I-CMC CuMoCu iSinki yoBubushushu
CMC CuMoCu Material Isicelo
IiNqaku zoKwandiswa okuPhantsi kunye neMizila ye-Thermal yeeSinki zokushisa, iiFremu zeNkokeli, iiBhodi zeSekethe eziprintiweyo ezininzi (iiPCB), 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 okushushu kunye nokufudumeza, 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.Ukuqulunqwa kwesakhiwo sezinto eziphathekayo ukusuka phezulu ukuya ngasezantsi: ishidi lobhedu - ishidi le-molybdenum - iphepha lobhedu - iphepha le-molybdenum ... iphepha lobhedu, linokuqulunqwa ngamanqwanqwa angama-5, ama-7 okanye angaphezulu.Xa kuthelekiswa ne-CMC, i-SCMC iya kuba neyona coefficient yokwandisa i-thermal esezantsi kunye neyona ndlela iphezulu yokuqhuba i-thermal.
