| titleOfInvention | Electric water heater |
| abstract | Field of technology: Water electric heaters with resistive heating elements immersed in water. Problem to be solved: Increasing the heat-emitting surface, efficiency and power output of the heating element in order to minimize heat loss and optimize the operating temperature of the heating element immersed in water. The essence of the invention: The resistive conductor of the heating element is made of a thin resistive tape (4), the perimeter of the cross- section of which exceeds mainly more than twice the perimeter of the cross-section of a round wire of equal cross-sectional area. The spiral from of tape (4) has a thermally conductive dielectric coating (5), is wound on a carcass of thin-walled cylindrical pipe (3) and forms, respectively, the external and internal heat-emitting surfaces of the heater. On both sides of the heat-emitting surfaces of the heater, gaps (11) are formed for the flow of the heated fluid. The heater may comprise several such cylindrical heating elements concentrically arranged in one another. Alternative solutions: The electric heater may contain flat heating elements with a thin resistive tape, curved in the form of a sinusoid, or in the form of an Archimedes spiral. Cylindrical and flat spiral heating elements can be formed from a flattened tubular shell into which a thin resistive tape with an insulating coating is pressed. |
