In the center of the cover and in the opposite side of the stator has an axial hole in which the bearings installed shaft attached to the motor causing it to rotate. On the shaft inside the bell-shaped stator reinforced monolithic cylindrical aluminum rotor, the outer cylindrical surface of which is uniformly dotted with numerous holes, drilled to a depth approximately equal to the diameter of these holes.The shaft holes of the stator is it in the bearings. At the end of a bell-shaped stator and closing the lid has a hole into which is screwed fittings for supplying heated liquid to the device with one hand and tap it on the other hand, US 5188090.A disadvantage of this device is the low efficiency of its work, and the complexity of manufacturing and repair; monolithic monolithic stator and the rotor with this device is made of large and heavy workpieces; when machining them turns out a lot of waste, and the processing associated with the necessity to be mounted on machines cumbersome procurement, which increases labor costs and reduces the accuracy of processing; during long-term operation of the described device, the outer cylindrical surface of the rotor is exposed to cavitation wear is not uniform, and the bands corresponding, presumably, to antinodes of standing sound waves inside the hollow of the stator along a generatrix line of its cylindrical surface; because of this uneven wear is necessary in the repair of the whole device to send a rotor for melting or welding.It is also known a device for heating the liquid containing the stator, having cylindricality, at least two disks mounted on the shaft with intervals between them; on the cylindrical surfaces of disks holes; at the ends of the disks at their peripheries are through holes, L. P. Fominsk “over-unity heat generators, Ukraine, Cherkasy, 2003, S. 379.This solution is taken as the prototype of the present invention.The heated fluid enters the cylindrical cavity of the stator; when rotating the disks at a speed of about 3000 rpm, in the areas of the recesses on their cylindrical surfaces (chambers shapevine) formed microwire, when shelapani which produces a large amount of energy, which leads to heating of the liquid; in addition, it is assumed that the through holes in the disks must also ensure the creation of microwires, but in practice this does not happen; on the contrary, these through holes create significant hydraulic resistance, which requires additional energy for rotation of the rotor and increasing the capacity of the drive; in addition, the camera shapevine, formed by grooves on the cylindrical surfaces of the disks and the adjacent smooth surface of the cylindrical holder, is not effective enough to ensure the efficiency of the device.According to the invention this problem is solved due to the fact that the device for heating the liquid containing the stator having a cylindrical cavity formed by two covers, with openings for inlet and exhaust of the heated liquid and a cylindrical holder, and inserted into the cylindrical cavity, the rotor comprising at least two disks mounted on the shaft with an interval between them, and the discs have grooves on their cylindrical surfaces and openings in their ends at their periphery, the openings in the ends of the disks at their peripheries made deaf and paired with opposing blind holes, additionally performed on the inner surfaces of the covers of the stator grooves on the cylindrical surfaces of the disks associated with opposing recesses, which are additionally performed on the inner surface of the cylindrical casing, and in the interval between the disks placed stationary ring attached to the inner surface of the cylindrical casing and provided with blind holes formed on the end surfaces of the ring, paired with blind holes on the ends of the disks; the area of the cylindrical cavity of the stator near the rotor shaft can be connected to the go sources, contains information about technical solutions, identical to the present invention, which allows to make a conclusion about its compliance with the criterion of “novelty”.Implementation characteristics of the invention provides an important new features of functioning of object (effect). Due to the fact that the holes in the ends of the disks at their peripheries performed blind (deaf) and are associated with opposing blind holes, which are made on the inner surfaces of the covers of the stator creates additional camera shapevine; in addition, additional camera shapevine are formed due to the fact that in the interval between the disks placed stationary ring provided with blind holes on its end surfaces, which are associated with blind holes on the ends of the disk device prototype through holes in the ends of the drive does not constitute cameras shapevine, they only cause some turbulization of the flow of fluid, which, as practice shows test device prototype, which is measured from the inlet of the stator to the output through the through holes in the disks without any significant heat; due to the fact that the indentations on zilitina the surface of the cylindrical casing, significantly increases the efficiency of the vortex and, accordingly, increases the hydraulic energy of microwires and equivalent thermal energy generated during shelapani of microwire; this is because when the sudden increase in the degree of expansion increases the pressure in the chamber shapevine.The applicant has not found any sources of information containing data about the impact of an alleged distinguishing signs on achieved as a result of their implementation of the technical result. This fact allows to conclude that according to this technical solution, the criterion of “inventive step”.The invention is illustrated by drawings, which shows:in Fig.1 is a section through the longitudinal axis of the rotor;in Fig.2 - cover the stator in a perspective view;in Fig.3 - disk in a perspective view;in Fig.4 - fixed ring fixed in a housing in a perspective view.The device for heating the liquid contains a stator having a cylindrical cavity 1 formed by the covers 2 and 3 and the cylindrical holder 4. In the cover 2 has a hole for supplying a heated fluid, in particular water, equipped with the inlet pipe 5, the cover 3 is made overstay in a specific example, two disks 7 and 8, fixed on the shaft 9. In the interval between the disks 7 and 8 are placed stationary ring 10, is attached to the cylindrical holder 4 of the stator. In the discs at their outer cylindrical surfaces of the holes 11. At the ends of the disks at their peripheries performed blind holes 12; on the inner surfaces of the covers 2 and 3 of the stator is made opposite blind holes 13, the centers of which are at the same distance from the Central axis of the shaft 10 of the rotor, and that the centers of the holes 12. The diameters of the holes 12 and 13 are equal. On the inner surface of the cylindrical holder 4 is made opposite recesses 14, paired with grooves 11 disks 7 and 8. The ring 10 provided with blind holes 15, performed on the end surfaces of the ring. Blind holes 15 are at the same distance from the Central axis of the shaft 9, and the holes 12 of the disks 7 and 8. Thus camera shapevine formed by blind holes 12 and 13, 12 and 15 and the recesses 11 and 14. For an additional increase in the heat generation area of the cylindrical cavity 1 of the stator near the shaft 9 of the rotor is connected to a peripheral area of the cylindrical cavity 1 near the cylindrical casing 4 by means of vacuum cups 16 and two highways 17 and 18.The device runs the trail of the crimson 9 with a speed of 3000 Rev/min When this liquid comes into rotation in the cavity 1. The cameras shapevine have microwire, when shelapani which hydraulic energy microwire goes into heat. As the rotor turns, the water in the cavity 1 under the influence of centrifugal forces is released from the shaft 9 to the yoke 4. Thus, in the area of the shaft 9 creates a zone of reduced pressure. In this zone through line 17 and 18 and the vacuum Cup 16 is sucked hot water from the zone of high pressure, where shapevine of microwires and, accordingly, the heat. There is a mixture sucked in hot water with the incoming cold water that significantly increases the energy efficiency of the installation, and also due to failure of the vacuum, prevents failure of the seals of the shaft 9 of the rotor. Through the outlet 6 hot water is supplied to consumers.
