the strong energy dependence of the supercurrent in superconducting proximity systems. In this work, we predicted that one may induce a finite heat current in the system by tuning the supercurrent flowing in it, either by externally applying it or controlling it via a magnetic flux. This supercurrent-controlled heat current results at suitable circumstances in a measurable cooling of the normal metal.
