Uburyo bwo gukora Ibikorwa vya Microchannel (MHEs)

Ivyo gukora MHEs ni uburyo bwiza- ubuhinga bushiramwo ubuhinga bw’ibintu, ubuhinga bwo gusohora, n’ubuhinga bwo gufatanya ubushuhe, bugenewe guhingura imirongo y’uruja n’uruza rw’amazi (0.1–2 mm) kugira ngo ubushuhe buvemwo neza. Intambwe nyamukuru ni ibi bikurikira:

1. Gutegura ibikoresho vy'ubuhinga bwa none

MHEs zikoresha cane cane ivyuma vy’aluminium (nk’akarorero, 3003, 6061) kubera uburemere bwavyo bwo gukoresha ubushuhe buyoroshe, uburemere bw’ubushuhe bwinshi, n’igiciro- kugira ngo bibe vyiza.

Guhitamwo Ibikoresho: High- Ingendo y’aluminium ivangwa n’ibintu vy’ugufatanya (magnesium, silikoni) kugira ngo haboneke inkomezi z’ubuhinga n’uguhungabana kw’ivyuma, bihuye n’ingingo ngenderwako za ASTM B209 canke EN 573-3.

Gutegura: Ivyuma vy’ibuye biragabanywa (gukoresha ivyuma bisukura alkaline) kandi bikabise (n’aside nitrit) kugira ngo bikureho oxides, amavuta, canke ibihumanye- kugira ngo umuntu amenye neza ko asohoka mu buryo bumwe n’uburyo bwo gutera ivyatsi mu nyuma.

2. Ubucrochannel Flat Tube Extrusion

Iyi ntambwe ni yo ikora "icuka" c'ama MHEs: amatiyo y'imirongo n'imirongo myinshi ihuye.

Urutonde rw'Urugendo: Igiharuro c’ivyuma vy’ivyuma (450–500℃) gisunikwa biciye mu buryo bubereye- urupfu rwapfuye (n’imirongo mito mito- Ivyimburwa vy’amazi) biciye ku nzira y’amazi. Igishushanyo c'urupfu kigena ubunini bw'imirongo (mu bisanzwe<1 mm for high-efficiency models) and distribution.

Ingano: Igipande c’amazi gipfutse kirakonja cane (biciye mu kuzimya umuyaga canke amazi) kugira ngo kigume gihagaze neza, hanyuma kigaca ku burebure bukenewe (kuva kuri 0,5 m gushika ku metero 6, bivanye n’ugukoresha).

Uburyo bwiza: micrometers y’imirongo igenzura umurongo w’umurongo, uburebure bw’uruhome, n’uburemere bw’ivyuma-bikorwa bigenzurwa mu ±0.02 mm kugira ngo ntihagire ukudahuza kw’uruja n’uruza.

3. Gushiramwo ibiharuro n'uguhingura

Amafaranga yongerwa ku nzira zisongoye kugira ngo hagure uburebure bw’ubushuhe (ikintu nyamukuru mu gukora neza MCHE).

Ingeso z'inzira: Ivyuma vy’ivyuma (0.1–0.2 mm) bishirwa mu rutonde rw’ibimenyetso vy’ukuri kugira ngo haboneke ibishushanyo vy’amabati{2}} Ivyimburwa birimwo amababa y’imbere (ku bijanye n’umuvurungano w’umuyaga) canke ivyuma vy’ivyuma (ku bijanye n’uburemere).

Imbere y'igihe- Ubuvuzi bwo Gushiramwo: Amafaranga ashobora gukoreshwa mu kuvurwa ku ruhande (nk’akarorero, uguhindura kw’ibara ry’umubiri) kugira ngo ashobore gufatanya n’ugutera imbere kw’ibara ry’agahama no gutuma inyuma y’inyuma - ubushobozi bwo gutera imbere.

4. Ikoraniro ry'ingenzi (Tube-Gutera)

Ivyuma vy'amazi n'amababa bikoranirizwa hamwe mu "guhindura ubushuhe"{{0}=igice c'ishimikiro c'ibikorwa.

Guhagarara neza: Amabendera y’amazi ahuye n’ibindi bihuye, n’amapine yinjijwe hagati y’imirongo iri hafi kugira ngo akore umukate w’umukate{0}} nk’umubumbe. Amafaranga y’igihe gito afata ikoraniro mu kibanza kugira ngo ntihagire uwudahuye.

Gucungera neza: Itandukaniro riri hagati y’ibinogo n’amafani riguma ku .<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Vacuum Brazing (Gukorana n'igihuhusi)

Igitero c’umuco ni intambwe ihambaye cane ifatanya ubudasiba imirongo y’amazi n’amafarasi mu nzira y’amazi asohoka- umurongo w’imbere-kurya nk’ugutera imbere kw’ibintu vya kera, bituma habaho inkomezi nyinshi z’imiterere n’ubushobozi bwo gutwara ubushuhe.

