The housing includes a key portion at a front end thereof, and a supporting portion at a rear end thereof. The supporting portion defines a plurality of ventilation holes and through holes. The fan includes an inlet and an outlet perpendicular to the inlet. The fan draws ambient air through the ventilation holes and expels air through the through holes to ventilate a surface of the housing. |
