Gulu la pepala la graphite

Pepala la graphite limadutsa m'njira zingapo zowonjezera monga graphite yapamwamba ya phosphorous pepala, mankhwala opangira mankhwala, kuwonjezereka kwa kutentha kwakukulu ndikuwotcha. Ili ndi kukana kutentha kwakukulu, kuwongolera kutentha, kusinthasintha, kulimba mtima komanso ntchito yabwino yosindikiza. Mapepala a graphite ali ndi makhalidwe abwino kwambiri. Malinga ndi ntchito yake, ikhoza kugawidwa kukhala kusindikizapepala la graphite, matenthedwe conductive graphite pepala ndi conductive graphite pepala.
1. Pepala la graphite kuti asindikize
Zakhala zikugwiritsidwa ntchito kwambiri mu mphamvu zamagetsi, makampani opanga mankhwala, zida, makina ndi mafakitale ena. Itha kusintha zisindikizo zachikhalidwe monga mphira ndi asibesitosi ndikugwiritsidwa ntchito ngati zisindikizo zosunthika zamakina, mapaipi, mapampu ndi mavavu.
2. Kutentha kuchititsa pepala la graphite
Thermal conductive graphite paper imakhala ndi matenthedwe abwino kwambiri komanso magwiridwe antchito a kutentha. Amagwiritsidwa ntchito kwambiri m'mafoni am'manja, ma laputopu ndi zinthu zina zamagetsi.
3. Mapepala a graphite conductive
Amagwiritsidwa ntchito popanga ndi kukonza zinthu zosiyanasiyana za conductive.

Mfundo ndikugwiritsa ntchito mafakitale a pepala la graphite

Mfundo yoyendetsera kutentha kwa pepala la graphite ndi yakuti kutentha kwakukulu ndi kutentha kumapangitsa kutentha mofanana m'mbali ziwiri za pepala la graphite. Pepala la graphite limatha kuyamwa mbali ya kutentha ndikuchotsa kutentha kudzera mumayendedwe a kutentha pamwamba pa pepala la graphite, lomwe limagwira ntchito yochotsa kutentha. The yopingasa matenthedwe madutsidwe pepala graphite zambiri pakati w / mk ndi ofukula matenthedwe madutsidwe ndi pakati 10-20w / mK, The matenthedwe madutsidwe mwachindunji mogwirizana ndi mtengo wa graphite pepala.

Poyerekeza ndi zida zachitsulo zachikhalidwe, kutenthetsa kwa pepala la graphite ndi 3 ~ 5 nthawi zamkuwa ndi aluminiyamu.Mapepala owonda kwambiri a graphitenthawi zambiri amagwiritsidwa ntchito popangira kutentha kwa zida zamagetsi. Ultra woonda graphite ali otsika matenthedwe kukana, 40% m'munsi kuposa aluminiyamu ndi 20% m'munsi kuposa mkuwa. Mapepala a graphite amatha kudulidwa mumitundu yosiyanasiyana, ndipo pepala la graphite la kutentha lingagwiritsidwe ntchito pochotsa kutentha kwa zida zamagetsi.
