heat-power engineering; heating devices for heating various liquids. SUBSTANCE: device is based on release of heat at cavitation in liquid contained in closed volume; liquid flows through cavitation source located in piston moving in this volume; liquid is practically motionless relative to all walls but for walls of cavitation source. EFFECT: enhanced efficiency of converting energy due to reduced expenses for viscous friction against walls; simplified construction; low cost of device due to avoidance of pumps. 3 cl, 2 dwg |
