A fan module is provided in this disclosure. The fan module comprises a fan and a casing. The casing accommodates the fan and includes a first cover and at least one second cover, the second cover is rotatably connected with the first cover at a first location or a second location. A portion of the fan exposed by the second cover at the first location is less than that at the second location.

A fan system includes a fan, a hysteresis circuit including a temperature sensor, a first operational amplifier having a negative input end coupled to the temperature sensor, and a second operational amplifier having a negative input end coupled to an output end of the first operational amplifier and having a positive input end coupled to a power supply for outputting a first voltage when the temperature sensed by the temperature sensor is greater than a first temperature, and for outputting a second voltage when the temperature sensed by the temperature sensor is lower than a second temperature. The fan system further includes a fan switch coupled to the hysteresis circuit and the fan for controlling a rotational speed of the fan according to the first voltage or the second voltage outputted from the hysteresis circuit. The first temperature is greater than the second temperature.

Fan system with hysteresis character and method thereof

An extendable heat dissipation apparatus includes a base, an extendable heat dissipation member and a connecting element. A normal fin is formed on the base, and the connecting element integrates the extendable heat dissipation member in the apparatus with the base. The extendable heat dissipation member can be extendable to an extending location and can also be stored in a storing location with respect to the base.

Extendable heat dissipation apparatus

A series-connected heat dissipater coupled by heat-pipe used for the interface cards of a computer system. Wherein, a plurality of additional auxiliary dissipaters are provided onto the insertion slots adjacent to the interface cards, and are connected to the main dissipater through heat pipe, hereby effectively solving the heat dissipation problem of the interface cards, so that the main-machine-board will not be bent and deformed due to the overweight caused by the interface cards.
