Proses bilong wokim ol Koil (MCHE)

Prodaksen bilong ol MCHE em i wanpela proses i stret-}riven we i bungim ol samting bilong saiens, ekstrusen molding, na ol teknoloji i joinim thermal, i stret long kamapim ol ultra-smol flo senel (0.1–2 mm) bilong gutpela hat trensfe. Ol ki step em olsem:

1. Preperesen blong Aluminium Alloy Materiol .

Ol MCHE i save yusim ol aluminium aloi (olsem, 3003, 6061) bikos long lait, bikpela thermal konduktiviti bilong ol, na kos-efektiviti.

Meteriel Seleksen: Ol hai-}ol aluminium ingot i save miksim wantaim ol samting i stap insait (magnesium, silikon) bilong strongim strong bilong masin na strong bilong daunim korosen, na bungim ASTM B209 o EN 573-3 standet.

Priproses: Ol ingot pes i save lus (yusim alkaline klina) na pik (wantaim liklik naitrik asit) long rausim ol oksait, oil, o ol pipia-ritikal bilong lukim olsem yunifom ekstrusen na brazing kwaliti bihain.

2. Mikrosenel Flet Tube Ekstrusen

Dispela step i kamapim "kor" bilong ol MCHE: ol flet tiub i gat planti paralel maikrosenel.

Setup bilong Ekstrusen: Wanpela aluminium aloi billet (450–500 digri ) i save pusim i go insait long wanpela stretpela dai-}ijinia dai (wantaim maikrosenel{{i}}sep hul) long rot bilong wanpela haidrolik pres. Disain bilong dai i makim stret sais bilong senel (planti taim<1 mm for high-efficiency models) and distribution.

Sais Kalibresen: Flet tiub we oli extrudem i kam kolkol kwiktaem (tru long ea o wota we i stap kam nogud) blong mentenem dimensenol stebiliti, afta oli katem i go long longfala we oli nidim (stat long 0.5 m kasem 6 m, i dipen long aplikesen).

Kwaliti Jek: Ol laser maikromita i verifaiim senel diamita, wol tiknes, na flatnes-}ol tolerans i kontrolim insait long ±0.02 mm long abrusim ron resistens i no stret.

3. Ol Fin Stamping & Fomim

Ol i save putim ol fin long ol flet tiub bilong skruim ples bilong senisim hat bilong en (em wanpela bikpela samting long MCHE efisiensi).

Proses bilong stem: Ol aluminium pepa (0.1–0.2 mm tik) oli fidim olgeta i go long wan presis steming pres blong krietem ol fin paten-}ol komon disaen i inkludim ol fin we oli louver (blong mekem eaflo i kam antap moa) o ol fin we oli korogetem (blong kompaktem).

Pre-}Keting Tritmen: Ol fain i ken kisim tritmen bilong pes (olsem, kromet konvesen koting) long kamapim gutpela pas wantaim brazing fluks na strongim post-i brazing korosen resistens.

4. Asembli (Tub-}Fin Staking)

Ol flat tiub na fin i save bungim i go insait long wanpela "hat eksenja kor"- besik fanksenel yunit.

Staking we i stap long Lea: Ol flat tiub oli laenap long paralel, wetem ol fin we oli putum bitwin ol tiub we oli stap kolosap blong mekem wan sanwij- olsem strakja we i olsem. Ol klem blong smol taem oli holem asembli i stap blong blokem misalign.

Kontrol bilong Gap: Gap namel long ol paip na fin i stap long<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Vakum Brazing (Thermal Joining)

Vakum brazing em i bikpela step we i save pasim ol flet tiub na fin oltaim i go insait long wanpela lik-'tait kor-} i no wankain olsem tumbuna soldering, em i mekim bikpela straksa strong na thermal konduktiviti.

Fluks Aplikesen: Wanpela liklik hap bilong aluminium-silikon (Al-Si) brazing fluks (melting poin ~577 digri ) i spreim o dipim i go long asemblied kor bilong stopim oksidesen long taim bilong hatim.

Prosesing blong ol Furnesing blong Vakum: Ol i putim as bilong en insait long wanpela 'vacum furnace' (presa<10⁻³ Pa) and heated to 580–620°C. At this temperature, the flux melts and flows along the tube-fin interfaces, while the aluminum base material remains solid. The vacuum environment eliminates air bubbles, ensuring uniform brazing.

Kolim: Ol i save mekim paia i kol isi isi (50–100 digri /aua) bilong daunim hevi bilong hat, na dispela i save pasim ol liklik samting long ol liklik samting long ol maikrosenel.

6. Katim & Port Masining

Ol i prosesim brazed kor bilong putim ol koneksen port bilong wara inlet/autlet.

As bilong Katim: Wanpela CNC i lukim i katim as bilong fainel prodak sais (olsem, 300×400 mm bilong ol komesel frisa MCHE), wantaim kolsan ol i yusim long abrusim hat- indusim difomesen.

Port drilim & Tepim: Ol i drilim ol arere bilong ol flet tiub bilong kamapim ol port bilong manifold, bihain ol i paitim bilong putim ol tret (olsem, M10 o 1/4 NPT) bilong konektim ol lain bilong friji. Ol tul we oli no strong tumas oli karemaot ol aean seving blong blokem ol rod blong blokem.

7. Presa Testing & Lik Diteksen

Ol MCHE i nidim strongpela lik-}taitnes (kritikal bilong frigerant- beis aplikesen olsem AC o friji).

Tes bilong Pressure: The core is filled with high-pressure nitrogen (1.5–2 times the design working pressure, typically 2–3 MPa) and held for 30–60 minutes. Pressure gauges monitor for drops-any loss >0.01 MPa i soim lik.

Helium Lik Diteksen: Long ol hai-}ol presisen aplikesen (olsem, otomotiv AC), ol i yusim helium mas spektrometri long painim maikro-lik (sensitiviti i go daun long 1×10 " Pa·m3/s).

8. Tritmen bilong pes na Anti{1}}}Korrosen Koting (Opsenel)

Long ol MCHE ol i yusim long ol hatpela ples (olsem, ol seting bilong solwara o hai-}hamiditi), ol i yusim moa korosen proteksen:

Aplikesen bilong Koting: Ol i save spreim o elektrofores long resin, epoksi, o fluoropolymer koting i go antap long as bilong en. Tiknes bilong kotim ol i save kontrolim long 20–50 μm bilong balensim korosen resistens na hat trensfer efisiensi.

Kirapim: Ol i kukim dispela 'coroted core' long 120-180 digri inap long 30-60 minit bilong oraitim kot, na dispela i kamapim wanpela strongpela, i no inap long karim.

9. Faenol Kwaliti Inspeksen & Pakejing

Testing we yu save traem blong traem: Ol inspekta i sekim ol dimensen (long rot bilong kodinet masin bilong mesarim), (long brazim ol bagarap olsem ol krek o fluks residu), na mekim ol random hat trensfer efisiens tes (yusim wanpela win tanel long skelim hat eksens reit aninit long standet kondisen).

Pakejing: Ol MCHE we oli kwalifae oli rabem long wetwet-poof film mo oli pakem long fom-}laen katon blong blokem damej long taem blong transpot.

Dispela proses i mekim na ol MCHE i inapim ol strongpela pefomens rikwaemen bilong ol aplikesen olsem komesel friji, otomotiv ea kondisen, na HVAC sistem-lansing efisiens, kompaktnes, na reliabiliti.
