À titre d’exemple, les moyens de traitement thermique peuvent comprendre un évaporateur qui est destiné à refroidir et déshumidifier le flux d’air le traversant, ainsi qu’un radiateur, éventuellement associé à un radiateur additionnel, qui est destiné à réchauffer le flux d’air qui le traverse. [0003] In known manner, the housing houses a blower to circulate the air flow from the air inlet to the air outlet. The housing also houses one or more heat treatment means, such as heat exchangers, to heat and/or cool the air flow prior to its distribution inside the passenger compartment. For example, the heat treatment means may include an evaporator which is intended to cool and dehumidify the air flow passing through it, as well as a radiator, possibly associated with an additional radiator, which is intended to heat the flow. of air passing through it.
[0004] Il est connu, dans ces dispositifs, que le flux d’air entrant à l’intérieur du boîtier et éventuellement traité thermiquement soit admis dans une chambre, dite chambre de mixage, avant d’être distribué vers une ou plusieurs zones ou régions spécifiques de l’habitacle du véhicule, par exemple les zones avant et arrière, et/ou gauche et droite dans l’habitacle. À cet effet, la chambre est communication fluidique avec un ou plusieurs conduits de distribution d’air débouchant dans une région respective de l’habitacle. De tels conduits de distribution sont généralement pourvu d’au moins un organe de répartition, tel qu’un volet de répartition, afin de définir la proportion du flux d’air destiné à être distribué dans la région correspondante de l’habitacle.
[0005] Bien qu’un tel dispositif de chauffage, ventilation et/ou climatisation permette de réaliser une gestion aéraulique pour plusieurs zones ou régions de l’habitacle du véhicule, il existe toutefois de nombreuses contraintes en termes de volume et de poids pour ces dispositifs. [0004] It is known, in these devices, that the flow of air entering the interior of the housing and possibly heat-treated is admitted into a chamber, called a mixing chamber, before being distributed to one or more zones or specific regions of the vehicle cabin, for example the front and rear areas, and/or left and right in the cabin. For this purpose, the chamber is in fluid communication with one or more air distribution ducts opening into a respective region of the passenger compartment. Such distribution ducts are generally provided with at least one distribution member, such as a distribution flap, in order to define the proportion of the air flow intended to be distributed in the corresponding region of the passenger compartment. [0005] Although such a heating, ventilation and/or air conditioning device makes it possible to achieve airflow management for several zones or regions of the vehicle passenger compartment, there are however numerous constraints in terms of volume and weight for these devices.
[0006] En effet, les dispositifs de chauffage, ventilation et/ou climatisation sont généralement disposés sous la planche de bord du véhicule automobile, ceci implique le rehaussement des planches de bord limitant ainsi la visibilité du conducteur. Plus précisément, le boîtier est installé dans l’habitacle, entre une planche du bord du véhicule et une paroi, couramment appelée tablier ou pare feu, séparant l’habitacle du compartiment moteur du véhicule. [0006] Indeed, the heating, ventilation and/or air conditioning devices are generally arranged under the dashboard of the motor vehicle, this involves raising the dashboards thus limiting the driver's visibility. More precisely, the box is installed in the passenger compartment, between a dashboard board of the vehicle and a wall, commonly called an apron or firewall, separating the passenger compartment from the engine compartment of the vehicle.
[0007] Or, pour le confort des occupants du véhicule, il est souhaitable que l’espace intérieur de l’habitacle soit le plus vaste possible. En d’autres termes, pour maintenir un niveau de confort acceptable, il est souhaitable de réduire l’encombrement de certains composants, par exemple la planche de bord. Une telle réduction dimensionnelle rend alors compliqué le positionnement d’un dispositif de chauffage, ventilation et/ou climatisation tel que connu de l’art antérieur. [0007] However, for the comfort of the occupants of the vehicle, it is desirable that the interior space of the passenger compartment be as large as possible. In other words, to maintain an acceptable level of comfort, it is desirable to reduce the size of certain components, for example the dashboard. Such a dimensional reduction then makes the positioning of a heating, ventilation and/or air conditioning device as known from the prior art complicated.
[0008] Selon une autre solution, le boîtier est monté en plusieurs parties et en plusieurs étapes au sein du véhicule et ces différentes parties du boîtier sont solidarisées entre elles une fois montées dans le véhicule, par exemple par l’intermédiaire du tablier. Toutefois une telle solution complexifie le procédé de montage du boîtier et l’installation du dispositif de chauffage, ventilation et/ou climatisation au sein du véhicule. [0008] According to another solution, the housing is mounted in several parts and in several stages within the vehicle and these different parts of the housing are secured together once mounted in the vehicle, for example via the apron. However, such a solution complicates the assembly process of the housing and the installation of the heating, ventilation and/or air conditioning device within the vehicle.
[0009] Par ailleurs, une problématique constante dans le domaine automobile est l’insonorisation ou l’isolation acoustique au niveau du tablier de façon à atténuer la transmission de bruits en provenance du compartiment moteur vers l’habitacle. [0009] Furthermore, a constant problem in the automotive field is soundproofing or acoustic insulation at the level of the apron so as to attenuate the transmission of noise coming from the engine compartment to the passenger compartment.
[0010] La présente invention vise à pallier un ou plusieurs inconvénients de l’art antérieur en optimisant l’encombrement d’un dispositif de chauffage, ventilation et/ou climatisation et son installation dans un véhicule, tout en limitant les fuites acoustiques. [0010] The present invention aims to overcome one or more drawbacks of the prior art by optimizing the size of a heating, ventilation and/or air conditioning device and its installation in a vehicle, while limiting acoustic leaks.
[0011] À cet effet, l’invention a pour objet un dispositif de chauffage, ventilation et/ou climatisation, pour véhicule notamment automobile, le véhicule comportant un compartiment moteur et un habitacle, séparés par un tablier comprenant une ouverture. [0011] To this end, the subject of the invention is a heating, ventilation and/or air conditioning device, for a vehicle, in particular an automobile, the vehicle comprising an engine compartment and a passenger compartment, separated by an apron comprising an opening.
