Title (EN) COOLING SYSTEM FOR A VEHICLE WITH AN INTERNAL COMBUSTION ENGINE
(FR) SYSTEME DE REFROIDISSEMENT D'UN VEHICULE A MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) A system for cooling and/or heating an internal combustion engine as well as heating a passenger compartment when required. In the system, the alternator (14) in the engine cooling circuit (12) powers thermoelectric heating components (16) in the cooling circuit (16) and/or the passenger compartment (22). The compartments are connected to the battery voltage (VB) via switches that are opened and closed by a device (26) depending on measured variables such as the external temperature (Tx), the coolant temperature (Te), the passenger compartment temperature (Th), etc. Said system may be used in internal combustion engines having an alternator cooled by the engine cooling circuit.
(FR) L'invention concerne un système pour refroidir et/ou chauffer un moteur à combustion interne tout en permettant le chauffage de l'habitacle en cas de besoin. L'invention réside dans le fait que l'alternateur (14) disposé dans le circuit de refroidissement (12) du moteur, alimente des composants thermoélectriques de chauffage (16) dans le circuit de refroidissement (16) et/ou dans l'habitacle (22); ces composants sont connectés à la tension de batterie VB par l'intermédiaire d'interrupteurs dont l'ouverture et la fermeture sont commandées par un dispositif (26) en fonction de variables relevées telles que la température extérieure (Tx), celle du liquide de refroidissement (Te), celle de l'habitacle (Th),... L'invention est applicable aux moteurs à combustion interne avec alternateur refroidi par le circuit de refroidissement du moteur.
