Cov txheej txheem raug ntawm microchanman coils (mches)

Kev tsim cov mches yog qhov precision - Cov txheej txheem kev tshawb fawb, thiab ua kom cov khoom siv hluav taws xob ntxiv (0.1-2 mm) rau kev hloov tshav kub. Cov kauj ruam tseem ceeb muaj raws li hauv qab no:

1. Txhuas Alloy Alloy Khoom Npaj

Mches feem ntau siv aluminium alloys (piv txwv li, 3003, 6061) vim lawv lub cev hnyav, thiab tus nqi siab- ua hauj lwm zoo.

Cov khoom siv xaiv: High {{- Kev ua suab paj tau sib xyaw nrog cov khoom siv hluav taws xob (magnesium ua rau muaj zog (magnes tsis kam, sib tham aytm bik9 lossis en 573-3 tus qauv.

Preprocessing: Ingot siurfaces yog degreeed (siv alkaline cov tshuaj ntxuav) thiab pickled (nrog diluties {}}}

2. Microchanan Ca raj Rauv Extrusion

Cov kauj ruam no cov qauv "tseem ceeb" ntawm Mches: tiaj tus leeg nrog ntau yam kev sib tw microchannels.

Extrusion Teeb: Ib tug rhuab aluminium alloy billet (450-500 degree) yog thawb los ntawm qhov precision-} duab puab) ntawm cov xovxwm hydraulic. Tus tsim qauv tuag ncaj qha txiav txim ncaj qha channel loj (feem ntau<1 mm for high-efficiency models) and distribution.

Qhov loj me calibration: Lub raj xa khoom tiaj tus raj yog txias sai (ntawm huab cua lossis dej tawm sab nraud) los tswj qhov ntev ntev (los ntawm 0.5 m rau 6 m, nyob ntawm daim ntawv thov).

Xyuas Zoo: Laser micrometers qhia cov kab mob chanch, phab ntsa thickness, thiab flatness {{mm kom tsis txhob ntws tsis tooj tsis muaj kev cuam tshuam.

3. Fins Stamping & Sib Sau

Fins tau ntxiv rau lub tiaj tiaj tus kom nthuav cov tshav kub hloov thaj chaw deb (ib qho tseem ceeb hauv MCHE efficiency).

Cov txheej txheem stamping: Aluminium nplooj ntawv (0.1-0.2 mm tuab) yog pub rau hauv lub ntsej muag fins- Lub cev muaj huab cua (rau kev cog qoob loo dav hlau) lossis ua kom tiav).

Ua ntej -} txheej kev kho: Fins yuav dhau mus rau kev kho mob ntev (piv txwv li, kev hloov pauv cov roj ntsha) txhawm rau txhim kho Adhesion nrog brazing post- brazing corrosion.

4. Cov kev sib dhos tseem ceeb (raj -} fin stacking)

Tiaj tus tubes thiab fins tau sib sau ua ke mus rau hauv "cua sov ua kom sib hloov pauv" {- qhov yooj yim ua haujlwm.

Fawm kib Stacking: Ca cov hlab ntsha yog ua kom sib thooj, nrog fin tso ntawm cov leeg ib sab los ua ib qho sandwich - zoo li qauv. Clamps ib ntus tuav cov sib txoos hauv qhov chaw los tiv thaiv kev ua txhaum cai.

Lub Nkag Kev Tswj Xyuas: Qhov sib txawv ntawm cov hlab thiab fins khaws cia ntawm<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Lub tshuab nqus tsev (thermal koom nrog)

Lub tshuab nqus pas yog cov kauj ruam tseem ceeb uas ruaj khov rau hauv cov hlab ntsha thiab cov kab ke tsis zoo li qub

Flux Daim Ntawv Thov: Ib txheej nyias ntawm aluminium - silicon (al-

Lub Tshuab Cua Sov Rauv: Cov tub ntxhais tau muab tso rau hauv lub tshuab nqus tsev hluav taws xob (siab<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.

Cua txias: Lub cub tawg yog txias qeeb (50-100℃/ teev) kom txo cov thermal kev ntxhov siab, tiv thaiv microcacks hauv cov microchhannels.

6. TEJ TXIAV & ECTING MACHINAY

Lub tub ntxhais kab core yog cov txheej txheem ntxiv kom ntxiv cov chaw sib txuas rau kua hauv inlet / qhov rai.

Lub hauv paus tej: Lub cnc pom txiav cov tub ntxhais mus rau qhov kawg khoom loj (piv txwv li × 400 × 400 × 400- indication deformation.

Chaw nres nkoj Drilling & Tapping: Qhov xaus ntawm lub tiaj tiaj tus yog drilled los tsim cov vacts manifold, ces muab rau ntxiv xov (piv txwv li, m10 lossis 1/4 NPT) rau txuas cov kab tub yees. Cov cuab yeej deburring tshem tawm cov shavings hlau los tiv thaiv cov kev thaiv cov channel.

7. Kev Kuaj Siab & Kev Tshawb Fawb

MCHES require require-} nrawm nroos (tseem ceeb rau tub yees-} kev siv thiab cov tub yees).

Siab xeem: 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 qhia tias muaj dej xau.

Helium so kom pom: Rau siab - precision appss (piv txwv li, Helium Mass Spectrometry yog siv los tshawb txog micro {} × 10-3 â ·.

8. Nto Kho & Anti -} corrosion txheej (yeem)

Rau mches siv nyob rau hauv cov chaw hnyav (piv txwv li, marine lossis siab- av noo chaw), ntxiv kev tiv thaiv kev tiv thaiv kev txhim kho yog siv:

Daim Ntawv Thov Txheej Txheej: Phenico poloxy, epoxy, lossis fluoropolymer txheej yog txau los yog electrophoresed mus rau qhov chaw tseem ceeb. Cov txheej txheej txheej tuab yog tswj hwm ntawm 20-50 μm kom muaj kev cuam tshuam corrosion tsis kam thiab tshav kub hloov efficiency.

Kev kho: Cov txheej txheem coated yog ci ntawm 120-180℃rau 30-60 feeb los kho cov txheej, sib sau ua ib txheej.

9. Kev Soj Ntsuam Zoo Tshaj & Ntim

Kev Ntsuas Xyuas: Cov kws tshuaj ntsuam xyuas qhov ntev (ntawm kev sib txuas lus ntsuas cov khoom sib txuas lossis cov kev ntsuas kub hloov chaw (siv cua sov Random

Ntim: Tsim nyog MCHES tau qhwv rau hauv noo noo {{}} Cov ntaub ntawv ua yeeb yaj kiab thiab ntim cov khoom ua kom tiv thaiv kev puas tsuaj thaum thauj mus los.

Tus txheej txheem no ua kom zoo mchees ua ntej kev ua tau nruj ua ntej, thiab hvac tshuab sib npaug, kev sib raug zoo, thiab kev ntseeg tau.

Hylita yog nruab nrog kev siv tshuab ntau lawm thiab sib dhos, ua kom muaj kev siv tsheb ntau heev rau cov kab helated helated helated helated helated helated antated kab.
