Mwero wekubuda kwezvipenyu muindasitiri yekugadzira yeIC wakabatana zvakanyanya nehukuru nehuwandu hwezvipenyu zvemhepo zvakaiswa pachip. Sangano rakanaka rekufambisa mhepo rinogona kubvisa zvipenyu zvinogadzirwa neguruva kubva mukamuri rakachena kuti rive nechokwadi chekuti imba yakachena yakachena, kureva kuti, sangano rekufambisa mhepo mukamuri rakachena rinoita basa rakakosha muhuwandu hwekubuda kweIC. Dhizaini yesangano rekufambisa mhepo mukamuri rakachena inofanirwa kuzadzisa zvinangwa zvinotevera: kuderedza kana kubvisa eddy current mumunda wekuyerera kudzivirira kuchengetwa kwezvipenyu zvinokuvadza; kuchengetedza positive pressure gradient yakakodzera kudzivirira kusvibiswa kwemarudzi akasiyana.
Simba remhepo
Zvichienderana nemutemo wekuchenesa imba, masimba anoshanda pazvikamu anosanganisira simba guru, simba remamorekuru, kukwezvana pakati pezvimedu, simba rekufamba kwemhepo, nezvimwewo.
Simba remhepo: rinoreva simba remhepo inokonzerwa nekutumira, kudzosa mweya, kuyerera kwemhepo inopisa, kusanganisa kwekugadzira, uye mamwe mafungu emhepo ane mwero wakati wekufamba kwemhepo kuti anotakura zvidimbu. Kuti pave nekudzora kwehunyanzvi kwenzvimbo yakachena yemukamuri, simba remhepo ndiyo chinhu chakakosha.
Ongororo dzakaratidza kuti mukufamba kwemhepo, zvidimbu zvinotevera kufamba kwemhepo nekumhanya kwakafanana. Mamiriro ezvidimbu zviri mumhepo anotsanangurwa nekupararira kwemhepo. Kufamba kwemhepo kunokanganisa zvidimbu zvemukati kunonyanya kusanganisira: kufamba kwemhepo (kusanganisira kufamba kwemhepo kwekutanga uye kufamba kwemweya wechipiri), kufamba kwemhepo uye kutenderera kwemhepo kunokonzerwa nevanhu vanofamba, uye kufamba kwemhepo kunokonzerwa nekushanda kwemaitiro nemidziyo yeindasitiri. Nzira dzakasiyana dzekupa mweya, nzvimbo dzekumhanya, vashandisi nemidziyo yeindasitiri, uye zviitiko zvinokonzereswa mumakamuri akachena zvese zvinhu zvinokanganisa mwero wekuchena.
Zvinhu zvinokanganisa kurongeka kwemafambiro emhepo
1. Simba renzira yekugovera mweya
(1). Kumhanya kwemhepo
Kuti mhepo ifambe zvakanaka, kumhanya kwemhepo kunofanira kunge kwakafanana muimba yakachena isina divi rimwe chete; nzvimbo isina mweya inofanira kunge iri diki; uye kuderera kwedzvinyiriro muULPA kunofanirawo kunge kwakafanana.
Kumhanya kwemhepo kwakafanana: ndiko kuti, kusaenzana kwemhepo kunodzorwa mukati me ±20%.
Nzvimbo isina simba pamusoro pemhepo: nzvimbo yeULPA frame haingofanirwe kuderedzwa chete, asi chinonyanya kukosha, modular FFU inofanira kushandiswa kuti furemu isingashande ive nyore.
Kuti mweya upinde wakamira wakananga kumwe chete, kusarudzwa kwekudonha kwesimba refirita kwakakoshawo, zvichireva kuti kurasikirwa kwesimba mufirita hakugone kuchinja.
(2). Kuenzanisa pakati peFFU system ne axial flow fan system
FFU inzvimbo yekupa mweya ine feni nefirita (ULPA). Mushure mekunge mhepo yapinda nefeni yeFFU inonzi centrifugal, dynamic pressure inoshandurwa kuita static pressure mumhepo duct uye inoburitswa zvakaenzana neULPA. Kumanikidzwa kwemhepo iri padenga kunenge kuri negative pressure, zvekuti hapana guruva rinopinda mukamuri rakachena kana firita yatsiviwa. Ongororo dzakaratidza kuti FFU system iri nani pane axial flow fan system maererano nekufanana kwemhepo, air flow parallelism uye ventilation efficiency index. Izvi zvinodaro nekuti air flow parallelism yeFFU system iri nani. Kushandiswa kweFFU system kunogona kuita kuti air flow iri mukamuri rakachena irongeke zviri nani.
(3). Simba rechimiro cheFFU pachayo
FFU inonyanya kuumbwa nemafeni, mafirita, zvishandiso zvinotungamirira kufamba kwemhepo nezvimwe zvinhu. Sefa yeULPA inoshanda zvakanyanya ndiyo vimbiso inonyanya kukosha yekuti imba yakachena inogona kuwana kuchena kunodiwa kwedhizaini. Zvinhu zviri musefa zvinokanganisawo kufanana kwenzvimbo yekuyerera kwemvura. Kana chinhu chakakora chesefa kana ndiro yekuyerera yelaminar yakawedzerwa panzvimbo yekubuditsa sefa, nzvimbo yekubuditsa mvura inogona kugadzirwa zvakaenzana zviri nyore.
