Abstract

La présente invention concerne un système d'eau de refroidissement pour une culasse d'un moteur. Une cavité d'eau de refroidissement est formée dans une culasse. La cavité d'eau de refroidissement de la culasse est divisée en une cavité d'eau de couche supérieure et en une cavité d'eau de couche inférieure au moyen d'une cloison de séparation médiane. De l'eau de refroidissement entre dans la cavité d'eau de couche supérieure à travers un trou d'entrée d'eau. Un trou de communication est disposé entre la cavité d'eau de couche supérieure et la cavité d'eau de couche inférieure. De l'eau de refroidissement de couche inférieure entre dans la cavité d'eau de couche supérieure à travers le trou de communication. Dans ledit système d'eau de refroidissement destiné à une culasse d'un moteur, la partie inférieure de la culasse peut être refroidie en refroidissant dans la plus grande mesure possible un liquide dans la culasse. Un trou de remplissage d'eau de la culasse est disposé sous un canal de sortie d'air, et un trou de communication entre les deux couches de chemises d'eau est disposé à côté d'un canal d'entrée d'air, de sorte que le liquide de refroidissement entre dans la culasse à partir d'un côté inférieur du canal de sortie d'air, et que, dans la culasse, le liquide de refroidissement s'écoule à travers une région située entre le canal de sortie d'air et la culasse, une région située entre les canaux de sortie d'air et une région située entre le canal de sortie d'air et le canal d'entrée d'air, et entre ensuite dans la chemise d'eau de couche supérieure de la culasse à partir d'un côté d'entrée d'air, refroidissant ainsi complètement une région à haute température autour du canal de sortie d'air.
