1. Macro-Channel Cooling ke Eng?
Pholiso ea li-macro-channel e kenyelletsa tšebeliso ea likanale tse kholoanyane tsa phallo ea pholiso (hangata e le ka har'a limilimithara tse fapaneng) tse hahiloeng ka lipoleiti kapa li-module tsa ho pholisa. Likanale tsena li tataisa maro a pholisang—ao hangata e leng metsi a sa hloekang, litharollo tse thehiloeng ho glycol, kapa li-coliant tse ling tsa indasteri—ka sistimi ho tlosa mocheso o hlahisoang nakong ea tšebetso ea sesebelisoa. Ha e kopantsoe le loop e pholileng ea metsi, seta sena se nolofalletsa ho laola mocheso o tsoelang pele le o sebetsang hantle.
2. Macro-Channel vs. Micro-Channel: Liphapang tsa Bohlokoa
| Sebopeho | Pholiso ea Macro-Channel | Pholiso ea mocha oa Micro |
| Boholo ba Channel | Millimeter-scale (1mm ho isa ho limilimithara tse 'maloa) | Micrometer-scale (mashome ho isa ho makholo a μm) |
| Ho Rata Boqapi | E batla e le tlase | E hloka mochini o nepahetseng haholo |
| Phallo Khanyetso | Mokelikeli o tlaase, o phalla habonolo | E phahame, e hloka khatello e phahameng ea pompo |
| Tšebeliso e Ntle ea Mocheso | E itekanetseng, e loketseng mocheso o mahareng | E phahameng, e loketse mocheso o feteletseng oa mocheso |
| Litšenyehelo | Tlase | E phahameng |
| Tšebeliso e Tloaelehileng | Mocheso o mahareng ho isa ho o tlase, lits'ebetso tse ts'epahalang tse phahameng | Matla a phahameng a matla, mehloli ea mocheso e sebakeng sa heno |
3. Melemo ea Macro-Channel Cooling
Leha ts'ebetso ea eona ea mocheso e le tlase ho feta litharollo tsa li-micro-channel, pholiso ea macro-channel e fana ka melemo e mengata e hlokomelehang:
①Botshepehi bo phahameng:
Liteishene tse pharalletseng ha li na monyetla oa ho koala, li fana ka botsitso ba nako e telele - e loketseng ts'ebetso e tsoelang pele ea indasteri.
②Litsenyehelo tse tlase tsa tlhahiso:
Sebopeho se bonolo le likhetho tse fapaneng tsa masela li etsa hore e tšoanelehe bakeng sa tlhahiso ea bongata.
③Bonolo ba tlhokomelo:
Linako tse telele tsa ho hloekisa, litšenyehelo tse tlase tsa tlhokomelo, le litlhoko tse fokolang tsa bohloeki ba pholiso.
④Bokhoni bo lekaneng ba ho pholisa:
Bakeng sa lisebelisoa tse nang le mocheso o itekanetseng oa mocheso, pholileng ea macro-channel ka katleho e boloka mocheso o nepahetseng oa ho sebetsa le ho lelefatsa nako ea bophelo ea sesebelisoa.
4. Maemo a Kopo
Pholiso ea macro-channel e sebelisoa haholo libakeng tse latelang:
①Li-module tsa laser:
Haholo-holo bakeng sa li-lasers tsa mahareng ho isa ho tse tlase kapa tsa CW-mode, litsamaiso tsa macro-channel li ka sebetsana le mojaro oa mocheso habonolo.
②Li-module tsa elektronike tse matla:
Joalo ka li-rectifiers, li-converter tsa DC-DC, le li-module tsa IGBT.
③Li-amplifiers tsa matla litsamaisong tsa puisano le radar:
E loketse maemo a rarahaneng a hlokang nako e telele, ts'ebetso e tsitsitseng.
④Lisebelisoa tsa ho futhumatsa lisebelisoa tsa bongaka le tsa indasteri:
Ho kenyeletsoa lisebelisoa tsa kalafo ea laser ea semiconductor, mochini o tšoaeang laser, le tse ling.
5. Lintlha tsa Moqapi oa Bohlokoa bakeng sa Pholiso ea Macro-Channel
Tharollo e atlehileng ea ho futhumatsa li-macro-channel e hloka ho ela hloko lintlha tse latelang:
①Sebopeho sa kanale:
E lokela ho ntlafatsoa ho ipapisitsoe le mohloli oa mocheso oa sesebelisoa ho fihlela pholiso e ts'oanang.
②Khetho ea lintho tse bonahalang:
Koporo, tšepe e sa hloekang, kapa li-alloys tsa aluminium hangata li sebelisoa bakeng sa conductivity ea tsona e phahameng ea mocheso le ho hanyetsa kutu.
③Sekhahla sa phallo le ho lumellana ha pompo:
Moralo o nepahetseng oa lebelo la mokelikeli le phallo ea pholiso e netefatsa phapanyetsano e sebetsang ea mocheso le botsitso ba sistimi.
④Maqhubu a tloaelehileng:
E nolofalletsa ho kopanya habonolo lisebelisoa tsa bareki kapa li-module.
6. Qetello
Pholiso ea li-macro-channel e ntse e tsoela pele ho bapala karolo ea bohlokoa lits'ebetsong tsa indasteri ka lebaka la bonolo, ts'epahalo le tlhokomelo e bonolo. Ke tharollo e bolokang chelete e ngata le e ka tšeptjoang, haholo-holo lits'ebetsong tse nang le likhahla tse mahareng ho isa ho tse tlase tsa mocheso. Ha moralo oa lisebelisoa o ntse o fetoha, litharollo tsa macro-channel le tsona li hatela pele ho ea ho kopanyo e phahameng le ho feto-fetoha le maemo.
7. Mabapi le rona
Lumispote fana ka boiphihlelo bo batsi ho litharollo tsa taolo ea mocheso oa macro-channel le li-micro-channel. Re fana ka li-module tsa ho pholisa tse etselitsoeng li-lasers, lisebelisoa tsa optoelectronic, lisebelisoa tsa elektroniki tsa motlakase le tse ling. Tsepamiso ea rona e fetela ka nģ'ane ho ts'ebetso ea mocheso-re beha pele ho kopanngoa ha tsamaiso le ho tšepahala ha nako e telele, ka sepheo sa ho fana ka mekhoa ea ho pholisa e sebetsang hantle, e bolokang chelete e ngata.
Ikutloe u lokolohile ho ikopanya le rona ho ithuta haholoanyane ka litharollo tsa ho pholisa tsa macro-channel le li-micro-channel tse lumellanang le litlhoko tsa kopo ea hau!
