Ibicuruzwa

Hejuru - ubushyuhe - itwara flake grafitike ikorwa muri grake ya flake isanzwe binyuze mu kweza no kubumba (cyangwa ifu - gutunganya amanota). Imiterere yihariye yububiko itanga ubushyuhe budasanzwe - agaciro kayo. Itanga "hejuru - ihererekanyabubasha ryiza, gutakaza ingufu nke, byinshi - ibintu bishobora guhinduka" ibisubizo byubushyuhe bwumuriro, gukemura ibikoresho byuma "(umuringa, aluminium) ibiciro byigiciro / ubucucike no gutsinda gakondo itari - ibyuma byubushyuhe buke bwumuriro, bikuzuza neza icyuho cyamasoko.

Ibipimo bya tekiniki (Ibicuruzwa bishyigikira kugiti cyawe)

Icyiciro cya Parameter	Agaciro Urwego	Ibisobanuro
Amashanyarazi	10-120 W/(m·K)	Indangagaciro zisumbuye zerekana imbaraga zikomeye zumuriro; hitamo amanota ukurikije ibyifuzo bikenewe (urugero, hejuru - ibikoresho bya elegitoroniki ya 80-120 W / (m · K)).
Ubucucike	2.2-2.3 g / cm³	Birakwiriye kubishushanyo mbonera byoroheje mubikoresho bya elegitoroniki ninganda zitwara ibinyabiziga.
Gukoresha Ubushyuhe	Impamyabumenyi ya 200 kugeza kuri dogere 600	Imikorere ihamye murwego; irinde guhura nubushyuhe buri hejuru ya dogere 600 mukirere kugirango wirinde okiside.
Kurwanya Ubushyuhe	Ntibiri cyangwa bingana na 0.15 K · m² / W.	Iremeza gutakaza ingufu nkeya mugihe cyo kohereza ubushyuhe.
Igishushanyo cyera	Kurenza cyangwa bingana na 95% (Hejuru {{1} grade Icyiciro cyera: Ikiruta cyangwa kingana na 99,95%)	Kurenza cyangwa bingana na 99% byera bisabwa kuri electronics / bateriyeri kugirango wirinde kwivanga.
Ibirimo ivu	Ntibiri munsi cyangwa bingana na 0.5%	Bifitanye isano no kweza; Ntibiri munsi cyangwa bingana na 0.1% byasabwe hejuru - byuzuye bya semiconductor progaramu.

Ibiranga Ibyingenzi (Yibanze ku mikorere yubushyuhe - Ibyiza bifitanye isano)

① Anisotropic Yubushyuhe Bwinshi

Imiterere yacyo (igereranywa n "" urupapuro rwerekana ubushyuhe bwumuriro ") itanga ibisubizo hejuru cyane muri - indege yubushyuhe bwindege kuruta umusaraba - imikorere yindege. Muri buri cyiciro, Ubushyuhe Bwinshi bwa Flake Graphite yihuta - kwirata ubushyuhe bwumuriro inshuro 20 - inshuro 50 zubwa gakondo. Hagati aho, ubushyuhe bw’umuriro bwambukiranya indege burashobora guhuzwa nkuko bikenewe, bigatuma biba byiza kuri "icyerekezo cyo gukwirakwiza ubushyuhe" (urugero, kugenzura ubushyuhe bwibanze bwibikoresho bya elegitoroniki).

② Kurwanya Ubushyuhe Buke & Guhagarara neza

Irerekana ultra - irwanya ubushyuhe buke (Ntibiri cyangwa bingana na 0.15 K · m² / W) mugihe cyo kohereza ubushyuhe. Byongeye kandi, mubushyuhe bwa dogere - 200 kugeza kuri dogere 600, ubushyuhe bwayo bwumuriro ntigihinduka hafi, nta gushonga cyangwa kubora. Uku gushikama gutuma imikorere yizewe murwego rwo hejuru - hamwe nubushyuhe buke.

Umucyo woroshye & Byoroshye gutunganya

Hamwe n'ubucucike bwa 2,2-2.3 g / cm³ gusa (hafi 1/4 cy'umuringa na 2/3 bya aluminium), irashobora gutunganyirizwa mu ifu, firime yoroheje, gasketi, n'ubundi buryo. Ihuza neza nubuso budasanzwe (nka chip ya elegitoronike na taberi ya batiri) kandi ishyigikira kwishyiriraho byoroshye.

