Description
TURBOCOMPRESSEUR A CIRCUIT DE REFROIDISSEMENT INTEGRE. L'invention concerne le domaine de la suralimentation en air des moteurs à 5 combustion interne équipés d'un turbocompresseur. Elle concerne en particulier le refroidissement de tels turbocompresseurs. TURBOCHARGER WITH INTEGRATED COOLING CIRCUIT. The invention relates to the field of air supercharging of internal combustion engines equipped with a turbocharger. It relates in particular to the cooling of such turbochargers.
Les turbocompresseurs équipant les moteurs à combustion interne comportent un turbo destiné à récupérer la puissance des gaz 10 d'échappement en provenance d'un moteur à combustion interne, et un compresseur lié au turbo destiné à comprimer les gaz frais aspirés par un moteur à combustion interne. The turbochargers fitted to internal combustion engines comprise a turbo for recovering the power of the exhaust gases from an internal combustion engine, and a compressor linked to the turbo for compressing the fresh gases sucked in by a combustion engine. internal.
La partie turbo du turbocompresseur est parcourue par les gaz 15 d'échappement provenant du moteur. Ces gaz d'échappement issus de la combustion sont à une température très élevée et élèvent la température du turbo. En outre le turbo est lié en rotation à un compresseur. La rotation à haute vitesse du turbo et du compresseur provoque également une élévation de la température de l'ensemble turbocompresseur. 20 Le turbocompresseur comporte pour son refroidissement, un carter central à refroidissement par liquide. Ce carter comporte des canaux dans lesquels circule un liquide de refroidissement qui prélève des calories lors de sa circulation. Afin d'amener ce liquide de refroidissement jusqu'au carter central, des conduits d'alimentation en liquide de refroidissement sont prévus. 25 -2 On a représenté à la figure 1 un turbocompresseur 5 équipé de conduits d'alimentation en liquide de refroidissement 7. Comme on peut le voir sur cette figure, ces conduits 7 contournent le carter compresseur pour se raccorder à l'entrée des canaux du carter central. Ces conduits 7 sont donc consommateurs d'espace dans le compartiment moteur d'un véhicule automobile ce qui est un problème. The turbo portion of the turbocharger is traversed by exhaust gases from the engine. These exhaust gases from the combustion are at a very high temperature and raise the temperature of the turbo. In addition the turbo is linked in rotation to a compressor. The high speed rotation of the turbo and the compressor also causes a rise in the temperature of the turbocharger assembly. The turbocharger comprises for its cooling, a central casing liquid-cooled. This housing has channels in which circulates a coolant that takes calories during its circulation. In order to bring this coolant to the central casing, coolant supply ducts are provided. FIG. 1 shows a turbocharger 5 equipped with coolant supply ducts 7. As can be seen in this figure, these ducts 7 bypass the compressor housing to connect to the inlet of the channels of the central casing. These ducts 7 are therefore consuming space in the engine compartment of a motor vehicle which is a problem.
En outre lors du fonctionnement du moteur ou du déplacement du véhicule, 10 les mouvements de ces conduits sont générateurs de vibrations. Ces vibrations peuvent entraîner la fragilisation de ces conduits de refroidissement ou d'autres composants du moteur. In addition, during the operation of the motor or the movement of the vehicle, the movements of these ducts generate vibrations. These vibrations can lead to embrittlement of these cooling ducts or other engine components.
Pour résoudre ce problème de vibration, le carter compresseur comporte un 15 bossage supplémentaire 9. Une patte 11 de maintien reliant les conduits 7 au bossage 9 est également prévue. To solve this vibration problem, the compressor housing has an additional boss 9. A holding lug 11 connecting the ducts 7 to the boss 9 is also provided.
Cette solution demande donc l'ajout d'un bossage et d'une patte supplémentaire de maintien qui sont susceptibles de casser durant la vie du 20 turbocompresseur. This solution therefore requires the addition of a boss and an additional support tab that are likely to break during the life of the turbocharger.
Un but de la présente invention est de résoudre les problèmes ci-dessus évoqués en proposant un turbocompresseur comportant un dispositif de refroidissement consommant un espace faible et ne requérant pas de patte 25 de fixation supplémentaire pour son maintien au turbocompresseur. An object of the present invention is to solve the problems mentioned above by proposing a turbocharger comprising a cooling device that consumes a small space and does not require an additional fixing lug to maintain it at the turbocharger.
Un autre but de l'invention est de diminuer la longueur des conduits de refroidissement de l'art antérieur.5 - 3 Another object of the invention is to reduce the length of the cooling ducts of the prior art.

