The one-to-one standard wind pressure data of rotary speed data.The controller 12 is additionally operable to calculate described first pair according to the table of comparisons
Should be related to, and corresponding relation storage is deposited in memory 14 described.Under the implementation method, the rated rotational frequency data and institute
It is data message when cooling system laying dust degree meets default laying dust degree to state standard wind pressure data.As described above, these
Data message can be processed by the big data in computer model simulation or practical application and obtained, and then according to these data
Information is calculated and obtains the first corresponding relation.As use time increases, when laying dust gradually increases, the controller 12 of cooling system is straight
The first corresponding relation read in memory 14 is connect, for early warning, judges whether laying dust meets default laying dust degree.At this
In implementation method, the rated rotational frequency data and the standard wind pressure data are to prestore data letter in memory 14
Breath.That is pre-set first corresponding relation, simply first corresponding relation need the control of cooling system
Device 12 is calculated.
In other embodiment, it is also possible to before dispatching from the factory, directly by upper main frame according to computer model simulation or
Big data treatment in practical application obtains the rated rotational frequency data and the standard wind pressure data, turns further according to the standard
Fast data are calculated with the standard wind pressure data and obtain the first corresponding relation, by first corresponding relation storage in the storage
Device.After dispatching from the factory, as use time increases, when laying dust gradually increases, the controller 12 of cooling system directly reads memory
The first corresponding relation in 14, for early warning, judges whether laying dust meets default laying dust degree.In this embodiment,
The rated rotational frequency data and the standard wind pressure data are obtained ahead of time for host computer, so precalculated setting first
Corresponding relation, and by first corresponding relation storage in the memory 14 of cooling system.
The controller 12 is used to obtain the second couple between the current rotary speed data and the current wind pressure data
Should be related to, laying dust early warning is carried out according to first corresponding relation and second corresponding relation.
First corresponding relation can be somebody's turn to do as laying dust early warning relation when current wind pressure data and current rotary speed data meet
During the first corresponding relation, controller carries out early warning.Alarm mode can show early warning information by controlling display；Or pass through
Warning device carries out laying dust alarm, audible alarm, indicator light alarm and vibrations alarm lamp；Or send alarm to mobile device
Information, by mobile device display alarm information.In the foregoing description, the rated rotational frequency data and the standard wind pressure data
Between the first corresponding relation for default settings it is good.In other embodiments, the controller 12 is additionally operable to set early warning
Relation, when the current rotary speed data and the current wind pressure data meet the laying dust early warning relation, carries out laying dust pre-
It is alert.A kind of mode is that control 12 has above-mentioned modeling processing function, and above-mentioned early warning relation can be set in order to controller.
In embodiments of the present invention, in order to obtain the current rotary speed data of fan 13, can be gathered by velocity sensor
The current rotary speed data of fan 13.Now, the cooling system also includes：Velocity sensor, the velocity sensor and controller
12 connections, for gathering the current rotary speed data.In other embodiments, can be without setting speed sensor, now
Controller 12 controls the rotating speed of the fan by PWM (impulse modulation) signal, and the controller 12 according to the PWM for believing
Number obtain the current rotary speed data of the fan.

Narrower, blast is bigger.That is, curve 22 represents the first corresponding relation of above-mentioned standard wind pressure data and rated rotational frequency data
Function curve diagram.When the current wind pressure data and the corresponding coordinate points of current rotary speed data of real-time detection are located at curve 22
During upper area, laying dust degree is less than the corresponding laying dust degree of curve 22, without alarm；When the current wind pressure data of real-time detection
And current rotary speed data corresponding coordinate points, when being located at the lower zone of curve 22 or curve 22, laying dust degree is more than curve
22 corresponding laying dust degree, are alarmed.It is specific to its as the corresponding early warning relation of above-mentioned curve 22 can set according to demand
Functional relation is not limited, and when the corresponding curve 22 of early warning relation is closer to curve 21, represents that the sensitivity of laying dust early warning is bigger,
Less laying dust degree can cause the early warning of cooling system, when the corresponding curve 22 of early warning relation is further away from curve 21, represent
The sensitivity of laying dust early warning is smaller, and larger laying dust degree can just cause the early warning of cooling system.
When heat dissipation channel difference, fan difference and different laying dust degree, cause the tool of wind pressure data and rotary speed data
Body exponential function expression formula is different.Wind pressure data can be by linear fit side with the specific index function expression of rotary speed data
Formula is obtained, and the embodiment of the present invention is not specifically limited.
