Iyo chip goho mwero muIC indasitiri yekugadzira yakanyatso hukama nehukuru uye huwandu hwemhepo zvimedu zvakaiswa pane chip. Sangano rakanaka rekufambisa kwemhepo rinogona kutora zvimedu zvinogadzirwa neguruva kubva mukamuri yakachena kuti ive nechokwadi chekuchena kwekamuri yakachena, kureva, sangano rekufambisa kwemhepo muimba yakachena inoita basa rinokosha muhuwandu hwezvibereko zvekugadzirwa kweIC. Dhizaini yesangano rekuyerera kwemhepo mukamuri yakachena inoda kuzadzisa zvinangwa zvinotevera: kuderedza kana kubvisa eddy ikozvino munharaunda yekuyerera kudzivirira kuchengetwa kwezvikamu zvinokuvadza; chengetedza yakakodzera kudzvanywa kwakanaka kudzivirira kusvibiswa kwemuchinjikwa.
Simba rekuyerera kwemhepo
Zvinoenderana neiyo yakachena kamuri musimboti, mauto ari kushanda pane zvimedu anosanganisira simba guru, simba remamorekuru, kukwezva pakati pezvimedu, simba rekuyerera kwemhepo, nezvimwe.
Simba rekuyerera kwemhepo: inoreva simba rekufambisa kwemhepo kunokonzerwa nekuunza, kudzoka kwemhepo, kupisa kwemhepo kutenderera kwemhepo, kufambisa kwekugadzira, uye kumwe kuyerera kwemhepo kune imwe nhanho yekuyerera kutakura zvimedu. Kune iyo tekinoroji yekudzora yenzvimbo yakachena yekamuri, simba rekuyerera kwemhepo ndicho chinhu chakakosha.
Ongororo dzakaratidza kuti mukufamba kwemhepo, zvimedu zvinotevera mafambiro emhepo pamwe nekumhanya kwakafanana. Mamiriro ezvimedu zviri mumhepo zvinotariswa nekugoverwa kwemhepo. Mafambiro emhepo anobata mukati memukati anonyanya kusanganisira: mhepo inopa mhepo (kusanganisira yekutanga mhepo uye yechipiri mhepo), kubuda kwemhepo uye thermal convection airflow inokonzerwa nevanhu vanofamba, uye kubuda kwemhepo kunokonzerwa nekushanda kwemaitiro uye zvigadzirwa zvemaindasitiri. Nzira dzakasiyana dzekupa mhepo, nzvimbo dzekumhanya, vashandisi uye zvishandiso zvemaindasitiri, uye zviitiko zvinokonzeresa mumakamuri akachena zvinhu zvese zvinokanganisa hutsanana.
Zvinhu zvinokanganisa kufambiswa kwemhepo
1. Kufurirwa kwenzira yekupa mweya
(1). Kumhanya kwemhepo
Kuti uve nechokwadi chekuyerera kwemhepo, mhepo yekufambisa mhepo inofanira kunge yakafanana mukamuri isina unidirectional yakachena; nzvimbo yakafa yemhepo inopa nzvimbo inofanira kuva duku; uye kudonha kwekumanikidza muULPA kunofanirawo kunge kwakafanana.
Uniform air supply speed: kureva, kusaenzana kwemhepo kunodzorwa mukati me ± 20%.
Ishoma nzvimbo yakafa pamhepo yekugovera pamusoro: kwete chete iyo nzvimbo yendege yeULPA furemu inofanira kuderedzwa, asi zvinonyanya kukosha, modular FFU inofanira kutorwa kuti kurerutsa iyo yakareruka furemu.
Kuve nechokwadi chekumira unidirectional kuyerera kwemhepo, kudonhedza kudonhedza kusarudzwa kwesefa kwakakoshawo, zvinoda kuti kurasikirwa kwekumanikidza musefa hakugone kutsauka.
(2). Kuenzanisa pakati peFFU system uye axial kuyerera fan system
FFU inzvimbo yekupa mweya ine feni uye sefa (ULPA). Mushure mekunge mhepo yasvetwa mukati neiyo centrifugal fan yeFFU, iyo ine simba dzvinyiriro inoshandurwa kuita static pressure mumhepo duct uye inopeperetswa kunze zvakafanana neULPA. Mhepo yekupa simba padenga ndeyekumanikidza kwakashata, kuitira kuti pasave neguruva rinopinda mukamuri rakachena kana sefa inotsiviwa. Ongororo dzakaratidza kuti iyo FFU system yepamusoro kune axial kuyerera fan system maererano nemhepo yekubuda yakafanana, airflow parallelism uye kufefetedza kunyatsoshanda index. Izvi zvinodaro nekuti kuyerera kwemhepo kufanana kweFFU system kuri nani. Kushandiswa kweFFU system kunogona kuita kuti mhepo ifambe muimba yakachena yakarongeka.
