Definitions

  • the retarder cooler and the EGR cooler can be arranged in series without need to increase the coolant flow or the diameter of the fluid path compared to a situation where only one of such a cooler were arranged in the coolant fluid path.
  • the combustion engine can be a diesel engine.
  • a very efficient cooling and space saving packaging can be achieved thus enabling the vehicle for larger cooler components required for advanced emission regulations for diesel engines.
  • Fig. 1a shows a first perspective view of an embodiment of a cooling circuit 90 comprising a combustion engine 10, an EGR cooler 40 and a retarder cooler 30.
  • Exhaust gas of the combustion engine 10 can be fed into an exhaust gas recirculation system (EGR system) wherein the EGR cooler 40 cools the exhaust gas discharged from the combustion engine 10.
  • the combustion engine 10 is coupled to a retarder 32 for braking the vehicle, wherein the retarder is cooled by the retarder cooler 30.
  • the invention allows for a very effective packaging by avoiding, for instance, big pipes along the combustion engine 10 as the EGR cooler 40 (Fig. 1a, 1 b) is a part of the return path of the coolant from the combustion engine 10 to the vehicle radiator.

Abstract

L'invention porte sur un circuit de refroidissement (90) pour un véhicule (100), en particulier un véhicule utilitaire, dans lequel le circuit de refroidissement (90) comprend un moteur à combustion (10), un refroidisseur de ralentisseur (30) pour refroidir un ralentisseur (32), un refroidisseur à recirculation des gaz d'échappement (40) pour refroidir un gaz d'échappement du moteur à combustion (10), un refroidisseur de liquide de refroidissement (20) qui est couplé au moteur à combustion (10) pour refroidir le moteur à combustion (10) au moyen d'un liquide de refroidissement. Le refroidisseur de ralentisseur (30) est agencé en permanence en série avec le refroidisseur à recirculation des gaz d'échappement (40) dans un trajet de fluide (60) du liquide de refroidissement formant un circuit de retour pour le liquide de refroidissement du moteur à combustion (10) au refroidisseur de liquide de refroidissement (20).
