置４０を備えている。５０は電源である。In the figure, a plurality of fan devices 20, 20, etc. for forced exhaust air are installed in close proximity to the communication control device 10 that generates heat by performing single circuit exchange, storage and exchange, etc., and the heat generation temperature of the communication control device 10 is adjusted to 1 liter in total. A temperature detector 30 is installed. Furthermore, a fan rotation control device 40 that controls the fan rotation speed of the fan device 20 based on the output of the temperature detector 30 is provided. 50 is a power supply.

減している。If the internal temperature drops, the temperature detector 30 lowers its signal level, and the fan rotation control circuit 40 lowers the fan rotation speed, and if the internal temperature rises, the temperature detector 30 lowers its signal level. , the fan rotation control circuit 40 increases the rotation speed of the fan. This changes the airscape that is generated inside and adjusts the internal temperature to below a certain level. In order to increase reliability, the fans of communication control devices have a redundant configuration, and the number of fans is increasing. Therefore, exhausting the air inside the device with extra air volume inevitably increases noise, but in the present invention, the fan rotation speed is controlled to suppress the excess air volume.
It provides the optimal air volume for the equipment and reduces fan noise.

Optimize internal heat exhaust by controlling the number of fans! S! This has the effect of reducing noise and significantly reducing the noise generated by fan operation by lowering the ambient temperature.
