The peculiarities of a low temperature heat transfer through a
ballistic quantum dot (a double potential barrier) with interacting leads
due to a long-range Coulomb interaction
(in the geometrical capacitance approach) are considered. It is
found that the thermal conductance K shows periodic peaks as a
function of the electrostatic potential of a dot at low temperatures.
At the peak maximum it is 
whereas near the minimum it is
. Near the peak maximum the dependence K(T) is essentially
nonmonotonic at the temperatures correspondent to the level spacing in
the quantum dot.
