MicroChannel Heat Exchangers (MCHES): Transform CRAC Condensers okusobola okukola obulungi mu data center .

Ku data centers, computer room air conditioner (CRAC) condensers zikola-oba-okukutula okukuuma omulimu gwa seeva n’okukka PUE (obulungi bw’okukozesa amaanyi). Tube ey'ennono-ebiwanyisiganya ebbugumu ebiwedde bitera okugwa mu bumpimpi-binene, tebikola bulungi, era bya waggulu-maintenance. OkuyingiraEbintu ebikyusa ebbugumu mu microchannel (MCHES) .: Engineered ne microscale flow channels (0.1–2 mm), enzimba ya aluminiyamu yonna -egatta, n’okuwunyiriza, MCHEs zigonjoola ensonga zino ez’obulumi ate nga zituusa omuwendo ogulabika ku mirimu gya data center. Wansi's how they stand out, plus the custom tweaks that maximize their impact.

Core Application Ebirungi: Gonjoola Data Center's Biggest Pain points

MCHE tezikoma ku "kulongoosa" ku kondensa ez'ennono-ziddamu okunnyonnyola ekisoboka ku bifo eby'amawulire ebitunuulidde obulungi, ekifo, omuwendo, n'okwesigamizibwa.

1. 30–50% Obulung’amu bw'okutambuza ebbugumu obusingako=PUE eya wansi .

Data centers zirwana okukuuma PUE wansi wa 1.3-era MCHE kya kyama. Emikutu gyazo egya microscale gikola ekitundu ekinene ennyo eky’okungulu (200–350 m2/m3, 2–3x ekyo ekya tube-fin models), nga kiwaliriza firiigi (nga R134A oba R410A) mu kukulukuta okw’amaanyi okw’obutabanguko (reynolds number re > 2300). Kino kikendeeza ku buziyiza bw’ebbugumu, okusika omugerageranyo gw’okutambuza ebbugumu okutuuka ku 400–600 W/(m2·K) (vs. 200–300 W/(m2·K) ku ttanka-fin).

Kino kye kitegeeza gy’oli: Ku mugugu gw’okunyogoza kwa kW 100, MCHES esala ebbugumu lya kondening ku 3–5℃. Buli kugwa kwa diguli 1 kukendeeza ku nkozesa y’amaanyi ga kompyuta ebitundu 2–3%, okuvvuunula okutuuka ku 25–35% amaanyi ga CRAC aga wansi. Ku 1000 m2 medium data center, ekyo kiri 30,000–42,000 kWh mu kukekkereza amasannyalaze buli mwaka-era PUE yagwa okuva ku 1.4 okutuuka wansi wa 1.25.

Perfect for: high-density data centers (amaanyi density > 300 W/m2) oba okuddamu okuteeka crac units enkadde (tekyetaagisa kugaziya kifo okutumbula okunyogoga).

2. 30–50% Ebitono, 40–60% biweweevu: Kekkereza ekifo eky’omuwendo eky’ekifo kya data .

Data center floor space is costly-era ttanka ey’ennono-Fini condensers eyonoona. mches' zonna-aluminum flat-tube + ensengekera y'ebiwaawaatiro ebiyungiddwa emalawo ebikoona by'ekikomo ebinene n'ebituli by'ebiwujjo ebizimba ttaapu-eby'okufukirira.

Ku mpewo ya kW 100-okuteekawo okunyogoza:

Volume: MCHE zitwala ~0.8 m3 (vs. 1.2–1.3 m3 ku ttanka-fin), okutuuka mu ngeri ennyangu mu njuyi oba mu nsonda.

Obuzito: Ku ~80 kg (vs. 150 kg ku ttanka-Fin), mches zisinga ku kasolya crac units-Zikendeeza ku ssente z’okuzimba n’okusala ku ssente z’okussaako (tewali ggiya ya kusitula muzito eyeetaagibwa).

3. 50–70% less refrigerant: okusala ku nsaasaanya & okutuukiriza amateeka g'obutonde .

Ebiziyiza nga R410A bya bbeeyi era bifugibwa (olw’okulungamya kwa EU-Gas ne China’sGreen ne Low-Okukebera okupima ebipimo bya kaboni ku bifo ebitereka amawulire .). MCHES' tiny channel volume (1/3–1/2 eyo eya tube-FIN) esala ebyetaago by'ekifuuwa amazzi:

Enkola ya kW 100 nga ekozesa R410A yeetaaga kkiro 2.5–3.5 zokka ez’ekiziyiza (VS. 8–10 kg ku ttanka-fin) -okukekkereza ~300–390 CNY buli yuniti mu maaso.

Ebifo ebitono ebivuba (40% ebitono okusinga tube-fin, olw’emitwe egy’okugatta) kitegeeza akabi k’obutonde obutono era tewali waggulu wa ssente nnyingi-UPS.

4. Okuziyiza okukulukuta & 10,000-hour MTBF: Kuuma ebiwonvu nga bikola 24/7.

Data centers zitambula nga teziyimiridde-era downtime ya katyabaga. Tube ey’ennono-ebiwujjo bya fin bigwa nga bukyali olw’ekikomo-aluminum galvanic corrosion, naye MCHE zizimbibwa okuwangaala:

Enzimba etaliimu buzibu: vacuum brazing emalawo "ekikomo-ebituli bya aluminum" (ekiziyiza ekinene eky'okukulukuta).

