Mlingo wa zokolola za chip mumakampani opanga IC umagwirizana kwambiri ndi kukula ndi kuchuluka kwa tinthu tating'ono ta mpweya toyikidwa pa chip. Bungwe loyendetsa mpweya wabwino limatha kutenga tinthu tating'onoting'ono tomwe timapanga fumbi kuchoka m'chipinda choyera kuti zitsimikizire ukhondo wa chipinda choyera, ndiko kuti, bungwe loyendetsa mpweya mu chipinda choyera limagwira ntchito yofunika kwambiri pakupanga IC. Mapangidwe a bungwe loyendetsa mpweya m'chipinda choyera amayenera kukwaniritsa zolinga zotsatirazi: kuchepetsa kapena kuthetsa eddy panopa m'munda wothamanga kuti mupewe kusungidwa kwa tinthu toipa; sungani mayendedwe oyenera kuti mupewe kuipitsidwa.
Mphamvu ya Airflow
Malinga ndi mfundo yachipinda choyera, mphamvu zomwe zimagwira pazigawozi zikuphatikiza mphamvu yayikulu, mphamvu ya mamolekyulu, kukopa pakati pa tinthu tating'onoting'ono, mphamvu yakuyenda kwa mpweya, ndi zina zambiri.
Mphamvu ya Airflow: imatanthawuza mphamvu ya mpweya yomwe imabwera chifukwa cha kubweretsa, kubwereranso kwa mpweya, kutuluka kwa mpweya wotentha, kusonkhezera kochita kupanga, ndi maulendo ena a mpweya omwe ali ndi kuthamanga kwina kunyamula tinthu ting'onoting'ono. Pakuwongolera kwaukadaulo kwa malo achipinda choyera, mphamvu yoyendera mpweya ndiye chinthu chofunikira kwambiri.
Mayesero asonyeza kuti mu kayendedwe ka mpweya, tinthu tating'onoting'ono timatsatira kayendedwe ka mpweya pafupifupi liwiro lomwelo. Mkhalidwe wa tinthu ting'onoting'ono ta mpweya umatsimikiziridwa ndi kugawa kwa mpweya. Kuthamanga kwa mpweya komwe kumakhudza tinthu tating'onoting'ono ta m'nyumba makamaka kumaphatikizapo: mpweya wotulutsa mpweya (kuphatikizapo mpweya woyambira ndi mpweya wachiwiri), mpweya wa mpweya ndi kutentha kwa mpweya wa convection chifukwa cha kuyenda kwa anthu, ndi kutuluka kwa mpweya chifukwa cha ntchito ndi mafakitale. Njira zosiyanasiyana zoperekera mpweya, malo olumikizirana liwiro, ogwira ntchito ndi zida zamafakitale, ndi zochitika zochititsa chidwi m'zipinda zoyera ndizinthu zomwe zimakhudza ukhondo.
Zinthu zomwe zimakhudza kayendetsedwe ka ndege
1. Mphamvu ya njira yoperekera mpweya
(1). Kuthamanga kwa mpweya
Kuonetsetsa kuti mpweya ukuyenda bwino, liwiro la mpweya liyenera kukhala lofanana mu chipinda choyera cha unidirectional; gawo lakufa la mpweya woperekera mpweya liyenera kukhala laling'ono; ndipo kutsika kwamphamvu kwa ULPA kuyeneranso kukhala kofanana.
Kuthamanga kwa mpweya wofanana: ndiko kuti, kusagwirizana kwa mpweya kumayendetsedwa mkati mwa ± 20%.
Malo ochepera akufa pamtunda woperekera mpweya: osati malo a ndege a ULPA akuyenera kuchepetsedwa, koma chofunikira kwambiri, modular FFU iyenera kutengedwa kuti muchepetse mawonekedwe osafunikira.
Kuonetsetsa kuti mpweya woyimirira unidirectional ukuyenda, kusankha kotsitsa kwa fyuluta ndikofunikira kwambiri, kumafuna kuti kutayika kwamphamvu mu fyuluta sikungapatuke.
(2). Kuyerekeza pakati pa FFU system ndi axial flow fan fan
FFU ndi gawo loperekera mpweya wokhala ndi fani ndi fyuluta (ULPA). Mpweya ukayamwidwa ndi centrifugal fan ya FFU, kukakamiza kosunthika kumasinthidwa kukhala static pressure mu duct ya mpweya ndikuwulutsidwa mofanana ndi ULPA. Kuthamanga kwa mpweya padenga ndi kuthamanga koipa, kotero kuti palibe fumbi lomwe lidzalowe m'chipinda choyera pamene fyulutayo yasinthidwa. Kuyesera kwawonetsa kuti dongosolo la FFU ndilapamwamba kuposa mawonekedwe a axial flow fan potengera kutulutsa kwa mpweya, kufanana kwa mpweya komanso kuwongolera mpweya wabwino. Izi ndichifukwa choti kufanana kwa mpweya wa FFU ndikwabwinoko. Kugwiritsa ntchito kachitidwe ka FFU kumatha kupangitsa kuti mpweya uziyenda bwino mchipinda choyera.
