Title
(EN) ENGINE COOLING SYSTEM
(FR) SYSTÈME DE REFROIDISSEMENT DE MOTEUR
(JA) エンジン冷却システム
Abstract
(EN)
This engine cooling system minimizes increases in vehicle weight caused by the installation of a Rankine cycle, makes it possible to improve the performance of the Rankine cycle, and is provided with: a Rankine cycle (31) comprising a cooling pump (25), an evaporator (26), an expander (28), and a condenser (29) through which refrigerant (30) circulates in this order; an engine main body (10) in which a turbocharger (6) is arranged in an intake passage (5); and a radiator (3) through which coolant (18) for the engine main body circulates. The engine cooling system is configured so that: a sub-radiator (2) is installed parallel to the radiator (3); compressed air (8) that is compressed by the turbocharger (6) is used as a heating source for the evaporator (26); and the outlet-side coolant (32) of the sub-radiator (2) is used as a cooling source for the condenser (29).

 L'invention concerne un système de refroidissement de moteur, lequel permet de limiter l'augmentation du poids du véhicule due à la présence d'un cycle de Rankine tout en améliorant les performances de ce cycle de Rankine. Plus spécifiquement, ce système de refroidissement de moteur comporte: un cycle de Rankine (31) dans lequel un fluide frigorigène (30) circule successivement dans une pompe (25) à fluide frigorigène, un évaporateur (26), un dispositif d'expansion (28) et un condensateur (29); un corps principal (10) de moteur comportant un turbocompresseur (6) placé sur un passage (5) d'air d'admission; et un radiateur (3) dans lequel circule l'eau de refroidissement (18) pour le corps principal de moteur. Un radiateur auxiliaire (2) est situé parallèlement au radiateur (3). Ce système est conçu de façon que l'air comprimé (8) au moyen du turbocompresseur (6) est utilisé comme source de chaleur de l'évaporateur (26) et que l'eau de refroidissement (32) côté sortie du radiateur auxiliaire (2) est utilisée comme source de refroidissement du condensateur (29).
