Abstract: At present, there is little research on the application of nano solid materials in low temperature environment, and the performance research of related materials is not perfect. Therefore, the low temperature heat capacity performance of nano solid materials is studied. Set the temperature environment: -10°C-2°C, -2°C-2°C and 2°C-10°C to test the performance of different materials. The experimental results show that the heat absorption capacity: at -10°C-2°C and -2°C-2°C, nano Cu solid material > nano Fe solid material > Nano Al solid material; at 2°C-10°C, nano Fe solid material > nano Cu solid material; heat dissipation capacity: at -10°C-2°C and -2°C-2°C, nano Fe solid material > NANO Al solid material > Nano Cu solid material; at 2°C-10°C, nano Al solid material > nano Fe solid material; low temperature heat capacity index: nano Fe solid material > nano Al solid material > nano Cu solid material.

Keywords: nano-solid materials; specimen preparation; performance test; heat absorption capacity; heat dissipation capacity; low-temperature heat capacity index.
