Ingqikithi Yomkhiqizo

I-graphite ephezulu-eshisayo-ye-conductivity ye-conductivity ikhiqizwa nge-natural flake graphite ngokuhlanza nokubumba (noma{2}}ibanga lokucutshungulwa kwempushana). Isakhiwo sayo esinezendlalelo esiyingqayizivele sithola ukuqhutshwa kwe-thermal okuvelele{4}}inani layo eliyinhloko. Iletha -ukudlulisa ukushisa okusebenza kahle kakhulu, ukulahlekelwa amandla aphansi,{7}}isimo esiguquguqukayo" izixazululo ezishisayo, ukuxazulula izinkinga ze-metallic' (ithusi, i-aluminium) yezindleko eziphakeme/zokuminyana kanye nokunqoba{8}}i-metals' ukuguquguquka okubuthakathaka kwe-thermal, ukugcwalisa ngempumelelo izikhala zemakethe.

Amapharamitha wezobuchwepheshe(Imikhiqizo isekela ukwenza ngezifiso)

Izici Eziwumongo (Kugxile Ekuziphatheni Kwe-Thermal-Izici Ezihlobene)

① I-Anisotropic High Thermal Conductivity

Ukwakheka kwayo okunezingqimba (okufana "namashidi ahlanganisiwe ashisayo e-thermal") kubangela ukuphakama okuphezulu-ekuhambeni kokushisa kwendiza kunokusebenza{1}}kwendiza. Ngaphakathi kwesendlalelo ngasinye, i-High Thermal Conductivity Flake Graphite ngokushesha-eziqhenya ngokusebenza kahle kokushisayo izikhathi ezingu-20-eziphindwe ka-50 kunama-resin avamile. Khonamanjalo, i-cross-plane conductivity thermal conductivity ingenziwa ngendlela edingekayo, iyenze ifaneleke "directional heat dissipation" izimo (isb, ukulawula izinga lokushisa kwasendaweni kwezingxenye ze-elekthronikhi).

② Ukumelana Nokushisa Okuphansi Nokuqina Okuphezulu

Ibonisa-ukumelana nokushisa okuphansi kakhulu (Ngaphansi noma okulingana no-0.15 K·m²/W) phakathi nokudlulisa ukushisa. Ngaphezu kwalokho, phakathi kwebanga lokushisa elingu--200℃kuya ku-600℃, ukuqhutshwa kwayo kwe-thermal kuhlala kucishe kungashintshile, ngaphandle kokuncibilika noma ukubola. Lokhu kuzinza kunika amandla ukusebenza okuthembekile ezindaweni eziphezulu{7}}nezinga lokushisa eliphansi kakhulu.

③ Engasindi futhi Kulula Ukuyicubungula

Ngokuminyana okungu-2.2-2.3 g/cm³ kuphela (cishe u-1/4 wekhopha no-2/3 we-aluminium), ingacutshungulwa ibe izimpushana, amafilimu amancane, ama-gaskets, nezinye izinhlobo. Ivumelana kalula nendawo engajwayelekile (njengama-chips e-electronic namathebhu webhethri) futhi isekela ukufakwa okuguquguqukayo.

④ Ukuhlanzeka Okuphezulu Nokungcola Okuphansi

Ubumsulwa be-graphite bufinyelela Okukhulu noma bulingana no-95% (ngamabanga aphezulu-okuhlanzeka kufika ku-99.95%), futhi okuqukethwe komlotha Kungaphansi noma kulingana no-0.5%. Ukungabi bikho kokungcola kwe-metallic kuqeda ukuphazamiseka endleleni yokuqhuba i-thermal, kuvimbele ukwanda kokumelana nokushisa kwendawo noma ukugqwala kwe-electrochemical{5}}okwenze kube lula.

Ukushisa{{0}Ukuqhuba-Izinhlelo zokusebenza eziqondiswe ku-inthanethi (Idatha Enkulu{2}}I-Driven High{3}}Izimo Zemvamisa)

① Imboni ye-Electronics/Semiconductor: I-Directional Heat Dissipation

Amasinki Okushisa e-CPU Omakhalekhukhwini/Amalaptop: I-Flake graphite icutshungulwa ibe amafilimu-amancanyana ashisayo (0.05-0.5mm awugqinsi), anamathela endaweni ye-chip. Idlulisela ngokushesha ukushisa kuma-fin sinki okushisa, ivimbele ukushisisa kwe-chip kanye nokushayeka phansi.