(3). Chikoka cha mawonekedwe a FFU omwe
FFU imapangidwa makamaka ndi mafani, zosefera, zida zowongolera mpweya ndi zina. Chosefera chapamwamba kwambiri cha ULPA ndiye chitsimikiziro chofunikira kwambiri ngati chipinda choyera chingakwaniritse ukhondo wofunikira pamapangidwewo. Zinthu za fyuluta zidzakhudzanso kufanana kwa malo othamanga. Pamene zosefera zowoneka bwino kapena mbale yoyenda ya laminar iwonjezeredwa ku zosefera, gawo lotuluka limatha kupanga yunifolomu mosavuta.
2. Kukhudzidwa kwa liwiro losiyanasiyana laukhondo
M'chipinda choyera chomwecho, pakati pa malo ogwirira ntchito ndi malo osagwira ntchito omwe amatuluka pamtunda wa unidirectional, chifukwa cha kusiyana kwa liwiro la mpweya pamtunda wa ULPA, phokoso losakanikirana lidzapangidwa pa mawonekedwe, ndipo mawonekedwewa adzakhala malo ozungulira mpweya wothamanga kwambiri kwambiri. Tinthu tating'onoting'ono titha kufalikira pamwamba pa zida ndikuipitsa zida ndi zowotcha.
3. Zotsatira za ogwira ntchito ndi zida
Chipinda chaukhondo chikakhala chopanda kanthu, mawonekedwe a mpweya m'chipindamo nthawi zambiri amakwaniritsa zofunikira zamapangidwe. Zida zikalowa m'chipinda choyera, kusuntha kwa ogwira ntchito ndikufalitsidwa, mosakayikira padzakhala zopinga ku bungwe loyendetsa mpweya. Mwachitsanzo, pamakona otuluka kapena m'mphepete mwa zida, gasiyo amapatutsidwa kuti apange malo osokonekera, ndipo madzi omwe ali m'derali satengeka mosavuta ndi mpweya, motero amawononga. Panthawi imodzimodziyo, pamwamba pa zidazo zidzawotcha chifukwa cha ntchito yopitirira, ndipo kutentha kwa kutentha kumayambitsa malo ozungulira pafupi ndi makina, zomwe zidzawonjezera kusonkhanitsa kwa tinthu tating'onoting'ono mu reflow zone. Panthawi imodzimodziyo, kutentha kwakukulu kumapangitsa kuti particles zichoke mosavuta. Zotsatira zapawiri zimakulitsa zovuta zowongolera ukhondo wonse woyima wa laminar. Fumbi lochokera kwa ogwira ntchito m'chipinda choyera ndi losavuta kumamatira ku zowomba m'magawo awa.
4. Chikoka cha mpweya wobwerera pansi
Pamene kukana kwa mpweya wobwerera kupyola pansi kumakhala kosiyana, kusiyana kwapakati kudzapangidwa, kotero kuti mpweya uziyenda motsatira njira yochepetsera kukana, ndipo mpweya wofanana sungapezeke. Njira yamakono yamakono ndiyo kugwiritsa ntchito malo okwera. Pamene kutsegulira kwa malo okwera ndi 10%, kuthamanga kwa mpweya pamtunda wogwirira ntchito wa chipindacho kumatha kugawidwa mofanana. Komanso, chidwi kwambiri ayenera kulipira ntchito yoyeretsa kuchepetsa kuipitsidwa gwero la pansi.
5. Chochitika chodzidzimutsa
Zomwe zimatchedwa induction phenomenon zimatanthawuza chodabwitsa kuti mpweya wopita kumbali yosiyana ndi kutuluka kwa yunifolomu umapangidwa, ndipo fumbi lopangidwa m'chipindamo kapena fumbi lomwe lili pafupi ndi malo oipitsidwa limapangidwira kumbali ya mphepo, kotero kuti fumbi likhoza kuwononga chip. Zotsatirazi ndi zomwe zotheka induction phenomena:
(1). Mbale wakhungu
M'chipinda choyera chokhala ndi vertical unidirectional flow, chifukwa cha zolumikizira pakhoma, nthawi zambiri pamakhala mbale zazikulu zakhungu zomwe zingapangitse chipwirikiti pakubwerera kwanuko.
(2). Nyali
Zowunikira m'chipinda choyera zidzakhudza kwambiri. Popeza kutentha kwa nyali za fulorosenti kumapangitsa kuti mpweya uzikwera, sipadzakhala malo osokonezeka pansi pa nyali za fulorosenti. Nthawi zambiri, nyali za m'chipinda choyera zimapangidwira mu mawonekedwe a misozi kuti achepetse mphamvu ya nyali pa bungwe la airflow.
(3.) Mipata pakati pa makoma
Pakakhala mipata pakati pa magawo omwe ali ndi ukhondo wosiyanasiyana kapena pakati pa magawo ndi denga, fumbi lochokera m'dera lomwe lili ndi zofunikira zaukhondo likhoza kusamutsidwa kumalo oyandikana nawo omwe ali ndi zofunikira zaukhondo.
(4). Mtunda pakati pa makina ndi pansi kapena khoma
Ngati kusiyana pakati pa makina ndi pansi kapena khoma ndi kochepa kwambiri, kumayambitsa chipwirikiti. Choncho, siyani kusiyana pakati pa zipangizo ndi khoma ndikukweza makina kuti musalole kuti makinawo agwire pansi mwachindunji.
