1. Field of the Invention
The present invention relates generally to the air conditioning technique. Particularly, the present invention relates to the problem of cooling of a fluid that is flowing through a round tube.
2. Description of the Related Art
The last decade of development of the integrated circuits, especially CPUs (Central Processing Unit) and GPUs (Graphic Processing Unit), evidently demonstrated that we have reached the limits of frequencies, at which the traditional air cooling of working processors can provide reliable evacuation of the generated parasitic heat in order to keep said processors within safe domain of their temperatures. It became clear that future progress in the increasing of working frequencies of processors is possible only by implementation of the convective cooling of processors by the circulating fluid coolant, particularly water. Water cooling of servers already became a routine practice in the big Data Centers.
All implemented solutions for water cooling of computers are employing well known and very traditional fans, the general front look of which is shown in
However, the theory of the convective cooling teaches that the most efficient method of cooling of one fluid by another fluid is that, when said fluids are propagating in opposite directions (not in normal directions).
The object of present invention is the method and system that provides a convective air chilling of a fluid, which is flowing in a pipe, in manner when air blows in opposite direction to the direction of the fluid's flow.
SUMMARY OF THE INVENTIONIt is an object of the present invention to teach the method and system for a convective cooling of a fluid by an ambient air in the regime of counter-flow of said substances.
The invented method and system are based on the usage of a novel design of the fan that creates a flow of the ambient air—with hole over its axis, around which the fan's blade-wheel is rotating.

Claims
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.
2. The method and system of claim 1, further comprising said cassette and a fan that has a co-axial hole in its stator, around which a blade wheel can rotate, wherein the central tube of said cassette goes through fan's co-axial hole and rotating blade wheel of fan is pushing the ambient air through set of the sector-shaped channels of said cassette.
3. The hollow fan of claim 2 comprising:
- a straight regular bearing;
- a cylindrical cup with co-axial hole in its bottom that has a diameter matching to the external diameter of said bearing and due to which said cup can be attached to the external surface of said bearing;
- set of blades that are equidistantly attached to said cylindrical cup's external side surface;
- a magnet ring that can be co-axially placed in a niche inside said cylindrical cup, wherein said cylindrical cup with a magnet ring inside of it and said blades attached outside of it form a rotor of made blade wheel, which can freely rotate around said inner part of used bearing;
- a ring of coils, each in a cartridge with a ferromagnetic core and pin shaped electrodes connected with ends of coil, that can be fit co-axially on the top of inner part of said bearing without touching said blade wheel anywhere;
- a toroidal box with set of holes in its bottom that are exactly matching the disposition of said pin shaped electrodes and with electronics that is needed for managing the electric current in coils;
