I-CMC CuMoCu iSinki yoBubushushu
CMC CuMoCu Material Isicelo
IiNqaku zoKwandiswa okuPhantsi kunye neeNdlela eziThermal zokuTyalwa koBubushushu, iiFramu eziKhokelayo, iiBhodi zeSekethe eziprintiweyo ezininzi (iiPCBs), njl.
Izinto zokutshona kobushushu kwinqwelomoya, imathiriyeli yokutshona kobushushu kwirada.
CMC Heat Sink eziluncedo
1. I-CMC composite ithatha inkqubo entsha, i-multilayer copper-molybdenum-copper, i-bonding phakathi kobhedu kunye ne-molybdenum iqinile, akukho msantsa, kwaye akuyi kubakho i-oxidation ye-interface ngexesha lokuqengqeleka kunye nokufudumeza okulandelayo, ukwenzela ukuba amandla okudibanisa phakathi i-molybdenum kunye nobhedu lugqwesileyo, Ukuze izinto ezigqityiweyo zibe ne-coefficient yokwandisa i-thermal ephantsi kunye neyona ndlela ihamba phambili ye-thermal conductivity;
2. Umlinganiselo we-molybdenum-copper we-CMC ulungile kakhulu, kwaye ukuphambuka komgangatho ngamnye kulawulwa ngaphakathi kwe-10%; Imathiriyeli ye-SCMC yimathiriyeli ehlanganisiweyo enamaleko amaninzi. Ukubunjwa kwesakhiwo sezinto eziphathekayo ukusuka phezulu ukuya ngasezantsi: ishidi lobhedu - i-molybdenum sheet - i-copper sheet - i-molybdenum sheet ... i-copper sheet, inokuqulunqwa ngamanqwanqwa angama-5, ama-7 okanye ngaphezulu. Xa kuthelekiswa ne-CMC, i-SCMC iya kuba neyona coefficient yokwandisa i-thermal ephantsi kunye neyona ndlela iphezulu yokuqhuba i-thermal.
