Single-tube multi-section liquid metal magnetofluid generator

Abstract

The invention discloses a single-tube multi-section liquid metal magnetofluid generator; three generation channels (3-1, 4-1, 5-1) are vertically arranged under an unidirectional even magnetic field; the first generation channel (3-1) and the second generation channel (4-1) are communicated with a first transition section (6); the second generation channel (4-1) and the third generation channel (5-1) are communicated with a second transition section (7); the other end of the first generation channel (3-1) is communicated with an inlet section (1); the other end of the third generation channel (5-1) is communicated with an outlet section (2); the inlet section (1), the first generation channel (3-1), the first transition section (6), the second generation channel (4-1), the second transition section (7), the third generation channel (5-1) and the outlet section (2) form a channel communication space; liquid metal (8) flows in the channel communication space back and forth, thus cutting magnetic line of force and inducing electromotive force.

Description

Technical field [0001] The invention relates to a liquid metal magnetic fluid generator, in particular to a liquid metal magnetic fluid generator using a single tube and multiple sections. Background technique [0002] The new Liquid Metal Magnetohydrodynamics (LMMHD) generator uses alternating external forces, such as automobile internal combustion force and wave force, to directly drive the liquid metal to reciprocate linearly in the power generation channel, cut the magnetic lines of force, and generate AC electrical energy. Compared with traditional LMMHD power generation systems, such as two-phase flow power generation systems and single-phase flow power generation systems, the new LMMHD generator uses direct drive and single-phase liquid metal power generation working fluid, without additional energy and equipment to maintain a good working fluid Electrical conductivity, simple structure, high power density, and high efficiency, so it has broad application prospects in hybr...

Problems solved by technology

However, Chinese patent 200610144400.5 is a dual-channel structure with only one U-shaped transition section, and its ability to increase the output voltage of the generator is limited, and it is not linear, which greatly limits its application occasions; the 16 power generation units in US patent 0146140A1 are Independent structure, but if the induced currents are not equal due to the unequal force on each unit, the non-uniformity of the series output of multiple power generation units arranged in parallel is a subsequent problem

[0006] Chinese patent 201510661287.7 proposes an annular channel liquid metal magnetic fluid generator, which adopts a channel structure with an annular radial section, and combines the radial uniform magnetic field and the axial flow of liquid metal to increase the output voltage of the generator, that is, reduce the low voltage. It is difficult to convert voltage and high current alternating current to stable and usable electric energy, but the magnet design, processing and installation of the generator are relatively complicated
