Benefits of technology

[0009]To achieve the above and other objects, the fan system provided according to the present invention includes a stator assembly and a monitoring and sensing module. The stator assembly includes at least one magnetic sensor unit, a control unit and a rectifier unit. The magnetic sensor unit generates a sensing signal to the control unit, and the control unit is further electrically connected to the rectifier unit. The monitoring and

Problems solved by technology

The accumulated heat results in a relatively high temperature at these areas and can not be easily dissipated from the closed communication chassis and server cabinets.
When the temperature exceeds the range that can be tolerated by the electronic elements of the communication apparatuses and the server appliances, the reliability or service life of the communication apparatuses and the server appliances would be seriously adversely affected.
That is, the temperature distribution in the conventional communication chassis and server cabinets is extremely uneven to largely reduce an overall heat dissipation performance of the communication chassis and the server cabinets.
However, these solutions would inevitably result in bulky and heavy communication chassis and server cabinets.
Under this situation, in the event o

Abstract

A fan system includes a stator assembly and a monitoring and sensing module. The stator assembly is electrically connected to the monitoring and sensing module, and the latter includes at least one sensor unit, at least one monitoring unit and a signal processing unit. The sensor unit of the monitoring and sensing module senses an operating state of the fan system, and the signal processing unit processes the sensing results of the sensor unit and actively generates a warning in the event of an abnormal operating state of the fan system, so as to protect the fan system against an operation failure due to any abnormal operating state and thereby reduce the fan system's maintenance cost.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a fan, and more particularly to a fan system capable of actively generating a warning in the event of an abnormal operating state of the fan to avoid a fan operation failure and reduce fan maintenance cost.BACKGROUND OF THE INVENTION[0002]It is known that electronic communication apparatuses and server appliances are normally enclosed in individual communication chassis and server cabinets, respectively. When the electronic elements in the communication apparatuses and the service appliances operate, they produce heat at the same time. Since the communication chassis and the server cabinets are closed enclosure, the heat produced by the electronic elements of the communication apparatuses and the server appliances during operation thereof tends to accumulate and gather at some particular areas in the communication chassis and the server cabinets. The accumulated heat results in a relatively high temperature at these areas ...