[0012] Ledit dispositif comprend un boîtier définissant :
une première partie présentant au moins une entrée d’air configurée pour l’admission d’un flux d’air dans le boîtier, et en communication fluidique avec une chambre destinée à être traversée par le flux d’air, et une deuxième partie présentant au moins un conduit de distribution d’air, en aval de la chambre selon l’écoulement du flux d’air, le conduit de distribution se terminant par une sortie d’air configurée pour déboucher dans au moins une zone de l’habitacle du véhicule. Said device comprises a housing defining: a first part having at least one air inlet configured for the admission of an air flow into the housing, and in fluid communication with a chamber intended to be crossed by the air flow, and a second part having at least one air distribution duct, downstream of the chamber according to the flow of the air flow, the distribution duct ending in an air outlet configured to open into at least one zone of the passenger compartment of the vehicle.
[0013] Selon l’invention, la première partie et la deuxième partie sont configurées pour être agencées de part et d’autre du tablier à l’état monté du boîtier dans le véhicule. [0013] According to the invention, the first part and the second part are configured to be arranged on either side of the apron in the mounted state of the housing in the vehicle.
[0014] Le boîtier est configuré pour être monté d’un seul tenant dans le véhicule et uniquement depuis un premier côté du tablier. La deuxième partie du boîtier est configurée pour traverser l’ouverture dans le tablier de manière à faire saillie d’un deuxième côté du tablier opposé au premier côté. [0014] The housing is configured to be mounted in one piece in the vehicle and only from a first side of the apron. The second portion of the housing is configured to pass through the opening in the apron so as to project from a second side of the apron opposite the first side.
[0015] De plus, le boîtier est configuré pour être monté d’un seul tenant dans le véhicule et uniquement depuis un premier côté du tablier. La deuxième partie du boîtier est configurée pour traverser l’ouverture dans le tablier de manière à faire saillie d’un deuxième côté du tablier opposé au premier côté. [0015] Furthermore, the housing is configured to be mounted in one piece in the vehicle and only from a first side of the apron. The second portion of the housing is configured to pass through the opening in the apron so as to project from a second side of the apron opposite the first side.
[0016] Un tel dispositif peut donc être inséré dans le véhicule d’un seul tenant, d’un seul bloc, et non en plusieurs parties à assembler par la suite. Ceci permet de limiter les étapes d’assemblage du boîtier et de montage au sein du véhicule. [0016] Such a device can therefore be inserted into the vehicle in one piece, in one piece, and not in several parts to be assembled subsequently. This makes it possible to limit the steps of assembling the box and mounting it within the vehicle.
[0017] De plus, la première partie, plus encombrante, est destinée à être située du côté du premier côté du tablier, tel que le compartiment moteur, et seule la deuxième partie permettant la distribution du flux d’air dans l’habitacle est destinée à être située du deuxième côté du tablier, tel que l’habitacle. [0017] Furthermore, the first part, which is more bulky, is intended to be located on the side of the first side of the apron, such as the engine compartment, and only the second part allowing the distribution of the air flow in the passenger compartment is intended to be located on the second side of the apron, such as the passenger compartment.
[0018] Ledit dispositif peut en outre comporter une ou plusieurs caractéristiques suivantes décrites ci-après, prises séparément ou en combinaison. [0018] Said device may also include one or more of the following characteristics described below, taken separately or in combination.
[0019] Ledit dispositif peut comporter au moins un volet de répartition agencé dans le conduit de distribution.
[0020] Ledit dispositif peut comporter au moins un ensemble d’entraînement dudit volet configuré pour entraîner en déplacement ledit volet de manière à régler la distribution du flux d’air à travers la sortie d’air. Said device may include at least one distribution flap arranged in the distribution conduit. [0020] Said device may comprise at least one drive assembly for said flap configured to drive said flap in movement so as to adjust the distribution of the air flow through the air outlet.
[0021] L’ensemble d’entraînement du volet de répartition comporte notamment au moins un actionneur agencé dans la première partie du boîtier. The distribution flap drive assembly comprises in particular at least one actuator arranged in the first part of the housing.
[0022] L’ actionneur ainsi destiné à être situé du premier côté, tel que le côté compartiment moteur, n’a pas à traverser le tablier. Ceci permet de réduire l’ouverture dans le tablier et de limiter les fuites acoustiques. [0022] The actuator thus intended to be located on the first side, such as the engine compartment side, does not have to pass through the apron. This makes it possible to reduce the opening in the apron and limit acoustic leaks.
[0023] Selon un mode de réalisation, l’ensemble d’entraînement du volet de répartition comporte au moins un organe de liaison relié mécaniquement audit volet et à F actionneur. According to one embodiment, the distribution flap drive assembly comprises at least one connecting member mechanically connected to said flap and to F actuator.
[0024] L’organe de liaison peut être disposé au moins partiellement dans la deuxième partie du boîtier. The connecting member can be arranged at least partially in the second part of the housing.
[0025] Le boîtier est par exemple configuré pour être solidarisé à une unique face du tablier. La première partie du boîtier peut comprendre au moins un organe de fixation au tablier. [0025] The housing is for example configured to be secured to a single face of the apron. The first part of the housing may comprise at least one member for fixing to the apron.
[0026] Ledit dispositif peut comporter au moins un échangeur thermique agencé dans la première partie du boîtier. Ledit dispositif peut comporter plusieurs échangeurs thermiques agencés dans la première partie du boîtier. Said device may include at least one heat exchanger arranged in the first part of the housing. Said device may include several heat exchangers arranged in the first part of the housing.
[0027] La première partie du boîtier peut présenter une entrée d’air extérieur et/ou une entrée d’air de recyclage pour un flux d’air en provenance de l’habitacle du véhicule. The first part of the housing may have an outside air inlet and/or a recycling air inlet for an air flow coming from the passenger compartment of the vehicle.
[0028] L’invention concerne également un véhicule notamment automobile comportant un compartiment moteur et un habitacle, séparés par un tablier comprenant au moins une ouverture. Le véhicule comporte au moins un dispositif de chauffage, ventilation et/ou climatisation, tel que défini précédemment. The invention also relates to a vehicle, in particular an automobile, comprising an engine compartment and a passenger compartment, separated by an apron comprising at least one opening. The vehicle includes at least one heating, ventilation and/or air conditioning device, as defined above.
