- Ubuchwepheshe be-Microchannel buthuthukisa ukudluliselwa kokushisa endaweni yokuxhumana ekhuliswe kakhulu ngevolumu encishisiwe.
- Ukusetshenziswa kwayo kusuka ekupholiseni umoya kwezimboni kanye ne-HVAC kuya ekupholiseni kwangaphakathi kwama-semiconductors kanye nezikhungo zedatha.
- Inikeza izinzuzo ezibalulekile njengokunciphisa ukusetshenziswa kwefriji, isisindo esiphansi sesakhiwo, kanye nokumelana nokugqwala okuphezulu.
Uma wake wazibuza ukuthi imishini yesimanje ingaba kanjani namandla kakhulu ngenkathi ithatha isikhala esincane, impendulo ivame ukuba sekuphathweni kwayo kokushisa. Ukupholisa iziteshi ezincane sekufikile ukuze kuphazamise izindlela zendabuko, okunikeza igxathu elikhulu phambili ekusebenzeni kahle kwamandla kanye nokwakhiwa kwesistimu yokupholisa, okushiya izindlela eziphelelwe yisikhathi esezingenelanga.
Empeleni, sikhuluma ngokuvela kwesimo lapho ubunjiniyela bukwazile ukunciphisa imigudu lapho uketshezi lugeleza khona, okwenza ukushintshana kokushisa kusheshe futhi kusebenze kahle kakhulu. Akusekho nje ngokufutha umoya ngefeni, kodwa mayelana nokwenza ngcono yonke imilimitha yendawo engaphezulu ukuze ukushisa kuphele ngokushesha—into ebalulekile kukho konke kusukela ekupholiseni komoya kwezimboni kuya ku-chip yekhompyutha yanamuhla.
Buyini ngempela ubuchwepheshe be-microchannel?
Ukuze sikuqonde kahle lokhu, sidinga kuqala ukubheka izinhlelo zakudala ze-fin-and-tube. Kulezo zinhlelo, i-refrigerant yayihamba ngamapayipi ethusi futhi umoya wawudlula ngamaphini e-aluminium. Inkinga yayiwukuthi kwakukhona ukumelana okuningi kokuthintana futhi isikhala asizange sisetshenziswe ngokugcwele. Ama-microchannel heat exchangers (ama-MCHE) ashintsha umdlalo ngokusebenzisa amapayipi ayisicaba ahlukaniswe ngaphakathi abe iziteshi ezincane, okwandisa indawo yokudlulisa ukushisa endaweni encane kakhulu.
Kula mayunithi, i-refrigerant ingena nge-manifold eyodwa, ihambe nge-microchannels, bese iphuma nge-one. Isici esihlakaniphile kakhulu ama-baffle angaphakathi aphoqa uketshezi ukuthi lujikeleze ngamapayipi izikhathi eziningi , lwandise isikhathi salo sokuhlala futhi luqinisekise ukuthi ukushisa kudluliselwa emaphinini bese kukhishwa emkhathini ngendlela ephumelela kakhulu. Ngaphezu kwalokho, ngoba akhiqizwa kusetshenziswa ama-welding fluxes angaboliyo kanye nama-aluminium alloys, amaphuzu abuthakathaka ezinhlelo ezindala ayasuswa.
Izinzuzo zokuncintisana kunezinhlelo zendabuko
Uma siqhathanisa izinhlelo ze-MCHE nezinhlelo zamapayipi kanye namafin, umehluko uyamangalisa. Okokuqala, zingasebenzisa amandla kahle ngo-20% no-40% . Azigcini nje ngokusebenzisa amandla amancane, kodwa futhi zivumela ukwehla kokushaja kwefriji kufikela ku-50%, okuyizindaba ezinhle kakhulu kokubili esikhwameni sakho kanye nasemvelweni ngokunciphisa umthelela wakho wekhabhoni.
- Ukunciphisa isisindo kanye nomthamo: Lezi zingxenye zingaba nesisindo esingaphansi ngo-60% kunezendabuko, okwenza kube lula kakhulu ukufakwa ophahleni noma ezindaweni ezinesikhala esincane.
- Ukumelana nokugqwala: I-Aluminiyamu inamandla ngokwemvelo, futhi uma ufaka isembozo sekhwalithi, ukuqina kwayo akunakuqhathaniswa.
- Ukugeleza komoya okuthuthukisiwe: Ngenxa yokusebenzisa amaphiko athambile, ukuxokozela kuyancishiswa futhi i-coefficient yokudlulisa ukushisa ephezulu kakhulufuthi kunciphisa umsindo njengoba zivumela ukusetshenziswa kwamafeni amancane.
