Finned tubes yog siv los txhim kho cov cua sov ua haujlwm, feem ntau yog los ntawm kev ntxiv cov fins rau saum npoo ntawm lub tshav kub exchanger raj kom nws qhov chaw sab nrauv.

Yog li ua tiav lub hom phiaj ntawm kev txhim kho kev sib pauv hluav taws xob, xws li lub raj xa hluav taws xob. Lub condenser yog ib feem ntawm lub tshuab cua txias uas tuaj yeem hloov cov cua sov los ntawm cov kav dej mus rau cov cua nyob ze ntawm cov kav dej. Feem ntau cov tsheb tau muab tso rau pem hauv ntej ntawm lub tank dej. Ib qho khoom siv uas hloov cov pa los yog vapor rau hauv cov kua. Fais fab nroj tsuag yuav tsum tau siv ntau condensers kom condense lub chav emitted los ntawm lub turbine; Nyob rau hauv ib lub tub yees, lub condenser yog siv los condense refrigerant vapors xws li ammonia thiab Freon. Hauv kev lag luam petrochemical, condensers yog siv los ua kom cov hydrocarbons thiab lwm yam tshuaj vapors. Cov cuab yeej uas hloov cov chav rau hauv cov kua thaum lub sijhawm distillation yog hu ua condenser. Tag nrho cov condensers ua haujlwm los ntawm kev tshem tawm cov cua kub ntawm cov pa los yog vapor.

Rau cov tshuab cua txias cua txias uas xav tau kev tswj xyuas meej thiab qhov chaw ua haujlwm hnyav, evaporative condensers feem ntau yuav ua tau raws li cov txheej txheem tswj. Cov ntawv thov engineering tau pom tias siv cov khoom no los hloov cov khoom siv "dej-txias condenser + cua txias ntauwd" txoj kev tuaj yeem rov ua dua qhov kev nqis peev thawj zaug hauv ib xyoos, nrog cov txiaj ntsig tseem ceeb ntawm kev lag luam.

2. Txhim kho cua sov hloov finned raj feem ntau siv hauv condensers

Cov txheej txheem hloov hluav taws xob yog cov txheej txheem uas cov cua sov hloov ntawm ib qho dej los ntawm cov phab ntsa khoom mus rau lwm cov kua. Hauv kev xyaum ua engineering, txhim kho qhov kev hloov pauv ntawm cov cua sov ntawm cov khoom siv hluav taws xob feem ntau pib nrog kev txhim kho cov txheej txheem hloov hluav taws xob ntawm qhov nruab nrab ntawm ob sab thiab cov phab ntsa sab hauv thiab sab nraud ntawm lub tshav kub hloov pauv. Common enhanced heat transfer technologies muaj xws li:

(1) Txheej txheej;

(2) Rough nto;

(3) Extended nto;

(4) Ntau yam hauv thiab sab nraud threaded kav;

(5) Cov khoom cuam tshuam;

(6) Additives;

(7) Kev cuam tshuam cua sov.

Ntawm ntau yam kev hloov kho cua sov thev naus laus zis, kev txhim kho fins ntawm phab ntsa yog ib qho tseem ceeb ntawm kev txhim kho cov cua sov thiab tau siv dav hauv engineering. Finned tube heat exchangers muaj cov yam ntxwv ntawm kev hloov hluav taws xob zoo thiab cov qauv compact, thiab tau siv dav hauv ntau yam xws li cov tub yees thiab cua txias, cov cuab yeej siv dav hlau, cov khoom siv hnub ci, thiab cov khoom siv hluav taws xob. Daim ntawv thov nyob rau hauv condensers yog tshwj xeeb tshaj yog muaj.

Muaj ntau hom finned raj, thiab ntau yam tshiab tau tshwm sim tas li, thiab tseem muaj kev tshawb fawb ntau hauv cheeb tsam no [4-6]. Feem ntau, finned tubes tuaj yeem raug cais raws li kev siv thev naus laus zis, fin zoo, cov khoom siv, thiab kev siv.
