An electronic device includes a housing, a spacing structure, a printed circuit board and a fan. The housing has first and second openings. The spacing structure is arranged within the housing for partitioning a space within the housing into an air channel and a receptacle. The air channel is in communication with the first and second openings. The printed circuit board is disposed within the receptacle. The fan is disposed within the air channel for inhaling ambient air via the first opening and exhausting the air via the second opening so as to dissipate heat outside the electronic device.

What is claimed is: 1. An electronic device with a waterproof and heat-dissipating structure, comprising: a housing having first and second openings; a spacing structure arranged within said housing for partitioning a space within said housing into an air channel and a receptacle, said air channel

What is claimed is: 1. An electronic device with a waterproof and heat-dissipating structure, comprising: a housing having first and second openings; a spacing structure arranged within said housing for partitioning a space within said housing into an air channel and a receptacle, said air channel being in communication with said first and second openings, wherein said spacing structure comprising: a heat-dissipating plate; two flanges extended from an inner wall of said housing as to form a trench therebetween; and at least one coupling element for coupling said two flanges to said heat-dissipating plate, thereby sealing said trench defined between said two flanges and partitioning said space within said housing into said air channel and said receptacle; a printed circuit board disposed within said receptacle; and a fan disposed within said air channel for inhaling ambient air via said first opening and exhausting said air via said second opening so as to dissipate heat outside said electronic device. 2. The electronic device according to claim 1 being selected from a group consisting of a power adapter and a charger. 3. The electronic device according to claim 1 wherein said housing comprises an upper housing and a lower housing. 4. The electronic device according to claim 1 wherein said air channel is disposed between an inner wall of said housing and said spacing structure. 5. The electronic device according to claim 1 wherein said housing is made of plastic material. 6. The electronic device according to claim 1 wherein said coupling elements are two adhesive layers for coupling said two flanges to bilateral edges of said heat-dissipating plate, respectively, thereby sealing said trench defined between said two flanges and partitioning said space within said housing into said air channel and said receptacle. 7. The electronic device according to claim 6 wherein said spacing structure further comprises a first rib extended from an inner wall of said housing, adjacent to said first opening and attached onto one side edge of said heat-dissipating plate via said adhesive layer. 8. The electronic device according to claim 7 wherein said first rib is integrally formed with said housing. 9. The electronic device according to claim 7 wherein said spacing structure further comprises a second rib extended from an inner wall of said housing, adjacent to said second opening and attached onto the other side edge of said heat-dissipating plate via said adhesive layer. 10. The electronic device according to claim 9 wherein said second rib is integrally formed with said housing. 11. The electronic device according to claim 1 wherein said two flanges have indentations for receiving and supporting the bilateral edges of said heat-dissipating plate; and said coupling element is a fixing frame having a first portion and a second portion, wherein said first portion biases the bilateral edges of said heat-dissipating plate and said second portion is coupled to said two flanges by supersonic welding, thereby sealing said trench defined between said two flanges and partitioning said space within said housing into said air channel and said receptacle. 12. The electronic device according to claim 11 wherein said spacing structure further comprises a first rib extended from an inner wall of said housing, adjacent to said first opening and having an indentation for receiving and supporting one side edge of said heat-dissipating plate. 13. The electronic device according to claim 12 wherein said first portion of said fixing frame biases said side edge of said heat-dissipating plate, and said second portion of said fixing frame is coupled to said first rib by supersonic welding. 14. The electronic device according to claim 12 wherein said first rib is integrally formed with said housing. 15. The electronic device according to claim 12 wherein said spacing structure further comprises a second rib extended from an inner wall of said housing, adjacent to said second opening and having an indentation for receiving and supporting the other side edge of said heat-dissipating plate. 16. The electronic device according to claim 15 wherein said first portion of said fixing frame biases said the other side edge of said heat-dissipating plate, and said second portion of said fixing frame is coupled to said second rib by supersonic welding. 17. The electronic device according to claim 15 wherein said second rib is integrally formed with said housing. 18. The electronic device according to claim 1 wherein said fan is a blower. 19. The electronic device according to claim 1 wherein said fan is disposed adjacent to said first opening or said second opening. 20. The electronic device according to claim 1 being a portable electronic device.