[0029] La première partie et la deuxième partie du boîtier sont agencées de part et d’autre du tablier. Le boîtier est configuré pour être monté d’un seul tenant dans le véhicule et uniquement depuis un premier côté du tablier, la deuxième partie du boîtier étant configurée pour traverser l’ouverture dans le tablier de manière à faire saillie d’un deuxième côté du tablier opposé au premier côté. The first part and the second part of the housing are arranged on either side of the apron. The housing is configured to be mounted integrally in the vehicle and only from a first side of the apron, the second part of the housing being configured to pass through the opening in the apron so as to project from a second side of the apron apron opposite the first side.
[0030] Le véhicule peut en outre comporter une ou plusieurs caractéristiques suivantes décrites ci-après, prises séparément ou en combinaison.
[0031] Le compartiment moteur du véhicule est par exemple du premier côté du tablier. The vehicle may also include one or more of the following characteristics described below, taken separately or in combination. [0031] The engine compartment of the vehicle is for example on the first side of the apron.
[0032] L’habitacle est par exemple du deuxième côté du tablier. [0032] The passenger compartment is for example on the second side of the apron.
[0033] Le tablier peut comporter une première ouverture traversée par la deuxième partie du boîtier et une deuxième ouverture disposée en regard d’une entrée d’air de recyclage de la première partie du boîtier. The apron may include a first opening through which the second part of the housing passes and a second opening placed opposite a recycling air inlet of the first part of the housing.
[0034] L’invention concerne encore un procédé de montage d’un dispositif de chauffage, ventilation et/ou climatisation tel que défini précédemment dans un véhicule notamment automobile. The invention also relates to a method of mounting a heating, ventilation and/or air conditioning device as defined above in a vehicle, particularly an automobile.
[0035] Ledit procédé comporte les étapes suivantes : insertion du boîtier d’un seul tenant dans le véhicule, uniquement par un premier côté du tablier, de sorte que la deuxième partie du boîtier traverse l’ouverture dans le tablier de manière à faire saillie d’un deuxième côté du tablier opposé au premier côté et que la première partie du boîtier soit agencée du premier côté du tablier, et fixation de la première partie du boîtier au tablier. [0035] Said method comprises the following steps: insertion of the housing in one piece into the vehicle, only through a first side of the apron, so that the second part of the housing passes through the opening in the apron so as to project of a second side of the apron opposite the first side and that the first part of the housing is arranged on the first side of the apron, and fixing the first part of the housing to the apron.
[0036] Le procédé peut comporter une étape préliminaire d’assemblage du boîtier dudit dispositif, de manière à former un ensemble unitaire. The method may include a preliminary step of assembling the housing of said device, so as to form a unitary assembly.
[0037] D’autres avantages et caractéristiques 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 : Other advantages and characteristics of the invention will appear more clearly on reading the following description given by way of illustrative and non-limiting example, and the appended drawings among which:

[0042] Les réalisations suivantes sont des exemples. Bien que la description se réfère à un ou plusieurs modes de réalisation, ceci ne signifie pas nécessairement que chaque référence concerne le même mode de réalisation, ou que les caractéristiques s’appliquent
uniquement à un seul mode de réalisation. De simples caractéristiques de différents modes de réalisation peuvent également être combinées ou interchangées pour fournir d’autres réalisations. [0042] The following achievements are examples.

[0044] De plus, dans la description, les termes amont et aval sont définis en référence à l’écoulement d’un flux d’air circulant au sein d’un dispositif de chauffage, ventilation et/ou climatisation. [0044] Furthermore, in the description, the terms upstream and downstream are defined with reference to the flow of an air flow circulating within a heating, ventilation and/or air conditioning device.
[0045] Dispositif de chauffage, ventilation et/ou climatisation [0045] Heating, ventilation and/or air conditioning device
[0046] En référence aux figures 1 et 2, l’invention concerne un dispositif de chauffage, ventilation et/ou climatisation 1, désigné par la suite par dispositif 1. [0046] With reference to Figures 1 and 2, the invention relates to a heating, ventilation and/or air conditioning device 1, hereinafter designated as device 1.
[0047] Le dispositif 1 est destiné à être installé dans un véhicule notamment automobile, non représenté sur les figures. Le véhicule comporte un compartiment moteur M et un habitacle H. Le compartiment moteur M et un habitacle H sont séparés par un panneau couramment nommé tablier 3. Le compartiment moteur M est par exemple d’un premier côté du tablier 3 et l’habitacle H d’un deuxième côté du tablier 3, opposé au premier côté. Le tablier 3 comporte une ouverture 31. Cette ouverture 31 est destinée à être traversée par une partie du dispositif 1, notamment de distribution d’air à destination de l’habitacle H, comme décrit par la suite. L’invention concerne aussi un tel véhicule comportant le dispositif 1. The device 1 is intended to be installed in a vehicle, particularly an automobile, not shown in the figures. The vehicle comprises an engine compartment M and a passenger compartment H. The engine compartment M and a passenger compartment H are separated by a panel commonly called apron 3. The engine compartment M is for example on a first side of the apron 3 and the passenger compartment H on a second side of the apron 3, opposite the first side. The apron 3 has an opening 31. This opening 31 is intended to be crossed by a part of the device 1, in particular for distributing air to the passenger compartment H, as described below. The invention also relates to such a vehicle comprising device 1.
