus, ces nervures de guidage 39 assurent également un renfort structurel du cadre 21 limitant la flexibilité du cadre 21 améliorant ainsi le comportement mécanique en torsion du cadre 21. On peut prévoir des nervures supplémentaires 41 perpendiculaires à la direction d'insertion D au niveau des logements 29 et/ou des zones ajourées 30 pour un renfort local du cadre 21.In addition, these guide ribs 39 also provide a structural reinforcement of the frame 21 limiting the flexibility of the frame 21 thus improving the mechanical torsional behavior of the frame 21. Additional ribs 41 may be provided perpendicular to the insertion direction D at the level of the frame 21. housing 29 and / or perforated zones 30 for a local reinforcement of the frame 21.

Les nervures 39 peuvent être disposées à la fois de part et d'autre des logements 29 du cadre 21 pour recevoir les modules chauffants 27 et de part et d'autre des zones ajourées 30 du cadre 21. Lorsqu'un module chauffant 27 est inséré dans un logement 29 du cadre 21, le point de contact entre le module chauffant 27 se déplace le long de la nervure 39 au niveau du logement 29.The ribs 39 can be disposed both on either side of the housings 29 of the frame 21 to receive the heating modules 27 and on either side of the perforated zones 30 of the frame 21. When a heating module 27 is inserted in a housing 29 of the frame 21, the point of contact between the heating module 27 moves along the rib 39 at the housing 29.

Les nervures 39 peuvent également être disposées alternativement sur la face d'entrée d'air A et sur la face de sortie d'air B du cadre 21. Plus précisément, lorsqu'une première nervure 39 est disposée sur la face d'entrée d'air A, la nervure consécutive est disposée sur la face de sortie d'air B. Dans ce cas, les nervures 39 sur les deux faces A,B opposées ne sont pas en vis-à-vis mais sont décalées de manière à équilibrer les pertes de charges.The ribs 39 may also be arranged alternately on the air intake face A and on the air outlet face B of the frame 21. More specifically, when a first rib 39 is disposed on the inlet face of air A, the consecutive rib is disposed on the air outlet face B. In this case, the ribs 39 on the two faces A, B opposite are not vis-à-vis but are offset so as to balance the losses of charges.

On notera que le cadre 21 et les nervures 39 forment une seule pièce unitaire formé par moulage d'une matière plastique.It will be noted that the frame 21 and the ribs 39 form a single unitary piece formed by molding a plastic material.

Ainsi, lorsqu'un module chauffant 27 est inséré dans un logement 29 associé du cadre 21, par la gauche sur les figures 2 et 4 selon la direction d'insertion D, le module chauffant 27 est guidé en continu le long du logement 29 successivement par les nervures 39.Thus, when a heating module 27 is inserted in an associated housing 29 of the frame 21, by the left on the figures 2 and 4 according to the insertion direction D, the heating module 27 is guided continuously along the housing 29 successively by the ribs 39.

À cet effet, entre deux nervures 39 consécutives, plus précisément entre le dernier point de contact P 1 d'une première nervure 39 avec le module chauffant 27 inséré, et le premier point de contact P 2 de la deuxième nervure 39 consécutive, la distance d est calculée pour garantir le guidage continu du module chauffant 27 durant son insertion.For this purpose, between two consecutive ribs 39, more precisely between the last point of contact P 1 of a first rib 39 with the heating module 27 inserted, and the first contact point P 2 of the second rib 39 consecutive, the distance d is calculated to ensure the continuous guidance of the heating module 27 during its insertion.

De plus, les nervures 39 peuvent être agencées de façon sensiblement symétriques par rapport à un ou aux deux axes A1 et A2 de symétrie du cadre 21 de manière à équilibrer les pertes de charges haut/bas et/ou gauche/droite.In addition, the ribs 39 may be arranged substantially symmetrically with respect to one or both axes A1 and A2 of symmetry of the frame 21 so as to balance the high / low and / or left / right pressure losses.

On notera tout particulièrement que les points de croisement de trois nervures 39 en « X » consécutives ne sont pas alignés sur un même axe, ces points de croisement sont donc décalés les uns par rapport aux autres dans la direction perpendiculaire à au sens d'introduction D des modules chauffants 27, c'est-à-dire dans la direction A2.It will be noted in particular that the crossing points of three consecutive "X" ribs 39 are not aligned on the same axis, these crossing points are therefore offset relative to each other in the direction perpendicular to the direction of introduction. D heating modules 27, that is to say in the direction A2.

On notera aussi que un ou plusieurs points de croisement de nervures 39 en « X » sont placés sur la bord qui délimite le logement 29, c'est-à-dire au droit de la paroi qui est à la frontière entre le logement et la zone ajourée 30 contiguë. On limite ainsi l'impact négatif sur la perte de charge qu'un tel croisement peut créer en le superposant avec un autre élément de structure du cadre.Note also that one or more crossing points of ribs 39 at "X" are placed on the edge which delimits the housing 29, that is to say at the right of the wall which is at the boundary between the housing and the open area 30 contiguous. This limits the negative impact on the pressure drop that such crossover can create by superimposing it with another element of frame structure.

De la même manière, un ou plusieurs points de croisement de nervures 39 en « X » sont placés au droit des pierres CTP ou éléments résistifs d'un module chauffant 27.In the same way, one or more crossing points of ribs 39 in "X" are placed in line with the CTP stones or resistive elements of a heating module 27.

