Abstract
Description
La présente invention relève du domaine de la climatisation d'un véhicule et, plus particulièrement de la modification de la température de l'air frais qui est normalement admis dans l'habitacle. Cette possibilité de modification de température est particulièrement intéressante
pour le refroidissement de l'air à admettre dans le dit habitacle.The present invention relates to the field of air conditioning of a vehicle and, more particularly to the modification of the temperature of the fresh air which is normally admitted into the passenger compartment. This possibility of temperature modification is particularly interesting
for cooling the air to be admitted into the said passenger compartment.
Parmi les dispositifs connus, certains utilisent un fluide frigorigène, d'autres un compresseur, c1est- a-dire des moyens complexes, onéreux et susceptibles de pannes diverses. Among the known devices, some use a refrigerant, others a compressor, that is to say complex means, expensive and susceptible to various breakdowns.
Pour remédier à ces inconvénients, l'inventeur a mis au point un dispositif extrémement simple et peu onéreux, sans aucune pièce mécanique en mouvement, et/ou sans fluide spécial, et d'une application plus générale que les dispositifs connus. To overcome these drawbacks, the inventor has developed an extremely simple and inexpensive device, without any moving mechanical part, and / or without special fluid, and of a more general application than known devices.
Le dispositif selon l'invention comporte d'une part un tube tourbillon connu en lui-meme, et au moins une conduite de sortie d'air refroidi relié à au moins un diffuseur ouvrant dans, ou sur la partie à refroidir, dispositif caractérisé en ce qu'il comprend deux venturis, que chaque extrémité du tube tourbillon est reliée a un venturi avec qui elle communique au niveau de son col, que chaque venturi est alimenté en air grâce à un ou plusieurs capteurs dirigés vers l'avant,. qu'une tuyère conduit de l'air extérieur capté à l'avant, aux fentes du tube tourbillon, de telle sorte que le véhicule se déplaçant à une vitesse suffisante, l'air qui s'est engouffré dans les venturis provoque une dépression à l'intérieur du tube, tandis que l'air provenant de la tuyère se trouve projeté à grande vitesse dans le tube à travers les fentes d'admission disposées de façon à créer un tourbillon intérieur au tube. Du fait de la vitesse, l'air situé près de la paroi du tube se comprime et augmente de température, tandis que l'air situé dans la zone axiale se refroidit, l'écoulement étant adiabatique. L'air refroidi est aspiré par le courant d'air du venturi à l'extrémité froide du dit tube. De là, une canalisation classique conduit cet air refroidi aux diffuseurs dans l'habitacle, ou à proximité de tout autre élément à refroidir. Une canalisation semblable peut éventuellement être utilisée pour l'air chauffé. The device according to the invention comprises, on the one hand, a vortex tube known in itself, and at least one cooled air outlet pipe connected to at least one diffuser opening in, or on the part to be cooled, device characterized in what it includes two venturis, that each end of the vortex tube is connected to a venturi with which it communicates at the level of its neck, that each venturi is supplied with air thanks to one or more sensors directed towards the front. that a nozzle conducts outside air collected at the front, to the slots of the whirlpool tube, so that the vehicle moving at a sufficient speed, the air which has rushed into the venturis causes a vacuum at inside the tube, while the air coming from the nozzle is projected at high speed into the tube through the intake slots arranged so as to create a vortex inside the tube. Due to the speed, the air located near the wall of the tube compresses and increases in temperature, while the air located in the axial zone cools, the flow being adiabatic. The cooled air is sucked in by the air stream from the venturi at the cold end of said tube. From there, a conventional pipe leads this cooled air to the diffusers in the passenger compartment, or near any other element to be cooled. A similar duct can optionally be used for heated air.
Toutefois, si l'invention est appliquée seulement pour refroidir l'habitacle, il n'est évidemment pas nécessaire de monter la canalisation d'air chaud.However, if the invention is applied only to cool the passenger compartment, it is obviously not necessary to mount the hot air duct.
Pour mieux faire comprendre l'invention il est donné ci-après un schéma de réalisation. To make the invention easier to understand, an embodiment is given below.