[0048] Un trièdre XYZ est schématisé sur la figure 1. L’axe X est un axe longitudinal du dispositif 1. Cet axe X peut correspondre à l’axe longitudinal avant/arrière du véhicule, c'est-à-dire selon la longueur du véhicule, lorsque le dispositif 1 est monté au sein du véhicule. L’axe Y est un axe transversal du dispositif 1. Cet axe Y peut correspondre à l’axe transversal droite/gauche du véhicule, c'est-à-dire selon la largeur du véhicule, lorsque le dispositif 1 est monté au sein du véhicule. L’axe Z peut coïncider avec l’axe vertical haut/bas du véhicule, c'est-à-dire selon la hauteur du véhicule, lorsque le
dispositif 1 est monté au sein du véhicule. Les axes X, Y, Z, sont perpendiculaires les uns aux autres. [0048] An XYZ trihedron is schematized in Figure 1. The X axis is a longitudinal axis of the device 1. This X axis can correspond to the front/rear longitudinal axis of the vehicle, that is to say according to the length of the vehicle, when the device 1 is mounted within the vehicle. The Y axis is a transverse axis of the device 1. This Y axis can correspond to the right/left transverse axis of the vehicle, that is to say according to the width of the vehicle, when the device 1 is mounted within the vehicle. The Z axis can coincide with the vertical up/down axis of the vehicle, that is to say according to the height of the vehicle, when the device 1 is mounted within the vehicle. The X, Y, Z axes are perpendicular to each other.
[0049] Le dispositif 1 comprend un boîtier 5. Le boîtier 5 peut être monobloc (en une unique pièce), ou comporter plusieurs modules assemblés les uns aux autres. Une fois les modules assemblés, le boîtier 5 forme un seul bloc. The device 1 comprises a housing 5. The housing 5 can be in one piece (in a single piece), or comprise several modules assembled together. Once the modules are assembled, the box 5 forms a single block.
[0050] Lors de l’installation au sein du véhicule, le boîtier 5 est monté d’un seul tenant dans le véhicule. En particulier, le boîtier 5 est destiné à être monté dans le véhicule uniquement le premier côté du tablier 3, notamment depuis le compartiment moteur M. [0050] During installation within the vehicle, the box 5 is mounted in one piece in the vehicle. In particular, the housing 5 is intended to be mounted in the vehicle only the first side of the apron 3, in particular from the engine compartment M.
[0051] Les parois du boîtier 5 délimitent un volume interne. Ce volume interne comprend au moins un canal d’écoulement pour un flux air destiné à être distribué dans l’habitacle H. Le canal d’écoulement permet de véhiculer un flux d’air depuis au moins une entrée d’air 7, 7’ permettant l’admission du flux d’air dans le boîtier 5 jusqu’à au moins une sortie d’air 9a, 9b débouchant dans l’habitacle H lorsque le dispositif 1 est monté dans le véhicule. The walls of the housing 5 delimit an internal volume. This internal volume comprises at least one flow channel for an air flow intended to be distributed in the passenger compartment H. The flow channel makes it possible to convey an air flow from at least one air inlet 7, 7' allowing the air flow to be admitted into the housing 5 up to at least one air outlet 9a, 9b opening into the passenger compartment H when the device 1 is mounted in the vehicle.
[0052] L’entrée d’air 7, 7’ est formée par une ouverture dans le boîtier 5. Il peut s’agir d’une entrée d’air 7 extérieur. En variante ou en complément, le boîtier 5 peut comporter au moins une ouverture définissant une entrée d’air 7’ dite de recyclage, pour un flux d’air en provenance de l’habitacle. Un volet, dit volet d’admission d’air, peut être agencé entre les deux ouvertures pour obturer au moins partiellement chacune. The air inlet 7, 7' is formed by an opening in the housing 5. It may be an exterior air inlet 7. Alternatively or in addition, the housing 5 may include at least one opening defining a so-called recycling air inlet 7', for a flow of air coming from the passenger compartment. A shutter, called an air intake shutter, can be arranged between the two openings to at least partially close each one.
[0053] Dans l’exemple particulier illustré, l’entrée d’air 7 extérieur est prévue dans une région basse ou inférieure du boîtier 5. De façon alternative, l’entrée d’air 7 extérieur peut être agencée au niveau d’une région haute ou supérieure du boîtier 5. L’entrée d’air 7’ de recyclage est par exemple agencée au niveau de la région haute ou supérieure du boîtier 5. La région inférieure et la région supérieure sont définies par rapport à l’axe Z du dispositif 1, correspondant par exemple à l’axe vertical du véhicule à l’état monté du dispositif 1 dans le véhicule. [0053] In the particular example illustrated, the exterior air inlet 7 is provided in a lower or lower region of the housing 5. Alternatively, the exterior air inlet 7 can be arranged at the level of a upper or upper region of the housing 5. The recycling air inlet 7' is for example arranged at the upper or upper region of the housing 5. The lower region and the upper region are defined relative to the Z axis of the device 1, corresponding for example to the vertical axis of the vehicle in the mounted state of the device 1 in the vehicle.
[0054] Afin de permettre à l’air de recyclage d’accéder à l’entrée d’air 7’ de recyclage, le tablier 3 peut comprendre en outre une deuxième ouverture ménagée en regard de cette entrée d’air 7 de recyclage. Dans ce cas, l’ouverture destinée à être traversée par une partie du dispositif 1 est nommée première ouverture 31.
[0055] Au moins un filtre peut être agencé dans le boîtier 5, en aval d’une entrée d’air, de manière à être traversé par le flux d’air. Dans l’exemple illustré, au moins un filtre 8 est agencé en aval de l’entrée d’air 7 extérieur. Une trappe d’accès 10 peut être prévue sur le boîtier 5 pour chaque filtre 8, afin de pouvoir accéder et remplacer le ou les filtres 8. [0054] In order to allow the recycling air to access the recycling air inlet 7', the apron 3 may further comprise a second opening facing this recycling air inlet 7. In this case, the opening intended to be passed through by a part of the device 1 is called first opening 31. [0055] At least one filter can be arranged in the housing 5, downstream of an air inlet, so as to be crossed by the air flow. In the example illustrated, at least one filter 8 is arranged downstream of the exterior air inlet 7. An access hatch 10 can be provided on the housing 5 for each filter 8, in order to be able to access and replace the filter(s) 8.