P Isuku ryinshi & Impanuka nke

Graphite isuku igera kuri Kurenza cyangwa bingana na 95% (hamwe n amanota yo hejuru - amanota meza kugeza kuri 99,95%), naho ivu riri munsi cyangwa ihwanye na 0.5%. Kubura umwanda wibyuma bikuraho kwivanga munzira yo gutwara amashyuza, bikarinda kwangirika kwumuriro waho cyangwa kwangirika kwamashanyarazi - bigatuma su

Shyushya - Imyitwarire - Ibyerekezo bikoreshwa (Amakuru manini - Yatwaye Hejuru - Ibihe Byinshi)

Inganda za elegitoroniki / Semiconductor Inganda: Gukwirakwiza Ubushyuhe

CPU Ubushyuhe bwa Terefone zigendanwa / Mudasobwa zigendanwa: Flake grafite itunganyirizwa muri ultra - firime yoroheje yubushyuhe (0.05-0.5mm yuburebure), ifata hejuru ya chip. Ihererekanya vuba ubushyuhe kugirango isusuruke, irinde ubushyuhe bukabije no gutereta inshuro.

Amashanyarazi yubushyuhe bwo kumurika LED: Ifu ya grake ya grake ivanze na ceramics / resin kugirango itange insimburangingo yumuriro, isimbuza aluminiyumu gakondo. Ibi byongera ubushyuhe bwo gukwirakwiza ubushyuhe kandi bikongerera igihe cya LED hejuru ya 30%.

Bat Batteri nshya yingufu: Gucunga Ubushyuhe

Amashanyarazi Amashanyarazi: Flake grafite gasketi ishyirwa hagati ya moderi ya bateri. Mugihe cyo kwishyuza no gusohora, Ubushyuhe bwo hejuru bwa Flake Graphite neza, kwimura ubushyuhe bwo hejuru bwaho muri sisitemu yo gukonjesha vuba kandi bikarinda guhunga ubushyuhe.

Amashanyarazi yimyubakire ya Bateri: Ifu ya grake ya grake ikozwe muburyo bwo kuyobora - ubushyuhe bwumuriro, bushyirwa hejuru ya tab. Ibi icyarimwe bitezimbere itwarwa rya electron hamwe nubushyuhe bwo kohereza ubushyuhe, kugabanya ubushyuhe bwa bateri mugihe cyo kwishyuza / gusohora (Ntibiri cyangwa bingana na dogere 5).

Equipment Ibikoresho byo mu nganda: Hejuru - Gukora Ubushyuhe Ubushyuhe / Gukingira

Imiyoboro yubushyuhe bwa Metallurgical Furnace Linings: Hejuru - isuku ya flake grafite ikozwe mumatafari igashyirwa kurukuta rwimbere rwitanura ryuma. Yihutisha ihererekanyabubasha mu itanura, igera ku gukwirakwiza ubushyuhe bumwe (kugabanya itandukaniro ry’ubushyuhe bwaho kuri dogere 10-15).

Gukwirakwiza Umuyoboro / Ubushyuhe - Gukurikirana ibikoresho: Ifu ya grake ya grake ivangwa hamwe na insuline kugirango ikore ibikoresho bifunga imiyoboro. Igabanya gutakaza ubushyuhe ku bushyuhe buke (insulation) kandi ikorohereza gutwara ubushyuhe bumwe ku bushyuhe bwinshi (tracing tracing), ibereye imiyoboro ya shimi n’ubushyuhe.

Inganda zitwara ibinyabiziga: Gukonjesha ibice

Amashanyarazi ya moteri nshya ya moteri yimodoka: Flake grafite yamashanyarazi yashyizwe hagati yinzu ya moteri na sisitemu yo gukonjesha. Bakwirakwiza vuba ubushyuhe buterwa nigikorwa cya moteri, kuzamura imikorere ya moteri no kugabanya ingufu za 5% -8%.

Kuri - Amashanyarazi (OBC) Gukwirakwiza Ubushyuhe: Flake grafite ya firime ifatanye hejuru yibice bigize OBC imbere, ikemura ibibazo byubushyuhe bwo hejuru - mugihe cyo kwishyuza byihuse no kurinda umutekano wumuriro.

Incamake

Ubu burebure - ubushyuhe - ubwuzuzanye bwa flake grafite ikoresha imiterere ya anisotropique, imiyoboro ihanitse yubushyuhe, igishushanyo cyoroheje, hamwe n’umutekano udasanzwe. Ikora nk'ibikoresho bikomeye byo gucunga amashyanyarazi muri elegitoroniki, ingufu nshya, inganda, n’imodoka, bikemura ibibazo by’ububabare nko gukwirakwiza ubushyuhe buke, ibice biremereye, hamwe n’ibidukikije bikabije.
