Txhawm rau txhim kho corrosion kuj ntawm cov tub yees evaporator hauv lithium bromide hauv nruab nrab cua txias system, titanium raj yog siv los hloov lub raj tooj liab, thiab lub raj elliptical tau npaj los hloov lub raj raj los txhim kho cov evaporation efficiency ntawm refrigerant sab nraum titanium. cev.
Nyob rau hauv lub lithium bromide nqus tub yees system, LiBr-H2O tov yog heev corrosive rau stainless hlau, tooj liab, thiab tooj liab alloys, uas ncaj qha cuam tshuam rau lub neej kev pab cuam ntawm lub tub yees system thiab degrades lub system kev ua tau zoo. Titanium alloy tau dhau los ua qhov kev xaiv zoo los hloov cov tooj liab alloy hauv kev tsim cov khoom siv hluav taws xob vim nws cov corrosion kuj zoo heev, tsis tshua muaj siab, thiab siab hardness. Txawm li cas los xij, qhov thermal conductivity ntawm titanium tsuas yog 18.7 W · m-2 · K-1, uas yog qis dua li ntawm tooj liab 401 W · m-2 · K-1 . Yog li ntawd, nws yog ib qho tseem ceeb heev los kawm txog tus cwj pwm khiav thiab cov yam ntxwv ntawm cov cua kub hloov pauv ntawm cov yeeb yaj kiab ua kua sab nraum lub titanium raj thiab txhim kho kev ua haujlwm siab ntawm titanium tshav kub exchanger raj nyob rau hauv cov nqe lus ntawm anti-corrosion ntawm tshav kub exchanger raj.
Piv nrog rau lub raj puag ncig, lub raj tsis yog lub voj voog muaj cov yeeb yaj kiab zoo dua thiab cov yam ntxwv hloov pauv kub, thiab lub raj elliptical muaj qhov zoo dua. Txoj kev tsom xam ntawm cov txheej txheem ua kua zaj duab xis kub hloov pauv qhia tau hais tias ua kom cov elliptical coefficient ntawm txoj kab rov tav tuaj yeem txhim kho tag nrho cov cua sov hloov coefficient. Nyob rau hauv qhov ntau ntawm ellipticity coefficient E=1.0~ 1.7, nrog qhov nce ntawm E, qhov nruab nrab thickness ntawm cov kua zaj duab xis sab nraum lub raj txo, qhov ceev ntawm cov kua zaj duab xis nce, lub drywall cheeb tsam txo. , thiab cov tshav kub hloov pauv ciam txheej yog nyias, yog li cov nyhuv hloov hluav taws xob tau zoo dua qub. Elliptical tubes muaj qhov zoo dua cov cua sov hloov mus.
