The working principle of the embodiment of the present invention is elaborated as follows:
The present invention contains two kinds of intelligent fan speed-regulating modes, and user according to the carrying out practically environment of equipment actual conditions and equipment, can select suitable speed-regulating mode, and rationally carry out parameter configuration.These two kinds of patterns are ladder speed-regulating mode and return difference speed-regulating mode respectively, are described as follows:
(1) ladder speed-regulating mode
Fig. 2 is the schematic diagram of rotation speed of the fan and temperature under ladder speed-regulating mode, as can see from Figure 2, rotation speed of the fan remains unchanged in certain temperature range, when temperature variation reaches certain step value, equipment carries out fan speed-regulating automatically, namely the shelves speed that equipment is corresponding different under different temperature ranges, the formula of its rotation speed of the fan is: rotating speed=(Current Temperatures-initial temperature)/temperature step value+rotating speed initial value.As long as rationally set these three parameters of initial temperature, initial rotating speed and temperature step value; equipment just can select suitable shelves speed to run according to Current Temperatures automatically; run to reduce device temperature and proterctive equipment with high-grade rotating speed in high temperature environments, run to reduce fan noise and equipment power dissipation with low-grade speed at low ambient temperatures.
(2) return difference speed-regulating mode
Fig. 3 is the schematic diagram of rotation speed of the fan and temperature under return difference speed-regulating mode, and as can see from Figure 3, when temperature is in the operating temperature range that equipment sets, rotation speed of the fan remains unchanged; When temperature is higher than the Maximum operating temperature set, equipment just starts raising speed until the most high-grade speed or device temperature reduce, and rotating speed just effectively can reduce device temperature, to protect equipment after promoting; When temperature is lower than the minimum operating temperature set, equipment just starts reduction of speed until lowest gear or device temperature rise, and so just can reduce fan noise and equipment power dissipation.Under this speed-regulating mode; user does not need to pay close attention to too much speed governing parameter; as long as set the operating temperature of equipment; equipment just can according to current ambient conditions automatic speed regulation; raising speed in high temperature environments; reduction of speed at low ambient temperatures, reduces fan noise and equipment power dissipation while protecting equipment.
Below in conjunction with practical engineering application, illustrate the setting parameter under ladder speed-regulating mode and return difference investigation model.Assuming that in Practical Project, equipment is operated within the scope of 30 ~ 60 degree, and fan speed-regulating gear is 1 ~ 7 grade, and wherein 7 grades of rotating speeds are the highest, and the temperature of equipment in machine room is generally about 45 degree.
When equipment runs under ladder speed-regulating mode, its speed governing parameter can be set to: initial rotating speed is 1 grade, and initial temperature is 30 degree, and temperature step value is 5 degree.The corresponding relation of temperature and rotating speed is as shown in table 1, and as can be seen from the table, it is different that equipment runs shelves speed at the interval internal fan of different temperatures, at high temperature runs with high rotating speed, run at low temperatures with the slow-speed of revolution.When temperature is 45 degree, rotating speed is 4 grades, and this grade of speed is middle-grade rotating speed, also can reduce fan noise, run under being adapted at general building environment while reduction device temperature; When temperature 34 degree and following time rotating speed be 1 grade, under this rotating speed, fan noise is minimum, and the power consumption of equipment is also minimum, is applicable to running at low ambient temperatures; When temperature 60 degree and above time rotating speed be 7 grades, reduction device temperature that can be best under this rotating speed, avoids Yin Wendu too high and damages equipment.
The corresponding relation of table 1, temperature and rotating speed
| Rotating speed | Temperature |
| 1 | 34 degree and following |
| 2 | 35～39 |
| 3 | 40～44 |
| 4 | 45～49 |
| 5 | 50～54 |
| 6 | 55～59 |
| 7 | 60 degree and more than |
Operating temperature range can be set when equipment runs under return difference speed-regulating mode as 45 ~ 50 degree.When temperature higher than 50 time equipment start raising speed, after a period of time, if device temperature still could not reduce, then continue raising speed, be raised to the most high-grade or device temperature always and reduce.When temperature is lower than 45 degree, equipment starts reduction of speed, if device temperature does not rise, then continues reduction of speed, is reduced to lowest gear always.Under return difference speed-regulating mode, equipment is energy stable operation in setting operating temperature range, can feed back immediately and speed governing after temperature changes.It should be noted that: the operating temperature range of setting namely can not excessive can not be too small, excessive then equipment cannot automatic speed regulation, too small, easily produces klystron oscillator.
Be more than illustrating of applying in certain circumstances of intelligent speed-regulating scheme, dissimilar equipment with reference to the method, can rationally arrange speed governing parameter under various circumstances.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these amendments and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then these revise and modification also within protection scope of the present invention.
The prior art that the content do not described in detail in specification is known to the skilled person.
