Qhov feem ntau ua rau boiling thiab overheating ntawm lub tsheb cav yog ib tug tsis txaus tus nqi ntawm antifreeze - coolant. Yog vim li cas rau qhov no tej zaum yuav yog ib lub qhov tsim nyob rau hauv lub radiator. Yog tias koj pom tias lub radiator depressurized, nws yuav tsum tau hloov. Txawm li cas los xij, txhawm rau txhim kho qhov teeb meem ib ntus, koj tuaj yeem siv txoj kev pheej yig dua thiab pheej yig dua, xws li soldering lub radiator.
Ua tsaug rau cov vuam zoo li no, koj tuaj yeem tsis tsuas yog tsav tsheb hauv tsev kom nyab xeeb (yog tias nws tshwm sim ntawm txoj kev), tab sis kuj tseem tsav tsheb rau qee lub sijhawm nrog cov tshuaj tiv thaiv kab mob ntxiv rau hauv txoj kev.
Yog li, cia peb saib yuav ua li cas lub tsheb radiators soldered.
Kev txiav txim hla qhov chaw
Nws feem ntau tshwm sim tias qhov xau tuaj yeem tsim tsis yog lub qhov (qhov) hauv lub cuab yeej, tab sis ntau yam microcracks, uas maj mam nthuav nrog cov cua sov ntawm cov hlau thiab tsim ib qho loj dua.thiab lub qhov loj. Raws li ib txwm muaj, nws yuav luag tsis pom qhov sib txawv ntawm lub tshuab hluav taws xob zoo li no, yog li, hauv qhov no, nws yog ib qho tsim nyog los tshem tawm ib feem thiab muffle tag nrho cov khoom tawm (tshwj tsis yog ib qho). Txuas lub compressor rau tom kawg (piv txwv li, uas yog siv los ua kom lub log tsheb) thiab, raws li qhia hauv daim duab hauv qab no, txo cov khoom rau hauv da dej.
Lub tshuab nqus tsev yuav tso cua, thiab tom qab ntawd nws yuav tawm ntawm microcracks hauv cov hlau, ua npuas me me. Feem ntau qhov no tshwm sim nyob rau hauv qhov chaw uas lub txhab nyiaj radiator yog crimped nrog lub raj thaiv. Tsis tas li ntawd, cov dej xau tuaj yeem pom tau vim muaj kev puas tsuaj rau cov khoom no. Visually, cov chaw zoo li no pom tau meej heev, lawv tuaj yeem txheeb xyuas qhov muag liab qab.
tooj liab heatsink soldered li cas?
Yog hais tias lub caij no yog ua los ntawm tooj liab, ces nws tuaj yeem soldered sai heev. Soldering yog ib txheej txheem ntawm kev ua hauj lwm nrog tsawg-melting solders, uas yuav siv sij hawm qhov chaw ntawm ib tug kub ntawm 300 mus rau 550 degrees Celsius. Cov cuab yeej tseem ceeb rau qhov no yog ib qho tshwj xeeb tooj liab soldering hlau nrog lub zog ntawm 250 watts lossis ntau dua. Nws yog ib nqi sau cia hais tias cov analogues uas siv nyob rau hauv lub neej txhua hnub tsis muaj lub hwj chim tsim nyog los tshem tawm qhov nyob rau hauv lub tsheb radiators.
Ntau zaus, ib qho tshwj xeeb tooj liab soldering hlau muaj lub taub tooj liab nrog lub peev xwm kub kub uas tuaj yeem ua kom sov nrog lub tshuab cua. Siv cov analogues hauv tsev, nws yuav luag tsis tuaj yeem kho lub tshuab hluav taws xob, vim tias qhov zoo ntawm kev sib txuas yuav tsis muaj kev ntseeg siab heev.
As withsiv 250W soldering hlau, koj tuaj yeem kho lub radiator hauv tsev
Ua ntej koj yuav tsum khaws cov khoom. Ntxiv nrog rau cov hlau nplaum uas muaj zog, koj yuav xav tau tin, soldering acid (piv txwv li, crushed rosin), ntawv xuab zeb thiab txhuam hlau. Nrog cov cuab yeej yooj yim no, lub tshuab hluav taws xob yog soldered hauv tsev.
Txhua txoj haujlwm los kho qhov nruj ntawm lub caij tuaj yeem muab faib ua ob peb theem:
- Ua ntej, thaj chaw puas ntawm lub tshuab hluav taws xob yog ntxuav nrog txhuam hlau thiab ntawv xuab zeb.
- Kev kho hluav taws xob ntxiv yog nrog los ntawm kev siv ob peb milliliters kua qaub rau saum npoo.
- Nrog kev pab ntawm cov hlau nplaum, qhov tawg yog rhuab thiab ntim nrog tin.
Qhov ntawd yog nws, ob peb vib nas this lub qhov hauv lub tshuab hluav taws xob yuav raug kho tiav. Cov tooj liab ntawm lub radiator yog zoo kawg nkaus soldered, yog li koj yuav tsum tsis txhob muaj teeb meem nrog vuam.
Nws tsim nyog sau cia tias yog tias lub raj dej txias tau pom hauv cov hlab, tom qab ntawd cov kev daws teeb meem uas tsim nyog tshaj plaws rau cov khoom siv kom muaj xau thiab tom qab ntim nws. Yog li, qhov ntws ntawm cov tshuaj tiv thaiv kab mob yog tshem tawm tag nrho. Nyob rau tib lub sijhawm, tsis txhob hnov qab tias lub raj no yuav tsis tuaj yeem, thiab qhov no yuav tshwm sim ntawm cov cua kub dissipation los ntawm radiator. Radiator soldering nyob rau hauv qhov chaw no tsuas yog siv rau cov ntsiab ntawm txoj kab uas hla me me, nrog rau cov khoom uas tsis nqa cov khoom siv kho tshuab.
