Welding Heat Sink yog dab tsi thiab nws cov txheej txheem?

Vuam kub dab dej yog cov khoom cua kub dissipation uas tsim los ntawm cov txheej txheem vuam ua cov txheej txheem tseem ceeb.

 

 

Tom qab ntau tshaj kaum xyoo ntawm txoj kev loj hlob, soldering cua sov dab dej tau tsim los ntawm cov brazing thaum ntxov raws li cov txheej txheem tseem ceeb rau tam sim no soldering raws li cov txheej txheem tseem ceeb ntawm hom dab dej kub no. Soldering kuj yog ib txwm hu ua soldering. Nyob rau hauv cov nqe lus ntawm kev siv tshuab, hom welded cua sov dab dej ua ke ua ke hauv qab phaj thiab fins ntawm lub dab dej kub ua ke los ntawm vuam. Cov txheej txheem soldering yog dav siv, tsuav yog qhov saum npoo tuaj yeem kho rau solderability thiab tuaj yeem tiv taus qhov kub thiab txias, nws tuaj yeem raug soldered. Cov khoom siv feem ntau siv rau vuam kub dab dej feem ntau yog tooj liab thiab txhuas. Xav txog cov nqi, cov qauv, kev ua haujlwm, kev hloov hluav taws xob thiab cov nqi, tooj liab thiab txhuas yog siv dav tshaj plaws.

 

Los ntawm cov phaj hauv qab thiab cov fins ntawm vuam kub dab dej, ua ke nrog ob feem ntau siv cov ntaub ntawv ntawm tooj liab thiab txhuas, raws li txoj kev vuam ua ke, nws tuaj yeem muab faib ua plaub pawg hauv qab no:

 

Thawj qeb, aluminium fins ntxiv rau txhuas hauv qab phaj yog welded ua ke los tsim ib qho txhuas-welded cua sov dab dej. All-aluminium welded cua sov dab dej muaj ob peb yam ntxwv:
(1) High ceev ntawm iav fins;
(2) Qhov hnyav ntawm lub dab dej kub lub teeb. Tsis tas li ntawd, nws cov nyhuv thermal dissipation kuj tau txhim kho, vim hais tias cov cua kub dissipation nyhuv ntawm lub dab dej kub yog proportional rau lub tshav kub dissipation cheeb tsam nyob rau hauv tej yam kev mob ua hauj lwm. Qhov loj dua qhov kub dissipation cheeb tsam, qhov zoo dua qhov kub dissipation nyhuv. Yog li ntawd, qhov ntom ntawm cov hniav nyiaj hniav kub nce, yog li ua kom lub tshav kub dissipation cheeb tsam, yog li ntawd nws cov cua kub dissipation nyhuv yog zoo dua.

 

 

 

Qhov thib ob, tooj liab puag phaj ntxiv rau tooj liab fins welded ua ke tuaj yeem tsim ib lub dab dej ntshiab tooj liab. Lub thermal conductivity K tus nqi ntawm tooj liab yog ntau tshaj li ob zaug ntawm txhuas, yog li nws cov kev hloov pauv kub yuav zoo dua. Nyob rau hauv cov teeb meem kub dissipation uas nyuaj los daws nrog txhuas, koj tuaj yeem xaiv siv tooj liab los daws nws. Txawm li cas los xij, cov khoom siv tooj liab ntshiab muaj qee qhov tsis zoo. Piv txwv li, lub hardness ntawm tooj liab kuj tsis tshua muaj, qhov hnyav ntawm tooj liab kuj hnyav, qhov ceev yog ntau tshaj ob zaug ntawm txhuas, thiab tus nqi yog ntau tshaj li ob zaug ntawm txhuas.

 

 

Qhov thib peb qeb, aluminium fins ntxiv rau tooj liab hauv qab phaj tuaj yeem welded rau hauv lub welded kub dab dej nrog tooj liab hauv qab phaj thiab txhuas hniav fins. Tus yam ntxwv ntawm hom dab dej kub no yog tias nws yuav siv sij hawm rau hauv tus account qhov zoo ntawm cov cua sov hloov thiab kub uniformity ntawm tooj liab thiab qhov hnyav ntawm txhuas yog lub teeb, thiab tus nqi kuj tsawg. Tsawg zog, zoo dua kev sib txuas.

 

 

Qib plaub siv aluminium hauv qab phaj ntxiv rau tooj liab fins, uas tuaj yeem daws qhov teeb meem ntawm kev ua haujlwm zoo rau hauv pem teb, thiab cov khoom tiav muaj cov qauv tsim muaj zog dua.

 

 

Ntxiv nrog rau kev sib xyaw ua ke pub dawb ntawm cov txheej txheem vuam, kuj tseem muaj ntau yam sib txawv ntawm cov vuam cua sov hauv qhov fin. Cov txheej txheem siv feem ntau suav nrog peb cov hauv qab no:

Ib qho yog hu ua lub cev. Cov txheej txheem txheej txheem ntawm hom fin no yog siv cov hlau sawb (tooj liab lossis txhuas) txhawm rau quav rov qab thiab tawm mus tsis tu ncua los ntawm cov khoom siv tau teeb tsa. Nws tuaj yeem folded ntev heev thiab txiav raws li qhov yuav tsum tau ua los ua ib qho qauv zoo li Lub Phab Ntsa Loj. Qhov tshwj xeeb ntawm cov khoom siv hauv nruab nrog cev yog tias tom qab vuam ntawm lub phaj hauv qab, tag nrho cov dab dej kub yog tag nrho, leaning tawm tsam ib leeg, qhov hnyav kuj yog lub teeb, thiab nws muaj lub zog ntawm cov qauv. Yog li ntawd, nyob rau hauv daim ntawv thov, nws yog feem ntau siv nyob rau hauv daim ntawv thov nrog rau qhov hnyav yuav tsum tau thiab nquag hloov kev sib cuag. (Piv txwv li, feem ntau ntsaws rau hauv thiab tawm) ntawm lub dab dej kub, piv txwv li, vertically ntsaws rau hauv tus qauv chassis.

 

Lwm qhov yog hu ua ib daim ntawv folding. Nyob rau hauv cov khoom no, txhua daim ntawv hniav yog punched tawm nyias nyob rau hauv tus txheej txheem, thiab ces lub hauv qab nto yog folded rau hauv lub kaum sab xis los tsim ib tug "L". Nws tseem tuaj yeem raug tso tawm. Raws li cov kev cai sib txawv, Nws tuaj yeem kaw tag nrho lossis ib nrab kaw. Cov txheej txheem no tshwj xeeb tshaj yog tsim rau cov khoom uas muaj ntau yam, cov khoom me me, kev tsim khoom sai, thiab cov nqi pib qis.

 

Hom thib peb yog hu ua buckle sheet. Txoj kev tsim khoom no yog xuas nrig tawm ntawm nws thaum stamping. Tom qab stamping, ib tug buckle yuav muab ntxiv cia li. Tom qab stamping tiav, kev sib xyaw ua ke ntawm cov dab dej kub yuav raug tsim. Qhov nruab nrab yog me ntsis zoo li rub nws zoo li lub zipper los ua kom tiav kev sib xyaw ua ke, yog li nws yog tsim los ntawm cov nplai loj, qhov vuam efficiency siab heev, thiab tus nqi kuj tsawg. Txawm li cas los xij, vim tias nws yuav tsum tau ua pwm, tus nqi pib ntawm kev sim ntau lawm yog qhov siab, thiab lub voj voog ntev.
