5G xov tooj ntawm tes thermal daws
Muaj ob hom xov tooj cua kub dissipation: nquag thiab passive. Lub tswv yim tseem ceeb yog txo cov thermal tsis kam ntawm lub xov tooj ntawm tes thaum tshav kub kub dissipation (passive heat dissipation) los yog txo cov cua kub ntawm lub xov tooj ntawm tes (active heat dissipation). Active heat dissipation yog paub los ntawm kev txo cov hwj chim noj thiab kub ntawm cov nti, uas muaj feem xyuam rau kev tshawb fawb thiab kev loj hlob ntawm cov khoom siv hluav taws xob.Passive heat dissipation yog tiav los ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Cov khoom uas tsim kom muaj cua sov ntawm lub xov tooj ntawm tes yog feem ntau yog CPU, roj teeb, motherboard, RF pem hauv ntej kawg, thiab lwm yam. cov cua sov uas tsim los ntawm cov khoom siv no yuav nkag mus rau hauv lub interlayer nrog lub peev xwm loj los ntawm lub dab dej kub, thiab tom qab ntawd dissipated los ntawm lub xov tooj ntawm tes. xov tooj plhaub thiab kub dissipation qhov.
Raws li cov khoom siv hluav taws xob ua kom sib zog thiab nyias, lawv lub peev xwm ua kom sov yog txwv vim qhov nqaim sab hauv ntawm lub cev. Cov cua kub tseem ceeb ntawm cov xov tooj ntse suav nrog tsib yam no: kev ua haujlwm nti loj, LCD tsav, roj teeb tso tawm thiab them nyiaj, CCM tsav nti, PCB qauv tsim, tsis sib xws thaum tshav kub kub thiab cua sov dissipation.
Yuav kom daws tau cov teeb meem kub dissipation no, cov thev naus laus zis cua sov hauv khw feem ntau suav nrog cov kev daws teeb meem hauv qab no:
Graphite Sheet Thaum tshav kub kub dissipation:
Feem ntau ntawm cov kev daws teeb meem thermal hauv cov xov tooj ntse siv graphite sheet heat dissipation tsim, tab sis nrog kev nce ntawm cov cua sov dissipation xav tau ntawm cov khoom siv hluav taws xob, cov cua sov ntawm ib txheej lossis ob txheej graphite ntawv tsis tuaj yeem ua tau raws li qhov xav tau ntau dua cov cua kub dissipation.
Graphene tshav kub dissipation:
Graphene muaj thermal conduction zoo heev, thiab nws cov thermal dissipation efficiency yog ntau dua li cov lag luam graphite fins. Graphene tshav kub dissipation zaj duab xis yog nyias nyias, hloov tau thiab zoo heev nyob rau hauv kev ua tau zoo, uas ua rau nws ua tau rau nyias kev loj hlob ntawm cov khoom siv hluav taws xob. Thib ob, graphene tshav kub dissipation zaj duab xis muaj qhov ua tau zoo thiab tuaj yeem sib xyaw nrog lwm cov ntaub ntawv zaj duab xis xws li tsiaj raws li nws daim ntawv thov.
Heatpipe:
Thaum tshav kub kub yeeb nkab yog ib hom kev hloov hluav taws xob uas muaj thermal conductivity. Nws hloov cov cua sov los ntawm evaporation thiab condensation ntawm cov kua nyob rau hauv ib tug tag nrho enclosed lub tshuab nqus tsev yeeb nkab. Hauv kev lag luam xov tooj ntawm tes, nws tseem tuaj yeem hu ua dej txias. Cov yeeb nkab cua sov muaj cov yam ntxwv ntawm kev ua haujlwm siab thiab kev ua haujlwm ntev, uas tau nyiam kev lag luam.
Vapor Chamber:
Vapor Chamberis zoo ib yam li cov yeeb nkab cua sov hauv txoj cai, tab sis nws txawv nyob rau hauv hom conduction. Cov yeeb nkab cua sov yog ib-dimensional linear tshav kub conduction, thaum lub vapor chamber yog ua nyob rau hauv ob-dimensional nto, yog li cov efficiency yog siab dua.
Thermal Pad:
Nws yog cov khoom siv hluav taws xob ua kom sov siab heev. Los ntawm sab, ib tug zoo microporous qauv yog tsim nyob rau hauv cov khoom. Cov qauv microporous no ua rau nws tsis tsuas yog muaj lub zog nqus cua sov ua haujlwm, tab sis kuj tseem muaj cov haujlwm ntawm cov cua sov dissipation!
Kev hloov pauv ntawm Thermal Pad ua rau qhov tsis txaus ntawm cov khoom siv hluav taws xob kub dissipation, kom ua tiav cov txheej txheem tiv thaiv, thiab cov nyhuv yog kaum npaug zoo dua li cov roj thermal zoo tib yam.
