Nyob hauv lub ntiaj teb ntawm electronics thiab thermal kev tswj hwm, nkag siab cov khoom ntawm cov ntaub ntawv ntawm tooj liab thiab txhuas yog qhov tseem ceeb heev. Cov hlau no feem ntau siv nyob rau hauv cov khoom siv hluav taws xob, uas pab txias cov khoom siv hluav taws xob los ntawm kev hloov pauv ntawm cov khoom sib dhos. Tab sis koj yuav xaiv li cas ntawm tooj liab thiab txhuas li cas rau ib qho cua sov? Kab lus no yuav tshawb txog qhov sib txawv ntawm thermal conductivity, kev ua tau zoo, thiab kev siv ntawm ob qho ob qho no.

 

 

Cov hauv paus ntawm thermal conductivity

Thermal conductivity yog cov khoom siv muaj peev xwm ua kom muaj cua sov. Thaum nws los txog rau cua sov dissipation hauv cov khoom siv hluav taws xob, cov ntaub ntawv nrog cov thermal conductivity yog nyiam. Qhov no yog vim tias lawv tuaj yeem hloov chaw hloov cua sov sai li ntawm qhov chaw, pab kom tswj kev ua haujlwm zoo tshaj plaws.

Tooj liab: tus neeg ua si kub

Tooj liab zoo -}}}} paub rau nws cov cua sov zoo heev. Nws muaj qhov thermal conductivity ntawm txog 400 watts ib meter '- kelvin (w / min k), ua rau nws yog ib qho ntawm cov hlau zoo tshaj plaws rau cov kev hloov pauv kub. Qhov kev ua haujlwm siab no txhais tau hais tias tooj liab tuaj yeem cuam tshuam cov cua sov, ua rau nws xaiv nrov rau lub siab- kev ua haujlwm wicksinks.

Aluminium: Hnav thiab txuag

Aluminium, ntawm qhov tod tes, muaj qis dua thermal conductivity piv rau tooj liab, ntawm kwv yees li ntawm 235 w / min k. Dua li ntawm qhov no, txhuas tseem dav siv nyob rau hauv heatsinks. Vim li cas? Vim tias txhuas yog ntais thiab tsawg dua tooj liab, ua rau nws tus nqi {-}}}}}} kev xaiv rau ntau yam kev siv.

 

 

 

Tooj Tooj Vs. Aluminium: Cov Lus Qhia Tshaj Tawm

Tam sim no peb nkag siab cov khoom tseem ceeb ntawm tooj liab thiab txhuas, cia cov delve ntxaum rau cov ntaub ntawv no piv, raug nqi, thiab kev siv.

Kev ua tau zoo hauv tshav kub dissipation

Thaum nws los txog rau kev ua tau dawb huv hauv tshav kub dissipation, tooj liab yog tus yeej vim nws siab dua thermal conductivity. Qhov no ua rau nws zoo tagnrho rau cov xwm txheej uas ntau tshaj qhov hloov cua sov yog qhov tsim nyog, xws li nyob rau hauv high electronics lossis overclocked computer processors.

Txawm li cas los xij, txhuas tsis nyob tom qab. Nws cov thermal conductivity tseem muaj ntau txaus rau feem ntau cov neeg siv khoom lag luam thiab cov ntawv thov txhua hnub. Tsis tas li ntawd, txhuas heatsinks tuaj yeem tsim tau nrog thaj chaw loj dua kom them nyiaj rau nws cov thermal conductivity.

Tus nqi thiab cov kev txiav txim siab hnyav

Ib qho ntawm qhov tseem ceeb ntawm txhuas ntau dua tooj liab yog nws tus nqi. Txhuas yog feem ntau pheej yig los tsim khoom thiab cov txheej txheem, uas tuaj yeem ua rau qis dua cov nqi tag nrho rau txhuas watchsinks. Tus nqi no - ua hauj lwm zoo ua rau txhuas ib qho kev xaiv muaj zog rau huab hwm coj-} tsim hluav taws xob.

Nyob rau hauv cov nqe lus ntawm qhov hnyav, txhuas yog sib dua dua tooj liab. Qhov no tuaj yeem yog qhov tseem ceeb ntawm cov ntawv thov uas qhov hnyav yog qhov kev txhawj xeeb, xws li hauv cov hluav taws xob Portable lossis cov khoom siv hluav taws xob.

