Txhuas vs tooj liab: uas zoo dua rau cov cua sov sov?

Ua ntej kev hloov kho lub dab dej kub rau peb cov neeg siv khoom hauv ZP tshav kub lub dab dej, yog thawj kauj ruam yog los txiav txim siab cov khoom raws li cov ntawv thov cov khoom lag luam / phiaj xwm. Aluminium thiab tooj liab yog ob qho tib si niaj zaus cov khoom cua sov, tab sis lawv muaj cov yam ntxwv sib txawv, yog li daim ntawv thov cov xwm txheej yuav txawv.

 

Ua ntej, qhov zoo ntawm txhuas yuav suav nrog lub teeb yuag thiab tus nqi qis. Aluminium yog tsis tshua ntom dua tooj liab, yog li nws sib dua rau tib lub ntim, uas yog ib qho tseem ceeb rau cov khoom siv uas yuav tsum tau txo qhov hnyav. Ib qho ntxiv, txhuas yog feem ntau tsis tshua kim dua tooj liab, uas ua rau nws muaj nqi ntau dua rau huab hwm coj ntau lawm. Raws li cov txheej txheem, txhuas yuav yooj yim dua rau cov khoom siv tsis sib xws thiab ua kom haum rau cov txheej txheem thaum tshav kub nyuaj. Nyob rau hauv cov nqe lus ntawm corrosion tsis kam, txhuas nthuav dav ib txheej oxide ntawm nws sab, uas tej zaum yuav muaj qee qhov kev tiv thaiv, txawm tias yuav tsum muaj kev tiv thaiv nws.

 

Tom qab ntawd cia peb tham txog qhov tsis zoo ntawm txhuas. Nyob rau hauv cov nqe lus ntawm thermal conductivity, txawm hais tias txhuas muaj qhov zoo coefficient ntawm thermal conductivity tej zaum yog li cov tawv nqaij ua tsis tau zoo li tooj liab. Nyob rau hauv cov nqe lus ntawm lub zog, txhuas yuav softer thiab yooj yim rau deform, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj zog rau kev ruaj khov. Nyob rau hauv cov nqe lus ntawm kev nyuaj vuam nyuaj, Txhuas tej zaum yuav tau muaj txuj ci tshwj xeeb, xws li Arcon arc vuam, uas yuav nce cov nqi ntau lawm.

 

 

Tom ntej no yog qhov zoo ntawm tooj liab. Tooj liab muaj qhov siab dua cov kev ua haujlwm hnyav dua li txhuas, uas txhais tau ntau dua cov cua sov dissipation rau cov khoom siv hluav taws kub high. Tooj liab muaj zog dua, tiv thaiv ntau dua rau cov kub, tsawg dua qub rau deformation, thiab tej zaum yuav muaj sijhawm ntev. Nyob rau hauv cov nqe lus ntawm solderability, tooj liab, txawm hais tias nws siab yaj yaj, ua rau muaj zog txuas ntxiv tom qab siv rau cov kev pab kom muaj kev cia siab.

 

Qhov tsis zoo ntawm tus tooj liab yog thawj tus nqi siab, cov khoom siv raw yog kim thiab kev ua tiav yog ntau vim tias tooj liab hnyav dua thiab nyuaj rau kev ua haujlwm. Nyob rau hauv cov nqe lus ntawm qhov hnyav, tooj liab yog denser thiab lub dab dej sov yuav hnyav dua, ua rau tsis muaj peev xwm rau cov ntawv thov hnyav. Corrosion tsis kam, tooj yog yooj yim rau oxidize, txawm hais tias nws tsis cuam tshuam rau lub zog tooj liab, tab sis nws yuav cuam tshuam rau lub zog ntawm thermal, tab sis nws yuav cuam tshuam rau lub zog, ntev nyob rau hauv ib puag ncig huab cua yuav muaj ntau yam teeb meem.

 

Tom qab ntawv thov cov xwm txheej ntawm cov neeg siv khoom cov khoom yuav tsum tau txiav txim siab. Raws li kev tsim kho customized ntawm kev lag luam tshav kub kub, peb yuav tsum xav txog cov kev xav tau ntawm cov chaw muaj kev lag luam sib txawv. Piv txwv li, cov khoom siv hluav taws xob siab yuav xav tau cov thermal hermal conductivity ntawm tooj liab, thaum lub sij hawm them nqi lossis lub plhaub me me yuav haum rau txhuas. Tsis tas li, nyob rau hauv cov nqe lus ntawm cov txheej txheem ntau lawm, txhuas extrusion yog haum rau huab hwm coj ntau lawm, thaum tooj liab yuav siv ntau rau cov kev daws teeb meem thermal uas yuav tsum tau ua haujlwm ntau dua.

 

Tam sim no peb yuav xav txog kev siv cov khoom siv sib xyaw ua ke ntawm ob cov ntaub ntawv thiab cov tawv nqaij ceev thiab txhuas kom zoo dua qub thiab cov nqi qis kub dissipation ntawm txhuas. Tab sis qhov no yuav muaj qhov teeb meem ntawm interface thermal kuj thiab yuav xav tau kev sib dhos zoo lossis koom nrog cov tswv yim.

