Zvakanakira zveMicrochannel Heat Exchangers (MCHEs) Zvichienzaniswa neTraditional Heat Exchangers (Copper Tube Aluminium Fin Heat Exchangers)
Superior Heat Transfer Kubudirira
MaMCHE ane machanera akawanda-madiki emukati (kazhinji 0.1–2 mm mudhayamita) uye nzvimbo yakakwirira-ku{4}}yeshiyo yevhoriyamu. Magadzirirwo aya anowedzera kudhumhana kuri pakati pemudziyo wekupisa kupisa (sefiriji yakaita seR134a kana R404A) nenzvimbo yekuchinjisa kupisa, zvichiita kuti kupisa kuwedzere ne 42% kana kudarika zvichienzaniswa nemhando dzemafin chubhu. Kuwedzera kuvhiringika kwemvura mumakicheni madiki kunowedzera kudzikisira kupisa, zvichiita kuti MCHEs dzive dzakanakira kushandisa simba{11}}zvakadai semafiriza ekutengesa uye makabati ekuratidzira.
Compact Size uye Lightweight
Yakagadzirwa ne-zvese zvealuminium uye yakasanganiswa fin-flat chubhu chimiro (kuburikidza nemusono welding), MCHEs dzakasimba zvakanyanya uye dzakareruka. Paavhareji, vanotora nzvimbo yakaderera ne 32–51% uye huremu hwakaderera ne 42–61% pane yechinyakare mhangura -based heat exchanger ine huremu hwakafanana. Kubatsira uku kwakakosha munzvimbo-zvisina kuvharirwa, zvakaita semotor air conditioning, compact refrigeration units, kana masystem emumba eHVAC.
Lower Material uye Operating Costs
Aluminium, iyo inonyanya kukosha yeMCHEs, inodhura zvakanyanya-kupfuura mhangura (chinhu chikuru chekuchinjana kwechinyakare), ichideredza mitengo yezvigadzirwa ne20-30%. Pamusoro pezvo, maMCHE anoda mari yefiriji shoma (kusvika pa50–70% yakaderera) nekuda kwevhoriyamu idiki yemukati, inoderedza-mari yekushandisa kwenguva refu uye kuenderana nemitemo yezvakatipoteredza (semuenzaniso, F-Mitemo yeGasi) inorambidza kushandisa firiji zvakanyanya.
Kuvimbika Kwemaitiro Akavandudzwa
Matanho ekugadzira epamusoro (somuenzaniso, vacuum brazing yezvose-aruminiyamu zvinoumba) zvinogadzira kubatana kusina musono pakati pezvimbi nemachubhu akati sandara mumaMCHE, kubvisa maburi anokonzera kusanzwa kwemafuta kana kubuda mufiriji mumachubhu echinyakare{3}}mafin exchangers. Ichi chimiro chisina musono chinonatsiridzawo kuramba vibration uye kupisa bhasikoro, kuwedzera hupenyu hwesevhisi munzvimbo dzine simba (senge marori efiriji anofambisa).

Inferior Corrosion Resistance
Aruminiyamu zvinhu, nepo zvisingaremekedzi, zvine kusaita ngura kwakaderera pane mhangura-kunyanya munzvimbo dzakaoma (semugungwa, nzvimbo dzine mwando wakakwira-, kana kushandisa mvura ine acidic/alkaline). Pasina mamwe majeti ekudzivirira-kuora (semuenzaniso, phenolic resin coatings), MCHEs inogona kutambura nearuminiyamu oxidation kana pitting, inoda kugara ichigadziriswa kana kuchinjwa mumamiriro ekuora.
Yepamusoro Maintenance Kuoma uye Mutengo
Iyo yakabatanidzwa, compact dhizaini yeMCHEs inoita kugadzirisa kunetsa. Kusiyana nechubhu yechinyakare-mafin exchanger (apo machubhu akakuvadzwa kana zvimbi zvinogona kutsiviwa imwe neimwe), kakanganisika kamwe chete mumamicrochannels eMCHEs kazhinji zvinoda kutsiva chikamu chose. Izvi zvinowedzera mari yekugadzirisa uye nguva yekudzikira, zvikuru-mashandisirwo makuru eindasitiri.
Yepamusoro Yekutanga Kugadzira Investment
MCHEs inoda michina yekugadzira chaiyo (eg, micro-extrusion for flat tubes, high-temperature vacuum brazing) nemichina yakakosha. Nepo mitengo yezvinhu yakadzikira, mari yekudyara mumitsara yekugadzira yakakwira 2-3 zvakapetwa kupfuura zvechinyakare zvinopisa kupisa. Izvi zvinoita kuti MCHEs ishaye mari pakugadzira madiki{{8}batch kana mapurojekiti ebhajeti akaderera{{9}.
Yakakwana Yepamusoro{{0}Temperature Applicability
Aluminium's melting point (inenge 660 dhigirii) uye kugadzikana kwekupisa kwakaderera pane yemhangura (inonyungudika ~ 1085 degree). Mumamiriro ekunze-pakupisa (semuenzaniso, mabhaira emuindasitiri,{6}}kudzoreredza kupisa kwemarara), MCHEs inogona kuderedzwa kusimba kana kupisa kwemafuta, nepo mhangura yechinyakare{7}}inochinjanisa inochengetedza kushanda kuri nani mumamiriro ezvinhu akadaro.
Material Selection Sensitivity
Kana saizi yechiteshi iri <0.5 mm, mutsauko wekuita kupisa kwekushisa pakati pezvinhu zvakaita sendarira uye simbi isina tsvina inogona kusvika 20%. Iwo akakosha ekugadzira zvikumbaridzo anofanirwa kutariswa zvizere pamwe chete nekushomeka kwekupokana nezvinodiwa.
Flow Channel Shape Gain
Complex chiteshi zvimiro (semuenzaniso, serpentine/serrated) zvinowedzera kupisa kwekushisa ne 1.2 kusvika 1.4 nguva zvichienzaniswa nematanho akatwasuka, asi zvakakosha kuenzanisa kutengeserana-kubva pa15% -25% kuwedzera mukudonha kwekumanikidza.
