Motor vehicle cooling device, has protection component e.g. thermal relay/fuse, placed in control and/or command circuit and breaking circuit when temperature of component exceeds preset threshold to protect electric fan

摘要

The device has an electric fan (1) with a terminal (5) connected to a power supply circuit (7) which ensures power supply to the fan based on switching states. A control and/or command circuit (25) controls and/or commands the states of the circuit (7). A protection component (10) e.g. thermal relay/fuse, placed in the circuit (25) breaks the circuit (25) when temperature of the component exceeds a preset threshold to protect the fan.
