du tube VS Finned tube kub exchanger
Thaum nws los txog rau cov khoom siv hluav taws xob, muaj ob hom: finned tube heat exchangers thiab heat exchangers with straight tubes. Tus qub kuj tseem hu ua "surface exchanger," thaum lub tom kawg yog hu ua "plhaub thiab tube exchanger."
Finned Tube Thaum tshav kub kub Exchangers
Finned tube heat exchangers yog ib hom kev sib hloov ntawm qhov chaw uas ib qho dej ntws tawm sab nrauv ntawm cov raj ncig thaum lwm cov dej ntws los ntawm cov hlab. Cov hlab no muaj ntau cov fins txuas rau lawv, uas ua haujlwm kom nce qhov chaw.
Finned tubes yog qhov zoo tagnrho rau siv nyob rau hauv ib puag ncig uas muaj qhov txwv tsis pub muaj rau cov khoom siv hluav taws xob. Lawv kuj feem ntau siv rau hauv kev siv yuam-convection vim tias cov fins qiv lawv tus kheej kom zoo dua cov cua sov. Cov khoom siv hluav taws xob no tshwj xeeb tshaj yog cov cua sov dissipating, uas ua rau lawv zoo rau kev siv hauv cov cua txias cua sov.
smooth Tube Thaum tshav kub kub Exchangers
Smooth tube heat exchangers, tseem hu ua "bare tube" heat exchangers, yog lwm hom plhaub thiab raj kub exchanger. Lawv hu ua cov raj du vim tias lawv tau ua kom zoo rau kev hloov cov cua sov yam tsis muaj kev poob siab. Lawv yog tsim los ntawm cov khoom sib zog xws li txhuas thiab nyias dua li lwm lub teeb lub teeb.
Smooth tube heat exchangers yog siv rau ntau lub hom phiaj tshaj li finned tube exchangers. Lawv tsim nyog rau cov ntawv thov uas qhov kev txhawj xeeb tseem ceeb yog zam kom tsis txhob muaj kab mob. Piv txwv li, lawv tau siv rau hauv kev siv tshuaj, chaw ua zaub mov, thiab chaw ua dej huv. Lub teeb raj kuj yog qhov zoo tagnrho rau cov khoom siv hluav taws xob uas yuav tsum tau ua haujlwm ntawm qhov kub thiab txias lossis xav tau ua cov dej kub hloov pauv huab cua.
Hauv kev xaus, ob qho tib si finned tube thiab lub teeb lub raj cua kub exchangers muaj lawv cov txiaj ntsig thiab qhov tsis zoo. Finned tube heat exchangers yog qhov zoo tagnrho rau cov cheeb tsam uas qhov chaw nyob ntawm tus nqi qis lossis qhov uas yuav tsum tau muaj kev quab yuam-convection. Lub teeb raj, ntawm qhov tod tes, yog qhov zoo tshaj plaws rau cov ntawv thov uas qhov kev huv huv yog qhov tseem ceeb thiab qhov uas yuav tsum tau hloov cov cua kub kub. Kev nkag siab qhov sib txawv ntawm ob hom kev sib hloov hluav taws xob tuaj yeem pab cov lag luam xaiv cov khoom siv hluav taws xob tsim nyog rau lawv cov kev xav tau tshwj xeeb.