(3). Pesvedzero yeFFU pachayo chimiro
FFU inonyanya kuumbwa nemafeni, mafirita, madhiraivha ekufambisa kwemhepo uye zvimwe zvinhu. Iyo yekupedzisira-yepamusoro-inoshanda sefa ULPA ndiyo inonyanya kukosha vimbiso yekuti imba yakachena inogona kuwana kuchena kunodiwa kwedhizaini. Izvo zvinhu zvesefa zvichakanganisawo kufanana kwenzvimbo inoyerera. Kana iyo coarse sefa zvinhu kana laminar inoyerera ndiro yakawedzerwa kune yekusefa, iyo yekubuda inoyerera munda inogona kugadzirwa nyore yunifomu.
2. Mhedzisiro yeakasiyana masipidhi anosanganisirwa ehutsanana
Muimba imwechete yakachena, pakati penzvimbo yekushanda uye isiri-yekushanda ye vertical unidirectional kuyerera, nekuda kwekusiyana kwemhepo inomhanya paULPA outlet, yakasanganiswa vortex effect ichagadzirwa pane iyo interface, uye iyi interface ichava mhirizhonga yekuyerera kwemhepo ine kunyanya kukwira kwemhepo. Zvimedu zvinogona kuendeswa pamusoro pemidziyo uye kusvibisa midziyo uye mawafer.
3. Mhedzisiro yevashandi nemidziyo
Kana imba yakachena isina chinhu, maitiro ekuyerera kwemhepo mukamuri anowanzo kusangana nezvinodiwa zvekugadzira. Kana iyo michina ichipinda mukamuri rakachena, vashandi vanofamba uye zvigadzirwa zvinofambiswa, pachava nezvipingamupinyi kusangano rekuyerera kwemhepo. Semuyenzaniso, pamakona anobuda kana kumacheto emidziyo, gasi rinozotsauswa kuita nzvimbo ine mhirizhonga, uye mvura iri munzvimbo yacho haitakurwe nyore nyore negasi, zvichikonzera kusvibiswa. Panguva imwecheteyo, pamusoro pemidziyo ichapisa nekuda kwekuenderera mberi kwekushanda, uye tembiricha yekushisa inokonzeresa nzvimbo yekuyerera padyo nemuchina, izvo zvinozowedzera kuunganidzwa kwezvikamu munzvimbo yekuyerera. Panguva imwecheteyo, kupisa kwepamusoro kuchaita nyore nyore kuti zvikamu zvipukunyuke. Iwo maviri maitiro anowedzera kuoma kwekudzora iyo yakazara vertical laminar kuchena. Iyo huruva kubva kune vanoshanda mukamuri yakachena iri nyore kwazvo kuomerera kune mawaferi munzvimbo idzi dzekuyerera.
4. Kufurira kwekudzoka kwemhepo pasi
Apo kushorwa kwemhepo yekudzoka inopfuura nepasi kwakasiyana, mutsauko wekumanikidzika uchagadzirwa, kuitira kuti mhepo inoyerera munzira yekushomeka kushoma, uye yunifomu yemhepo haizowaniki. Iyo yazvino yakakurumbira dhizaini nzira ndeye kushandisa yakakwira pasi. Kana chiyero chekuvhura chepasi chakakwirira chiri 10%, mhepo yekuyerera kwemhepo muhurefu hwekushanda hwekamuri inogona kugoverwa zvakaenzana. Pamusoro pezvo, kunyatsotarisisa kunofanirwa kubhadharwa kubasa rekuchenesa kuderedza kusvibiswa kwepasi.
5. Induction phenomenon
Iyo inonzi induction phenomenon inoreva chiitiko chekuti kuyerera kwemhepo kune yakatarisana nekuyerera kweunifomu kunogadzirwa, uye guruva rinogadzirwa mukamuri kana guruva riri munzvimbo yakatarisana yakasvibiswa inokwidziridzwa kudivi remhepo, kuitira kuti guruva rinogona kusvibisa chip. Izvi zvinotevera zvinogona kuitika induction phenomena:
(1). Bofu ndiro
Mukamuri yakachena ine vertical unidirectional kuyerera, nekuda kwemajoini ari pamadziro, pane kazhinji mahombe mapofu mahwendefa ayo anoburitsa mhirizhonga mukuyerera kwenzvimbo yekudzoka.
(2). Mwenje
Zvigadziriso zvemwenje muimba yakachena zvichava nemigumisiro yakakura. Sezvo kupisa kwemarambi efluorescent kunokonzera kubhururuka kwemhepo, hakuzovi nenzvimbo ine mhirizhonga pasi pemarambi efluorescent. Kazhinji, marambi ari mukamuri rakachena akagadzirwa muchimiro chemisodzi kuti kuderedze kukanganiswa kwemarambi pamusangano wekuyerera kwemhepo.
(3.) Mipata pakati pemadziro
Kana paine mikaha pakati pezvikamu zvine mwero wakasiyana wehutsanana kana pakati pezvikamu uye sirin'i, guruva rinobva munzvimbo ine hutsanana hunodiwa hunogona kutamirwa kune yakatarisana nenzvimbo ine yakanyanya kuchena zvinodiwa.
(4). Distance pakati muchina uye pasi kana madziro
Kana gaka riri pakati pemuchina nepasi kana madziro riri diki kwazvo, zvinokonzeresa rebound mhirizhonga. Naizvozvo, siya mukaha pakati pemidziyo nemadziro uye simudza muchina kuti usarega muchina uchibata pasi zvakananga.
