Description

BOITIER DE CLIMATISATION, NOTAMMENT POUR VEHICULE  AIR CONDITIONING UNIT, IN PARTICULAR FOR A VEHICLE
AUTOMOBILE  AUTOMOBILE
La présente invention a pour objet un boîtier de climatisation, notamment pour un véhicule automobile. The present invention relates to an air conditioning unit, in particular for a motor vehicle.
Il est connu des dispositifs de chauffage électrique destinés à être intégrés dans des boîtiers de climatisation de véhicule. Il s'agit soit de radiateurs additionnels, combinés avec des radiateurs de chauffage parcourus par un fluide caloporteur, dans les véhicules à moteur thermique, soit de radiateurs principaux, dans les véhicules électriques ou hybrides. Electric heating devices are known to be integrated in vehicle air conditioning units. These are either additional radiators, combined with heating radiators covered by a heat transfer fluid, in vehicles with a combustion engine or main radiators, in electric or hybrid vehicles.
De tels dispositifs de chauffage comprennent un cadre support accueillant des unité de chauffe munis d'éléments chauffants. Les unités de chauffe sont disposées parallèlement les unes aux autres et des électrodes alimentent indépendamment les éléments chauffants de chaque unité de chauffe depuis des bornes de connexion respectives reliées à un boîtier d'alimentation.  Such heating devices comprise a support frame accommodating heating units provided with heating elements. The heating units are arranged parallel to each other and electrodes independently supply the heating elements of each heating unit from respective connection terminals connected to a power supply unit.
Par ailleurs, il est connu des boîtiers de climatisation permettant de chauffer à des températures différentes un flux d'air destiné à être dirigé vers le conducteur et un flux d'air destiné à être envoyé vers le passager avant, voire des flux d'air destinés à être envoyé vers d'autres passager du véhicule.  Furthermore, it is known air conditioning housings for heating at different temperatures an air flow intended to be directed towards the driver and a flow of air to be sent to the front passenger, or even air flow intended to be sent to other passengers of the vehicle.
Les radiateurs de chauffage électrique proposée à ce jour en ce sens, tel quel dans le document WO 16/171478, sont particulièrement complexes et éloignés des configurations standards.  The electric heating radiators proposed to date in this sense, as such in WO 16/171478, are particularly complex and far from standard configurations.
L'invention a pour objectif de pallier au moins en partie les inconvénients mentionnés plus haut et propose à cette fin un boîtier de climatisation, notamment pour véhicule automobile, le boîtier comprenant un corps, configuré pour guider un premier flux d'air en direction d'une première zone, notamment une zone conducteur, et un deuxième flux d'air en direction d'une seconde zone, notamment une zone passager avant, et un dispositif de chauffage configuré pour chauffer le premier et/ou le deuxième flux d'air à partir d'un courant électrique, ledit dispositif de chauffage comprenant des éléments chauffant regroupés en unités de chauffe alimentées sélectivement en courant, au moins une desdites unités de chauffe étant positionnée de façon à chauffer uniquement le premier flux et au moins une autre desdites unités de chauffe étant positionnée de façon à chauffer uniquement le deuxième flux. En disposant de la sorte le dispositif de chauffage dans le boîtier de climatisation, c'est-à-dire, en disposant le dispositif de chauffage dans le boîtier de manière à ce que les unités de chauffe, ou au moins une partie d'entre elles, ne chauffent que l'un des deux flux d'air, on peut chauffer sélectivement la zone choisie tout en conservant des dispositifs de chauffage de configuration standard, notamment, des dispositifs de chauffage dans lesquels les éléments chauffant d'une même unité de chauffe sont tous alimentés en parallèle, qui plus est par seulement deux électrodes, l'ensemble des électrodes restant parallèles entre elles et reliées à un même boîtier d'alimentation. On évite ainsi d'avoir à multiplier le nombre et/ou la configuration des électrodes pour réussir à moduler le chauffage en fonction de la zone visée. The aim of the invention is to overcome at least part of the drawbacks mentioned above and proposes for this purpose an air-conditioning unit, in particular for a motor vehicle, the housing comprising a body, configured to guide a first air flow in the direction of a first zone, in particular a conducting zone, and a second air flow in the direction of a second zone, in particular a front passenger zone, and a heating device configured to heat the first and / or the second air flow from an electric current, said heating device comprising grouped heating elements in heating units selectively energized, at least one of said heating units being positioned to heat only the first stream and at least one of said other heating units being positioned to heat only the second stream. By thus arranging the heater in the air conditioning case, i.e., placing the heater in the housing so that the heating units, or at least a part of it they only heat one of the two air flows, the selected zone can be selectively heated while keeping standard configuration heating devices, in particular, heating devices in which the heating elements of the same unit of heating. heaters are all supplied in parallel, moreover by only two electrodes, the set of electrodes remaining parallel to each other and connected to the same power supply box. This avoids having to multiply the number and / or configuration of the electrodes to successfully modulate the heating according to the target area.

