Mikrokanɛliw (MCHE) ka fɛnw dilan cogo

MCHEw dilanni ye fɛɛrɛ ye min be kɛ ni tiɲɛn ye-driven ta ye min be fɛnw lɔnniya, bɔli yɛlɛmani, ani funteni ɲɔgɔndan fɛɛrɛw don ɲɔgɔn na, minw labɛnna ka ultra-small flow (0,1–2 mm) dilan ka se ka funteni yɛlɛma ka ɲɛ. Fɛɛn jɔnjɔnw ye nin ye:

1. Aliminiyɔmu Alloy ka minanw labɛnni .

MCHEw lo be baara kɛ fɔlɔ ni aliminiyɔmu nɛgɛw ye (i n’a fɔ, 3003, 6061) k’a sababu kɛ u ka nɔgɔya, funteni yɛlɛmani ye, ani sɔngɔ-effectness.

Minɛnw sugandili: High-prite aluminum ingots be ɲagami ni fɛnw ye minw be se ka yɛlɛma (magnesium, silikɔni) walisa ka mekaniki fanga ni nɔgɔ kɛlɛ, ka ASTM B209 walima EN 573-3 sariyaw dafa.

ka kɔn ka baara kɛ: Ingot yɔrɔ minw be don (n’u be baara kɛ ni alkali ye) ani u be tigɛ (ni asidi nitiriki ye) walisa ka oksidiw, tuluw, wala nɔgɔw bɔ yen-} filankafoya la walisa k’a to u be bɔ ɲɔgɔn na ani ka ɲɔgɔn minɛ ka ɲɛ kɔfɛ.

2. Mikrokannɛli Tube bɔli .

O fɛɛrɛ be MCHEw ka "core" dilan: tubo pɛtɛninw minw ka mikrokanɛliw be ɲɔgɔn sɔrɔ.

Ɲɛfɔli sigicogo: Aliminiyɔmu nɛgɛlaman min kalaman (450–500 degere ) be yɛlɛma ka tɛmɛ tiɲɛn dɔ fɛ (2}}ɛnzenaned safe (ni mikrokanɛli- ye) min be i n’a fɔ hydraulique. Dilan dilan cogo be kanɛli bonya dantigɛ ka ɲɛ (a ka ca a la .<1 mm for high-efficiency models) and distribution.

bonyali hakɛ: O yɔrɔ pɛtɛnin min bɔra, o nɛnɛna joona (a fiɲɛ wala jii be se ka faga) walisa a ka se ka to a janya la, o kɔ, a be tigɛ ka se a janya ma min ka ɲi (ka bɔ 0,5 m la ka taga se m 6 ma, ka kɛɲɛ n’a baara ye).

Kalan kɛcogo ɲuman: Mikromɛtiriw be kanali bonya, kogo bonya, ani pɛtɛnin-}tolerances sɛgɛsɛgɛ ±0,02 mm kɔnɔ walisa ka se ka ji bɔli bali.

3. A be Stamping & Falenfɛnw sɔrɔ .

Finiw be fara tubo pɛtɛninw kan walisa ka funteni yɛlɛmani yɔrɔ bonya (fɛn jɔnjɔn min be MCHE ka baarakɛcogo la).

Tagamasiɲɛw kɛcogo: Aliminiyɔmu sɛbɛw (0,1–0,2 mm ka bon) be don yɔrɔ dɔ la min be se ka yɛlɛma ka kɛ fin cogoyaw ye- kasa ye, o ye finw ye minw be yɛlɛma (a fiɲɛ be bɔ) wala a be nɛgɛw nɔrɔ (waati la.

Ka kɔn-Walili furakɛli .: Fiɲɛw be se ka kɛ ni yɔrɔw ye (i n’a fɔ, kromamati yɛlɛmani fani) walisa ka nɔrɔli fisaya ni brazi ye ani ka post-}brazi fanga bonya.

4. Lajɛnba (Tube-Fin ɲɔgɔndan)

Tulu ni finw be lajɛn ka kɛ "kalaya yɛlɛmalan yɔrɔ" ye-then ka baarakɛcogo jɔnjɔn yɔrɔ.

Layered .: Filati nɛgɛw be ɲɔgɔn kan, ani finw be don nɛgɛw cɛma walisa ka sandwici- ka kɛ i n’a fɔ a be kɛ cogo min na. O yɔrɔ minw be weele ko clamps, olu lo be lajɛnba kɛ u nɔɔ na walisa u kana kɛ kelen ye.

dakun: O yɔrɔ min be nɛgɛw ni finw cɛ, o be mara .<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Furusiri min be kɛ ni mɔgɔw ye (A ka gwɛlɛ)

Bacum brazing ye fɛɛrɛ jɔnjɔn ye min be nɛgɛw pɛtɛninw nɔrɔ ɲɔgɔn na kudayi - {{ 1}}n ɲɔgɔn na i n’a fɔ laada sɔgɔli, a b’a to a be fanga sɔrɔ ani a ka funteni be yɛlɛma.

Flux aplikasiyɔn: Aliminiyɔmu -silisli (Al-Si) brazi min be yɛlɛma (yɛlɛmani yɔrɔ ~577 degere ) be fiyɛ walima k’a don yɔrɔ min lajɛnna ka oksidi bali ka mɛn.

Sugandili min be kɛ ka mɔgɔw lasun u ka baara kɛ: A kɔnɔyɔrɔ be bila furɛn lakolon kɔnɔ (a yɔrɔ min be yɛlɛma .<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.

balan: Furu be nɛnɛ dɔɔni dɔɔni (a be degere 50–100 /lɛrɛ) walisa ka dɔ bɔ funteni gɛlɛya la, ka mikrokrakiw bali ka don mikrokanniw kɔnɔ.

6. Ka baara kɛ ani ka pɔri jati .

O yɔrɔ min be ni brazi ye, o be baara kɛ walisa ka pɔriw fara jii donyɔrɔ/bɔyɔrɔ kan.

I ka se ka baara kɛ: CNC dɔ ye fɛn laban tigɛ ka kɛ fɛn laban hakɛ ye (misali la, 300×400 mm jagokɛlaw ka MCHEw kama), ni nɛnɛfɛn ye min be kɛ ka funteni- min be se ka yɛlɛma.

Port Drilling & Tapping: U be pɛtɛninw kuncɛw sɔgɔ ka yɔrɔw dilan, o kɔ, u be digi ka juruw fara a kan (i n’a fɔ, M10 wala 1/4 NPT) walisa ka firizidɛri yɔrɔw nɔrɔ ɲɔgɔn na. Sakokɛminanw be nɛgɛw bɔ walisa ka kanɛliw balili bali.

7. Degun ani Leak latigɛli .

MCHEw ka kan ka ji bɔ ka gwɛ- ka se ka yɛlɛma (kɔrɔfɔli firifiri- min basiginin be AC ​​walima firizidɛri kan).

Kɔrɔbɔli kɔrɔbɔli: 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 b’a yira ko ji be bɔ.

Helium Leak latigɛli: A ka ca a la, a be se ka kɛ ko a be se ka kɛ ko a be se ka kɛ ko a ka mɔgɔw be se ka ɲɔgɔn minɛ. 2 彼は,1×10⁹ Pam3/s ye).

8. Surface furakɛli ani Anti{1}}Sɛbɛnni (Sugandili) .

MCHE minw be kɛ yɔrɔ gwɛlɛw la (i n’a fɔ, baji wala yɔrɔ jan-humidite paramɛtiriw), nɔgɔko latangali wɛrɛw be kɛ:
