Uburyo bwo Gukora Amashanyarazi ya Microchannel (MCHEs)

Umusaruro wa MCHEs nuburyo busobanutse - inzira itwara ihuza ubumenyi bwibintu, gushushanya ibicuruzwa, hamwe nubuhanga bwo guhuza amashyuza, bigamije gukora ultra - imiyoboro ntoya (0.1-2 mm) kugirango ihererekanyabubasha neza. Intambwe zingenzi nizi zikurikira:

1. Gutegura ibikoresho bya Aluminium

MCHEs ikoresha cyane cyane amavuta ya aluminiyumu (urugero, 3003, 6061) bitewe nuburemere bwabyo, ubushyuhe bwinshi, hamwe nigiciro -.

Guhitamo Ibikoresho.

Gutunganya: Ubuso bwa Ingot buragabanuka (ukoresheje isuku ya alkaline) hanyuma ugatororwa (hamwe na acide ya nitricike) kugirango ukureho okiside, amavuta, cyangwa umwanda - byingenzi kugirango habeho gusohora kimwe no kuzuza ubuziranenge nyuma.

2. Microchannel Flat Tube Gukuramo

Iyi ntambwe ikora "intangiriro" ya MCHEs: tebes iringaniye hamwe na micran nyinshi zingana.

Gushiraho. Igishushanyo cyo gupfa kigena neza ingano yumurongo (mubisanzwe<1 mm for high-efficiency models) and distribution.

Ingano: Umuyoboro usohotse ukonjeshwa vuba (ukoresheje umwuka cyangwa kuzimya amazi) kugirango ugumane umutekano muke, hanyuma ugabanye uburebure busabwa (kuva kuri m 0,5 kugeza kuri m 6, bitewe nibisabwa).

Kugenzura ubuziranenge: Micrometero ya Laser igenzura umuyoboro wa diameter, uburebure bwurukuta, hamwe nuburinganire - kwihanganira kugenzurwa muri mm 0,02 mm kugirango hirindwe ibitagenda neza.

3. Fins Ikimenyetso & Gushiraho

Amafranga yongewe kumuyoboro uringaniye kugirango wagure ubuso bwohereza ubushyuhe (ikintu cyingenzi mubikorwa bya MCHE).

Ikimenyetso cya kashe: Amabati ya aluminiyumu (0.1–0.2 mm z'ubugari) agaburirwa mumashini yerekana kashe kugirango habeho ishusho ya fin - ibishushanyo bisanzwe birimo udusimba twa louvered (kugirango twongere imbaraga zo mu kirere) cyangwa udusimba twa fagitire (kugirango duhuze).

Mbere - Kuvura.

4. Inteko Nkuru (Tube - Kurangiza)

Imiyoboro ya flat na fins byegeranijwe muri "ubushyuhe bwo guhinduranya ubushyuhe" - igice cyibanze gikora.

Gutondekanya: Imiyoboro ya flat ihujwe kuburinganire, hamwe nudusimba twinjijwe hagati yigituba cyegeranye kugirango ube sandwich - nkimiterere. Clamps z'agateganyo zifata inteko kugirango ikumire nabi.

Kugenzura icyuho: Ikinyuranyo hagati yigituba nudusimba kibitswe kuri<0.05 mm to ensure full contact during brazing, minimizing thermal resistance at the interface.

5. Gukoresha Vacuum (Kwishyushya Ubushyuhe)

Vacuum brazing nintambwe yingenzi ihuza burundu imiyoboro iringaniye hamwe nudusimba mumatembabuzi - intoki zikomeye - bitandukanye no kugurisha gakondo, itanga imbaraga zuburyo bukomeye hamwe nubushyuhe bwumuriro.

Porogaramu.

Gutunganya itanura rya Vacuum: Intangiriro ishyirwa mu itanura rya vacuum (igitutu<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.

Gukonja: Itanura rikonjeshwa buhoro (dogere 50-100 / isaha) kugirango bigabanye ubushyuhe bwumuriro, birinda microcrack muri microchannel.

6. Gukata no Gukora Port

Intoki zometseho zitunganyirizwa kongeramo ibyambu byamazi yinjira / asohoka.

Gukata.

Gucukura icyambu & Kanda: Impera yigituba kiringaniye iracukurwa kugirango ikore ibyambu byinshi, hanyuma ikande kugirango wongereho insinga (urugero, M10 cyangwa 1/4 NPT) kugirango uhuze imirongo ya firigo. Ibikoresho byo gukuraho bikuraho icyuma kugirango wirinde guhagarika imiyoboro.

7. Kugerageza Umuvuduko & Kumenya Kumeneka

MCHEs isaba gukomera - gukomera (ingenzi kuri firigo - ishingiye kuri AC cyangwa firigo).

Ikizamini cy'ingutu: 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 kumeneka.

Kumenya Helium.

8. Kuvura Ubuso & Kurwanya {{1} ating Kwangirika kwa ruswa (Bihitamo)

Kuri MCHEs ikoreshwa mubidukikije bikaze (urugero, marine cyangwa hejuru - igenamiterere ry'ubushuhe), hiyongereyeho uburinzi bwa ruswa:

Gusaba: Fenolike resin, epoxy, cyangwa fluoropolymer yatewe cyangwa yatewe amashanyarazi hejuru yubutaka. Ubunini bwa coating bugenzurwa kuri 20-50 mm kugirango habeho kuringaniza ruswa no gukora neza.

Gukiza.

9. Kugenzura Ubuziranenge Bwuzuye & Gupakira

Ikizamini Cyuzuye.

Gupakira.

Ubu buryo butuma MCHEs yujuje ibyangombwa bisabwa kugirango ukoreshwe nko gukonjesha ubucuruzi, guhumeka imodoka, hamwe na sisitemu ya HVAC - kuringaniza imikorere, guhuzagurika, no kwizerwa.

HYLITA ifite ibikoresho byikora byuzuye hamwe nimirongo yo guteranya, imirongo yumusaruro wuzuye wa brazing, hamwe numurongo wo gupima helium wuzuye.

1. Ibikoresho byinteko byikora byuzuye

Byuzuye Byashizweho Kashe Yumurongo Kubintu ByingenziIbisubizo byiyongereyeho 49% muburyo bwo kwizerwa no kunoza 67% muburyo bwo gutanga ibikoresho bitari -.

Byuzuye Byuzuye Byarangiye Ibicuruzwa IntekoGushoboza 51% kunoza imikorere yinteko no kuzamura ireme ryiza kugeza 99.8%.

2. Ibikoresho Byogukora Byuzuye Byuzuye

Byuzuye Byuzuye Imirongo Yumusaruro hamwe na Tunnel - Ubwoko bwa Brazing ItanuraBiganisha ku kuzamuka kwa 53% kwizerwa ryiza, hamwe nigipimo cyibicuruzwa byarangiye byarangiye bigera kuri 99.7%.

Byuzuye Byuzuye Imirongo Yumusaruro hamwe na Vacuum Brazing ItanuraKugera ku gipimo cya 57% mu kwizerwa kwiza, hamwe nigipimo cyibicuruzwa byarangiye byarangiye bigera kuri 99.7%.

3. Ibikoresho Byuzuye Byuzuye / Ibikoresho byo Kugerageza

Byuzuye Byikora Byuzuye Ubuso Bwuzuye ImirongoGutanga iterambere rya 55% muburyo bwiza bwo kwizerwa, hamwe nigipimo cyibicuruzwa byarangiye byarangiye bigera kuri 99.8%.

Byuzuye Byuzuye Vacuum Helium Imirongo Yipimisha100% y'ibicuruzwa byose bipimisha vacuum helium yamenetse, byemeza ko 100% yujuje ibyangombwa byo gupima helium mbere yo kubyara.
