Dab tsi yog qhov roughness ntawm insolation board
May 31, 2024
Rwb thaiv tsev boards yog dav siv nyob rau hauv kev tsim kho kev lag luam los muab thermal rwb thaiv tsev thiab txo lub zog noj. Qhov roughness ntawm lub rwb thaiv tsev board yog qhov tseem ceeb hauv kev txiav txim siab nws cov txiaj ntsig. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi roughness yog dab tsi thiab yuav ua li cas nws cuam tshuam qhov kev ua tau zoo ntawm rwb thaiv tsev boards.
Roughness yog hais txog kev ntxhib los mos thiab nto nta ntawm lub rwb thaiv tsev board. Nws tuaj yeem piav qhia siv ntau yam tsis xws li qhov nruab nrab roughness, ncov-rau-kiv qhov siab, thiab thaj chaw saum npoo. Cov kev ntsuas no tuaj yeem ntsuas tau siv ntau yam txuj ci xws li laser scanning, profilometry, thiab microscopy.
Lub roughness ntawm lub rwb thaiv tsev board yog qhov tseem ceeb hauv nws cov thermal ua haujlwm. Ib qho ntxhib saum npoo ua rau thaj chaw sib cuag ntawm lub rooj tsavxwm nrog cov cua nyob ib puag ncig, uas txhim kho cov cua sov hloov mus los ntawm kev sib txuas. Qhov kev hloov pauv cua sov no tuaj yeem txo qhov kev ua tau zoo ntawm cov rwb thaiv tsev thiab ua kom muaj zog siv zog.
Ntawm qhov tod tes, ib tug du nto txo qhov kev sib cuag ntawm lub rwb thaiv tsev board nrog cov huab cua nyob ib puag ncig, uas txo cov cua kub hloov los ntawm convection. Qhov kev txo qis hauv kev hloov hluav taws xob no pab txhim kho cov thermal kev ua tau zoo ntawm lub rwb thaiv tsev board, uas ua rau txo qis zog noj thiab txhim kho kev nplij siab.
Txhawm rau kom ua tiav qhov kev ua haujlwm zoo thermal, qhov roughness ntawm lub rwb thaiv tsev yuav tsum tau ua tib zoo tswj. Cov neeg tsim khoom siv ntau yam txuj ci xws li xuab zeb, polishing, thiab txheej kom ua tiav qhov xav tau ntawm qhov roughness. Qhov kev xaiv ntawm cov txheej txheem yog nyob ntawm hom rwb thaiv tsev board, qhov xav tau kev ua tau zoo, thiab tus nqi.
Hauv kev xaus, qhov roughness ntawm lub rwb thaiv tsev board yog qhov tseem ceeb hauv kev txiav txim siab nws cov txiaj ntsig. Qhov rougher ntawm qhov chaw, qhov siab dua cov cua sov hloov los ntawm convection, uas txo cov thermal kev ua tau zoo ntawm lub rwb thaiv tsev board. Ntawm qhov tod tes, smoother nto txhim kho cov thermal kev ua tau zoo, uas ua rau txo qis zog noj thiab txhim kho kev nplij siab. Cov neeg tsim khoom siv ntau cov tswv yim los tswj qhov roughness ntawm rwb thaiv tsev boards kom ua tiav qhov kev xav tau ntawm tus nqi qis tshaj.
