I-Ceramic Heat Sink

Inkcazelo emfutshane:

Isinki yobushushu beCeramic ubukhulu becala yenziwe ngumaleko wokulahla ubushushu kunye nomaleko wokuqhuba ubushushu, umaleko wokulahla ubushushu kusetyenziso lwesigaba solwelo sotshintsho lwekhemikhali umgaqo ukuya kwi-latex ludaka lokusasazwa okungalinganiyo, ukwakheka komgubo weceramic isakhiwo esibhityileyo, kwaye sidityaniswe ne-sub-micron. umgubo, kwaye emva koko udutyulwe kwisakhiwo sekristale esingenanto kwisakhiwo sokushisa ubushushu, i-porosity yesakhiwo somgobo omncinci womgangatho wokushisa ubushushu phakathi kwe-5% kunye ne-40%, Ubungakanani besuntswana lomgubo buphakathi kwe-90 nm kunye ne-300 nm.Umphezulu woqhagamshelwano kunye nomthombo wokushisa unomgangatho we-thermal conductivity, othatha kwaye uqhube umthombo wokushisa.Ngokusebenzisa indawo ephakamileyo yesakhiwo se-porous somgangatho wokushisa ubushushu, amandla okutshatyalaliswa kobushushu aphuculwa ngokusebenzisa umoya njengomthombo wokushisa ubushushu.

Udidi

I-ceramic ye-heat sink sisixhobo esichitha ubushushu obuvela kwiindawo ze-elektroniki ezithandwa ngubushushu zesixhobo sombane.Okwangoku, i-alumina ceramic sheet esetyenziswa ngokuqhelekileyo, i-aluminium nitride ceramic sheet, i-silicon carbide ceramic sheet.

Iphepha le-alumina ceramic: Inokusebenza kakuhle kwe-thermal, i-thermal conductivity: i-24W / MK, ukushisa okuphezulu / ukumelana noxinzelelo oluphezulu, ukushisa ngokulinganayo, ukutshatyalaliswa kobushushu okukhawulezayo.Ukongeza, inesakhiwo esilula kunye nesicwebileyo, ubungakanani obuncinci, indawo egudileyo, amandla aphezulu kwaye akulula ukuphuka, i-asidi kunye ne-alkali yokumelana nokubola, ihlala ihlala njalo.

Iphepha le-aluminiyam ye-nitride ceramic: Umbala ungwevu omhlophe, umphezulu ogudileyo, unokwenziwa ngokwezifiso kuyo nayiphi na imilo okanye ubungakanani, kulula ukuyisebenzisa kunye nokuyifaka.Le radiator ye-ceramic ine-conductivity ephezulu kakhulu ye-thermal, i-thermal conductivity yi-7-10 amaxesha e-alumina ceramic sheet, inokufikelela kwi-180W ephezulu, ukusebenza kwayo kombane kombane kuzinzile, i-dielectric rhoqo kunye nelahleko ephakathi iphantsi, inokumelana ne-1800 degrees Celsius kwaye ayichaphazeli ukusebenza kwemveliso.Ngophuhliso olukhawulezayo lwezixhobo ze-elektroniki, imfuno yeemveliso zombane okanye ezincedisayo nayo iyanda, kwaye izinga lesicelo sale mveliso njengephepha eliphezulu le-thermal conductivity ye-aluminium nitride ceramic njengematrix okanye imathiriyeli yokupakisha iya ikhula ngakumbi nangakumbi kwimarike. .

Iphepha le-silicon carbide ceramic: Yizinto eziluhlaza zokukhusela okusingqongileyo, ziyingxenye yesakhiwo se-microporous, kwindawo efanayo yeyunithi ingaba ngaphezu kwe-30% ye-porosity, yandisa kakhulu indawo yokutshatyalaliswa kobushushu kunye noqhagamshelwano lomoya, ukwandisa umphumo wokushisa ukushisa.Kwangaxeshanye, ubushushu balo buncinci, ukugcinwa kobushushu buncinci, ubushushu bunokudluliselwa kwihlabathi langaphandle ngokukhawuleza, ezona mpawu ziphambili ze-ceramic heat sink: ukukhuselwa kwendalo, ukugquma kunye nokumelana noxinzelelo oluphezulu, ukutshabalalisa ubushushu obusebenzayo. , ukuphepha ukuzala kweengxaki ze-EMI.Inokusombulula ngokufanelekileyo iingxaki zokuqhuba ubushushu kunye nokutshatyalaliswa kobushushu kwishishini lombane kunye nezixhobo zasekhaya.Kwangaxeshanye, ilungele ngokukodwa ukusetyenziswa kwamandla amancinci naphakathi.Indawo yoyilo ihlawula ingqalelo ekukhanyeni, encinci, emfutshane kunye nemveliso encinci, enokubonelela ngenkxaso yobugcisa kunye nesicelo sokwenziwa kwezinto ezintsha kunye nophuhliso lweemveliso ze-elektroniki.
