Microchannel Heat Exchangers (MCHEs): Shandura CRAC Condensers yeData Center Kubudirira

Panzvimbo dzedata, macondenser eComputer Room Air Conditioner (CRAC) anogadzirwa-kana-kutyora kuitira kuchengetedza kushanda kwesevha uye kudzikisa PUE (Kushanda Kwesimba). Traditional chubhu-fin heat exchanger inowanzotadza-yakakura, haishande, uye-inogadzirisa zvakanyanya. EnterMicrochannel Heat Exchangers (MCHEs): yakagadzirwa ne microscale flow channels (0.1–2 mm), yakasanganiswa yese-aluminum structure, uye vacuum brazing, MCHEs inogadzirisa marwadzo aya apo ichiendesa kukosha kunobatika kwe data center operations. Pazasi ndiwo maitiro avanoita kunze, pamwe netsika tweaks dzinowedzera maitiro avo.

Core Application Advantages: Gadzirisa Data Center's Biggest Pain Points

MaMCHE haango "natsurudza" pamakondurudzo echinyakare-anotsanangura patsva izvo zvinogoneka kunzvimbo dzedata dzakanangana nekuita basa, nzvimbo, mutengo, uye kuvimbika.

1. 30–50% Kufambiswa Kwekupisa Kwepamusoro=Kudzika PUE

Nzvimbo dzedata dzinorwira kuchengetedza PUE iri pasi pe1.3-uye MCHE chombo chakavanzika. Matanho avo madiki anogadzira nzvimbo yakakura chaiyo (200–350 m²/m³, 2–3x iyo yechubhu-mamodheru emufin), achimanikidza mafiriji (seR134a kana R410A) kuti aite mhirizhonga yakasimba (Reynolds nhamba Re > 2300). Izvi zvinodzikisira kudzikisira, zvichisundidzira kuchinjisa kupisa kusvika ku400–600 W/(m²·K) (vs. 200–300 W/(m²·K) yechubhu-fin).

Izvi zvinorevei kwauri: Pamutoro unotonhora we100 kW, maMCHE anocheka tembiricha inodzika ne3-5 degrees. Kudonha kwega kwega kwe1 kunoderedza kushandiswa kwesimba recompressor ne2-3%, zvichiturikira ku25-35% yakaderera CRAC simba rekushandisa. Kune 1000 m² yepakati data centre, iyo 30,000–42,000 kWh mukuchengetedza magetsi pagore-uye PUE yakadzikira kubva pa1.4 kuenda pasi pe1.25.

Yakakwana ye: High-density data centers (simba density > 300 W/m²) kana kudzorera mayunitsi eCRAC ekare (hapana chikonzero chekuwedzera nzvimbo kuti iwedzere kutonhora).

2. 30–50% Diki, 40–60% Yakareruka: Chengetedza Valuable Data Center Space

Data center floor space inodhura-uye zvechinyakare chubhu{1}}fin condensers inoiparadza. MCHEs' all-aluminum flat-tube + integrated fin design inobvisa kukombama kwemhangura nemagap ayo anovhuvhuta chubhu-fin models.

Kune 100 kW mweya{1}yakatonhodzwa setup:

Vhoriyamu: MCHEs inotora ~0.8 m³ (vs. 1.2–1.3 m³ yechubhu-fin), inokwana zviri nyore mumativi kana makona.

Huremu: Pa ~80 kg (vs. 150 kg yechubhu-fin), MCHEs akanakira mayunitsi eCRAC pamusoro pedenga remba-anoderedza mutoro wekuvaka uye kuderedza mari yekuisa (hapana giya rekusimudza rinorema rinodiwa).

3. 50–70% Zvishoma Mufiriji: Cheka Mari uye Sangana nemitemo yezvakatipoteredza

Mafiriji akaita seR410A anodhura uye anodzorwa (nekuda kweEU's F-Gas Regulation neChina'sGreen uye Yakaderera{{0}Carbon Rating Evaluation yeData Centers). MCHEs 'diki chiteshi vhoriyamu (1/3–1/2 iya yechubhu-fin) inocheka zvinodiwa mufiriji:

A 100 kW system inoshandisa R410A inongoda 2.5–3.5 kg yefiriji (vs. 8–10 kg yechubhu-fin)-saving ~300–390 CNY per unit kumusoro.

Mapoinzi mashoma ekubvinza (40% yakaderera pane chubhu-fin, tinotenda kune misoro yakasanganiswa) zvinoreva kushomeka kwenjodzi yezvakatipoteredza uye hapana mafiriji anodhura-kumusoro.

4. Corrosion Resistance & 10,000-Hour MTBF: Chengetedza CRACs Achimhanya 24/7

Nzvimbo dzedata dzinomhanya nguva dzese-uye nguva yekudzikira injodzi. Traditional chubhu-fin condensers inotadza kukasika nekuda kwecopper-aluminum galvanic corrosion, asi MCHEs anovakwa kuti agare:

Chimiro chisina musono: Vacuum brazing inobvisa "mhangura-magapu ealuminium" (chinhu chikuru chinokonzeresa ngura).

