Flow Configuration ntawm Kub Exchangers
Countercurrent Flow:Nyob rau hauv countercurrent flow heat exchangers, cov txheej txheem thiab cov dej siv hluav taws xob ntws mus rau qhov sib txawv. Countercurrent flow in heat exchangers yog qhov ua tau zoo tshaj plaws thiab siv tau zoo tshaj plaws. Qhov sib txawv ntawm qhov kub thiab txias ntawm cov kua dej yog yuav luag khaws cia tsis tu ncua thoob plaws qhov ntev ntawm lub tshav kub exchanger. Qhov no muab qhov sib txawv ntawm cov cua sov hloov pauv ntau dua thiab txo cov kev ntxhov siab thermal. Nws kuj tseem ua tau rau cov kua dej txias kom muaj qhov hluav taws xob qhov hluav taws xob ze rau qhov inlet kub ntawm cov kua dej kub (qhov kub siab tshaj). Qhov kev teeb tsa no yuav tsum muaj thaj tsam tsawg dua piv rau nws qhov kev sib koom ua ke tam sim no.Co-tam sim no los yog Parallel Flow:Hauv co-tam sim no los yog sib npaug-kho cov cua kub sib txawv, cov txheej txheem thiab cov dej siv hluav taws xob ntws mus rau hauv cov lus qhia sib npaug. Nws yog qhov tsim nyog yog tias qhov hluav taws xob kub ntawm ob lub kua dej yog ze li qhov kub thiab txias. Qhov kub ntawm qhov sib txawv ntawm cov kua dej yog qhov loj heev ntawm qhov nkag thiab txo qis hauv qhov ntev ntawm cov khoom siv hluav taws xob sib txawv, uas ua rau muaj kev ntxhov siab loj heev thiab cov khoom siv thaum kawg. Qhov kev teeb tsa no muaj kev ua haujlwm tsawg dua piv rau cov dej ntws tawm.Hla Flow:Nyob rau hauv cross flow heat exchangers, cov txheej txheem thiab cov dej siv hluav taws xob ntws perpendicular rau ib leeg. Lawv feem ntau yog siv rau hauv cov tshuab nrog roj-kua lossis vapor-kua hluav taws kub pauv, qhov twg cov pa roj lossis vapor yog cov txheej txheem kua. Cov kua muaj nyob rau hauv ib lub raj thiab cov pa roj ntws tawm sab nraud cov hlab. Piv txwv ntawm kev sib hloov pauv hluav taws xob sib txawv yog cov cua condensers, radiators, thiab cua txias evaporator coils.
- Hybrid Flow:Hybrid flow heat exchangers yog tsim los ntawm cov tuam txhab tsim khoom los ua ke cov yam ntxwv ntawm cov lus hais saum toj no-hais txog kev khiav dej num. Piv txwv ntawm hybrid flow qauv yog plhaub-thiab-tube kub exchangers, cross flow-counter flow, thiab multi-pass flow heat exchangers.
