Abstract

The invention discloses a heater armored electric heating tube. The heater armored electric heating tube comprises an electric heating tube body, a mounting base, a magnet strip, a first net cover anda second net cover, wherein the electric heating tube body and one end of the magnet strip are respectively fixedly connected with the mounting base, the magnet strip is arranged at one side of the electric heating tube body, and a gap is reserved between the magnet strip and the electric heating tube body; the first net cover sheathes outside the electric heating tube body, an open end of the first net cover is detachably connected with the mounting base, and a gap is reserved between the inner wall of the first net cover and the outer wall of the heating tube body; and the second net coversheathes outside the first net cover, meshes on the second net cover and meshes on the first net cover are distributed in a misplaced manner, the open end of the second net cover is detachably connected with the mounting base, and a gap is reserved between the inner wall of the second net cover and the outer wall of the first net cover. The heater armored electric heating tube has the advantages that scale can be effectively prevented from being formed on the surface of the tube body, the heating tube is prevented from being unable to dissipating heat due to accumulation of the water scale, and the problems of low thermal efficiency and short service life are avoided.

Description

technical field [0001] The invention relates to the technical field of heating pipes, in particular to a heater armored electric heating pipe. Background technique [0002] Electric heating tube, also known as heating tube, heating tube, scientific name tubular electric heater element, is a metal tube as the shell, and the spiral electric heating alloy wire is evenly distributed along the central axis of the tube. Both ends of the nozzle are sealed with silicone, this metal armored electric heating element can heat air, metal molds and various liquids. The working principle of the electric heating tube is that the heating wire in the metal tube generates heat after being energized, and the heat is transferred to the heating object through the metal shell of the electric heating tube. When the electric heating tube is immersed in water to heat the water, due to the water quality problem, it boils with the increase of the water temperature, and part of the water evaporates, a...
