I-thermal conductivity enhle kakhulu, i-coefficient elawulwayo yokwanda okushisayo kanye nokuhlanzeka kwezinto ezibonakalayo okuvelele. Kucace kahle: Imikhiqizo yethu yemboni yezogesi inezinto ezibonakalayo ezikhethekile kakhulu. Asetshenziswa njengamapuleti ayisisekelo kanye nezisakazi zokushisa, aqinisekisa ukwethembeka kwemishini kagesi.

Uma uthi nhlá, iqiniso lokuthi izingxenye zikagesi zikhiqiza ukushisa ngeke libonakale liyinto yokukhathazeka ngayo. Namuhla, cishe noma iyiphi ingane yesikole ingakutshela ukuthi izingxenye zekhompiyutha ziyafudumala kuyilapho ivuliwe. Ngenkathi idivayisi isebenza, ingxenye yamandla kagesi anikeziwe ilahleka njengokushisa. Kodwa ake sibhekisise: Ukudluliswa kokushisa nakho kungavezwa njengokuhamba kokushisa ngeyunithi ngayinye (ye) yendawo (i-heat flux density). Njengoba izibonelo ezikugrafu zibonisa, ukuminyana kokushintshashintsha kokushisa ezingxenyeni eziningi ze-elekthronikhi kungaba ngokwedlulele. Ukuphakama njengokungathi ku-rocket nozzle emphinjeni lapho amazinga okushisa afinyelela ku-2 800 °C angase aphakame.

I-coefficient yokunwetshwa kwe-thermal ingenye into ebalulekile kuwo wonke ama-semiconductors. Uma i-semiconductor kanye nokokusebenza kwe-base plate kunwetshwa futhi kunkontileka ngamanani ahlukene lapho kuvezwe izinguquko kuzinga lokushisa bese kuba nezingcindezi zomshini. Lokhu kungase kulimaze isemiconductor noma konakalise ukuxhumana phakathi kwe-chip nesisabakazi sokushisa. Nokho, ngezinto zethu zokwakha, uyazi ukuthi usezandleni eziphephile. Izinto zethu ezisetshenziswayo zine-coefficient ephelele yokunwetshwa okushisayo kokujoyina ama-semiconductors nama-ceramics.

Njengamapuleti esisekelo se-semiconductor, isibonelo, izinto zethu zisetshenziswa kuma-turbines omoya, izitimela kanye nezicelo zezimboni. Kumamojula we-semiconductor wamandla we-inverters (thyristors) kanye nama-diode amandla, adlala indima ebalulekile. Kungani? Ngenxa ye-coefficient yawo ephezulu yokunwetshwa kokushisa kanye nokuhamba kahle kokushisa, amapuleti ayisisekelo e-semiconductor akha isisekelo esiqinile se-silicon semiconductor ebucayi futhi aqinisekisa impilo yesevisi yemojuli engaphezu kweminyaka engama-30.

Izisabalalisi zokushisa namapuleti esisekelo enziwe nge-molybdenum, i-tungsten, i-MoCu, i-WCu, i-Cu-Mo-Cu kanye ne-Cu-MoCu-Cu laminates ahlakaza ngokuthembekile ukushisa okukhiqizwa ezingxenyeni zikagesi. Lokhu kokubili kuvimbela ukushisisa ngokweqile kwamadivayisi kagesi futhi kwandisa ukuphila komkhiqizo. Izisakazi zethu zokushisa zisiza ukugcina indawo epholile, isibonelo, kumamojula e-IGBT, amaphakheji e-RF noma ama-LED chips. Senze into ekhetheke kakhulu eyinhlanganisela ye-MoCu yamapuleti esithwali kuma-chips e-LED. Lokhu kune-coefficient yokwanda okushisayo okufana nesafire nezitsha zobumba.

Sihlinzeka ngemikhiqizo yethu embonini ye-electronics ngezinhlobonhlobo zama-coatings. Zivikela okokusebenza ekugqwaleni futhi zithuthukise ukuxhumana kwe-solder phakathi kwe-semiconductor nezinto zethu.