Corrosion Kuj

Tooj liab yog nquag mus rau oxidation thiab corrosion, tshwj xeeb tshaj yog nyob rau hauv huab cua noo. Txhawm rau tawm tsam qhov no, tooj liab watchsints feem ntau yog coated lossis plated nrog lwm cov hlau, xws li npib tsib. Aluminium ib txwm ua cov txheej oxide tiv thaiv, ua rau nws tiv taus corrosion yam tsis muaj kev kho mob ntxiv.

 

Cov ntawv thov ntawm tooj liab thiab txhuas heatsinks

Qhov kev xaiv ntawm tooj liab thiab txhuas cov cua sov feem ntau yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov.

High - Kev Ua Tau Zoo

Nyob rau hauv high - Performance} Kev ua yeeb yam, uas kub siab tuaj yeem tseem ceeb rau lawv cov cua sov thermal zoo dua. Lawv tuaj yeem tswj hwm cov cua sov siab ntawm cov processors muaj zog.

Txhua hnub cov neeg siv khoom siv hluav taws xob txhua hnub

Rau feem ntau cov neeg siv khoom hluav taws xob feem ntau, xws li lub laptop, smartphones, thiab cov khoom siv khoom siv hauv tsev, txhuas cov cua sov muaj ntau dua. Lawv qhov sib npaug ntawm tus nqi, qhov hnyav, thiab txaus thermal conderivity ua rau lawv haum rau cov ntawv thov no.

Automotive thiab Aerospace Kev Lag Luam

Nyob rau hauv kev lag luam hauv tsheb thiab aerospace, qhov hnyav yog qhov tseem ceeb tshaj plaws, txhuas feem ntau yog cov khoom siv ntawm kev xaiv. Nws lub teeb yuag yuag yuav pab txhim kho kev txuag roj thiab ua tau zoo hauv tsheb thiab cov dav hlau.

 

 

 

 

Xaus: Xaiv cov khoom raug

Hauv cov ntsiab lus, ob qho tooj liab thiab txhuas muaj lawv cov chaw nyob hauv lub ntiaj teb ntawm watchsinks. Tooj liab zoo li nyob rau hauv cov xwm txheej uas thov kom muaj zog tshaj plaws thermal tab sis los ntawm tus nqi siab dua thiab qhov hnyav. Aluminium muaj ntau tus nqi pheej yig dua thiab lub teeb meem teeb liab thaum tseem ua rau muaj kev tswj hwm txaus rau ntau yam.

 

Thaum xaiv tooj ntawm tooj liab thiab txhuas cov kev xav tau, xav txog cov kev xav tau tshwj xeeb, suav nrog cov kev xav tau kev ua tau zoo, suav nrog cov kev xav tau, thiab kev txiav txim siab hnyav. Los ntawm kev nkag siab cov khoom ntawm txhua cov khoom, koj tuaj yeem xaiv tau kev txiav txim siab kom ntseeg tau tias koj cov khoom siv hluav taws xob tseem nyob txias thiab muaj txiaj ntsig.

 

Nco ntsoov, tus yuam sij rau kev tswj tshav kub ua haujlwm tsis yog nyob hauv cov khoom tab sis kuj hauv cov qauv thiab kev siv ntawm cov cua sov. Txawm hais tias koj xaiv tooj liab lossis txhuas, xyuas kom koj cov cua sov yog tsim los ua kom muaj airflow thiab thaj chaw rau kev ua si zoo tshaj plaws.

 

Los ntawm ua tib zoo xaiv cov khoom siv hluav taws xob kom muaj cov khoom siv thiab kev ua tau zoo ntawm koj cov khoom siv hluav taws xob, ua kom lawv khiav zoo hauv qab kev ua haujlwm.

 

 

ZP rhaub dej kub tau raug tshwj xeeb hauv cov khoom siv hluav taws xob kev cai rau 20 xyoo. Peb tuaj yeem muab cov tshuaj zoo tshaj plaws ntawm cov cua sov so rau koj qhov project thermal hauv cov khoom siv, thev naus laus zis}}} pib thawj kauj ruam ntawm koj qhov phiaj xwm cua sov.