Qhov twg yuav tsum tsis siv?
Txoj kev kho noyuav tsis daws qhov teeb meem nrog kev xau yog tias qhov sib txawv tau pom hauv cov fittings, nrog rau cov khoom siv hluav taws xob loj heev. Xws li soldering ntawm lub radiator yuav tsuas powerless. Hauv qhov no, tib txoj kev daws teeb meem yog yuav thiab nruab ib lub cuab yeej tooj liab tshiab. Txawm li cas los xij, muaj ib txoj hauv kev uas koj tuaj yeem rov qab kho lub Hoobkas tsis muaj (tightness) ntawm qhov haum los ntawm kev siv cov txheej tooj liab rau ntawm nws qhov chaw.
Brazing yog lwm txoj hauv kev yuav cov radiators tshiab
Cov chaw pabcuam kws tshaj lij muab cov neeg tsav tsheb nrog kev pabcuam xws li kho lub tshuab hluav taws xob brazing. Qhov no txoj kev ntawm soldering yuav tsum tau siv tshwj xeeb tooj liab carbide solders ntawm cov khoom tshwj xeeb. Cov txheej txheem kho yog nqa tawm ntawm qhov kub ntawm 500 txog 1000 degrees Celsius. Raws li kev ntseeg tau, qhov zoo ntawm kev sib txuas ntawm no xyaum tsis txawv ntawm lub Hoobkas.
Brazing yog ua los ntawm kev siv tooj liab solder rau qhov chaw puas hauv qhov chaw borax. Cov khoom kawg tiv thaiv cov hlau los ntawm oxidation, uas lav qhov zoo thiab nruj kev sib txuas ntawm qhov chaw.
Aluminium heatsink soldered li cas?
Yog tias pom ib lub qhov nyob hauv lub raj ntawm lub cuab yeej, ces qhov no tsuas yog soldering tuaj yeem rov ua kom nruj ntawm qhov. Ua hauj lwm nrog cov khoom siv txhuas yog qhov zoo tshaj plaws nrog cov khoom tshwj xeeb (xws li cov siv los kho cov tub yees).
Cold Weld Kho
Yog tias cov yas muaj nyob hauv koj lub tshuab hluav taws xob, thaum kho nws, koj tsuas tuaj yeem ua tsis tauua yam tsis muaj vuam txias. Lub ntsiab lus ntawm cov txheej txheem no yog los kho qhov nruj ntawm lub cuab yeej siv ob lub ntsiab lus epoxy-raws li nplaum nplaum. Yuav siv cov vuam txias li cas kom raug? Ua ntej tshaj plaws, koj yuav tsum tau kho qhov chaw puas nrog cawv lossis roj av kom degrease nws. Tom qab ntawd koj tsis tuaj yeem tos kom txog thaum lub tshuab hluav taws xob txias (yog tias lub cav kub), tab sis tam sim ntawd pib vuam.
Nyob rau hauv chav kawm ntawm kev ua haujlwm, nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas cov cuab yeej siv tau zoo rau kev siv cov kua nplaum. Tsis zoo li cov xwm txheej dhau los, lub tshuab hluav taws xob tom qab kho tsis tuaj yeem ua haujlwm tam sim ntawd. Cov lus qhia hais tias tom qab siv cov vuam txias, nws yuav tsum tau tos kom txog thaum cov khoom tau qhuav thiab tawv. Qhov kev kho tshuab no tsis siv ntau zaus, thiab tag nrho vim tias hom kev vuam no tsuas yog ua rau cov txiaj ntsig tau ib ntus, uas yog, tom qab ob peb lub lis piam, lub tsheb yuav rov ua kom tsis muaj zog. Txawm hais tias ntawm txoj kev no txoj kev pab tau zoo heev.
Argon vuam
Cov kev sib txuas ntawm lub tsheb radiators tso cai rau koj los kho lub tank nkaus xwb ntawm lub tshuab hluav taws xob nrog cov phab ntsa tuab. Thiab yog hais tias koj honeycomb tawg, ces nws yuav luag tsis yooj yim sua kom brew nws nrog argon. Yog li ntawd, ib qho arc yuav tawg los ntawm nws, thiab lub qhov tsuas yog nthuav me ntsis raws li qhov kub thiab txias. Aluminium vuam siv nyob rau ntawm qhov kub ntawm txog 1000 degrees Celsius los yog ntau tshaj nyob rau hauv ib puag ncig tiv thaiv roj - argon (yog vim li cas nws lub npe yog argon vuam).
Vim li cas txoj kev no tsis siv davcov neeg tsav tsheb? Tag nrho cov ntsiab lus tsis yog txawm tias argon vuam tsuas yog kho qhov nyob ib puag ncig los ntawm cov phab ntsa tuab tuab, tab sis kev ua haujlwm nrog argon yuav tsum muaj kev paub ntau thiab kev txawj ntse. Qhov no ua rau muaj laj thawj los faib cov kev kho xws li kev tshaj lij.
Yog li, peb tau pom yuav ua li cas solder lub tshuab hluav taws xob nrog peb tus kheej tes, thiab siv txoj kev vuam zoo li cas.
