Embodiment
See also shown in Fig. 1 to 4, the utility model is a kind of radiator fan that speed-changing is adjusted mode that has, it comprises: radiator fan 1 and control module 2, wherein this control module 2 is by a power supply 20 power supplies, comprise that a rotating-speed control circuit 21 and switches switch 22, when this change-over switch 22 switches to the first conducting contact 221, this rotating-speed control circuit 21 can with one be arranged on rotating speed on the housing 11 of this radiator fan 1 and adjust button 23 and be electrically connected, the rotating speed of this radiator fan 1 is adjusted by the rotating speed adjustment button 23 that is arranged on this radiator fan 1, and when this change-over switch 22 switches to the second conducting contact 222, this rotating-speed control circuit 21 can be electrically connected with a temperature module 24 that is arranged at the near-thermal source, the rotating speed that makes this radiator fan 1 is by 2 sensed temperature of this temperature module, automatically adjust the rotating speed on this radiator fan 1, and order is when this change-over switch 22 switches to the 3rd conducting contact 223, this rotating-speed control circuit 21 can with one be arranged at and adjust button 25 as the rotating speed on the exterior case 3 such as main frame housing and be electrically connected, just the user can adjust button 25 and directly carry out the rotating speed adjustment by being arranged on rotating speed on the external shell 3.
Above-mentioned change-over switch 22, can be arranged on the housing of this radiator fan 1, or ornamental being arranged at as on the exterior case such as computer host box 3, the user can directly cut this change-over switch 22 in 3 groups of exterior case, so that select to adjust the pattern of radiating fan rotation speed.
As shown in Figure 4, control module 2 of the present utility model, be after this change-over switch 22 is switched selection rotating speed adjustment modes, processor U1, U2, U3 through rotating-speed control circuit 21 judge, handle, to excite inductive coil L1, L2, thereby the mover of this radiator fan of driven in rotation, promptly radiator fan can rotate according to the rotating speed that the user manually turns, or adjusts the rotating speed of this radiator fan automatically with the temperature that this temperature module 24 records.Rotating speed disclosed in the utility model is adjusted button 23,25, can be electronic packages such as variable resistor, and this temperature module 24 can be a thermistor.
Because the disclosed radiator fan with speed-changing adjustment mode of the utility model, the producer just can pass through the switching of this change-over switch 22 according to client's demand when dispatching from the factory, make the rotating speed of radiator fan 1 form following three kinds of patterns and purposes:
1. when change-over switch 22 switches to the first conducting contact 221, this rotating-speed control circuit 221 can with one be arranged on rotating speed on the housing 11 of this radiator fan 1 and adjust button 23 and be electrically connected, the rotating speed of this radiator fan 1 is adjusted by the rotating speed adjustment button 23 that is arranged on this radiator fan 1, this fundamental purpose is according to requirement of client, adjust the demand rotating speed of button 23 adjustment by this rotating speed after, just be arranged in the exterior case 3 such as computer host box, after computing machine activates, this radiator fan 1 just rotates with certain speed, because it is to be hidden in this exterior case 3 that this rotating speed is adjusted button 23, therefore generally speaking, after computing machine dispatches from the factory, just do not adjust use for general user.
2. when this change-over switch 22 switches to the second conducting contact 222, the temperature module 24 that this rotating-speed control circuit 21 and one is arranged at the near-thermal source is electrically connected, the rotating speed that makes this radiator fan 1 is by 24 sensed temperature of this temperature module, automatically adjust the rotating speed on this radiator fan 1, at this moment, the rotating speed of radiator fan just is an automatic adjustment state, and the user just can't be at computer host box footpath self-adjusting radiating fan rotation speed.
3. when computing machine dispatches from the factory, when this change-over switch 22 is switched to the 3rd conducting contact 223, because this rotating-speed control circuit 21 and one is arranged at as the adjustment of the rotating speed on the exterior case 3 such as main frame housing button 25 and is electrically connected, therefore the user just can adjust button 25 and directly carries out the rotating speed adjustment in installing rotating speed on the housing 3 externally, and must not take exterior case apart as computer host box, this mainly provides generally must control user's use of adjusting temperature in the computer host box at any time, when the user raises via the assembly temperature in the main frame of the temperature control display discovery keyholed back plate of device, can dial the rotating speed that changes on the exterior case 3 in good time and adjust the rotating speed that button 25 promotes this radiator fan 1, improve radiating efficiency in good time, when the user is positioned at a low-temperature condition as if the assembly temperature of finding institute's keyholed back plate certainly, just can dial the rotating speed that changes on the exterior case 3 and adjust the rotating speed that button 25 reduces this radiator fan 1, to save the use of the energy.
Therefore, the radiator fan with speed-changing adjustment mode provided by the utility model just can be because of different regions client's demand, manufacturer does not need to purchase the radiator fan of different size rotating speed again, in order to assembling operation, and the handling of goods and materials of sharp factory, and show its novelty and practicality.
Because the utility model selects radiating fan rotation speed to adjust the pattern of mode by this change-over switch 22, no matter be which kind of form, the utility model does not need to pull out other no for the time being adjustment assembly (known, if in the time of need be with manual adjustment, thermistor must be pulled out), be beneficial to the user in changing, switch required adjustment rotating speed pattern voluntarily in the future, on using for the user, very human nature, facility.
Structure disclosed in the utility model, shape can modified application under spirit of the present utility model and category, the utility model is not limit certainly.
