Microchannel Ubushyuhe bwo Guhindura (MCHEs): Hindura CRensens ya CRAC kubikorwa bya Data Centre

Kubigo byamakuru, ibyuma bya mudasobwa Icyumba cya mudasobwa (CRAC) bikora - cyangwa - gucamo kugirango ukomeze imikorere ya seriveri no kugabanya PUE (Gukoresha ingufu). Umuyoboro gakondo - guhanahana ubushyuhe akenshi bigabanuka - ni binini, bidakora neza, kandi - kubungabunga. InjiraMicrochannel Ubushyuhe bwo Guhindura (MCHEs): ikozwe numuyoboro wa microscale (0.1-2 mm), ihuriweho na - imiterere ya aluminium, hamwe na vacuum brazing, MCHEs ikemura izi ngingo zububabare mugihe zitanga agaciro kagaragara kubikorwa byikigo. Hasi nuburyo bahagaze, wongeyeho ibicuruzwa byabigenewe byerekana ingaruka zabo.

Ibyiza byo Gusaba Ibyiza: Gukemura Data Ikigo Cyinshi Cyububabare

MCHE ntabwo "itezimbere" gusa kuri kondereseri gakondo - basobanura neza ibishoboka kubigo byamakuru byibanda kubikorwa, umwanya, ikiguzi, no kwizerwa.

1. 30 - 50% Ubushyuhe bwo Kwimura Hejuru=PUE yo hepfo

Ibigo byamakuru birwanira kugumana PUE munsi ya 1.3 - kandi MCHEs nintwaro y'ibanga. Imiyoboro yabo ya microscale irema ubuso bunini bwihariye (200-350 m² / m³, 2–3x ya moderi ya - moderi ya fin), guhatira firigo (nka R134a cyangwa R410A) mumazi akomeye (Reynolds numero Re> 2300). Ibi bigabanya ubukana bwumuriro, bigasunika coefficente yubushyuhe kuri 400-600 W / (m² · K) (vs . 200 - 300 W / (m² · K) kuri tube-fin).

Icyo ibi bivuze kuri wewe: Kuburemere bwa kilowati 100, MCHEs yagabanije ubushyuhe bwa dogere 3-5. Buri gipimo cya dogere 1 kigabanya gukoresha compressor ikoreshwa na 2-33%, bivuze kuri 25-35% yo gukoresha ingufu za CRAC. Ku kigo cya m² 1000 giciriritse, ni 30.000-42.000 kWh mu kuzigama amashanyarazi buri mwaka - na PUE yavuye kuri 1.4 igera munsi ya 1.25.

Byuzuye kuri: Hejuru - amakuru yububiko (ubucucike bwimbaraga> 300 W / m²) cyangwa guhindura ibice bishaje bya CRAC (nta mpamvu yo kwagura umwanya kugirango wongere ubukonje).

2. 30 - 50% Ntoya, 40-60% Umucyo: Bika Ikibanza Cyagaciro Data Data Umwanya

Umwanya wa data center hasi uhenze - kandi umuyoboro gakondo - kondenseri ya fin. MCHEs 'byose - aluminiyumu - tube + igizwe na fin igishushanyo mbonera gikuraho umuringa munini wumuringa hamwe nu cyuho cya fin cyuzuza imiyoboro - fin moderi.

Kumuyaga 100 kW - gukonjesha:

Umubumbe: MCHEs ifata ~ 0.8 m³ (vs . 1.2 - 1,3 m³ ya tube - fin), ihuza byoroshye kuruhande cyangwa impande.

Uburemere: Kuri ~ 80 kg (vs . 150 kg kuri tube - fin), MCHEs nibyiza kubice bya CRAC hejuru yinzu - bigabanya imitwaro yo kubaka kandi bigabanya amafaranga yo kwishyiriraho (nta bikoresho biremereye bikenewe).

3. 50 - 70% Firigo Ntoya: Gabanya ibiciro & Wuzuze amategeko y’ibidukikije

Firigo nka R410A zihenze kandi ziragenzurwa (dukesha Umuryango w’ubumwe bw’ibihugu by’Uburayi F - Amabwiriza ya gazi n’UbushinwaIcyatsi na Hasi - Isuzuma rya Carbone Isuzuma ryamakuru). Umuyoboro muto wa MCHEs (1/3–1 / 2 uwo muyoboro - fin) ugabanya ubukonje bwa firigo:

Sisitemu ya kilowati 100 ukoresheje R410A ikenera kg 2,5-3,5 za firigo (vs . 8 - kg 10 kuri tube - fin) - kuzigama ~ 300–390 CNY kuri buri gice imbere.

Ingingo nkeya (40% munsi ya tube - fin, tubikesha imitwe ihuriweho) bivuze ingaruka nke z’ibidukikije kandi nta firigo ihenze - hejuru.

