Lub tshav kub hloov efficiency ntawmPhaj Thaum tshav kub kub ExchangersNws yog qhov zoo tshaj plaws ntawm cov khoom siv hluav taws xob sib txawv, feem ntau yog vim qhov kev tsim qauv zoo nkauj thiab cov qauv hloov hluav taws xob. Cov cuab yeej siv no siv cov qauv txheej txheej ntawm ntau cov hlau nyias hlau hloov cov phaj, nrog cov qauv corrugated stamped rau ntawm cov phaj phaj. Cov corrugations no zoo heev ua rau thaj chaw hloov cua sov- nrog rau thaj chaw tshwj xeeb (tshav kub hloov chaw hauv ib chav tsev ntim) 2-5 npaug ntawm lub plhaub- thiab- raj cua kub exchangers- kom muaj kev sib cuag ntawm cov xov xwm kub thiab txias.
Qhov sib nrug ntawm cov hlau hloov hluav taws xob yog me me (feem ntau tsuas yog 2-5 millimeters), yuam cov xov xwm kom ntws ntawm qhov siab tshaj plaws hauv lub xeev turbulent. Qhov no txo cov thickness ntawm lub tshav kub hloov chaw ciam teb txheej, tiv thaiv cov tsim ntawm stagnant khaubncaws sab nraud povtseg ntawm tshav kub exchanger chaw, thiab accelerates tshav kub hloov lwm lub tsev. Lub caij no, cov qauv corrugated ua rau muaj zog turbulence nyob rau hauv cov xov xwm ntws, ntxiv cuam tshuam rau ciam teb txheej thiab txhim kho cov cua sov ua haujlwm.
Tsis tas li ntawd, cov phiajcim yog ua los ntawm cov khoom siv thermal conductivity siab (xws li stainless hlau thiab titanium alloy), ua kom cov cua sov hloov mus sai los ntawm cov phaj thiab txo cov thermal tsis kam. Cov xov xwm kub thiab txias ntws nyob rau hauv cov lus taw qhia ntawm ob sab ntawm daim hlau, tsim cov hluav taws xob sib hloov hluav taws xob uas ua rau qhov kub thiab txias sib txawv gradient thiab ua kom muaj kev hloov pauv mus tas li.
Kev sib koom ua ke ntawm cov qauv tsim thiab cov txheej txheem tsim ua rau lub tshav kub hloov coefficient ntawm Plate Heat Exchangers ntau dua li cov khoom siv ib txwm muaj. Rau tib qhov kev hloov pauv cua sov, nws muab cov hneev taw me me thiab siv hluav taws xob qis dua, ua rau nws muaj - kev xaiv ua tau zoo rau cov xwm txheej kev lag luam kub pauv.
