[0002] As an important grain storage facility, the thermal insulation effect of the grain storage warehouse wall determines the degree to which the stored grain temperature, humidity and insect pests are affected by the external temperature.

There is no device specifically suitable for measuring the thermal conductivity of grain storage warehouse walls.

[0004] Therefore, we combined the structural characteristics of the grain storage warehouse wall and proposed an easy-to-use automatic detection box for the thermal conductivity coefficient of the warehouse wall to solve the above problems. Utility Model Content
