Karolo ea Alumina Ceramic ea Sisteme ea Leseli
Sebaka sa Kopo
Likarolo tsa li-ceramics tsa aluminium li sebelisoa haholo tsamaisong ea mabone e nang le thepa e phahameng ea mochini, boima bo phahameng, ho roala nako e telele, khanyetso e kholo ea ho kenya letsoho, e thibelang kutu e ntle, e thibelang mocheso o phahameng.
Likarolo tsa alumina ceramics li ka sebelisoa ka mabone le mabone.Thermal conductivity ea alumina ceramic substrates ranges ho tloha 29. 3W / (m · K) ho 35W / (m · K), e leng hoo e ka bang makhetlo a leshome ho isa ho a mashome a mabeli a aluminium substrates.Ha e sebelisoa ho li-LED, li ka tsamaisa mocheso ka mokhoa o phethahetseng le ho eketsa nako ea bophelo ea LED.Haeba e na le radiator e ntle ea ho senya mocheso, ho ke ke ha e-ba le mocheso oa mateano ho hang, o ka fanang ka tšireletso e phahameng bakeng sa lifaha tsa lebone .China ke 'maraka o moholo ka ho fetisisa oa likarolo tsa alumina ceramics.boholo ba alumina ceramic e romelloa kantle ho naha.