[0056] Le flux d’air est introduit dans le boîtier 5 et dirigé au moyen d’un pulseur 11. Le volet d’admission d’air est par exemple agencé en amont du pulseur 11 selon le sens d’écoulement du flux d’air. Le pulseur 11 comprend notamment un moteur et une roue, telle qu’une roue à aubes ou à pales. Le pulseur 11 est monté mobile en rotation autour d’un axe. Cet axe de rotation du pulseur peut être vertical ou en variante horizontal, à l’état monté du boîtier 5 dans le véhicule. The air flow is introduced into the housing 5 and directed by means of a blower 11. The air intake flap is for example arranged upstream of the blower 11 according to the direction of flow of the flow d 'air. The blower 11 comprises in particular a motor and a wheel, such as a paddle wheel or blades. The blower 11 is mounted to rotate around an axis. This axis of rotation of the blower can be vertical or, alternatively, horizontal, in the mounted state of the housing 5 in the vehicle.
[0057] Un ou plusieurs moyens de traitement thermique du flux d’air, tels que des échangeurs thermiques 13, 15 peuvent être logés dans le boîtier 5. Dans l’exemple illustré deux échangeurs thermique 13, 15 sont représentés. Ce nombre n’est pas limitatif. Un premier échangeur thermique 13 est par exemple un évaporateur, destiné à refroidir et déshumidifier le flux d’air circulant au sein du boîtier 5. Un deuxième échangeur thermique 15 est par exemple un radiateur, destiné à réchauffer au moins une partie du flux d’air circulant au sein du boîtier 5. Le deuxième échangeur thermique 15 est agencé en aval du premier échangeur thermique 13, par rapport à l’écoulement du flux d’air. Le deuxième échangeur thermique 15 peut éventuellement être couplé à un autre échangeur thermique, tel qu’un radiateur par exemple électrique. One or more means of heat treatment of the air flow, such as heat exchangers 13, 15 can be housed in the housing 5. In the example illustrated two heat exchangers 13, 15 are represented. This number is not limiting. A first heat exchanger 13 is for example an evaporator, intended to cool and dehumidify the air flow circulating within the housing 5. A second heat exchanger 15 is for example a radiator, intended to heat at least part of the air flow. air circulating within the housing 5. The second heat exchanger 15 is arranged downstream of the first heat exchanger 13, relative to the flow of the air flow. The second heat exchanger 15 can optionally be coupled to another heat exchanger, such as an electric radiator for example.
[0058] Le flux d’air refroidi par le premier échangeur thermique 13, peut être guidé au sein du canal d’écoulement vers le deuxième échangeur thermique 15. Pour garantir que le flux d’air froid, issu du premier échangeur thermique 13, ne soit pas thermiquement contaminé par le deuxième échangeur thermique 15, le dispositif 1 peut comprendre un canal de contournement 17 du deuxième échangeur thermique 15. Ainsi, le flux d’air froid, ayant traversé le premier échangeur thermique 13, circule soit à travers le deuxième échangeur thermique 15 pour être réchauffé, soit contourne le deuxième échangeur thermique 15 par le canal de contournement 17 afin de conserver sa basse température. [0058] The flow of air cooled by the first heat exchanger 13 can be guided within the flow channel towards the second heat exchanger 15. To guarantee that the flow of cold air, coming from the first heat exchanger 13, is not thermally contaminated by the second heat exchanger 15, the device 1 can comprise a bypass channel 17 of the second heat exchanger 15. Thus, the flow of cold air, having passed through the first heat exchanger 13, circulates either through the second heat exchanger 15 to be heated, or bypasses the second heat exchanger 15 via the bypass channel 17 in order to maintain its low temperature.
[0059] Le dispositif 1 peut comprendre un ou plusieurs volets de mixage 19 permettant de réguler la proportion de flux d’air froid passant par le deuxième échangeur thermique 15 et la proportion de flux d’air froid passant par le canal de contournement 17.
[0060] Les volets de mixage 19 peuvent être de différents types. À titre d’exemple, il peut s’agir de volets de type drapeau, correspondant à une porte avec un arbre de rotation agencée à une des extrémités de la porte, ou de type coulissant aussi connu sous le nom anglais « sliding door », correspondant à une porte coulissante sur laquelle est agencée au moins une crémaillère, ou encore de type papillon, correspondant à un volet avec un arbre de rotation et une ou deux pales agencées de part et d’autre de l’arbre de rotation, comme dans l’exemple illustré. Les volets de mixage 19 tel qu’illustrés sont agencés entre le premier échangeur thermique 13 et le deuxième échangeur thermique 15. The device 1 may comprise one or more mixing flaps 19 making it possible to regulate the proportion of cold air flow passing through the second heat exchanger 15 and the proportion of cold air flow passing through the bypass channel 17. The mixing flaps 19 can be of different types. For example, these may be flag type shutters, corresponding to a door with a rotation shaft arranged at one of the ends of the door, or sliding type also known under the English name "sliding door". corresponding to a sliding door on which at least one rack is arranged, or of the butterfly type, corresponding to a shutter with a rotation shaft and one or two blades arranged on either side of the rotation shaft, as in the example illustrated. The mixing flaps 19 as illustrated are arranged between the first heat exchanger 13 and the second heat exchanger 15.
[0061] Le pulseur 11 permet d’acheminer le flux d’air depuis au moins une entrée d’air 7, 7’ jusqu’à au moins une sortie d’air 9a, 9b, notamment après conditionnement thermiquement de ce flux d’air par le ou les échangeurs thermique 13, 15. [0061] The blower 11 makes it possible to route the air flow from at least one air inlet 7, 7' to at least one air outlet 9a, 9b, in particular after thermal conditioning of this air flow. air through the heat exchanger(s) 13, 15.
[0062] De plus, le boîtier 5 définit une première partie 5A et une deuxième partie 5B. La première partie 5 A et la deuxième partie 5B du boîtier 5 sont agencées de part et d’autre du tablier 3 à l’état monté du boîtier 5 dans le véhicule. In addition, the housing 5 defines a first part 5A and a second part 5B. The first part 5 A and the second part 5B of the housing 5 are arranged on either side of the apron 3 in the mounted state of the housing 5 in the vehicle.
