ceramics heatsink txias rau cov khoom siv hluav taws xob

Thaum Lub Xya Hli 2021, cov kws tshawb fawb tab tom sim ib qho kev sim ceramic compound. Thaum raug kev hloov pauv huab cua thiab kev siv tshuab siab, ceramics yooj yim tawg lossis tawg vim thermal shock. Thaum koj txau cov ceramics nrog lub tshuab blowtorch, nws deforms. Tom qab ob peb qhov kev sim, cov kws tshawb fawb pom tau tias lawv tuaj yeem tswj nws qhov deformation. Yog li ntawd lawv pib compress cov ntaub ntawv ceramic thiab pom tias cov txheej txheem no tau nrawm heev.

Lub microstructure ntawm cov txheej hauv qab tso cai rau tag nrho cov ceramics hloov cov cua sov sai sai thaum lub sij hawm tsim, thiaj li ua tau zoo thaum tshav kub kub txaus. Cov kws tshawb fawb tau hais tias hom ceramics no tuaj yeem tsim cov duab geometric ilv thiab nthuav tawm cov khoom siv zoo heev thiab thermal conductivity ntawm chav tsev kub. Hom kub tsim ceramics no yog cov ntaub ntawv tshiab.

Cov khoom tshiab no yuav ua rau ob qho kev txhim kho kev lag luam. Ua ntej, nws muaj kev ua haujlwm siab ua cov thermal conductor, uas tuaj yeem txias cov khoom siv hluav taws xob high-density. Feem ntau hais lus, cov xov tooj ntawm tes thiab lwm yam khoom siv hluav taws xob tau teeb tsa nrog cov txheej txheej tuab tuab, uas yog tsim nyog los nqus cov cua sov los ntawm cov khoom siv. Cov khoom siv tshiab yog tsawg dua ib millimeter tuab thiab tuaj yeem ua pwm rau hauv qhov yuav tsum tau ua kom txias.

Lwm qhov kev txhim kho yog tias nws tuaj yeem ncaj qha rau cov duab ntawm cov khoom siv hluav taws xob. Cov kws tshawb fawb tau pom qhov tsis yog Newtonian tus cwj pwm ntawm cov ceramic no. Lawv liquefied ib pob ntawm cov ceramic slurry los ntawm kev co, thiab reorganized cov qauv ntawm cov khoom rau hauv moldable ceramic.

Cov kws tshawb fawb ntseeg tias txhua yam khoom siv ceramic no tuaj yeem siv rau kev tsim thiab kev sib txuas rau ntau yam khoom siv hluav taws xob yav tom ntej. Cov ceramic no yuav nyias, sib dua thiab ua haujlwm zoo dua li cov hlau siv tam sim no.
