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.

A wind guide device for a cooling fan mounted on a CPU of a computer comprising: a first shroud including a first opening at one side, a second opening an opposite side, a coupling element at either side of the second opening, and a snapping element at either corner of the first shroud, the snapping element being above the coupling element and perpendicular to the second opening; and a second shroud including a first opening at one side, the first opening having a diameter smaller than that of the second opening of the first shroud, a second opening at an opposite side, a mating coupling element at either side, a mating snapping element at either side wherein the mating coupling elements and the mating snapping elements are fastened onto the coupling elements and the snapping elements at the second opening of the first shroud respectively, and an L-shaped frame element extended outward from the second opening of the second shroud; wherein the first opening of the first shroud having the fan mounted thereon is coupled to a vent opening on a housing of the computer, the first opening of the second shroud is coupled to the second opening of the first shroud by fastening the mating coupling elements and the mating snapping elements of the second shroud onto the coupling elements and the snapping elements at the second opening of the first shroud respectively for forming an upper air passage and a lower air passage, and fins on one side of the CPU are partially enclosed by the L-shaped frame element of 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. 2. The wind guide device of claim 1, wherein each of the coupling elements is a U-shaped groove. 3. The wind guide device of claim 1, wherein each of the snapping elements is a wing member. 4. The wind guide device of claim 1, wherein the first shroud further comprises a plurality of rib members across the second opening thereof to form a plurality of first channels for concentrating the air current in the first shroud and guiding and hastening the air current generated by the fan at one side of the first shroud therethrough. 5. The wind guide device of claim 1, wherein the first shroud has a substantially square section. 6. The wind guide device of claim 1, wherein each of the mating coupling elements is a projection. 7. The wind guide device of claim 1, wherein each of the mating snapping elements is a flexible arm having a wedge. 8. The wind guide device of claim 1, wherein the second shroud further comprises a plurality of ribs across the second opening thereof to form a plurality of second channels, the ribs being disposed corresponding to the rib members in the second opening of the first shroud. 9. The wind guide device of claim 1, wherein the second shroud is shaped substantially as a bell.
