1: Lub ntsiab lus ntawm Aluminium Fins
Fins yog cov khoom tseem ceeb tshaj plaws ntawm cov phaj-fin kub exchangers. Cov txheej txheem hloov hluav taws xob feem ntau ua tiav los ntawm fins, thiab tsuas yog ib feem ua tiav ncaj qha los ntawm kev faib tawm.
Kev sib txuas ntawm cov fins thiab cov muab faib yog zoo meej brazing, yog li feem ntau ntawm cov cua sov yog pauv mus rau lub txias cab kuj los ntawm cov fins thiab muab faib.
Txij li thaum lub tshav kub hloov ntawm cov fins tsis ncaj qha tshav kub hloov, cov fins kuj hu ua "secondary surfaces".
Cov fins kuj ua lub luag haujlwm txhawb nqa ntawm ob qhov kev faib tawm. Txawm hais tias cov fins thiab partitions nyias nyias, lawv muaj lub zog siab thiab tuaj yeem tiv taus siab. Cov fins yog stamped los ntawm nyias 3003 txhuas ntawv ci, thiab lub thickness feem ntau yog los ntawm 0.15mm mus rau 0.3mm.
2: Hom fins
Feem ntau hais lus, muaj ntau hom fins:
● Plain kawg
● Offset fin
● Perforated fin
● Wavy fin
● Zoo louvered
2.1: Plain kawg
Piv nrog rau lwm cov qauv ntawm cov fins, cov fins ncaj muaj cov yam ntxwv ntawm cov hluav taws xob me me hloov coefficient thiab ntws tsis kam.
Hom fin no feem ntau yog siv rau hauv cov xwm txheej uas qhov kev xav tau ntawm cov dej ntws tsis zoo yog qhov me me thiab nws tus kheej hloov pauv cov coefficient yog qhov loj (xws li kua sab thiab theem hloov).
2.2: Offset fin
Sawtooth fins tuaj yeem suav tias yog cov fins tsis tu ncua tsim los ntawm kev txiav cov fins ncaj nraim rau hauv ntau ntu luv thiab ua rau lawv nyob rau qee lub sijhawm.
Hom fin no muaj txiaj ntsig zoo hauv kev txhawb nqa cov dej turbulence thiab rhuav tshem cov txheej txheem thermal tiv thaiv ciam teb. Nws yog ib qho kev ua tau zoo fin, tab sis cov dej tsis kam kuj tseem nce ntxiv.
Sawtooth fins feem ntau yog siv rau hauv cov xwm txheej uas yuav tsum tau hloov kho kom sov (tshwj xeeb tshaj yog nyob rau sab roj thiab sab roj).
2.3: Perforated fin
Cov porous fin yog tsim los ntawm kev xuas nrig ntaus qhov hauv cov ntawv ci txhuas thiab tom qab ntawd stamping nws.
Qhov ntom ntom ntom me me ntawm cov fins txuas ntxiv rhuav tshem cov txheej txheem thermal tiv thaiv ciam teb, yog li txhim kho cov cua sov ua haujlwm. Qhov ntau qhov yog qhov tsim nyog rau kev faib tawm ntawm cov kua dej, tab sis tib lub sijhawm, lawv kuj txo qhov kub hloov chaw ntawm cov fins thiab txo cov fin lub zog.
Cov porous fins feem ntau yog siv rau hauv phau ntawv qhia vanes lossis cov ntawv hloov theem. Vim lawv qhov nruab nrab kub hloov coefficient thiab ntws tsis kam, lawv kuj tau siv hauv intercoolers.
2.4: Lub cev muaj zog
Corrugated fins yog tsim los ntawm xuas nrig ntaus aluminium ntawv ci rau hauv ib qho kev sib tw ua kom muaj qhov nkhaus ntws.
Los ntawm kev hloov pauv cov kev coj ua ntawm cov kua dej tas li, qhov kev kub ntxhov, kev sib cais thiab kev puas tsuaj ntawm cov txheej txheem thermal tiv thaiv ciam teb ntawm cov kua yog nce, thiab cov nyhuv yog sib npaug rau kev tawg ntawm cov fin.
Qhov denser lub corrugation thiab qhov loj ntawm qhov amplitude, qhov ntau nws tuaj yeem txhim kho cov cua sov hloov.
Los ntawm peb cov ntaub ntawv ntsuam xyuas, qhov kub hloov pauv kev ua tau zoo ntawm corrugated fins yog sib npaug rau cov serrated fins. Tsis tas li ntawd, corrugated fins muaj lwm yam tseem ceeb: lawv tsis yooj yim los ntawm cov khib nyiab, thiab txawm tias lawv raug thaiv, cov khib nyiab yooj yim tshem tawm.
2.5: Zoo Louvered
Lub shutter blade yog ib qho fin txiav ntawm ib qho kev ncua deb nyob rau hauv cov kev taw qhia ntawm cov kua ntws los ua ib tug shutter zoo.
Nws kuj yog ib qho tsis txuas ntxiv, thiab nws cov kev hloov pauv cua sov zoo ib yam li cov hniav serrated thiab corrugated hniav. Nws qhov tsis zoo yog tias qhov txiav yog yooj yim thaiv los ntawm cov av.
Cov lus qhia tshwj xeeb muab los ntawm Atlas Oilfree department feem ntau hais tias hom fin no yuav tsum tsis txhob siv. Tab sis hom fin no muaj qhov zoo dua. Nws tuaj yeem dov tawm ntawm kev kub ceev ntawm lub tshuab fin dov, nrog kev ua haujlwm siab.
Nws yog feem ntau siv nyob rau hauv huab hwm coj-tsim tshav kub exchangers nyob rau hauv kev lag luam automotive.
