The finite difference method is used to solve the three-dimensional temperature field and thermal resistance of the new energy-saving wall block. The calculation of the equivalent thermal conductivity of the air layer is related to the thickness of the air layer, which makes the calculation result more accurately reflect the thermal performance of the wall block . In this paper, many factors that affect the thermal resistance of block are analyzed, and several methods to improve the thermal resistance of block are put forward.
