Abstract

L'invention concerne un dispositif pour le refroidissement de gaz, dans lequel le gaz peut être guidé par des canaux (5) d'un dispositif de refroidissement (1) dans lequel, au voisinage desdits canaux (5), se trouvent également des canaux (10) destinés à un milieu de refroidissement en circulation. Le dispositif de refroidissement (1) présente, centralement à l'intérieur, les canaux (10) destinés au milieu de refroidissement et, radialement à l'extérieur, les canaux (5) destinés au gaz à refroidir.

Claims (6)

  1. Dispositif de refroidissement de gaz, dans lequel le gaz chemine dans des canaux (5) d'un dispositif refroidisseur (1) qui comporte, au voisinage des canaux (5) d'autres canaux (10) pour le passage d'un fluide de refroidissement,
    caractérisé en ce que
    le dispositif refroidisseur (1) avec ses canaux (5, 10) est composé de parties coulées sous pression, un premier couvercle (4) comportant une entrée annulaire pour le gaz à refroidir, tandis qu'un second couvercle (7) présente une sortie en forme d'entonnoir pour le gaz à refroidir, une pièce intermédiaire (6) étant prévue avec des canaux (5, 10), de sorte que les canaux (5, 10) permettent la traversée du dispositif de refroidissement par les gaz, et ainsi par le fluide de refroidissement selon des sens alternés.

    le dispositif refroidisseur (1) comprend radialement vers l'intérieur les canaux (10) du fluide de refroidissement et radialement vers l'extérieur les canaux (5) du gaz à refroidir.
  3. Dispositif selon les revendications 1 ou 2,
    caractérisé en ce que
    des nervures de refroidissement (12) sont prévues sur l'extérieur du dispositif refroidisseur (1).
  4. Dispositif selon les revendications 1 ou 2,
    caractérisé en ce que
    le gaz, prélevé par dérivation sur les gaz d'échappement d'un moteur à combustion interne est ramené dans la ligne d'admission du moteur et le fluide de refroidissement est le liquide de circuit de refroidissement du moteur.
  5. Dispositif selon l'une des revendications précédentes,
    caractérisé en ce que
    sur la pièce intermédiaire (6) est monté extérieurement un morceau d'un profilé d'aluminium extrudé.
