Ezinhlelweni ezifana namalaser anamandla amakhulu, izinto zikagesi ezisebenza ngogesi, nezinhlelo zokuxhumana, ukusetshenziswa kwamandla okwandayo kanye namazinga okuhlanganiswa kwenze ukuphatha okushisayo kube yinto ebalulekile ethinta ukusebenza komkhiqizo, ubude bempilo, nokuthembeka. Eceleni kokupholisa kwesiteshi esincane,ukupholisa isiteshi esikhulukuye kwavela njengekhambi elisebenzayo lokupholisa uketshezi. Isakhiwo sayo esilula, izindleko eziphansi, kanye nokunakekelwa okulula kuyenza ifaneleke kakhulu izimo eziningi zezimboni.
1. Kuyini Ukupholisa Kwesiteshi Esikhulu?
Ukupholisa amashaneli amakhulu kuhilela ukusetshenziswa kwamashaneli okupholisa amakhudlwana (imvamisa ebangeni eliyimilimitha) eyakhelwe kumapuleti okupholisa noma amamojula. Lawa mashaneli aqondisa uketshezi olupholisayo—imvamisa amanzi angcolile, izixazululo ezisekelwe ku-glycol, noma ezinye izinto zokupholisa ezimbonini—ngesistimu ukuze kususwe ukushisa okukhiqizwa phakathi nokusebenza kwedivayisi. Uma ihlanganiswe neluphu yokupholisa amanzi, lokhu kusetha kunika amandla ukulawula okushisayo okuqhubekayo nokusebenzayo.
2. I-Macro-Channel vs. Isiteshi Esincane: Umehluko Obalulekile
| Isici | Ukupholisa Kwesiteshi Esikhulu | Ukupholisa Kwesiteshi Esincane |
| Usayizi Wesiteshi | I-Millimeter-scale (1mm ukuya kumamm ambalwa) | I-Micrometer-scale (amashumi kuya kumakhulu μm) |
| I-Fabrication Complexity | Iphansi ngokuqhathaniswa | Idinga ukunemba okuphezulu kwemishini |
| Ukumelana nokugeleza | Okuphansi, uketshezi lugeleza kalula | Iphezulu, idinga umfutho wephampu ophezulu |
| Ukushintshanisa Ukushisa Ngempumelelo | Okumaphakathi, kulungele ukushisa okuphakathi nendawo | Iphezulu, ilungele ukushisa okushisayo |
| Izindleko | Phansi | Phezulu |
| Uhlelo lokusebenza olujwayelekile | Ukushisa okuphakathi kuya kokuphansi, amasistimu okuthembeka okuphezulu | Ukuminyana kwamandla aphezulu, imithombo yokushisa yendawo |
3. Izinzuzo zokupholisa kwesiteshi esikhulu
Nakuba ukusebenza kahle kwayo kokushisa kuphansi kunezixazululo zesiteshi esincane, ukupholisa kwesiteshi esikhulu esikhulu kunikeza izinzuzo ezimbalwa eziphawulekayo:
①Ukuthembeka okuphezulu:
Iziteshi ezibanzi azijwayele ukuvaleka, zinikeza ukuzinza okuhle kakhulu kwesikhathi eside—ezilungele ukusebenza kwezimboni okuqhubekayo.
②Izindleko zokukhiqiza eziphansi:
Isakhiwo esilula kanye nezinketho zokwenziwa ezihlukahlukene ziyenza ifanelekele ukukhiqizwa ngobuningi.
③Ukulungiswa kalula:
Izikhawu ezinde zokuhlanza, izindleko zokulungisa eziphansi, kanye nezidingo eziqinile zokuhlanzeka kokupholisa.
④Umthamo owanele wokupholisa:
Kumadivayisi anokushintshashintsha kokushisa okumaphakathi, ukupholisa kweshaneli enkulu kugcina amazinga okushisa aphakeme okusebenza kahle futhi kunwebe impilo yedivayisi.
4. Izimo Zokusebenza
Ukupholisa ama-macro-channel kusetshenziswa kakhulu kulezi zindawo ezilandelayo:
①Amamojula we-Laser:
Ikakhulukazi kumalaser aphakathi ukuya kuye kwamandla aphansi noma ama-laser emodi ye-CW, amasistimu eziteshi ezinkulu angaphatha kalula umthwalo oshisayo.
②Amamojula we-elekthronikhi wamandla:
Okufana nama-rectifiers, iziguquli ze-DC-DC, namamojula e-IGBT.
③Ama-amplifiers ezokuxhumana kanye nezinhlelo ze-radar:
Ilungele izindawo eziyinkimbinkimbi ezidinga ukusebenza kwesikhathi eside, okuzinzile.
④Amasistimu okupholisa kumishini yezokwelapha neyezimboni:
Kubandakanya amadivaysi e-semiconductor laser therapy, imishini yokumaka nge-laser, nokuningi.
5. Ukucatshangelwa Okubalulekile Kwedizayini Yokupholisa Kwesiteshi Esikhulu
Isixazululo esiyimpumelelo sokupholisa sesiteshi esikhulu sidinga ukunakwa kulezi zici ezilandelayo:
①Isakhiwo sesiteshi:
Kufanele ithuthukiswe ngokusekelwe ekusabalaliseni komthombo wokushisa wedivayisi ukuze kuzuzwe ukupholisa okufanayo.
②Ukukhetha okubalulekile:
Ithusi, insimbi engagqwali, noma ama-alloys e-aluminium ngokuvamile asetshenziselwa ukuguquguquka kwawo okuphezulu kokushisa nokumelana nokugqwala.
③Izinga lokugeleza nokuhambisana kwephampu:
Idizayini efanele yesivinini soketshezi nokugeleza kokupholisa kuqinisekisa ukushintshaniswa kokushisa okusebenzayo nokuzinza kwesistimu.
④Izixhumi ezibonakalayo ezisezingeni:
Inika amandla ukuhlanganiswa okulula kumadivayisi wekhasimende noma amamojula.
6. Isiphetho
Ukupholisa kweshaneli enkulu kuyaqhubeka nokubamba iqhaza elibalulekile ezinhlelweni zemboni ngenxa yobulula bako, ukwethembeka, kanye nokusinakekela kalula. Kuyisixazululo esingabizi kakhulu futhi esinokwethenjelwa, ikakhulukazi kumasistimu ane-middle to low thermal densities. Njengoba idizayini yedivayisi ithuthuka, izixazululo zamashaneli amakhulu nazo zithuthukela ekuhlanganisweni okuphezulu nokuvumelana nezimo okuthuthukisiwe.
7. Mayelana NATHI
I-Lumispotinikeza ubuchwepheshe obuningi kuzo zombili izixazululo zokuphatha ukushisa kwamashaneli amakhulu kanye namashaneli amancane. Sinikeza amamojula okupholisa enziwe ngokwezifiso ama-lasers, amadivaysi e-optoelectronic, ama-electronics amandla, nokuningi. Ukugxila kwethu kudlulela ngalé kokusebenza okushisayo—sibeka kuqala ukuhlanganiswa kwesistimu nokwethembeka kwesikhathi eside, sihlose ukuletha amasistimu okupholisa asebenza kahle kakhulu, angabizi kakhulu.
Zizwe ukhululekile ukusithinta ukuze ufunde kabanzi mayelana nezixazululo zokupholisa zamashaneli amakhulu namashaneli amancane aklanyelwe izidingo zakho zohlelo lokusebenza!
