Description

Ensemble d'un module d'échange de chaleur et d'au moins un organe électrique.  Set of a heat exchange module and at least one electric member.
La présente invention concerne un ensemble d'un module d'échange de chaleur et d'au moins un organe électrique. Elle trouvera en particulier ses applications dans le domaine des véhicules automobiles. The present invention relates to an assembly of a heat exchange module and at least one electrical member. It will find in particular its applications in the field of motor vehicles.
Il est connu de longue date de refroidir le moteur thermique d'un véhicule automobile à l'aide d'un liquide caloporteur. Après avoir refroidi le moteur, le liquide, chaud, est à son tour refroidi en passant dans un radiateur de refroidissement situé en face avant du véhicule pour être balayé par un flux d'air ambiant passant à travers la calendre du véhicule. Le fonctionnement de nombreux véhicules automobile nécessite encore le refroidissement d'autres fluides tels que l'air de suralimentation en air du moteur, le fluide frigorigène de la boucle de climatisation de l'habitacle du véhicule ou autres.  It has long been known to cool the engine of a motor vehicle with a heat transfer liquid. After cooling the engine, the hot liquid is cooled by passing through a cooling radiator located on the front of the vehicle to be swept by a flow of ambient air passing through the calender of the vehicle. The operation of many motor vehicles still requires the cooling of other fluids such as engine air supercharging air, refrigerant air conditioning loop of the vehicle interior or other.
Comme pour le fluide caloporteur de refroidissement du moteur, certains de ces fluides sont refroidis à l'aide d'un échangeur de chaleur situé en face avant du véhicule pour être balayé par le flux d'air passant à travers la calendre. Pour d'autres, le refroidissement s'effectue par un échange de chaleur avec un liquide caloporteur à son tour refroidi par le flux d'air ambiant traversant la calendre. On parle alors d'échange indirect.  As for the heat transfer fluid of the engine, some of these fluids are cooled using a heat exchanger located on the front of the vehicle to be swept by the air flow passing through the calender. For others, the cooling is done by heat exchange with a coolant liquid in turn cooled by the flow of ambient air through the calender. This is called indirect exchange.
Pour l'échange de chaleur en face avant, il est nécessaire de disposer de groupes moto-ventilateurs afin d'assurer un flux d'air ambiant minimum quand le véhicule est à l'arrêt ou roule à trop faible vitesse. Pour l'échange indirect, il est nécessaire d'utiliser des pompes faisant circuler le liquide caloporteur jusqu'à l'échangeur assurant le refroidissement du fluide en cause.  For heat exchange on the front panel, it is necessary to have motor-fan units in order to ensure a minimum ambient air flow when the vehicle is stationary or is traveling at too slow a speed. For the indirect exchange, it is necessary to use pumps circulating the heat transfer liquid to the exchanger ensuring the cooling of the fluid in question.
Actuellement, l'énergie électrique employée pour l'alimentation d'un organe électrique, qu'il s'agisse par exemple d'un groupe moto ventilateur et/ou des pompes et/ou de tout type d'actionneur électrique, est fournie par un alternateur. Pour fournir cette énergie électrique, l'alternateur transforme de l'énergie mécanique prélevée sur le moteur par la courroie d'alternateur. L'alternateur impose ainsi un couple résistif, proportionnel au courant généré, qui limite la puissance disponible pour les roues et augmente la consommation du véhicule. Currently, the electrical energy used for powering an electrical component, whether it is for example a fan motor and / or pumps and / or any type of electric actuator, is provided by an alternator. To provide this electrical energy, the alternator transforms mechanical energy taken from the engine by the alternator belt. The alternator thus imposes a resistive torque, proportional to the current generated, which limits the available power for the wheels and increases the consumption of the vehicle.
Par ailleurs, il a déjà été proposé des dispositifs thermo électriques utilisant des éléments, dits thermo électriques, permettant de générer un courant électrique en présence d'un gradient de température entre deux de leurs faces opposées selon le phénomène connu sous le nom d'effet Seebeck. La présente demande a pour objet de proposer une utilisation avantageuse de l'énergie électrique produite par de tels dispositifs thermo électriques dans le cadre de la problématique soulevée plus haut.  Moreover, it has already been proposed thermoelectric devices using so-called electric thermo elements, for generating an electric current in the presence of a temperature gradient between two of their opposite faces according to the phenomenon known as the effect Seebeck. The present application aims to propose an advantageous use of the electrical energy produced by such thermoelectric devices in the context of the problem raised above.
L'invention concerne ainsi un ensemble d'un module d'échange de chaleur et d'au moins un organe électrique, ledit module d'échange de chaleur comprenant au moins un dispositif thermo électrique configuré pour fournir un courant électrique à partir d'un gradient de température entre deux fluides échangeant de la chaleur entre eux dans ledit module, ledit dispositif thermo électrique alimentant ledit organe électrique.  The invention thus relates to an assembly of a heat exchange module and at least one electrical member, said heat exchange module comprising at least one thermoelectric device configured to supply an electric current from a temperature gradient between two fluids exchanging heat with each other in said module, said thermoelectric device supplying said electric member.
On se sert de la sorte du module d'échange de chaleur pour à la fois alimenter au moins un organe électrique et pour assurer la fonction de base du module, à savoir l'échange de chaleur. Ainsi, chaque organe électrique est un consommateur d'énergie électrique alimenté de manière autonome par ledit ensemble.  In this way, the heat exchange module is used to supply at least one electrical element and to provide the basic function of the module, namely heat exchange. Thus, each electrical member is a consumer of electrical energy autonomously powered by said assembly.
De préférence, ledit organe électrique est au moins une machine électrique servant à entraîner les fluides passant à travers ledit module. Le module d'échange de chaleur est ainsi apte à alimenter tout ou partie des machines électriques à l'aide du ou des dispositifs thermo électriques intégrés audit ensemble formé d'un module d'échange de chaleur et d'au moins un organe électrique. Le refroidissement des fluides s'effectue ainsi de façon plus autonome. On a en outre constaté une certaine proximité entre la quantité de courant mis à disposition par le ou les dispositifs thermo électriques employés, compte-tenu des gradients de températures disponibles, et les besoins des organes servant à entraîner les fluides en jeu. Selon différents modes de réalisation qui pourront être pris ensemble ou séparément : Preferably, said electrical member is at least one electrical machine for driving fluids passing through said module. The heat exchange module is thus able to supply all or part of the electrical machines using the thermoelectric device or devices integrated in said assembly formed of a heat exchange module and at least one electrical member. The cooling of the fluids is thus performed more autonomously. There has also been a certain proximity between the amount of current made available by the thermoelectric device (s) employed, taking into account the available temperature gradients, and the needs of the organs used to drive the fluids involved. According to different embodiments that can be taken together or separately:
- ledit module d'échange de chaleur comprend un premier échangeur de chaleur, un second échangeur de chaleur et/ou un troisième échangeur de chaleur,  said heat exchange module comprises a first heat exchanger, a second heat exchanger and / or a third heat exchanger,

