Problems solved by technology

[0004] When the control device 10 is just started, it cannot send the speed control signal 102 in time, causing the fan 13 to run at the highest speed, and the starting current is too large
In addition, when the failure of the fan 13 is eliminated (for example, the fan 13 is stuck by a foreign object), when the control device 10 is restarted, the speed control signal 102 cannot be sent in time, so the fan 13 is operated at the highest speed. If the starting current is too large, the above two situations will cause unnecessary energy waste on the client system side and the temperature rise of the fan under high-speed operation.

Embodiment Construction

[0030] A fan system and its control device according to a preferred embodiment of the present invention will be described below with reference to related drawings.

[0031] see figure 2 As shown, a control device 20 of a fan system according to a preferred embodiment of the present invention can be used in cooperation with an external system 2 , and the fan system has at least one fan 3 . The control device 20 receives a starting voltage 91 and a warning signal 92 . Wherein, the starting voltage 91 is provided by an external voltage source V, and the control device 20 starts to act after receiving the starting voltage 91 . The control device 20 includes a start control unit 21 , a drive unit 22 and a speed control unit 23 .

[0032] When receiving the start voltage 91, the start control unit 21 generates a start control signal 93, the start control signal 93 in this embodiment can be a high potential signal, and after a predetermined time, the start control unit 21 stops se...

Abstract

The present invention relates to a control device of fan system. Said control device is used for receiving starting voltage and warning signal. Said fan system has at least one fan, and said control device includes a starting control unit and a drive unit. Said drive unit is electrically connected with said starting control unit and said fan respectively. Said invention also provides the working principle of said control device of fan system and its concrete operation method.

Description

technical field [0001] The present invention relates to a fan system and its control device, in particular to a fan system started at a lower rotating speed and its control device. Background technique [0002] Generally speaking, an electronic system has a fan system for heat dissipation, and the fan system has a control device and at least one fan, so that the electronic system can control the speed of the fan through the control device, so that the fan of the fan system can The rotating speed of the fan is adjusted according to the actual operating condition of the electronic system. For example, when the fan system is applied to an external system and the processor usage ratio of the external system is high, the heat generated by it is relatively high. speed to meet cooling requirements. Conversely, when the processor is in an idle state, the rotation speed of the fan can be relatively reduced, so as to achieve the effect of energy saving. [0003] see figure 1 As sh...
