Thermal insulation strategy for thermos cups
1. Ways of heat dissipation The main ways of heat loss are heat conduction, heat radiation, and heat convection. Thermal conduction refers to the transfer of heat from a high-temperature substance to a low-temperature substance through a medium. Thermal radiation is electromagnetic wave radiation caused by heat, which transfers energy to the outside world in […]