Tsika machira: Epoxy kana polytetrafluoroethylene coatings (20-50 μm gobvu) inosimudzira munyu kupfapfaidza kuramba kubva pa500 maawa kusvika anopfuura 1500 maawa.

Zvakaguma nei? MTBF (Mean Time Between Failures) inorova maawa 10,000-inoda kupeta zvakapetwa kaviri echubhu-fin (5,000–6,000 hours). Kugadzirisa kushoma=kushoma nguva yekudzikira panzvimbo yako yedata.

Tsika dzeTekinoroji Adapta: Ita MCHEs Ishandire CRAC Yako

MCHEs haisi "kudonhedza-mukati" kutsiva-inoda kugadziriswa kuti ienderane nezvinodiwa neCRACs. Heano maitiro atinoita optimize nzvimbo dzedata:

1. Yakangwara Dhizaini Yekutakurwa Kuchinja & Kuderera Noise

Zviteshi{{0}zvakawanda: Server inotakura spike masikati uye inodonha husiku. MCHEs anoshandisa 2-4 chikamu chekuyerera nzira, akabatanidzwa nemagetsi ekuwedzera mavharuvhu, kugadzirisa refrigerant kuyerera: yakazara huwandu hwepamusoro, chidimbu chiyero che lulls. Izvi zvinodzivirira "kuderera-kutadza kushanda zvakanaka" uko kunotambudza echinyakare{{5}pase condenser.

zvimbi zvinyararire: Nzvimbo dzedata dzinoda ruzha Zvishoma pane kana kuenzana ne60 dB (A). MaMCHE anoshandisa zvimbi zvakatetepa-zvakaremerwa zvimbi (1.8–2.2 mm spacing) uye zvakaderera-mafeni ekuyerera kwemhepo (1.5–2.0 m/s){8}}zvinocheka ruzha ne3–5 dB (A) maringe nechubhu-zvipenyu, saka (kushanda nekugadzirisa) zvikwata zvinoshanda zvisina kukanganiswa.

2. (Corrosion & Clogging Protection): Yakagadzirirwa Data Center Environments

Hupfu, utsi hwebhatiri reUPS, uye kuwedzera kwemvura injodzi pakati pedata{0}}MCHEs inozvigadzirisa nemusoro-pa:

Dual-layer anti{1}}corrosion coating: Chromate passivation (5-10 μm) inowedzera kunamatira, nepo epoxy yepamusoro layer (20-30 μm) ichivharira corrosive media. Miedzo inoratidza kuti inoramba ngura kweanopfuura makore 8 munzvimbo dzedata.

Mvura-inogadzirisa kuvharika (yemvura-yakatonhorera maCRAC): MCHE machaniro (1–2 mm) anokasika kukura-saka tinowedzera:

100-mesh Stainless simbi inlet mafirita kuteya tsvina.

Tapered channels (1 mm inlet → 1.5 mm outlet) kuderedza kuyerera-reti maspikes anokonzera sikero.

Food-grade scale inhibitors (eg, polycarboxylic acid) kuwedzera nguva dzekuchenesa kusvika kumwedzi gumi nemiviri (vs. 6 mwedzi yechubhu-fin).

3. Seamless CRAC Kubatanidzwa: Hapana Kurasa, Hapana Kubuda

MCHEs inoshanda zvakanyanya kana yapetwa neCRAC masisitimu{{0}isu tinokwenenzvera kubatanidza kwese:

Fani kuenzanisa: MCHE zvimbi zvine 15–20% yakaderera mhepo yekudzivirira pane chubhu-fin. Isu tinoshandisa yakaderera-static-pressure fans (50–80 Pa) uye cap speed iri Pass than kana kuenzana ne1400 rpm kuchengetedza simba pasina kurega kutonhora.

Inobvinza{{0}makomba ekuona: Misoro yakabatanidzwa inocheka kuverenga kubva pa8-12 (tube-fin) kusvika pa2–4. Kaviri-ferrule seals inochengeta kuvuza Zvishoma pane kana kuenzana ne1×10⁻⁹ Pa·m³/s (per helium leak tests)-zvakakosha pakuchengetedza mufiriji.

Nei MCHEs Iro Ramangwana reCRAC Condensers

Kunzvimbo dzedata, MCHEs haingori nani yekutsinhanisa kupisa-inzira yekurova nayo zvibodzwa zvinoenderera mberi, kuderedza mitengo, uye kuita kuti maseva arambe achishanda zvakavimbika. Ungave uri kuvaka-nzvimbo ine density yakakura kana kusimudzira maCRAC ekare, MCHEs inopa kushanda zvakanaka, kuchengetedza nzvimbo, uye kusimba kwaunoda kuti urambe uchikwikwidza.

Wagadzirira kushandura yako CRAC condensers? Ongorora kuti MCHEs inogona kudzikisa sei PUE yako uye kuwedzera mashandiro enzvimbo yako yedata nhasi.