4. Kurwanya Ruswa & 10,000-Isaha MTBF: Komeza CRACs ikora 24/7

Ibigo byamakuru bikora bidahagarara - kandi igihe cyo hasi ni catastrophique. Imiyoboro gakondo - kondenseri ya fin yananiwe hakiri kare kubera umuringa - kwangirika kwa aluminium galvanic, ariko MCHEs zubatswe kuramba:

Imiterere idafite aho ihuriye: Gukata Vacuum bikuraho "umuringa - icyuho cya aluminium" (imbarutso ikomeye ya ruswa).

Kwambika ibicuruzwa: Epoxy cyangwa polytetrafluoroethylene (20-50 mm z'ubugari) byongera imbaraga zo gutera umunyu kuva kumasaha 500 kugeza kumasaha arenga 1500.

Igisubizo? MTBF (Hagati yigihe hagati yo kunanirwa) ikubita amasaha 10,000 - hafi kabiri yikubye - fin (amasaha 5.000.000). Kubungabunga bike=igihe gito cyo kubika amakuru yawe.

Guhindura Tekinike Yumukino: Kora MCHEs Gukora CRAC yawe

MCHEs ntabwo "igitonyanga - muri" gusimbuza - bakeneye tweaks kugirango bahuze CRACs idasanzwe. Dore uko tubatezimbere kubigo byamakuru:

1. Igishushanyo mbonera cyubwenge bwo guhindagurika & Urusaku ruto

Multi - kunyura: Seriveri yikoreza spike kumanywa kandi ikamanuka nijoro. MCHEs ikoresha imiyoboro ya 2-4 ibice, ihujwe na elegitoronike yo kwagura ibikoresho, kugirango ihindure firigo: ubushobozi bwuzuye kumpinga, ubushobozi bwigice cyo gutuza. Ibi birinda "hasi - umutwaro udahagije" wibasiye gakondo - pass kondenseri.

Utuje: Data center ikenera urusaku ruri munsi cyangwa rungana na 60 dB (A). MCHEs ikoresha - ikibuga cyoroheje (intera iri hagati ya mm 1.8-22.2) hamwe nabafana ba - umuyaga wo mu kirere (1.5-22.0 m / s)

2. (Kurinda no Kurinda Kurinda): Yubatswe kuri Data Centre Ibidukikije

Umukungugu, umwotsi wa batiri ya UPS, hamwe no gupima amazi ni ibyago byikigo cya data - MCHEs zibakemura umutwe - kuri:

Dual - layer anti - gutwika: Chromate passivation (5-10 μ mm) yongerera imbaraga, mugihe epoxy yo hejuru (20-30 mm) ihagarika itangazamakuru ryangirika. Ibizamini byerekana ko irwanya ingese mu myaka irenga 8 mu bigo byamakuru.

Amazi - gukosora kuruhande (kumazi - CRACs ikonje): Imiyoboro ya MCHE (1-2 mm) ikunda gupima - nuko twongeraho:

100-mesh idafite ibyuma byinjira muyungurura kugirango umutego wanduye.

Imiyoboro ikoreshwa (1 mm inlet → 1.5 mm isohoka) kugirango igabanye umuvuduko - umuvuduko utera igipimo.

Ibiryo - ibipimo byerekana urugero (urugero, aside polyikarubike) kugirango yongere igihe cyogusukura kugeza kumezi 12 (vs . 6 amezi ya tube - fin).

3. Kwishyira hamwe kwa CRAC nta kinyabupfura: Nta myanda, nta kumeneka

MCHEs ikora neza iyo ihujwe na sisitemu ya CRAC - duhindura buri kintu cyose:

Guhuza abafana: Udusimba twa MCHE dufite 15-20% birwanya ikirere munsi ya tube - fin. Dukoresha hasi - static - abafana b'igitutu (50-80 Pa) n'umuvuduko wa capi munsi ya cyangwa munsi ya 1400 rpm kugirango tubike ingufu tutitanze gukonja.

Kureka - Imigaragarire: Imitwe ihuriweho hamwe igabanya intera ibarwa kuva 8-12 (tube - fin) kugeza 2–4. Kabiri - kashe ya ferrule ikomeza kumeneka Bitarenze cyangwa bingana na 1 × 10⁻⁹ Pa · m³ / s (kuri test ya helium yamenetse) - ingenzi kumutekano wa firigo.

Impamvu MCHEs ari ejo hazaza ha CRAC

Kubigo byamakuru, MCHEs ntabwo aribyiza byo guhinduranya ubushyuhe - nuburyo bwo gutsinda intego zirambye, kugabanya ibiciro, no gukomeza seriveri ikora neza. Waba wubaka ikigo kinini - cyangwa kuzamura CRACs zishaje, MCHEs zitanga imikorere, kuzigama umwanya, hamwe nigihe kirekire ukeneye kugirango uhangane.

Witeguye guhindura kondenseri yawe ya CRAC? Shakisha uburyo MCHEs ishobora kugabanya PUE yawe no kuzamura imikorere yikigo cyawe uyumunsi.
