Thermally qhuab qhia Silicone cov ntaub qhwv yog cov tshuaj polymer ua los ntawm cov roj hmab silicone thiab tshwj xeeb ua rau cov filters. Ntxiv rau kev ua mos, lawv muaj cua sov zoo, yooj, thiab rwb thaiv tsev zoo.
Cov laj thawj tseem ceeb thiab siv los ntawm kev coj ua silicone pads
Thermally ua raws silicone padsFeem ntau siv rau kev sau sib txawv, hloov cua sov, nqus qhov poob siab, thiab lub ncoo.
Kaw cov khoob: Cheebtsam hluav taws xob (xws li daim tawv nyias thiab mosfets) thiab cov tsev sov lossis cov tsev uas nquag muaj cov cua txias ntawm lawv. Kev hloov pauv kub tau zoo heev los ntawm huab cua, uas yog ib tus neeg coj ua cua sov. Thermally ua raws silicone pads 'muag kev ntxhib los mos ua rau lawv muaj peev xwm sau rau cov chaw tsis sib xws thiab tso tawm huab cua.
Hloov Thaum Tshav Kub Kub: los ntawm kev sib sau ua tau zoo kub ntws channel ntws tau sau, Thermally txav qis thiab tsis txaus siab txav tshav kub los ntawm tshav kub kub los ntawm tshav kub.
Poob siab nqus: nws elastomeric zoo txaus tiv thaiv cov hluav taws xob sib xyaw los ntawm kev nqus thiab kev co kom poob thiab kev co.
Kev Rwb Hluav Taws Xob: Kev Nyab Xeeb Siv yog ua kom zoo los ntawm Silicone Cov Khoom Siv Hluav Taws Xob Cov Hluav Taws Xob.
Cov chaw thov tseem ceeb:
LED teeb pom kev zoo: tshav kub conduction ntawm LED teeb LED teeb thiab txhuas cov substrates thiab cov dab dej kub ua dab dej.
Cov Khoom Siv Hluav Taws Xob: Hauv Kev Hloov Power Khoom Siv thiab Inverters, cov no muab cov kev rwb thaiv tsev sov ntawm cov vaj tse thiab fais fab hluav taws xob.
Cov roj teeb pob thermal tswj (BMS), lub cev muaj zog controllers, thiab nyob rau {{} board chargers (OBCS) yog feem ntawm lub zog hluav taws xob tshiab.
Ntws txias hauv cov khoos phis tawm, cov npav duab, cov routers, thiab cellones yog ib qho piv txwv ntawm cov neeg siv khoom hluav taws xob.
Cov Khoom Sib Txuas Lus: Txias tshuab rau cov servers, kho qhov muag, thiab 5g puag ncig.
Yuav ua li cas thiaj li yuav zoo tshaj thermal silicone pav tau xaiv?
Cov hauv qab no tseem ceeb yuav tsum tau coj mus rau hauv tus account thaum xaiv ib lub thermal silicone ncoo:
Conductivity ntawm tshav kub
W / m · k yog chav tsev. Ntau dua thermal conductivity yog qhia los ntawm tus nqi siab dua. 1.0} W / m · k yog ntau tshaj 10.0 w / m · k yog qhov tseem ceeb.
Xaiv raws li kev siv fais fab ntawm cov cua sov thiab qhov yuav tsum tau kub ua cua sov. Tus nqi siab dua tsis tas yuav zoo dua; Tus nqi - ua tau zoo yuav tsum tau txiav txim siab. Rau cov ntawv thov dav dav, 1.5- 3.0 w / m · k txaus, thaum 6.0 w / min k thiab sab saud yog pom zoo rau cov xwm txheej siab-lub zog. Qhov tuab
Nov yog ib qho kev xaiv tseem ceeb tshaj plaws. Lub thickness yuav tsum muaj ntau dua los yog sib npaug ntawm cov rooj sib txoos thiab txig sau qhov chaw tom qab compression.
Ntsuas cov kis xwm txheej tiag tiag ntawm cov cua sov thiab lub tshuab cua sov thiab xaiv lub gasket uas yog 10% thicker uas tuab dua ntawm nws cov kev sib tw los sau cov kis.
Kev nyuaj
Qhov no feem ntau qhia nyob rau hauv ntug dej C hardness. Qhov qis dua tus nqi, cov softer cov khoom thiab qhov yooj yim dua nws yog kom zaws kom haum rau saum npoo.
Rau cov khoom nrog cov chaw tsis ncaj lossis cov uas muaj kev cuam tshuam rau kev ua kom muaj compression (xws li chips), xws li ntug dej C 20-40) yuav tsum tau xaiv. Ib lub gasner nyuaj (xws li ntug dej C 50-80) muaj zog ntau tab sis yuav tsum tau teeb tsa siab dua.
TIM DAWB VALPETage
Qhov no qhia tau lub zog ntawm lub peev xwm rwb thaiv tsev, ntsuas hauv kv / hli. Qhov ntsuas no yog qhov tseem ceeb rau cov ntawv thov uas xav tau siab- voltage rulation (xws li lub zog modules). Ntim Resistivity (ntim resistivity)
Ntxiv nrog rau kev ntsuas rwb thaiv tsev rwb thaiv tsev ua haujlwm, chav tsev yog ω ω ω; ntau dua qhov tseem ceeb qhia tau tias rwb thaiv tsev zoo dua.
Kev ntsuas kev nyab xeeb thiab nquag tuav cov lus qhia txog kev siv thermal silicone pads
Ua rau lub sab huv: kom tiv thaiv kev cuam tshuam thermal conductivity, nco ntsoov cov chaw cua sov thiab lub tshav kub yog ziab, thiab roj dawb ua ntej thov.
Txheeb pom tseeb ntawm kev ncab ntau dhau: Thaum tuav thiab kev teeb tsa, siv ceev faj, ntau dhau kev ncab yuav ua rau kua muag lossis deformation.
Compression Piv: Thermal silicone cov ntaub qhwv uas tau compressed ntawm 10% thiab 30% feem ntau muaj qhov zoo tshaj thermal conductivity. Txhawm rau tiv thaiv kev puas tsuaj rau ib feem lossis hauv ncoo nws tus kheej, tsis txhob siv ntau dhau kev txhim kho siab.
Myth: Nws zoo dua yog muaj ntau thermal conductivity. Gaskets nrog nruab nrab rau tsawg tshav kub conductivity yog haum rau ntau cov ntawv thov. Ntau cov thermal conductivity gaskts yog nquag stiffer thiab xav tau ntau lub siab nias; Yog li, ua raws lawv lub siab yuav cia li tsav tsheb ntau.
HYTH: Zoo dua, Thicker tshav kub dissipation yog cuam tshuam los ntawm ntau dhau gaskets vim tias lawv nce thermal tsis kam. Xaiv ib thickness uas sib haum rau qhov sib txawv. Silicone packs uas ua kom muaj cua sov yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob cov tshuab tswj hluav taws xob thermal. Kev xaiv thiab siv txoj cai thermally coj silicone ncoo tuaj yeem nce ntxiv cov khoom ruaj khov, kev vam meej, thiab lub neej.