[0063] Ces deux parties 5A, 5B forment un bloc unitaire monté d’un seul tenant dans le véhicule. Il ne s’agit pas d’un boîtier coupé en deux, et dont chaque partie est insérée indépendamment au sein du véhicule, en plusieurs étapes. Le boîtier 5 selon le mode de réalisation décrit, est monté dans son ensemble, d’un seul bloc, au sein du véhicule, via le premier côté du tablier 3, tel que le compartiment moteur. [0063] These two parts 5A, 5B form a unitary block mounted in one piece in the vehicle. It is not a case cut in two, and each part of which is inserted independently into the vehicle, in several stages. The housing 5 according to the embodiment described, is mounted as a whole, in one piece, within the vehicle, via the first side of the apron 3, such as the engine compartment.
[0064] En outre, lors de l’installation du boîtier 5 dans le véhicule, depuis le premier côté du tablier 3, la deuxième partie 5B du boîtier 5 traverse l’ouverture 31 (ou première ouverture 31) dans le tablier 3. De la sorte, la deuxième partie 5B fait saillie du deuxième côté du tablier 3, par exemple du côté habitacle H. La première partie 5 A, quant à elle, est agencée du premier côté du tablier 3, par exemple du côté compartiment moteur M. [0064] Furthermore, when installing the housing 5 in the vehicle, from the first side of the apron 3, the second part 5B of the housing 5 passes through the opening 31 (or first opening 31) in the apron 3. In this way, the second part 5B projects from the second side of the apron 3, for example on the passenger compartment side H. The first part 5 A, for its part, is arranged on the first side of the apron 3, for example on the engine compartment side M.
[0065] Lors de l’installation dans le véhicule, le boîtier 5 peut être solidarisé à une unique face du tablier 3. Il s’agit notamment d’une face du premier côté du tablier 3, par exemple le compartiment moteur M. Autrement dit, à l’état monté du dispositif 1 dans le véhicule, le boîtier 5 peut n’être fixé au tablier 3 que du premier côté de celui-ci, tout en s’étendant de part et d’autre du tablier 3. [0065] During installation in the vehicle, the housing 5 can be secured to a single face of the apron 3. This concerns in particular a face of the first side of the apron 3, for example the engine compartment M. Otherwise said, in the mounted state of the device 1 in the vehicle, the housing 5 can only be fixed to the apron 3 on the first side of the latter, while extending on either side of the apron 3.
[0066] Le boîtier 5 et plus précisément la première partie 5A du boîtier 5 comprend à cet effet au moins un organe (non représenté) de fixation au tablier 3. Un tel organe de
fixation est notamment destiné à coopérer avec un élément ou organe complémentaire agencé sur le tablier 3. Tout type d’organes ou d’éléments permettant la fixation du boîtier 5 au tablier 3 peuvent être envisagés. [0066] The housing 5 and more precisely the first part 5A of the housing 5 comprises for this purpose at least one member (not shown) for fixing to the apron 3. Such a member of fixing is in particular intended to cooperate with a complementary element or member arranged on the apron 3. Any type of member or element allowing the fixing of the housing 5 to the apron 3 can be envisaged.
[0067] En outre, la première partie 5 A du boîtier 5 présente l’entrée d’air ou les entrées d’air 7 extérieur et 7’ de recyclage. [0067] Furthermore, the first part 5 A of the housing 5 presents the air inlet or the exterior air inlets 7 and 7' of recycling.
[0068] La première partie 5A comporte avantageusement le ou les filtres 8 éventuellement associés à chaque entrée d’air 7, 7’. De façon complémentaire, elle comporte la trappe d’accès 10 pour chaque filtre 8. The first part 5A advantageously comprises the filter(s) 8 possibly associated with each air inlet 7, 7'. In addition, it includes access hatch 10 for each filter 8.
[0069] La première partie 5A du boîtier 5 peut comporter également le pulseur 11. Elle peut comporter notamment une volute correspondant à une partie du boîtier en spirale, permettant de véhiculer le flux d’air entrant au sein du boîtier jusqu’au premier échangeur thermique 13. [0069] The first part 5A of the housing 5 may also include the blower 11. It may include in particular a volute corresponding to a part of the spiral housing, making it possible to convey the flow of air entering the housing to the first exchanger thermal 13.
[0070] La première partie 5A du boîtier 5 peut loger le ou les échangeurs thermique 13, 15, et le ou les éventuels volets de mixage 19. Ainsi, tous les échangeurs thermiques 13, 15 sont agencés d’un même côté du tablier 3, notamment du côté compartiment moteur M. The first part 5A of the housing 5 can house the heat exchanger(s) 13, 15, and the possible mixing flap(s) 19. Thus, all the heat exchangers 13, 15 are arranged on the same side of the apron 3 , particularly on the M engine compartment side.
[0071] La première partie 5 A définit également une chambre 21 destinée à être traversée par le flux d’air, qui est donc en communication fluidique avec l’entrée d’air, telle que l’entrée d’air 7 extérieur et/ou l’entrée d’air 7’ de recyclage. Une telle chambre 21 est située en aval du ou des échangeurs thermiques 13, 15. Il s’agit par exemple d’une chambre de mixage 21. En fonctionnement du dispositif 1, les flux d’air chaud et/ou froid en sortie des échangeurs thermique 13, 15 peuvent être guidés vers la chambre 21 pour y être mélangés avant distribution dans l’habitacle à une température de consigne. The first part 5 A also defines a chamber 21 intended to be traversed by the air flow, which is therefore in fluid communication with the air inlet, such as the exterior air inlet 7 and/or or the 7' recycling air inlet. Such a chamber 21 is located downstream of the heat exchanger(s) 13, 15. It is for example a mixing chamber 21. In operation of the device 1, the hot and/or cold air flows leaving the heat exchangers 13, 15 can be guided towards the chamber 21 to be mixed there before distribution in the passenger compartment at a set temperature.
[0072] La première partie 5A forme ainsi une partie d’entrée d’air et de conditionnement thermique. [0072] The first part 5A thus forms an air inlet and thermal conditioning part.
[0073] La deuxième partie 5B du boîtier 5 comporte au moins un conduit de distribution 23 d’air. La deuxième partie 5B forme ainsi une partie de distribution. The second part 5B of the housing 5 comprises at least one air distribution conduit 23. The second part 5B thus forms a distribution part.
