Saib xyuas qhov kub ntawm sab nrauv hloov ua ntej thiab tom qab kev hloov pauv
Xaiv qee cov ntsiab lus saib xyuas kom txuag hluav taws xob Thermal rwb thaiv tsev kev hloov pauv ntawm cov khoom siv thermal thiab cov kav dej, thiab ntsuas qhov kub ntawm sab nrauv ntawm cov ntsiab lus saib xyuas ua ntej thiab tom qab kev hloov pauv. Tom qab ua tiav cov rwb thaiv tsev thiab kev txuag hluav taws xob hloov pauv, qhov zoo li qhov kub thiab txias ntawm cov cuab yeej ua tau raws li cov qauv tsim nyog, thiab cov khoom siv hluav taws xob thiab hluav taws xob txuag hluav taws xob ntawm cov khoom siv hluav taws xob thiab cov kav dej tau raug kho kom zoo dua kom ua tiav cov txheej txheem rwb thaiv tsev thiab txuag hluav taws xob.

Ua ntej lub kaw-off valve tsis yog rwb thaiv tsev, qhov kub ntawm qhov chaw yog 371 Fahrenheit, uas yog sib npaug rau 188.44 Celsius, raws li pom los ntawm cov duab.

Tom qab lub kaw-off valve tau insulated thiab ua haujlwm rau 10 hnub, qhov kub ntawm qhov chaw yog 119 Fahrenheit, uas yog sib npaug rau 48.3 Celsius, raws li pom los ntawm cov duab.

Kev sib piv ntawm qhov kub poob ua ntej thiab tom qab hloov kho
Kev siv q (W / m2) qhia tau hais tias qhov kub ntawm qhov kub thiab txias, qhov nyiaj ntawm cov cua kub dissipation tsim los ntawm cheeb tsam yog qhov kub thiab txias ntawm qhov khoom, thiab thaj tsam ntawm cov thermal rwb thaiv tsev muaj kev sib raug zoo nrog kev tshawb nrhiav cov khoom siv thermal thiab cov kav dej thermal rwb thaiv tsev, qhov Performance index yog qhov taw qhia tseem ceeb ntawm kev soj ntsuam cov khoom siv thermal thiab cov kav dej. Nws muab tus nqi siab tshaj plaws ntawm kev poob cua sov tso cai rau cov khoom siv thermal thiab cov kav dej hauv qab qhov sib txawv nruab nrab kub.
q=a×(TW-TF)
q qhia qhov kub poob / kub txaus ntom ntom, (W / m2) cylindrical phab ntsa pipeline nto tshav kub hloov qhov system a = 9.42 + 0.05 × (TW-TF) W / (m2-K); TW qhia qhov kub ntawm sab nrauv ntawm lub Rwb thaiv tsev Sqauv; TF qhia qhov kub thiab txias.

Tom qab kev txhim kho lub tes tsho rwb thaiv tsev, qhov kub thiab txias hloov ntawm cov khoom feem ntau yuav qeeb, uas tau qhia hauv cov xwm txheej hauv qab no:
Rau cov khoom kub kub: xws li cov khoom siv ua haujlwm, cov kav dej kub kub, thiab lwm yam. Thermal rwb thaiv tsev lub tes tsho tuaj yeem txo qhov kub poob mus rau ib puag ncig ib puag ncig. Vim tias lub tes tsho thermal rwb thaiv tsev muaj cov thermal conductivity tsawg, tuaj yeem cuam tshuam cov cua sov los ntawm kev ua thiab convection mus rau lub ntiaj teb sab nraud, kom cov khoom kub poob qis qis qis, thiaj li tswj tau qhov kub siab dua, txo qis cua sov, thiab txhim kho kev siv hluav taws xob.
Rau cov khoom uas tsis muaj qhov kub thiab txias: zoo li cov khoom siv cua kub qis, cov saw txias thauj khoom, thiab lwm yam. Rwb thaiv tsev Jacket tuaj yeem tiv thaiv kev hloov mus rau sab nraud. Qhov no tuaj yeem ua rau cov khoom kub tsis tshua muaj kub, txo qhov poob ntawm qhov txias, thiab tiv thaiv lawv qhov kub thiab txias los ntawm kev nce siab sai heev thiab cuam tshuam rau cov khoom zoo, piv txwv li, tiv thaiv cov khoom noj hauv cov kab mob khaub thuas los ntawm kev puas tsuaj vim qhov kub thiab txias.
Rau cov khoom lossis ib puag ncig uas qhov kub thiab txias yuav tsum tau ua kom ruaj khov: piv txwv li, qee cov khoom siv hauv chav kuaj thiab cov cuab yeej hluav taws xob uas muaj qhov yuav tsum tau muaj rau qhov kub thiab txias, lub tsho thermal rwb thaiv tsev yuav pab tswj kev ruaj ntseg ntawm nws qhov kub thiab txias. Nws tuaj yeem txo qhov cuam tshuam ntawm kev hloov pauv ntawm ib puag ncig ib puag ncig ntawm cov khoom, kom qhov kub thiab txias ntawm cov khoom nyob rau hauv ib qho kev tswj kom muaj qhov tsis tu ncua, hauv kev pom zoo ntawm kev ua haujlwm ib txwm muaj ntawm cov khoom siv thiab qhov tseeb ntawm qhov kev sim.
