Process for heat transfer between a solid object and a material layer, including the steps of: a) arranging a heat-discharging surface from a heat-receiving surface at a gap (R) for the flow ( 4 ); b) generating a speed difference between the surfaces by providing a relative movement thereof; c) increasing the speed (v<SUB>1</SUB>) of the flow ( 4 ) in the gap (R) compared to the speed of these surfaces (v<SUB>H </SUB>and/or v<SUB>F</SUB>) by the speed difference; d) maintaining a turbulent flow ( 4 ) in the gap (R) and carrying out the heat transfer by this flow ( 4 ). In the apparatus, the heat-receiving surface of the solid object (H) is formed on a structural part, e.g. rotor ( 2 ), which is relatively movably arranged in a housing ( 3 ) compared to the heat-discharging material layer (F). It is provided with a heat-removing unit and/or a heating unit.
