Nrog cov qauv ntawm kev ua tau zoo thiab miniaturization ntawm cov khoom siv hluav taws xob, cov khoom siv thermal, yog qhov tseem ceeb los xyuas kom cov haujlwm ruaj khov ntawm cov khoom siv.
Cov kab xev thermal yog cov ntaub ntawv nyias nyias yog cov khoom siv thermal heral conductivity thiab tsev ua haujlwm, feem ntau yog nyob rau hauv daim ntawv ntawm siab (PSA rhiab). Nws cov haujlwm tseem ceeb yog tsim kom muaj kev kub ntxhov kub ntxhov ntawm cov hluav taws xob thiab cua sov txhim kho kev siv hluav taws xob, thaum muab cov roj cua sov txhim kho.
Vim li cas peb thiaj xav tau daim kab xev thermal?
Ua tau zoo heev thermal conduction
Sau rau lub tshuab tsom iav me me ntawm cov khoom siv thiab cua sov (huab cua sov (huab cua yog tus neeg xyuas kev ua haujlwm tsis zoo), txo qis kev cuam tshuam ntawm kev cuam tshuam cua sov.
Lub thermal conductivity coefficient (k tus nqi) li ntawm 0.5 mus rau 6.0 w / mk, thiab siab}} {} Kev ua haujlwm zoo tuaj yeem ncav ntau dua 10 w / mk.
Kev sib txuas ua ke thiab kub dissipation
Ua tiav cov tshuab txhim kho thiab cua sov hloov tib lub sijhawm, piv txwv txoj kev sib dhos, thiab txo cov nqi sib dhos.
Zam kev thov tsis sib xws, ziab lossis roj pom ntawm silicone roj, thiab txhim kho ntev- sij hawm kev ntseeg tau.
Kev Rwb Hluav Taws Xob
Most Thermal Tapes have high dielectric strength (>3 KV / hli), uas tiv thaiv cov kab luv luv thiab ua kom pom tseeb circuit kev nyab xeeb.
Ultra - thinness thiab kev yoog tau
Lub thickness kuj yuav muaj tsawg li 0.05mm, uas yog haum rau kev cog qoob loo tsim nrog txwv chaw (ntsiav tshuaj, thiab ultra- Cov ntawv sau nyias).
Nws tuaj yeem txuas nrog nkhaus lossis cov chaw tsis tu ncua.
Hnyav - dawb, qis tsis tau
Ua tau raws li cov pa phem - kev ua tiav dawb yuav tsum muaj ntawm cov khoom siv hluav taws xob.
Thermal daim kab xev cov chaw thov tseem ceeb
Cov Neeg Siv Khoom Electronics
Txawb xov tooj / ntsiav tshuaj: CPU, roj teeb, teeb, backplicpan tshav kub dissipation
Phau Ntawv: SSD, GPU, VRM module tsevneeg ua kom sov
LED teeb pom kev zoo
Thaum tshav kub kub hloov ntawm LED Chips rau txhuas substrates kom txuas lub teeb deck
Automotive Electronics
Automotive Qib Yuav Tsum Tau Ua: ECU, taws teeb, BMS module kub dissipation (kub tsis kam, kev co tawm tsam)
Cov Khoom Siv Txuas Lus
5G lub chaw nres tsheb autau, kho qhov muag tsis zoo, router nti kub dissipation
Muaj Cov Khoom Siv Hluav Taws Xob
Igbt, Mosfet ntaus ntawv, thiab lub dab dej kub siab
Cov Cai Golden rau xaiv cov kab xev thermal
Ntshiab Thermal yuav tsum tau
Xam cov hwj huam noj (w) thiab pub ntsuas kub (ΔT) ntawm cov khoom siv, thiab thim tus nqi k lossis thermal kuj tus nqi.
Hluav Taws Xob Hluav Taws Xob Kev Ua Haujlwm
Is it necessary to isolate high voltage? Confirm the breakdown voltage value (such as >3KV).
Chaw thiab Thickness Txwv
Ultra - nyias (<0.1mm) select graphene or phase change tape.
Ib puag ncig kev yoog
Silicone is preferred for high-temperature environments (>150 degree); Siab shear lub zog daim kab xev yog qhov yuav tsum tau rau kev co scenes.
Tsevneeg Cov Cwj Pwm Qub
Cov ntaub ntawv hluav taws xob tsis tshua muaj zog (xws li pp plastics) yuav tsum tau lo kua nplaum nrog lub ntsej muag muaj teeb meem siab.
Thermal Daim Kab XevTau dhau los ua cov khoom txheem rau high - qhov ceev hluav taws xob tsim nrog nws tus nqi hluav taws xob tshwj xeeb ntawm kev tswj hwm cua sov + qauv txheej txheem kev txhim kho.
