Thermal ntaub yog ib feem tseem ceeb thaum nws los txog rau cua sov dissipation hauv cov khoom siv hluav taws xob. Lawv ua ib qho kev sib tshuam ntawm cov cua sov thiab cov hluav taws xob hluav taws xob yog li nce lub thermal conductivity ntawm cov khoom siv no. Cov hnub no, thermal ncoo tau siv dav hauv kev lag luam xws li kev lag luam computer, tshuab hluav taws xob Aerospace, thiab lwm yam.
Thermal ntaub lossis thermal interface cov ntaub qhwv tau tsim los muab hluav taws xob rwb thaiv tsev raws li kev ua hluav taws xob xws li cov txheej txheem thiab cua sov. Lawv muaj pes tsawg leeg yog raws cov ntaub ntawv xws li silicone, txhuas oxide ceramics, lossis graphite. Los ntawm cov neeg siv khoom siv, cov khoom tseem ceeb tshaj plaws ntawm cov ntaub ntawv yog lawv cov cua nab kuab, tuab, thiab coefficient ntawm thermal expansion.
Thermal kev kawm yog ib qho ntawm cov tseem ceeb tshaj plaws thaum nws los txog rau thermal ntaub. Hauv cov khoom siv hluav taws xob, thermal conductivity yog qhov tseem ceeb tshaj plaws rau kev txiav txim siab vim nws txhais tau tias ceev ceev npaum li cas cov kev hloov pauv ntawm ib qho. Ntau dua kev coj ua yuav sib npaug rau lub peev xwm ntau dua rau kev ua kom sov.
Lwm yam tseem ceeb los txiav txim siab suav nrog cov tuab tuab thiab coefficient ntawm thermal expansion. Thickness yog qhov tseem ceeb vim tias nws txiav txim siab qhov sib txawv uas cov kev hloov pauv ntawm cov pa hluav taws xob yuav qhia tau qhov loj me uas tej zaum yuav tshwm sim thaum raug cov kev hloov pauv kub.
Kev lig kev cai, muaj peb hom sib txawv ntawm thermal pads uas feem ntau siv. Cov no yog; Silicon -} based thermal bads, graphite {2} - based thermal pads. Silicon - borial} Raws cov ntaub yog nrov vim tias lawv muaj cov hluav taws xob tsis zoo thiab yog hluav taws xob tsis-.
Graphite -} based thermal bulls yog qhov tseem ceeb vim graphite cov thermal conductivity yog qhov siab dua piv rau lwm txoj kev sib txuas. Thaum kawg, ceramic - bath based thermal terms yog qhov zoo vim tias lawv muaj qhov siab dua thermal conductivity thiab tuaj yeem tiv siab ntau zaus. Lawv tshwj xeeb zoo -} haum rau cov khoom siv hluav taws xob nrog cov khoom kub siab dua.
Thermal ntaub nrhiav lawv siv nyob rau hauv ntau daim ntawv thov hluav taws xob xws li:
- CPUs rau cov servers thiab pcs
- coj teeb pom kev zoo
-} Cov Khoom Siv Industrial
-} cov khoom siv kho mob
-} Kev Siv Hluav Taws Xob Hluav Taws Xob
Hauv cov ntsiab lus xaus,Thermal padsyog qhov tseem ceeb ntawm cov khoom siv hluav taws xob uas ua kom muaj kev kub ntxhov kub ntxhov. Peb lub npe tseem ceeb yog silicone - raws li cov duab, thiab cov ceramic- raws li cov ntaub qhwv. Cov no tau ua haujlwm hauv ntau qhov kev lag luam uas cuam tshuam nrog cov khoom siv hluav taws xob. Nws yog ib qho tseem ceeb uas yuav tsum tau txiav txim siab xws li thermal conductivity, coeffal kev nthuav dav, thiab tuab raws li lawv txoj haujlwm tag nrho thaum xaiv lub ncoo. Kev xaiv ntawm qhov zoo tshaj plaws thermal ncoo rau koj cov khoom siv yuav muab kev ua tau zoo dua, kev ntseeg tau, thiab thiav.
