Dangantakar da ke tsakanin ma'aunin zafin jiki na kayan haɓakawa shine λ = k / (ρ × c), inda k ke wakiltar yanayin zafi na kayan aiki, ρ yana wakiltar yawa, kuma c yana wakiltar takamaiman zafi.
1. Manufar thermal conductivity
A cikin kayan haɓakawa, haɓakawar thermal yana nufin ikon zafi a kowane yanki na yanki a cikin kayan don wucewa ta cikin kayan a kowane lokaci naúrar, wato, canjin zafi. Yawancin lokaci ana bayyana shi ta hanyar kwararar zafi a kowane yanki a kowane lokaci naúrar lokacin da bambancin zafin jiki shine 1K, kuma naúrar shine W / (m·K). Girman tafiyar da zafi ya dogara da yanayin zafi da kuma bambancin yanayin zafi na kayan.
2. Ƙididdigar ƙididdiga ta thermal conductivity
Ƙarfafawar thermal na kayan haɓakawa yana da alaƙa da yawa, ƙayyadaddun zafi da yanayin zafi na kayan aiki, kuma dangantakar da ke tsakanin su shine: λ = k / (ρ × c).
Daga cikin su, k yana wakiltar ƙaddamarwar thermal na kayan aiki, sashin shine W / (m · K); ρ yana wakiltar yawa, naúrar shine kg/m³; c yana wakiltar ƙayyadaddun zafi, naúrar ita ce J/(kg·K). Wannan dabarar ta gaya mana cewa idan muna so mu rage tasirin thermal conductivity na kayan haɓakawa, muna buƙatar rage yawan ƙima, ƙayyadaddun ƙarfin zafi da ƙimar thermal na kayan.
3. Abubuwan da suka shafi thermal conductivity
Tsarin zafin jiki na kayan haɓakawa yana shafar abubuwa da yawa, irin su zafin jiki, kayan aikin kayan aiki (kamar tsarin crystal), abun da ke tattare da sinadarai na kayan aiki, hulɗar kayan aiki, da dai sauransu Bugu da ƙari, yawa, abun ciki na ruwa. , porosity da sauran sigogi na kayan haɓakawa kuma za su shafi tasirin zafi.