[0074] Dans l’exemple illustré, quatre conduits de distribution 23 sont représentés. Bien entendu, ce nombre n’est pas limitatif, plus ou moins de conduits de distribution 23 peuvent être prévus.
[0075] Selon un exemple d’agencement particulier, représenté sur les figures 1 et 2, au moins un conduit de distribution 23 peut être agencé dans la région haute ou supérieure du boîtier 5. Le ou les conduits de distribution 23 sont dans cet exemple agencés au niveau de la région du boîtier 5 opposée à l’entrée d’air 7 extérieur. [0074] In the example illustrated, four distribution conduits 23 are shown. Of course, this number is not limiting, more or fewer distribution conduits 23 can be provided. [0075] According to an example of a particular arrangement, shown in Figures 1 and 2, at least one distribution conduit 23 can be arranged in the upper or upper region of the housing 5. The distribution conduit(s) 23 are in this example arranged at the region of the housing 5 opposite the exterior air inlet 7.
[0076] Par ailleurs, le ou les conduits de distribution 23 sont disposés en aval de la chambre 21 selon l’écoulement du flux d’air. [0076] Furthermore, the distribution conduit(s) 23 are arranged downstream of the chamber 21 according to the flow of the air flow.
[0077] Le ou les conduits de distribution 23 se terminent chacun par une sortie d’air 9a, 9b respective. Les sorties d’air 9a, 9b débouchent dans au moins une zone de l’habitacle du véhicule lorsque le dispositif 1 est monté dans le véhicule. Dans l’exemple illustré, au moins une sortie d’air 9a dite de ventilation et au moins une autre sortie d’air 9b dite pieds sont prévues. La ou les sorties d’air 9a de ventilation sont destinées à déboucher dans l’habitacle, par exemple sensiblement au niveau des bustes des passagers du véhicule et/ou de leurs têtes. La ou les sorties d’air 9b pieds sont destinées à déboucher dans l’habitacle au niveau des pieds des passagers du véhicule. Il peut s’agir de buses, telles qu’une buse de dégivrage permettant de désembuer le pare-brise, une buse de ventilation latérale/centrale permettant de refroidir/réchauffer les passagers du véhicule, une buse pied permettant de refroidir/réchauffer les pieds des passagers du véhicule. Dans ce cas, le ou les conduits de distribution 23 s’étendent depuis la chambre 21 jusqu’à une buse respective débouchant dans l’habitacle. The distribution conduit(s) 23 each end in a respective air outlet 9a, 9b. The air outlets 9a, 9b open into at least one area of the vehicle passenger compartment when the device 1 is mounted in the vehicle. In the example illustrated, at least one air outlet 9a called ventilation and at least one other air outlet 9b called feet are provided. The ventilation air outlet(s) 9a are intended to open into the passenger compartment, for example substantially at the level of the busts of the passengers of the vehicle and/or their heads. The air outlet(s) 9b feet are intended to open into the passenger compartment at the level of the feet of the passengers of the vehicle. These may be nozzles, such as a defroster nozzle for defogging the windshield, a side/central ventilation nozzle for cooling/heating vehicle passengers, a foot nozzle for cooling/warming the feet passengers of the vehicle. In this case, the distribution conduit(s) 23 extend from the chamber 21 to a respective nozzle opening into the passenger compartment.
[0078] Un volet 25 de distribution ou de répartition peut être agencé dans le ou les conduits de distribution 23. Plus précisément, un volet 25 de distribution ou de répartition peut être agencé à l’entrée du ou de chaque conduit de distribution 23. Chaque volet 25 de répartition est configuré pour passer d’une position où il obture intégralement l’entrée du conduit de distribution 23 correspondant à une position où il permet au flux d’air de circuler intégralement au sein du conduit de distribution 23. Chaque volet 25 de répartition est apte à adopter toute position intermédiaire. [0078] A distribution or distribution flap 25 can be arranged in the distribution conduit(s) 23. More precisely, a distribution or distribution flap 25 can be arranged at the entrance to the distribution conduit(s) 23. Each distribution flap 25 is configured to move from a position where it completely closes the inlet of the distribution duct 23 corresponding to a position where it allows the air flow to circulate entirely within the distribution duct 23. Each flap 25 distribution is able to adopt any intermediate position.
[0079] Les volets 25 de répartition peuvent être de différents types. À titre d’exemple, un ou plusieurs volets 25 de répartition peuvent être de type drapeau, ou de type coulissant, ou encore de type papillon, comme dans l’exemple illustré. The distribution flaps 25 can be of different types. For example, one or more distribution flaps 25 can be of the flag type, or of the sliding type, or even of the butterfly type, as in the example illustrated.
[0080] Pour commander les volets 25 de répartition, au moins un ensemble d’entraînement ou de cinématique, est prévu. Un ensemble d’entraînement peut être associé à chaque
volet 25 de répartition pour l’entraîner en déplacement de manière à régler la distribution du flux d’air à travers la sortie d’air 9a, 9b correspondante. L’ensemble d’entraînement, la cinématique, est principalement du premier côté du tablier 3, notamment du côté compartiment moteur M. [0080] To control the distribution flaps 25, at least one drive or kinematic assembly is provided. A training set can be associated with each distribution flap 25 to cause it to move so as to adjust the distribution of the air flow through the corresponding air outlet 9a, 9b. The drive assembly, the kinematics, is mainly on the first side of the apron 3, in particular on the engine compartment side M.
[0081] En particulier, chaque ensemble d’entraînement comporte au moins un actionneur 27. [0081] In particular, each drive assembly comprises at least one actuator 27.