Le cadre 21 peut présenter encore d'autres moyens supplémentaires de guidage des modules chauffants 27 tels qu'une ou plusieurs saillies 43 sur les parois des logements 29 s'étendant vers l'intérieur des logements 29.The frame 21 may also have other additional means for guiding the heating modules 27 such as one or more projections 43 on the walls of the housings 29 extending towards the inside of the housings 29.

En ce qui concerne les moyens de maintien des modules chauffants 27 dans le cadre 21, le cadre 21 peut présenter des crochets flexibles 45, par exemple de forme générale sensiblement en « S » servant de butées flexibles contre les extrémités des modules chauffants 27.With regard to the means for holding the heating modules 27 in the frame 21, the frame 21 may have flexible hooks 45, for example of generally "S" -shaped general shape serving as flexible stops against the ends of the heating modules 27.

Le cadre 21 peut encore présenter des languettes flexibles 47 pour exercer une force de frottement sur le module chauffant 27. À cet effet, les languettes 47 forment un angle non nul par rapport à la direction d'insertion D des modules chauffants 27 dans les logements 29.The frame 21 may also have flexible tabs 47 to exert a frictional force on the heating module 27. To this end, the tabs 47 form a non-zero angle to the direction of insertion D of the heating modules 27 in the housing 29.

Par ailleurs, le cadre 21 peut être fixé par exemple par clipsage au boîtier 23 et peut comporter à cet effet, des fourreaux de clipsage 51 dans lesquels s'insèrent des organes de clipsage 53 complémentaires portés par le boîtier 23.Furthermore, the frame 21 can be fixed for example by clipping to the housing 23 and may comprise for this purpose, clipping sleeves 51 in which are inserted complementary clipping members 53 carried by the housing 23.

Ce boîtier de commande 23 est quant à lui réalisé dans un matériau capable de supporter les températures élevées atteintes en fonctionnement du dispositif de chauffage 17 et peut être formé d'un corps de boîtier 23a et d'un couvercle 23b fixés entre eux par exemple par clipsage par le biais de moyens de clipsage 54.This control box 23 is in turn made of a material capable of withstanding the high temperatures achieved during operation of the heating device 17 and may be formed of a housing body 23a and a cover 23b fixed to each other for example by clipping by means of clipping means 54.

De plus, le boîtier 23 comporte un circuit d'alimentation électrique monté sur un support tel qu'une carte à circuit imprimé et relié à une source d'alimentation électrique par l'intermédiaire de deux conducteurs métalliques 55 et 55', également appelés « bus barres », dont un premier 55 peut être mis au premier potentiel, et le second 55' au second potentiel. À titre d'exemple, le circuit d'alimentation électrique comporte des transistors électroniques (non représentés) pour autoriser ou non le passage du courant dans les modules chauffants 27.In addition, the housing 23 comprises a power supply circuit mounted on a support such as a printed circuit board and connected to a power supply source via two metal conductors 55 and 55 ', also called " bus bars ", a first 55 can be put to the first potential, and the second 55 'to the second potential. For example, the power supply circuit comprises electronic transistors (not shown) to allow or not the passage of current in the heating modules 27.

En outre, des terminaux 57 reliés aux conducteurs 55,55' conduisent le courant électrique vers les terminaux 37 des modules chauffants 27 quand le transistor concerné autorise le passage du courant. Dans l'exemple illustré dans lequel le dispositif de chauffage électrique 17 comporte trois modules chauffants 27, six terminaux 57 sont prévus pour alimenter en énergie les six terminaux correspondants 37 des modules chauffants 27. À cet effet, les terminaux 37 et 57 sont connectés par exemple par soudage ou encore par clinchage obtenant alors un point de clinchage 59 lors de la connexion.In addition, terminals 57 connected to the conductors 55,55 'conduct the electric current to the terminals 37 of the heating modules 27 when the transistor concerned allows the passage of current. In the example illustrated in which the electric heating device 17 comprises three heating modules 27, six terminals 57 are provided for supplying power to the six corresponding terminals 37 of the heating modules 27. For this purpose, the terminals 37 and 57 are connected by example by welding or by clinching then obtaining a clinching point 59 during the connection.

De plus, le circuit d'alimentation électrique peut recevoir des informations sur la puissance à délivrer à travers un connecteur 61.In addition, the power supply circuit can receive information on the power to be delivered through a connector 61.

Par ailleurs, pour compenser le déséquilibre de pertes de charges dues aux ouvertures nécessaires pour la connexion des terminaux 37 et 57 traversées par le flux d'air à réchauffer, le talon 25 opposé au boîtier 23 peut être un talon d'équilibrage de pertes de charge présentant des ouvertures 63 destinées à être traversées par le flux d'air à réchauffer.Furthermore, to compensate for the imbalance of pressure losses due to the openings necessary for the connection of the terminals 37 and 57 traversed by the flow of air to be heated, the heel 25 opposite the housing 23 may be a heel of balance of losses of charge having openings 63 to be traversed by the flow of air to be heated.

On comprend donc que la structure du cadre 21 avec les nervures 39 servant à la fois pour le guidage des modules chauffants 27 lors de l'insertion dans le cadre 21 et pour le renfort structurel du cadre, permet de faciliter l'assemblage du dispositif de chauffage 17 et d'éviter la détérioration des modules chauffants 27 qui serait due à une trop grande flexibilité du cadre 21 maintenant les modules chauffants 27.It is therefore understood that the structure of the frame 21 with the ribs 39 serving the for guiding the heating modules 27 during insertion into the frame 21 and for the structural reinforcement of the frame, makes it easier to assemble the heating device 17 and to prevent the deterioration of the heating modules 27 which would be due to too much flexibility of the frame 21 now the heating modules 27.
