Description

The utility model relates to the field of heat power engineering. A device for heating a liquid coolant is intended for heating a liquid coolant in heating systems and hot water supply of various objects of vital activity.

A device for heating a liquid coolant contains a container for a heated liquid, an inductor consisting of a cylindrical element with permanent magnets placed on it with alternating poles around the circumference, the cylindrical inductor and the metal cylindrical container located coaxially, and the cylindrical inductor mounted rotatably in the container with heated liquid around the side surface of the cylindrical inductor mounted fixed metal lattice oaksialno with the inductor, the inductor is driven to rotate by any actuator, such as electric motor, turbine, etc.

A device for converting mechanical energy into thermal energy is known, which comprises a fixed shell and a composite magnetic circuit, one of the parts of which is movable, which is an anchor and carries permanent magnets, and the other part of the magnetic circuit is made in the form of a fixed multi-core charge core. The shell is a closed hollow chamber with through channels in it for placement of core rods in them, the shell has an inlet and outlet nozzles for circulation of the heated medium (for the invention of the Russian Federation No. 2097946, IPC Н05В 6/10) [1]. Such a device consists of a large number of elements, such as a multi-core core, a heat exchanger chamber with closed circuits made of electrically conductive material inside, and an anchor with permanent magnets is difficult to manufacture and will have large mass and size characteristics.

A device for converting mechanical energy into heat (patent for utility model of the Russian Federation No. 97889, IPC Н05В 6/10) [2]. In this device, the technical result is achieved due to the fact that the excitation winding, through which direct current flows, creates a constant magnetic field, while rotating the rotor with the winding, an alternating magnetic field creates eddy currents in the ferromagnetic cylinder, ensuring its heating. The disadvantage of this device is associated with the use of a direct current source to power the field coil, therefore, to ensure the autonomous operation of such a device, a battery is required, which complicates the design and reduces the reliability of the device.

A device for heating a liquid coolant (patent for a utility model of the Russian Federation No. 176672, IPC Н05В 6/10) [3]. On one and the other side of the cylindrical container with a coolant, there is one disk rotatably relative to the container, permanent magnets are placed on the disks around the circumference, while the drives rotate the drives with the drive motor, eddy currents appear in the walls of the container, which heat the container and the coolant inside it. The disadvantage of this device is that when the disks with magnets rotate, air is vented around the tank, so part of the heat is dissipated into the environment and does not go to heat the coolant.

Known vortex wind heat generator (patent for the invention of the Russian Federation No. 2656515, IPC F03D 3/00) [4], containing an orthogonal wind turbine, a converter of mechanical energy into thermal energy in the form of a stirrer with movable blades. In such a device, the heating medium is heated by rotating the stirrer blades in a liquid, while the mechanical energy is expended to overcome the friction forces and is converted into thermal energy. A stirrer with moving blades, working on the principle of the Watt regulator, allows you to adjust the speed of the orthogonal wind turbine to provide the necessary rotational speed of the rotor of the wind turbine at different wind speeds. The disadvantage of this device is that the mixer with moving blades has a complex kinematic scheme, which reduces the reliability of the wind generator.

The closest in technical essence is the device (patent for the invention of the Russian Federation No. 2303861, IPC Н05В 6/10) [5], adopted as a prototype. A device for heating a liquid comprises a liquid container, an inductor consisting of a cylindrical element of magnetic material with permanent magnets placed on its wall with alternating poles around the circumference, the cylindrical element and the metal cylindrical container are arranged coaxially, and the cylindrical element of the inductor is rotatably mounted, this cylindrical element with magnets is placed inside a container with a heated fluid. In such a device, a technical result is achieved by eddy current heating of a container made of an electrically conductive material. The disadvantage of this device for heating the liquid is that part of the thermal energy will be dissipated into the environment, because the outer surface of the cylindrical tank, which is heated by eddy currents, surrounds air with a temperature lower than the temperature of the heated tank.

The purpose of the utility model is to reduce the dissipation of thermal energy into the environment when heating a liquid coolant in heating systems and hot water supply of vital objects.

The utility model is illustrated by drawings.

In FIG. 1 shows a main view of a device for heating a liquid coolant, in FIG. 2 is a top view of a device for heating a liquid coolant.

A device for heating a liquid coolant contains a container 1 for a heated liquid 2, an inductor 3, consisting of a cylindrical element with permanent magnets 4 placed on it with alternating poles around the circumference, with the cylindrical inductor and the metal cylindrical container 1 located coaxially, and the cylindrical inductor 3 installed with the possibility of rotation, in a container with a heated fluid around a side surface of a cylindrical inductor 3, a fixed metal grid 5 of a cylindrical minutes shape coaxially with the inductor, the inductor 3 is driven to rotate by any actuator, such as electric motor, turbine, etc.

The principle of operation of a device for heating a liquid coolant.

The drive 7 provides rotation of the shaft 6, mechanical energy is transmitted to the inductor of a cylindrical shape 5 with permanent magnets 4 placed on it, while rotating the inductor 5, the permanent magnets 4 are moved relative to a fixed metal lattice of a cylindrical shape 5, which is installed inside the tank with a liquid coolant around the side surface of the cylindrical inductor coaxial with inductor. Eddy currents appear in the rods of the metal lattice 5, which ensure its heating. The metal grate is located in the tank with a liquid coolant, therefore, heat energy is transferred from the metal grate 5 to the liquid coolant 2, just as the inductor 4 rotates inside the tank, the coolant 2 is mixed and more uniformly heated.

The technical result achieved by the utility model is to reduce the dissipation of thermal energy into the environment of the source of thermal energy, because the heating element is located in the liquid coolant and its entire surface is in contact with the liquid coolant.

The placement of permanent magnets on the inductor is possible according to various schemes and with a different number of pole pairs: with radial magnetization, with tangential magnetization, with radial tangential magnetization (Halbach cylinder), with V-shaped arrangement of magnets, so as to ensure maximum magnetic field induction with the outer side of the cylindrical inductor, which will increase the heating of the metal lattice by eddy currents.
