ぎない。2. Description of the Related Art A conventional portable electronic device is disclosed in Japanese Patent Laid-Open No. 3-184.
As in Japanese Patent No. 108, the display unit that can be freely adjusted has a structure that opens and closes with both sides as the center of gravity. In this structure, the housing is closed and heat is not dissipated. Even if heat dissipation measures have been taken, only small opening windows are opened in the display and main body.

冷による方式で放熱を実現することにある。In electronic devices such as personal computers and workstations, both the desktop type and the portable type, the display unit is a folding type in order to secure a space on the desk when not in use. In this folding structure, a large number of functional elements are mounted in the main body case to achieve high density. As the calculation function and memory capacity increase, the total amount of heat generated in the main case tends to increase. The display section contains a liquid crystal panel and several lights that illuminate the panel. A 10 inch screen light consumes 15-25 watts. For this reason, there is a problem that heat is generated in the main body case and the display case, respectively, and such a temperature rise is likely to cause deterioration of elements and a decrease in the strength of a joint in the main body case and the display. Therefore, it is necessary to realize the heat dissipation and cooling method for the main body case and the display with a simple structure. On the other hand, as a method of promoting heat dissipation, it is conceivable to simply attach a fan to perform forced air cooling, but attaching a fan is not a good method because it increases power consumption and complicates the structure. An object of the present invention is to realize heat dissipation by a simple natural air cooling method that does not use a fan.

は筐体の最上部とした。In order to achieve the above object, the present invention provides an air passage for communicating with both the main body case and the inside of the display so that the hot high-temperature air flows smoothly under the condition of being used. Formed. Since the display unit is used while standing up or tilting at the time of display, the air passage communicating with both is a passage formed vertically in the display unit. The heated air outlet was at the top of the housing.

本体内部の空気の循環，冷却に優れる。When the electronic device is energized to open the display panel for use, the main body case is placed horizontally and the display case is set up. When the device is in use, the opening formed in the bottom of the display case coincides with the opening provided in the upper part of the main body case. There is a small opening in the case near the heating element on the bottom of the case, and air flows in from the outside of the case. Since the display case has an air passage along the case wall, the heated air efficiently flows from the bottom to the top in this vertical or inclined passage,
It flows out through the top opening. In addition, the passage of this display section is attached to the top and bottom, and since it acts as a chimney, it has the effect of sucking heated air from the opening of the main body case,
Excellent in air circulation and cooling inside the body.

ロセッサなどの電子機器に適用できるものである。Embodiments of the present invention will be described below with reference to FIGS. <Embodiment 1> FIG. 1 is a side sectional view of a portable personal computer in which a liquid crystal display panel 2a that rotates around pins 3 on both sides is attached to a main body case 1a. In use, the display panel is vertical to the main case ~ 40 °
Use by tilting. In this state, the opening 1c of the main body case and the opening 2d of the display panel bottom face each other. When the display panel is tilted by 40 °, both openings are exactly the same, but in the vertical state, they are closed by 10 to 20%. A backlight 4 for illuminating the panel is installed behind the liquid crystal display panel 2a. There is a vertical groove between the backlights arranged in the vertical direction of 2 to 4. Opening windows 2c are opened at the ends of these grooves. FIG. 2 shows a state in which the personal computer is not used. Since it has a folding structure, the display panel case overlaps with the main body case and becomes horizontal when folded back. The bottom of the display panel has a convex arc and the body case has a concave shape so that both can rotate without any clearance. The structure is such that the opening at the bottom of the display panel case does not appear on the case surface when folded. Therefore, invasion of dust and dust from the bottom opening of the case is prevented. Further, when the display panel is folded, the opening 2c faces downward, and dust is prevented from entering. <Embodiment 2> FIG. 3 shows a structure in which an opening 1d is provided in the rear portion of the main body case. As shown in FIG. 4, the openings 1d are dispersed and attached to the entire rear side surface of the main body case. The structure is the same as that of the first embodiment except for the rear opening. Due to this rear opening, the air accumulated in the rear portion of the main body case flows out. The case of the folding structure of the natural air cooling system has been described above, but the case is applicable to various materials such as a thin metal plate and plastic. Further, the housing is applicable not only to personal computers but also to electronic devices such as workstations and word processors.

め、自然空冷により熱冷却の効果が大変大きい。According to the present invention, when the electronic device is used, the display panel, which is accommodated in the main body case, is opened and the keyboard and the panel are taken out. In this state, the opening of the body case and the opening of the display panel bottom face each other and are connected. The opening at the end of the display panel is located at the top. Therefore, the air heated in the main body case rises in the display panel through the opening and flows out through the opening outlet. These display channels serve as a chimney because the display panel is almost vertical. Due to the function of the chimney, the air in the main body case is efficiently discharged to the outside. As described above, when the electronic device having the structure is energized and circulated, the air in the device is efficiently circulated, so that the effect of heat cooling by natural air cooling is very large.
