  We consider two parallel layers of dipolar ultracold Fermi gases at different
temperatures and calculate the heat transfer between them. The effective
interactions describing screening and correlation effects between the dipoles
in a single layer are modeled within the Euler-Lagrange Fermi-hypernetted chain
approximation. The random-phase approximation is used for the interactions
across the layers. We investigate the amount of transferred power between the
layers as a function of the temperature difference. Energy transfer arises due
to the long-range dipole-dipole interactions. A simple thermal model is
established to investigate the feasibility of using the contactless sympathetic
cooling of the ultracold polar atoms/molecules. Our calculations indicate that
dipolar heat transfer is effective for typical polar molecule experiments and
may be utilized as a cooling process.
