Omusingi gw’Ebikozesebwa

Grafayiti ya flake ey’obutambuzi obw’ebbugumu-ya waggulu ekolebwa okuva mu graphite ya flake ey’obutonde okuyita mu kulongoosa n’okubumba (oba okulongoosa mu ddaala lya pawuda-). Ensengekera yaayo ey’enjawulo eya layeri efuna obutambuzi bw’ebbugumu obw’enjawulo-omuwendo gwayo ogw’omusingi. Etuwa "okutambuza ebbugumu mu ngeri ey'obulungi ennyo, okufiirwa kw'amasoboza okutono, okugonjoola ebbugumu okukyukakyuka mu mbeera nnyingi, okugonjoola ensonga z'ebintu eby'ebyuma (ekikomo, aluminiyamu) eby'omuwendo omunene/obungi n'okuvvuunuka obutambuzi bw'ebbugumu obunafu obw'ebyuma ebitali{8}}ebyuma, mu ngeri ennungi okujjuza ebituli mu katale.

Ebipimo by'ebyekikugu(Ebintu biwagira okulongoosa omuntu ku bubwe)

Ebintu Ebikulu (Essira liteekeddwa ku butambuzi bw’ebbugumu-Eby’obugagga ebikwatagana)

① Anisotropic Obutambuzi bw’ebbugumu obw’amaanyi

Ensengekera yaayo eya layeri (efaananako ne "stacked thermal conductive sheets") evaamu okusinga nnyo mu-plane thermal conductivity okusinga cross{1}}plane performance. Munda mu buli layeri, High Thermal Conductivity Flake Graphite mangu-nga yeewaanira ku bulungibwansi bw’ebbugumu emirundi 20-50 okusinga obwa resin ez’ennono. Mu kiseera kino, obutambuzi bw'ebbugumu obw'okusalako ennyonyi busobola okulongoosebwa nga bwe kyetaagisa, ekigifuula ennungi ennyo mu mbeera za "okusaasaanya ebbugumu mu ngeri ey'obulagirizi" (okugeza, okufuga ebbugumu mu kitundu ky'ebitundu by'obusannyalazo).

2 Okuziyiza ebbugumu okutono & Okutebenkera okunene

Kiraga obuziyiza bw’ebbugumu obutono ennyo (<=0.15 K·m2/W) mu kiseera ky’okutambuza ebbugumu. Ekirala, mu bbugumu eriri wakati wa -200℃okutuuka ku 600℃, obutambuzi bwayo obw’ebbugumu busigala kumpi nga tebukyuse, nga tewali kusaanuuka oba kuvunda. Okutebenkera kuno kusobozesa okukola okwesigika mu mbeera ez’ebbugumu eringi ennyo-n’ery wansi.

3 Kizitowa & Kyangu okukola

Olw’obuzito bwa g/cm3 2.2-2.3 zokka (nga 1/4 obw’ekikomo ne 2/3 obwa aluminiyamu), esobola okulongoosebwa n’efuuka pawuda, firimu ennyimpi, gaasikiti, n’engeri endala. Ekwatagana bulungi n’ebintu ebitali bituufu (nga chips z’ebyuma ne tabs za bbaatule) era ewagira okugiteeka mu ngeri ekyukakyuka.

4 Obulongoofu bwa waggulu & Obucaafu obutono

Obulongoofu bwa grafayiti butuuka ku Kisinga oba obwenkana ebitundu 95% (nga buli -obulongoofu obutuuka ku 99.95%), era evvu eriri Kitono oba lyenkana 0.5%. Obutabeerawo bucaafu bwa kyuma kimalawo okutaataaganyizibwa mu kkubo ly’okutambuza ebbugumu, ne kiziyiza okweyongera kw’obuziyiza bw’ebbugumu mu kitundu oba okukulukuta kw’amasannyalaze-okukifuula su

Ebbugumu-Enkola ezigenderera okutambuza-Ebikozesebwa (Big Data-Ebivugibwa Waggulu-Ebifaananyi bya Frequency)

1 Amakolero g’Ebyuma/Semiconductor: Okusaasaanya ebbugumu mu ndagiriro

CPU Heat Sinks ku masimu/Laptops: Flake graphite ekolebwa mu firimu ezitambuza ebbugumu ezigonvu ennyo (obuwanvu bwa mm 0.05-0.5), ezinywerera ku bitundu bya chip. Ekyusa mangu ebbugumu mu biwaawaatiro bya heat sink, okuziyiza chip okubuguma ennyo n’okuziyiza frequency.