- la figure 5 est une vue de coupe illustrant de façon plus complète qu'à la figure 4 mais selon la même orientation un boîtier de climatisation conforme à l'invention. Comme illustré aux différentes figures, l'invention concerne un boîtier de climatisation 1 , notamment pour véhicule automobile. Le boîtier comprend un corps 2 qui n'est ici illustré qu'en partie.  - Figure 5 is a sectional view illustrating more fully than in Figure 4 but in the same orientation an air conditioning unit according to the invention. As illustrated in the various figures, the invention relates to an air conditioning unit 1, in particular for a motor vehicle. The housing comprises a body 2 which is only partially illustrated here.
Ledit corps 2 est configuré pour guider un premier flux d'air en direction d'une première zone, notamment une zone destinée à être occupée par un conducteur du véhicule, et un deuxième flux d'air en direction d'une seconde zone, notamment une zone destinée à être occupée par un passager avant du véhicule. En variante et toujours selon l'invention, le boîtier est configuré pour guider un ou plusieurs autres flux d'air respectivement en direction d'une ou plusieurs autres zones du véhicule, notamment une zone destinée à être occupée par des passagers arrière du véhicule. Pour cela le corps 2 comprend des parois 3 séparant l'intérieur du boîtier de l'extérieur ainsi que différentes cloisons dont l'une est illustrée ici schématiquement selon un trait mixte repéré 4 aux figures 1 et 3, la ou lesdites cloisons permettant de définir chacune des flux d'air au sein d'une même veine d'air définie par le corps du boîtier. Said body 2 is configured to guide a first air flow towards a first zone, in particular an area intended to be occupied by a driver of the vehicle, and a second air flow in direction of a second zone, in particular an area intended to be occupied by a front passenger of the vehicle. Alternatively and still according to the invention, the housing is configured to guide one or more other air flows respectively towards one or more other areas of the vehicle, including a zone to be occupied by rear passengers of the vehicle. For this, the body 2 comprises walls 3 separating the inside of the housing from the outside as well as various partitions, one of which is illustrated here schematically in a mixed line marked 4 in FIGS. 1 and 3, the one or more partitions defining each of the air flows within the same air stream defined by the body of the housing.
Ledit boîtier comprend en outre un dispositif de chauffage 6 configuré pour chauffer le premier et/ou le deuxième flux d'air à partir d'un courant électrique. Il s'agit, par exemple, d'un dispositif de chauffage, dit haute tension, c'est-à-dire destiné à être alimenté par un courant continu (DC) ou alternatif (AC) présentant une tension électrique supérieure à 60 V, notamment compris entre 60 et 1000 V, plus particulièrement compris entre 180 et 600 V, et/ou permettant de dégager une puissance de chauffe sur l'air ou une puissance électrique consommée supérieure à 2 KW, notamment comprise entre 2 kW et 10 kW. Said housing further comprises a heater 6 configured to heat the first and / or second airflow from an electric current. This is, for example, a heating device, said high voltage, that is to say intended to be supplied by a direct current (DC) or alternating (AC) having a voltage greater than 60 V , in particular between 60 and 1000 V, more particularly between 180 and 600 V, and / or making it possible to release a heating power on the air or a consumed electric power greater than 2 KW, in particular between 2 kW and 10 kW .
