Microchannel coils (MCHES) dilanni taabolo .

MCHES dilanni ye tigitigi ye-Baarakɛcogo min bɛ fɛnw dɔnniya, fɛnɲɛnamafagalanw bɔli, ani funteni ɲɔgɔndan fɛɛrɛw fara ɲɔgɔn kan, minnu dabɔra ka Ultra-Flow siraw (0,1–2 mm) dilan walasa ka funteni jiginni kɛ ka ɲɛ. Fɛn minnu ye nin ye, olu ye nin ye:

1. Aluminiyɔmu bɔgɔlan labɛnni .

MCHEw bɛ baara kɛ fɔlɔ ni aluminiyɔmu sɔgɔlenw ye (misali la, 3003, 6061) k’a sababu kɛ u ka nɔgɔn, u ka funteni jiginni ka bon, ani u musaka-Nɔgɔya.

Material Selection .: High-Aluminiyɔmu saniyalenw bɛ ɲagami ni fɛnw ye minnu bɛ kɛ ka fɛnw sɔgɔ (magnesium, silicon) walasa ka masinw fanga ni u sɔgɔli kunbɛn, ka ASTM B209 walima EN 573-3 sariyaw dafa.

Preprocessing .: Ingot surfaces bɛ degrease (ka baara kɛ ni alkaline cleaners ye) ani ka mɔ (ni asidi azote dilute) walasa ka ɔkisizɛni, tulu, walima nɔgɔw bɔ-Kritiki walasa ka bɔli ni brazing quality kɛ cogo kelen na kɔfɛ.

2. Microchannel flat tube extrusion .

O sen in bɛ Kɛ MCHES "core" ye: tubabukan fla minnu bɛ ni mikro-kansɛri caman ye.

Setup extrusion .: Aluminiyɔmu bɔgɔlama min bɛ funteni sɔrɔ (450–500℃) o bɛ gɛrɛntɛ ka tɛmɛ tigitigi-Engineered die (ni microchannel-Shaped cavities) ye hydraulique press fɛ. Die design bɛ kanal hakɛ dantigɛ ka ɲɛsin (a ka c’a la .<1 mm for high-efficiency models) and distribution.

Taille calibration .: Tubu fla min bɛ bɔ kɛnɛ kan, o bɛ nɛnɛ teliya la (fiɲɛ walima ji bancogo fɛ) walasa ka a hakɛ sabatili sabati, o kɔ aw bɛ a tigɛ ka se a janya ma min ka kan (ka bɔ mɛtɛrɛ 0,5 la ka se mɛtɛrɛ 6 ma, ka kɛɲɛ ni a kɛli ye).

Quality Check .: Laser mikromɛtiriw bɛ kanal cɛmancɛ, kogo janya, ani flakɛli sɛgɛsɛgɛ-tolerances bɛ kɔlɔsi ±0,02 mm kɔnɔ walasa ka se ka jibɔ kunbɛncogo bɛnbaliya bali.

3. Fins Stamping & Forming .

Finw bɛ fara tubabukan fla kan walasa ka funteni jiginni yɔrɔ bonya (o ye fɛnba ye MCHE baarakɛcogo ɲuman na).

Stamping baarakɛcogo .: Aluminiyɔmu sɛbɛnw (0,1–0,2 mm janya) bɛ balo ni timbre precision ye walasa ka fin patterns dilan-Common designs include louvered fins (for enhanced fiɲɛbɔ turbulence) walima fins corrugated (for compactness).

Pre-Furakɛcogo kura .: finw bɛ se ka kɛ yɔrɔ furakɛli la (misali la, chromate conversion coating) walasa ka nɔrɔli ɲɛ ka ɲɛ ni brazing flux ye ani ka post-Brazing Corrosion resistance bonya.

4. Core Assembly (Tube-Fin stacking) .

Tubabu fla ni finw bɛ lajɛ ka kɛ "suma-yɔrɔ-yɔrɔ-koro"-Basikɛ-yɔrɔ-ko-yɔrɔ ye.

Layered stacking .: Tubabu fla bɛ ɲɔgɔn sɔrɔ ɲɔgɔn fɛ, ni finw bɛ don tubabu kɛrɛfɛ ka kɛ sandwich-i n’a fɔ fɛn ye. Waati dɔɔnin sirilanw bɛ lajɛyɔrɔ minɛ a nɔ na walasa ka ɲɔgɔndanbaliya bali.

gap control .: Tubabu ni finw cɛ danfara bɛ mara .<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Vacuum brazing (thermal joining) .

Vacuum brazing ye fɛɛrɛ kɔrɔlen ye min bɛ tubabukan fla ni finw siri kudayi ka kɛ bɔgɔ ye-Koro min bɛ se ka kɛ ni laadala solder ye, o bɛ kɛ sababu ye ka jɔli fanga bonya ani ka funteni jiginni sabati.

Flux application .: Aluminiyɔmu-Silicon (Al-Si) brazing flux (melting point ~577℃) bɛ fiyɛ walima ka su ji la min lajɛlen don walasa ka oksidan bali funteni waati.

Vacuum Furnace baarakɛcogo .: Koori bɛ bila foro kɔnɔ min bɛ kɛ ni vacuum ye (Tressure .<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.

nɛnɛ .: Foro in bɛ nɛnɛ dɔɔni dɔɔni (dɛrɛ 50–100 /lɛrɛ) walasa ka funteni degun dɔgɔya, ka mikrokarasiw bali mikrokan na.

6. Tigɛ & Port Machining .

O brazed core bɛ baara kɛ walasa ka ɲɔgɔndan ports fara a kan ji don/bɔ.

Core tigɛ .: CNC Saw bɛ a kɔnɔna tigɛ ka se a laban hakɛ ma (misali la, 300×400 mm ka ɲɛsin jagokɛlaw ka konfirɛzi MCHES ma), ni nɛnɛmadalan bɛ kɛ ka funteni bali{4}}Dɔnniyali min bɛ sɔrɔ.

port drilling & tapping .: Tubabu fla dakunw bɛ sɔgɔ ka kɛ manifold ports ye, o kɔ, u bɛ tap ka jiriw fara ɲɔgɔn kan (misali la, M10 walima 1/4 NPT) walasa ka nɛnɛmadafɛlanw siri ɲɔgɔn na. Deburring tools bɛ nɛgɛ sɔgɔlenw bɔ walasa ka kanali balili bali.

7. Degun sɛgɛsɛgɛli & bɔgɔbɔli dɔnni .

MCHES bɛ bɔgɔji gɛlɛn de wajibiya-tightness (a kɔrɔlen don nɛnɛmadalan kama-A bɛ baara kɛ ni baarakɛminɛnw ye minnu sinsinnen bɛ i n’a fɔ AC walima frigo).

Degun sɛgɛsɛgɛli .: 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 bɛ a jira ko a bɛ bɔ.
