Dab tsi yog qhov txawv ntawm thermal silica gel thiab ceramic heat sink?
Dab tsi yog qhov sib txawv ntawm thermal silica gel thiab ceramic heat sink? Yog hais tias sib tham thiab qhov txawv ntawm qhov kub thiab txias, cov khoom siv hardness, rwb thaiv tsev kev ua tau zoo, thermal conductivity, kev sib txuas ua haujlwm, thiab lwm yam, qhov kev sib txawv tshwj xeeb tau teev raws li hauv qab no. Kev ua tau zoo thiab cov yam ntxwv ntawm thermally conductive silicone ntawv
Qhov kub tsis kam ntawm thermal silica zaj duab xis:
Qhov kub thiab txias ua haujlwm ntau ntawm cov ntawv thermal conductivity silicone yog 200 ° C, tab sis cov dab dej kub ceramic tuaj yeem siv tau ib txwm nyob rau hauv qhov chaw kub siab tshaj 1700 ° C.
Khoom hardness ntawm thermal conductive silicone ntawv:
Thermally conductive silicone daim ntawv yog ib yam ntawm elastic silicone khoom nrog kuj zoo compressibility, thaum ceramic kub dab dej yog ib yam ntawm high-hard ceramic khoom. Nyob rau hauv cov nqe lus ntawm hardness, ceramic kub dab dej yog ntau dua li thermally conductive silicone daim ntawv.
Rwb thaiv tsev kev ua tau zoo ntawm thermally conductive silicone daim ntawv: Qhov tawg voltage ntawm thermally conductive silicone daim ntawv yog 4.5KV / mm, thaum lub breakdown voltage ntawm lub ceramic kub dab dej yog 15KV / mm, thiab lub ntim kuj ntawm ceramic kub dab dej kuj yog siab heev. raws li 1012Ω·m.
Ceramic heat sink kev ua tau zoo thiab cov yam ntxwv:
Thermal conductivity ntawm ceramic kub dab dej:
Lub thermal conductivity ntawm thermally conductive silica gel yog nyob deb inferior rau cov thermally conductive ceramics doped nrog ib tug loj npaum li cas ntawm alumina thiab txhuas nitride. Lub thermal conductivity ntawm alumina ceramic kub dab dej yog ntau tshaj 5 npaug ntawm cov thermally conductive silica gel.
Fitting kev ua tau zoo ntawm ceramic kub dab dej:
Cov rwb thaiv tsev zoo thiab cov khoom muag muag ntawm cov ntawv thermally conductive silicone ua rau nws zoo heev hauv kev ua haujlwm adhesion, thiab nws kuj ua rau nws tsis tshua muaj siv nyob rau hauv tshav kub conduction thiab tshav kub dissipation ntawm daim tawv nqaij ntawm ntau yam khoom siv hluav taws xob, tab sis lub tshav kub hloov ntawm thermally. conductive ceramic daim ntawv yuav tsum tau ib tug npaum li cas ntawm tshav kub conduction. Silicone roj tsub kom nws conformability, uas kuj yog ib qho ntawm cov laj thawj tseem ceeb vim li cas thermally conductive ceramic los xij tsis tau siv dav hauv cov khoom siv hluav taws xob rau kev siv hluav taws xob thiab hluav taws xob.
Txawm hais tias cov khoom siv hluav taws xob ceramic muaj ntau qhov zoo, lawv tsis tuaj yeem hloov thermally conductive silicone pads, ib yam li thermally conductive silicone pads tsis tuaj yeem hloov thermally conductive silicone roj, vim tias txhua cov khoom siv thermally conductive muaj hluav taws xob thermal conductivity daim ntawv thov scenario uas haum rau nws cov yam ntxwv. , Zoo li thermal conductive silicone roj rau desktop computer chips, thermal conductive potting kua nplaum rau sab nraum zoov teeb pom kev zoo, thiab cov ntawv kub-dissipating graphite hauv cov xov tooj ntse.
