Kuchuluka kwa ma chip mumakampani opanga ma chip kumagwirizana kwambiri ndi kukula ndi kuchuluka kwa tinthu ta mpweya tomwe timayikidwa pa chip. Kukonza bwino kayendedwe ka mpweya kumatha kuchotsa tinthu topangidwa kuchokera ku fumbi kuchokera ku chipinda choyera ndikuwonetsetsa kuti chipinda choyera chili choyera. Izi zikutanthauza kuti, kukonza kayendedwe ka mpweya mu chipinda choyera kumachita gawo lofunikira pakupanga ma chip. Zolinga zomwe ziyenera kukwaniritsidwa popanga kapangidwe ka kayendedwe ka mpweya m'chipinda choyera ndi izi: kuchepetsa kapena kuchotsa mafunde a eddy m'munda woyenda kuti tipewe kusunga tinthu toyipa; kusunga mphamvu yoyenera kuti tipewe kuipitsidwa kwa mpweya.
Malinga ndi mfundo ya chipinda choyera, mphamvu zomwe zimagwira ntchito pa tinthu tating'onoting'ono zimaphatikizapo mphamvu ya unyinji, mphamvu ya mamolekyulu, kukopana pakati pa tinthu tating'onoting'ono, mphamvu ya kuyenda kwa mpweya, ndi zina zotero.
Mphamvu ya mpweya: imatanthauza mphamvu ya mpweya yomwe imabwera chifukwa cha mpweya wotuluka ndi wobwerera, mpweya wotuluka ndi kutentha, kugwedezeka kochita kupanga, ndi mpweya wina womwe umayenda ndi kuchuluka kwa madzi otuluka kuti unyamule tinthu tating'onoting'ono. Kuti ukadaulo wa chilengedwe ukhale woyera m'chipinda, mphamvu ya mpweya ndiyo chinthu chofunikira kwambiri.
Kafukufuku wasonyeza kuti mu kayendedwe ka mpweya, tinthu timatsatira kayendedwe ka mpweya pafupifupi liwiro lomwelo. Mkhalidwe wa tinthu mumlengalenga umatsimikiziridwa ndi kufalikira kwa mpweya. Zotsatira zazikulu za kayendedwe ka mpweya pa tinthu ta m'nyumba ndi izi: kayendedwe ka mpweya (kuphatikizapo kayendedwe ka mpweya koyambirira ndi kayendedwe ka mpweya wachiwiri), kayendedwe ka mpweya ndi kayendedwe ka kutentha komwe kumachitika chifukwa cha anthu oyenda, komanso momwe kayendedwe ka mpweya kamakhudzira tinthu ta m'mafakitale kakuyendera ndi zida zamafakitale. Njira zosiyanasiyana zoperekera mpweya, malo olumikizirana liwiro, ogwiritsa ntchito ndi zida zamafakitale, zochitika zomwe zimayambitsa, ndi zina zotero m'zipinda zoyera zonse ndi zinthu zomwe zimakhudza kuchuluka kwa ukhondo.
1. Mphamvu ya njira yoperekera mpweya
(1) Liwiro la mpweya
Pofuna kuonetsetsa kuti mpweya ukuyenda bwino mofanana, liwiro la mpweya m'chipinda choyeretsera mpweya liyenera kukhala lofanana; malo opanda mpweya pamwamba pa mpweya ayenera kukhala ochepa; ndipo kutsika kwa mphamvu mu fyuluta ya hepa kuyeneranso kukhala kofanana.
Liwiro la mpweya ndi lofanana: ndiko kuti, kusalingana kwa kayendedwe ka mpweya kumayendetsedwa mkati mwa ± 20%.
Pali malo ochepa ouma pamwamba pa mpweya: sikuti malo ozungulira a chimango cha hepa okha ayenera kuchepetsedwa, komanso chofunika kwambiri, FFU yokhazikika iyenera kugwiritsidwa ntchito kuti chimango chowonjezera chikhale chosavuta.
Pofuna kuonetsetsa kuti mpweya ukuyenda molunjika komanso molunjika, kusankha kutsika kwa mphamvu ya fyuluta n'kofunika kwambiri, ndipo ndikofunikira kuti kutayika kwa mphamvu mkati mwa fyuluta kusakondere.
(2) Kuyerekeza pakati pa dongosolo la FFU ndi dongosolo la fan la axial flow
FFU ndi chipangizo choperekera mpweya chokhala ndi fani ndi fyuluta ya hepa. Mpweya umalowetsedwa ndi fani ya centrifugal ya FFU ndipo umasintha mphamvu yamagetsi kukhala mphamvu yosasunthika mu duct ya mpweya. Umatulutsidwa mofanana ndi fyuluta ya hepa. Kupanikizika kwa mpweya padenga ndi mphamvu yoipa. Mwanjira imeneyi palibe fumbi lomwe lidzatulukire m'chipinda choyera mukasintha fyuluta. Mayesero asonyeza kuti dongosolo la FFU ndi lapamwamba kuposa dongosolo la fan la axial flow ponena za kufanana kwa mpweya, kufanana kwa mpweya ndi index ya mphamvu ya mpweya. Izi zili choncho chifukwa kufanana kwa mpweya ndi dongosolo la FFU ndikwabwino. Kugwiritsa ntchito dongosolo la FFU kungathandize kukonza kayendedwe ka mpweya m'chipinda choyera.