[0082] Les actionneurs 27 sont agencés dans la première partie 5 A du boîtier 5. À l’état monté du dispositif 1 dans le véhicule, les actionneurs 27 sont donc du premier côté du tablier 3, notamment du côté compartiment moteur M. Cela permet d’éviter que les actionneurs 27 n’aient à traverser l’ouverture (ou première ouverture) 31 du tablier 3, lors de l’insertion du boîtier 5 dans le véhicule. La taille de l’ouverture 31 dans le tablier 3 peut ainsi être diminuée au maximum, sans avoir à réduire la taille des conduits de distribution 23 et des sorties d’air 9a, 9b. Ceci est avantageux en termes d’encombrement et de performances aérauliques, et contribue également à limiter la transmission acoustique entre le compartiment moteur M et l’habitacle H. [0082] The actuators 27 are arranged in the first part 5 A of the housing 5. In the mounted state of the device 1 in the vehicle, the actuators 27 are therefore on the first side of the apron 3, in particular on the engine compartment side M. This prevents the actuators 27 from having to pass through the opening (or first opening) 31 of the apron 3, when inserting the housing 5 into the vehicle. The size of the opening 31 in the apron 3 can thus be reduced as much as possible, without having to reduce the size of the distribution ducts 23 and the air outlets 9a, 9b. This is advantageous in terms of space requirement and aeraulic performance, and also helps to limit acoustic transmission between the engine compartment M and the passenger compartment H.
[0083] En référence à la figure 3, l’ensemble d’entraînement peut comporter en outre au moins un organe de liaison 29 relié mécaniquement au volet 25 de répartition et à l’actionneur 27 correspondants. Il peut s’agir par exemple d’une platine, de bielles, de tringles, pour commander le volet 25 de répartition. Le ou les organes de liaison 29 sont dans l’exemple illustré sur la figure 3, disposés en partie dans la deuxième partie 5B du boîtier 5. Une autre partie non visible des organes de liaison 29 peut s’étendre dans la première partie 5 A du boîtier 5. [0083] With reference to Figure 3, the drive assembly may further comprise at least one connecting member 29 mechanically connected to the distribution flap 25 and to the corresponding actuator 27. It may for example be a plate, connecting rods, rods, to control the distribution flap 25. The connecting member(s) 29 are in the example illustrated in Figure 3, arranged partly in the second part 5B of the housing 5. Another non-visible part of the connecting members 29 can extend into the first part 5A of the housing 5.
[0084] Procédé de montage du dispositif dans un véhicule [0084] Method of mounting the device in a vehicle
[0085] Le dispositif 1 peut être monté dans un véhicule selon un procédé de montage comportant les étapes ci-après, en référence aux figures 1 à 3. [0085] The device 1 can be mounted in a vehicle according to an assembly method comprising the steps below, with reference to Figures 1 to 3.
[0086] Lors d’au moins une étape préliminaire, le boîtier 5 du dispositif 1 peut être assemblé de manière à former un ensemble unitaire, en particulier lorsque le boîtier 5 comporte plusieurs modules. Les différents éléments du dispositif 1, tels que le ou les filtres 8, le ou les échangeurs thermiques 13, 15, le ou les volets 19, 25 peuvent être montés à l’intérieur du boîtier 5. [0086] During at least one preliminary step, the housing 5 of the device 1 can be assembled so as to form a unitary assembly, in particular when the housing 5 comprises several modules. The different elements of the device 1, such as the filter(s) 8, the heat exchanger(s) 13, 15, the shutter(s) 19, 25 can be mounted inside the housing 5.
[0087] Le procédé comporte une étape d’insertion du boîtier 5 d’un seul tenant dans le véhicule. Cette insertion se fait uniquement par le premier côté du tablier 3, notamment
du côté compartiment moteur M. Durant cette insertion, la deuxième partie 5B du boîtier 5 traverse l’ouverture 31 (ou première ouverture) dans le tablier 3, et fait saillie du deuxième côté du tablier 3, notamment du côté habitacle H. La première partie 5 A du boîtier 5 est agencée du premier côté du tablier 3, notamment du côté compartiment moteur M. [0087] The method includes a step of inserting the housing 5 in one piece into the vehicle. This insertion is done only by the first side of the apron 3, in particular on the engine compartment side M. During this insertion, the second part 5B of the housing 5 passes through the opening 31 (or first opening) in the apron 3, and projects from the second side of the apron 3, in particular on the passenger compartment side H. The first part 5 A of the housing 5 is arranged on the first side of the apron 3, in particular on the engine compartment M side.
[0088] Le procédé comporte une étape suivante de fixation du boîtier 5, et plus précisément de la première partie 5A du boîtier 5, au tablier 3. Cette fixation peut se faire par complémentarité d’organes de fixation portés d’une part par le boîtier 5, notamment sur sa première partie 5 A, et d’autre part par le tablier 3. [0089] Ainsi, la première partie 5A du boîtier 5, comprenant avantageusement l’entrée d’air 7 extérieur et/ou 7’ de recyclage, les échangeurs thermiques 13, 15 et les éventuels volets de mixage 19, ainsi que les actionneurs 27 des volets 25 de répartition, est agencée d’un côté, ou d’une face, du tablier 3, notamment du côté compartiment moteur M. A l’inverse, la deuxième partie 5B du boîtier 5, comprenant les conduits de distribution 23 et les volets 25 associés de répartition, ainsi qu’une partie de la cinématique, tels qu’un ou plusieurs organes de liaison 29, est agencée de l’autre côté ou face du tablier 3. [0088] The method comprises a following step of fixing the housing 5, and more precisely the first part 5A of the housing 5, to the apron 3. This fixing can be done by complementarity of fixing members carried on the one hand by the housing 5, in particular on its first part 5 A, and on the other hand by the apron 3. [0089] Thus, the first part 5A of the housing 5, advantageously comprising the exterior air inlet 7 and/or 7' of recycling, the heat exchangers 13, 15 and the possible mixing flaps 19, as well as the actuators 27 of the distribution flaps 25, is arranged on one side, or on one face, of the apron 3, in particular on the engine compartment side M Conversely, the second part 5B of the housing 5, comprising the distribution conduits 23 and the associated distribution flaps 25, as well as part of the kinematics, such as one or more connecting members 29, is arranged on the other side or face of the apron 3.
[0090] Tous les éléments du dispositif 1 pouvant être délocalisés de l’habitacle H sont placés dans le compartiment moteur M.
[0090] All the elements of device 1 that can be relocated from the passenger compartment H are placed in the engine compartment M.