Ledit dispositif de chauffage comporte préférentiellement un module de chauffe 10, configuré pour chauffer le premier et le deuxième flux d'air. Ledit module de chauffe 10 présente ici une configuration sensiblement parallélépipédique, s'étendant en surface. Il est destiné à être positionné de façon transversale au flux d'air à réchauffer. Lesdits flux d'air sont perpendiculaire au plan des figures pour les figures 1 et 3. Dans l'exemple illustré, en amont du dispositif de chauffage 6, le corps 2 du boîtier est configuré pour guider un flux d'air commun, illustré F aux figures 2 et 4, la séparation du flux commun pour former le premier et le deuxième flux d'air à l'aide de la ou des cloisons évoquées plus haut intervenant, par exemple, juste en aval du dispositif de chauffage 6, selon le sens de circulation de l'air dans le boîtier. Said heating device preferably comprises a heating module 10, configured to heat the first and the second air flow. Said heating module 10 here has a substantially parallelepipedal configuration, extending on the surface. It is intended to be positioned transversely to the flow of air to be heated. Said air flows are perpendicular to the plane of the figures for FIGS. 1 and 3. In the example illustrated, upstream of the heating device 6, the body 2 of the housing is configured to guide a common air flow, illustrated in FIG. in FIGS. 2 and 4, the separation of the common flow to form the first and the second air flow using the above-mentioned partition (s) mentioned above, for example, just downstream of the heating device 6, according to the direction of air flow in the housing.
Ledit dispositif de chauffage 6 comprend des éléments chauffant, non-représentés. Les éléments chauffant sont, par exemple, des résistances à effet CTP (pour coefficient de température positif). Said heater 6 comprises heating elements, not shown. The heating elements are, for example, PTC resistors (for positive temperature coefficient).
Lesdits éléments chauffant sont regroupés en unités de chauffe 8 (illustrées seulement figure 1 ). Lesdites unités de chauffe 8 sont alimentées sélectivement en courant. On entend par là que chaque unité de chauffe 8 est alimentée en courant indépendamment des autres et peut donc être parcourue par un courant différent, notamment par son intensité, du courant parcourant les autres unités de chauffe 8. La valeur du courant en jeu ici est en particulier la valeur du courant moyen ou du courant efficace. Said heating elements are grouped into heating units 8 (illustrated only in FIG. 1). Said heating units 8 are selectively powered. This means that each heating unit 8 is supplied with current independently of the others and can therefore be traversed by a different current, in particular by its intensity, the current flowing through the other heating units 8. The value of the current involved here is in particular the value of the average current or the effective current.
Lesdites unités de chauffe 8 comprennent avantageusement des barrettes support 12 accueillant les éléments chauffant, ces derniers étant situés les uns à la suite des autres le long de chaque barrette. Lesdits éléments chauffant sont connectés électriquement en parallèle, notamment à l'aide d'électrodes, non-représentées, situées sur ladite barrette 12. Préférentiellement, lesdits éléments chauffant sont répartis régulièrement le long desdites barrettes 12. Said heating units 8 advantageously comprise support bars 12 accommodating the heating elements, the latter being located one after the other along each bar. Said heating elements are electrically connected in parallel, in particular using electrodes, not shown, located on said strip 12. Preferably, said heating elements are evenly distributed along said strips 12.
Ledit module de chauffe 10 contient lesdites unités de chauffe 8. Il est ici logé dans le corps 2 du boîtier de climatisation. Le module de chauffe 10 peut encore comprendre des dissipateurs thermiques, non- représentés, par exemple des ailettes, en relation de contact thermique avec les éléments chauffant. Les dissipateurs sont positionnés, notamment, entre lesdites barrettes 12. Ledit module de chauffe comprend une cadre 14, notamment en matière plastique, accueillant lesdites unités de chauffe 8. Ledit cadre comprend deux bords latéraux 17, 17' opposés ainsi qu'un bord proximal 18 et un bord distal 19 opposé, ledit bord proximal 18 et ledit bord distal 19 rejoignant les bords latéraux 17, 17' par exemple par leurs extrémités. Ledit cadre 14 est préférentiellement muni de renforts 16 s'étendant transversalement entre les deux bords latéraux 17, 17' du cadre 14. La ou les barrettes 12 s'étendent longitudinalement du bord proximal 18 au bord distal 19. Said heating module 10 contains said heating units 8. It is here housed in the body 2 of the air conditioning unit. The heating module 10 may further comprise heat sinks, not shown, for example fins, in thermal contact relation with the heating elements. The dissipators are positioned, in particular, between said bars 12. Said heating module comprises a frame 14, in particular a plastic frame, accommodating said heating units 8. Said frame comprises two opposite lateral edges 17, 17 'as well as a proximal edge 18 and an opposite distal edge 19, said proximal edge 18 and said distal edge 19 joining the side edges 17, 17 'for example by their ends. Said frame 14 is preferably provided with reinforcements 16 extending transversely between the two lateral edges 17, 17 'of the frame 14. The bar or bars 12 extend longitudinally from the proximal edge 18 to the distal edge 19.
