Izinga lemveliso ye-chip kwishishini lokwenziwa kwe-IC linxulumene ngokusondeleyo nobukhulu kunye nenani lamasuntswana omoya afakwe kwi-chip. Umbutho omhle wokuhamba komoya unokuthatha iinqununu eziveliswa ngumthombo wothuli kude negumbi elicocekileyo ukuqinisekisa ukucoceka kwegumbi elicocekileyo, oko kukuthi, umbutho wokuhamba komoya kwigumbi elicocekileyo udlala indima ebalulekileyo kwizinga lesivuno sokuveliswa kwe-IC. Uyilo lwentlangano ye-airflow kwigumbi elicocekileyo kufuneka lifezekise ezi njongo zilandelayo: ukunciphisa okanye ukuphelisa i-eddy current kwi-flow field ukuphepha ukugcinwa kweengqungquthela ezinobungozi; gcina umgangatho woxinzelelo olufanelekileyo ukuthintela ungcoliseko olunqamlezayo.
Amandla okuhamba komoya
Ngokomgaqo wegumbi elicocekileyo, imikhosi esebenza kwiinqununu ibandakanya amandla amaninzi, amandla eemolekyuli, umtsalane phakathi kweengqungquthela, amandla okuhamba komoya, njl.
Amandla okuhamba komoya: ibhekisa kumandla omoya obangelwa kukuhanjiswa, ukubuya komoya, ukuhamba komoya kwe-thermal convection, i-artificial stirring, kunye nezinye ii-airflows ezinezinga elithile lokuhamba ukuthwala amasuntswana. Kulawulo lobuchwephesha lwemeko yendawo ecocekileyo yegumbi, amandla okuhamba komoya yeyona nto ibalulekileyo.
Iimvavanyo zibonise ukuba kwintshukumo yokuhamba komoya, amasuntswana alandela intshukumo yokuhamba komoya phantse ngesantya esifanayo. Ubume bamasuntswana emoyeni buchongwa kukuhanjiswa komoya. I-airflows echaphazela iincinci zangaphakathi zibandakanya ikakhulu: ukuhamba komoya (kubandakanya ukuhamba komoya okuphambili kunye nokuhamba kwesibini), ukuhamba komoya kunye ne-thermal convection airflow ebangelwa ngabantu abahambahambayo, kunye nokuhamba komoya okubangelwa yinkqubo yokusebenza kunye nezixhobo zoshishino. Iindlela ezahlukeneyo zokubonelela ngomoya, i-speed interfaces, abaqhubi kunye nezixhobo zoshishino, kunye neziganeko ezibangelwa kumagumbi acocekileyo zizo zonke izinto ezichaphazela inqanaba lokucoceka.
Izinto ezichaphazela umbutho wokuhamba komoya
1. Impembelelo yendlela yokubonelela ngomoya
(1). Isantya sokubonelela ngomoya
Ukuqinisekisa ukuhamba komoya okufanayo, isantya sokunikezelwa komoya kufuneka sibe yinto efanayo kwigumbi elicocekileyo elingaqhelekanga; indawo efileyo yendawo yokubonelela ngomoya kufuneka ibe yincinci; kunye nokuhla koxinzelelo kwi-ULPA kufuneka kwakhona kube yinto efanayo.
Isantya esilinganayo sokubonelela komoya: oko kukuthi, ukungalingani kokuhamba komoya kulawulwa ngaphakathi kwe ± 20%.
Indawo encinci efileyo kwindawo yokubonelela ngomoya: kungekhona nje kuphela ukuba indawo yendiza yesakhelo se-ULPA iyancitshiswa, kodwa kubaluleke ngakumbi, i-FFU yemodyuli kufuneka yamkelwe ukwenza lula isakhelo esingafunekiyo.
Ukuqinisekisa ukuhamba komoya okuthe nkqo, ukhetho loxinzelelo lwesihluzi lubaluleke kakhulu, lufuna ukuba ilahleko yoxinzelelo kwisihluzi ayinako ukutenxa.
(2). Ukuthelekisa phakathi kwenkqubo yeFFU kunye nenkqubo ye-axial flow fan
I-FFU yiyunithi yokubonelela ngomoya enefeni kunye nesihluzi (ULPA). Emva kokuba umoya ufunxelwe yi-centrifugal fan ye-FFU, uxinzelelo oluguquguqukayo luguqulwa lube luxinzelelo lwe-static kumbhobho womoya kwaye luvuthelwe ngokulinganayo yi-ULPA. Uxinzelelo lomoya kwisilingi luxinzelelo olubi, ukuze kungabikho luthuli luya kuvuza kwigumbi elicocekileyo xa isihluzo sitshintshwa. Iimvavanyo zibonise ukuba inkqubo ye-FFU iphezulu kwi-axial flow fan fan ngokubhekiselele kwi-uniformity outlet, i-airflow parallelism kunye ne-index ye-ventilation esebenzayo. Oku kungenxa yokuba ukuhambelana komoya kwenkqubo yeFFU kungcono. Ukusetyenziswa kwenkqubo ye-FFU kunokwenza ukuhamba komoya kwigumbi elicocekileyo lilungelelaniswe kakuhle.
(3). Impembelelo yolwakhiwo lweFFU ngokwayo
I-FFU ikakhulu yenziwe ngabalandeli, izihluzi, izixhobo zesikhokelo sokuhamba komoya kunye namanye amacandelo. I-ultra-high-effective filter ULPA isiqinisekiso esibaluleke kakhulu sokuba igumbi elicocekileyo linokufezekisa ukucoceka okufunekayo koyilo. Izinto zokucoca ziyakuchaphazela ukufana kwendawo yokuhamba. Xa i-coarse filter material okanye i-laminar flow plate yongezwa kwindawo yokucoca, i-outlet flow field ingenziwa lula.