Gukoresha: Igipande gitoyi c’aluminium-silikoni (Al{1}}Si) uruzitiro rw’ivyuma (urudodo ~577℃) rurashirwa ku ntumbero y’umubiri kugira ngo ntizigire umwuka mu gihe c’ubushuhe.

Gukora neza ifuru: Ico kintu gishirwa mu mwobo w’ubusa (umukazo<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.

Gukonje: Uburari burakonja buhoro buhoro (50–100℃/isaha) kugira ngo bugabanye umubabaro w’ubushuhe, bugabuza ama microcracks mu bice bitobito.

6. Gutwara n'Ikarita

Ico gikoresho gikozwe mu gipfukisho gikozwe kugira ngo wongereko ivyuma vy’uguhuza kugira ngo umuntu ashobore kwinjira/gusohoka.

Ivyiza: A CNC yabonye ishingiro ku bunini bw’igicuruzwa ca nyuma (nk’akarorero, 300×400 mm ku bikoresho vy’ubudandaji vy’ubudandaji), n’ugukonjesha bikoreshwa mu kwirinda ubushuhe bw’ubushuhe.

Gukoresha n'ugushirwa mu ngiro: Amaherezo y’izo nzira y’amazi asongoye aracukurwa kugira ngo akore ibivuko vy’amabuye, hanyuma agashirwako kugira ngo yongereko indodo (nk’akarorero, M10 canke 1/4 NPT) kugira ngo ihuze imirongo y’ifiriji. Gukuraho ibikoresho bikuraho ivyuma kugira ngo ntihagire ivyuma bizibira.

7. Guteza imbere igerageza n'ugucapura

MHEs zisaba ko umuntu asohoka - Ubugororotsi (bikwiye ku bikoresho vy'ifiriji.

Igerageza ry'Igipimo: 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 yerekana ko hariho ukuvuza.

Uburemere bw'Ivyiyumviro: Ku bikoresho vy’ubuhinga bwa none (nk’akarorero, ubuhinga bwa AC), hakoreshejwe ubuhinga bwo gupima uburemere bw’ibintu kugira ngo umuntu amenye micro- ibimenyetso (bishika ku 1×10⁻⁻ Pa·m3/s).

8. Ubuvuzi bwo ku ruhande n'ubudahangarwa bw'umubiri-Igikoresho co gusenya (Ihitamwo)

Ku MCHEs zikoreshwa mu bidukikije bikomeye (nk’akarorero, ikiyaga canke hejuru- uburyo bwo gukingira), uburinzi bwongereweko burakoreshwa:

Gutegura Gukoresha: Ivyuma vy’ibara ry’agahama, epoxy canke fluoropolymer birashirwako canke vy’ivyuma vy’ivyuma ku ruhande rw’imbere. Uburemere bw’igipfukisho bugenzurwa ku 20–50 μm kugira ngo bugereranye ubushobozi bwo gusenyuka n’ubushobozi bwo gutanga ubushuhe.

Ivyiza: Inyenyeri ipfutse itekewe ku 120–180 mu minota 30–60 kugira ngo ukire igipfukisho, ibe igice kinini kandi kidashobora gutera.

9. Igenzura ry'uburyo bwa nyuma n'ugupakira

Igerageza ry'ubuhinga: Abagenzuzi basuzuma ingero (biciye ku mashini yo gupima), (ku bijanye n’utunenge nk’imivyimba canke ibisigarira vy’amazi), no gukora ibipimo vy’ubushobozi bwo guhindura ubushuhe (gukoresha umugende w’umuyaga kugira ngo upime igipimo co guhindura ubushuhe mu bihe bisanzwe).

package: MCHEs zifise ubushobozi zizingiwe mu bukonje- film kandi zipakiwe mu makarita y’ifu kugira ngo ntihagire ivyonona mu gihe c’ugutwara.

Ivyo bituma MHEs zishitsa ibisabwa bikomeye ku bikorwa nk’ugucagura ubudandaji, gukoresha umwuka w’imodoka, n’uburyo bwo gukoresha HVAC- ubuhinga bwo gukora, ubushobozi bwo gukora, n’ukwizigirwa.

HYLITA ifise imirongo y’uguhingura n’iteraniro, imirongo y’uguhingura ivyuma vy’ivyuma vy’ivyuma, n’imirongo y’igerageza y’ivyuma vy’ivyuma vy’ivyuma.

1. Inama y'Ikoraniro ry'Ikoraniro ryose
