Description

Technical Field

[0001] The utility model relates to the field of fixing structures, in particular to an electric heating pipe fixing structure of an electric heater. Background Art

[0002] An electric heater is an electric heating device used to increase, keep warm, and heat flowing liquid or gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the fluid thermodynamics are used to evenly carry away the huge heat generated by the electric heating element. Electric heating is the process of converting electrical energy into thermal energy.

[0003] Electric heating tube refers to tubular electric heating element. Electric heating tube is an electrical component that converts electrical energy into thermal energy. It uses metal tube as the outer shell (including stainless steel and copper tube), and spiral electric heating alloy wire is evenly distributed along the central axis of the tube. The gap is filled with compacted magnesium oxide sand with good insulation and thermal conductivity, and the two ends of the tube are sealed with silicone. This metal armored electric heating element can heat air, metal molds and various liquids. When using the electric heating tube in the electric heater, the electric heating tube needs to be installed and fixed by a fixed structure.

[0004] However, the fixed structure of the electric heating tube in the existing electric heater is not conducive to convenient assembly and disassembly of the electric heating tube. When the electric heating tube needs to be repaired or replaced, it will affect the work efficiency of repairing and replacing the electric heating tube, which is not conducive to repairing and replacing the electric heating tube and is not convenient for using the electric heating tube.

[0005] Therefore, we propose an electric heating tube fixing structure for an electric heater. Utility Model Content
