Description

technical field

[0001] The invention relates to a power generating device, in particular to a dual-channel liquid metal magnetic fluid generator. 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 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 prospects in hybrid electric vehicles, distributed power supplies, an...