Ama-Thermal Conductive Substrates Okukhanyisa kwe-LED: I-Flake graphite powder ixubene ne-ceramics/resin ukukhiqiza ama-thermal conductive substrates, esikhundleni se-aluminium substrates yendabuko. Lokhu kuthuthukisa ukusebenza kahle kokulahla ukushisa kokukhanyisa futhi kwelule ubude bempilo ye-LED ngaphezu kuka-30%.

② Amabhethri Amandla Amasha: Ukuphatha Okushisayo

I-Power Battery Thermal Pads: I-Flake graphite gaskets ibekwe phakathi kwamamojula webhethri. Ngesikhathi sokushaja nokukhipha, i-High Thermal Conductivity Flake Graphite isebenza kahle, idlulisela amazinga okushisa enziwe endawo kusistimu yokupholisa ngokushesha futhi ivimbele ukugijima okushisayo.

I-Thermal Conductive Coatings yamathebhu ebhethri: Impushana ye-graphite ye-Flake yenziwe yaba ama-conductive-ama-thermal coatings, asetshenziswa ezindaweni zamathebhu. Lokhu kanyekanye kuthuthukisa ukuqhutshwa kwe-electron nokusebenza kahle kokudlulisa ukushisa, kunciphisa izinga lokushisa lebhethri ngesikhathi sokushaja/ukuchithwa (Ngaphansi noma kulingana no-5 degree).

③ Izinto Zasezimbonini:{0}}Izinga Eliphezulu Lokuqhuba Ukushisa Kwezinga Eliphansi/Ukufakwa Ukushisa

Izendlalelo zokuqhuba ezishisayo ze-Metallurgical Furnace Linings: I-graphite{0}}yokuhlanzeka okuphezulu kwe-flake yenziwa izitini futhi ibekwe ezindongeni zangaphakathi zeziko le-metallurgical. Isheshisa ukudluliswa kokushisa ngaphakathi kwesithando somlilo, ukufeza ukusabalalisa ukushisa okufanayo (ukunciphisa umehluko wokushisa wendawo ngo-10-15 degree).

I-Pipe Insulation/Heat-Izinto Zokulandelela: I-Flake graphite powder ihlanganiswe nama-resin e-insulating ukuze kwakhiwe izinto zokuvala amapayipi. Inciphisa ukulahlekelwa ukushisa emazingeni okushisa aphansi (i-insulation) futhi yenza kube lula ukuqhutshwa kokushisa okufanayo emazingeni aphezulu okushisa (ukulandelela ukushisa), okulungele amapayipi amakhemikhali nawokushisisa.

④ Imboni Yezimoto: Ingxenye Ukupholisa

Amaphedi Ashisayo Wezimoto Ezintsha Zamandla: Amaphedi e-Flake graphite afakwa phakathi kwezindlu zezimoto nezinhlelo zokupholisa. Bahlakaza ngokushesha ukushisa okukhiqizwa ukusebenza kwezimoto, bathuthukise ukusebenza kahle kwezimoto futhi banciphise ukusetshenziswa kwamandla ngo-5% -8%.

-Kushaja Esebhodini (OBC) Ukusabalalisa Ukushisa: Amafilimu e-Flake graphite anamathiselwe endaweni engaphakathi yezingxenye ze-OBC, axazulula izinkinga-zezinga lokushisa eliphezulu phakathi nokushajwa okusheshayo nokuqinisekisa ukuphepha kokushaja.

Isifinyezo

Le graphite ephezulu{{0}eshisayo{1}}yeconductivity ye-conductivity ikhulisa ukwakheka kwayo kwe-anisotropic, i-high conduction thermal, idizayini engasindi, nokuzinza okukhethekile. Isebenza njengento ebalulekile yokuphatha okushisayo kuyo yonke imikhakha ye-elekthronikhi, amandla amasha, izimboni, nezimoto, ukubhekana namaphuzu abalulekile obuhlungu njengokuchithwa kokushisa okungasebenzi, izingxenye zesisindo esinzima, nokungazinzi kwemvelo okwedlulele.
