I-Ceramic Heat Sink

Incazelo emfushane:

I-Ceramic heat sink ikakhulukazi yakhiwe ungqimba lokukhipha ukushisa kanye nesendlalelo sokushisa ukushisa, isendlalelo sokushabalalisa ukushisa ukusetshenziswa kwesimiso sokushintsha kwamakhemikhali sesigaba se-liquid kuya ku-latex slurry ukuhlakazeka okungalingani, ukwakheka kwe-ceramic powder isakhiwo esincanyana, futhi sihlanganiswe ne-sub-micron. i-powder, bese iqhunyiswa kungqimba olungenalutho lwe-crystal cavity isakhiwo sokushisa, i-porosity yesakhiwo esincane se-cavity ye-heat dissipation layer phakathi kuka-5% no-40%, Usayizi wezinhlayiyana zempushana uphakathi kuka-90 nm no-300 nm.Indawo yokuthintana nomthombo wokushisa inesendlalelo se-thermal conductivity, esimunca futhi siqhube umthombo wokushisa.Ngokusebenzisa indawo ephezulu yesakhiwo se-porous sengqimba yokushisa ukushisa, amandla okukhipha ukushisa athuthukiswa ngokusebenzisa umoya njengendlela yokushisa ukushisa.

Isigaba

I-ceramic heat sink iyisisetshenziswa esihlakaza ukushisa ezingxenyeni ze-elekthronikhi ezithambekele ekushiseni zento kagesi.Njengamanje, ishidi le-alumina ceramic elivame ukusetshenziswa, ishidi le-aluminium nitride ceramic, ishidi le-silicon carbide ceramic.

Ishidi le-alumina ceramic: Inokusebenza kahle kwe-thermal, i-thermal conductivity: 24W / MK, izinga lokushisa eliphezulu / ukumelana nokucindezela okukhulu, ukushisa ngokulinganayo, ukuchithwa kokushisa okusheshayo.Ngaphezu kwalokho, inesakhiwo esilula futhi esihlangene, usayizi omncane, indawo ebushelelezi, amandla aphezulu futhi akulula ukuphuka, ukumelana nokugqwala kwe-asidi ne-alkali, okuhlala isikhathi eside.

Ishidi le-aluminium nitride ceramic: Umbala umpunga omhlophe, indawo ebushelelezi, ungenziwa ngokwezifiso ube yinoma yikuphi ukuma noma usayizi, kulula ukuwusebenzisa nokufaka.Le radiator ye-ceramic ine-conductivity ephezulu kakhulu ye-thermal, i-thermal conductivity yizikhathi ezingu-7-10 zeshidi le-alumina ceramic, ingafinyelela ku-180W ukuphakama, ukusebenza kwayo kokufakwa kukagesi kuzinzile kakhulu, ukulahlekelwa kwe-dielectric kanye nokulahlekelwa okuphakathi kuphansi, kungakwazi ukumelana no-1800 degrees Celsius futhi akuthinti ukusebenza komkhiqizo.Ngokuthuthuka okusheshayo kwemishini ye-elekthronikhi, isidingo semikhiqizo ye-elekthronikhi noma eyisizayo siyakhula, futhi izinga lokusetshenziswa kwalo mkhiqizo njengeshidi le-aluminium nitride ceramic conductivity elishisayo njenge-matrix noma impahla yokupakisha liya ngokuya likhula emakethe. .

Ishidi le-silicon carbide ceramic: Kuyizinto eziluhlaza zokuvikela imvelo, kungokwesakhiwo se-microporous, endaweni efanayo yeyunithi ingaba ngaphezu kwe-30% ye-porosity, yandisa kakhulu indawo yokushisa ukushisa kanye nokuxhumana komoya, ukuthuthukisa umphumela wokushisa ukushisa.Ngesikhathi esifanayo, amandla ayo okushisa amancane, isitoreji sayo sokushisa sincane, ukushisa kungadluliselwa emhlabeni wangaphandle ngokushesha, izici eziyinhloko ze-ceramic heat sink: ukuvikelwa kwemvelo, ukufakwa kwe-insulation kanye nokumelana nokucindezela okukhulu, ukuchithwa kokushisa okuphumelelayo. , ukugwema ukuzalaniswa kwezinkinga ze-EMI.Ingakwazi ukuxazulula ngokuphumelelayo izinkinga zokuqhuba ukushisa kanye nokuchithwa kokushisa embonini ye-electronics kanye nemishini yasendlini.Ngesikhathi esifanayo, ifaneleka ngokukhethekile ukusetshenziswa kwamandla wattage amancane naphakathi.Isikhala sokuklama sinaka imikhiqizo ekhanyayo, emincane, emifushane nemincane, enganikeza ukwesekwa kwezobuchwepheshe kanye nesicelo sokusungula nokuthuthukiswa kwemikhiqizo ye-elekthronikhi.
