「産業上の利用分野Ｊ
この発明は、マイクロプログラム制御方式により情報処
理を行う情報処理装置をファンにより強制的に冷却する
ための強制空冷制御方式に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application J This invention relates to a forced air cooling control method for forcibly cooling an information processing device that processes information using a microprogram control method using a fan.
「従来の技術」
従来、情報処理装置では装置内に実装された複数のファ

室での設置とは異なり、環境温度の悪化、装置からの発
生騒音が大きな問題となっている。In addition, as a cooling method that does not always drive the fan, there is a method in which a temperature-responsive relay is built into the device and the fan starts to be driven when the temperature rise reaches a certain value. , information processing devices have become smaller and cheaper, and can now be installed in all sorts of places. As a result, unlike when installed in a computer room, deterioration of the environmental temperature and noise generated by the equipment have become major problems.

が大きくなる欠点があった。In the conventional method described above, the method of constantly driving the fan had the drawback of increasing noise because the number of fans and the air volume were increased in accordance with the heat generation within the information processing device and the rise in environmental temperature.

あった。In addition, in systems equipped with temperature-responsive relays, it is necessary to install temperature-responsive relays at important points within the equipment, and in order to drive the fan at the optimal temperature, it is necessary to install a large number of relays. When the relays are driven at the same time, the noise generated becomes louder, and it is difficult to set the reaction temperature of the relay to one type, so several types of reaction temperature relays are required.

グとすることが可能である。"Means for Solving the Problems" The forced air cooling control system of the present invention includes a fan control section that drives and controls a plurality of DC fans mounted on an information processing device, and the fan control section receives information from a microprocessor section. It has a configuration that drives and rotates only the fans instructed by the fan control command, or stops its rotation. Therefore, it is possible to drive only one fan in sequence, or to drive all the fans at the same time. It can be driven in the following pattern. Furthermore, the drive timing is set by a microprogram, so it can be driven at regular intervals, driven in accordance with the detection of a specific state, the connection state of peripheral devices, or the operating state, and even if the temperature distribution inside the device is known by pre-simulation. It is possible to set the timing to be arbitrary, such as sequential driving.
