1. Technical Field
The present disclosure relates to electronic devices, and particularly, to an electronic device having a case.
2. Description of the Related Art
Electronic devices, such as computer hosts or servers, often include a case for housing components thereof, providing protection from debris and external contaminants, and for shielding electromagnetic interference.
An electronic device often includes a case, an electronic component fixed on and electrically connected to a motherboard, and an airflow guide above the electronic component, including a top cover and two side covers extending from opposite ends of the top cover, cooperatively defining an inlet and an outlet. A fan adjacent to the inlet generates cooling airflow from the inlet to the outlet. However, the airflow guide occupies space in the case at the interior of the electronic device, thereby increasing volume thereof.
Therefore, there is room for improvement within the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views, and all the views are schematic.
Referring to
In the illustrated embodiment, the case 10 includes a box 12, a top cover 14, a first airflow guide member 15, and a second airflow guide member 16. The box 12 is substantially rectangular. The box 12 includes a bottom plate 123, a first side plate 124, a second side plate 125, a third side plate (not labeled) and a fourth side plate (not labeled). The first side plate 124, the second side plate 125, the third plate and the fourth plate extend from a periphery of the bottom plate 123, and cooperatively define an opening 121. The top cover 14 and the box 12 are fixedly attached. The top cover 14 is sealed on the opening 121 of the box 12. The first airflow guide 15 and the second airflow guide 16 are fixed on the top cover 14, and spaced from each other.
The first side plate 124 defines an inlet 126 in an end of the first side plate 124 away from the second side plate 125. The second side plate 125 defines an outlet 127 on an end of the second side plate 125 adjacent to the first side plate 124. In the illustrated embodiment, the inlet 126 includes a plurality of vents 1261 defined in the first side plate 124. The outlet 127 is a fan louver 1271.
The top cover 14 is a rectangular plate. The first airflow guide member 15 and the second airflow guide 16 are disposed on an end of the top cover 14, and cooperatively define a guide channel 17. In the illustrated embodiment, the first airflow guide member 15 is a substantially L-shaped plate; and the second airflow guide member 16 is a planar plate. The first airflow guide member 15 is disposed on an edge of the inner surface of the top cover 14. The second airflow guide member 16 is disposed on a middle portion of the inner surface of the top cover 14. The first airflow guide member 15 and the second airflow guide member 16 are fixed on the top cover 14 by welding. When the top cover 14 seals the opening 121, the guide channel 17 communicates with the inlet 126 and the outlet 127 of the box 12.
In one embodiment, the electronic component 30 is a CPU. The first heat dissipating member 40 and the second heat dissipating member 50 are a plurality of cooling fins. The first heat dissipating member 40 and the second heat dissipating member 50 are fixed on the Southbridge (not shown) and the Northbridge (not shown) of the motherboard 20, respectively.
Referring to
Cooling airflow from the fan 60 enters the inlet 126, absorbs heat from the electronic component 30, the first heat dissipating member 40 and the second heat dissipating member 50, and is exhausted via the outlet 127 by the fan 60.
The first airflow guide member 15 and the second airflow guide member 16 cooperatively define the guide channel 17, such that the electronic component 30 dissipates heat more efficiently. Furthermore, the electronic device 100 requires no dedicated airflow guide, such that the space in the interior of the electronic device 100 is conserved.
It is to be understood that the first airflow guide member 15 and the second airflow guide member 16 can also be fixed on the bottom plate 123, the first side plate 124, the second side plate 125 or another plate.
Referring to
Finally, while the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
