1. A method of pumping media in heat exchangers with rotating disc surfaces and cavities between the disc surfaces in a cylindrical housing, for the flow that passes heat exchanger process, entering cavities between heat transfer surfaces at the periphery and exits the cavities through channels in centre of heat exchanger in several parallel cavities which are formed between said surfaces in the cylindrical housing, whereby no leakage occurs between said surfaces and the cylindrical housing, causing the major part of the flowing medium to pass through a rotating flow-mechanical boundary layer adjacent to the rotating transfer surface in lamellar or turbulent flow, said medium or media is introduced to the periphery of the rotating surfaces with the medium or media already in rotation in the rotational direction of said surfaces, said discs are divided into sections by means of partition walls so constructed that said flow is delivered separated from the centre to the periphery, and subsequent to passage over the rotating disc surfaces the flow leaves through channels in the center of the heat exchanger, characterized by that pumping is arranged in one or the same pump or fan embodiment with the same speed of rotation as the heat exchanger, connected to the heat exchanger and giving pumping effect by bringing to rotation the medium entering the heat exchanger and also giving pumping effect by bringing to rotation the medium that leaves the heat exchanger.
