Description

Electronic device {ELECTRONIC DEVICE}

The present invention relates to an electronic apparatus having a cabinet and electronic components disposed therein.

BACKGROUND ART Electronic devices generally contain various electronic components for realizing functions according to the electronic devices in a box-shaped cabinet. Among these electronic apparatuses, electronic components accompanying heat generation exist in the cabinet, and a cooling fan is provided to cool the electronic components and to prevent the inside of the cabinet from becoming hot due to heat from the electronic components. In addition, there is an electronic device in which a vent port is provided in the cabinet, and heat is removed from the heat generating electronic component, and the heated air is discharged from the exhaust port.

For example, a notebook personal computer (hereinafter, abbreviated as "notebook PC") includes a CPU, other heat generating electronic components, and many other electronic components, and includes a main unit having a keyboard on its upper surface, and a display screen. And a display unit hinged to the main body unit so as to be opened and closed, the main body unit has a fan for cooling the CPU and other heat-generating electronic components, and exhausts air from an exhaust port provided in the cabinet side of the main body unit. It is.

From the recent trend toward higher performance and smaller size of notebook PCs, it becomes a problem where the exhaust port is installed in the cabinet of the main unit. Generally, various parts, such as a CD / DVD charger, a memory card charger, various types of connectors, an audio jack, are arrange | positioned at the left and right sides of a main body unit cabinet, and it is a very complicated state. In addition, the rear side of the main unit unit cabinet is similarly complicated, and the battery for driving the notebook PC is often disposed at the rear of the main unit, and in this case, the arrangement of the connector to the rear side, etc. is considerably limited. There is also. Since there is an operator in front of the main body unit cabinet, heated air cannot be discharged from the front side of the main body unit cabinet.

Under these circumstances, the number of parts placed on the side of the cabinet is increasing due to the increasing performance and the size of the side is narrower as the size is reduced and the thickness is reduced. It is getting very difficult. This trend is common not only in notebook PCs but also in various types of electronic devices.

An object of the electronic device disclosed in the present invention is to enable sufficient air cooling inside the cabinet even when high performance, small size, and thinness are advanced.

An electronic device disclosed in the present invention includes a cabinet having an upper surface, a lower surface, and side surfaces connecting the upper and lower edges of the upper and lower surfaces to surround the upper and lower surfaces over a round, and an electronic component disposed inside the cabinet. As an electronic device,

The cabinet has an exhaust port opened at a position away from the side of the cabinet on the lower surface of the cabinet, and has a fan inside the cabinet for discharging air from the exhaust port. And a projection for supporting the cabinet in a state of being placed on a flat plate in a raised state.

According to the electronic device disclosed in the present invention, since the exhaust port is provided on the lower surface which has a larger area than the side surface and the arrangement is relatively free compared to the side surface, the exhaust port having a sufficient mouth area can be provided. In addition, since the projection is provided, a gap is secured between the bottom surface of the electronic device and the lower surface of the cabinet, particularly at the rear side, to secure a flow path of air discharged from the exhaust port. Therefore, according to the electronic device disclosed in this invention, it is suitable for high performance, small size, and thinness, and can ensure sufficient air cooling capability.

Here, in the electronic device disclosed in the present invention, the fan discharges air toward the rear of the cabinet, and guides the air discharged from the fan at an angle downward, and from the exhaust port to the outside of the cabinet at an angle downward. It is preferable to further provide a guide member for discharging.

With this structure, the air discharged from the exhaust port as a whole flows toward the rear of the cabinet, thereby preventing the heated air discharged from the exhaust port from being blown off to the operator.

In addition, in the electronic device disclosed in the present invention, the cabinet has an expansion protrusion that extends downward and extends from side to side behind the bottom surface of the cabinet, and each of the protrusions is provided on each of the left and right sides of the expansion protrusion at a position overlapping the expansion protrusion. The exhaust port may be provided at a position ahead of the expansion protrusion, adjacent to the expansion protrusion.

In the back of the cabinet, a battery for driving the electronic device is often mounted, and the battery is large in size, and an expansion protrusion may be formed as described above. In addition, not only the battery but also the cabinet may be made thin in the front side, and the expansion protrusion may be formed in the rear side to secure a large volume of the cabinet.

In the case of a cabinet having such an expansion projection, the flow path of air discharged from the exhaust port is secured by placing the projection at a position overlapping the expansion projection and lifting the expansion projection when it is placed on the floor. Also, in this case, by installing the exhaust port at a position ahead of the expansion protrusion adjacent to the expansion protrusion, the air discharged from the exhaust port flows backward through the expansion protrusion, or flows into the left and right along the expansion protrusion, Branching into various flow paths ensures a smooth flow.

The electronic device disclosed in the present invention may be a first cabinet having a keyboard on an upper surface thereof, and further comprising a second cabinet having a display screen and attached to the first cabinet so as to be openable and closeable.

That is, the electronic device disclosed in the present invention can be suitably applied to a notebook PC.

In this case, it is preferable that the second cabinet is attached to the first cabinet so as to be openable and close to the rear of the first cabinet. In a small electronic device, a usage form in which the user grasps both rear edges of the first cabinet of the electronic device with both hands is adopted so that the keyboard can be operated while viewing the display screen. In this mode of use, the user can operate the keyboard by holding the first cabinet without blocking the exhaust vents.

According to the electronic device disclosed in the present invention, it is possible to ensure a sufficient air cooling capability while complying with the request for high performance, small size, and thinning.
