Kuchuluka kwa mpweya wotuluka mu makampani opanga ma IC kumagwirizana kwambiri ndi kukula ndi kuchuluka kwa tinthu ta mpweya tomwe timayikidwa pa chip. Bungwe labwino loyendetsa mpweya lingathe kuchotsa tinthu ta mpweya tomwe timapangidwa ndi fumbi kuchokera ku chipinda choyera kuti zitsimikizire kuti chipinda choyera chili choyera, kutanthauza kuti, bungwe loyendetsa mpweya m'chipinda choyera limagwira ntchito yofunika kwambiri pa kuchuluka kwa mpweya wotuluka mu IC. Kapangidwe ka bungwe loyendetsa mpweya m'chipinda choyera kayenera kukwaniritsa zolinga izi: kuchepetsa kapena kuchotsa mphamvu ya eddy m'munda woyenda kuti tipewe kusungidwa kwa tinthu toopsa; kusunga mphamvu yoyenera yothamanga kuti tipewe kuipitsidwa.
Mphamvu ya mpweya
Malinga ndi mfundo ya chipinda choyera, mphamvu zomwe zimagwira ntchito pa tinthu timeneti zimaphatikizapo mphamvu yaikulu, mphamvu ya mamolekyulu, kukopana pakati pa tinthu timeneti, mphamvu ya mpweya, ndi zina zotero.
Mphamvu ya mpweya: imatanthauza mphamvu ya mpweya yomwe imabwera chifukwa cha kutumizidwa, kubweza mpweya, kutentha kwa mpweya, kusakaniza kochita kupanga, ndi mpweya wina wokhala ndi liwiro linalake lonyamula tinthu tating'onoting'ono. Pakuwongolera kwaukadaulo kwa malo oyera m'chipinda, mphamvu ya mpweya ndiyo chinthu chofunikira kwambiri.
Kafukufuku wasonyeza kuti mu kayendedwe ka mpweya, tinthu timeneti timatsatira kayendedwe ka mpweya pafupifupi liwiro lomwelo. Mkhalidwe wa tinthu timeneti mumlengalenga umatsimikiziridwa ndi kufalikira kwa mpweya. Mayendedwe a mpweya omwe amakhudza tinthu ta m'nyumba makamaka ndi awa: kuyenda kwa mpweya (kuphatikizapo kuyenda kwa mpweya woyamba ndi kuyenda kwa mpweya wachiwiri), kuyenda kwa mpweya ndi kutentha kwa mpweya komwe kumayambitsidwa ndi anthu oyenda, ndi kuyenda kwa mpweya komwe kumayambitsidwa ndi ntchito yogwirira ntchito ndi zida zamafakitale. Njira zosiyanasiyana zoperekera mpweya, malo olumikizirana liwiro, ogwiritsa ntchito ndi zida zamafakitale, ndi zochitika zomwe zimachitika m'zipinda zoyera zonse ndi zinthu zomwe zimakhudza kuchuluka kwa ukhondo.
Zinthu zomwe zimakhudza kayendetsedwe ka mpweya
1. Mphamvu ya njira yoperekera mpweya
(1). Liwiro la mpweya
Kuti mpweya uyende bwino mofanana, liwiro la mpweya liyenera kukhala lofanana m'chipinda choyera cholunjika mbali imodzi; malo opanda mpweya pamwamba pake ayenera kukhala ochepa; ndipo kutsika kwa mphamvu mu ULPA kuyeneranso kukhala kofanana.
Liwiro la mpweya wofanana: ndiko kuti, kusalingana kwa kayendedwe ka mpweya kumayendetsedwa mkati mwa ± 20%.
Malo ochepa opanda mpweya pamalo operekera mpweya: sikuti malo ozungulira a chimango cha ULPA okha ndi omwe ayenera kuchepetsedwa, komanso chofunika kwambiri, FFU yokhazikika iyenera kugwiritsidwa ntchito kuti chimango chowonjezera chikhale chosavuta.
Kuti muwonetsetse kuti mpweya ukuyenda molunjika mbali imodzi, kusankha kutsika kwa mphamvu ya fyuluta n'kofunika kwambiri, zomwe zimafuna kuti kutayika kwa mphamvu mu fyuluta kusasinthe.
(2). Kuyerekeza pakati pa dongosolo la FFU ndi dongosolo la fan la axial flow
FFU ndi chipangizo choperekera mpweya chokhala ndi fan ndi fyuluta (ULPA). Mpweya ukalowetsedwa ndi fan ya centrifugal ya FFU, mphamvu yamagetsi imasinthidwa kukhala mphamvu yosasunthika mu duct ya mpweya ndikutulutsidwa mofanana ndi ULPA. Kupanikizika kwa mpweya padenga ndi mphamvu yoipa, kotero kuti fumbi silidzalowa m'chipinda choyera fyuluta ikasinthidwa. Mayesero asonyeza kuti dongosolo la FFU ndi lapamwamba kuposa dongosolo la fan ya 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 kungapangitse kuti mpweya upite m'chipinda choyera bwino.
