Imiba enguNdoqo (eJoliswe kwi-Thermal Conductivity{0}}Iimpawu eziNxulumeneyo)

① I-Anisotropic High Thermal Conductivity

Ulwakhiwo olunomaleko (olufana "namashiti apakishiweyo e-thermal conductive") iziphumo ziphezulu kakhulu-kwindlela yokuhanjiswa kwe-thermal yeplane kunokusebenza{1}}kwenqwelomoya. Ngaphakathi komaleko ngamnye, iHigh Thermal Conductivity Flake Graphite ngokukhawuleza-iqhayisa ngokusebenza kakuhle kwe-thermal 20-50 amaxesha entlaka zesintu. Okwangoku, i-cross-plane conductivity ye-thermal conductivity inokulungelelaniswa njengoko ifuneka, iyenze ilungele iimeko "ze-directional heat dissipation" (umzekelo, ulawulo lobushushu bendawo yamalungu e-elektroniki).

② Ukuchasana kweThermal ephantsi kunye nokuzinza okuphezulu

Ibonisa ukuxhathisa kobushushu obuphezulu-(Ngaphantsi okanye ilingana ne-0.15 K·m²/W) ngexesha lokudluliselwa kobushushu. Ngaphezu koko, phakathi koluhlu lweqondo lobushushu -200℃ukuya 600 degree, conductivity yayo thermal kuhlala phantse ingaguquki, akukho ukunyibilika okanye ukubola. Oluzinzo luvumela ukusebenza okuthembekileyo kwindawo ephezulu kakhulu{7}kunye nobushushu obuphantsi.

③ Ikhaphukhaphu kwaye kulula ukuyiqhuba

Ngoxinaniso lwe-2.2-2.3 g/cm³ kuphela (malunga ne-1/4 leyo yobhedu kunye ne-2/3 ye-aluminiyam), inokucutshungulwa ibe ngumgubo, iifilimu ezibhityileyo, iigaskets, kunye nezinye iifom. Ihambelana ngokugqibeleleyo neendawo ezingaqhelekanga (ezifana neetshiphusi ze-elektroniki kunye neethebhu zebhetri) kwaye ixhasa ukufakela okuguquguqukayo.

④ Ukucoceka okuphezulu kunye nokungcola okuphantsi

Ubunyulu beGraphite bufikelela kuMkhulu okanye bulingana no-95% (namabanga aphezulu{1}}ococeko ukuya kuthi ga kwi-99.95%), kwaye umxholo wothuthu ungaphantsi okanye ulingana no-0.5%. Ukungabikho kobumdaka besinyithi kuphelisa ukuphazamiseka kwindlela yokuqhuba i-thermal, kuthintela ukonyuka kokumelana ne-thermal yendawo okanye i-electrochemical corrosion{5}}iyenza ibe lula.
