Description
Technical field
The present invention is about a kind of fan (fan), particularly about a kind of fan that initiatively adjusts the size of air port or wind inlet in operation process on demand.
Background technique
Along with system's miniaturization and integrated, and in order to allow each electronic component is maintained in the normal operational temperature scope in the system, often simultaneously the electronic component more than 2 places is dispelled the heat with single fan with 2 above exhaust outlets.
Yet because the heat that electronic component running everywhere the time is produced is not quite similar, even electronic component also can be along with operation situations such as idling, normal, full speed everywhere, and the big situation of the temperature difference everywhere takes place.When tradition is met this kind situation, be to adopt the mode that improves rotation speed of the fan, make the highest electronic component of temperature be able under normal temperature, operate.Yet the shortcoming of this kind mode is the air output that the synchronous increase of meeting does not need the zone of high radiating effect like this, and the increase of the waste in activation source, noise content, even the shortening of fan life.
Summary of the invention
Therefore, for addressing the above problem, the present invention proposes a kind of fan, adjusts the size of air port or wind inlet on demand with active in operation process, and changes the discharge quantity of fan of this exhaust outlet or the input air quantity of this wind inlet.
The present invention also proposes a kind of fan, operates energy waste and noise content significantly to reduce, even prolongs fan life.
For this reason, the invention provides a kind of fan, comprise at least one fan frame, at least one impeller and at least one active flow regulator.This fan frame has at least two exhaust outlets, and this impeller is located in this fan frame.This active flow regulator is arranged on this fan frame, initiatively to change the size of this one of them exhaust outlet with demand.
The present invention provides a kind of fan in addition, comprises at least one fan frame, at least one impeller and at least one active flow regulator.This fan frame has at least two wind inlets, and this impeller is located in this fan frame.This active flow regulator is arranged on this fan frame, initiatively to change the size of this one of them wind inlet with demand.
The present invention provides a kind of fan again, comprises at least one fan frame, at least one impeller and at least one active flow regulator.This fan frame has at least one wind inlet and at least one exhaust outlet, and this impeller is located in this fan frame.This active flow regulator is arranged on this fan frame, initiatively to change the size of this wind inlet or the size of this exhaust outlet with demand.
In sum, in fan of the present invention, because wind inlet or exhaust outlet place are provided with this active flow regulator, thus can in operation process, initiatively adjust the size of air port or wind inlet on demand, and change the air quantity of exhaust outlet or wind inlet.
In addition, when the present invention has the fan of a plurality of wind inlets or exhaust outlet,
Because wind inlet or exhaust outlet place are provided with this active flow regulator, thus the air quantity of each exhaust outlet or wind inlet can in operation process, initiatively be changed on demand, and significantly reduce running energy waste and noise content, even prolong fan life.
For above-mentioned and other purposes of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below:
