Problems solved by technology

Therefore, even if the control module provides the same control signal to stop the rotation of different fan modules, the fan drive circuits of different fan modules will have a certain degree of error, that is, there may be a chance that one fan module has stopped rotating, while the other If one fan module is still operating, it may even happen that one fan cannot rotate, while other fans continue to operate, so that the control module thinks that the system is still operating normally
In this case, it is easy to cause uneven heat dissipation, and cause the system circuit to malfunction

Abstract

A heat dissipation system includes a control module, a first fan module and a second fan module. The first fan module is electrically connected to the control module to provide a speed signal to the control module. The second fan module is electrically connected to the control module and the first fan module. The control module provides at least one control signal to control the rotation of the first fan module and the second fan module respectively. The first fan module transmits a first trigger signal to the second fan module, and the second fan module starts to rotate or stops rotating together with the first fan module according to the first trigger signal.

Description

technical field [0001] The invention relates to a heat dissipation system and a fan drive circuit, in particular to a heat dissipation system and a fan drive circuit that can provide high stability. Background technique [0002] With the vigorous development of electronic devices in recent years, cooling systems have been widely used, and it is normal to use multiple fan modules as the design structure of the cooling system. However, to control different fan modules, due to the differences in the control circuit process, the control The method also needs to be adjusted correspondingly, so that different fan modules can act simultaneously as much as possible. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of the rotational speed curve of a general cooling system with multiple fans. exist figure 1 Among them, the rotation speed curve I and the rotation speed curve II are the rotation speed curves of different fan modules respectively. In the rotati...
