Umwälzanlage für Kühlmittel in einem Fahrzeug

摘要

An object of the invention is to provide a circulation apparatus for coolant in a vehicle, which realizes miniaturization and weight reduction of equipment. A feature of the invention is that with a circulation apparatus for coolant in a vehicle for cooling apparatus to be cooled by a coolant, a coolant circulation system is separated into a coolant circulation system having a first radiator 8 for an engine cooling, and a coolant circulation system having a second radiator 9 for electric motor and engine equipment cooling. With the second radiator 9, various apparatus to be cooled, namely the drive motor and engine equipment are cooled, and there is provided circulation quantity control devices 53, 54, 57 for controlling the quantity of coolant circulated to the various apparatus to be cooled.
