A heat dissipating device used for dissipating heat from a heat generating device (100) in a computer. The heat dissipating device includes a fan bracket (20), a fan (27) received in the fan bracket, and an air duct (50). The fan bracket defines a fan opening (25), and has a supporting member (233).
A heat dissipating device used for dissipating heat from a heat generating device (100) in a computer. The heat dissipating device includes a fan bracket (20), a fan (27) received in the fan bracket, and an air duct (50). The fan bracket defines a fan opening (25), and has a supporting member (233). The supporting member has a flat board (2333). A pair of retaining portions (2335) is formed on opposite edges of the flat board respectively. The flat board defines a retaining hole (2337) therein. The air duct defines an airflow passageway and has a top wall (51) and two opposite sidewalls extending from the top wall. A securing member (553) extends from one of the sidewalls is retained between the two retaining portions. A post (5535) protruding from the securing member is engaged in the retaining hole for cooperatively retaining the air duct to the fan bracket.

What is claimed is: 1. A heat dissipating device for dissipating heat from a heat generating device in a computer, the heat dissipation device comprising: a fan bracket defining a fan opening, the fan bracket having a supporting member, the supporting member having a flat board and a pair of retaining portions formed on opposite edges of the flat board respectively, the flat board defining a retaining hole therein; a fan received in the fan bracket adjacent to the fan opening; and an air duct defining an airflow passageway, the air duct having a top wall and opposite sidewalls extending from the top wall, a securing member extending from one of the sidewalls retained between the two retaining portions, and a post protruding from the securing member engaged in the retaining hole. 2. The heat dissipating device as described in claim 1, wherein each retaining portion has a slanted guiding flange for facilitating guiding the securing member to seat on the flat board. 3. The heat dissipating device as described in claim 1, wherein the passageway has an inlet facing the fan opening and an outlet facing the heat generating device, and the outlet is wider than the inlet. 4. The heat dissipating device as described in claim 1, wherein a plurality of gaskets is formed on the top wall of the air duct. 5. A computer heat dissipating assembly comprising: a chassis; a motherboard positioned in the chassis; a fun bracket mounted in the chassis adjacent to the motherboard, the fan bracket having a supporting member the supporting member having a flat board and a pair of retaining portions formed on opposite edges of the flat board respectively; a heat generating device arranged on the motherboard; a fan received in the fan bracket for blowing air toward the heat generating device; an air duct retained between the fan bracket and the heat generating device with an airflow passageway for guiding air therethrough, a securing member formed on the air duct being retained on the supporting member by the two retaining portions; and a top cover abutting against the air duct for preventing the air duct from moving upwards, wherein the air duct has a top wall, and two sidewalls extending from two opposite edges of the top wall respectively, and the securing member extends from one of the sidewalls. 6. The computer heat dissipating assembly as described in claim 5, wherein the flat board defines a retaining hole, and the securing member has a post extending through the retaining hole for securely retaining the air duct. 7. The computer heat dissipating assembly as described in claim 5, wherein each retaining portion has a slanted guiding flange for facilitating guiding the securing member to seat on the flat board. 8. The computer heat dissipating assembly as described in claim 5, wherein the passageway has an inlet facing the fan bracket and an outlet facing the heat generating device, and the outlet is wider than the inlet. 9. The computer heat dissipating assembly as described in claim 5, wherein a plurality of gaskets is formed on the top wall abutting against the top cover. 10. The computer heat dissipating assembly as described in claim 5, wherein the motherboard has two extension connectors, and the air duct has a foot retained between the two extension connectors for mounting the air duct to the motherboard. 11. A computer comprising: an enclosure having a bottom panel and a top panel; a motherboard mounted on the bottom panel; a fan housing mounted in the enclosure adjacent to the motherboard, the fan housing having a sidewall with an opening defined therein, a supporting member formed on the sidewall, the supporting member having a flat board and a pair of retaining portions formed on opposite edges of the flat board respectively, a retaining hole defined in the flat board, and each retaining portion having a slanted guiding flange; a disk drive bracket arranged on the motherboard; a fan received in the fan housing adjacent to the opening for blowing air toward the disk drive bracket; and an air duct arranged between the fan housing and the disk drive on the motherboard, the air duct and the motherboard cooperatively forming a channel for guiding air to flow therethrough, a securing member formed on the air duct being retained on the supporting member by the two retaining portions, and the securing member having a post extending through the retaining hole for securely retaining the air duct; wherein the slanted guiding flange is facilitated to guide the securing member to seat on the flat board, so that the post of the securing member can be therefore received in the corresponding retaining hole. 12. The computer as described in claim 11, wherein the air duct is sandwiched between the top panel and the motherboard. 13. The computer as described in claim 11, wherein the channel has an inlet coupled to the opening of the fan housing and an outlet coupled to the disk drive bracket, and the outlet is wider than the inlet.
