Microchannel Coils (MCHEs) ni hpe galaw shapraw ai lam.

MCHE ni hpe galaw shapraw ai lam gaw, arung arai hpaji, extrusion molding, hte thermal matut mahkai hpaji masa ni hpe hpawng de ya ai, hkrak hkrak rai nga ai, ultra-small flow channels (0.1–2 mm) hpe galaw shapraw na matu, n-gun ja ai katsi ai hpe htawt sit lu na matu, hkrak hkrak re ai. Madung lahkam ni gaw lawu na hte maren rai nga ai:

1. Aluminium alloy arung arai ni hpe hkyen lajang ai lam

MCHE ni gaw madung hku nna aluminum alloys (ga shadawn, 3003, 6061) hpe lang ma ai, shanhte a n-gun n law ai, n-gun ja ai n-gun n-gun, manu jahpu-el hkra machyi ai majaw re.

Arung arai ni lata la ai lam: High{0}}purity aluminum inots ni hpe alloying elements (magnesium, silicon) hte kayau nna, jak rung n-gun hte n-gun n-gun hpe ninghkap lu ai atsam hpe jat ya ai, ASTM B209 (sh) EN 573-3 madang ni hpe hkan sa ai.

tau hkrau galaw ai: Ingot surfaces ni hpe n-gun n rawng ai (alkaline cleaner ni hpe lang nna) hte oxides, sau, shing nrai, n san seng ai ni hpe yeng seng kau na matu (dilute nitric acid hte) hpe lata la ai (dilute nitric acid hte) tara tawt lai ai ni hpe yeng seng kau na matu, hpang de langai sha re ai extrusion hte brazing quality hpe hkam la lu na matu re.

2. Microchannel Flat Tube madun poi

Ndai lahkam gaw MCHE ni a "core" hpe hpaw ya ai: parallel microchannel law law lawm ai flat tubes ni.

Extrusion galaw ai: Aluminum alloy billet (450–500℃) hpe hka htung n-gun dat hku nna, hkrak ai-}}}} ai hka htung ni hte) hku nna, n-gun dat ai. Die design gaw channel size hpe hkrak dawdan ya ai (typically<1 mm for high-efficiency models) and distribution.

Size Calibration: Extruded flat tube hpe lawan ai hku katsi shangun ai (nbung (sh) hka n-gun) gaw dimensional stability hpe n-gun n-gun hpe n-gun jaw na matu, ra ai galu kaba ai lam (0.5 m kaw nna 6 m du hkra, application hta hkan nna) hpe gang je kau ai.

Quality Check: Laser micrometers ni gaw channel diameter, bunghku n-gun, hte n-gun n rawng ai ni hpe ±0.02 mm laman hta hkang lu ai majaw, hka lim ai lam hpe ninghkap lu ai atsam n bung ai hpe koi lu na matu hkang ai.

3. Fins stamping &forming

Fins ni hpe flat tubes ni hta jat bang nna, katsi ai hpe htawt sit ai shara hpe jat ya ai (MMCHE n-gun atsam hta ahkyak ai lam langai).

Stamping Process: Aluminium sheets (0.1–0.2 mm galu ai) ni hpe hkrak ai stamping press de bang nna, fin pattern ni-}combat hkrang shapraw ai lam ni hta, louvered fins (nbung n-gun jat wa na matu) shing nrai, corugated fins (comactness a matu) lawm ai.

Pre{0}} Tsi lajang ai lam hpe gram lajang ai: Fins ni gaw ntsa kaw na tsi lajang ai lam hpe galaw mai ai (ga shadawn, chromate conversion coating) hpe brazing flux hte n-gun jat wa hkra galaw ya nna, post{2}}brazing corrosion hpe grau kaja hkra galaw ya lu ai.

Flat tubes hte fins ni hpe "heat exchanger core"{0}} hpe madung bungli galaw ai unit langai mi de shinggyin bang da ai.

Layered Stacking: Flat tubes ni hpe parallel hku shingdaw nna, makau grup yin na tube ni a lapran hta fils ni hpe bang nna sandwich- bung ai hkrang hpe galaw ai. Temporary clamp ni gaw n tara ai lam n byin hkra, zuphpawng hpe shara kaw tawn da ai.

Gap hpe hkang ai: tube hte fins lapran na gap hpe 2019 ning hta tawn da ai.<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Vacuum Brazing (Termal Joining)

Vacuum brazing gaw, flat tubes hte fins ni hpe prat tup matut mahkai nna, hka lim ai-tight core{1}}un zawn re ai htunghking bu hpun palawng ni hpe, n-gun ja ai n-gun hte nbung n-gun hpe hkam la lu hkra galaw ya ai ahkyak ai lahkam rai nga ai.

Flux jai lang ai lam: Aluminium{{0}silicon a n-gun n rawng ai daw (Al- Si) brazing flux (melting point ~577℃) hpe hka lum ai aten hta n-gun n rawng hkra, shinggyin da ai core ntsa de chya da ai (sh) dip dat ai.

Vacuum wan wut ai lam: Core hpe n-gun n-gun (pressure) hta bang da ai (pressure<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.

katsi ai: Wan n-ga hpe loi loi hte katsi shangun ai (50–100℃/hour).

6. Tsin yam & Port Machining

Brazed core hpe hka shang/outlet a matu connection port ni hpe bang na matu galaw ai.

Core Cutting: CNC langai gaw, hpang jahtum na prut prut ai arung arai (ga shadawn, 300×400 mm) hpe gang je kau ai hpe mu lu ai, katsi ai-} a majaw byin pru wa ai nsam galai shai ai lam hpe koi lu na matu, katsi ai hpe lang ai.

Port Drilling & Tapping: Flat tubes ni a jahtum ni hpe htu nna, manifold port ni hpe galaw nna, n-gang ni hpe jat bang na matu (ga shadawn, M10 or 1/4 NPT) refrigerant line ni hpe matut mahkai na matu. Deburring tools ni gaw channel hpe pat shingdang ai hpe pat shingdang na matu metal shaving ni hpe yeng seng kau ya ai.
