Embodiment
As shown in Figure 1, the communication apparatus radiating device that this is routine is made up of fan frame A and fan frame B, and 2 groups of fan mount structures are identical, backup each other.Its composition comprises fan, energy supply control module, fault detection unit and logic control element.In this example, every group of fan frame comprises 4 desk fans, and every desk fan is connected with electric power system by energy supply control module.Fault detection unit links to each other with fan, the operating state of fan detected in real time, and with testing result input logic control unit.Logic control element is according to the signal of fault detection unit input, and the operating state of fan frame is judged, and the driving power control module is switched the work of fan frame.
When installation and design, a plurality of fans directly can be fixedly mounted on the fan frame, if wherein certain fan damages, then pull up whole fan frame and change.This example is designed to each independently pluggable fan sub module to fan, changes if only need pull up corresponding fan sub module when wherein certain fan damages, and need not to pull up whole fan frame.
Energy supply control module is mainly hot plug and designs.As the fan frame of consumable accessory, in the operation and maintenance process, need to change and clean, even in equipment operation, also must accomplish the hot-plug fan frame that do not shut down; But in fan frame when plug,, because fan powers on suddenly, startup moment of fan electromotor can produce the rush of current than the big several times of fan nominal operation electric current.Owing in some large-scale computer cabinet equipments, a plurality of fans are installed in the fan frame, the fan frame is understood the operating state that directly influence power supply at the rush of current of plug moment introducing, thereby jamming equipment normally moves.Therefore, be necessary to add energy supply control module, carry out the slow upward electric control of fan.
