Cooling device for an internal combustion engine and method for controlling such a cooling device

摘要: A device and method for cooling an internal combustion engine is disclosed in which a simple control circuit constructed of relatively inexpensive components enables the rotational speed electric motor employed to be controlled adaptation various temperature levels circuit. The includes power semiconductor used drive certain ranges associated with predetermined levels. also incorporates bypass that permits electrical driven particular without use semiconductor. Thus, can at one hundred percent its capacity by eliminating voltage drop