2. Impembelelo yesantya esahlukileyo sojongano lococeko
Kwigumbi elifanayo elicocekileyo, phakathi kwendawo yokusebenza kunye nommandla ongasebenziyo we-vertical unidirectional flow, ngenxa yokumahluko kwisantya somoya kwi-outlet ye-ULPA, umphumo odibeneyo we-vortex uya kuveliswa kwi-interface, kwaye olu jongano luya kuba yindawo yokuhamba komoya enesiphithiphithi kunye nobukhulu obukhulu be-air turbulence. Amacandelo anokuthi adluliselwe kumphezulu wesixhobo kwaye angcolise izixhobo kunye namaqhekeza.
3. Impembelelo yabasebenzi kunye nezixhobo
Xa igumbi elicocekileyo lingenanto, iimpawu zokuhamba komoya kwigumbi ngokubanzi zihlangabezana neemfuno zoyilo. Nje ukuba izixhobo zingene kwigumbi elicocekileyo, ukuhamba kwabasebenzi kunye neemveliso zihanjiswa, ngokuqinisekileyo kuya kubakho imiqobo kumbutho wokuhamba komoya. Ngokomzekelo, kwiikona eziphumayo okanye kwimida yezixhobo, irhasi iya kutshintshwa ukuze yenze indawo ephazamisayo, kwaye ulwelo olukuloo ndawo aluthwalwa lula yigesi, ngaloo ndlela lubangela ungcoliseko. Ngexesha elifanayo, ubuso besixhobo buya kufudumala ngenxa yokusebenza okuqhubekayo, kwaye i-gradient yeqondo lokushisa iya kubangela indawo yokuphinda ibuyele kufuphi nomatshini, oya kwandisa ukuqokelela kweengqungquthela kwindawo yokubuyisela. Ngexesha elifanayo, ukushisa okuphezulu kuya kubangela ukuba amaqhekeza abaleke ngokulula. Isiphumo esiphindwe kabini sikhulisa ubunzima bokulawula ukucoceka okuthe nkqo kwe-laminar. Uthuli oluvela kubaqhubi kwigumbi elicocekileyo kulula kakhulu ukunamathela kwii-wafers kule mimandla yokubuyisela kwakhona.
4. Impembelelo yomgangatho womoya wokubuya
Xa ukuchasana komoya obuyayo odlula emgangathweni kuyahluka, ukuhluka koxinzelelo kuya kuveliswa, ukwenzela ukuba umoya uya kuhamba kwicala lokunciphisa, kwaye umoya ofanayo awuyi kufumaneka. Indlela yoyilo yangoku edumileyo kukusebenzisa imigangatho ephakamileyo. Xa izinga lokuvula imigangatho ephakanyisiweyo i-10%, isantya sokuhamba komoya kwindawo ephakamileyo yokusebenza kwegumbi sinokusasazwa ngokulinganayo. Ukongezelela, ingqwalasela engqongqo kufuneka ihlawulwe kumsebenzi wokucoca ukunciphisa umthombo wongcoliseko lomgangatho.
5. I-Induction phenomenon
Into ebizwa ngokuba yi-induction phenomenon ibhekisela kwinto yokuba ukuhamba komoya kwicala elichaseneyo lokuhamba okufanayo kuveliswa, kwaye uthuli oluveliswa kwigumbi okanye uthuli kwindawo engcolileyo esondeleyo lunyanzelwa kwicala elinyukayo, ukwenzela ukuba uthuli lungcolise i-chip. Oku kulandelayo zizinto ezinokwenzeka zoqheliso:
(1). Ipleyiti eyimfama
Kwigumbi elicocekileyo kunye ne-vertical unidirectional flow, ngenxa yokudibanisa eludongeni, ngokuqhelekileyo kukho iipleyiti ezinkulu ezingaboniyo eziza kuvelisa i-turbulence ekuhambeni kokubuya kwendawo.
(2). Izibane
Izibane zokukhanyisa kwigumbi elicocekileyo ziya kuba nefuthe elikhulu. Ekubeni ukushisa kwezibane ze-fluorescent kubangela ukunyuka komoya, akuyi kubakho indawo ephazamisayo phantsi kwezibane ze-fluorescent. Ngokuqhelekileyo, izibane kwigumbi elicocekileyo zenzelwe kwimo ye-teardrop ukunciphisa impembelelo yezibane kwintlangano yomoya.
(3.) Izikhewu phakathi kweendonga
Xa kukho izikhewu phakathi kwezahlulo ezinamaqondo ahlukeneyo okucoceka okanye phakathi kwezahlulo kunye neesilingi, uthuli olusuka kwindawo eneemfuno eziphantsi zokucoceka lunokudluliselwa kwindawo ekufutshane kunye neemfuno zokucoceka okuphezulu.
(4). Umgama phakathi komatshini kunye nomgangatho okanye udonga
Ukuba umsantsa phakathi komatshini kunye nomgangatho okanye udonga luncinci kakhulu, luya kubangela isiphithiphithi se-rebound. Ngoko ke, shiya isithuba phakathi kwezixhobo kunye nodonga kwaye uphakamise umatshini ukuze ugweme ukuvumela umatshini ukuba uthinte umhlaba ngokuthe ngqo.
