According to the present invention, the method of heat transfer in a direction, which is reverse to natural convection, includes introduction of an additional pumping substance into the heated area. The pumping substance is incapable to be dissolved in the heat-transfer agent and its boiling temperature is lower than the boiling temperature of the heat-transfer agent. The heat-transfer agent is heated up, the pumping substance evaporates and the vapor pressure of the pumping substance is used to force the hot heat-transfer agent to flow along the branches of the circulating loop. The device for heat transfer in a direction reverse to the natural convection characterized in that its design incorporates technical means intended for vapor condensation of the pumping substance as well as technical means intended for draining that condensate from the condensation area to the evaporation area.
