The difference of value carrys out the revolving speed that one or more fans in target area are adjusted by different modes, to make in target area
Temperature value can keep dynamic equilibrium substantially.
Wherein, for example, the normal working temperature value of equipment is 10 DEG C -50 DEG C, and be greater than when equipment local environment temperature or
When equal to 50 DEG C, the operation of equipment will be affected, and when equipment local environment temperature reaches 70 DEG C, the operation of equipment is just
It will receive very big influence, and when equipment local environment temperature reaches 85 DEG C, equipment has the risk burnt, therefore, the present invention
In, multiple preset thresholds are provided with, for the difference of the temperature value in current goal region, above-mentioned steps S102 can be by as follows
Several ways are implemented:
Mode one
When temperature value is greater than or equal to the first preset temperature value, the first preset number fan in target area is improved
Revolving speed；When temperature value is less than or equal to the second preset temperature value, the first preset number fan in target area is reduced
Revolving speed.
For example, the operation of equipment will receive influence, at this point, by target when getting temperature value more than or equal to 50 DEG C
The revolving speed of one or more fan in region is increased to maximum (top) speed, to improve the radiating rate of fan, with it is expected by
Temperature in target area is reduced to 50 DEG C or less.When temperature is less than or equal to 10 DEG C, the operation of equipment also will receive influence,
At this point, reducing the revolving speed of one or more fan in target area, to reduce the radiating rate of fan, temperature is made with expectation
Degree is increased to 10 DEG C or more.
Mode two
When temperature value is greater than or equal to four preset temperature values, the rotational speed regulation of all fans in target area is arrived
Maximum (top) speed.
For example, when temperature value is greater than or equal to 70 DEG C in target area very big influence can be caused to the operation of equipment,
Therefore, when temperature value is greater than or equal to 70 DEG C, directly by the rotational speed regulation of all fans in target area to maximum (top) speed,
So that the radiating rate of fan reaches maximum, it is expected that prestissimo reduces the temperature in target area.
The beneficial effects of the present invention are: the temperature value in target area can be obtained automatically, and according to temperature value intelligence
The revolving speed of multiple fans in target area is adjusted, so that intelligence adjusts the radiating rate of multiple fans, so that fan is in temperature
It revs up when higher, heat radiation speed reduces revolving speed when temperature is lower, reduces radiating rate, had both avoided equipment institute
It is excessively high in regional temperature and influence equipment normal operation, but can reduce the energy when equipment region temperature is lower need not
It is lost.
In one embodiment, above-mentioned steps S102 can be implemented as following steps A1-A2:
In step A1, when temperature value is greater than or equal to the first preset temperature value, first in raising target area is pre-
If the revolving speed of number fan；
In step A2, when temperature value is less than or equal to the second preset temperature value, first in reduction target area is pre-
If the revolving speed of number fan.
In the present embodiment, when temperature value is greater than or equal to the first preset temperature value, first in raising target area is pre-
If the revolving speed of number fan.
For example, the operation of equipment will receive influence, at this point, by target when getting temperature value more than or equal to 50 DEG C
The revolving speed of one or more fan in region is increased to maximum (top) speed, to improve the radiating rate of fan, with it is expected by
Temperature in target area is reduced to 50 DEG C or less.
When temperature value is less than or equal to the second preset temperature value, the first preset number fan in target area is reduced
Revolving speed.
For example, when temperature is less than or equal to 10 DEG C, the operation of equipment also will receive influence, at this point, reducing turning for fan
Speed raises the temperature to 10 DEG C or more to reduce the radiating rate of fan with expectation.
In addition, the operation of fan can also be temporarily ceased when temperature is very low.
Meanwhile Current Temperatures are in the temperature range that can guarantee the normal operation of the equipment in target area, while with
When the difference of the temperature range maximum value is larger, rotation speed of the fan can also be reduced, for example, when temperature is in 20 DEG C, it can also be with
Reduce rotation speed of the fan.
In one embodiment, above-mentioned steps A1 can be implemented as following steps B1:
In step bl is determined, the revolving speed of the first preset number fan is improved to maximum (top) speed；
Above-mentioned steps A2 can be implemented as following steps B2 or B3:
In step B2, the first preset number fan in target area is reduced according to predeterminated frequency and preset step-length
Revolving speed；
In step B3, the gear of the first preset number fan in target area is reduced according to predeterminated frequency, wherein
Gear height is positively correlated with revolving speed speed.