 

Peb kuj yuav tsum xav txog qhov rov ua dua tshiab ntawm tooj liab lossis ib puag ncig? Nws yuav yog tias txhuas yog yooj yim dua rov qab, tab sis cov neeg muas zaub yuav txhawj xeeb txog kev ua tau zoo thiab raug nqi. Tsis tas li ntawd, muaj peev xwm ua kom sov, tooj liab muaj lub zog cua sov siab dua li txhuas, tab sis feem ntau cua sov kev txhawj xeeb nrog cov thermal conductivity thiab thermal kuj. Cia peb saib ntawm lub thermal conductivity muaj nuj nqis ntawm ob cov ntaub ntawv, txhuas yog li 237 w / mk, tooj liab yog kwv yees li 401 w / mk. Ceev, txhuas yog hais txog 2700 kg / mg, tooj liab yog hais txog 8900 kg / mg.

 

 

 

 

1. Lub teeb yuag
- Tsawg ntom ntom (kwv yees li 2700 kg / mg) thiab 1/3 qhov hnyav ntawm tooj liab, ua kom haum rau cov ntawv thov hnyav (piv txwv li cov khoom siv hluav taws xob, cov cuab yeej siv hluav taws xob).

2. Tus nqi qis
- Cov khoom siv raw yog qhov qis dua li tooj liab, thiab kev tsim cov nqi kuj qis dua (piv txwv li, lub extrusion moulding txheej yog paub tab), ua rau nws haum rau huab hwm coj ntau lawm.

3. Kev ua tau zoo heev
- Yooj yim dua rau hauv cov qauv ua tiav, ua rau cov khoom siv nrawm nrawm, lub teeb ci, qhov chaw kub ua kom cua sov.

4. Corrosion Kuj
- Lub ntuj oxide txheej (al₂o₃) nyob rau saum npoo tiv thaiv tawm tsam xeb, thiab lub durability tseem zoo dua tom qab anodizing.

 

 

 

1. Qis dua thermal conductivity
- Thermal conductivity ntawm 237 W / MK, tsuas yog 60% ntawm tooj liab, thermal efficiency yog txwv, tsis haum rau huab siab zog cov xwm txheej.

2. Lub zog ua haujlwm muaj zog
- Yooj yim softened thiab deformed ntawm kev kub siab, kev siv ntev yuav ua rau poob rau hauv kev poob qis hauv cov qauv kev ruaj ntseg.

3. Ntau dua vuam nyuaj
- Argon arc vuam thiab lwm cov txheej txheem tshwj xeeb, nce kev tsim khoom tsim khoom.

 

 

 

1. Zoo heev thermal conductivity
- Thermal conductivity ntawm 401 W / MK, kev nqus kub thiab kev hloov pauv kub sai dua, xws li cov ntaub ntawv hluav taws xob ntau dua (xws li cov ntaub ntawv hluav taws xob siab (xws li cov ntaub ntawv, high-kawg graphics).

2. Muaj Zog Txhua Yam
- Cov kev kub siab tsis kam thiab tsis yooj yim rau deform, kev ruaj khov ntev tau zoo dua txhuas.

3. Kev ntseeg siab vuam
- Muaj zog welding pob qij txha, haum rau muaj kev muaj xwm txheej muaj xwm txheej nrog kev ntseeg siab.

 

 

 

1. Tus nqi siab
- Tus nqi ntawm raw cov ntaub ntawv yog 3-5 lub sij hawm siab dua li ntawm txhuas, thiab kev ua hluav taws xob ntau (xws li, txiav thiab stamping yog qhov nyuaj).

2. Siab hnyav
- Cov ceev yog siab npaum li 8900 kg / mg, uas nce qhov hnyav tag nrho ntawm cov khoom siv.

3. Txiaj Ntsig Oxidation Kuj
- Cov saum npoo oxidizes yooj yim (mob yog tsim) thiab xav tau kev kho mob xws li noickel plating los tiv thaiv kev puas tsuaj ntawm cov tsos mob, thiab electrochemical corrosion yuav tshwm sim hauv cov chaw noo noo.

 

 

 

Cov xwm txheej zoo rau Aluminium: Nqi-rhiab, yuav tsum muaj kev cuam tshuam rau nruab nrab, piv txwv, LED teeb pom kev zoo, cov neeg siv khoom hluav taws xob).

Cov xwm txheej zoo nkauj rau tooj liab: huab cua sov dissipation xav tau, siab ntseeg cov cuab yeej siv, hluav taws xob hluav taws xob).
Hybrid daws: Tooj lub luj taws (nrawm kub nqus dej), ntsuas kub ntxhov thiab siv nyiaj ntau dua, tab sis yuav tsum tau siv zog ua haujlwm (piv txwv li reflow soldering lossis los ntawm cov txheej txheem nti).

Los ntawm kev xav txog thermal conductivity, raug nqi, qhov hnyav thiab cov ntaub ntawv tsim nyog lossis cov kev daws teeb meem uas tsim nyog tshaj plaws, yuav raug xaiv los ntawm cov kev thov tshwj xeeb.

 

Tam sim no cov khoom koj xaiv, ZP lub dab dej sov yuav xaiv cov khoom siv hluav taws xob rau koj cov khoom lossis phiaj xwm kev thov kom paub tseeb tias cov cua sov hloov cov khoom lag luam.
