FIELD: heat engineering.
SUBSTANCE: invention relates to the field of heat engineering and can be used in heating elements for heating water or other liquids in household or industrial heating appliances. The heating element, which is the bottom of the container for heating mainly liquids, includes a metal bottom of variable thickness with a linear heater, mainly electric, attached to it from below or built into the body of the bottom, and along the line of connection or passage of the heater and in the immediate vicinity, the bottom is made of increased thickness compared to with the rest of the bottom. The linear heater can be made in the form of a closed or open ring. The invention also relates to the arrangement of the bottom of a container of variable thickness.
EFFECT: increasing the efficiency of the closed type heating element with increased convection intensity and reduced noise level.
