Feem ntau, phaj kub exchangers raug faib feem ntau raws li lawv cov qauv, uas yog, lawv cov duab. Lawv tuaj yeem muab faib ua plaub yam tseem ceeb: ① Detachable phaj kub exchangers (tseem hu ua gasketed phaj kub exchangers), ② Welded phaj kub exchangers, ③ Kauv phaj kub exchangers, thiab ④ phaj- dov kub exchangers (tseem hu ua honeycomb heat exchangers).
Welded phaj kub exchangers tau muab faib mus rau hauv: semi-welded phaj kub exchangers, tag nrho welded phaj kub exchangers, phaj- plhaub kub exchangers, thiab brazed phaj kub exchangers.
Lwm yam kev faib ua feem siv muaj xws li:
1. Raws li qhov chaw sib pauv cua sov hauv ib chav tsev, cov phaj kub hloov pauv tau suav tias yog cov khoom siv hluav taws xob sib txuas, feem ntau piv rau lub plhaub - thiab - raj kub exchangers, uas feem ntau nyob hauv cheeb tsam loj.
2. Raws li cov txheej txheem thov, phaj kub exchangers muaj ntau lub npe: phaj rhaub, phaj txias, phaj condensers, phaj preheaters;
3. Raws li kev sib xyaw ua ke, lawv tau muab faib ua ib qho - kis phaj kub exchangers thiab ntau - kis phaj kub exchangers;
4. Raws li kev khiav dej num ntawm ob lub xov xwm, lawv tau muab faib ua co-tam sim no (parallel flow) phaj kub exchangers, counter-tam sim no phaj kub exchangers, thiab cross-flow (cross-flow) phaj kub exchangers, nrog rau ob tom kawg yog siv ntau dua;
5. Raws li qhov sib txawv loj ntawm cov dej ntws, lawv tau muab faib ua cov pa sib txawv ntawm cov phaj kub sib txawv thiab cov sib txawv dav phaj kub exchangers;
6. Raws li corrugation, phaj kub exchangers muaj cov ncauj lus kom ntxaws sib txawv, uas yuav tsis tau piav qhia ntawm no. Thov xa mus rau: Plate Heat Exchanger Plate Corrugation Forms.
7. Raws li seb lawv puas yog cov khoom tiav, lawv tuaj yeem muab faib ua ib qho -unit phaj kub exchangers thiab phaj kub exchanger units.
