1図を用いて説明する。[Detailed Description of the Invention] [Background of the Invention] Generally, electronic devices are cooled by using a fan to draw in an external air flow, and after cooling electronic components (heating elements) inside the device with the air flow, the air flow is discharged. It is structured like this. This example will be explained using FIG.

から筐体1が第2図の如く小型化され、操作者10の背
丈より低いものが提案されている。The electronic device 1, for example, the computer shown in FIG.
If the housing 1 is taller than the fan 3 from the ventilation hole 5 on the top surface,
The relatively cold air sucked in from the outside is exhausted from the exhaust port 50 on the bottom side via the internal electronic circuit 2, and the front surface is ergonomically adjusted to the height of the operator 10 (left side in the figure).
An operation panel 40 is provided at the top. In contrast, in recent years,
As the integration of electronic circuits progresses, and for the purpose of introduction into offices, the casing 1 has been downsized as shown in FIG. 2, and a casing 1 that is shorter than the height of the operator 10 has been proposed.

方へ胡気するものがある。The electronic device shown in FIG. 2 has a housing 1 for operational purposes.
An operation box 4 having an operation panel 40 on the top surface is protruded, and a ventilation hole 5 is provided at the upper part of the front surface of the casing. External air sucked by the fan 3 from the ventilation hole 5 is passed through the electronic circuit 2 to the exhaust port 50. The air is exhausted from the bottom of the housing 1. Other examples of similarly short housings include one in which the air taken in by the fan B from the ventilation port 5 at the top of the front is exhausted from the exhaust port 50 at the bottom of the front, as shown in FIG.
As shown in the figure, the air sucked in by the fan 3 from the vent 5 on the lower surface of the housing 1 is once sent to the upper part, and then circulated to the lower part again. There is something to do.

風抵抗が大きく大型のファンを設ける必要があり、送風
効率が悪い。また該送風抵抗が大きいため、騒音が大き
くなり、電子機器が設置される現況に悪影響をおよぼす
。However, in this relatively short casing, since the sucked external air is circulated through the bent pipe, it is necessary to provide a large fan with high air blowing resistance, resulting in poor air blowing efficiency. Moreover, since the air blowing resistance is large, the noise becomes large, which adversely affects the current situation in which electronic equipment is installed.

に排気する電子機器においては、筐体1下面の排気口5
0から排気した空気が床に直接当たって跳ね返り、送風
抵抗が極めて大きく、前記ファンの大型化及び騒音上問
題が太きい。More specifically, in the case of an electronic device that exhausts air into the space under the casing 1 shown in FIG.
The air exhausted from the air directly hits the floor and bounces back, creating extremely high air blowing resistance, leading to problems in terms of the size and noise of the fan.
第3図及び81!4図に示した電子機器は、吸入した外
部空気を筺体1内において2回以上折曲させるため送風
抵抗が大きく、ファンの大型化及び騒音上問題が太きい
。また、操作者に向って排気するため操作者に不快感を
与える。The electronic equipment shown in FIGS. 3 and 81!4 has a large air blowing resistance because the inhaled external air is bent twice or more within the housing 1, resulting in large-sized fans and noise problems. Moreover, since the air is exhausted toward the operator, the operator feels uncomfortable.
本発明は、前記従来技術の問題点を除去することであり
、小型化された背の低い筐体の電子機器において、送風
効率が良く、ファンの小型化及び低騒音化を計ることが
できる電子機器の冷却構造を提供することである。The present invention is to eliminate the problems of the prior art, and is to provide an electronic device that has a small and short housing, has good air blowing efficiency, and can reduce the size and noise of the fan. The purpose is to provide a cooling structure for equipment.

徴とする。In order to achieve the above object, the cooling structure for a housing device according to the present invention includes an air flow passage extending upward from the bottom of the housing, and an air flow passage connected to the upper end of the air flow passage, and exhausting air in a direction substantially opposite to the operator. It is characterized by being equipped with an operation box having an exhaust port.

前面下部に設けても良い。The electronic device shown in FIG. 5 includes a casing 1 having support legs 11 on the bottom surface to form a lower space between it and the floor, and an electronic circuit 2 (heating element) inside the casing 1. , an air flow passage 12 connecting the vent hole 5 on the lower surface of the housing 1 with the upper surface; and a fan 6 provided at the lower end of the air flow passage 12 to suck external air into the air passage 12 from the lower space. , an operation box 44 having an exhaust port 55 provided on the upper surface of the housing 1, connected to the upper part of the air passage 12, and discharging air to the rear (right side of the drawing) space. Similarly, the ventilation path 5 may be provided at the lower front of the housing.

小孔から構成され、筺体1上面の操作ボックス44の。This electronic device sucks external air from the lower space of the housing 1 into the air path 12 through the vent 5 by the fan 6,
The sucked air flows upward through the electronic circuit 2 and is discharged from the exhaust port 55 on the rear surface of the operation box 44. The discharge port 55 of the operation box 44 is composed of a plurality of small holes, as shown in FIG. 6, which is a perspective view of the slave device viewed from the back side.

ができる。The air flow according to this embodiment is carried out along the upward air flow caused by the heat generated by the electronic circuit 20. Therefore, since air resistance is extremely low, the fan 3 can be downsized and noise can be reduced. In addition, external air is sucked in from the lower space formed on the bottom surface of the electronic device, and the operation box 44
Since the air is discharged toward the space inevitably formed behind the housing, cooling can be performed without any problem even if the housing is installed in a place where both sides of the housing are blocked, for example. Furthermore, since the exhaust port 55 is oriented in a vertical direction, it is possible to prevent foreign matter from falling through the exhaust port 55 from having an adverse effect on the electronic circuit 2, and also to prevent one operator 10 from placing some documents at the rear position of the operation box 44. However, the air can be vented without being blocked. Since the exhaust is directed in the opposite direction to the operator 10, it does not cause discomfort to the operator 10 (
Also, in terms of appearance, since the cooling structure is formed as a part of the operation panel box 44, unnatural appearance can also be eliminated.
