    Based on the steady-state flat plate method and the characteristic that ice is prone to melting due to high temperature, we have established an experimental plan to measure thermal conductivity using cold conduction. The influence of the shape and thickness of the insulation layer and ice sample on the measurement of the thermal conductivity of ice is studied through COMSOL software calculation and simulation. The experimental device structure is designed using CATIA software. We have successfully developed an intelligent measurement device for ice thermal conductivity based on Arduino, measuring the thermal conductivity of pure ice, and studying the effects of impurities such as NaCl salt and white sugar at different mass percentage concentrations, as well as the thickness of impurity ice, on the thermal conductivity.
