Description

La presente invention concerne un dispositif de refroidissement d un ou de plusieurs organes d un véhicule automobile situés dans un méme compartiment que le moteur. ce compartiment entant délimite â l'avant par un radiateur d'un circuit de refroidissement du moteur. et un ventilateur étant disposé entre le radiateur et une ouverture de la face avant du véhicule. de manière a pulser de l'air à travers ce radiateur. The present invention relates to a device for cooling one or more components of a motor vehicle located in the same compartment as the engine. this compartment being delimited at the front by a radiator of an engine cooling circuit. and a fan being arranged between the radiator and an opening in the front face of the vehicle. so as to pulsate air through this radiator.

Le refroidissement de certains organes est particulièrement nécessaire dans de nombreux véhicules modernes car
- le compartiment moteur est soumis à d'importantes fluctuations thermiques dues notamment à la puissance maximale élevée du moteur. aux faibles dimensions de l'ouverture de la face avant du véhicule, et aux bonnes étanchéités autour de cette ouverture.The cooling of certain organs is particularly necessary in many modern vehicles because
- the engine compartment is subject to significant thermal fluctuations due in particular to the high maximum power of the engine. the small dimensions of the opening of the front face of the vehicle, and the good seals around this opening.

pour limiter la résistance aérodynamique a 1' avance- ment du véhicule; et
- lesdits organes sont parfois vulnérables a la chaleur en raison notamment d'un ramollissement et d'un vieillissement prématuré des matériaux plastiques constituant ceux-ci, d'une évaporation d'électrolyte
Si l'organe est un accumulateur électrique et d'une dégradation par dilatation de micro-éléments électroniques Si l'organe destiné notamment a l'allumage du moteur. comporte de tels éléments.to limit aerodynamic resistance to the advancement of the vehicle; and
- Said organs are sometimes vulnerable to heat due in particular to a softening and premature aging of the plastic materials constituting them, an evaporation of electrolyte
If the organ is an electric accumulator and degradation by expansion of electronic micro-elements If the organ intended in particular for the ignition of the engine. contains such elements.

Dans l'état de la technique, ces organes sont refroidis par l'air traversant 1 ouverture de la face avant puis le radiateur. In the state of the art, these members are cooled by air passing through 1 opening of the front face then the radiator.

Ce refroidissement est souvent insuffisant car en traversant le radiateur, 1 air s échauffe et son écoulement est freiné.  This cooling is often insufficient because when passing through the radiator, 1 air heats up and its flow is slowed down.

On connait également d'après le brevet FR. 1 559 865, un dispositif réalisant l'aération d'un accumulateur électrique en prélevant de l'air dans l'habitacle du véhicule et en le dirigeant successivement dans- un boitier enveloppant l'accumulateur puis dans une buse reliant le radiateur au ventilateur, celui-ci étant placé en aval du radiateur et extrayant l'air de la buse vers le compartiment moteur. Cependant, cette solution, relativement coûteuse et encombrante, est inefficace dés que le ventilateur s'arrë- te. We also know from the FR patent. 1,559,865, a device performing the ventilation of an electric accumulator by taking air from the passenger compartment of the vehicle and directing it successively in a casing enveloping the accumulator then in a nozzle connecting the radiator to the fan, this being placed downstream of the radiator and extracting the air from the nozzle towards the engine compartment. However, this relatively expensive and bulky solution is ineffective as soon as the fan stops.

Le but de l'invention est donc de résoudre ces problèmes en réalisant, de façon peu coûteuse. un dispositif de refroidissement desdits organes qui soit efficace quand le moteur et son radiateur sont parti culiérement chauds et quand le ventilateur s'arrete.  The object of the invention is therefore to solve these problems by implementing, inexpensively. a device for cooling said members which is effective when the engine and its radiator are particularly hot and when the fan stops.

A cet effet, 1 invention a pour objet un dispositif de refroidissement, dans un véhicule automobile, d'un ou de plusieurs organes situés dans un compartiment moteur délimité à l'avant par un radiateur d'un circuit de refroidissement du moteur. un ventilateur étant disposé entre le radiateur et une ouverture de la face avant du véhicule, et une buse reliant le ventilateur au radiateur, caractérisé en ce qu'il comporte un conduit dont une extrémité est raccordée à la buse et dont l'autre extrémité est située prés dudit organe. To this end, 1 invention relates to a cooling device, in a motor vehicle, of one or more members located in an engine compartment delimited at the front by a radiator of an engine cooling circuit. a fan being disposed between the radiator and an opening on the front face of the vehicle, and a nozzle connecting the fan to the radiator, characterized in that it comprises a duct, one end of which is connected to the nozzle and the other end of which is located near said organ.

Avantageusement, le conduit est. du côté de l'organe, raccordé à un boitier enveloppant au moins partiellement ce dernier. Advantageously, the conduit is. on the side of the member, connected to a housing at least partially enveloping the latter.

