This invention discloses a low-corrosion chloride molten salt heat transfer and storage medium, method, and application, belonging to the field of molten salt thermal storage technology. The high-heat-capacity, low-corrosion carbonate molten salt heat transfer and storage medium of this invention is composed of 18%~22% potassium chloride, 6%~10% sodium chloride, 1%~3% aluminum powder, 1%~3% magnesium powder, 1%~3% zinc powder, with the remainder being zinc chloride. Its key feature is the introduction of metal powder into the molten salt, which not only achieves excellent thermal storage performance at 600℃~800℃, but also reduces corrosion by utilizing the potential regulation ability of dissolved metal ions and the formation of highly active [Al] from gaseous chloride products through physical and chemical adsorption. This low-corrosion chloride molten salt heat transfer and storage medium achieves excellent thermal storage performance and low corrosivity, and can be applied in solar thermal power generation and molten salt energy storage.

This utility model relates to a planar magnetic headphone magnet unit with a magnetically conductive structure. It includes a diaphragm, a permanent magnet array, and a support frame. The permanent magnet array consists of multiple strip-shaped permanent magnets symmetrically distributed on both sides of the diaphragm. A magnetically conductive alloy with a permeability μ≥10 is fixedly disposed on the outer side of the non-working surface of each strip-shaped permanent magnet. 4 A soft magnetic material with resistivity ρ≥50μΩ·cm has a U-shaped semi-enclosed cross-section that matches the magnet profile; the magnetic alloy is 0.1-0.5mm thick and has a 0.05-0.2mm gap with the magnet. Optionally, a hollow design is adopted. By constraining the magnetic field diffusion, the magnetic flux density is increased by 18% and the uniformity by 40%. At the same time, the alloy coating reduces the magnet breakage rate by 80%, achieving a synergistic breakthrough in acoustic performance and mechanical reliability.