Kodwa-ke, akuzona zonke izindaba ezinhle. Kubalulekile ukukhumbula ukuthi ukuphathwa kwe-condensate kungaba yinkinga enkulu, njengoba uhlelo oluklanywe kabi lungavimba ukuhamba komoya. Ngaphezu kwalokho, uma kubhekwa ubunzima balezi zinhlelo, iphutha lokuklama ukukhiqiza lingavimbela i-refrigerant ukuthi igeleze kahle, okungenza izinzuzo zayo zingabi khona.
Izicelo zezimboni kanye nezobuchwepheshe obuphezulu
Lobu buchwepheshe abugcini nje kuma-chiller. Ezweni lama-elekthronikhi anamandla, lapho sinama-laser anamandla aphezulu namamojula e-RF, ukupholisa iziteshi ezincane kuyindlela kuphela yokuvimbela izingxenye ukuthi zingancibiliki. Lokhu kuhilela ukusebenzisa izinsimbi zethusi noma ze-ceramic ezineziteshi zesikali se-micrometer lapho amanzi noma i-glycol e-deionized ijikeleza khona, ichitha amakhulu ama-watts ngesentimitha lesikwele.
Emkhakheni wesikhungo sedatha, ama-air cooler e-microchannel ayizingxenye ezibalulekile zokupholisa yonke into kusukela kuma-server racks kuya ezinhlelweni zokucwilisa ngoketshezi. Alungele izindawo ezivaliwe nezihlanzekile, okwenza kube nokulawula okunembile kokushisa ngamafeni e-EC aguqula ijubane lawo ngokuya ngomthwalo wangempela wokushisa, ngaleyo ndlela athuthukise ukusetshenziswa kwamandla.
Unqenqema oluphambili: ukupholisa kwe-semiconductor okuhlanganisiwe
Uma besicabanga ukuthi okungenhla kuyamangalisa, abacwaningi baseSwitzerland bathathe isinyathelo esiqhubekayo ngokudala ama-chip angadingi ukupholisa kwangaphandle. Bakwazile ukuhlanganisa ama-microtubules ngqo ezintweni ze-semiconductor . Esikhundleni sokuzama ukupholisa i-chip ingaphandle, i-coolant igeleza eduze kwe-transistor.
Lolu hlelo luyisimangaliso sangempela sobuchwepheshe, olukwazi ukuqeda ukushisa okungaphezu kuka-1,7 kW ngesentimitha lesikwele ngokusetshenziswa kwamandla amancane. Ngokususa isidingo sama-heat sink angaphandle, inqubo iyonga kakhulu futhi ivumela imiklamo emincane kakhulu , ivula indlela yenkathi entsha yama-supercomputer asebenza kahle namadivayisi eselula.
Ukusimama kanye nokulawula okuhlakaniphile
Umkhuba wamanje ubheke ekusetshenzisweni kweziqandisi zemvelo, njenge-ammonia (R-717) noma i-propane (R-290), ezinomthelela ocishe ungabi khona emvelweni. Uma sihlanganisa lezi ziketshezi nomklamo wesiteshi esincane kanye nohlelo lokulawula lwedijithali olusekelwe kuma-PLC nama-frequency inverters, sithola imishini engagcini nje ngokuphendula, kodwa futhi elindele, izidingo zokupholisa zesitshalo.
Kusukela ezimbonini zokudla nezokwelapha kuya kwezokuthutha ezibandayo, isihluthulelo sisekushintsheni. Izinhlelo zesimanje zingasebenza ngaphakathi kobubanzi obungu-25% kuya ku-100% wamandla azo, zigwema ukwanda kwamandla okuhambisana nemijikelezo yendabuko yokuvula/yokuvala. Lokhu, kuhlanganiswe nokulula kokuhlanganiswa ne-Building Management Systems (BMS), kwenza ubuchwepheshe be-microchannel bube yisinqumo esihlakaniphe kakhulu kunoma iyiphi ingqalasizinda efuna inzuzo kanye nomthwalo wemfanelo wezemvelo.
Ukushintshela kuma-microchannels kumelela ushintsho olufana nolwe-paradigm lapho i-miniaturization kanye nesayensi yezinto zokwakha kuvumela ukusebenza kokushisa okungakaze kubonwe ngaphambili. Kungakhathaliseki ukuthi kusetshenziswa ama-capacitor e-aluminium ezitshalweni ezinkulu zezimboni noma kuhlanganiswa iziteshi zokugeleza enhliziyweni ye-microprocessor, umgomo uyafana: ukukhulisa ukudluliselwa kwamandla ngenkathi kunciphisa umthelela wemvelo kanye nezindleko zokusebenza, ngaleyo ndlela kuhlanganiswa ubuchwepheshe obunamandla kakhulu, obulula, futhi obuhlala isikhathi eside ngasikhathi sinye.