L'invention sera mieux comprise a l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés. sur lesquels
- la Fig.1 représente une vue schématique en coupe d un ensemble de ventilation d'un moteur d'un véhicule automobile équipé d'un dispositif de refroidissement selon l'invention; et
- la Fig.2 représente une vue en perspective de ce meme dispositif de refroidissement.The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the accompanying drawings. on which ones
- Fig.1 shows a schematic sectional view of a ventilation assembly of an engine of a motor vehicle equipped with a cooling device according to the invention; and
- Fig.2 shows a perspective view of the same cooling device.

Ainsi qu'on peut le voir sur la Fiv.1 un circuit de refroidissement d'un moteur de véhicule automobile comporte un radiateur de refroidissement 1 disposé en regard d'une ouverture 2 ménagée dans la face avant du véhicule entre par exemple un capot 3 et un pare-choc 4. De manière connue en soi un groupe moto-ventilateur 5 et une buse 6 de raccordement du ventilateur au radiateur, sont disposés entre 1' ou- verture 2 de la face avant du véhicule et le radiateur: celui-ci délimite. ainsi qu une cloison A
(Fig.2) juxtaposée, la partie antérieure d'un compartiment B contenant le moteur du véhicule.As can be seen in Fiv. 1 a cooling circuit of a motor vehicle engine comprises a cooling radiator 1 disposed opposite an opening 2 formed in the front face of the vehicle, for example between a cover 3 and a bumper 4. In a manner known per se, a motor-fan unit 5 and a nozzle 6 for connecting the fan to the radiator, are arranged between the opening 2 on the front face of the vehicle and the radiator: this delimits. as well as a partition A
(Fig. 2) juxtaposed, the front part of a compartment B containing the vehicle engine.

Le dispositif de refroidissement selon l'in- vention comporte également un conduit 7 dont une ex trémité est raccordée à la buse 6 et dont l'autre extrémité est située près d'un organe 8, tel que notamment un accumulateur électrique, qui est logé dans le compartiment 8 et qu'il y a lieu de refroidir. The cooling device according to the invention also comprises a duct 7, one end of which is connected to the nozzle 6 and the other end of which is located near a member 8, such as in particular an electric accumulator, which is housed in compartment 8 and that it is necessary to cool.

Ce conduit 7 prélève de l'air en amont du radiateur, donc de l'air relativement frais et cet air est pulsé
- soit par le groupe moto-ventilateur 5. ce qui assure une aération maximale de l'organe 8 lorsque le ventilateur tourne donc lorsque la température du moteur dépasse un seuil donné et que le compartiment moteur est particulièrement chaud,
- soit par effet dynamique dû au déplacement du véhicule et à la pression d'air régnant dans la buse du fait de l'importante perte de charge dans l'é coulement d'air à travers le radiateur.This duct 7 takes air upstream of the radiator, therefore relatively fresh air and this air is pulsed
- either by the motor-fan unit 5. which ensures maximum ventilation of the member 8 when the fan therefore rotates when the engine temperature exceeds a given threshold and the engine compartment is particularly hot,
- Or by dynamic effect due to the movement of the vehicle and the air pressure prevailing in the nozzle due to the significant pressure drop in the flow of air through the radiator.

Ainsi qu'on peut le voir plus-clairement sur la Fig.2. le conduit 7 d'aération peut etre relié à la buse 6 par l'intermédiaire d'un organe 9 formant collecteur d'air disposé sur une partie périphérique de la buse 6 et son extrémité disposée à proximité de l'organe 8 peut comporter une partie évasée 10. As can be seen more clearly in Fig. 2. the ventilation duct 7 can be connected to the nozzle 6 by means of a member 9 forming an air collector disposed on a peripheral part of the nozzle 6 and its end disposed near the member 8 may include a flared part 10.

Cependant, selon un autre mode de réalisa-tion, l'extrémité située près de l'organe 8 peut etre raccordée à un boitier enveloppant au moins partinllement ce dernier de manière à assurer une circulation relativement uniforme de l'air. However, according to another embodiment, the end located near the member 8 can be connected to a casing at least partially enveloping the latter so as to ensure a relatively uniform circulation of the air.

Il va de soi également que le conduit peut comporter plusieurs extrémités disposées à proximité de plusieurs organes situés dans le compartiment moteur du véhicule de maniere à assurer leur ventilation, un de ces organes pouvant étre notamment un échangeur pour la suralimentation du moteur du véhicule, le refroidissement de cet échangeur étant satisfaisant en particulier a faible vitesse d'avancement du véhicule grâce à la ventilation par air pulsé du dispositif.  It also goes without saying that the duct may have several ends arranged near several members located in the engine compartment of the vehicle so as to ensure their ventilation, one of these members possibly being in particular an exchanger for the supercharging of the vehicle engine, the cooling of this exchanger being satisfactory in particular at low speed of advance of the vehicle thanks to the ventilation by forced air of the device.
