ENGINE COOLING SYSTEM AND COOLING FAN MODULE

摘要

An engine cooling system incorporates a cooling fan module having a motor and a fan driven by the motor. The motor has a motor housing and two end caps disposed at respective ends of the motor housing. Each of the end caps has at least one axial hole to allow air to flow through the motor to dissipate heat from inside the motor. The motor also has a dust screen disposed inside the motor and adjacent each of the axial holes for preventing external particles entering the motor through the axial hole. Each dust screen has a plurality of apertures to allow air to flow through the motor but prevents dust particles entering the motor.
