Lub plhaub-thiab- raj cua kub exchanger muaj lub plhaub, lub raj xa hluav taws xob, cov ntawv raj, baffles, thiab lub thawv tube. Lub plhaub feem ntau yog cylindrical, muaj lub raj ntim, nrog rau ob qhov kawg tsau rau daim ntawv raj. Ob cov kua dej sib pauv cua sov yog hu ua tube-sab kua thiab plhaub-sab kua; ib tug ntws hauv cov hlab ntsha. Txhawm rau txhim kho cov cua sov hloov coefficient ntawm cov kua dej tawm sab nraud, ob peb baffles feem ntau yog ntsia hauv lub plhaub. Cov baffles no nce qhov nrawm ntawm lub plhaub- cov kua dej sab, yuam kom nws hla lub raj ntim tom qab ntau zaus raws li txoj hauv kev tau npaj tseg, yog li ua kom muaj kev kub ntxhov. Cov raj xa hluav taws xob tuaj yeem muab tso rau hauv daim duab peb sab sib npaug lossis ib lub xwmfab ntawm daim ntawv raj. Ib qho kev sib npaug ntawm daim duab peb sab yog ntau dua, ua rau muaj kev kub ntxhov ntau dua thiab qhov sib txawv ntawm cov cua sov loj dua; ib qho kev npaj square ua kom yooj yim ntxuav ntawm sab nraud ntawm cov hlab ntsha thiab tsim nyog rau cov kua dej uas ua rau cov nplais.
Cov kev tswj tseem ceeb ntawm lub plhaub-thiab- raj kub exchanger yog qhov chaw cua sov, cov dej kub ntws, qhov muaj peev xwm hloov hluav taws xob, thiab qhov ntsuas kub nruab nrab.
Ib qho dhau ntawm cov kua los ntawm lub raj ntim yog hu ua ib lub raj hla; ib tug hla lub plhaub hu ua ib lub plhaub hla. Daim duab qhia pom qhov yooj yim tshaj plaws ib zaug - plhaub- dhau, ib zaug - raj- kis tau tus kub exchanger, feem ntau abbreviated li 1-1 hom kub exchanger. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Nyob rau hauv txoj kev no, cov kua dej tsuas yog dhau los ntawm ib feem ntawm cov hlab ntsha ntawm ib lub sijhawm, yog li hla lub raj ntim ntau zaus; qhov no hu ua multi-tube pass. Ib yam li ntawd, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov qhov no yog hu ua multi-shell pass. Multi-tube pass thiab multi-plhaub pass tshav kub exchangers tuaj yeem siv ua ke.
