The article investigates the problem of steady-state heat transfer in a thin-walled cylindrical tube, along which a liquid moves under conditions of laminar hydraulically stabilized flow. An analytical solution for the temperature distribution in the liquid and the tube material is obtained using a number of Bessel functions. The conditions of a constant temperature of the tube wall and the absence of internal heat sources are considered. Numerical modeling of the temperature field is carried out, which made it possible to visualize the two-dimensional and three-dimensional temperature distribution. It is shown that the cooling of the liquid occurs mainly due to convective heat exchange with the cooled tube wall. The average temperature of the liquid at the outlet, the total heat flux and the effective heat transfer coefficient are determined. The results obtained have applied value for medical and technical thermoelectric cooling systems, in particular where thin silicone biomedical tubes are used. References 9, Fig. 6.