- ledit second échangeur de chaleur, dit radiateur basse température, est autre radiateur de refroidissement d'un liquide caloporteur, servant à refroidir d'autres fluides,  said second heat exchanger, called a low-temperature radiator, is another coolant for cooling a heat-transfer fluid, for cooling other fluids,
- ledit troisième échangeur est un condenseur d'une boucle de climatisation,  said third exchanger is a condenser of an air conditioning loop,
- ledit ensemble comprend en outre au moins un groupe moto- ventilateur entraîné par la ou l'une desdites machines électriques, ledit groupe forçant une circulation du flux d'air à travers ledit module d'échange de chaleur,  said assembly furthermore comprises at least one motor-fan unit driven by the one or one of said electrical machines, said group forcing a circulation of the air flow through said heat exchange module,
- ledit groupe moto-ventilateur force ledit flux d'air à travers lesdits échangeurs,  said fan motor unit forces said flow of air through said exchangers,
- ledit ensemble comprend en outre une pompe entraînée par la ou l'une desdites machines électriques, ladite pompe forçant une circulation de liquide caloporteur à travers ledit module d'échange de chaleur, - ladite pompe entraine ledit liquide caloporteur à travers ledit second échangeur. said assembly furthermore comprises a pump driven by the one or one of said electrical machines, said pump forcing a circulation of heat transfer liquid through said heat exchange module, said pump causes said heat transfer fluid to pass through said second exchanger.
Selon un aspect de l'invention, ledit dispositif thermo électrique comprend des éléments, dits thermo électriques, permettant de générer un courant électrique en présence d'un gradient de température, et ledit premier échangeur, ledit second échangeur et/ou ledit troisième échangeur comprennent chacun un faisceau d'échange de chaleur, le faisceau du ou desdits échangeur de chaleur comprenant :  According to one aspect of the invention, said thermoelectric device comprises elements, said electrical thermo, for generating an electric current in the presence of a temperature gradient, and said first exchanger, said second exchanger and / or said third exchanger comprise each a heat exchange bundle, the bundle of said heat exchanger (s) comprising:
- une première zone configurée pour permettre un échange de chaleur entre un premier, dit chaud, desdits deux fluides échangeant de la chaleur dans le faisceau et un second, dit froid, desdits deux fluides, et  a first zone configured to allow a heat exchange between a first, said hot, of said two fluids exchanging heat in the beam and a second, said cold, of said two fluids, and

Il s'agit, par exemple, d'éléments de forme sensiblement parallélépipédiques générant un courant électrique, selon l'effet Seebeck, lorsqu'ils sont soumis audit gradient entre deux de leurs faces opposées, dites faces de contact. De tels éléments permettent la création d'un courant électrique dans une charge connectée entre lesdites faces de contact.

