Dirichlet`s task is solved for stable of hot liquid stream traveled into infinitely large lenth radial-divergency canal. Are written equation heatchange for moving of liquid (Furie`s equation) and equation of continuity in cilindric coordinates. Is taken in consideration the canal simmetration along axis , heatexchange heatconduction and convection along axis and by heatconduction along axal . In result were obtained correlations for calculation of temperature field and local heat streams on the walls of canal. The solutions were writen by trigonometric and exponential and bessel`s function. Is used bessel`s functions second kind real and staginary arguments broken number of order.
