The problem on determination of the temperature field 
in the cross section of a thermal tube intersecting the zone of heat 
transfer to the outer surface of the tube has been solved with regard 
for the inhomogeneity of the boundary conditions on the outer surface 
of this tube and the materials from which the body and wick of the 
tube are made. It has been established that the temperature difference 
along the angular coordinate of nonmetal tubes with a very inhomogeneous 
heat transfer on their outer surface does not exceed 0.5 K, while 
this temperature difference in nonmetal tubes is more significant 
under adequate conditions.
