1. The method and system for a convective heat exchange of between two fluids comprising:
a tube for stream of the first working fluid; a set of well heat-conducting flat fins that are stretched along a central core and directed out of said core, while said core has a hole inside it that allows said tube for stream of the first working fluid to fit in, having a reliable heat-conductive contact with said core; a cylindrical well heat-conducting envelope, inside which said tube with attached fins can be placed in such manner that free edge (which is opposite to the fin's edge that is contacting with said tube for stream of the first fluid) of each fin will come in a reliable (in order to provide a good thermal contact with said envelope) contact with inner surface of said envelope; wherein said tube with said set of fins being placed inside said cylindrical envelope forms a cassette of channels: central one—inside said tube, and a multitude of sector-shaped channels for a second fluid, while each of these channels is stretched parallel to the said tube and has the surfaces of two neighbor fins as its side walls, external surface of said core as its bottom wall, and the internal surface of said envelope as its top wall. |
