Tshawb nrhiav cov khoom siv hluav taws xob: Unsung Heroes ntawm Thaum tshav kub kub dissipation hauv Electronic Devices

Tsev neeg, thev naus laus zis tau txhim kho sai heev hnub no, thiab cov khoom siv hluav taws xob tau ntev dhau los ua qhov tseem ceeb hauv peb lub neej. Peb tau sawv los ntawm peb lub xov tooj tswb kom pib hnub; computers pab peb ua hauj lwm zoo; thiab hauv peb lub sijhawm dawb, peb siv cov ntsiav tshuaj los saib cov yeeb yam thiab ua si. Tab sis cov cuab yeej no zoo li overheat tom qab siv ntev. Piv txwv li, thaum ua si nrov mobile games, lub vijtsam game pib lag thiab cov kev tswj tsis ua haujlwm thaum lub xov tooj kub; Yog tias lub khoos phis tawj ua haujlwm xav tau software rau lub sijhawm ntev, rooj plaub tau kub heev, kiv cua kiv nrov, thiab nws tuaj yeem tsoo. Ntxiv mus, overheating tsis tsuas yog cuam tshuam rau cov neeg siv kev paub tab sis kuj tuaj yeem ua rau lub cuab yeej puas thiab ua rau nws lub neej luv. Vim li cas qhov no tshwm sim? Vim tias thaum cov khoom siv khiav, cov khoom siv hluav taws xob sab hauv tsim hluav taws xob ntau thaum ua cov ntaub ntawv. Yog tias qhov cua sov no tsis ploj mus rau lub sijhawm, nws sib sau ua ke, nce qhov kub thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom, ua haujlwm qeeb, thiab ua rau muaj kev ua haujlwm tsis zoo. Qhov no yog qhov uas cov ntaub ntawv kub dissipation ua ib qho tseem ceeb heev, thiab cov thermal pads yog ib qho cuab yeej muaj zog hauv qhov no. I. Cov Txheej Txheem Tshaj Tawm Cov thermally conductive silicone ncoo yog tsim los ntawm substrate thiab thermally conductive fillers, txhua tus ua lub luag haujlwm tseem ceeb. (I) Substrate - Cov Khoom Zoo Tshaj Plaws ntawm Silicone Roj Hmab Silicone roj hmab, raws li cov substrate, yog cov khoom siv elastomer uas muaj cov silicon{10}} cov pa roj hmab, thiab nws cov khoom yog amazing tiag tiag! Nws muaj qhov tshwj xeeb muaj zog tiv thaiv rau qhov kub thiab txias, tseem ruaj khov nyob rau hauv thaj tsam ntawm -50℃txog 200℃. Txawm hais tias nyob rau hauv qhov txias Arctic los yog cov suab puam scorching, nws ntseeg tau muab cua sov dissipation rau cov khoom siv. Txawm hais tias cov khoom siv sab nraum zoov ntsib qhov kub qis hauv lub caij ntuj no lossis kub kub hauv lub caij ntuj sov, silicone roj hmab ua haujlwm ib txwm. Nyob rau tib lub sijhawm, nws cov khoom siv rwb thaiv tsev zoo heev, ua haujlwm zoo li "insulating tiv thaiv suit" rau cov khoom siv hluav taws xob, tiv thaiv kev xau tam sim no, ua kom ruaj khov tam sim no, thiab kev ua haujlwm ruaj ntseg. Tsis tas li ntawd, cov roj hmab silicone muaj cov tshuaj lom neeg ruaj khov, tsis yooj yim rau lwm cov tshuaj, thiab tseem nyob ruaj khov txawm tias nyob rau hauv ib puag ncig tshuaj lom neeg, ua kom lub sijhawm ntev - ua haujlwm zoo ntawm thermally conductive silicone ncoo. Nws zoo heev yooj yooj yim tso cai rau lub thermally conductive silicone ncoo kom nruj raws li qhov chaw tsis xwm yeem, txo kev tiv thaiv thermal, zoo kawg nkaus sau qhov khoob ntawm cov khoom thiab cov dab dej kub, thiab txhim kho kev ua haujlwm kub. (II) Thermally Conductive Fillers - Qhov tseem ceeb rau kev ua tau zoo ntawm Silicone roj hmab substrate ib leeg tsis txaus; thermally conductive fillers yuav tsum tau ntxiv los txhim kho thermal conductivity. Cov fillers muaj xws li alumina (Al₂O₃), boron nitride (BN), thiab magnesium oxide (MgO), tag nrho cov uas muaj thermal conductivity zoo heev. Piv txwv li, Alumina yog yooj yim, raug nqi - zoo, thiab ua pov thawj zoo tshuaj stability thiab hnav tsis kam. Thaum sib npaug sib faib nyob rau hauv silicone roj hmab matrix, nws tsim ib tug thermally conductive network, accelerating tshav kub hloov. Boron nitride muaj ntau dua thermal conductivity thiab rwb thaiv tsev zoo, kom ntseeg tau tias kev hloov hluav taws xob tsis cuam tshuam rau cov khoom siv hluav taws xob. Txawv thermally conductive fillers muab qhov tshwj xeeb zoo hauv kev ua tau zoo, thiab lawv cov kev xaiv thiab kev faib ua feem cuam tshuam rau kev ua haujlwm ntawm thermally conductive silicone ncoo. Kev xaiv tsis raug lossis kev faib ua feem tuaj yeem cuam tshuam cov thermal conductivity. Yog li ntawd, manufacturers yuav tsum ua tib zoo xaiv thiab rationally kho cov proportions raws li daim ntawv thov scenario thiab yuav tsum tau. Piv txwv li, siab -kev ua tau zoo ntawm lub computer processor txias yuav siv boron nitride, nrog rau kev tswj xyuas meej ntawm nws qhov piv rau silicone roj hmab. II. Ua kom tiav Kev Ntsuam Xyuas Cov Txheej Txheem Txheej Txheem Kev tsim cov txheej txheem ntawm thermal conductive silicone pads yog qhov nyuaj heev, suav nrog ntau cov kauj ruam tseem ceeb.