Ebizigo ebikoleddwa ku mutindo: Epoxy oba polytetrafluoroethylene coatings (20–50 μm thick) booza okufuuyira omunnyo okuva ku ssaawa 500 okutuuka ku ssaawa ezisukka mu 1500.

Ekyavaamu? MTBF (mean time between failures) ekuba essaawa 10,000-kumpi emirundi ebiri ku ya tube-fin (essaawa 5,000–6,000). Okuddaabiriza okutono=Obudde obutono obw'okuyimirira ku kifo kyo eky'amawulire.

Custom Technical Adaptations: kola MCHE okukola ku CRAC yo

MChes si "okugwa-mu" okukyusa-Beetaaga tweaks okukwatagana n'ebyetaago bya CRACs eby'enjawulo. Laba engeri gye tuzirongoosaamu ku data centers:

1. Smart design for load fluctuations & amaloboozi amatono .

Multi-Emikutu gy'okuyita .: Server loads spike emisana n'egwa ekiro. MCHE zikozesa emikutu gy’okutambula kw’ekitundu 2–4, nga gigatta ne vvaalu ezigaziwa ez’amasannyalaze, okutereeza okutambula kwa firiigi: obusobozi obujjuvu obw’entikko, obusobozi obw’ekitundu ku lulls. Kino kyewala "low-load inefficiency" ebonyaabonya ennono emu-okuyita condensers.

ebiwaawaatiro ebisirifu .: Data centers zeetaaga amaloboozi agatawera oba agenkana 60 dB (a). MCHE zikozesa ebiwaawaatiro ebifunda-ebiwaawaatiro ebiwanvu (ebbanga lya mm 1.8–2.2) ne wansi-Ebiwandiiko by’ennyonyi (1.5–2.0 m/s) -okusala amaloboozi nga 3–5 dB (a) vs. tube-FIN, SO (Okuddaabiriza n’okuddaabiriza) ttiimu ezikola nga tezikola.

2. (Obukuumi bw’okuzibikira n’okuzibikira): Yazimbibwa ku mbeera za data center .

Enfuufu, UPS Battery Fumes, ne Water Scaling bya data center-MChEs zikwata ku mutwe-ku:

dual-Layer Anti-Okusiiga okukulukuta .: Chromate passivation (5–10 μm) enyweza okunywerera, ate epoxy waggulu layer (20–30 μm) eziyiza okuvunda emikutu. Ebigezo biraga nti kiziyiza obusagwa okumala emyaka egisukka mu 8 mu data centers.

Amazzi-Okuzibikira oludda (ku mazzi-ebigo ebinyogozeddwa): Emikutu gya MCHE (1–2 mm) gitera okugerageranya-kale twongerako:

100-mesh stainless steel inlet filters okutega obucaafu.

Emikutu egy’enjawulo (1 mm inlet → 1.5 mm outlet) okukendeeza ku kukulukuta-ebipimo ebivaako minzaani.

Emmere-Ebiziyiza minzaani (okugeza, asidi wa polycarboxylic) okugaziya ebiseera by’okuyonja okutuuka ku myezi 12 (VS. 6 emyezi ku ttanka-Fin).

3. Okugatta CRAC okutaliimu buzibu: tewali kasasiro, tewali kukulukuta .

MCHE zikola bulungi nga zigatta n'enkola za CRAC-Tulongoose buli kuyungibwa:

Okukwatagana kw'abawagizi .: MCHE ebiwaawaatiro birina 15–20% resistance y’empewo entono okusinga tube-Fin. Tukozesa ebiwujjo ebya wansi-static-ebinyigiriza (50–80 PA) n’embiro z’enkoba ku wansi oba okwenkana 1400 rpm okukekkereza amaanyi awatali kusaddaaka kunyogoga.

Okuvuba-Ebiyungo ebiziyiza .: Emitwe egy’okugatta egy’okusala ensengekera y’enkolagana okuva ku 8–12 (tube-fin) okutuuka ku 2–4. Double-ebisiba ebiva mu fuleemu bikuuma okukulukuta nga kutono okusinga oba okwenkana 1×10⁻⁹ Pa·m3/s (per helium leak tests) -Ekikulu ku bukuumi bw’okufuumuula.

Lwaki MCHes bye biseera eby'omumaaso ebya Crac Condensers .

Ku data centers, MCHE si kifo kirungi kyokka eky'okuwanyisiganya ebbugumu-Engeri y'okukuba ebiruubirirwa by'okuyimirizaawo, okusala ku nsaasaanya, n'okukuuma seeva nga zikola mu ngeri eyesigika. Oba ozimba ekifo eky'oku ntikko-density oba okulongoosa cracs enkadde, MCHE zituusa obulungi, okukekkereza ekifo, n'okuwangaala olina okusigala ng'ovuganya.

Mwetegefu okukyusa crac condensers zo? Yeekenneenya engeri MCHES gy’esobola okukendeeza ku pue yo n’okutumbula omutindo gwa data center yo leero.
