Patent ID: 7911781

Claim:
An electronic device comprising: a housing defining a receiving space and an opening communicating said receiving space with the outside environment, said housing including a power socket disposed in said receiving space; a plurality of heat-dissipating fins disposed in said receiving space of said housing; a heat-dissipating fan including a power plug portion corresponding to said power socket of said housing, said heat-dissipating fan being mountable in said receiving space of said housing through said opening so as to provide a single air flow channel across said heat-dissipating fins, said power plug portion being coupled to said power socket upon insertion of said heat-dissipating fan into said receiving space; wherein said heat-dissipating fan is mounted within said receiving space of said housing such that air outside said housing is pulled in through a plurality of air inlets and an air supply opening, is blown across said heat dissipating fins and exhausted out of said housing through an air exhaust opening and a plurality of air outlets, thereby defining said single air flow channel; wherein said housing includes a first coupling unit, said heat-dissipating fan including a second coupling unit coupled to said first coupling unit; wherein said housing includes a horizontal first base wall, and a second base wall extending upwardly from one side of said first base wall, said opening being formed in said second base wall, said heat-dissipating fan including a first sidewall coupled to said second base wall; wherein said housing further includes a barrier plate extending upwardly from said first base wall and spaced apart from said second base wall, said heat-dissipating fan further including a second sidewall disposed opposite to said first sidewall and abutting against said barrier plate, said power socket being provided on and projecting from said barrier plate, said power plug portion being provided on said second sidewall; wherein said first base wall includes a guide groove extending to said opening, said heat-dissipating fan further including a guide rail connected slidably to said guide groove; and wherein said first coupling unit includes a retaining groove formed in an outer surface of said second base wall, and a screw hole formed in said second base wall, and said second coupling unit includes a tab formed on said first sidewall to engage said retaining groove, and a screw, said tab including a through hole formed therein and corresponding to said screw hole, said screw extending through said through hole to engage said screw hole.