On a représenté aux figures 2 à 4 un turbocompresseur 13 selon l'invention. Le turbocompresseur 13 comporte un carter turbo 15 et un carter compresseur 17. Le carter turbo 13 comporte une bride 19 pour sa fixation à un conduit d'échappement (non représenté sur la figure) des gaz produits par un moteur à combustion interne. Le carter compresseur 17 comporte une paroi radiale externe 17a et une paroi axiale externe 17b et un conduit 30 d'amenée d'air frais à comprimer. Le carter compresseur 17 comporte un conduit 12 d'amenée d'air frais comprimé vers l'admission d'un moteur à combustion interne. FIGS. 2 to 4 show a turbocharger 13 according to the invention. The turbocharger 13 comprises a turbo casing 15 and a compressor casing 17. The turbo casing 13 comprises a flange 19 for attachment to an exhaust duct (not shown in the figure) of the gases produced by an internal combustion engine. The compressor housing 17 comprises an outer radial wall 17a and an outer axial wall 17b and a duct 30 for supplying fresh air to be compressed. The compressor housing 17 comprises a duct 12 for supplying fresh compressed air to the intake of an internal combustion engine.
Comme on peut le voir sur les figures 2 à 4, le carter compresseur 17 comporte deux conduits de refroidissement 21a et 21b. Plus précisément, ces conduits de refroidissement 21a et 21b sont intégrés au carter compresseur 17. Les conduits 21a et 21b de refroidissement sont liés à la paroi externe du carter compresseur 17. Les conduits 21a et 21 b s'étendent chacun sur la paroi radiale externe 17a du carter compresseur 17 et se prolongent sur la paroi axiale externe 17b du carter compresseur 17. -5 Dans le mode de réalisation représentée aux figures 2 et 3, l'un des conduits 21a ou 21b est destiné à acheminer le liquide de refroidissement frais en provenance du circuit de refroidissement du moteur vers le carter central 25 du turbocompresseur, tandis que l'autre conduit 21a ou 21b est destiné à évacuer le liquide chargé en calorie vers le système de refroidissement du moteur afin que ce liquide soit refroidi. Les conduits 21a et 21b peuvent être réalisés venue de matière avec le carter 17 du compresseur 13. La paroi externe du carter compresseur 17 peut constituer une paroi interne pour chaque conduit 21 a ou 21 b. Ceci signifie que lors du fonctionnement du moteur, le liquide de refroidissement sera en contact avec la paroi externe du carter compresseur. 15 Chacun des conduits 21a ou 21b comporte à son extrémité libre un embout 23a,23b de type collerette ou à renflement pour son raccord avec le circuit de refroidissement du moteur. Ces embouts permettent la connexion rapide des conduits 21 a et 21 b avec des tuyaux souples provenant d'autres éléments du 20 moteur. As can be seen in Figures 2 to 4, the compressor housing 17 has two cooling ducts 21a and 21b. More specifically, these cooling ducts 21a and 21b are integrated in the compressor casing 17. The cooling ducts 21a and 21b are connected to the outer wall of the compressor casing 17. The ducts 21a and 21b each extend on the outer radial wall 17a of the compressor casing 17 and extend on the outer axial wall 17b of the compressor casing 17. -5 In the embodiment shown in Figures 2 and 3, one of the ducts 21a or 21b is intended to convey the fresh coolant from the engine cooling circuit to the central casing 25 of the turbocharger, while the other conduit 21a or 21b is intended to evacuate the liquid loaded calorie to the cooling system of the engine so that the liquid is cooled. The ducts 21a and 21b can be made integrally with the casing 17 of the compressor 13. The outer wall of the compressor casing 17 may constitute an inner wall for each duct 21a or 21b. This means that during operation of the engine, the coolant will be in contact with the outer wall of the compressor housing. Each of the ducts 21a or 21b comprises at its free end a flange-type or bulge-shaped end piece 23a, 23b for its connection with the engine cooling circuit. These tips allow the rapid connection of the ducts 21a and 21b with flexible hoses from other engine components.
Comme on peut le voir sur la figure 3, chaque conduit 21 a,21 b a une forme en V lui permettant de contourner la le conduit 30 d'amenée d'air frais à comprimer.As can be seen in FIG. 3, each duct 21 a, 21 b has a V-shape enabling it to bypass the duct 30 for supplying fresh air to be compressed.
25 On se reporte à présent à la figure 4. Le carter central 25 du turbocompresseur 13 définit des orifices 25a et 25b destinés à coopérer avec les conduits de refroidissement 21a et 21 b. A cet effet, chaque conduit 21a et 21 b comporte à son extrémité destinée à coopérer avec les orifices 25a et 30 25b du carter central 25 un conduit de raccordement 27a ou 27b. Chaque10 -6 conduit 27a ou 27b peut être réalisé en inox. Les conduits de raccordement 25a ou 25b peuvent être mis en place lors de l'assemblage du turbocompresseur 13 ou peuvent être réalisés en fonderie.5 Referring now to FIG. 4, the central casing 25 of the turbocharger 13 defines ports 25a and 25b for cooperating with the cooling ducts 21a and 21b. For this purpose, each duct 21a and 21b has at its end intended to cooperate with the orifices 25a and 25b of the central casing 25 a connecting duct 27a or 27b. Each 10 -6 conduit 27a or 27b can be made of stainless steel. The connecting ducts 25a or 25b can be put in place during the assembly of the turbocharger 13 or can be made in the foundry.5
