Description

Technical Field

[0001] The utility model belongs to the technical field of electric heaters, and in particular relates to an immersion type electric heater. Background Art

[0002] Electric heater is an internationally popular electric heating device. It is used to heat up, keep warm and heat the flowing liquid and gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated by the electric heating element is evenly taken away by the principle of fluid thermodynamics, so that the temperature of the heated medium reaches the user's process requirements;

[0003] After searching, the existing patent number CN210107028U discloses a high-pressure economical natural gas electric heater, the main components of which are U-shaped electric heating tube, container, sleeve, oil collection chamber, wiring cavity tube sheet B, tube sheet flange B, PTFE pad, and fastening screws. The characteristics are: one end of the sleeve is closed, and the other end is a through hole. It is made of S30408 ​​stainless steel. The U-shaped electric heating tube extends into the sleeve, and the heat-conducting oil in the oil collection chamber flows into the sleeve. The two wiring ends of the U-shaped electric heating tube extend into the two through holes of the fastening screws, and the external thread of the fastening screw matches the internal thread on the wiring cavity tube sheet B. When the U-shaped electric heating tube is energized, it emits heat, which is transferred to the container to heat the high-pressure natural gas. The high-pressure natural gas does not directly contact the U-shaped electric heating tube, and the U-shaped electric heating tube is not easily damaged;

[0004] In the current existing technology, after a common electric heater is plugged into a heating casing, one end of the heater is exposed, i.e., its outer side has no protective components, which makes it prone to wear and tear such as accidental collision, affecting the use effect. Therefore, it is necessary to design an immersion electric heater to solve the above problem. Utility Model Content
