Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a fixed storage tank heater. Background Art

[0002] The electric heater converts electrical energy into thermal energy to heat the medium to be heated. When it is working, the low-temperature medium enters its input port through the pipeline under pressure, takes away the high-temperature heat energy generated by the electric heating element during operation, and raises the temperature of the medium to be heated. The high-temperature medium is obtained at the output port of the electric heater. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated by the electric heating element during operation is evenly taken away by the principle of fluid thermodynamics, so that the temperature of the heated medium meets the user's process requirements.
