Embodiment
As Fig. 1,2, shown in 3, the two regulation and control of computer power source supply device tool of the present utility model fan airstream device, its power supply unit 1 is provided with a main fan 11 in the front, wherein the one side top or the back side are provided with a secondary fan 12 in addition to reach other, and on main fan 11 1 side surfaces on the power supply unit 1 front housing, be provided with outside adjusting knob of a main fan or manual button 112, the outside adjusting knob of main fan or manually button 112 connect mutually with main fan 11, main fan 11 is had can allow user's simple and convenient by the outside with manual or adjust the rotating speed function voluntarily via light instrument.
When system temperature descends, main fan 11 rotating speeds also descend automatically, simultaneously and can adjust the outside adjusting knob of main fan or manually button 112 and regulation and control main fan 11 rotating speeds height with manual mode by the outside, in the hope of try to achieve appropriate balance between heat radiation and noise, its power supply unit than single fan has increased adjustable function.
Structure of the present utility model, when secondary fan 12 meets fault, then main fan can remedy its heat sinking function automatically and the user more can via the outside adjusting knob of main fan or manually button 112 improve the rotating speed of main fans 11, increase rate of air circulation, with balance and reduce intrasystem temperature, avoid system overheat to damage, it obviously can increase the life-span and the reliability of integrated member than the power supply unit of single fan.
Moreover, this pair fan 12 is linked on the power supply unit 1 by its power line terminal 121, and by ambient temperature sensing circuit 122 controls of being located at power supply unit 1 inside, as shown in Figure 5, it can rise and when quickening rotating speed and temperature and descending and reduce rotating speed according to the internal system temperature, when main fan 11 faults, system rises because of air mass flow deficiency temperature, then secondary fan 12 can improve rotating speed automatically, in view of the above, it can carry out complementary action with main fan 11, reaches accurate reduction temperature, avoids system overheat to damage.
Shown in Figure 10 and 13, the embodiment's schematic representation when it is installed on vertical type and the horizontal type host computer 2 for the utility model power supply unit 1 by different way.
In sum, the utility model mainly provides the structure and the external adjustable rotation speed of the fan function of double fan, make conventional power source supply and system radiating problem be obtained good settling mode, the utility model power supply unit 1, its main fan 11 is designed to adjust suitable rotating speed voluntarily according to need at any time, and the design of secondary fan 12, then can remedy the deficiency of main fan 11, or in main fan 11 during at stop state, power supply unit 1 can continue low-speed running, so can reach high-reliability, the optimum of high stability and low consumption electric energy, and the position of secondary fan 12, the utility model is not limited in the top of power supply unit, is arranged at thereafter and also can.
