MAGNETOSTRICTIVE HEAT CARRIER Russian patent published in 2019 - IPC C09K5/10 H01L41/20 H01F1/47 H01F1/53 

FIELD: heating equipment.

SUBSTANCE: invention relates to magnetorheological heat carriers for heat exchange refrigeration and air conditioning plants and systems. Magnetorheological heat carrier consists of liquid selected from alcohols, polyatomic alcohols, water, mixtures thereof, polyethylsiloxane, and microparticles of intermetallic magnetostrictive alloy of terbium, dysprosium and iron of composition: Tb_{(0.30–0.44)} Dy_{(0.15–0.30)} Fe_{(0.30–0.50)} concentration 0.1–1.6 wt%. Said microparticles are made in the form of flakes with size from 5 to 64 mcm in length and from 3 to 20 mcm in thickness.

EFFECT: invention provides higher heat conductivity of heat carrier at intensification of heat exchange process.
