Embodiment
Refer to Fig. 1, alarm when the Air Filter pick-up unit 100 of a kind of electronic equipment that embodiment of the present invention provides stops up for the Air Filter at electronic equipment 10, described electronic equipment 10 comprises at least one fan 12, backboard 14, a plurality of single-deck 16 and an Air Filter 18, be understandable that, the quantity of fan 12 can be set according to need voluntarily.As shown in Figure 2, described fan 12 is for described a plurality of single-decks 16 are carried out to wind-cooling heat dissipating, and fan 12 as required can operation work under different gears, is provided with connector 162 in order to be connected with described backboard 14 on a plurality of single-decks 16.
Described Air Filter pick-up unit 100 comprises an environment temperature detecting unit 110, internal temperature detecting unit 120,140, one record cell of fan gear control module 150, collecting unit 160, comparing unit 170 and an Alarm Unit 180.A plurality of single-decks 16 and described fan gear control module 130 are connected with backboard 14 through the connector 162 of single-deck 16, and described environment temperature detecting unit 110, described internal temperature detecting unit 120 and fan gear control module 140 communicate through backboard 14 and described record cell 150, described collecting unit 160, described comparing unit 170 and described Alarm Unit 180.
Environment temperature detecting unit 110 is arranged on the air inlet of 10 electronic equipments for detecting ambient temperature Ta, internal temperature detecting unit 120 is arranged on the single-deck 16 of electronic equipment 10 for detection of the internal temperature Tin of electronic equipment 10, and fan gear control module 140 is for controlling fan 12 in different gear work.
Interior environment temperature Tin and the ambient temperature Ta of electronic equipment 10 correspondences when record cell 150 regulates fan 12 to each gear steady operation for being recorded in, and by each gear of fan 12 and when each gear work internal temperature Tin and the external temperature Ta of corresponding electronic equipment 10 be stored as reference threshold.
The reference threshold of record cell 150 records can be set to record each gear of fan 12 and interior environment temperature Tin and the ambient temperature Ta difference of fan 12 electronic equipment 10 correspondences when each gear steady operation.The reference threshold of record cell 150 records can also be set to record each gear of fan 12 and the ambient temperature Ta of electronic equipment 10 correspondences of fan when each gear steady operation.
Under identical fan gear, when the difference of internal temperature Tin and ambient temperature Ta is greater than reference temperature difference threshold values, is considered as Air Filter and stops up, gap is larger, stops up more serious.Its principle is as shown in Equation (1):
Q=m*Cp*(Tin-Ta) (1)
Wherein, Q is equipment hear rate, and Cp is air ratio thermal capacitance, and m is MAF.Q is constant, and Cp changes less in certain temperature range, is considered as quantitatively, under same rotational speed, if Air Filter stops up, must occur that MAF m reduces, and therefore, the difference of single-deck internal temperature Tin and environment temperature Ta will inevitably become large.
Certainly, carry out gear herein and patrol and examine, except obtaining temperature threshold values, can also evade the heat radiation difference of bringing due to height above sea level.Shown in formula (2):
m=ρ*V (2)
Wherein, ρ is atmospheric density, and V is volume of air flow, and m is MAF.Because height above sea level is different, can there is larger variation in atmospheric density ρ, although under different rotation speeds of the fan, volume of air flow V changes little, but the density variation that height above sea level brings, can cause different regions (Tin-Ta) to differ greatly, carry out gear and patrol and examine and obtain single-deck internal temperature, environment temperature, fan gear, the equipment that can obtain moves on-site parameter, thereby has evaded the impact that height above sea level brings.
That is to say, consider that electronic equipment 10 operates in different Altitude Regions, atmospheric density difference can cause equipment to move difference to some extent, during each electronic equipment 10 start, all needs to carry out reference threshold record to avoid solidification temperature threshold values.
After the temperature parameter that completes each gear of fan and correspondence gathers, system automatically switches to intelligent speed-regulating state, in intelligent speed-regulating running status, real-time gear when collecting unit 160 is worked for timing acquiring fan 12 is normal after electronic equipment 10 temperature stabilization operations and corresponding interior environment temperature and ambient temperature.Be understandable that, duration is regularly set according to actual needs voluntarily.
Be understandable that, intelligent speed-regulating method is according to predefined single-deck upgrade temperature threshold and the temperature threshold that lowers category, fan at electronic equipment detects single-deck internal temperature and fan gear with the rear timing of a certain stabilization of speed operation, and at single-deck internal temperature, be greater than fan while upgrading temperature threshold values and heighten one grade, at fan internal temperature, be less than fan while lowering category temperature threshold values and turn down one grade.Thereby according to intelligent speed-regulating method, fan can seek to meet the fan gear of heat radiation according to environmental change, reduces noise and energy consumption.
Comparing unit 170 carries out corresponding comparison by the reference threshold of the interior environment temperature of the gear of collecting unit 160 each fans 12 that gather, correspondence and external environment condition temperature and record cell 150 records.Alarm Unit 180 determines whether to carry out Air Filter according to the comparative result of comparing unit and stops up alarm and show.
When reference threshold is the interior environment temperature of each gear of fan 12 and fan 12 electronic equipment 10 correspondences during at each gear steady operation and ambient temperature difference, the interior environment temperature of the electronic equipment 10 under the fan 12 work at present gears that comparing unit gathers collecting unit 160 and ambient temperature difference compare with fan 12 corresponding temperature gap threshold value under identical gear of record cell 150 records, under the identical gear of fan 12, when the interior environment temperature that collecting unit 160 gathers and ambient temperature difference are greater than the temperature gap threshold value of record cell 150 records, Alarm Unit 180 carries out Air Filter and stops up alarm and show.Be understandable that, display mode can be undertaken by telecommunication mode.
When reference threshold is the ambient temperature of each gear of fan 12 and fan 12 electronic equipment 10 correspondences during at each gear steady operation, fan gear corresponding under the same external environment temperature that the ambient temperature of electronic equipment 10 works at present that comparing unit gathers collecting unit 160 and corresponding fan gear record with record cell 150 compares, under identical ambient temperature, when the fan gear that collecting unit 160 gathers is greater than the fan gear of described recording unit records, Alarm Unit 180 carries out Air Filter and stops up alarm and show.Be understandable that, display mode can be undertaken by telecommunication mode.
Because the single-deck of working in electronic equipment can be newly-increased to some extent because of actual needs, for better accurately monitoring in real time Air Filter, whether stop up, Air Filter pick-up unit 100 also comprises a single-deck detecting unit 190, when described detecting unit 190 stops up for judging Air Filter at comparing unit 170, whether detected electrons equipment there is not newly-increased single-deck, record cell 150 again records corresponding reference threshold when there is newly-increased single-deck, also be environment temperature detecting unit 110, internal temperature detecting unit 120 and fan gear control module 140 detect corresponding inside and outside temperature record renewal under the different gears of fan again, when not increasing single-deck newly in electronic equipment, collecting unit 160 proceeds timing acquiring relevant parameter.
