Problems solved by technology

However, the series connection of multiple power generation channels not only increases the size, cost and cost of the power generation device, but also increases the contact resistance and the voltage loss of the wiring, and the ability to increase the output voltage is very limited.
In addition, the synchronization of the output of multiple power generation units is also a problem

Abstract

The invention provides an annular channel liquid metal magnetohydrodynamic generator of which an annular magnetohydrodynamic generation cahnnel (2) penetrates through a magnet annular magnetic hole (1-3); and magnetohydrodynamic channel transition segments (6-1, 6-2) are symmetrically connected at the two ends of the annular magnetohydrodynamic generation cahnnel (2). The other end of the first magnetohydrodynamic channel transition segment (6-1) is connected with a first piston cylinder (7-1). The other end of the second magnetohydrodynamic channel transition segment (6-2) is connected with a second piston cylinder (7-2). A first piston (8-1) is coaxially arranged in the first piston cylinder (7-1). A second piston (8-2) is coaxially arranged in the second piston cylinder (7-2) A sealed communicating space is formed by the pistons, the piston cylinders, the magnetohydrodynamic channel transition segments and the annular magnetohydrodynamic generation channel (2), and the communicating space is fully filled with liquid metal (9). Liquid metal (9) flows along an axial direction in the annular magnetohydrodynamic generation channel (2) so that radial magnetic lines of force are cut and tangential induced current is generated.

Description

technical field [0001] The invention relates to a liquid metal magnetofluid generator, in particular to a liquid metal magnetofluid generator adopting a circular power generation channel. Background technique [0002] The new Liquid Metal Magnetic Fluid (Liquid Metal Magnetohydrodynamics, LMMHD) generator uses alternating external forces, such as automobile internal combustion force and wave force, to directly drive liquid metal to reciprocate and linearly move in the power generation channel, cut the magnetic field lines, and generate AC power. Compared with the traditional LMMHD power generation system, such as two-phase flow power generation system and single-phase flow power generation system, the new LMMHD generator adopts direct drive and single-phase liquid metal power generation working fluid, without additional energy and equipment to maintain a good working fluid Conductivity, simple structure, high power density, and high efficiency, so it has broad application pr...
