Raws li tus neeg muag khoom ntawm Graphite Thermal Sheets, Kuv tau pom ua ntej qhov kev thov loj hlob rau kev tswj xyuas thermal zoo thoob plaws ntau yam kev lag luam. Ib qho ntawm cov khoom tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm cov ntawv no yog lawv cov peev txheej tshwj xeeb. Hauv cov ntawv blog no, kuv mam li piav qhia txog yuav ua li cas lub peev xwm tshwj xeeb ntawm Graphite Thermal Sheets cuam tshuam rau lawv lub peev xwm hloov hluav taws xob, tshawb txog cov kev tshawb fawb hauv qab thiab cov kev cuam tshuam.
Nkag siab txog qhov muaj peev xwm kub
Ua ntej peb dhia mus rau hauv kev sib raug zoo ntawm cov peev txheej tshwj xeeb thiab kev hloov hluav taws xob, cia peb ua ntej kom meej meej tias lub peev xwm tshwj xeeb yog dab tsi. Lub peev xwm kub tshwj xeeb, feem ntau txhais tau tias yog "c," yog qhov ntsuas kub ntawm lub zog yuav tsum tau nce qhov kub ntawm ib chav tsev ntawm cov khoom los ntawm ib qho℃Celsius (los yog Kelvin). Nws yog ib qho tseem ceeb ntawm cov ntaub ntawv thiab qhia nyob rau hauv units ntawm joules ib kilogram ib℃Celsius (J / kg℃).
Cov ntaub ntawv sib txawv muaj peev xwm sib txawv ntawm cov cua sov, uas txhais tau hais tias lawv nqus thiab tso cua sov ntawm cov nqi sib txawv. Piv txwv li, dej muaj qhov tshwj xeeb kub muaj peev xwm ntawm 4,186 J / kg degree, uas txhais tau hais tias nws tuaj yeem nqus tau ntau lub zog cua sov yam tsis muaj qhov kub thiab txias. Ntawm qhov tod tes, cov hlau feem ntau muaj qis dua qhov tshwj xeeb cua sov, tso cai rau lawv kom sov thiab txias dua sai dua.
Tshwj xeeb kub muaj peev xwm ntawm Graphite Thermal Sheets
Graphite yog cov khoom siv tshwj xeeb nrog cov khoom siv thermal zoo, nrog rau cov thermal conductivity thiab muaj peev xwm ua kom sov tsawg. Qhov tshwj xeeb kub muaj peev xwm ntawm graphite feem ntau yog li ntawm 700 txog 1,000 J / kg degree, nyob ntawm nws cov purity, qauv, thiab lwm yam. Qhov no kuj tsis tshua muaj hluav taws xob muaj peev xwm txhais tau tias graphite tuaj yeem nqus tau thiab tso tawm lub zog hluav taws xob sai, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv thermal tswj.
Kev cuam tshuam rau Kev Hloov Kho Kub Kub
Qhov tshwj xeeb kub muaj peev xwm ntawm Graphite Thermal Sheets plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab lawv lub peev xwm hloov hluav taws xob. Nov yog li cas:
1. Kev nqus cua sov sai
Vim lawv lub peev xwm tshwj xeeb tsis tshua muaj cua sov, Graphite Thermal Sheets tuaj yeem nqus tau cov cua sov los ntawm qhov cua sov sai. Thaum muab tso rau hauv kev sib cuag nrog cov khoom kub, xws li CPU lossis lub zog transistor, daim ntawv graphite tuaj yeem nqus cov cua sov sai sai thiab faib nws thoob plaws nws qhov chaw. Qhov no pab tiv thaiv cov tivthaiv los ntawm overheating thiab ua kom nws cov kev ua tau zoo.
2. Ua kom muaj cua sov zoo
Thaum tshav kub yog absorbed los ntawm Graphite Thermal Sheet, nws yuav tsum tau dissipated zoo kom tswj tau qhov kub thiab txias. Qhov tshwj xeeb kub muaj peev xwm ntawm graphite tso cai rau nws tso tawm cov hluav taws xob nqus hluav taws xob sai sai, ua kom yooj yim rau cov cua sov dissipation. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas yuav tsum tau muab tshem tawm sai sai, xws li hauv cov khoom siv hluav taws xob siab -.
3. Kev ruaj ntseg kub
Qhov tshwj xeeb kub muaj peev xwm ntawm Graphite Thermal Sheets kuj ua rau qhov kub thiab txias. Los ntawm kev nqus thiab tso tawm lub zog hluav taws xob sai sai, daim ntawv graphite pab tswj qhov kub thiab txias ntawm cov cua sov thiab tiv thaiv qhov kub thiab txias. Qhov no yog qhov tseem ceeb rau kev tswj xyuas kev ntseeg tau thiab kev ua haujlwm ntev ntawm cov khoom siv hluav taws xob, vim tias qhov kub thiab txias ntau dhau tuaj yeem ua rau thermal stress thiab puas.
Daim ntawv thov ntawm Graphite Thermal Sheets
Kev sib xyaw tshwj xeeb ntawm cov cua kub tshwj xeeb thiab cov thermal conductivity siab ua rau Graphite Thermal Sheets haum rau ntau yam kev siv, suav nrog:
