STRUCTURE OF FAN SHROUD FOR A MOTOR VEHICLE

摘要

PURPOSE: A fan shroud structure is provided to enhance the cooling efficiency of a fan motor controller by changing the position of the inner device of a fan motor controller to be located in the air flow direction of the fan shroud. CONSTITUTION: For a fan shroud structure, all switching elements in a fan controller(40) are installed on an air path(31). A heat sink, which is attached on one side of the switching element, is exposed to the air path. The cooling is done by the air, which is discharged to the air path by a fan(10).
