The disclosure relates to a thin vapor-chamber structure including a first cover and a second cover. The first cover has a first surface and a first clustered pattern. The first clustered pattern is disposed on the first surface, and has a plurality of first protruding stripes spaced apart from each other and extended along a first direction. The second cover has a second surface and a second clustered pattern. The first surface faces the second surface. The second clustered pattern is disposed on the second surface, and has a plurality of second protruding stripes spaced apart from each other and extended along a second direction. The first clustered pattern and the second clustered pattern are partially contacted with each other to form a wick. The lateral walls of the first protruding stripes and the second protruding stripes form a micro-channel meandering between the first surface and the second surface.

A plural-fans driving apparatus is provided to drive a first fan and a second fan, and the first fan and the second fan are three-phase fans. The plural-fans driving apparatus includes a controller, a first three-phase motor driver structure, a second three-phase motor driver structure, and a protection and input interface circuit. The protection and input interface circuit is coupled to the first three-phase motor driver structure and the second three-phase motor driver structure, and protects the first three-phase motor driver structure and the second three-phase motor driver structure. The controller controls the first three-phase motor driver structure to drive the first fan, and controls the second three-phase motor driver structure to drive the second fan.

Plural-fans driving apparatus

A temperature plate device includes a plate body and a bent structure. The plate body includes a first plate and a second plate. A chamber is defined by the first plate and the second plate. The first plate has a first step section. The second plate has a second step section corresponding to the first step section. The bent structure is connected to and traverses the first step section between the first step section and the second step section.

Temperature plate device

A fan is provided. The fan includes a first power terminal, a second power terminal, a filter, a motor driver, a motor, a current sensor, and a controller. The filter includes an amplifying element, a resistor, and a capacitor, wherein a first terminal of the amplifying element is electrically connected to the first power terminal, a second terminal of the amplifying element is electrically connected to a first terminal of the resistor, and the capacitor is electrically connected between the second power terminal and a third terminal of the amplifying element. The motor is electrically connected to the third terminal of the amplifying element. The current sensor detects the current flowing through the motor and correspondingly generates a current sensing signal. The controller outputs a first control signal to the resistor according to the current sensing signal such that the amplifying element operating in an active region.