Préférentiellement, le dispositif de chauffage 6 comprend en outre une unité 20 de distribution et/ou de commande du courant circulant dans ledit module de chauffe 10. Ladite unité de chauffage et/ou de commande est avantageusement configurée pour piloter le courant alimentant le module de chauffe 10, en particulier les différentes unités de chauffe 8, par exemple à l'aide de commutateurs pilotés, permettant de contrôler respectivement une circulation de courant dans chacune des unités de chauffe 8. Il s'agit, notamment, de transistors, par exemple du type Mosfet ou IGBT, fonctionnant en particulier par modulation de largeur d'impulsions. Preferably, the heating device 6 further comprises a unit 20 for distributing and / or controlling the current flowing in said heating module 10. Said heating and / or control unit is advantageously configured to control the current supplying the module. 10, in particular the different heating units 8, for example using controlled switches, for controlling respectively a flow of current in each of the heating units 8. These include, for example, transistors, for example of the Mosfet or IGBT type, operating in particular by pulse width modulation.
Ladite unité 20 de distribution et/ou de commande comprend un boîtier 22 situé le long du bord proximal 18 du cadre 14. Ledit boîtier 22 comprend une face de connexion 24, reliée audit cadre 12, servant au montage et/ou à la fixation du module de chauffe 10. Ladite unité de distribution et/ou de commande 20 comprend en outre un connecteur 28 à un circuit d'alimentation en courant et/ou à un réseau de transmission de données, notamment un circuit et/ou un réseau du véhicule. Ledit connecteur 28 est ici situé sur une face du boîtier 22 opposé à la face de connexion 24. Comme illustré aux figures 1 et 2, ledit dispositif de chauffage 6 comprend outre, ici une, ou des plaques 26 de dissipation thermique permettant d'évacuer la chaleur produite par ladite unité 20 de distribution et/ou de commande de courant. La plaque de dissipation thermique 26 s'étend le long et à partir de la face de connexion 24 en direction du bord distal 19 du cadre 14. Ladite plaque de dissipation thermique 26 est située au niveau de l'une des faces du cadre 14, de préférence en amont selon le sens de circulation du flux d'air. Elle masque la base des barrettes 12 tout en laissant passer le ou les flux d'air à ce niveau, ceci avec des pertes de charge sur l'air favorisant les échanges thermiques. Said dispensing and / or control unit 20 comprises a housing 22 located along the proximal edge 18 of the frame 14. Said housing 22 comprises a connecting face 24, connected to said frame 12, serving for mounting and / or fixing the heating module 10. Said distribution and / or control unit 20 further comprises a connector 28 to a current supply circuit and / or to a data transmission network, in particular a circuit and / or a network of the vehicle. . Said connector 28 is here located on a face of the housing 22 opposite the connection face 24. As illustrated in FIGS. 1 and 2, said heating device 6 furthermore comprises, here, one or more heat dissipation plates 26 making it possible to evacuate the heat produced by said distribution and / or current control unit 20. The heat dissipation plate 26 extends along and from the connection face 24 towards the distal edge 19 of the frame 14. Said heat dissipation plate 26 is located at one of the faces of the frame 14, preferably upstream in the direction of flow of the air flow. It hides the base of the bars 12 while allowing the air flow or flows to this level, this with pressure losses on the air favoring heat exchange.
Ladite unité 20 de distribution et/ou de commande du courant est ici située à l'extérieur du corps 2 du boîtier de climatisation 1 . Ledit corps 2 du boîtier de climatisation 1 comprend un orifice 27 d'introduction du module de chauffe, notamment réalisé dans l'une des parois 3 dudit corps 2. Said distribution and / or current control unit 20 is here located outside the body 2 of the air conditioning unit 1. Said body 2 of the air conditioning unit 1 comprises an orifice 27 for introducing the heating module, in particular made in one of the walls 3 of said body 2.
