Abstract

A heat-dissipating casing of an electronic apparatus having an input device, an output device, and a printed circuit board connected with the input device and the output device is disclosed. The heat-dissipating casing includes a metal extruded casing having at least four surfaces to form a space, a first opening and a second opening, wherein the space is used for receiving the printed circuit board, a first side plate fixed to the metal extruded casing to cover the first opening and having a first hole for securing the input device, and a second side plate fixed to the metal extruded casing to cover the second opening and having a second hole for securing the output device, thereby dissipating the heat generated from the electronic apparatus and equalizing the surface temperature of the electronic apparatus.

Claims

1. A heat-dissipating casing of an electronic apparatus having an input device, an output device, and a printed circuit board connected with said input device and said output device, comprising:

a metal extruded casing having at least four surfaces to form a space, a first opening and a second opening, wherein said space is provided for receiving said printed circuit board;

a first side plate fixed to said metal extruded casing to cover said first opening and having a first hole for securing said input device; and

a second side plate fixed to said metal extruded casing to cover said second opening and having a second hole for securing said output device,

thereby dissipating the heat generated from said electronic apparatus and equalizing the surface temperature of said electronic apparatus.

2. The heat-dissipating casing according to claim 1 wherein said electronic apparatus is an adapter, a power supply or a transformer.

3. The heat-dissipating casing according to claim 1 wherein said metal extruded casing is made of aluminum or copper.

4. The heat-dissipating casing according to claim 1 wherein said metal extruded casing is formed integrally.

5. The heat-dissipating casing according to claim 1 wherein said metal extruded casing has plural dents or fins formed on said surfaces thereof.

6. The heat-dissipating casing according to claim 1 wherein said metal extruded casing has plural heat-dissipating holes.

7. The heat-dissipating casing according to claim 1 further comprising a cover covering a part of said metal extruded casing.

8. The heat-dissipating casing according to claim 7 wherein said cover is made of plastic.

9. The heat-dissipating casing according to claim 7 wherein said cover has plural heat-dissipating holes.

10. The heat-dissipating casing according to claim 7 wherein said cover comprises at least one fixing element for fixing to said metal extruded casing in a removable manner.

11. The heat-dissipating casing according to claim 10 wherein said fixing element is a spring piece for biasing against said surface of said metal extruded casing, so that said cover is fixed to said metal extruded casing in a removable manner.

12. The heat-dissipating casing according to claim 1 wherein said first side plate and said second side plate are made of aluminum, copper or plastic.

13. The heat-dissipating casing according to claim 1 wherein said first side plate is fixed to said metal extruded casing to cover said first opening by screws.

14. The heat-dissipating casing according to claim 1 wherein said second side plate is fixed to said metal extruded casing to cover said second opening by screws.

15. A heat-dissipating casing of an electronic apparatus having an input device, an output device, and a printed circuit board connected with said input device and said output device, comprising:

a metal extruded casing having at least four surfaces to form a space, a first opening and a second opening, wherein said space is provided for receiving said printed circuit board;

a first side plate fixed to said metal extruded casing to cover said first opening and having a first hole for securing said input device;

a second side plate fixed to said metal extruded casing to cover said second opening and having a second hole for securing said output device; and

at least one cover covering a part of said metal extruded casing for preventing a user from directly touching said electronic apparatus and being hurt by the heat generated from said electronic apparatus.

16. The heat-dissipating casing according to claim 15 wherein said cover is made of plastic.

17. The heat-dissipating casing according to claim 15 wherein said cover has plural heat-dissipating holes.

18. The heat-dissipating casing according to claim 15 wherein said cover comprises at least one fixing element for fixing to said metal extruded casing in a removable manner.

19. The heat-dissipating casing according to claim 18 wherein said fixing element is a spring piece for biasing against said surface of said metal extruded casing, so that said cover is fixed to said metal extruded casing in a removable manner.

20. The heat-dissipating casing according to claim 15 wherein said metal extruded casing is made of aluminum or copper.