Le tube tourbillon 1 comporte des fentes 2 dont la section débouche tangentiellement à l'intérieur du tube 1 pour l'admission de l'air et l'obliger à tourner, une extrémité 3 adaptée pour l'écoulement de l'air chauffé et une extrémité 4 adaptée pour l'écoulement de 1 'air refroidi par un petit tube axial 9. The vortex tube 1 has slots 2, the cross section of which opens tangentially inside the tube 1 for admitting air and forcing it to rotate, one end 3 adapted for the flow of heated air and one end 4 adapted for the flow of air cooled by a small axial tube 9.
Un premier venturi 5 est monté à l'extrémité 3, avec une amenée d'air 6 et une sortie 7, l'air circulant suivant les fleches F1. Le col du venturi 5 communique avec l'intérieur du tube 1 par une fente circulaire (non référencée sur le schéma). Un deuxième venturi 8 a son col monté à l'extrémité du canal axial 9, avec une amenée d'air 10 et une sortie 11, l'air circulant suivant les flèches F2. A first venturi 5 is mounted at the end 3, with an air intake 6 and an outlet 7, the air flowing along the arrows F1. The neck of the venturi 5 communicates with the interior of the tube 1 by a circular slot (not referenced in the diagram). A second venturi 8 has its neck mounted at the end of the axial channel 9, with an air intake 10 and an outlet 11, the air circulating according to the arrows F2.
Une tuyère 12, faisant suite à une amenée d'air 13 venant de l'avant, dirige l'air sur les fentes 2 suivant la flèche f. Avantageusement la tuyère 12 est convergente vers les fentes 2 d'admission d'air dans le tube tourbillon 1. Cette tuyère 12 arrive tangentiellement dans la chambre 14 de distribution d'air entourant les fentes 2. Cette chambre 14 est constituée par un cylindre fermé à ses bouts par une couronne le reliant au tube 1 de façon étanche. A nozzle 12, following an air supply 13 coming from the front, directs the air to the slots 2 along the arrow f. Advantageously, the nozzle 12 is convergent towards the slots 2 for admitting air into the vortex tube 1. This nozzle 12 arrives tangentially in the air distribution chamber 14 surrounding the slots 2. This chamber 14 consists of a closed cylinder at its ends by a crown connecting it to the tube 1 in a sealed manner.
Le tube tourbillon 1 peut être monté dans n'importe quelle position dans la voiture, sans que cela modifie son fonctionnement. The whirlpool tube 1 can be mounted in any position in the car, without modifying its operation.
Le dispositif est particulièrement prévu pour refrodir l'habitacle d'un véhicule, et dans ce cas, se trouve fixé sous le capot. Toutefois le dit dispositif peut être prévu pour refroidir n'importe quelle autre partie ou élément de véhicule, par exemple les disques des freins, et dans ce cas, un dispositif est fixé à proximité de chaque roue. The device is particularly designed to cool the passenger compartment of a vehicle, and in this case, is fixed under the hood. However, the said device can be provided for cooling any other part or element of the vehicle, for example the brake discs, and in this case, a device is fixed near each wheel.
Chaque dispositif étant en place, lorsque le véhicule avance à une vitesse suffisante, il se produit des courants d'air F1 et F2 dans les venturis 5 et 8, qui engendrent des dépressions dans le tube tourbillon 1. Pendant ce temps l'air f projeté à grande vitesse dans le tube 1 tourbillonne, se comprime et augmente de température en zône périphérique, tandis que l'air situé dans la zône aixiale se refroidit. Lorsque le dispositif est utilisé pour refroidir un habitacle, l'air refroidi est aspiré par le venturi 8 et conduit dans le dit habitacle tandis que l'air chaud aspiré par le venturi 5 est évacué sans utilisation. Each device being in place, when the vehicle advances at a sufficient speed, air currents F1 and F2 are produced in the venturis 5 and 8, which generate depressions in the vortex tube 1. During this time the air f projected at high speed into the tube 1 swirls, compresses and increases in temperature in the peripheral zone, while the air located in the aixial zone cools. When the device is used to cool a passenger compartment, the cooled air is sucked in by the venturi 8 and leads into said cabin while the hot air sucked in by the venturi 5 is discharged without use.
Ce système ne fonctionne que lorsque le véhciule a une vitesses suffisante. Comme il ne nécessite aucun moteur il peut être monté également sur n'importe quel véhicule sans moteur, notamment sur des remorques. This system only works when the vehicle has sufficient speed. As it does not require any engine, it can also be mounted on any vehicle without an engine, in particular on trailers.