Dans l'exemple illustré, le dispositif de chauffage 6 et plus particulièrement le module de chauffe 10 comprennent une première partie A et une deuxième partie B. La première partie A est destinée à être traversée par le premier flux d'air et la deuxième partie B est destinée à être traversée par le deuxième flux d'air. Les première et deuxième parties A et B sont virtuellement séparées par ledit trait mixte 4. Le dispositif de chauffage comprend ici trois unités de chauffe 8 dans chacune desdites première et deuxième parties A et B. In the example illustrated, the heating device 6 and more particularly the heating module 10 comprise a first part A and a second part B. The first part A is intended to be traversed by the first air flow and the second part B is intended to be traversed by the second air flow. The first and second parts A and B are virtually separated by said mixed line 4. The heating device here comprises three heating units 8 in each of said first and second parts A and B.
Plus généralement, selon l'invention, au moins une desdites unités de chauffe 8 est positionnée de façon à chauffer uniquement le premier flux et au moins une autre desdites unités de chauffe 8 est positionnée de façon à chauffer uniquement le deuxième flux. Préférentiellement, chacune desdites unités de chauffe 8 est positionnée de façon à chauffer uniquement l'un des premier ou deuxième flux. Autrement dit, chacune desdites unités de chauffe 8 est située soit dans la première partie A, soit dans la seconde B mais pas à cheval sur l'une et l'autre desdites parties A et B. Grâce à une telle orientation du dispositif de chauffage 6 et plus particulièrement grâce à une telle disposition des unités de chauffe 8 dans le corps 2 du boîtier de climatisation, il est possible de réaliser un chauffage sélectif des zones de l'habitacle parcourues par les flux d'air traversant le dispositif de chauffage 6. En effet, en modulant le courant circulant dans chacune de unités de chauffe 8 ou à tout le moins en modulant le courant circulant dans les unités de chauffe destinées à réchauffer le même flux, c'est-à-dire en modulant le courant circulant dans les unités chauffe appartenant à une même partie A ou B, on peut réchauffer chacun des flux d'air aux températures souhaitées. Tout en offrant à chacun des passagers du véhicule la température qu'il désire, il est ainsi possible de limiter la consommation de courant et augmenter en conséquence l'autonomie du véhicule électrique ou hybride équipé. More generally, according to the invention, at least one of said heating units 8 is positioned to heat only the first stream and at least one of said other heating units 8 is positioned to heat only the second stream. Preferably, each of said heating units 8 is positioned to heat only one of the first or second flows. In other words, each said heating units 8 is situated either in the first part A or in the second B but not straddling the one and the other of said parts A and B. Thanks to such an orientation of the heating device 6 and more particularly thanks to such an arrangement of the heating units 8 in the body 2 of the air conditioning unit, it is possible to selectively heat the areas of the passenger compartment through which the air flows through the heating device 6. In fact, by modulating the current flowing in each of the heating units 8 or at least by modulating the current flowing in the heating units intended to heat the same flow, that is to say by modulating the current flowing in the heating units belonging to the same part A or B, it is possible to heat each of the air flows to the desired temperatures. While offering each passenger of the vehicle the desired temperature, it is possible to limit the power consumption and increase accordingly the autonomy of the electric vehicle or hybrid equipped.
Dans une telle configuration, ledit orifice d'introduction 27 du module de chauffe 10 est avantageusement situé en partie basse dudit corps 2. Ainsi, ladite unité 20 de distribution et/ou de commande du courant est située sous le corps 2 du boîtier de climatisation, en position d'utilisation du boîtier et comme cela est le cas sur les figures. Autrement dit, le dispositif de chauffage 6 est introduit dans le corps 2 du boîtier par le fond plutôt que par le côté comme c'est le cas avec les boîtiers de l'état de l'art. In such a configuration, said introduction orifice 27 of the heating module 10 is advantageously located at the bottom of said body 2. Thus, said distribution and / or current control unit 20 is located under the body 2 of the air conditioning unit in the position of use of the housing and as is the case in the figures. In other words, the heater 6 is introduced into the body 2 of the housing by the bottom rather than the side as is the case with the housings of the state of the art.
