Description
Technical Field
The invention relates to the field of thermoacoustics, in particular to a thermoacoustics driven corrugated pipe generator.
Background
The thermoacoustic generator consists of two parts, thermoacoustic engine and linear generator. As shown in fig. 1, the thermoacoustic engine mainly includes a heater 1, a regenerator 2, and a water cooler 3. The linear generator mainly comprises a piston 4, a rotor 5, a permanent magnet 6, a coil 7, an inner stator 8, an outer stator 9, a cylinder 10 and the like. When the temperature of a heater 1 in the thermoacoustic engine rises, a water cooler 3 keeps a certain temperature, a temperature gradient is established in the axial line direction of a heat regenerator 2, when the temperature gradient reaches a certain value, gas in the system can generate self-excited oscillation, and the engine converts heat energy into mechanical energy in the form of sound waves. The sound wave can push the piston 4 in the linear generator to move, because the mover 5 and the permanent magnet 6 are fixedly connected with the piston 4, the piston 4 moves to drive the mover 5 and the permanent magnet 6 to move, so that the magnetic flux in the coil 7 is changed, and the mechanical energy is converted into electric energy to be output. In order to improve the heat exchange performance of the engine, lubricating oil cannot exist in the thermoacoustic engine, so that the cylinder 10 and the piston 4 in the linear generator cannot be lubricated by the lubricating oil. The piston 4 and the mover 5 of the linear generator can be supported only by means of a plate spring or an air float, and thus a gap of the order of 10 μm must be maintained between the piston 4 and the cylinder 10, which causes great difficulty in processing and assembly.
In order to solve the above problems, the conventional method is to couple the liquid metal magnetohydrodynamic generator with the thermoacoustic engine. The liquid metal mhd generator is a mechanical energy to electrical energy conversion device without any moving parts, as shown in fig. 2, a magnetic pole 13 is arranged in one direction of a flow channel, when conductive liquid metal 11 flows through the magnetic pole 13, dry sound current is generated in a direction perpendicular to a magnetic field, and electrical energy can be output outwards as long as electrodes 12 are arranged on two sides of the flow channel in the direction perpendicular to the magnetic field. If the liquid metal is placed in the U-shaped pipe, and then the U-shaped pipe is connected with the thermoacoustic engine, the sound wave generated by the thermoacoustic engine can push the liquid metal 11 to reciprocate through the magnetic field, thereby generating electric energy. However, because the liquid metal can flow, the whole liquid metal magnetohydrodynamic generator cannot be inclined or inverted excessively, and meanwhile, if the movement amplitude of the liquid metal 11 is excessively large, liquid levels at two ends are unstable and liquid separation occurs, so that the normal operation of the liquid metal magnetohydrodynamic generator is influenced.

The sealed space is provided with a magnetic pole 13 and an electrode 12.
In the working process, the thermoacoustic engine converts heat energy into mechanical energy in the form of sound waves, and the sound waves can push the corrugated pipe sealing harmonic oscillator to move. Due to the good expansion and contraction of the bellows 14, when the gas pushes the resonator plate 15 on one side to move, the resonator plate 15 on the other side will perform the same movement, thereby driving the liquid metal 11 to flow in the sealed space. If the liquid metal 11 passes through the magnetic field formed by the magnetic poles 13 during the flowing of the liquid metal 11, an induced current is generated in the magnetic field, and the electrode 12 collects the induced current in the magnetic field, so that the mechanical energy can be effectively converted into electric energy.
Because the liquid metal 11 is sealed in the bellows 14, the direction of the thermoacoustic drive bellows generator is not limited, so that the whole structure can not be affected even if the whole structure is turned upside down.