Ebintu ebitambuza ebbugumu okusobola okutaasa LED: Butto wa flake graphite atabulwa ne ceramics/resins okukola substrates ezitambuza ebbugumu, okudda mu kifo kya substrates za aluminiyamu ez’ennono. Kino kyongera ku bulungibwansi bw’okusaasaanya ebbugumu mu kutaasa era kyongera ku bulamu bwa LED ebitundu ebisukka mu 30%.

2 Battery z’amasoboza empya: Enzirukanya y’ebbugumu

Pads z'ebbugumu eza bbaatule z'amaanyi: Gaasikiti za flake graphite ziteekebwa wakati wa modulo za bbaatule. Mu kiseera ky’okucaajinga n’okufulumya, High Thermal Conductivity Flake Graphite mu ngeri ennungi, okukyusa ebbugumu erya waggulu erya localized okudda mu nkola y’okunyogoza mu bwangu n’okuziyiza ebbugumu okudduka.

Ebizigo ebitambuza ebbugumu ku Taabu za Battery: Butto wa flake graphite akolebwa mu bizigo ebitambuza-bbugumu, nga bisiigibwa ku bitundu bya tabu. Kino mu kiseera kye kimu kilongoosa okutambuza obusannyalazo n’okutambuza ebbugumu obulungi, okukendeeza ku bbugumu lya bbaatule okulinnya mu kiseera ky’okucaajinga/okufulumya (<=5℃).

3 Ebyuma by’amakolero: Okutambuza/okuziyiza ebbugumu ery’ebbugumu eringi-

Layers z’okutambuza ebbugumu ku Linings z’ekikoomi ez’ebyuma: High-purity flake graphite ekolebwa mu matoffaali era n’eteekebwa ku bisenge eby’omunda eby’ekikoomi ky’ebyuma. Kyanguya okutambuza ebbugumu munda mu kyokero, okutuuka ku kugabanya kw’ebbugumu okwa kimu (okukendeeza ku njawulo z’ebbugumu mu kitundu ne diguli 10-15 ).

Okuziyiza Payipu/Ebbugumu-Ebikozesebwa mu Kulondoola: Butto wa flake graphite atabulwa ne insulating resins okukola ebintu ebibikka payipu. Kikendeeza ku kufiirwa ebbugumu ku bbugumu eri wansi (insulation) era kyanguyiza okutambuza ebbugumu mu ngeri y’emu ku bbugumu erya waggulu (okulondoola ebbugumu), ekisaanira payipu z’eddagala n’ebbugumu.

4 Amakolero g’emmotoka: Okunyogoza ebitundu

Thermal Pads za Motors Empya ez'amaanyi: Paadi za flake graphite ziteekebwa wakati w’ebisenge bya mmotoka n’enkola ezinyogoza. Zisaasaanya mangu ebbugumu erikolebwa mu nkola ya mmotoka, ne zirongoosa enkola ya mmotoka n’okukendeeza ku maanyi agakozesebwa ebitundu 5%-8%.

Ku-Okusaasaanya ebbugumu mu chajingi ya bboodi (OBC).: Firimu za flake graphite ziyungibwa ku ngulu w’ebitundu bya OBC eby’omunda, ne zigonjoola ensonga z’ebbugumu eringi-mu kiseera ky’okucaajinga amangu n’okukakasa obukuumi bw’okucaajinga.

Okubumbako

Eno high-thermal-conductivity flake graphite ekozesa ensengekera yaayo eya anisotropic, okutambuza ebbugumu okw’ekika ekya waggulu, dizayini ennyangu, n’okutebenkera okw’enjawulo. Kikola ng’ekintu ekikulu eky’okuddukanya ebbugumu mu bitundu byonna eby’ebyuma, amaanyi amapya, amakolero, n’emmotoka, nga kikola ku bintu ebikulu ebiruma ng’okusaasaanya ebbugumu mu ngeri etali nnungi, ebitundu ebizito, n’obutabeera mu ntebenkevu obw’ekitalo mu butonde.
