FLOW LIQUID ELECTRIC HEATER Russian patent published in 1994 - IPC

FIELD: electrical power engineering. SUBSTANCE: assembled flow-liquid electric heater is joined with the aid of branch pipe 3 to cock of pipe-line. Liquid flowing from cock passes inside cover 2, fills it up and moves to tubular element 9 through which it goes into space of body 1. After liquid fills space of body 1 up it starts going to inlet of tubular member 10. Through this member is moves along spiral into branch pipe 4 and through its hole 11 outside. After filling of tubular members 9, 10 and space of body 1 liquid will go outside though branch pipe 4. Then voltage is fed to current-conducting electric heater, it heats up and heats liquid coming into space of body 1 which is discharged with the stream of heat-transfer agent through tubular member 10 and branch pipe 4 outside. EFFECT: increased efficiency and reliability of heater in fast heating of liquid. 1 dwg
