The typical structure of single-ended electric heat pipe (the most popular structure) is the same as that of electric heat pipe, which generally consists of five parts: insulator, sealing material, lead rod, filler, electric heating wire, metal sleeve and wiring end. The spiral electric heating wire and the lead-out band are located in the center of the metal casing. Its manufacturing process is to penetrate the spiral electric heating wire into the seamless steel pipe, copper pipe or aluminium pipe. The gap between the spiral electric heating wire and the lead-out band is evenly filled with both insulating and heat conducting oxidizing medium through a multi-tube filler. The single-end heating pipe is like crystalline magnesia powder (or alumina or clean quartz sand, etc.). Then the tube diameter is reduced by shrinking machine to make the oxide medium dense (the density is more than 3.3g/cm3), which ensures that the electric heating wire is isolated from the air, and the center position does not deviate and touches the tube wall. So. The calorific value per unit area can be increased by more than ten times. The service life can also be increased to more than 10 years accordingly. Compared with the same high-calorie electrothermal components, the tubular electrothermal tube can save 5% of the electrothermal materials, and the thermal efficiency can reach more than 90%.

1. Shape: Single-end electric heat pipe is one end (one end) outlet line, and ordinary electric heat pipe is two ends outlet line.

2. Internal structure: The winding mode of single-ended electric heat pipe is different from that of ordinary electric heat pipe, especially the imported single-ended electric heat pipe, which is very different from the ordinary electric heat pipe.

3. Manufacturing process: There are more processes in the process of making single-ended electric heat pipe than ordinary electric heat pipe, such as shrinkage pipe, which ensures that single-ended electric heat pipe has higher power and longer service time than ordinary electric heat pipe.
