All of them are characterized by the presence of an electric motor, a coupling, an annular chamber, a common frame for mounting equipment and a pipe system for supplying and discharging liquid.

A known method of heating a liquid and a device for its implementation [patent RU: No. 2150055], comprising a rotor including a shaft installed in the bearings, and at least one impeller connected to the shaft, made in the form of a disk with a peripheral ring grid, in which a series of fluid outlet openings, a stator with a concentric impeller mesh, in which a series of fluid outlet openings, a stator with a concentric impeller wall, an inlet for supplying fluid and an outlet m; means for driving a rotor with a design speed.

Also known is a rotary pump - a heat generator [RU patent: No. 2159901], comprising a hollow body with a suction pipe for supplying a heated fluid and a discharge pipe for draining a heated fluid. Inside the housing there is a rotor in the form of a double-flow centrifugal wheel with holes on the periphery. Concentric to the rotor is a stator with holes. The holes in the rotor are made in the form of round-cylinder venturi nozzles, and the holes in the stator in the form of suddenly expanding nozzles.

Also known is a heat generator for heating a liquid [patent RU: No. 2232357], including at least one means for accelerating the movement of liquid and at least one means for inhibiting the movement of liquid arranged in the form of paddle wheels located in the housing. One impeller is mounted rotatably under the action of the drive coaxially with another, which is mounted motionless with the formation of a gap between the blades of the impellers. Moreover, according to the first embodiment, a partition is installed in the grooves between the blades of the fixed impeller wheel with the possibility of its movement along the height of the blade. According to the second embodiment, the hub of the rotating impeller is designed so that the distance between its end face of the impeller is equal to ј of the height of the blade.

Closest to the proposed utility model is a device for heating a liquid [patent RU: No. 2233409], comprising a stator having a cylindrical cavity formed by two covers provided with holes for supplying and discharging a heated fluid and a cylindrical cage, and also a rotor inserted into the cylindrical cavity, containing at least two disks mounted on the shaft with an interval between them, the disks have recesses on their cylindrical surfaces and openings at their ends at their periphery, openings at the ends of the disks at their the periphery is made blind and paired with built-in blind holes, which are additionally made on the inner surfaces of the stator covers, the recesses on the cylindrical surfaces of the disks are paired with counter grooves, which are additionally made on the inner surface of the cylindrical cage, and in the interval between the disks there is a fixed ring attached to the inner the surface of the cylindrical cage and provided with blind holes made on the end surfaces.

The disadvantage of the closest analogue is the lack of efficiency and excessive complexity in the manufacture.

The objective of the claimed utility model is to increase the efficiency of heating the liquid with ease of manufacture.

The problem is solved by this utility model in that the device for heating the liquid comprises a rotor including a shaft mounted in the bearings and at least one impeller connected to the shaft (see figure 2), made in the form of a disk with a peripheral annular wall, in which a number of fluid outlet openings 4 are arranged uniformly spaced around and provided with blind holes 5 (3, 7), a stator with a concentric impeller wall (see FIG. 1), an inlet for supplying fluid 1 and 2 in communication with cavity an impeller, and at least one fluid outlet; means for driving a rotor with a design speed. The outlet openings 4 of the impeller (see FIG. 2) are made as an expanding cone 8 at the end of the channel 9 with a cylinder 10 welded into this hole perpendicular to the flow of water with a diameter equal to the section of the main channel 9 (see FIG. 4), similarly in fixed ring (see figure 3) of the hole 6 have a conical extension 8 and the cylinder 10 (see figure 4).

A heat steam generator having a hollow body with a suction pipe for supplying a heated fluid and a discharge pipe for draining heated fluid, a rotor in the form of a centrifugal wheel with holes along the periphery and a stator with holes installed coaxially to the rotor, characterized in that the holes are radially drilled therein suddenly embroidered conically to the exit to the outer part, also holes drilled conically expanding in the rotor are also drilled.

When the rotor and stator openings exit to the outside in expanding conically, the cylinders are flush-welded, with a diameter equal to, for example, the diameter of the opening at the apex of the cone.

The essence of the utility model is illustrated by drawings, which depict:

figure 1, the stator cover;

figure 2 drive;

figure 3 fixed ring, mounted in a cage;
