Abstract
The present invention is to provide a wind guide device for a cooling fan mounted on a CPU of a computer comprising a first shroud and a second shroud. A first opening at one side of the first shroud having the fan mounted thereon is coupled to a vent opening on a housing of the computer for convection. A first opening at one side of the second shroud is coupled to a second opening at the other side of the first shroud to form an upper air passage and a lower air passage. Fins on one side of the CPU are partially enclosed by an L-shaped frame element extended from the second shroud so as to cause an air current generated by the fan to accelerate through the upper and lower air passages for cooling the CPU and other electronic elements therearound.
