Puas yog nws zoo dua los siv daim ntawv mica rau lub tshav kub dissipation insulating ntawv ntawm lub triode, los yog nws puas zoo dua los siv silicone ncoo
Oct 24, 2022
Kev teeb tsa lub hwj chim amplifier fais fab raj (cov khoom siv hluav taws xob) txhua tus yuav tsum tau nruab cov ntaub ntawv insulating kom cais lawv ntawm cov dab dej kub (tshwj tsis yog cov qauv hluav taws xob tshwj xeeb). Txawm hais tias muaj txhua yam ntawm thermally conductive insulating nplooj ntawv, nws tsuas yog ob hom thermally conductive insulating nplooj ntawv siv rau kev teeb tsa lub zog amplifier fais fab raj (cov khoom siv fais fab), uas yog mica insulating nplooj ntawv thiab silicone (silica gel) insulating nplooj ntawv. Ntawm ob daim ntawv insulating, daim ntawv mica insulating muaj cov yam ntxwv ntawm cov thermal conductivity zoo, siab voltage kuj thiab nyias. Daim ntawv mica insulating hauv daim duab yog {{0}} 06mm nyias thiab 0.13mm tuab. Txawm li cas los xij, vim yog qhov nyuaj ntawm mica insulating daim ntawv, txhawm rau xyuas kom meej tias qhov kev sib cuag ntawm qhov chaw sib raug zoo, nws feem ntau yog siv ua ke nrog cov roj thermal. Lub hom phiaj ntawm kev thov cov roj thermal yog txhawm rau sau qhov khoob uas yuav tshwm sim ntawm qhov chaw sib cuag. Lub thinner lub thermal roj, qhov zoo dua. Nws yog txaus kom flatten tag nrho saum npoo ntawm daim ntawv insulating. Cia peb tham txog silicone (silicone) insulating ntawv. Silicone (silica gel) insulating daim ntawv muaj cov kev ntxhib los mos, muaj zog yas, thiab nws cov kev ua haujlwm insulating tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev txhim kho lub zog amplifier fais fab raj rwb thaiv tsev. Nws tuaj yeem ua tiav yam tsis siv thermal conductive silicone roj thaum lub sijhawm teeb tsa. Txawm li cas los xij, nws yog tuab dua, thiab cov tuab ntawm silicone (silica gel) insulating ntawv yog li 0.3 hli. Rau cov uas xav tau siab, 0.15-cov ntaub ntawv tuab silicone (silica gel) tuaj yeem siv tau. Qhov kev siv li niaj zaus yog tias muaj ntau daim ntawv mica rau triodes thiab cov raj hauv teb, thiab ntau cov ntawv silicone rau lub zog sib xyaw ua ke.
Nws yuav tsum tau muab sau tseg tias mica yuav undergo cleavage nyob rau hauv high kub, yog li nws tsis haum rau kub heev. Muaj ntau hom mica, thiab qhov cleavage kub kuj txawv. Feem ntau, nws yog siv hauv qab kub kub kub.
Taw qhia ntawm cov ntaub ntawv mica:
Cov mica flakes yog tsim los ntawm muscovite, quartz, garnet thiab rutile, ntawm cov albite, zoisite thiab hard chlorite tuaj yeem tshwm sim. Garnet yog nplua nuj hauv Fe thiab Mg, thiab Si hauv muscovite tuaj yeem ncav cuag 3.369. Kuj tseem muaj kev kub siab ua ke. Nws muaj kev ua haujlwm ntawm rwb thaiv tsev thiab tsis tshua muaj thermal tsis kam, thiab nws tseem yog lub cev dub zoo heev.
Mica thiab nws cov khoom siv dav siv los ua cov ntaub ntawv insulating hauv cov khoom siv hluav taws xob. Nws ntau yam yog: ntuj mica, hluavtaws mica, mica daim kab xev, mica phaj, mica foil, mica iav, thiab lwm yam.
