摘要

The problem of modeling a flat rectangular channel of a solar water heater filled with water during its freezing is considered to estimate the stresses arising in the channel walls. A mathematical model of the deformation of the wall of such a channel during partial freezing of water in it is developed. The theory of elastic cylindrical bending of a two-layer plate is used for modeling. Calculation relationships are obtained for determining the stresses in the channel walls depending on the thickness of the freezing ice. An example of calculating the stresses in the channel walls during water freezing is given. Based on the calculation results, the stresses arising in the metal wall of the solar water heater channel during water freezing are determined.
