Lub plhaub -thiab- raj kub exchanger yog dab tsi?
Apr 07, 2026| Plhaub-thiab-tube heat exchangers yog dav siv cov khoom siv hluav taws xob sib pauv hauv tshuaj, roj av, tub yees, thiab fais fab kev lag luam. Lawv cov khoom tseem ceeb muaj xws li lub plhaub, lub hnab ntim khoom, thiab lub kaus mom kawg. Lub hauv paus ntsiab lus ntawm kev ua haujlwm feem ntau cuam tshuam nrog kev sib pauv cua sov ntawm ob qhov sib txawv ntawm kev tshaj tawm los ntawm kev sib txuas thiab kev sib txuas.
Tshwj xeeb, ib qho nruab nrab ntws hauv cov raj ( raj- sab nruab nrab), thiab lwm qhov ntws hauv lub plhaub - sab chaw (plhaub - sab nruab nrab). Thaum tshav kub kub pauv tshwm sim ntawm ob qho tib si los ntawm cov phab ntsa, ua tiav qhov txias lossis cua sov. Plhaub-thiab-tube heat exchangers tuaj nyob rau hauv ntau yam qauv, feem ntau ruaj tubesheet, floating taub hau, thiab U-tube bundle hom. Qhov kev xaiv yog nyob ntawm cov yam ntxwv xws li kev ua haujlwm, cov yam ntxwv nruab nrab, thiab xav tau kev hloov hluav taws xob hloov hluav taws xob.
Cov khoom siv hluav taws xob no muaj qhov zoo xws li cov qauv yooj yim, kev ua haujlwm siab ua haujlwm yooj yim, thiab muaj zog yoog raws. Tsis tas li ntawd, lawv muaj kev ua haujlwm siab thermal, kev ua haujlwm zoo ntawm cov cua sov, thiab kev yoog raws rau ntau yam kev ua haujlwm, ua rau lawv siv dav hauv ntau qhov chaw. Ib txhij, lawv tsim thiab tsim khoom yuav tsum nruj me ntsis ua raws li cov qauv thiab cov kev qhia tshwj xeeb kom ntseeg tau tias lawv cov kev ua tau zoo thiab kev nyab xeeb.
