728x90 과학 (Science)/초전도체, 초유체1 [저온물리 실험] Superinsulation (Multilayer insulation) Two major heat sources at ultra low temperature system: heat conduction and heat transfer from radiation. (1) Convective heat transfer: due to high vacuum condition (about $10^-4$ torr), convective heat transfer is almost eliminated (2) Heat conduction: In order to reduce conductive heat, low thermal conductivity materials are used (3) Radiated heat transfer: using superinsulation materials for .. 2022. 11. 11. 이전 1 다음 728x90