Par souci de simplification, seule l'intégration du dispositif thermo électrique 24 du premier échangeur est traitée dans la suite et le fluide chaud en cause est donc le liquide caloporteur F1 évoqué plus haut.  For the sake of simplification, only the integration of the thermoelectric device 24 of the first exchanger is treated in the following and the hot fluid in question is the heat transfer liquid F1 mentioned above.
Ladite première zone 102 est prévue, par exemple, en aval de la seconde zone 104 selon le sens de circulation du fluide chaud F1 .  Said first zone 102 is provided, for example, downstream of the second zone 104 in the direction of circulation of the hot fluid F1.

Ladite deuxième partie 104 du faisceau comprend en outre des seconds intercalaires 1 12 en relation d'échange thermique avec le second fluide F4. Lesdits éléments thermo électriques 100 sont positionnés entre lesdits premiers 1 1 1 et seconds 1 12 intercalaires. Selon ce mode de réalisation, ce sont donc les premiers 1 1 1 et seconds 1 12 intercalaires qui remplissent la fonction d'établissement du contact thermique avec les éléments thermo électriques 100. Said beam 101 here comprises round and / or oval tubes 1 and first spacers January 1 in heat exchange relationship with said round tubes and / or ovals 1 10.

Said second portion 104 of the bundle further comprises second tabs 1 12 in heat exchange relation with the second fluid F4. Said thermoelectric elements 100 are positioned between said first 1 1 1 and second 1 12 interleavers. According to this embodiment, it is therefore the first 1 1 1 and second 1 12 spacers that fulfill the function of establishing the thermal contact with the electric thermo elements 100.
Les premiers 1 1 1 et seconds 1 12 intercalaires sont, par exemple, en forme d'ailettes planes.

Lesdits premiers intercalaires 1 1 1 sont maintenues sur les tubes 1 10 et/ou les tubes 1 10 sont maintenus dans les boîtes 150, par exemple, par sertissage.

They open at each end into collector boxes 150 of the exchanger, through passage orifices provided thereon, for example at collector plates 152 of said boxes 150. Inserts 1 1 1, 1 12 are perpendicular to the tubes and traversed by them. Said first spacers January 1 are maintained on the tubes 1 10 and / or the tubes 1 10 are maintained in the boxes 150, for example, by crimping. A seal, non-visible, is used to seal between the collector plates 152 and the tubes 1 10 at each of their through holes. The second spacers January 12 are configured, for example, to make a heat shield protecting the first spacers January 1 of a flow of the second fluid.
Les seconds intercalaires 1 12 ont, notamment, une forme en L, un flanc 120 du L venant coiffer l'un au moins desdits premiers intercalaires 1 1 1 , ledit flanc 120 s'étendant parallèlement aux tubes 1 10.  The second spacers January 12 have, in particular, an L-shaped, a flank 120 of the L coming to cap at least one of said first spacers January 1, said flank 120 extending parallel to the tubes 1 10.
Les éléments thermo électriques 100 sont situés entre l'autre flanc 121 du L, ledit autre flanc s'étendant transversalement aux tubes 1 10, et la face du premier intercalaire 1 1 1 , prévue en vis-à-vis.  The thermoelectric elements 100 are located between the other sidewall 121 of the L, said other side extending transversely to the tubes 1 10, and the face of the first spacer 1 1 1, provided vis-a-vis.
La face opposée du premier intercalaire 1 1 1 peut également être en contact contre d'autres éléments thermo électriques 100.  The opposite face of the first spacer 1 1 1 may also be in contact with other thermoelectric elements 100.

Les seconds intercalaires 1 12 sont munis d'orifices permettant également le passage des tubes 1 10 mais, cette fois, sans contact pour éviter tout pont thermique entre le premier fluide F1 et le second fluide F4. Ladite seconde zone 104 pourra encore comprendre des entretoises 160 de maintient des seconds intercalaires 1 12.

Said second zone 104 may further comprise spacers 160 holding second spacers 1 12. Said spacers 160 pass without contact through orifices 162 of said first spacers January 1 and with contact through orifices of said second spacers January 12.
