Description
Technical field
The utility model is relevant a kind of switching device, refers to especially a kind of one or more fans are connected socket on the motherboard, and is controlled by the fan signal adapting device of pulse width modulation signal (PWM).
Background technology
Utilizing fan to come electron production is dispelled the heat is common a kind of heat radiation gimmick, produce air-flow via fan, hot-air in the operational environment is carried out thermal convection, promptly guiding the low air of temperature enters, produce the heat exchange ringing of heat radiation, make electronic product can keep its task performance with the long-pending heat that reduces operational environment.
And along with the development of CPU technology is tending towards precise treatment, after the CPU of computer-internal operation frequency increased, the heat that CPU sent also can be high more, and demand yet needs to pay attention in heat radiation, therefore at the CPU of high especially heating, also independently go out single fan and dispel the heat; With regard to known techniques, traditional fan control is to see through the temperature that thermistor is detected environment that fan is set up, CPU can produce heat during running, see through the heat guiding of radiating module this moment with CPU, via fan the heat on the radiating module is dispelled again, therefore the heat on radiating module is high more, heat that thermistor is sensed or ambient temperature are just high more, just can operate with high rotational speed this moment avoids cpu temperature too high, yet the rotating speed of real-time fan can't be controlled or obtain to this mode accurately.
And in the follow-up fan Development Technology, except just connecting direct current in the fan input, outside negative voltage and the tach signal, further added a pulse width modulation (Pulse Width Modulation, PWM) signal offers fan, with regard to outward appearance mechanism, it is compared down with general conventional three-wire type fan (two power lines and a holding wire pattern), fan with pwm signal increases to 4 group of pins with number of lead wires, the rotating speed that a pin that has more is used to control fan conducting opportunity and is used for controlling fan, make the rotating speed of its fan can utilize the circulation change of PWM to control accurately and by monitoring in real time in the computer system, along with the different rotating speed of different temperature modulations, therefore has controllability, plurality of advantages such as susceptibility is high and energy-conservation become the new lover in PC system radiating field.
Yet, because having the fan of pwm signal is four pins than the general conventional fan pin of having Duoed, but in the design of general motherboard, only design has one group of socket of pegging graft for four group of pins to provide the cpu fan grafting to use, therefore face the high electronic building brick of more and more radiating requirements (as the VGA radiating module, radiating module of cabinet and access unit radiating module etc.), can't satisfy one by one, its indivedual fans come corresponding one to peg graft, and acquisition utilizes the usefulness of pwm signal management and control, and in the face of this kind situation, known techniques develops the device that a kind of increase has the fan of pwm signal, as shown in Figure 1, known have a plurality of frameworks (as DE202006015577) that can controlled PWM fan, comprise: one first plug 14, in order to connect a connector on the motherboard, this plug 14 has dc voltage input end 9,10, one tach signals 11 and a pulse width modulation (PWM) signal 15; And, one first connecting portion 18 and one second connecting portion 19, it has voltage input end or output 2,3, one tach signals 4 and a pulse width modulation (PWM) signal 15 respectively, wherein first and second connecting portion 18,19 links to each other with first plug 14 via lead 16;
In addition, have one second plug, 8, the second plugs 8 and link to each other with first connecting portion 18 or second connecting portion 19, and have tach signal 11 and connect also input 9 via lead 17.
By said structure,, connect one or more fans and bestow control corresponding or regulation and control to reach by 18,19 amplifications of first and second connecting portion.
In above-mentioned DE202006015577 patent case structure, the fan that these first and second connecting portion 18,19 external power supplies are electrically connected with it, its power source all is to supply with via first plug 14, therefore when connecting two or more fan, can cause load excessive, not only each rotation speed of the fan can't promote, and it is also important that, this power supply also can be seriously influenced to first or second connecting portion 18,19 of the chip on the motherboard (CPU) fan; Easy speech, this DE202006015577 patent can be electrically connected other fan (as VGA radiating module, case radiation group or access unit radiating module) by gene-amplification, influence most important chip (CPU) fan radiating requirements on the contrary, know that in computer system (CPU) is not only the most expensive for this chip, if bad because of dispelling the heat, very easily cause its unstable or damage, not only influence arithmetic speed, useful life is in case damage causes system failure or its replacement expense still can't count.
