Thermal Pads: Cov "Hidden Heroes" ntawm Thaum tshav kub kub Dissipation
Xav txog tias koj lub xov tooj tau kub heev tom qab peb teev ntawm kev txuas mus ntxiv uas koj tuaj yeem kib qe rau nws; koj lub khoos phis tawj humming nrov, nws kub nce mus rau "liab cheeb tsam"-tom qab cov xwm txheej no yog qhov ntsiag to ntawm cov thermal pads. Raws li "sib koom ua ke cua sov" rau cov khoom siv hluav taws xob, lub luag haujlwm tseem ceeb ntawm thermal pads yog los sau cov qhov khoob me me ntawm cov nti thiab cov heatsink, ua raws li "choj" kom ua kom sov sai sai. Nws txoj hauv paus ntsiab lus yog yooj yim: siv cov ntaub ntawv thermally conductive xws li silicone thiab ceramic, nws "flattens" qhov chaw siab - kub cov ntsiab lus mus rau tag nrho cov tshav kub dissipation nto, tiv thaiv tshav kub buildup thiab degradation. Piv txwv li, rau txhua txhua 10℃txo nyob rau hauv CPU kub ntawm ib tug gaming laptop, kev ua tau zoo poob yuav raug txo los ntawm 20%, thiab ib tug haum thermal ncoo yog qhov tseem ceeb rau ua kom tiav lub hom phiaj no.
Daim Ntawv Qhia Kev Xaiv: Thickness, Hardness, thiab Thermal Conductivity-Txhua yam yog qhov tseem ceeb
Xaiv ib lub thermal ncoo zoo li xaiv khau -qhov tseem ceeb tshaj plaws yog qhov haum zoo! Ua ntej, xav txog cov hauv qab no:
Thickness: Qhov sib txawv ntawm cov nti thiab cov heatsink yog feem ntau ntawm 0.5-5mm. Ib lub ncoo uas tuab dhau yuav tsis haum zoo, thaum lub ncoo uas nyias dhau yuav tsis ua rau qhov sib txawv. Nws raug nquahu kom ntsuas qhov sib txawv tiag tiag nrog calipers ua ntej xaiv.
Thib ob, xav txog cov hauv qab no:
Hardness: Nias lub ncoo nrog koj tus ntiv tes. Yog tias nws yooj yim tawm ntawm tus ntiv tes, qhov hardness tsawg (tsim rau qhov tsis sib xws); yog tias nws nyuaj rau nias, lub hardness yog siab (tsim rau precision installation).
Thaum kawg, xav txog cov hauv qab no:
Thermal conductivity: Tus nqi siab dua txhais tau tias kev ua kom sov sai dua, tab sis tsis txhob ua qhov muag tsis pom qhov muaj txiaj ntsig zoo -3-5W / m·K cov ntaub qhwv muaj txaus rau cov khoos phis tawj CPUs zoo tib yam, thaum daim npav ua haujlwm siab yuav xav tau 8-12W / m·K qauv. Nco ntsoov: Txawm tias muaj thermal conductivity, nws tsis muaj txiaj ntsig yog tias lub installation tsis nruj!
Cov Lus Qhia Txog Kev Siv: Cov ntsiab lus no muab ob npaug rau koj qhov Kev Tiv Thaiv Thaum Tshav Kub Kub Thaum txhim kho cov thermal pads, 90% ntawm cov neeg saib xyuas cov "cov kauj ruam zais" no: Ua ntej, ntxuav cov nti thiab cov cua sov kom zoo nrog cov cawv cawv. Plua plav thiab roj yuav tsim ib tug "kub rwb thaiv tsev txheej," halving lub tshav kub conduction efficiency. Thib ob, txiav cov pads 1-2mm loj dua qhov loj me kom tsis txhob nqa cov npoo thiab ua rau cov cua sov. Thib peb, nias ntawm qhov chaw sab nraud thaum lub sijhawm teeb tsa kom tshem tawm cov npuas npuas-txawm tias lub npuas me me tuaj yeem txo cov thermal conductivity hauv zos los ntawm 50%! Yog tias koj tab tom hloov cov ntaub qhwv rau cov khoom siv ntau zaus xws li daim npav duab thiab cov khoom siv fais fab, nws raug nquahu kom kuaj xyuas lawv txhua 2-3 xyoos. Cov laus thiab cov ntaub qhwv tawv tawv yuav plam lawv cov elasticity, txo lawv cov nyhuv tshav kub. Master cov tswv yim no, thiab koj cov cuab yeej yuav nyob twj ywm "txias"!
