Txoj kev loj hlob ntawm cov yeeb nkab cua sov thiab vapor chamber kev lag luam
Nrog kev txhawb nqa txuas ntxiv ntawm 5G kev tsim kho, 5G lub hauv paus chaw nres tsheb thiab cov servers yuav nqa cov ntaub ntawv loj thiab kev xa mus. Kev nce hauv kev siv hluav taws xob ua haujlwm tau ua rau qhov teeb meem kub dissipation tseem ceeb heev. Nyob rau tib lub sijhawm, nrog kev txhim kho txuas ntxiv ntawm cov khoom siv hluav taws xob txuas mus rau lub teeb yuag thiab kev ua haujlwm ntau yam, kev tsim cov cua sov thiab cov cua kub dissipation xav tau ntawm ntau yam khoom siv hluav taws xob sab hauv kuj tau nce ntxiv.
Tam sim no, nrog rau cov thermal conductivity zoo heev, qhov nkag mus ntawm cov kav dej kub thiab cov phaj kub sib npaug hauv ntau yam khoom siv hluav taws xob xws li 5G kev sib txuas lus, servers, smartphones, laptops, projectors, thiab lwm yam. Nyob rau hauv lub neej yav tom ntej, qhov chaw ua lag luam muaj feem xyuam yuav tsum tau txuas ntxiv.
Nrog rau kev ua kom pom tseeb thiab thinness ntawm cov khoom siv hluav taws xob, qhov chaw sab hauv ntawm cov khoom tau dhau los ua me thiab kev sib koom ua ke ntawm cov khoom siv sab hauv yog siab dua. Thermal conductive thiab heat dissipation cov ntaub ntawv los yog cov khoom yuav tsum ua kom tau zoo dua thermal conductive thiab kub dissipation functions nyob rau hauv ib tug nqaim lub cev qhov chaw. Thermal conductive thiab tshav kub dissipation tuam txhab yuav tsum tau txuas ntxiv txhim kho lawv cov txheej txheem thev naus laus zis txhawm rau txhim kho kev ua tau zoo dua thiab cov khoom siv thermal precision.
Sib piv cov thermal conductivity ntawm cov ntaub ntawv sib txawv, nws tau pom tias thermal conductivity ntawm cov kav dej kub thiab cov vapor chamber yog ze li kaum npaug ntawm cov khoom siv graphite. Ntawm cov kav dej kub thiab vapor chamber s, cov thermal conductivity ntawm cov hlau tsis sib xws yog siab dua. Yog li ntawd, qhov zoo ntawm cov kav dej kub thiab cov pa kub sib txawv ntawm cov pa vapor chamber yog qhov pom tseeb dua. Tsis tas li ntawd, cov kav dej kub muaj nyob rau hauv ib-dimensional linear tshav kub conduction, thaum lub tshuab nqus tsev kub daim hlau muab ob-dimensional conduction qhov chaw, ua rau muaj kev ua tau zoo dua. Tshwj xeeb, cua sov yog absorbed los ntawm cov kua nyob rau hauv qab ntawm lub vapor chamber, ces evaporated thiab diffused mus rau hauv lub tshuab nqus tsev chamber, coj lub tshav kub mus rau lub dab dej kub, thiab ces condensed rau hauv ib tug kua rov qab mus rau hauv qab. Lub hauv paus ntsiab lus ntawm cov cua kub dissipation no zoo ib yam li cov txheej txheem evaporation thiab condensation ntawm lub tub yees cua txias.
Nyob rau hauv lub neej yav tom ntej, nrog kev tshwm sim ntawm high-power khoom thiab cov kev hloov pauv ntawm kev lag luam, qhov kev thov rau high-efficiency cua sov kav thiab vapor chamber nyob rau hauv kev ua lag luam yuav ho nce, thiab ntau lawm yuav tsum tau muab tso rau pem hauv ntej. Qhov no yuav txhawb kev txhim kho cov khoom siv thermal kom zoo dua thiab ua haujlwm zoo, uas yog qhov tsim nyog rau kev noj qab haus huv thiab kev noj qab haus huv ntawm kev lag luam.
