Lub hauv paus ntsiab lus ua haujlwm ntawm lub phaj kub exchanger yog dab tsi?

Kev khiav dej num ntawm lub phaj warmth exchanger revolves hla lub ntsuab hloov ntawm warmth ntawm cov kua uas tsis pub lawv sib tov. Ntawm no yog ib kauj ruam-nrog kev pab ntawm kev siv-kauj ruam rationalization ntawm txoj kev nws ua hauj lwm:
Plate Stack Assembly: Ib lub phaj sov so exchanger muaj xws li ib ntus ntawm nyias, corrugated hlau daim hlau, feem ntau yog fabricated los ntawm stainless hlau, titanium, los yog lwm yam corrosion-resistant khoom. Cov phiaj no tau teeb tsa nyob rau hauv ib qho kev sib txuas thiab hloov pauv, tsim kev sib cais ntab rau cov kua dej. Cov phiajcim tau muab khi puag ncig lub rims nrog kev pab los ntawm kev siv gaskets los yog 焊接 (welded) kom zoo raws li phau ntawv cov kua.
Fluid Distribution: Cov kua dej nkag mus rau qhov sov so exchanger ntawm cov inlet ports cais. Ib cov kua dej ntws los ntawm cov channel zoo li ntawm txhua lub phaj sib txawv (tus naj npawb ib lub voj voog), txawm tias cov kua dej sib txawv ntws los ntawm cov kab sib txuas ntawm cov kab sib txuas (qhov thib ob Circuit Court). Qhov kev teeb tsa no tau lees paub tias cov kua dej sib cais nrog kev pab ntawm kev siv cov phaj thiab tsis muaj txoj hauv kev los rau hauv kev sib cuag ncaj qha.
Thaum tshav kub kub hloov pauv: Raws li cov kua dej tsis ntev los no ntws los ntawm nws cov channel, nws hloov qhov sov sov los ntawm cov hlau nplaum tawv nqaij mus rau cov kua dej uas tsis muaj ntshav ntws hauv cov kab sib txuas. Cov qauv corrugated ntawm daim hlau yuav ua rau muaj kev kub ntxhov ntawm cov kua dej, txo qhov tuab ntawm cov ciam teb txheej thiab txhim kho kev ua haujlwm sov so.
Counter-Current lossis Co-Current Flow: Nyob ntawm qhov teeb tsa, cov kua dej tuaj yeem ntab hauv ob qho tib si counter-modern lossis co-modern qauv. Counter-modern ntab, uas feem ntau mus txog hnub tim ib feem ntawm qhov kev txav tsis ntev los no tau ntsib qhov txias tshaj plaws ntawm qhov tsis muaj ntshav txav, yog qhov siab tshaj plaws ntsuab teeb tsa rau kev hloov pauv sov.
Kev Tswj Kev Kub Kub: Qhov kub ntawm cov kua dej tawm ntawm qhov sib hloov sov yog tswj nrog kev pab los ntawm kev siv kho cov ntab ntab, ntau yam ntawm cov phaj siv, lossis qhov kub sib txawv ntawm cov kua dej. Nyob rau hauv ob peb daim ntawv thov, li qub los yog manipulate qauv yog siv los tswj cov tsis.
Tawm thiab rov ua dua: Thaum qhov hloov pauv qhov sov sov tau tshwm sim, cov kua dej txias lossis cov cua sov tawm mus rau qhov chaw sov so los ntawm cov qhov hluav taws xob sib cais thiab raug xa rov qab mus rau hauv cov txheej txheem lossis mus rau lawv qhov chaw tom ntej.
Kev tu thiab tu: Cov phaj feem pua ​​​​ntawm cov phaj tuaj yeem raug tshem tawm rau kev ntxuav thiab tu, suav nrog kev tshem tawm cov khoom tso lossis fouling uas yuav txo qis kev ua haujlwm ntawm lub sijhawm. Qhov no yog qhov txiaj ntsig loj tshaj li ob peb qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv warmth exchanger designs.
Nyob rau hauv cov ntsiab lus, lub phaj warmth exchanger enables hloov ntawm warmth ntawm cov kua nrog kev pab los ntawm kev siv ib tug sib lawv liag ntawm nyias, thermally conductive daim hlau uas cais cov kua txawm li tso cai rau sov so los ntawm ib tug mus rau qhov opposite. Cov layout txhawb kev ua haujlwm ntau dhau thiab hloov tau rau ntau hom kev lag luam thiab kev lag luam.
