Lub luag haujlwm ntawm cov khoom siv thermal conductive yog dab tsi?

Cov ntaub ntawv thermal conductive yog tsim thiab tsim kom tau raws li qhov xav tau ntawm cov khoom siv thermal conductivity, nrog rau kev ua tau zoo thiab kev ntseeg siab. Lawv tsim nyog rau ntau qhov chaw thiab cov kev xav tau, thiab muaj cov kev daws teeb meem tsim nyog rau cov teeb meem kub dissipation. Lawv muab kev pabcuam muaj zog rau kev sib koom ua ke siab ntawm cov khoom siv thiab tsim cov khoom siv ultra me me thiab ultra-nyias.
Muaj qhov tsis sib xws zoo heev ntawm qhov chaw ntawm cov ntaub ntawv microelectronic thiab lub dab dej kub. Yog tias lawv raug ntsia ncaj qha ua ke, qhov chaw sib cuag ntawm lawv tsuas yog 10% ntawm thaj chaw hauv paus ntawm lub dab dej kub, thiab qhov seem yog cov pa tawm. Vim tias cov thermal conductivity ntawm huab cua tsuas yog 0.024W / (m · K), nws yog qhov tsis zoo ntawm cov hluav taws xob hluav taws xob, uas yuav ua rau muaj kev sib cuag loj heev ntawm cov khoom siv hluav taws xob thiab cov dab dej kub, ua rau muaj kev cuam tshuam loj heev ntawm cov hluav taws xob hluav taws xob. thaum kawg ua rau qis efficiency ntawm lub dab dej kub.
Sau cov qhov khoob no nrog cov khoom siv thermal conductivity thermal interface, tshem tawm cov huab cua los ntawm lawv, thiab tsim kom muaj cov thermal conduction zoo ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tuaj yeem txo qhov kev tiv thaiv thermal thiab siv tag nrho cov dej ua haujlwm ntawm lub dab dej kub.
Cov khoom siv thermal zoo tagnrho yuav tsum muaj cov yam ntxwv hauv qab no:
(1) High thermal conductivity
(2) Kev hloov pauv siab thiab tawv kom ntseeg tau tias cov khoom siv thermal interface tuaj yeem ua tiav qhov khoob ntawm qhov chaw sib cuag hauv qab kev teeb tsa siab, kom ntseeg tau tias kev sib cuag thermal ntawm cov khoom siv thermal interface thiab qhov chaw sib cuag me me;
(3) Cov khoom siv rwb thaiv tsev;
(4) Yooj yim rau nruab thiab tshem tawm;
(5) Siv tau dav, nws tuaj yeem siv los sau cov qhov khoob me me nrog rau qhov khoob loj.
