We considered a mesoscopic superconductor/normal metal (S/N) structure in which the N reservoirs are maintained at different temperatures. It is shown that in the absence of current between the N reservoirs a voltage difference $V_{ T}$ arises between the superconducting and normal conductors. The voltage $V_{ T}$ oscillates with increasing phase difference $\phi $ between the superconductors, and its magnitude does not depend on the small parameter $(T/\epsilon_{ F}).$
