Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small computer, and more particularly to a technique effective when applied to a small computer provided with a display and a keyboard in a computer body, for example, a notebook personal computer.

[0002]

2. Description of the Related Art In recent years, small computers, such as personal computers, have greatly increased the amount of heat generated in the devices as their performance has been greatly improved. At the same time, there is a demand for smaller and thinner devices to enhance portability. Therefore, there is a need for a technique for efficiently cooling the device without impairing portability.

As a conventional method for cooling a personal computer, such as a notebook computer, having a display and a keyboard in a computer main body, heat generated from a heating element such as a heating element is conducted to a heat radiating plate such as a metal and diffused. Method,
Alternatively, there is a method of discharging heat to the outside of the device by operating the fan in the device.

[0004] For example, when natural cooling is performed without using a fan or the like, it is desirable that there is a sufficient space around the heating element or the heat radiating plate. However, the space has become difficult to obtain with the reduction in size and thickness of the device. In order to solve this problem, for example, in Japanese Patent Application Laid-Open No. H10-333782, a cover around the bottom of the apparatus main body can be opened and closed to create a space around the heat generating portion inside the apparatus main body, thereby improving cooling performance. It was possible to raise.

Further, as a cooling structure using a fan, there is a type in which a vertical axial flow type fan (hereinafter, referred to as an axial flow fan) is arranged on the back or side of the apparatus as shown in FIG. The axial fan 71 sucks heated air inside the apparatus in the same direction as the rotating shaft, and discharges heat out of the apparatus in the same direction. This type of fan 71
Since air is sucked / discharged in the same direction as the rotating shaft, cooling can be performed efficiently.

Further, there is a thin type device in which a flat suction / side discharge type fan (hereinafter, referred to as a thin fan) as shown in FIG. 8 is mounted. The thin fan 72 sucks air from the upper surface of the fan in the same direction as the rotation axis, and discharges air from the side surface perpendicular to the rotation axis. In this type, since the fan 72 is mounted by laying it sideways, it is suitable for reducing the thickness of the apparatus main body.

In the technique disclosed in Japanese Patent Application Laid-Open No. 10-333777, the fan can be used as a part of a movable tilt leg so that the axial flow fan can be stored or set up. ing.

[0008]

By the way, in the prior art as described above, first, as described in Japanese Patent Laid-Open No.
In the computer of Japanese Patent No. 3782, natural cooling is performed without using a fan or the like. Therefore, it is becoming difficult to sufficiently cool the heat generated by the computer which is increasing more and more.

Next, in a cooling structure using a fan, when an axial fan as shown in FIG. 7 is used, in order to perform efficient exhaust, the fan is mounted in an upright state in the apparatus. I have to do it. Therefore, when trying to cool a device that generates a large amount of heat, it is necessary to use a fan with a large flow rate, and the height of the fan itself increases,
The thickness of the device itself will increase accordingly.
Therefore, if this type of fan is used, cooling can be performed efficiently, but there is a problem that it is difficult to make the device thinner.

Further, in the cooling structure of FIG. 8 described above, the cooling portion of the device in which the thin fan is mounted is shown. However, since the fan is placed horizontally, the thickness of the device body can be reduced. is there. However, the thin fan draws air from the upper surface of the fan, bends the air flow by 90 degrees, and discharges the air from the side of the fan. Therefore, since the air flow is sharply bent, the air flow is not smooth but has resistance. Further, since the opening of the discharge port is small, the efficiency is inferior to that of the axial fan. Therefore, in order to increase the cooling capacity, it is necessary to increase the rotation speed of the fan or increase the flow rate by increasing the diameter of the fan.
However, this causes inconveniences such as a loud noise when driving the fan and a necessity to increase the mounting area. However, this type of fan is suitable for thinning the device.

The above-mentioned Japanese Patent Application Laid-Open No. 10-333777
In the technology disclosed in Japanese Patent Application Laid-Open No. H11-107, the mounting position of the fan is limited in order to make the fan a part of the tilt leg. Also,
Power of a motor or the like or operation for opening and closing the fan is necessary for opening and closing the tilt leg built in the fan.

Therefore, the present invention has been proposed to solve such problems of the conventional technology.
That is, an object of the present invention is to provide a small-sized computer which can be efficiently cooled without impairing the thickness of the apparatus main body.

[0013]

That is, the present invention relates to a cooling structure of a small computer in which a display unit can be opened and closed with respect to an apparatus main body via a hinge part. The axial fan accommodated in the main body rises, and at the same time, some of the external components of the main body move and open. This makes it possible to store the axial fan with good cooling efficiency in the thin device main body, and to open the cover of a part of the device main body when the device is used to create a space in the device main body, and to remove the heat from the heat generating portion. Heat can be efficiently dissipated. At the same time, the use of the axial fan enables more efficient heat discharge. No special power or operation is required for these series of operations, and they can be achieved only by the operations necessary for using the small computer to open the display unit.

Further, in the above-mentioned small computer,
When the display unit is opened, the display unit moves up and the fan rises. This makes it possible to improve the cooling performance of the apparatus main body without increasing the thickness of the apparatus main body by the same operation as described above.

Further, in the above-mentioned small computer, when the display unit is opened, the keyboard unit moves upward, so that a wider space is formed in the apparatus main body, so that the cooling performance of the apparatus main body is further improved. It becomes possible.

Further, in the above-mentioned small computer, when a part of movable components is the top cover, the top cover can be opened in conjunction with opening the display unit. Also, in the case of the bottom cover, the bottom cover can be opened in conjunction with opening the display unit.
Thereby, it is possible to improve the cooling performance of the apparatus main body by discharging the heat from the heat generating portion in the top direction or the bottom direction.