In the present embodiment, when improving rotation speed of the fan, since the power of the more brilliant equipment of performance is usually bigger,
The revolving speed of the first preset number fan is directly adjusted to maximum (top) speed.
Under normal conditions, fan can also directly be started when starting with maximum (top) speed.
Noise is larger when being always maintained at maximum (top) speed in view of fan, and power consumption is higher, and will affect the service life of fan, because
This, if fan keep maximum (top) speed for a period of time after, heat-generating units work region in temperature reach best effort temperature
Degree then gradually reduces the revolving speed of fan, such as reduces fan gear, or reduces rotation speed of the fan with preset step-length.
The beneficial effect of the present embodiment is: the revolving speed of fan is adjusted according to different modes, so that rotation speed of the fan
Adjusted Option it is more diversified.
In one embodiment, as shown in figure 3, this method can also be implemented as following steps S301-S304:
In step S301, after improving the revolving speed of the first preset number fan to maximum (top) speed, judgement
Whether temperature value increases；
In step s 302, when the temperature value increases, by adjacent with the first preset number fan second
The revolving speed of preset number fan is improved to maximum (top) speed；
In step S303, when temperature value does not increase, real-time monitoring temperature value；
In step s 304, when monitoring that temperature value is less than or equal to third preset temperature value, according to predeterminated frequency and
Preset step-length reduces the first preset number fan and second present count adjacent with the first preset number fan
The revolving speed of mesh fan.
In the present invention, when the temperature in target area is just above 50 DEG C, only a part of rotation speed of the fan can be increased to
Maximum (top) speed, for example, as shown in Fig. 2, fan sum be 6, when the temperature in target area is just above 50 DEG C, only improve it
In three fans revolving speed, for example, only improve fan 111, fan 113 and fan 115 revolving speed.
And when the revolving speed of these three fans reaches maximum value, judge whether the temperature value in target area increases.
If temperature increases, illustrate that the heat-sinking capability of these three fans is not sufficient to reduce the temperature in target area, this
When, then three fans (fan 112, fan 114 and fan 116) adjacent with fan 111, fan 113 and fan 115 are turned
Speed is increased to maximum (top) speed.
If the temperature value in target area does not increase, the temperature value in real-time monitoring target area, when monitoring
When temperature value is less than or equal to third predetermined threshold value, stop the revolving speed for improving all fans.For example, when temperature is less than or equal to 30
When spending, illustrate temperature value be in equipment normal work temperature range, and the difference apart from the temperature range maximum value compared with
Greatly, 50 DEG C will not be risen in the short time again, then reduces the revolving speed of all fans according to predeterminated frequency and preset step-length.
In addition, temperature sensor for obtaining temperature value in target area can be it is multiple, for example, heat-generating units
Position is the highest position of temperature in target area, therefore, a temperature sensor can be arranged on each heat-generating units,
The temperature near each heat-generating units can be accurately obtained in this case to detect the temperature of each sensor,
At this point it is possible to which more precise control improves the revolving speed of which fan, for example, the temperature sensor near heat-generating units 119 detects
Temperature near to 119 is increased to 50 DEG C, and since fan 113 and 114 is nearest apart from heat-generating units 119, then it can be by fan
113 and 114 revolving speed is increased to maximum (top) speed, the revolving speed of fan 113 and 114 is increased to maximum (top) speed, if heat-generating units
Temperature near 119 is also increasing, or remains unchanged, at this point, the nearest fan of distance 119 is the fan adjacent with 113
112, and the fan 115 adjacent with 114, at this point, the revolving speed of fan 112 and 115 is increased to maximum (top) speed.
Secondly as the heat-generating units of different vendor's production and the size of fan are usually unmatched, and use this hair
Scheme provided by bright, fan do not need to be aligned with heat-generating units, but are carried out by the channel between adjacent heat-generating units
Heat dissipation, can also reach good heat dissipation effect, therefore, using scheme provided by the present invention, heat-generating units and fan are not necessarily to
One-to-one matching, thus the problem of very good solution fan and heat-generating units are not adapted to.
The beneficial effect of the present embodiment is: after improving the revolving speed of the first preset number fan to maximum (top) speed
After the revolving speed of first preset number fan reaches maximum value, if temperature value also increases, the revolving speed of more multi-fan is improved, from
And the temperature value of target area is reduced by the heat-sinking capability of more multi-fan, so that heat dissipation effect is improved, and when temperature drops
After getting off, then the revolving speed of these fans is no longer promoted, to avoid the unnecessary loss of the energy when temperature value reduces.
In one embodiment, above-mentioned steps S102 can be implemented as following steps:
