FIELD: cavitation and vortex heat generators; heating liquids in various hydraulic systems; activation of mixing, dispersion and chemical interaction processes. ^ SUBSTANCE: proposed hydrodynamic heat generator is provided with liquid accelerator made in form of bladed impeller at guaranteed small clearance; it is mounted in circular bush provided with tangential passages located over periphery and used for connecting the peripheral surface of impeller with vortex cylindrical chambers found in bush through longitudinal slots in their lateral surfaces. Mounted at outlet of cylindrical vortex chambers are accelerating packings extending to braking chamber where cavity resonators are arranged. Bladed impellers may be of different types: open or closed-type centrifugal impellers at angle more than 90 deg. and centrifugal vortex impellers; vortex and braking chambers may be also made in different versions. ^ EFFECT: low losses of energy; enhanced stability of cavities; enhanced efficiency. ^ 15 cl, 5 dwg |