(3). Mphamvu ya kapangidwe ka FFU
FFU imapangidwa makamaka ndi mafani, zosefera, zida zowongolera mpweya ndi zinthu zina. Fyuluta ya ULPA yogwira ntchito bwino kwambiri ndiyo chitsimikizo chofunikira kwambiri chotsimikizira ngati chipinda choyera chingathe kukwaniritsa ukhondo wofunikira wa kapangidwe kake. Zipangizo za fyulutayo zidzakhudzanso kufanana kwa munda woyenda. Pamene fyuluta yolimba kapena mbale yoyenda ya laminar yowonjezeredwa ku fyuluta yotulukira, munda woyendamo ukhoza kupangidwa mosavuta kukhala wofanana.
2. Zotsatira za liwiro losiyanasiyana la ukhondo
Mu chipinda choyera chomwecho, pakati pa malo ogwirira ntchito ndi malo osagwira ntchito omwe ali ndi kayendedwe kowongoka, chifukwa cha kusiyana kwa liwiro la mpweya pamalo otulukira a ULPA, mphamvu yosakanikirana ya vortex idzapangidwa pamalo olumikizirana, ndipo malo olumikiziranawa adzakhala malo ozungulira mpweya okhala ndi mphamvu yayikulu ya mpweya. Tinthu tating'onoting'ono tingatumizidwe pamwamba pa chipangizocho ndikuipitsa zida ndi ma wafer.
3. Zotsatira za ogwira ntchito ndi zida
Chipinda choyera chikakhala chopanda kanthu, makhalidwe a mpweya m'chipindacho nthawi zambiri amakwaniritsa zofunikira pa kapangidwe kake. Zipangizo zikalowa m'chipinda choyera, anthu amasuntha ndipo zinthu zimatumizidwa, padzakhala zopinga pa kayendetsedwe ka mpweya. Mwachitsanzo, pamakona otuluka kapena m'mphepete mwa zidazo, mpweyawo udzasinthidwa kuti upange malo osokonezeka, ndipo madzi omwe ali m'deralo sangatengeke mosavuta ndi mpweyawo, zomwe zimayambitsa kuipitsa. Nthawi yomweyo, pamwamba pa zidazo padzatentha chifukwa chogwira ntchito mosalekeza, ndipo kutentha kwa mpweya kudzayambitsa malo obwerera m'mbuyo pafupi ndi makinawo, zomwe zidzawonjezera kuchuluka kwa tinthu tating'onoting'ono m'dera lobwerera m'mbuyo. Nthawi yomweyo, kutentha kwambiri kudzapangitsa kuti tinthu tating'onoting'ono tituluke mosavuta. Zotsatira ziwirizi zimapangitsa kuti pakhale zovuta kuwongolera ukhondo wonse wa laminar. Fumbi lochokera kwa ogwira ntchito m'chipinda choyera ndi losavuta kutsatira ku ma wafers m'malo obwerera m'mbuyo awa.
4. Mphamvu ya pansi yobwerera mpweya
Ngati kukana kwa mpweya wobwerera womwe umadutsa pansi kuli kosiyana, kusiyana kwa kuthamanga kudzapangidwa, kotero kuti mpweya uziyenda molunjika ku mphamvu yochepa, ndipo mpweya wofanana sungapezeke. Njira yodziwika bwino yopangira pano ndikugwiritsa ntchito pansi mokweza. Pamene mphamvu yotsegulira pansi mokweza ndi 10%, liwiro la mpweya womwe uli pamtunda wogwirira ntchito mchipindamo likhoza kugawidwa mofanana. Kuphatikiza apo, chisamaliro chachikulu chiyenera kuperekedwa ku ntchito yoyeretsa kuti muchepetse kuipitsidwa kwa pansi.
5. Chochitika choyambitsa
Chomwe chimatchedwa induction phenomenon chimatanthauza chodabwitsa chakuti mpweya woyenda mosiyana ndi momwe umayenda mofanana umapangika, ndipo fumbi lopangidwa m'chipindamo kapena fumbi lomwe lili pafupi ndi malo oipitsidwa limayambitsidwa kumbali ya mphepo, kotero kuti fumbi likhoza kuipitsa chip. Zotsatirazi ndi zochitika zomwe zingachitike chifukwa cha induction:
(1). Mbale yobisika
Mu chipinda choyera chokhala ndi kayendedwe kowongoka kolunjika mbali imodzi, chifukwa cha malo olumikizirana pakhoma, nthawi zambiri pamakhala mbale zazikulu zosawoneka bwino zomwe zimapangitsa kuti madzi abwerere m'malo mwake.
(2). Nyali
Zowunikira m'chipinda choyera zidzakhala ndi mphamvu zambiri. Popeza kutentha kwa nyali za fluorescent kumapangitsa kuti mpweya upite patsogolo, sipadzakhala malo osokonezeka pansi pa nyali za fluorescent. Kawirikawiri, 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 magawo okhala ndi ukhondo wosiyanasiyana kapena pakati pa magawo ndi denga, fumbi lochokera m'dera lomwe lili ndi ukhondo wochepa likhoza kusamutsidwira kudera lapafupi lomwe lili ndi ukhondo wochuluka.
(4). Mtunda pakati pa makina ndi pansi kapena khoma
Ngati mpata pakati pa makina ndi pansi kapena khoma ndi wochepa kwambiri, ungayambitse kugwedezeka kwa ma rebound. Chifukwa chake, siyani mpata pakati pa zida ndi khoma ndikukweza makinawo kuti makina asakhudze pansi mwachindunji.
