Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib npaug ntawm cov khoom siv hluav taws xob sib txuas yog qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv yog qhov ua tau zoo heev vim tias nws tuaj yeem hloov pauv qhov siab tshaj plaws ntawm cov cua sov, qhov sib txawv ntawm cov khoom siv hluav taws xob sib txuas tsis tshua muaj txiaj ntsig vim nws tsis tuaj yeem hloov pauv qhov kub siab..
Lub tshuab hluav taws xob kub yog ib qho cuab yeej pab tshem tawm cov cua sov ntawm cov kua uas muaj qhov kub thiab txias. Raws li lawv cov txheej txheem, feem ntau muaj ob qhov kev faib tawm rau cov khoom siv hluav taws xob uas muaj npe hu ua: parallel flow thiab counterflow heat exchangers. Cov no tseem hu ua inline thiab crossflow heat exchangers, feem. Cov txheej txheem counterflow yog qhov sib txawv ntawm cov txheej txheem sib luag.
Dab tsi yog Counterflow Heat Exchanger (lossis Crossflow Heat Exchanger)?
Counterflow heat exchangers yog exchangers nyob rau hauv uas ob lub kua ntws nyob rau hauv parallel tab sis opposite lus qhia. Peb tuaj yeem categorize cov khoom siv hluav taws xob no nyob ntawm qhov kev npaj ntws. Cov feem ntau muaj xws li phaj, plhaub thiab raj, ob-pipe, ib theem, thiab multi-phase counterflow heat exchangers.
Daim duab 01: Lub Kub Kub Exchanger
Hauv cov khoom siv hluav taws xob sib hloov, cov ntu kub thiab txias yuav txav mus rau ib leeg. Hauv lwm lo lus, cov kev sib pauv no siv cov dej ntws uas txav mus rau qhov sib txawv rau ib leeg. Nws yog cov khoom siv hluav taws xob zoo dua piv rau lwm cov ntaub ntawv. Hauv cov cuab yeej no, cov cua kub ntws yog siab tshaj plaws. Yog li ntawd, qhov ua tau zoo kuj tseem siab dua li ntawm qhov sib npaug ntawm cov khoom siv hluav taws xob sib txuas. Tsis tas li ntawd, qhov ntsuas kub hauv cov kua dej txias tuaj yeem qee zaum dhau ntawm cov kua dej sov los ntawm qhov nkag.
Dab tsi yog Parallel Flow Heat Exchanger (lossis Inline Heat Exchanger)?
Ib qho sib npaug ntawm cov khoom siv hluav taws xob sib txuas yog ib hom kev sib hloov uas muaj cov kua dej sib npaug. Hauv lwm lo lus, cov kua dej uas muaj qhov kub thiab txias txias ob qho tib si txav mus rau tib qho kev taw qhia los ntawm cov raj sib cais, uas tso cai rau cov cua sov hloov ntawm cov kua kub kub mus rau cov kua kub qis.
txheej txheem no tsis tshua muaj txiaj ntsig piv rau cov txheej txheem counterflow vim tias cov txheej txheem no tsis tuaj yeem nqus qhov kub siab tshaj plaws los ntawm cov kua dej sov. Qhov no yog vim hais tias thaum ob lub kua txav mus rau tib qho kev taw qhia, qhov kub ntawm qhov sib txawv ntawm ob lub kua yuav maj mam qis. Txawm li cas los xij, txoj kev no tseem ceeb heev thaum cov dej ntws ntawm qhov hluav taws xob muaj qhov kub zoo sib xws ua ke, thiab peb kuj xav tau cov ntws no kom muaj qhov kub zoo sib xws.
Qhov txawv ntawm Counterflow thiab Parallel Flow Heat Exchanger yog dab tsi?
Lub tshuab hluav taws xob kub yog ib qho cuab yeej pab tshem tawm cov cua sov ntawm cov kua uas muaj qhov kub thiab txias. Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm cov khoom siv hluav taws xob sib txuas yog qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv yog qhov ua tau zoo vim tias nws tuaj yeem hloov pauv qhov siab tshaj plaws ntawm cov cua sov, qhov sib txawv ntawm cov khoom siv hluav taws xob sib txuas tsis zoo vim tias nws tsis tuaj yeem hloov pauv qhov kub siab. Nyob rau hauv luv luv, tus txheej txheem counterflow yog qhov opposite ntawm parallel flow process.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab cov khoom sib txuas ua ke ntawm cov khoom siv hluav taws xob sib txuas hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Counterflow vs Parallel Flow Heat Exchanger
Counterflow heat exchangers yog exchangers nyob rau hauv uas ob lub kua ntws nyob rau hauv parallel tab sis opposite cov lus qhia, hos ib tug parallel flow heat exchanger yog ib hom ntawm exchanger nyob rau hauv uas ob cov kua ntws mus rau hauv tib txoj kev. Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm cov khoom siv hluav taws xob sib txuas yog qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv yog qhov ua tau zoo vim tias nws tuaj yeem hloov pauv qhov siab tshaj plaws ntawm cov cua sov, qhov sib piv ntawm cov khoom siv hluav taws xob sib txuas tsis tshua muaj txiaj ntsig vim nws tsis tuaj yeem hloov pauv qhov kub siab.