Comme illustré aux figures 3 et 4, selon un aspect spécifique de l'invention, le module de chauffe 10 comprend une fenêtre 30, qui forme ici une zone C, configurée pour permettre un passage d'air offrant une perte de charge sur l'air, réduite ou nulle par rapport au reste du module de chauffe 10. Ladite fenêtre 30 est située, par exemple, au voisinage de ladite unité 20 de distribution et/ou de commande, particulièrement entre ladite unité 20 de distribution et l'un desdits renforts 16, encore plus particulièrement entre la face de connexion 24 et le renfort 16 le plus proche. As illustrated in FIGS. 3 and 4, according to a specific aspect of the invention, the heating module 10 comprises a window 30, which here forms a zone C, configured to allow an air passage providing a pressure drop on the air, reduced or zero compared to the rest of the heating module 10. Said window 30 is located, for example, in the vicinity of said distribution and / or control unit 20, particularly between said distribution unit 20 and one of said reinforcements 16, even more particularly between the connection face 24 and the reinforcement 16 the nearest.
Ainsi, selon l'exemple illustré, les plaques de dissipation thermique 26 peuvent être interrompues au droit de ladite fenêtre 30. En variante, la dissipation thermique de la chaleur produite par l'unité 20 de distribution et/ou de commande est réalisée par tout autre moyen connu de l'homme de l'art. Thus, according to the illustrated example, the heat dissipation plates 26 can be interrupted at the right of said window 30. In a variant, the heat dissipation of the heat produced by the distribution and / or control unit 20 is achieved by any another means known to those skilled in the art.
Les dissipateurs prévus entre les barrettes 12 dans le mode de réalisation des figures 1 et 2 pourront aussi s'interrompre au droit de ladite fenêtre 30 plutôt que de s'étendre jusqu'à proximité de la face de connexion 24. La configuration de la base des barrettes 12 pourra également être adaptée afin de ne pas se trouver au droit de ladite fenêtre 30, notamment en longeant les bords de ladite fenêtre 30. The dissipators provided between the bars 12 in the embodiment of Figures 1 and 2 may also be interrupted to the right of said window 30 rather than extending to near the connection face 24. The configuration of the base strips 12 may also be adapted so as not to be in line with said window 30, in particular along the edges of said window 30.
La configuration du dispositif de chauffage des figures 3 et 4 est plus spécialement avantageuse quand elle est combinée à une localisation de ladite fenêtre 30 en partie basse du boîtier, telle qu'évoquée plus haut, en particulier dans le cas de boîtier de climatisation permettant de diriger de l'air en direction de passagers arrière du véhicule. The configuration of the heating device of FIGS. 3 and 4 is especially advantageous when it is combined with a location of said window 30 at the bottom of the housing, as mentioned above, in particular in the case of an air conditioning unit allowing direct air towards the rear passengers of the vehicle.
Dans un tel cas de figure, comme cela ressort mieux de la figure 5, ledit boîtier est configuré pour la circulation d'un flux d'air F1 , dit avant, et d'un flux d'air F2, dit arrière, par exemple à l'aide de cloisons supplémentaires, non illustrées. Le flux d'air avant F1 est destiné à réchauffer la partie de l'habitacle accueillant le conducteur et le passager avant. Autrement dit, il est composé du premier et du second flux d'air provenant respectivement des zones A et B du module de chauffe 10. Le flux arrière est composé du flux provenant de la zone C du module de chauffe. In such a case, as best shown in Figure 5, said housing is configured for the circulation of a flow of air F1, said before, and a flow of air F2, said back, for example using additional partitions, not shown. The front airflow F1 is intended to warm the part of the cabin welcoming the driver and the passenger before. In other words, it is composed of the first and second air flows respectively from zones A and B of the heating module 10. The back flow is composed of the flow from the zone C of the heating module.
Le boîtier est alors configuré pour que le flux d'air arrière passe à travers ladite fenêtre 30 et pour que le flux d'air avant passe à travers le reste du module de chauffe. Dans un tel mode de fonctionnement, comme déjà dit, le premier flux d'air guidé vers une première zone de l'habitacle et le deuxième flux d'air guidé vers une deuxième zone de l'habitacle sont préférentiellement issus du flux d'air avant. Quant au deuxième flux d'air arrière, il peut traverser le dispositif de chauffage 6 sans être réchauffé et sans subir de pertes de charges ou alors très peu. Cela étant, en cas de besoin, le flux d'air arrière pourra aussi être réchauffé par un dispositif de chauffage indépendant, notamment placé en aval, selon le sens de circulation du flux d'air, dans le boîtier. The housing is then configured for the rear air flow to pass through said window 30 and for the front air flow to pass through the remainder of the heating module. In such a mode of operation, as already said, the first air flow guided to a first zone of the passenger compartment and the second air flow guided to a second zone of the passenger compartment are preferably derived from the air flow. before. As for the second rear air flow, it can pass through the heating device 6 without being heated and without undergoing losses or very little. However, if necessary, the rear air flow can also be heated by an independent heater, in particular placed downstream, in the direction of flow of the air flow in the housing.
