(3) Kev siv cov roj yaj qes qis thiab cov organic flux los ua cov tooj liab kub kub, kev siv cov pa hluav taws xob ua kom zoo (N2) kev tiv thaiv cov txheej txheem txhawm rau txhawm rau txhim kho cov khoom lag luam ntawm txhuas lub tshuab hluav taws xob , yog yav tom ntej kev txhim kho. Kev siv cov xim daj hluav taws xob rau lub tsheb thiab qee lub tsheb me me yog qhov kev txhim kho tshiab. Txhuas raws li tooj liab tuaj yeem txuas ntxiv qhov hnyav ntawm qhov hluav taws xob. Hauv tshwj xeeb, txhuas hluav taws xob kub tsim los ntawm kev zawm hluav taws tuaj yeem ua tiav tib lub zog ntawm tag nrho cov kev sib dhos, yog li txhim kho kev ntseeg tau ntawm lub dab dej tso cua sov.
(4) Kev sib sau ua ke aluminium kub dab dej tau siv dav hauv Tebchaws Europe. Kev sib dhos aluminium kub dab dej yog txheej txheem siv los txo cov pa phem los ntawm cov txheej txheem brazing thiab txo qhov vuam nyuaj ntawm cov khoom siv aluminium. Txawm hais tias qee qhov ntawm cov khoom lag luam tseem siv cov qauv no, cua tiv thaiv yuav cuam tshuam rau kev siv tus qauv. Cov qauv zoo tshaj plaws: tub ntxhais radiator yog lub txhuas tub ntxhais los yog tooj liab tsim los ntawm txoj kev vuam; qhov tseem ceeb; chav dej dej yog txhawb nqa nylon casting; cov kais dej thiab cov tub ntxhais tseem nias tawm tsam cov tub ntxhais los ntawm ntug ntawm cov ntawv tseem ceeb. Ntawm qhov txheej txheem ntawm lub chamber, lub ntsaws ruaj ruaj ntawm cov roj hmab sib xyaw ntawm qhov loj thiab qhov sib txuas ntawm cov qhov dej ntawm chav dej yog compressed thiab deformed, yog li ob leeg tau ruaj khov thiab txuas.
Cov dab dej kub ua ke yog siv dav hauv Tebchaws Europe. Feem ntau los ntawm kev pom ntawm kev tiv thaiv ib puag ncig. Cia siab tias lub welded aluminium tub ntxhais los yog tooj liab tub ntxhais lub cev yuav siv dav yav tom ntej, thiab chav dej yog tooj liab-yas sib txuas lossis txhuas-yas sib xyaw ua ke kub dab dej rau casting nylon. Cov kev taw qhia ntws ntawm lub coolant ntawm xws li lub tshuab hluav taws xob feem ntau yog hom khaub lig ntws uas qhov kev taw qhia rau sab laug thiab sab xis ntws. Muaj feem tsawg tsawg ntws los ntawm hauv txoj kev qhia ntsug sib haum rau tus ntoo khaub lig ntws yam.
