The electric heating tube can be generally divided into embedded heating and dry air dry heating in a working environment for dry burning.
So what is the difference between these two heating methods? Does it have an effect on the design of the heating tube?
★ Core difference: heat transfer efficiency is different
1.The embedded heating electric heating tube, because it is embedded in a hole, its surface heat is easily absorbed by the mold or module, then the heat transfer effect of the electric heating tube is extremely fast under the embedded heating environment.
2. The bare electric air-heated electric heating tube has a hindrance to the heat transfer of the electric heating tube. Therefore, under the environment of dry air drying and heating, the heat transfer effect of the electric heating tube is very poor.
★ Impact on the design of the heating tube:
Since the heat transfer efficiency is different, the surface load design of the electric heating tube is different. The surface heating design of the embedded heating electric heating tube can be larger than that of the bare air drying heating heating rod.
★ The life of electric heating pipes in 2 working environments is different:
The life of the embedded heating electric heating tube is relatively longer than that of the electric heating tube exposed to the air dry burning, but this is not absolute, and the specific life depends on the actual size and power.