A la figure 5, on constate que ledit boîtier 1 comprend au moins une entrée d'air 50 et plusieurs sorties d'air, notamment une première sortie 52 en direction du parebrise du véhicule, une deuxième sortie 54 en direction du conducteur et des passagers avant, une troisième sortie 56 en direction des pieds des occupants de l'habitacle du véhicule et/ou une quatrième sortie 57 en direction de la zone arrière. Le boîtier est configuré pour que flux d'air avant F1 soit envoyé sélectivement vers la ou les sorties 52, 54, 56, en particulier en fonction de la position de différents volets de distribution 58-60. Ledit boîtier est en outre configuré pour diriger le flux d'air arrière F2 vers la quatrième sortie 57, située en partie basse du boîtier. Ledit boîtier comprend en outre une zone de mixage 62 de tout ou partie du flux d'air avant F1 et du flux d'air arrière F2. Ladite zone de mixage 62 est située, par exemple, entre ladite fenêtre 30 et ladite quatrième sortie 57. In FIG. 5, it can be seen that said housing 1 comprises at least one air inlet 50 and several air outlets, in particular a first outlet 52 towards the windshield of the vehicle, a second outlet 54 towards the driver and the passengers before, a third exit 56 towards the feet of the occupants of the passenger compartment of the vehicle and / or a fourth exit 57 towards the rear area. The housing is configured so that front air flow F1 is selectively sent to the outlet (s) 52, 54, 56, in particular depending on the position of different distribution flaps 58-60. Said housing is further configured to direct the rear airflow F2 to the fourth outlet 57, located at the bottom of the housing. Said housing further comprises a mixing zone 62 of all or part of the front air flow F1 and the air flow rear F2. Said mixing zone 62 is situated, for example, between said window 30 and said fourth outlet 57.
Ledit boîtier peut comprendre en outre un ou plusieurs volets, non représentés, pour diriger l'air vers la fenêtre 30 ou le reste du corps de chauffe 10, le ou lesdits volets étant préférentiellement situés en amont du dispositif de chauffage selon le sens de l'écoulement de l'air. Said housing may further comprise one or more shutters, not shown, for directing the air towards the window 30 or the rest of the heating body 10, the said flap or flaps being preferably located upstream of the heating device in the direction of the flow of air.
Ledit boîtier comprend encore un évaporateur 70, situé dans le corps 2 du boîtier. Ledit évaporateur 70 est positionné en amont du dispositif de chauffage selon le sens d'écoulement de l'air, en particulier en amont des zones A et B du module de chauffe. Said housing further comprises an evaporator 70, located in the body 2 of the housing. Said evaporator 70 is positioned upstream of the heating device in the direction of flow of the air, in particular upstream of zones A and B of the heating module.
Pour revenir au dispositif de chauffage, comme déjà indiqué, chacune des parties A et B comprend trois unités de chauffe 8. Il est à noter que, plus généralement, ledit dispositif de chauffage 6 comprend un même nombre d'unités de chauffe 8 positionnées de façon à chauffer le premier flux et le deuxième flux. Autrement dit, chacune des zones A et B comprend le même nombre d'unités de chauffe 8. De plus les unités de chauffe 8 sont identiques entre elles. Une telle configuration favorise la standardisation du module de chauffe 10 et facilite la configuration de l'unité 20 de distribution et/ou de commande. To return to the heating device, as already indicated, each of the parts A and B comprises three heating units 8. It should be noted that, more generally, said heating device 6 comprises the same number of heating units 8 positioned from to heat the first stream and the second stream. In other words, each of the zones A and B comprises the same number of heating units 8. In addition, the heating units 8 are identical to each other. Such a configuration favors the standardization of the heating module 10 and facilitates the configuration of the distribution and / or control unit 20.
