Cooling mechanism for electronic device

Abstract

Abstract PURPOSE:To control amount of cold air passing through a vacant slot or individual electronic circuit packages, by providing a guide pin on each electronic circuit package for pushing an L-shaped arm to rotate the same so that air resistance is regulated by a guide vane. CONSTITUTION:When a slot is vacant and no electronic circuit package is inserted therein, a guide vane 1 is turned to the transverse position by tension of a spring 3 to close the passage of cold air. When a package 9 is inserted into the slot, a guide pin 11 pushes a rod 15 of an L-shaped arm 4 to rotate the same and the guide vane 1 is thereby turned to the vertical position to open the passage of cold air. The side edge of a fan type plate 14 engaging the guide vane 1 takes various positions according to rotational angular positions of the L-shaped arm 4. Accordingly, passage condition or amount of cold air can be regulated by changing the position of attaching the guide pin 11.