2. Mhedzisiro yemhando dzakasiyana dzema "speed interfaces" ekuchena
Mukamuri rimwe chete rakachena, pakati penzvimbo yekushandira nenzvimbo isingashande yekuyerera kwemhepo yakatwasuka, nekuda kwekusiyana kwekumhanya kwemhepo panzvimbo inobuda mhepo yeULPA, mhepo inoputika inobuda panzvimbo iyi, uye nzvimbo iyi ichava nzvimbo inoyerera mhepo ine mhepo ine simba guru rekutenderera kwemhepo. Zvidimbu zvinogona kutapurirwa pamusoro pemidziyo uye zvinosvibisa michina nemawafers.
3. Mhedzisiro yevashandi nemidziyo
Kana imba yakachena isina chinhu, hunhu hwemhepo iri mukamuri hunowanzo sangana nezvinodiwa zvemagadzirirwo. Kana michina yapinda mukamuri yakachena, vashandi vanofamba uye zvigadzirwa zvatumirwa, pachava nezvipingamupinyi pakurongeka kwemhepo. Semuenzaniso, pamakona akabudikira kana kumicheto yemidziyo, gasi rinotsauswa kuti riite nzvimbo ine mhepo inovhuvhuta, uye mvura iri mudunhu iri haitakurwi nyore nyore negasi, zvichikonzera kusvibiswa. Panguva imwe chete, pamusoro pemidziyo pachapisa nekuda kwekushanda nguva dzose, uye tembiricha inokwira ichaita kuti nzvimbo inoyerera zvakare pedyo nemuchina, izvo zvichawedzera kuunganidzwa kwezvidimbu munzvimbo inoyerera zvakare. Panguva imwe chete, tembiricha yakakwira ichaita kuti zvidimbu zvibude zviri nyore. Mhedzisiro miviri iyi inowedzera kuoma kwekudzora kuchena kwese kwese kwe vertical laminar. Guruva rinobva kune vanoshanda mukamuri yakachena riri nyore kwazvo kunamira kuma wafer munzvimbo idzi dzinoyerera zvakare.
4. Simba repasi remhepo inodzoka
Kana simba remhepo inodzoka inopfuura nepasi rakasiyana, musiyano wekumanikidzwa uchagadzirwa, kuitira kuti mhepo ifambe nenzira isina simba, uye mweya wakafanana hauzowanikwe. Nzira yakakurumbira yekugadzira parizvino ndeyekushandisa pasi rakakwirira. Kana simba rekuvhura pasi rakakwirira riri 10%, kumhanya kwemhepo pakukwirira kwekushanda kwekamuri kunogona kugoverwa zvakaenzana. Pamusoro pezvo, kutarisisa kwakanyanya kunofanirwa kupihwa pabasa rekuchenesa kuderedza kusvibiswa kwepasi.
5. Chiitiko cheInduction
Chinonzi chiitiko che induction chinoreva chiitiko chekuti mhepo inoyerera nenzira yakatarisana nekuyerera kwakafanana inogadzirwa, uye guruva rinogadzirwa mukamuri kana guruva riri munzvimbo ine tsvina riri pedyo rinokonzereswa kudivi rinokwira mhepo, kuitira kuti guruva rigone kusvibisa chip. Izvi zvinotevera ndizvo zvinogona kuitika:
(1). Ndiro yekuvhara maziso
Mukamuri rakachena rine kuyerera kwakatwasuka kwakanangana nedivi rimwe chete, nekuda kwemajoini ari pamadziro, kazhinji kune ma blind plates makuru anokonzera kuvhiringika mukuyerera kwemvura munzvimbo iyoyo.
(2). Marambi
Marambi ari mukamuri rakachena achanyanya kukuvadza. Sezvo kupisa kwemarambi efluorescent kuchikonzera kuti mhepo ifambe, hapana nzvimbo inovhuvhuta pasi pemarambi efluorescent. Kazhinji, marambi ari mukamuri rakachena akagadzirwa nechimiro chemisodzi kuti aderedze kukanganiswa kwemarambi pakurongeka kwemhepo.
(3.) Makomba ari pakati pemadziro
Kana paine mipata pakati pezvikamu zvine mwero wakasiyana wekuchena kana pakati pezvikamu nedenga, guruva rinobva munzvimbo ine zvinodiwa zvishoma zvekuchena rinogona kutamisirwa kunzvimbo iri pedyo nezvinodiwa zvakanyanya zvekuchena.
(4). Kureba pakati pemuchina nepasi kana madziro
Kana mukaha uri pakati pemuchina nepasi kana madziro uri mudiki kwazvo, unokonzera kudzokororwa kwemhepo. Saka, siya mukaha uri pakati pemidziyo nemadziro wosimudza muchina kuti usabvumira muchina kubata pasi zvakananga.