(3) Mphamvu ya kapangidwe ka FFU
FFU imapangidwa makamaka ndi mafani, zosefera, malangizo oyendetsera mpweya ndi zinthu zina. Fyuluta ya hepa ndiye chitsimikizo chofunikira kwambiri kuti chipinda chikhale choyera kuti pakhale ukhondo wofunikira pa kapangidwe kake. Zipangizo za fyulutayo zidzakhudzanso kufanana kwa munda woyendetsera madzi. Pamene fyuluta yosalala kapena mbale yoyendetsera madzi yawonjezeredwa ku fyuluta yoyendetsera madzi, munda woyendetsera madziwo ukhoza kupangidwa mosavuta kukhala wofanana.
2. Mphamvu ya mawonekedwe a liwiro ndi ukhondo wosiyana
Mu chipinda choyera chomwecho, pakati pa malo ogwirira ntchito ndi malo osagwira ntchito okhala ndi kayendedwe kowongoka, chifukwa cha kusiyana kwa liwiro la mpweya pa bokosi la hepa, mphamvu yosakanikirana ya vortex idzachitika pamalo olumikizirana, ndipo malo olumikiziranawa adzakhala malo ozungulira mpweya. Mphamvu ya kugwedezeka kwa mpweya ndi yamphamvu kwambiri, ndipo tinthu tating'onoting'ono tingatumizidwe pamwamba pa makina ogwiritsira ntchito ndikuipitsa zida ndi ma wafer.
3. Zotsatira pa antchito ndi zida
Ngati chipinda choyera chilibe kanthu, makhalidwe a mpweya m'chipinda nthawi zambiri amakwaniritsa zofunikira pa kapangidwe kake. Zipangizo zikalowa m'chipinda choyera, anthu amasuntha, ndipo zinthu zimanyamulidwa, pamakhala zopinga zosapeweka pa kayendetsedwe ka mpweya, monga malo akuthwa otuluka pamakina a zida. Pamakona kapena m'mphepete, mpweyawo umasinthasintha kuti upange malo oyenda osokonezeka, ndipo madzi omwe ali m'deralo sadzanyamulidwa mosavuta ndi mpweya wobwera, zomwe zimapangitsa kuti pakhale kuipitsa.
Nthawi yomweyo, pamwamba pa zida zamakina padzakhala kutentha chifukwa chogwira ntchito mosalekeza, ndipo kutentha kwa mpweya kudzapangitsa kuti malo ozungulira madzi abwererenso pafupi ndi makinawo, zomwe zimapangitsa kuti tinthu tating'onoting'ono tibwererenso m'malo ozungulira madzi. Nthawi yomweyo, kutentha kwakukulu kudzapangitsa kuti tinthu tating'onoting'ono tituluke mosavuta. Zotsatira ziwirizi zimapangitsa kuti gawo lonse loyima likhale lolimba. Kuvuta kuwongolera ukhondo wa mitsinje. Fumbi lochokera kwa ogwiritsa ntchito m'chipinda choyera limatha kumamatira mosavuta ku ma wafer m'malo ozungulira madzi awa.
4. Mphamvu ya pansi yobwerera mpweya
Ngati kukana kwa mpweya wobwerera womwe umadutsa pansi kuli kosiyana, kusiyana kwa kuthamanga kudzachitika, zomwe zimapangitsa kuti mpweya uziyenda molunjika pang'ono, ndipo mpweya wofanana sungapezeke. Njira yodziwika bwino yopangira pano ndikugwiritsa ntchito pansi wokwezeka. Pamene chiŵerengero chotsegulira pansi wokwezeka chili pa 10%, liwiro la mpweya likhoza kugawidwa mofanana pamtunda wa ntchito yamkati. Kuphatikiza apo, chisamaliro chachikulu chiyenera kuperekedwa ku ntchito yoyeretsa kuti muchepetse gwero la kuipitsa pansi.
5. Chochitika choyambitsa
Chomwe chimatchedwa kuti induction phenomenon chimatanthauza chochitika chopanga mpweya woyenda mosiyana ndi kuyenda kofanana, zomwe zimapangitsa fumbi lopangidwa m'chipinda kapena fumbi m'malo oyandikana ndi omwe ali ndi kachilombo kumbali ya mphepo, zomwe zimapangitsa fumbi kuipitsa wafer. Zochitika zomwe zingachitike ndi izi:
(1) Mbale yobisika
Mu chipinda choyera chokhala ndi madzi oyenda mbali imodzi, chifukwa cha malo olumikizirana pakhoma, nthawi zambiri pamakhala mapanelo akuluakulu osawoneka bwino omwe angapangitse madzi kuyenda movutikira komanso kutuluka kwa madzi m'malo mwake.
(2) Nyali
Zowunikira m'chipinda choyera zidzakhala ndi mphamvu zambiri. Popeza kutentha kwa nyali ya fluorescent kumapangitsa kuti mpweya upite patsogolo, nyali ya fluorescent sidzakhala malo osokonezeka. Nthawi zambiri, nyali m'chipinda choyera zimapangidwa ngati madontho a misozi kuti zichepetse mphamvu ya nyali pa kayendedwe ka mpweya.
(3) Mipata pakati pa makoma
Ngati pali mipata pakati pa makoma kapena denga logawanika lomwe lili ndi zofunikira zosiyanasiyana zaukhondo, fumbi lochokera kumadera omwe alibe zofunikira zochepa zaukhondo likhoza kusamutsidwira kumadera oyandikana nawo omwe ali ndi zofunikira zambiri zaukhondo.
(4) Mtunda pakati pa zida zamakina ndi pansi kapena khoma
Ngati mpata pakati pa zida zamakina ndi pansi kapena khoma ndi wochepa, kugwedezeka kwa rebound kudzachitika. Chifukwa chake, siyani mpata pakati pa zida ndi khoma ndikukweza nsanja ya makina kuti musakhudze pansi mwachindunji.
